Achieve Life Sciences Announces FDA Acceptance of Cytisinicline New Drug Application for Treatment of Nicotine Dependence for Smoking Cessation

Achieve Life Sciences, Inc. (Nasdaq: ACHV), a late-stage specialty pharmaceutical company focused on the global development and commercialization of cytisinicline for treatment of nicotine dependence, today announced that the U.S. Food and Drug Administration (FDA) has accepted the cytisinicline New Drug Application (NDA) for a new treatment for smoking cessation in adults. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) targeted action date of June 20, 2026.

“The FDA’s acceptance of our NDA validates the totality of our product development program,” said Dr. Cindy Jacobs, President and Chief Medical Officer of Achieve Life Sciences. “Our application is supported by a decade of rigorous research and comprehensive data from thousands of participants. We've built compelling scientific and clinical results as a foundation that, if approved, positions cytisinicline to potentially address a significant medical need. We’re eager to engage constructively with the FDA as we progress through the NDA review process.”

The company’s NDA details a comprehensive clinical development program, with more than 2,000 clinical trial participants contributing to the body of evidence. The ORCA-2 and ORCA-3 Phase 3 trials showed cytisinicline administered for either 6 or 12 weeks, alongside standard behavioral support, demonstrated significantly greater smoking abstinence rates by the end of treatment and in long-term abstinence through week 24 as compared to placebo. In addition, safety data will include over 400 participants who have received at least six months of cumulative cytisinicline exposure and over 200 participants receiving at least 1 year of cumulative cytisinicline exposure, with no new safety concerns as reported by the Data Safety Monitoring Committee.

“Smoking is the leading cause of preventable death and disease, claiming the lives of nearly half a million Americans each year, and costing the American economy more than an estimated $600 billion a year,” said Rick Stewart, Chief Executive Officer of Achieve Life Sciences. “The FDA's acceptance of our NDA filing underscores nicotine dependence as an important public health need that demands action. We're energized by this milestone and remain laser-focused on our mission, working toward commercial readiness for the second half of 2026, pending FDA approval. Each year, an estimated 15 million Americans attempt to quit smoking, and we're committed to providing those who are ready to quit a new tool so they can break free from nicotine dependence.”

FDA Approves Kygevvi (doxecitine and doxribtimine) for the Treatment of Thymidine Kinase 2 Deficiency

UCB (Euronext Brussels: UCB), a global biopharmaceutical company, today announced that Kygevvi has been granted approval by the U.S. Food and Drug Administration (FDA) for the treatment of adults and pediatric patients living with thymidine kinase 2 deficiency (TK2d), with an age of symptom onset on or before 12 years.1 It is the first and only approved treatment for these patients living with TK2d.

TK2d is an ultra

Doxecitine/doxribtimine

-rare, life-threatening, genetic mitochondrial disease characterized by progressive (worsening over time) and severe muscle weakness (myopathy) with no approved treatment options beyond supportive care until now.2,3,4,5 It is often fatal, with those experiencing initial symptoms on or before the age of 12 years facing a high risk of premature death (often occurring within 3 years after symptom onset).6 It is estimated that the worldwide prevalence of TK2d is 1.64 [0.5, 3.1] cases per 1,000,000 people.7

“The approval of doxecitine and doxribtimine represents a pivotal moment for the TK2d community who previously had no FDA-approved treatment options for this rare genetic mitochondrial disease beyond supportive [palliative] care,” said Donatello Crocetta, Chief Medical Officer at UCB. “We extend heartfelt thanks to the patients, families and friends, advocates, healthcare providers and dedicated clinical trial teams who have partnered with us on this important journey.”

“It’s hard to overstate the importance of this FDA approval for those diagnosed with TK2d. This is an ultra-rare disease community in dire need of treatment options. For too long, caregivers and their families have had to endure the burden of this disease," said Kristen Clifford, United Mitochondrial Disease Foundation President and CEO. “Having the first-ever FDA-approved therapy for TK2d in this patient population not only meets a critical medical need - it represents something greater - hope for the future."

“I’ve been studying mitochondrial diseases for more than three decades and have witnessed firsthand the impact TK2d has on patients and their families. We have been waiting for an approved treatment for many years, and this approval marks a significant milestone in how we can support and manage this debilitating condition,” said Dr. Michio Hirano, Professor of Neurology and Chief of the Division of Neuromuscular Medicine at Columbia University Irving Medical Center.

Supporting data

The Kygevvi approval is supported by safety and efficacy data from one Phase 2 clinical study, two retrospective chart review studies, and an expanded access use program*.1,8,9,10,11 These studies included a total of 82 unique patients treated with Kygevvi or pyrimidine nucleosides with an age of TK2d symptom onset ≤12 years. Efficacy was assessed by comparing overall survival in these pediatric and adult treated patients to an external control group of untreated patients who were matched to treated patients using age of TK2d symptom onset (≤ 2 years or >2 to ≤ 12 years).1 A total of 78 matched pairs were identified. The results showed that survival time from treatment start was improved; treatment reduced the overall risk of death from treatment start by approximately 86% (95% CI: 61%, 96%).1 Of the 78 treated patients included in the survival analysis, the median age of TK2d symptom onset was 1.5 years (range: 0.01 to 12 years).1 The median duration of treatment was 4 years (range: 1 day to 12 years) and the median dose received was 762 mg/kg/day (range: 260 to 800 mg/kg/day).1

The most common adverse reactions (incidence ≥5%) are diarrhea, abdominal pain (including abdominal pain upper), vomiting, alanine aminotransferase increased (ALT), and aspartate aminotransferase increased (AST).1

A regulatory review of doxecitine and doxribtimine is currently underway by the EMA (European Medicines Agency), and further regulatory submissions are planned. Kygevvi is currently not approved for use in any indication by any regulatory authority outside of the U.S. UCB expects Kygevvi to be commercially available in the U.S. in Q1, 2026. To further its mission of equitable care, UCB will provide a personalized support program for Kygevvi that places the needs of patients and caregivers at the forefront.

In the U.S., Kygevvi received Orphan Drug, Breakthrough, Priority Review and Rare Pediatric Disease designations from the FDA.12,13 With this approval by FDA, UCB was awarded a Rare Pediatric Disease Priority Review Voucher (RPDPRV) redeemable for a priority review for a future marketing application.

About Kygevvi

Kygevvi is a combination of doxecitine and doxribtimine, both pyrimidine nucleosides, indicated for the treatment of thymidine kinase 2 deficiency (TK2d) in adults and pediatric patients with an age of symptom onset on or before 12 years.1 Administration of Kygevvi is intended to incorporate the pyrimidine nucleosides, deoxycytidine and deoxythymidine, into skeletal muscle mitochondrial DNA.1 This action restores mitochondrial DNA copy number in TK2d mutant mice.1

Important safety information for Kygevvi1

Increase in Liver Transaminases

Elevated liver transaminase [alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST)] levels were reported in patients treated with Kygevvi. Obtain baseline liver transaminase (ALT, AST) and total bilirubin levels in patients prior to treatment initiation with Kygevvi. If signs or symptoms consistent with liver injury are observed, interrupt treatment with Kygevvi until liver transaminase (ALT, AST) and total bilirubin levels have either returned to baseline or stabilized at a new baseline value. Consider permanently discontinuing Kygevvi if signs or symptoms consistent with liver injury persist or worsen. Monitor liver transaminases and total bilirubin levels yearly and as clinically indicated.

Gastrointestinal Adverse Reactions

Diarrhea and vomiting leading to hospitalization, dose reduction, and permanent discontinuation were reported in patients treated with Kygevvi. Based on the severity of the diarrhea and/or vomiting, reduce the dosage of Kygevvi or interrupt treatment until diarrhea and/or vomiting improves or returns to baseline. Consider restarting Kygevvi at the last tolerated dose, and increase the dose as tolerated. For persistent or recurring diarrhea and/or vomiting, consider discontinuing Kygevvi permanently and provide supportive care with electrolyte repletion as clinically indicated.

FDA Approves Contepo (fosfomycin) for Injection for the Treatment of Complicated Urinary Tract Infections

The U.S. Food and Drug Administration (FDA) has approved Contepo (fosfomycin) for injection for the treatment of patients 18 years of age and older with complicated urinary tract infections (cUTI), including acute pyelonephritis, caused by susceptible isolates of Escherichia coli and Klebsiella pneumoniae.

Contepo is an epoxide antibacterial that works by disrupting bacterial cell wall synthesis through covalently binding and inhibiting phosphoenolpyruvate transferase (MurA), thereby blocking the synthesis of peptidoglycan. The drug is bactericidal against Enterobacterales.

Dosing and Administration

The recommended dosage of Contepo is 6 grams administered every 8 hours by intravenous infusion over 1 hour in patients 18 years of age or older with an estimated creatinine clearance greater than 50 mL/min. The duration of therapy is up to 14 days and should be guided by the severity of infection and the patient's clinical status. Dosage adjustments are required for patients with renal impairment.

Clinical Trial Results

The FDA approval was based on data from a multinational, double-blind clinical trial (Trial 1) that enrolled 464 adults hospitalized with cUTI, including acute pyelonephritis. The study compared Contepo 6 grams intravenously every 8 hours to piperacillin/tazobactam 4.5 grams intravenously every 8 hours for 7 days of therapy, with treatment allowed for up to 14 days in bacteremic patients.

In the microbiological modified intent-to-treat (mMITT) population of 339 patients, Contepo demonstrated efficacy with regard to overall response at the test-of-cure visit. Overall success, defined as clinical cure plus microbiological eradication, was achieved in 63.5% (108/170) of Contepo-treated patients compared to 55.6% (94/169) of piperacillin/tazobactam-treated patients.

Important Safety Information

The most common adverse reactions (incidence ≥2%) observed in clinical trials were transaminase elevations, hypokalemia, neutropenia, nausea, vomiting, diarrhea, hypocalcemia, hypernatremia, headache, and hypophosphatemia.

Contepo contains 1,980 mg of sodium in each vial. The high sodium load associated with its use may result in changes in serum electrolytes, such as increased levels of serum sodium and decreased levels of potassium, calcium, and phosphorus. A low-sodium diet is recommended during Contepo treatment, and healthcare providers should monitor serum electrolyte levels and fluid status during treatment.

Contepo has been shown to prolong the QT interval in some patients and should be avoided in patients with known QT prolongation or ventricular arrhythmias, including a history of torsade de pointes. Healthcare providers should monitor electrolytes during treatment with Contepo.

Contepo is contraindicated in patients with known serious hypersensitivity to fosfomycin or any of the excipients.

FDA Approves Inlexzo (gemcitabine intravesical system) for the Treatment of Non-Muscle Invasive Bladder Cancer

In continuation of my update on gemcitabine 

Johnson & Johnson (NYSE:JNJ) announced  the U.S. Food and Drug Administration (FDA) approval of  Inlexzo (gemcitabine intravesical system), a new, potentially practice-changing approach for treating patients with certain types of bladder cancer, addressing the need for additional options following unsuccessful BCG therapy and for patients refusing or ineligible for bladder removal surgery (radical cystectomy). Inlexzo, previously referred to as TAR-200, is indicated for the treatment of adult patients with Bacillus Calmette-Guérin (BCG)-unresponsive, non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS), with or without papillary tumors.1

Inlexzo is designed for patients seeking bladder preservation and is the first and only intravesical drug releasing system (iDRS) to provide extended local delivery of a cancer medication into the bladder. Inlexzo remains in the bladder for three weeks per treatment cycle for up to 14 cycles.1 A healthcare professional places Inlexzo into the bladder using a co-packaged urinary catheter and stylet to insert it into the bladder. Inlexzo is placed in an outpatient setting in a few minutes, without the need for general anesthesia or further monitoring immediately post-insertion within the healthcare provider’s office.1

“When we acquired this novel therapy in 2019, our ambition was to give patients with bladder cancer a renewed sense of hope and belief,” said Jennifer Taubert, Executive Vice President, Worldwide Chairman, Innovative Medicine, Johnson & Johnson. “In an area that has seen little progress for more than 40 years, Inlexzo delivers a first-of-its-kind breakthrough innovation with a bright future ahead.”

The approval is supported by data from the SunRISe-1 ( NCT04640623) single arm, open-label Phase 2b clinical study.1 Results show 82 percent of patients with BCG-unresponsive NMIBC treated with Inlexzo achieved a complete response (CR), meaning no signs of cancer were found after treatment (95 percent confidence interval [CI], 72, 90).1 This high response rate demonstrated strong durability, and 51 percent of these patients maintained a complete response for at least one year.1

In the SunRISe-1 clinical trial supporting this approval, the most common adverse reactions (≥15 percent) including laboratory abnormalities, were urinary frequency, urinary tract infection, dysuria, micturition urgency, decreased hemoglobin, increased lipase, urinary tract pain, decreased lymphocytes, hematuria, increased creatinine, increased potassium, increased aspartate aminotransferase (AST), decreased sodium, bladder irritation, and increased alanine transaminase (ALT).1

“I see many patients that ultimately become BCG-unresponsive and often face life-altering bladder removal. These patients now may be ideal candidates for newly approved Inlexzo,” said Sia Daneshmand, M.D., TAR-200 SunRISe-1 principal investigator, and Professor of Urology, Director of Urologic Oncology at the Norris Comprehensive Cancer Center, Keck School of Medicine of University of Southern California.* “In my experience, Inlexzo is well-tolerated and delivers clinically meaningful results. This will change the way we treat appropriate patients that haven’t responded to traditional therapy.”

“We are proud of the science that has brought us to this historic moment,” said John Reed, M.D., Ph.D., Executive Vice President, R&D, Innovative Medicine, Johnson & Johnson. “Inlexzo is a novel therapy with powerful efficacy and demonstrated safety profile. As the only major healthcare company that hosts both pharmaceuticals and medical devices, we leveraged the speed and scale of Johnson & Johnson to accelerate innovation and deliver this important therapy to patients.”

“At BCAN, our mission has always been to advocate for better todays and more tomorrows for everyone impacted by bladder cancer. This approval represents the kind of progress that brings new options to a community that urgently needs them,” said Meri-Margaret Deoudes, CEO, Bladder Cancer Advocacy Network (BCAN).** “Patients with bladder cancer need guidance and collaboration with providers to navigate bladder-sparing treatment options, including newly approved treatments like Inlexzo, so they can move forward feeling well-informed and confident.”

Leading to today’s approval, the FDA granted Inlexzo Breakthrough Therapy Designation (BTD), Real-Time Oncology Review (RTOR), and Priority Review.

Johnson & Johnson is committed to helping patients access our treatments. Once a patient and their doctor have decided that Inlexzo is right for the patient, J&J withMe provides a simple, comprehensive patient support program offering cost support, a dedicated Care Navigator and educational resources, at no cost to the patient.

About SunRISe-1, Cohort 2SunRISe-1 ( NCT04640623), Cohort 2, was a single arm, open-label Phase 2b clinical study that evaluated the safety and efficacy of Inlexzo monotherapy for BCG-unresponsive NMIBC patients with carcinoma in situ (CIS) with or without papillary tumors who are ineligible for, or elected not to undergo, radical cystectomy. The primary endpoint for Cohort 2 was complete response (CR) rate at any time point, and secondary endpoints include duration of response (DOR).

About Non-Muscle Invasive Bladder Cancer (NMIBC) and the Current Standard of Care Non-muscle invasive bladder cancer (NMIBC) is a type of non-invasive bladder cancer that can be classified as low, intermediate, or high risk depending on the presence of characteristics including tumor size, presence of multiple tumors, and carcinoma in situ (CIS).2 NMIBC with CIS makes up approximately 10 percent of patients with NMIBC.3 The current standard of care for NMIBC is Bacillus Calmette-Guérin (BCG), which is a weakened form of the bacteria found in tuberculosis treatment. Though effective, some patients become unresponsive to it and may experience challenges.4,5 Radical cystectomy is currently recommended for NMIBC patients who fail BCG therapy; it is a life-altering surgery with a high degree of morbidity and adverse impact on life, and has a post-surgery mortality rate of three to eight percent.6,7 Given that NMIBC typically affects older patients, many may be unwilling or unfit to undergo radical cystectomy.

About Inlexzo

Inlexzo is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with Bacillus Calmette-Guérin (BCG)-unresponsive, non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS), with or without papillary tumors. Inlexzo is an intravesical system enabling extended release of gemcitabine into the bladder. It is placed in a few minutes without general anesthesia or further monitoring immediately post-insertion within the healthcare provider’s office.

The safety and efficacy of Inlexzo is being evaluated in clinical trials in patients with MIBC in SunRISe-4, and NMIBC in SunRISe-1, SunRISe-3, and SunRISe-

FDA Approves Tonmya (cyclobenzaprine hydrochloride sublingual tablets) for the Treatment of Fibromyalgia

Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP),  announced the U.S. Food and Drug Administration (FDA) approval of  Tonmya™ (cyclobenzaprine HCl sublingual tablets) for the treatment of fibromyalgia in adults. Tonmya is a first-in-class, non-opioid, once-daily bedtime analgesic with a unique sublingual (under the tongue) formulation that is designed for rapid absorption into the bloodstream. Tonmya is the first new FDA-approved therapy for the treatment of fibromyalgia in over 15 years.

“The FDA approval of Tonmya as a first-line treatment for fibromyalgia represents a landmark advancement for the millions of people in the U.S. suffering from the debilitating pain this condition causes,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “At Tonix, we recognized the transformative potential of pursuing a new approach with Tonmya for fibromyalgia, a chronic overlapping pain condition (COPC), that has gone without innovation for many years. We are hopeful that effectively treating pain with Tonmya could help improve the lives of people with this chronic syndrome.”

“The chronic pain of fibromyalgia is debilitating to every aspect of a person’s life, including causing sleep disturbance and fatigue, all of which can negatively impact someone’s ability to carry out their daily activities,” said Sharon Waldrop, a person with lived experience and founder of the Fibromyalgia Association. “For over 15 years, this community has been underserved and waiting for new treatment options. This approval is a promising step forward and brings renewed hope to millions.”

The approval incorporated efficacy from two double-blind, randomized, placebo-controlled, Phase 3 clinical trials of nearly 1,000 patients in total that evaluated Tonmya as a bedtime treatment for fibromyalgia. Across both Phase 3 trials, Tonmya significantly reduced daily pain scores compared to placebo at 14 weeks, the primary endpoint. Additionally, a greater percentage of study participants taking Tonmya experienced a clinically meaningful (≥30%) improvement in their pain after three months, compared to placebo.

Across three Phase 3 clinical trials with over 1,400 patients evaluated, Tonmya was generally well tolerated. The most common adverse events (incidence ≥2% and at a higher incidence in Tonmya-treated patients compared to placebo-treated patients) included oral hypoesthesia (numbness in the mouth), oral discomfort, abnormal product taste, somnolence (drowsiness), oral paresthesia (tingling, pricking or burning in the mouth), oral pain, fatigue, dry mouth, and aphthous ulcer (canker sore).

“For many years, rheumatologists like myself and other healthcare professionals have had to manage fibromyalgia with limited options that do not adequately meet treatment needs for the majority of patients,” said Philip Mease, M.D., Director of Rheumatology Research at the Providence Swedish Medical Center and Clinical Professor at the University of Washington School of Medicine. “Tonmya is a novel treatment approach that targets nonrestorative sleep that is characteristic of fibromyalgia and can impact core symptoms, specifically pain.”

The latest Phase 3 trial, RESILIENT, was recently published in Pain Medicine with data on primary and secondary endpoints measuring pain, patient’s global impression of change, patient-reported symptoms and function, sleep disturbance, and fatigue.

“I know firsthand how the chronic pain of fibromyalgia significantly disrupts my patients’ lives.” Andrea L. Chadwick, M.D., MSc, FASA, Anesthesiology, Pain, and Perioperative Medicine at The University of Kansas Health System. “Treatments that are processed through the liver can result in metabolites that could affect a medicine’s efficacy and safety over time. Tonmya is administered sublingually which is designed to reduce pain quickly and durably with a tolerable safety profile.”

Tonix thanks the participants and investigators involved in its fibromyalgia clinical trials, and FDA for its commitment to approving new treatments for this condition.

Tonmya is expected to be available for adult patients in the U.S. with fibromyalgia beginning in the fourth quarter of this year.

FDA Approves Brinsupri (brensocatib) for the Treatment of Non-Cystic Fibrosis Bronchiectasis

Insmed Incorporated (Nasdaq: INSM),  announced  the U.S. Food and Drug Administration (FDA)  approval of  first-in-class Brinsupri (brensocatib 10 mg and 25 mg tablets), an oral, once-daily treatment for non-cystic fibrosis bronchiectasis (NCFB) in adults and children 12 years and older. Brinsupri is the first and only FDA-approved treatment for NCFB, giving hundreds of thousands of patients and clinicians across the U.S. an option to manage this chronic and progressive disease that can lead to permanent lung damage and lung function decline.

"This FDA approval represents a potential paradigm shift in how we approach non-cystic fibrosis bronchiectasis," said Doreen Addrizzo-Harris, M.D., FCCP, the Fiona and Stanley Druckenmiller Professor of Pulmonary, Critical Care and Sleep Medicine at NYU Grossman School of Medicine and Director of the NYU Langone Health Bronchiectasis and NTM Program, and ASPEN investigator. "For the first time, we have a treatment that directly targets neutrophilic inflammation and addresses a root cause of bronchiectasis exacerbations. Based on the strength of the data and the impact we've seen in patients, I believe this could become the new standard in non-cystic fibrosis bronchiectasis care."

There are approximately 500,000 people in the U.S. diagnosed with NCFB, and it is estimated that millions more are living with this disease globally. Unlike other respiratory diseases that are characterized by airway narrowing, bronchiectasis causes airways to permanently widen, making it harder to clear mucus and bacteria, leading to persistent inflammation and infection. A hallmark of bronchiectasis is frequent exacerbations, or flares, when symptoms worsen, such as coughing, increased mucus, shortness of breath and fatigue.

"Non-cystic fibrosis bronchiectasis deeply affects the lives of people living with this chronic lung condition, impacting both their physical health and emotional well-being," added Elisha Malanga, Executive Director of the Bronchiectasis and NTM Association. "Many patients experience frequent flares, which can disrupt daily life and potentially lead to disease progression. The FDA approval of brensocatib represents a significant and long-awaited advancement as the first approved therapy for non-cystic fibrosis bronchiectasis. Our hope is that treatments like this will enable people with bronchiectasis to manage their condition."

This approval is based on data from the Phase 3 ASPEN and Phase 2 WILLOW studies, which were both published in the New England Journal of Medicine. In ASPEN, patients taking Brinsupri 10 mg or 25 mg had a 21.1% and 19.4% reduction in annual rate of exacerbations respectively, as compared to placebo. Both dosage strengths of Brinsupri also met several exacerbation-related secondary endpoints, including significantly prolonging the time to first exacerbation and significantly increasing the proportion of patients remaining exacerbation-free over the treatment period. Patients who received Brinsupri 25 mg experienced statistically significant less decline in lung function, as measured by forced expiratory volume in one second (FEV₁) after using a bronchodilator, at week 52. The safety of Brinsupri was also evaluated in both studies. The most common adverse reactions ≥2% in the ASPEN trial included upper respiratory tract infection, headache, rash, dry skin, hyperkeratosis, and hypertension. The safety profile for adult patients with NCFB in WILLOW was generally similar to ASPEN, except for a higher incidence of gingival and periodontal adverse reactions in WILLOW.

"The FDA approval of the first-ever treatment for non-cystic fibrosis bronchiectasis is a historic milestone for patients and for Insmed," said Martina Flammer, M.D., MBA, Chief Medical Officer of Insmed. "By keeping patients at the center of everything we do, we have once again delivered a first-in-class medicine for a disease with no prior approved treatments. This is an incredible achievement in medicine. We're deeply grateful to the patients, providers, and advocates who made this possible – this is just the beginning of what we can accomplish together for this community."

Brinsupri is a first-in-class dipeptidyl peptidase 1 (DPP1) inhibitor, designed to inhibit the activation of enzymes (neutrophil serine proteases) in neutrophils that are key drivers of chronic airway inflammation in NCFB. Brinsupri is the first approved therapy to address the underlying inflammatory process of NCFB.

In parallel, applications for brensocatib with the European Medicines Agency (EMA) and the Medicines and Healthcare products Regulatory Agency (MHRA) have been accepted, and the Company plans to file in Japan in 2025. Commercial launches are anticipated in 2026, pending approval in each territory.

Brinsupri is now available in the U.S. by prescription through a comprehensive specialty pharmacy network.

FDA Approves Sephience (sepiapterin) for the Treatment of Children and Adults Living with Phenylketonuria

PTC Therapeutics, Inc. (NASDAQ: PTCT) announced   U.S. Food and Drug Administration (FDA)  approval of Sephience™ (sepiapterin) for the treatment of children and adults living with phenylketonuria (PKU). The approval includes broad labeling for the treatment of hyperphenylalaninemia (HPA) in adult and pediatric patients 1 month of age and older with sepiapterin-responsive PKU.

"We are excited to have reached this important milestone for those affected by PKU," said Matthew B. Klein, M.D., Chief Executive Officer of PTC Therapeutics. "The broad labeling reflects the potential of Sephience to meet the significant unmet need of PKU patients. The Sephience clinical data along with our expertise in launching rare disease therapies position Sephience to become the future standard of care. Our experienced customer facing teams are ready to bring this therapy to children and adults with PKU in the United States as quickly as possible."

The FDA approval is based on the evidence of significant efficacy and safety from the

Phase 3 APHENITY trial as well as durability of treatment effect in the APHENITY long-term extension study.

"The approval marks an exciting milestone for the PKU community," said Catherine Warren, Executive Director of the National PKU Alliance. "This progress brings renewed hope, and we are eager to see the positive impact this new treatment option will have on advancing care and potentially improving quality of life for individuals of all ages and PKU subtypes that respond to this therapy."

Sephience was recently granted marketing authorization by the European Commission. Review of approval applications is ongoing in several other countries including Japan and Brazil.

About Sephience (sepiapterin)

Sephience is indicated for the treatment of hyperphenylalaninemia (HPA) in adult and pediatric patients with phenylketonuria (PKU). Sephience is a natural precursor of the enzymatic co-factor BH4, a critical co-factor for phenylalanine hydroxylase (PAH). Through its mechanism of action, Sephience is able to effectively reduce blood phenylalanine (Phe) levels and has the potential to treat a broad range of PKU patients. Sephience is approved in the European Economic Area and the United States.

Indication and Important Safety Information

Indication

Sephience is indicated for the treatment of hyperphenylalaninemia (HPA) in adult and pediatric patients 1 month of age and older with sepiapterin-responsive phenylketonuria (PKU). Sephience is to be used in conjunction with a phenylalanine (Phe)-restricted diet.

Contraindications

None

Important Safety Information

Treatment with Sephience should be directed by physicians knowledgeable in the management of PKU. Biochemical response to Sephience can only be determined by a therapeutic trial with careful monitoring of ongoing dietary and nutritional balance to ensure adequate Phe control.

Warnings and Precautions

Increased Bleeding: Sephience may increase the risk of bleeding. Bleeding events, including superficial hematomas, prolonged bleeding, and heavy menstrual bleeding have occurred in patients treated with Sephience. Inform patients about the risk of bleeding associated with Sephience and have patients follow up with their healthcare provider should such a bleeding event occur. Consider treatment interruption with Sephience in patients with active bleeding.

Hypophenylalaninemia: Some pediatric patients receiving Sephience experienced hypophenylalaninemia. Monitor blood Phe levels during treatment and modify the dosage of Sephience and/or dietary protein and Phe intake as needed to ensure adequate blood Phe level control. Frequent blood monitoring is recommended in the pediatric population.

Interaction with Levodopa: In a 10-year post-marketing safety surveillance program for a non-PKU indication using another drug that is a phenylalanine hydroxylase (PAH) activator, 3 patients with underlying neurological disorders experienced seizures, exacerbation of seizures, over-stimulation, and irritability during co-administration with levodopa. Monitor patients who are receiving levodopa for changes in neurological status during treatment with Sephience.

Adverse Reactions

Most common adverse reactions with Sephience (≥2% and > placebo) were diarrhea, headache, abdominal pain, hypophenylalaninemia, feces discoloration, and oropharyngeal pain.

Drug Interactions

Avoid concomitant use of drugs known to inhibit folate synthesis dihydrofolate reductase (DHFR) (e.g., trimethoprim, methotrexate, trimetrexate, pemetrexed, pralatrexate, raltitrexed, and piritrexim) while taking Sephience. Concomitant administration of such drugs may reduce sepiapterin metabolism to BH4. If concomitant use is not avoidable, monitor blood Phe levels.

Sephience and PDE-5 inhibitors (e.g., sildenafil, vardenafil, or tadalafil) induce vasorelaxation and may reduce blood pressure. Monitor for signs and symptoms of hypotension.

FDA Approves Gomekli (mirdametinib) for the Treatment of Adult and Pediatric Patients with NF1-PN

SpringWorks Therapeutics, Inc. (Nasdaq: SWTX), a commercial-stage biopharmaceutical company focused on severe rare diseases and cancer, announced  the U.S. Food and Drug Administration (FDA)   approval of  ™ (mirdametinib), SpringWorks’ MEK inhibitor, for the treatment of adult and pediatric patients 2 years of age and older with neurofibromatosis type 1 (NF1) who have symptomatic plexiform neurofibromas (PN) not amenable to complete resection.1 With the approval, SpringWorks was granted a rare pediatric disease priority review voucher (PRV) by the FDA.

“The NF1-PN patient community has a great need for more treatment options. With today’s approval, we are honored to serve both adults and children with NF1-PN and provide them with a therapy that has the potential to shrink their tumors and offer meaningful symptomatic relief,” said Saqib Islam, Chief Executive Officer of SpringWorks. “We are grateful to each clinical trial participant, their families, the investigators, and the patient advocacy groups involved in the journey towards making Gomekli available in the U.S. I am proud that we are delivering on our commitment to patients with devastating diseases with our company’s second FDA approval in less than 18 months.”

NF1 is a genetic disorder that currently affects approximately 100,000 children and adults in the United States.2,3 Patients with NF1 have approximately a 30-50% lifetime risk of developing plexiform neurofibromas, or PNs, which are tumors that grow in an infiltrative pattern along the peripheral nerve sheath and that can cause severe disfigurement, pain and functional impairment.2,4 There are approximately 40,000 people in the United States living with NF1-PN, the majority of whom are adults that have not had an approved medicine until Gomekli.5 Plexiform neurofibromas can transform into malignant peripheral nerve sheath tumors, an aggressive and potentially fatal disease.6 Surgical removal can be challenging due to the infiltrative tumor growth pattern of plexiform neurofibromas along nerves, and up to approximately 85% of plexiform neurofibromas are considered not amenable to complete resection.7,8,9

“Patients with NF1-PN often face significant challenges with their health and have had limited treatment options to manage this devastating condition,” said Christopher Moertel, M.D., Medical Director Pediatric Neuro-Oncology and Neurofibromatosis Programs and Kenneth and Betty Jayne Dahlberg Professor of Pediatrics, University of Minnesota, and lead investigator of the ReNeu trial. “It was very encouraging in the ReNeu trial to see that Gomekli provided deep and durable responses, with a manageable safety profile that enabled patients to stay on therapy. This approval represents an important advance, especially for adults who previously did not have an approved treatment.”

Gomekli was approved under Priority Review and SpringWorks received a rare pediatric disease priority review voucher from the FDA. Gomekli was previously granted Orphan Drug and Fast Track designations for the treatment of NF1-PN.

The FDA approval of Gomekli is based on results from the Phase 2b ReNeu trial, which enrolled 114 patients with NF1-PN ≥2 years of age (58 adults and 56 pediatric patients).10 Gomekli met the primary endpoint of confirmed objective response rate (ORR), as assessed by blinded independent central review, demonstrating a 41% ORR (N= 24/ 58) in adults and 52% in children (N=29/56).10 Tumor volume reductions were deep and durable; the median best percentage change in target PN volume was -41% (range: -90 to 13%) in adults and -42% (range: -91 to 48%) in children.10 Eighty-eight percent of adults and 90% of children with a confirmed response had a response of at least 12 months duration, and 50% and 48%, respectively, had a response of at least 24 months duration.10 Patients in both cohorts also experienced early and sustained significant improvements from baseline in pain, and quality of life, as assessed across multiple patient-reported outcome tools.10

Gomekli demonstrated a manageable safety and tolerability profile.1 The most common adverse events (>25%) reported in adults receiving Gomekli were rash, diarrhea, nausea, musculoskeletal pain, vomiting and fatigue.1 The most common adverse events (>25%) occurring in children were rash, diarrhea, musculoskeletal pain, abdominal pain, vomiting, headache, paronychia, left ventricular dysfunction, and nausea.1 Please see additional Important Safety Information below, including Warnings & Precautions relating to ocular toxicity, left ventricular dysfunction, dermatologic adverse reactions, and embryo-fetal toxicity.1

“We are excited to celebrate the extraordinary milestone of our partners and long-term friends at SpringWorks for the NF1-PN community. This FDA approval shows the power of collaboration to advance innovative science for drugs that may otherwise not have been taken forward,” said Annette Bakker, Ph.D., Chief Executive Officer of the Children’s Tumor Foundation. "When industry, researchers, and organizations like ours driving treatment innovation join forces, scientific progress moves faster, and patients gain access to the therapies they need. Every treatment approval is hard-won, built on research, persistence, and partnership. Today, that work delivers a critical new option for NF patients of all ages.”

“NF1-PN is a complex, devastating disease that affects not only individual patients, but entire families. Treatment advances are crucial to achieving better outcomes for patients and this FDA approval offers hope for NF patients and their families,” said Kim Bischoff, Executive Director, NF Network.

SpringWorks is dedicated to helping patients with NF1-PN access Gomekli and to providing support throughout their treatment journey. The SpringWorks CareConnections™ program is a comprehensive patient support program that offers personalized support services and resources to eligible Gomekli patients, including insurance coverage information and access support, financial assistance and personalized educational and emotional support. Physicians and patients can contact 1-844-CARES-55 (1-844-227-3755) or visit www.springworkstxcares.com for more information.

Gomekli is expected to be available through a specialty pharmacy and specialty distributor network in the United States within two weeks.

FDA Approves Gomekli (mirdametinib) for the Treatment of Adult and Pediatric Patients with NF1-PN

FDA Approves Journavx (suzetrigine), a First-in-Class Treatment for Adults With Moderate-to-Severe Acute Pain

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX)   announced   U.S. Food and Drug Administration (FDA)   approval of  Journavx (suzetrigine), an oral, non-opioid, highly selective NaV1.8 pain signal inhibitor for the treatment of adults with moderate-to-severe acute pain. Journavx is an effective, well-tolerated medicine without evidence of addictive potential indicated for use across all types of moderate-to-severe acute pain.

“Today’s approval is a historic milestone for the 80 million people in America who are prescribed a medicine for moderate-to-severe acute pain each year,” said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. “With the approval of Journavx, a non-opioid, pain signal inhibitor and the first new class of pain medicine approved in more than 20 years, we have the opportunity to change the paradigm of acute pain management and establish a new standard of care.”

“This is an incredible day for patients and physicians alike who now have an approved non-opioid treatment that delivers effective acute pain relief and a favorable safety profile without addictive potential,” said Jessica Oswald, M.D., M.P.H., Associate Physician in Emergency Medicine and Pain Medicine in San Diego and Vertex Acute Pain Steering Committee Member. “I believe Journavx could redefine the management of pain and become a foundational treatment option for people with all types of moderate-to-severe acute pain, where options aside from opioids have been so desperately needed.”

As part of Vertex’s ongoing commitment to patients, the company has established patient support programs to help ensure that qualified patients can access Journavx. For more information visit Journavx.com.

About Acute Pain

Acute pain is a serious and potentially disabling condition often caused by surgery, accident or injury. Over 80 million Americans are prescribed medicine to treat their moderate-to-severe acute pain every year. Of these, about 40 million are prescribed an opioid. Nearly 10% of acute pain patients treated initially with an opioid will go on to have prolonged opioid use, and about 85,000 patients will develop opioid use disorder annually. Poorly controlled acute pain can lead to reduced quality of life, development of chronic pain, and increased burden on the health care system and society.

About Journavx (suzetrigine)

Journavx (suzetrigine) is a first-in-class, oral, non-opioid, highly selective pain signal inhibitor that is selective for NaV1.8 relative to other NaV channels. NaV1.8 is a voltage-gated sodium channel that is selectively expressed in peripheral pain-sensing neurons (nociceptors), where its role is to transmit pain signals (action potentials). Because Journavx blocks pain signals only found in the periphery, not in the brain, Journavx provides effective relief of pain without the limitations of currently available therapies, including the addictive potential of opioids.

The U.S. Food and Drug Administration approved twice-daily Journavx for the treatment of adults with moderate-to-severe acute pain. Vertex has established a wholesale acquisition cost for Journavx in the United States of $15.50 per 50mg pill.

Vertex is also evaluating suzetrigine in peripheral neuropathic pain (PNP). The company’s Phase 3 pivotal program for suzetrigine in patients with painful diabetic peripheral neuropathy is ongoing, and Vertex plans to advance its pivotal program evaluating suzetrigine in patients with painful lumbosacral radiculopathy pending discussions with regulators.

INDICATION and IMPORTANT SAFETY INFORMATION

INDICATION AND USAGE

Journavx is a prescription medicine used to treat adults with moderate-to-severe short term (acute) pain.

It is not known if Journavx is safe and effective in children.

IMPORTANT SAFETY INFORMATION

Patients should not take Journavx if they take certain medicines that are strong inhibitors of an enzyme called CYP3A. Patients should ask their healthcare providers if they are not sure.

Before taking Journavx, patients should tell their healthcare provider about all of their medical conditions, including if they: have liver problems. People with liver problems may have an increased risk of getting side effects from taking Journavx; are pregnant or plan to become pregnant as it is not known if Journavx will harm an unborn baby. Patients and their healthcare providers should decide if they will take Journavx while they are pregnant, are breastfeeding, or are planning to breastfeed, as it is not known if Journavx passes into breast milk. Patients and their healthcare providers should decide if they will take Journavx while they are breastfeeding.

Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking Journavx with certain other medicines may affect the way Journavx and the other medicines work and may increase patients’ risk of side effects. Patients should ask their healthcare provider or pharmacist for a list of these medicines if they are not sure.

Patients should especially tell their healthcare provider if they take hormonal birth control medicine (contraceptives) containing progestins other than levonorgestrel or norethindrone. If they take one of these contraceptives (progestins other than levonorgestrel or norethindrone), they may not work as well during treatment with Journavx. Patients should also use nonhormonal contraceptives such as condoms or use other forms of hormonal birth control during treatment with Journavx and for 28 days after they stop taking Journavx. Medicines that are substrates of the CYP3A enzyme may become less effective during treatment with Journavx. Their healthcare provider may need to adjust the dose of patients’ medicine when starting or stopping Journavx. Patients should know the medicines they take and keep a list of them to show their healthcare provider and pharmacist when they get a new medicine. Patients should not take food or drink containing grapefruit while taking Journavx.

Journavx can cause side effects: The most common side effects for patients treated with Journavx include itching, muscle spasms, increased blood level of creatine phosphokinase, and rash. Journavx may temporarily reduce the chance of females becoming pregnant while on treatment. Patients should talk to their healthcare provider if they have concerns about becoming pregnant. If patients are using contraceptives, continue to use contraceptives during treatment with Journavx. Patients should tell their healthcare provider if they have any side effect that bothers them or that does not go away. These are not all of the possible side effects of Journavx. Patients should call their healthcare provider for medical advice about side effects. Patients may report side effects to the FDA at 1-800-FDA-1088.

FDA Approves Palsonify (paltusotine) for the Treatment of Acromegaly in Adults

Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced that the U.S. Food and Drug Administration (FDA) approved Palsonify (paltusotine) for the first-line treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option. Palsonify, a selectively-targeted somatostatin receptor type 2 nonpeptide (SST2) agonist, is now the first once-daily, oral treatment approved for adults with acromegaly.

“With the FDA approval of our lead therapy Palsonify, today marks a new era for those living with acromegaly and also for Crinetics as a company,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “We are very pleased to be fulfilling our commitment to transforming patient lives. This approval is the first to come from our deep pipeline of first-in-class, small molecule drugs. This would not be possible without the help and partnership of people living with acromegaly, their caretakers, our employees, and the clinical researchers and health care professionals who contributed to Palsonify’s successful development program. Thank you to all involved.”

The approval is based on data from the PATHFNDR-1 and PATHFNDR-2 Phase 3 pivotal trials, which evaluated Palsonify’s safety and efficacy in previously treated and medically untreated adults with acromegaly. Across both trials, Palsonify consistently demonstrated rapid onset, reliable biochemical control, and sustained efficacy.

Participants also reported significant reductions in signs and symptoms associated with acromegaly as measured by the Acromegaly Symptom Diary (ASD) — an FDA-aligned patient-reported outcome tool developed to capture the symptoms that matter to people living with acromegaly. Symptoms include headaches, joint pain, sweating, fatigue, weakness, swelling, and/or numbness/tingling. Palsonify was generally well-tolerated, with no serious adverse events reported in the randomized controlled portion of the trial.

Long-term results from the open-label extension (OLE) phases of both trials were presented at this year’s Endocrine Society’s annual meeting, ENDO 2025, providing further evidence of Palsonify’s ability to deliver durable IGF-1 control, sustained improvements in patient symptom burden, and a consistent safety profile. Ninety-one percent of patients from PATHFNDR-1 and 97 percent of completers from PATHFNDR-2 enrolled in the OLE.

“The PATHFNDR clinical development program set a new standard for acromegaly treatment by demonstrating the ability of Palsonify to drive both biochemical and symptom control, regardless of the degree of underlying disease severity,” said Dr. Shlomo Melmed, Executive Vice President of Medicine and Health Sciences and Dean of the Medical Faculty at Cedars-Sinai, “The approval of Palsonify is a significant advancement for our patients, as there is an unmet need for an easy-to-administer and safe therapeutic option with a rapid action and durable response that can consistently manage acromegaly.”

“For people living with acromegaly, treatment once meant burdensome injections, breakthrough symptoms, and lifestyle sacrifices just to stay on track,” said Jill Sisco, President of Acromegaly Community. “What matters most to our community – maintaining consistent control so the disease doesn’t control us – led us to partner with the FDA on Externally Led Patient-Focused Drug Development meetings. This new treatment reflects that our voices have been heard in shaping the next generation of acromegaly care.”

Palsonify is expected to be available in the U.S. in early October. Crinetics is ensuring broad access to Palsonify by working closely with payers, healthcare providers, and patient advocacy organizations to support those who may benefit from this treatment.

As part of this commitment, Crinetics has launched CrinetiCARE®, a comprehensive support program designed to assist people living with acromegaly throughout their treatment journey. CrinetiCARE provides disease and product education, benefit verification, financial assistance resources, and access to dedicated nurse educators who can offer support with treatment onboarding and ongoing adherence.

A Marketing Authorization Application (MAA) for paltusotine in acromegaly is currently under review for use in the European Union, and the current timeline for the Committee for Medicinal Products and Human Use (CHMP) opinion is the first half of 2026. Crinetics is in partnership with Sanwa Kagaku Kenkyuso (SKK) to develop and commercialize paltusotine for acromegaly in Japan.

Paltusotine is also being evaluated for the treatment of carcinoid syndrome in the pivotal Phase 3 CAREFNDR trial. Global enrollment for CAREFNDR is expected throughout 2025.

Palsonify (paltusotine) INDICATION:

Palsonify is a somatostatin receptor agonist indicated for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS:

Cholelithiasis and Its Complications: Cholelithiasis, including related complications such as acute cholecystitis and pancreatitis, have been reported. Monitor patients periodically. Discontinue Palsonify if complications of cholelithiasis occur and treat appropriately.

Hyperglycemia and Hypoglycemia: Hyperglycemia, diabetes mellitus, or hypoglycemia, may occur. Monitor blood glucose levels when Palsonify treatment is initiated or when dosage is altered. Adjust antidiabetic treatment accordingly.

Cardiovascular Abnormalities: Cardiac conduction abnormalities and other ECG changes such as PR interval prolongation, bradycardia, sinus arrest, and atrioventricular block may occur in patients with acromegaly and were reported in Palsonify clinical trials. Dosage adjustments of concomitant drugs that have bradycardic effects may be necessary.

ADVERSE REACTIONS:

Most common adverse reactions (>5%) are diarrhea, abdominal pain, nausea, decreased appetite, sinus bradycardia, hyperglycemia, palpitations, and gastroenteritis.

FDA Approves Palsonify (paltusotine) for the Treatment of Acromegaly in Adults

FDA Approves Harliku (nitisinone) for the Treatment of Patients with Alkaptonuria

In continuation of my update on nitisinone

Cycle Pharmaceuticals has announced   the FDA approval of  Harliku (nitisinone) Tablets for the reduction of urine homogentisic acid (HGA) in adult patients with AKU.1

Launching in July 2025, Harliku will be the first and only FDA-approved treatment for AKU,1 an ultra-rare genetic metabolic disorder in which patients have a buildup of HGA that leads to osteoarthritis, ochronosis, and complications in the kidneys, and heart.2 Patients with AKU often develop pain, reduced joint mobility, and require large joint replacements; the symptoms impede their physical functionality, emotional well-being, and quality of life.2,3

The approval of Harliku is based on data from a randomized, no-treatment controlled study of 40 patients with AKU. As part of the intramural research program of the National Human Genome Research Institute at the National Institutes of Health (NIH), Dr. Wendy J. Introne, MD and her team showed that nitisinone helped patients improve pain, energy levels, and physical functioning after three years of treatment, assessed using the 36-Item Short-Form Survey.4

Steve Fuller, Chief Strategy Officer of Cycle Pharmaceuticals commented,

“We are deeply grateful for Cycle’s collaboration with Dr. Wendy Introne, Dr. Bill Gahl, and the broader team at the NIH, whose pioneering work laid the foundation for this FDA approval. We look forward to making Harliku available to U.S. AKU patients as soon as possible and remain committed to supporting the AKU community to the fullest extent of our capabilities.”

“The approval of Harliku is an important advance for the AKU community. Our scientific team has translated decades of research into launching nitisinone as a new treatment option, and we stand hopeful that it can ease the significant burden of AKU,” said Dr. Wendy J. Introne, MD, of NIH’s National Human Genome Research Institute (NHGRI).

Building on the company’s previous success in rare diseases, Harliku will be Cycle Pharmaceuticals’ eighth commercial product in the US.

Indications

Harliku™ is indicated for the reduction of urine homogentisic acid (HGA) in adult patients with alkaptonuria (AKU).

Important Safety Information

Do not prescribe Harliku to patients allergic to nitisinone or any other contained ingredients.

Warnings and Precautions:

Ocular Symptoms and Hyperkeratotic Plaques Due to Elevated Plasma Tyrosine Level:

Ocular signs and symptoms including keratitis, corneal opacities, corneal irritation, corneal ulcers, conjunctivitis, eye pain, and photophobia, have been reported in patients.

Perform slit-lamp examination prior to treatment and regularly thereafter. Reexamine patients if symptoms develop or tyrosine levels are > 500 micromole/L. Assess plasma tyrosine levels in patients with an abrupt change in neurological status.

Perform a clinical laboratory assessment, including plasma tyrosine levels, in patients with an abrupt change in neurological status.

Leukopenia and Severe Thrombocytopenia

In clinical trials, patients with hereditary tyrosinemia type 1 (HT-1) treated with another oral formulation of nitisinone and dietary restriction, developed reversible leukopenia, thrombocytopenia, or both. No patients developed infections or bleeding as a result of the episodes of leukopenia and thrombocytopenia. Monitor platelet and white blood cell counts during Harliku therapy.

Adverse Reactions:

The most common adverse reactions (≥1%) reported in patients with AKU taking nitisinone in clinical trials are elevated tyrosine levels, thrombocytopenia and keratitis.

Drug Interactions:

Nitisinone is a moderate CYP2C9 inhibitor and a weak CYP2E1 inducer. Potential clinical impact of Harliku administration with CYP2C9 substrates. Reduce the dosage of the co-administered drugs metabolized by CYP2C9 by half. Additional dosage adjustments may be needed.

Nitisinone is an inhibitor of OAT1/OAT3. Potential clinical impact of administration with OAT1/OAT3 substrates. Patients should be monitored for p

FDA Approves Harliku (nitisinone) for the Treatment of Patients with Alkaptonuria

FDA Approves Ekterly (sebetralstat) the First and Only Oral On-demand Treatment for Hereditary Angioedema (HAE)

KalVista Pharmaceuticals, Inc.  announced  the U.S. Food and Drug Administration (FDA) approval of Ekterly (sebetralstat), a novel plasma kallikrein inhibitor, for the treatment of acute attacks of hereditary angioedema (HAE) in adult and pediatric patients aged 12 years and older. Ekterly is the first and only oral on-demand treatment for HAE.

“The FDA approval of Ekterly is a defining moment for people living with HAE,” said Ben Palleiko, CEO of KalVista. “Ekterly enables people to treat attacks the moment symptoms begin, wherever they are. This approval affirms the strength of our science and deep commitment to the HAE community. I am profoundly grateful to the KalVista team for their dedication and perseverance, and to the patients and healthcare providers, as well as the HAEA and HAEi, for making this possible. Ekterly has the potential to become the foundational treatment for HAE, and our focus now is on delivering it to the people who need it.”

“As the first orally administered on-demand therapy for HAE attacks, Ekterly provides patients and physicians with an important and welcome advance in HAE treatment options,” said Anthony J. Castaldo, chief executive officer of the U.S. Hereditary Angioedema Association.

Prior to Ekterly’s approval, all on-demand HAE treatment options approved in the U.S. required intravenous or subcutaneous administration, which carries a significant treatment burden.1 Even with the use of long-term prophylaxis as a preventative therapy, most people living with HAE continue to have unpredictable attacks and require ready access to on-demand medication.1

“This is an important moment for patients, giving people living with HAE a treatment option that could provide greater independence and control over managing their condition,” said Marc A. Riedl, MD, Professor of Medicine and Clinical Director, U.S. Hereditary Angioedema Association Center at the University of California, San Diego, and an investigator for the KONFIDENT phase 3 trial. "Until now, on-demand treatment relied on injectable subcutaneous or intravenous administration, often resulting in delayed intervention. Having an oral option empowers patients to treat attacks early, which aligns with treatment guidelines and advances our goal as physicians to reduce the overall burden of disease.”

The efficacy and safety of Ekterly was established by the results from KalVista’s phase 3 KONFIDENT clinical trial, which was the largest clinical trial program ever conducted in HAE. Data from KONFIDENT was published in the New England Journal of Medicine in May 2024, showing that Ekterly achieved significantly faster symptom relief, reduction in attack severity, and attack resolution than placebo, and was well-tolerated with a safety profile similar to placebo.2 The trial randomized 136 HAE patients from 66 clinical sites across 20 countries. These results were further supported by the more real-world KONFIDENT-S open-label extension trial, which as of September 2024, showed that EKTERLY enabled patients to treat attacks in a median of 10 minutes following onset. The most recent data from KONFIDENT-S shows that beginning of symptom relief occurred in a median of 1.3 hours among attacks involving the larynx, the abdomen, and for breakthrough attacks among patients receiving long-term prophylaxis. The safety profile of EKTERLY 600 mg in KONFIDENT-S, in a much larger number of attacks (>1700), was consistent with that observed in KONFIDENT.

KalVista will launch Ekterly in the U.S. immediately, and physicians can begin writing prescriptions today. As part of the Company’s commitment to supporting patients, KalVista has established KalVista Cares™, a comprehensive patient support program that offers personalized services and resources for eligible individuals. This includes assistance with navigating insurance coverage, access support, and ongoing help throughout the treatment journey.
