FDA Approves Opzelura (ruxolitinib) Cream for the Treatment of Atopic Dermatitis (AD)

In continuation of my update on Opzelura (ruxolitinib)  , Incyte (Nasdaq:INCY)announced  the U.S. Food and Drug Administration (FDA)  approval Opzelura™ (ruxolitinib) cream for the short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies, or when those therapies are not advisable. Opzelura is the first and only topical formulation of a JAK inhibitor approved in the United States. Research shows dysregulation of the JAK-STAT pathway contributes to key features of AD such as itch, inflammation and skin barrier dysfunction.

“Atopic dermatitis is a chronic immune-mediated disease that can be challenging to manage. Many patients do not respond well to existing treatments and have uncontrolled disease,” said Jonathan Silverberg, M.D., Ph.D., M.P.H., Associate Professor of Dermatology and Director of Clinical Research and Contact Dermatitis at The George Washington University School of Medicine and Health Sciences. “As a clinician, I am excited to have a non-steroidal topical cream like Opzelura.”

“The approval of Opzelura is an important advancement in the treatment of AD, and we are pleased to offer a novel topical treatment option that targets a pathway believed to be a source of inflammation,” said Hervé Hoppenot, Chief Executive Officer, Incyte. “At Incyte, we are committed to transforming the treatment of immune-mediated dermatologic conditions like AD. We look forward to bringing Opzelura to the patient community and also continuing to explore its potential in other challenging skin diseases.”

The FDA approval was based on data from the TRuE-AD (Topical Ruxolitinib Evaluation in Atopic Dermatitis) clinical trial program, consisting of two randomized, double-blind, vehicle-controlled Phase 3 studies (TRuE-AD1 and TRuE-AD 2) evaluating the safety and efficacy of Opzelura in more than 1,200 adolescents and adults with mild to moderate AD. Results from the studies showed patients experienced significantly clearer skin and itch reduction when treated with Opzelura cream 1.5% twice daily (BID), compared to vehicle (non-medicated cream):

• Significantly more patients treated with Opzelura achieved Investigator’s Global Assessment (IGA) Treatment Success (IGA-TS, primary endpoint) at Week 8 (defined as an IGA score of 0 [clear] or 1 [almost clear] with at least a 2-point improvement from baseline): 53.8% in TRuE-AD1 and 51.3% in TRuE-AD2, compared to vehicle (15.1% in TRuE-AD1, 7.6% in TRuE-AD2; P<0.0001).
• Significantly more patients treated with Opzelura experienced a clinically meaningful reduction in itch from baseline at Week 8, as measured by a ≥4-point reduction in the itch Numerical Rating Scale (itch NRS4): 52.2% in TRuE-AD1 and 50.7% in TRuE-AD2, compared to vehicle (15.4% in TRuE-AD1, 16.3% in TRuE-AD2; P<0.0001), among patients with an NRS score of at least 4 at baseline.

In clinical trials, the most common (≥1%) treatment-emergent adverse reactions in patients treated with Opzelura were nasopharyngitis, diarrhea, bronchitis, ear infection, eosinophil count increased, urticaria, folliculitis, tonsillitis and rhinorrhea2. See Important Safety Information below, including Boxed Warnings for serious infections, mortality, malignancy, major adverse cardiovascular events and thrombosis, seen with JAK inhibitors for inflammatory conditions.

“It can be hard for people to fully appreciate how difficult AD can be and the tremendous impact it has on patients,” said Julie Block, President & CEO, National Eczema Association. “The chronic itch is difficult to cope with and related sleep issues can be exhausting. Many patients and their dermatologists are looking for additional options to meet current unmet needs in the management of AD. The approval of Opzelura is exciting news, and we welcome a new treatment option for our community.”

AD is a chronic skin disease affecting more than 21 million people aged 12 years and older in the U.S. and is characterized by inflammation and itch3. Signs and symptoms include irritated and itchy skin that can cause red lesions that may ooze and crust. People with AD are also more susceptible to bacterial, viral and fungal infections.

FDA Approves Exkivity (mobocertinib) for EGFR Exon20 Insertion+ Non-Small Cell Lung Cancer (NSCLC)

Takeda Pharmaceutical Company Limited  announced   the U.S. Food and Drug Administration (FDA)  approval of  Exkivity (mobocertinib) for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy. Exkivity, which was granted priority review and received Breakthrough Therapy Designation, Fast Track Designation and Orphan Drug Designation from the FDA, is the first and only approved oral therapy specifically designed to target EGFR Exon20 insertion mutations. This indication is approved under Accelerated Approval based on overall response rate (ORR) and DoR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

“The approval of Exkivity introduces a new and effective treatment option for patients with EGFR Exon20 insertion+ NSCLC, fulfilling an urgent need for this difficult-to-treat cancer,” said Teresa Bitetti, president, Global Oncology Business Unit, Takeda. “Exkivity is the first and only oral therapy specifically designed to target EGFR Exon20 insertions, and we are particularly encouraged by the duration of the responses observed with a median of approximately 1.5 years. This approval milestone reinforces our commitment to meeting the needs of underserved patient populations within the oncology community.”

The FDA simultaneously approved Thermo Fisher Scientific’s Oncomine Dx Target Test as an NGS companion diagnostic for Exkivity to identify NSCLC patients with EGFR Exon20 insertions. NGS testing is critical for these patients, as it can enable more accurate diagnoses compared to polymerase chain reaction (PCR) testing, which detects less than 50% of EGFR Exon20 insertions.

“EGFR Exon20 insertion+ NSCLC is an underserved cancer that we have been unable to target effectively with traditional EGFR TKIs,” said Pasi A. Jänne, MD, PhD, Dana Farber Cancer Institute. “The approval of Exkivity (mobocertinib) marks another important step forward that provides physicians and their patients with a new targeted oral therapy specifically designed for this patient population that has shown clinically meaningful and sustained responses.”

“Patients with EGFR Exon20 insertion+ NSCLC have historically faced a unique set of challenges living with a very rare lung cancer that is not only underdiagnosed, but also lacking targeted treatment options that can improve response rates,” said Marcia Horn, executive director, Exon 20 Group at ICAN, International Cancer Advocacy Network. “As a patient advocate working with EGFR Exon20 insertion+ NSCLC patients and their families every day for nearly five years, I am thrilled to witness continued progress in the fight against this devastating disease and am grateful for the patients, families, healthcare professionals and scientists across the globe who contributed to the approval of this promising targeted therapy.”

The FDA approval is based on results from the platinum-pretreated population in the Phase 1/2 trial of Exkivity, which consisted of 114 patients with EGFR Exon20 insertion+ NSCLC who received prior platinum-based therapy and were treated at the 160 mg dose. Results were presented at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting from the Phase 1/2 trial and demonstrated a confirmed ORR of 28% per independent review committee (IRC) (35% per investigator) as well as a median DoR of 17.5 months per IRC, a median overall survival (OS) of 24 months and a median progression-free survival (PFS) of 7.3 months per IRC.

FDA Approves Trudhesa (dihydroergotamine mesylate) Nasal Spray for the Acute Treatment of Migraine

Impel NeuroPharma, Inc. (NASDAQ: IMPL),  announced  the U.S. Food and Drug Administration (FDA) approval of  Trudhesa™ (dihydroergotamine mesylate) nasal spray (0.725 mg per spray) for the acute treatment of migraine with or without aura in adults. Trudhesa was previously known as INP104.

Using Impel’s proprietary Precision Olfactory Delivery (POD®) technology, Trudhesa gently delivers dihydroergotamine mesylate (DHE)—a proven, well-established therapeutic—quickly to the bloodstream through the vascular-rich upper nasal space.  Trudhesa bypasses the gut and potential absorption issues, offering rapid, sustained, and consistent symptom relief without injection or infusion, even when administered hours after the onset of a migraine attack.  The Commercial launch of Trudhesa is planned for early October 2021.

“We are delighted with the approval of Trudhesa and are proud to offer the millions of Americans with migraine a non-oral, acute treatment option that may provide rapid, sustained, and consistent relief, even when taken late into a migraine attack,” said Adrian Adams, Chairman and Chief Executive Officer of Impel NeuroPharma. “The approval of Trudhesa marks the culmination of more than a decade of research and advanced engineering to pair the proven efficacy of DHE with our innovative POD technology. We are grateful for all the patients and investigators who participated in our clinical trials and who were instrumental in bringing this needed advancement to the migraine community.”

The New Drug Application for Trudhesa included the results of the Phase 3, open-label, pivotal safety study, STOP 301, which is the largest longitudinal study ever conducted with DHE using nasal spray delivery.  More than 5,650 migraine attacks were treated over 24 or 52 weeks during the study. The primary objective of the study was to assess the safety and tolerability of Trudhesa. Exploratory objectives included efficacy assessments of migraine measures and a patient acceptability questionnaire. In the trial, Trudhesa was generally well tolerated and exploratory efficacy findings showed it provided rapid, sustained, and consistent symptom relief. Unlike some oral acute treatments that need to be taken within one hour of attack onset to be most effective, STOP 301 reported Trudhesa offered consistent efficacy even when taken late into a migraine attack. 

“Many of my patients need more from their migraine treatment, and Trudhesa offers a non-oral, fast-acting, reliable option that overcomes many current medication challenges,” said Stephanie J. Nahas-Geiger, MD, MSEd, Associate Professor in the Department of Neurology, and Program Director of the Headache Medicine Fellowship Program, Thomas Jefferson University. “Its upper nasal delivery circumvents the GI tract and common phenomena associated with migraine, such as nausea and gastroparesis, that can impact the effectiveness of oral treatments. And, importantly, it is a self-administered, single dose that can be taken anytime during a migraine attack, so patients don’t need to worry about missing the opportunity to benefit from using Trudhesa within a certain timeframe. I think patients will be very receptive to this treatment, because it pairs the long-proven benefits of DHE with a patient-friendly delivery system.”

There were no serious Trudhesa-related treatment-emergent adverse events (TEAEs) observed in the STOP 301 study and the majority of TEAEs were mild and transient in nature.  Some of the most frequently reported Trudhesa-related TEAEs (≥2%) during the entire 52-week study period were nasal congestion (17.8%), nausea (6.8%), nasal discomfort (6.8%), abnormal olfactory test (6.8%) and vomiting (2.7%).

In the STOP 301 study, patient-reported exploratory efficacy findings reported that more than a third of patients (38%) had pain freedom,  two-thirds (66%) had pain relief,  and more than half (52%) had freedom from their most bothersome migraine symptom  at two hours after their first dose of Trudhesa. For one in six patients (16%), pain relief started as early as 15 minutes.  Of patients who were pain free at two hours, 93 percent were still pain free at 24 hours,11 and 86 percent were still pain free through two days.  The great majority of patients (84%) reported that Trudhesa was easy to use  and preferred it over their current therapy.

“Migraine is a disease that impacts the whole body and is the second leading cause of disability,”  said Kevin Lenaburg, executive director, Coalition for Headache and Migraine Patients (CHAMP), which represents 12 national headache and migraine patient advocacy groups. “Historically there have not been enough effective treatments for treating migraine attacks, especially treatments that are not oral medicines, which can be challenging due to nausea, vomiting and other GI symptoms that can occur during a migraine. We welcome an important new treatment that combines the long-established efficacy of DHE with a non-oral, innovative delivery system that allows patients to self-administer wherever they are and at any point within a migraine attack.”

Invega Hafyera (paliperidone palmitate) Extended-Release Injectable Suspension for schizophrenia

In continuation of my update on paliperidone palmitate

The Janssen Pharmaceutical Companies of Johnson & Johnson announced the U.S. Food and Drug Administration (FDA)   approval of  long-acting atypical antipsychotic Invega Hafyera (6-month paliperidone palmitate), the first-and-only twice-yearly injectable for the treatment of schizophrenia in adults. Before transitioning to Invega Hafyera, patients must be adequately treated with Invega Sustenna (1-month paliperidone palmitate) for at least four months, or Invega Trinza (3-month paliperidone palmitate) for at least one 3-month injection cycle. 

The FDA approval of Invega Hafyera is based on the results of a 12-month, randomized, double-blind, non-inferiority Phase 3 global study that enrolled 702 adults (ages 18-70) living with schizophrenia from 20 countries. The results showed non-inferiority of Invega Hafyera compared to Invega Trinza on the primary endpoint of time to first relapse at the end of the 12-month period. Results found that 92.5 percent of patients treated with Invega Hafyera and 95 percent treated with Invega Trinza were relapse-free at 12 months.1 Relapse was defined as psychiatric hospitalization, increase in Positive and Negative Syndrome Scale [PANSS] total score, increase in individual PANSS item scores, self-injury, violent behavior, or suicidal/homicidal ideation.

The safety profile observed in the trial was consistent with previous studies of Invega Sustenna and Invega Trinza with no new safety signals emerging.1 The most common adverse reactions (≥5%) in the Invega Hafyera clinical trial were upper respiratory tract infection (12%), injection site reaction (11%), weight increase (9%), headache (7%), and parkinsonism (5%).

“Before I found the right treatment plan for me, my symptoms often got in the way of things that I loved to do,” said Patrick, an adult living with schizophrenia and a participant in the clinical trial. “But since my doctor introduced me to Janssen’s long-acting injectable options and my symptoms are controlled, I have the clarity to focus on the present, but also the stability to plan for my future.”

Schizophrenia is a complex and chronic brain disorder in which the symptoms and potential for relapse (or recurrence of symptoms) can impact many aspects of a person’s daily life. On average, an adult with schizophrenia experiences nine relapses in less than six years, often due to missed doses of medication. Adults living with schizophrenia and their loved ones face ongoing functional, emotional, and financial burdens. In addition, patients who experience more relapses may have more hospitalizations, which can lead to higher medical costs for patients, hospital systems, and payers.

“For too long, we’ve accepted relapse as a normal part of living with schizophrenia, while research continues to demonstrate that stronger medication adherence means better patient outcomes,” said Gustavo Alva*, M.D., DFAPA, Medical Director at ATP Clinical Research and 6-month paliperidone palmitate clinical trial investigator. “The Phase 3 trial results provide compelling evidence that 6-month paliperidone palmitate offers longer-term symptom control with the fewest doses per year, which may support greater patient adherence.”

Recently, the National Council for Mental Wellbeing and the American Psychiatric Association updated their schizophrenia treatment guidance and guidelines to expand the recommended use of long-acting injectables for appropriate adult patients living with schizophrenia.

Invega Hafyera is a long-acting injectable treatment that is administered by a healthcare provider in the upper buttocks area every six months. Invega Hafyera dissolves slowly into the bloodstream after injection, resulting in continuous treatment and symptom control over six months.

FDA Approves Welireg (belzutifan) for the Treatment of Patients With Certain Types of Von Hippel-Lindau (VHL) Disease-Associated Tumors

Merck (NYSE: MRK),  announced that the U.S. Food and Drug Administration (FDA) has approved 'Welireg, an oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor, for the treatment of adult patients with von Hippel-Lindau (VHL) disease who require therapy for associated renal cell carcinoma (RCC), central nervous system (CNS) hemangioblastomas, or pancreatic neuroendocrine tumors (pNET), not requiring immediate surgery. The recommended dose of Welireg (40 mg tablets) is 120 mg once daily until disease progression or unacceptance toxicity. The approval is based on results from the open-label Study 004 trial (N=61), where the major efficacy endpoint was overall response rate (ORR) in patients with VHL-associated RCC.

Welireg is the first HIF-2α inhibitor therapy approved in the U.S. As an inhibitor of HIF-2α, Welireg reduces transcription and expression of HIF-2α target genes associated with cellular proliferation, angiogenesis and tumor growth.

The Welireg label contains a boxed warning that exposure to Welireg during pregnancy can cause embryo-fetal harm. Verify pregnancy status prior to the initiation of Welireg. Advise patients of these risks and the need for effective non-hormonal contraception. Welireg can render some hormonal contraceptives ineffective. Welireg can cause severe anemia that can require a blood transfusion. Monitor for anemia before initiation of Welireg and periodically throughout treatment. Welireg can cause severe hypoxia that may require discontinuation, supplemental oxygen, or hospitalization. Monitor oxygen saturation before initiation of and periodically throughout treatment with Welireg. For more information, see "Selected Safety Information" below.

“VHL disease is a rare and serious condition. Until today, there were no systemic therapies approved to help treat patients diagnosed with certain types of VHL-associated tumors,” said Dr. Eric Jonasch, principal investigator of Study 004 and professor, Department of Genitourinary Medical Oncology, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center. “The approval of Welireg, which is based on data showing an overall response rate across three different types of VHL-associated tumors, addresses this significant unmet need by introducing a new option for physicians and their patients impacted by this disease.”

“Welireg is the first and only approved systemic therapy for patients with certain types of VHL-associated tumors, representing an important new treatment option for patients affected by this rare condition,” said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. “Today’s approval of Welireg is a significant milestone and is a testament to Merck’s commitment to bring forward innovative new treatment options for more patients.”

“The approval of a non-surgical treatment option is meaningful for helping patients with certain types of VHL-associated tumors,” said Dr. Ramaprasad Srinivasan, head, Molecular Cancer Therapeutics Section, Urologic Oncology Branch, National Cancer Institute (NCI), and principal investigator on the Cooperative Research and Development Agreement (CRADA) under which the NCI served as a site in Study 004. “In Study 004, nearly half of all patients with VHL-associated renal cell carcinoma, as well as the majority of patients with VHL-associated central nervous system hemangioblastomas or pancreatic neuroendocrine tumors, who were treated with Welireg experienced a reduction of their respective tumor size. The FDA’s approval of Welireg marks an important step forward by introducing a systemic therapy that has the potential to improve the current treatment paradigm for patients with certain types of VHL-associated tumors.”

FDA Approves Voxzogo (vosoritide) to Increase Linear Growth in Children with Achondroplasia

 

BioMarin Pharmaceutical Inc. (NASDAQ: BMRN)  announced  the U.S. Food and Drug Administration (FDA)  approval of VOXZOGO™ (vosoritide) for Injection, indicated to increase linear growth in pediatric patients with achondroplasia five years of age and older with open epiphyses (growth plates). This indication is approved under accelerated approval based on an improvement in annualized growth velocity (AGV). Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory studies. To fulfill this post-marketing requirement, BioMarin intends to use the ongoing open-label extension studies compared to available natural history.

Voxzogo is the first FDA approved treatment for children with achondroplasia. In patients with achondroplasia, endochondral bone growth, an essential process by which bone tissue is created, is negatively regulated due to a gain of function mutation in fibroblast growth factor receptor 3 gene (FGFR3). Voxzogo, a C-type natriuretic peptide (CNP) analog, represents a new class of therapy, which acts as a positive regulator of the signaling pathway downstream of FGFR3 to promote endochondral bone growth.

"Voxzogo is a medical first that is rooted in BioMarin's focus on molecular genetics and targets the underlying cause of the condition. More than a decade of scientific research underpins the medical advance that Voxzogo represents. We thank the FDA for recognizing its value as the first therapeutic treatment option for children with achondroplasia," said Jean-Jacques Bienaimé, Chairman and Chief Executive Officer of BioMarin. "We extend our gratitude to the community, clinical investigators and the children and their families, who participated and continue to participate in our comprehensive clinical research program as we continue to investigate the full potential of vosoritide."

"Achondroplasia is a lifelong genetic condition resulting from the disordered skeletal architecture caused by impaired endochondral bone growth throughout childhood," said Lynda Polgreen, M.D., an investigator in clinical trials for Voxzogo and an Investigator at The Lundquist Institute at Harbor-UCLA Associate Professor at David Geffen School of Medicine – UCLA. "This approval is an important milestone representing the first time that physicians will be able to offer a therapy targeted at the root cause of the condition for families of children with achondroplasia aged five and older."

"We applaud the FDA for recognizing the urgent unmet medical need for this progressive condition. As a parent of a child with achondroplasia, I see the availability of treatments that impact bone growth as an important step forward," said Amer Haider Co-Founder of Growing Stronger, an organization with a mission to improve the quality of medical care for little people through supporting research. The organization raises nonprofit donations that are granted to researchers focused on dwarfism.

Mr. Haider added, "BioMarin continues to support the achondroplasia community and has a long track record of advancing the standard of care in rare genetic conditions."

With this approval, the FDA also issued a Rare Pediatric Disease Priority Review Voucher (PRV), which confers priority review to a subsequent drug application that would not otherwise qualify for priority review. The rare pediatric disease PRV program is designed to encourage development of new drugs and biologics for the prevention or treatment of rare pediatric diseases.

The approval was based on the outcomes of a global randomized, double-blind, placebo-controlled Phase 3 study evaluating the efficacy and safety of Voxzogo and the open-label extension of this Phase 3 study. The study enrolled 121 children aged 5 to 14.9 with achondroplasia. Baseline mean AGV in the placebo and Voxzogo groups was 4.06 cm/year and 4.26 cm/year, respectively. At week 52, the change from baseline in AGV was -0.17 cm/year for the placebo treated patients and 1.40 cm/year for the Voxzogo treated patients, resulting in a statistically significant improvement in AGV of 1.57 cm/year in favor of Voxzogo. After the 52 week double blind, placebo–controlled, phase 3 study, 58 subjects initially randomized to Voxzogo enrolled into an open–label extension. Among the subjects who had two years of follow–up since randomization, the improvement in AGV was maintained.

FDA Approves Vuity (pilocarpine HCI ophthalmic solution) to Treat Presbyopia (Age-Related Blurry Near Vision)....

Allergan, an AbbVie (NYSE: ABBV) company,   announced the U.S. Food and Drug Administration (FDA) approval of Vuity (pilocarpine HCl ophthalmic solution) 1.25% for the treatment of presbyopia, commonly known as age-related blurry near vision, in adults. Vuity is the first and only FDA-approved eye drop to treat this common and progressive eye condition that affects 128 million Americans, nearly half of the U.S. adult population.

"Most adults cope with presbyopia, or difficulty with near vision, as we age. Beginning around the age of 40, many find themselves using reading glasses, holding text further away, or even increasing the font size and lighting on screens to try to see more clearly," said Michael Severino, M.D., vice chairman and president, AbbVie. "We are proud to offer Vuity as a first-of-its-kind once-daily eye drop that we believe will change the way people and their eye doctors approach presbyopia. The FDA approval of Vuity exemplifies our continued pursuit of innovative new treatments that push the boundaries of what's possible in eye care."

Vuity is a daily, prescription eye drop that works in as early as 15 minutes and lasts up to 6 hours, as measured on day 30, to improve near and intermediate vision without impacting distance vision. Specifically designed for presbyopia, Vuity is an optimized formulation of pilocarpine, an established eye care therapeutic, delivered with pHast™ technology. The proprietary pHast™ technology allows Vuity to rapidly adjust to the physiologic pH of the tear film. Vuity uses the eye's own ability to reduce pupil size, improving near vision without affecting distance vision.

"As we age, the lenses of our eyes become less flexible, making it more difficult to focus on things up close. Vuity offers a novel, safe, well-tolerated and effective alternative to current options for managing age-related blurry near vision," said George O. Waring IV, M.D., FACS, medical director, Waring Vision Institute, South Carolina, and GEMINI 1 and GEMINI 2 principal study investigator. "I am particularly encouraged by the rapid onset of action and duration of efficacy for Vuity to improve near and intermediate vision without impacting distance vision with one drop daily, particularly for those with mild to moderate presbyopia."  

The FDA approval of Vuity is based on data from two pivotal phase 3 clinical studies, GEMINI 1 and GEMINI 2, which evaluated the efficacy, safety and tolerability of Vuity for the treatment of presbyopia. In both studies, Vuity met the primary endpoint, reaching statistical significance in improvement in near vision in low light (mesopic) conditions without a loss of distance vision versus the vehicle (placebo) on day 30 at hour 3. Additionally, improvement was seen as early as 15 minutes and lasted through 6 hours. There were no serious adverse events observed in participants receiving VUITY in either the GEMINI 1 or GEMINI 2 study. The most common adverse events occurring at a frequency of >5% were headache and eye redness.

Highlights from the Phase 3 GEMINI 1 & GEMINI 2 Clinical Studies

• A total of 750 participants aged 40 to 55 years old with presbyopia were randomized in the two studies in a one-to-one ratio of placebo to Vuity.
• Participants were instructed to administer one drop of Vuity or placebo once daily in each eye.
• Both studies met their primary endpoints with a statistically significant proportion of participants treated with Vuity gaining three lines (the ability to read three additional lines on a reading chart) or more in mesopic (in low light), high contrast, binocular Distance Corrected Near Visual Acuity (DCNVA), without losing more than 1 line (5 letters) of Corrected Distance Visual Acuity (CDVA) at day 30, hour 3, versus placebo.
• There were no serious adverse events observed in any participants treated with Vuity in either clinical study. The most common treatment emergent non-serious adverse events occurring at a frequency of >5% in participants treated with Vuity were headache and eye redness.

FDA Approves Seglentis (celecoxib and tramadol hydrochloride) for the Management of Acute Pain

In continuation of my update on celecoxib and tramadol

The U.S. Food and Drug Administration (FDA) has approved Seglentis (celecoxib and tramadol hydrochloride), a proprietary product developed by Esteve Pharmaceuticals' R&D team. It is an innovative first-in-class product comprised of a co-crystal form of celecoxib (an anti-inflammatory) and tramadol (an analgesic) for the treatment of acute pain in adults. This is Esteve's first proprietary research product to enter the United States market.

In words of Dr. Carlos Plata-Salamán, Chief Scientific Officer and Chief Medical Officer of Esteve "This innovation is the result of applying a crystallization technology to improve the physicochemical properties and pharmacokinetic characteristics of its active pharmaceutical ingredients.1,2,4,7,9 The FDA approval means that clinicians and adult patients in the U.S. now have a new treatment option for acute pain management."

Seglentis is the trade name for tablets that contain a co-crystal7 composed of celecoxib and tramadol hydrochloride. It is a new analgesic designed for acute pain management in a multimodal treatment approach3,5,6 targeting four complementary pain relief mechanisms.5,6 It offers a new treatment option for acute pain management aligned with the multimodal analgesia now considered standard of care. 

The novel co-crystal structure produces a unique pharmacokinetic profile of its active pharmaceutical ingredients compared to their individual or combined administration.1,2,4,9 The New Drug Application (NDA) was approved by the U.S. FDA on October 15, 2021.

Staffan Schüberg, Chief Executive Officer of Esteve, said: "We are proud of this milestone as we understand it as a recognition of our daily efforts to meet patient’s needs and to address the challenges the pain community is facing nowadays".

FDA Approves Zimhi (naloxone hydrochloride) Injection for the Treatment of Opioid Overdose

In continuation of my update on naloxone hydrochloride, Adamis Pharmaceuticals Corporation (Nasdaq: ADMP) announced   the U.S. Food and Drug Administration (FDA)   approval of  Adamis’ Zimhi™ (naloxone HCL Injection, USP) 5 mg/0.5 mL product. Zimhi is a high-dose naloxone injection product FDA-approved for use in the treatment of opioid overdose.

Naloxone is an opioid antagonist and is generally considered the drug of choice for immediate administration for opioid overdose. It works by blocking or reversing the effects of the opioid, including extreme drowsiness, slowed breathing, or loss of consciousness. Common opioids include morphine, heroin, tramadol, oxycodone, hydrocodone and fentanyl.

According to statistics published by the Centers for Disease Control and Prevention (CDC), drug overdoses resulted in approximately 96,779 deaths in the United States during the 12-month period ending March 2021, which was a 29% increase over the prior 12-month period. Drug overdoses are now the leading cause of death for Americans under age 50, with more powerful synthetic opioids, like fentanyl and its analogues, responsible for the largest number of those deaths.

Dr. Jeffrey Galinkin, an anesthesiologist, and former member of the FDA Advisory Committee for Anesthetics, Analgesics and Addiction Products, commented, “I am pleased to see this much needed high dose naloxone product will become part of the treatment tool kit as a countermeasure to the continued surge in fentanyl related deaths. The higher intramuscular doses of naloxone in Zimhi should result in more rapid and higher levels of naloxone in the systemic circulation, which in turn, should result in more successful resuscitations.”

Dr. Dennis J. Carlo, President and CEO of Adamis, stated, “We are very excited by this approval and are working with our commercial partner, US WorldMeds, to make this much-needed, lifesaving product readily available to the market. Zimhi provides the highest systemic levels of naloxone compared to any of the nasal or intramuscular products currently available.”

P. Breckinridge Jones, Sr., CEO of US WorldMeds, added, “We are pleased with the approval and now look forward to commercially marketing Zimhi in the United States. US WorldMeds has a proven track-record of successfully commercializing pharmaceutical products and have a First-in-Class and only FDA-approved product, LUCEMYRA® (lofexidine), for the treatment of withdrawal symptoms associated with abrupt opioid discontinuation. We are confident we can leverage our existing commercial infrastructure and presence in the opioid dependence market to speed the uptake of Zimhi and combat the growing opioid crisis. We are preparing for the full commercial launch of ZIMHI which is planned for the first quarter of 2022.”\

Progress towards new treatments for tuberculosis

Boosting the body's own disease-fighting immune pathway could provide answers in the desperate search for new treatments for tuberculosis.

Tuberculosis still represents an enormous global disease burden and is one of the top 10 causes of death worldwide.

Led by WEHI's Dr. Michael Stutz and Professor Marc Pellegrini and published in Immunity, the study uncovered how cells infected with tuberculosis bacteria can die, and that using new medicines to enhance particular forms of cell death decreased the severity of the disease in a preclinical model.

Fighting antibiotic resistance

Tuberculosis is caused by bacteria that infect the lungs, spreading from person to person through the air. A challenge in the fight against tuberculosis is that the bacteria that cause the disease have developed resistance to most antibiotic treatments, leading to a need for new treatment approaches.

Tuberculosis bacteria grow within immune cells in the lungs. One of the ways that cells protect against these 'intracellular' pathogens is to undergo a form of cell death called apoptosis—destroying the cell as well as the microbes within it.

Using preclinical models, researchers sequentially deleted key apoptosis effectors, to demonstrate their roles in controlling tuberculosis infections. This demonstrated that a proportion of tuberculosis-infected cells could die by apoptosis—opening up new opportunities for controlling the disease.

Using host-directed therapies to reduce disease burden

Dr. Stutz said researchers then tested new drugs that force cells to die. This revealed that a drug-like compound that inhibits cell death-regulatory proteins called IAPs could promote death of the infected cells.

"When we treated our infection models with this compound, we were able to significantly reduce the amount of tuberculosis disease," he said.

"The longer the treatment was used, the greater the reduction of disease."

The research team was able to replicate these results using various different IAP inhibitors.

"Excitingly, many of these compounds are already in clinical trials for other types of diseases and have proven to be safe and well-tolerated by patients," Dr. Stutz said.

"We predict that if these compounds were progressed for treating tuberculosis, they would be most effective if used alongside existing antibiotic treatments."

Opening the door to new treatment methods

Professor Marc Pellegrini said until now, antibiotics were the only treatment for tuberculosis, which were limited in their application due to increasing antibiotic resistance.

"Unlike antibiotics, which directly kill bacteria, IAP inhibitors kill the cells that the tuberculosis bacteria need to survive," he said.

"The beauty of using a host-directed therapy is that it doesn't directly target the microbe, it targets a host process. By targeting the host rather than the microbe, the chances of resistance developing are incredibly low."

The team hope the research will lead to better treatments for tuberculosis.

"This research increases our understanding of the types of immune responses that are beneficial to us, and this is an important step towards new treatments for tuberculosis, very few of which have been developed in the last 40 years," Dr. Stutz said.

"We have demonstrated that host-directed therapies are viable for infections such as tuberculosis, which is particularly important in the era of extensive antibiotic resistance."

Oral Transglutaminase 2 Inhibitor Beneficial in Celiac Disease

For patients with celiac disease, treatment with a selective oral transglutaminase 2 inhibitor (ZED1227) attenuates gluten-induced duodenal mucosal damage, according to a study published in the July 1 issue of the New England Journal of Medicine.

Detlef Schuppan, M.D., Ph.D., from the Johannes Gutenberg University in Mainz, Germany, and colleagues conducted a proof-of-concept trial of a six-week treatment with ZED1227 at three dose levels versus placebo among adults with well-controlled celiac disease who underwent a daily gluten challenge. The primary end point of attenuation of gluten-induced mucosal damage was assessed among 35, 39, 38, and 30 patients assigned to 10-mg, 50-mg, and 100-mg ZED1227 and placebo, respectively.

The researchers found that at all three dose levels, ZED1227 treatment attenuated gluten-induced duodenal mucosal injury. From baseline to week six, the mean ratio of villus height to crypt depth estimated difference from placebo was 0.44, 0.49, and 0.48 in the 10-, 50-, and 100-mg groups, respectively. For the change in intraepithelial lymphocyte density, the estimated differences from placebo were −2.7, −4.2, and −9.6 cells per 100 epithelial cells, respectively, for 10-, 50-, and 100-mg ZED1227. Symptom and quality-of-life scores may have been improved with use of the 100-mg dose.

"Although this trial is very encouraging, whether treatment with ZED1227, and more generally transglutaminase 2 inhibition, in patients with celiac disease will be efficient in real life and during long-term gluten exposure remains to be determined," writes the author of an accompanying editorial.

Bayer Wins Approval for CKD Drug ......

The U.S. Food and Drug Administration (FDA) greenlit Bayer’s Kerendia (finerenone) to reduce the progression of chronic kidney disease associated with type 2 diabetes. The first nonsteroidal mineralocorticoid receptor antagonist (MRA) is approved for adults with chronic kidney disease associated with type 2 diabetes. 

Kerendia was explicitly approved to reduce the risk of kidney failure, heart attack, heart failure hospitalization, and cardiovascular death in adult patients with chronic kidney disease associated with type 2 diabetes. Although there are guideline directed therapies for CKD, many patients with chronic kidney disease associated with type 2 diabetes are at risk for disease progression and cardiovascular events. 

Amit Sharma, Vice President of Cardiovascular and Renal at Bayer, expressed excitement at bringing this new treatment for patients with CKD associated with type 2 diabetes. 

Kerendia acts by blocking the overactivation of the mineralocorticoid receptor, which contributes to fibrosis and inflammation. Those can then contribute to permanent structural kidney damage. 

“Chronic kidney disease associated with type 2 diabetes can have such a debilitating impact on patients’ lives. Unfortunately, this disease is far reaching, as up to 40 percent of all patients with type 2 diabetes develop chronic kidney disease,” Kevin Longino, chief executive officer of the National Kidney Foundation and a kidney transplant patient, said in a statement. “It is important for physicians and patients to have new treatment options that can slow chronic kidney disease progression.”

The FDA approved Kerendia based on data from the Phase III FIDELIO-DKD study. The trial demonstrated positive kidney and cardiovascular outcomes in patients with CKD associated with type 2 diabetes. 

Trial findings were published in the New England Journal of Medicine in 2020. Type 2 diabetes is the leading cause of end-stage kidney disease, when patients may need dialysis or a kidney transplant to stay alive. It is estimated that about 40% of all type 2 diabetes patients will develop chronic kidney disease. 

George Bakris, the lead study investigator for the FIDELIO-DKD study, said the patient populations included in the Phase IIII study were at risk of disease progression despite being on the current standard of care treatment to control blood pressure and blood glucose. The approval of Kerendia provides physicians with a treatment option that can give kidney protection, he said. 

Bayer expects Kerendia to be available for patients by the end of the month. The company is seeking approval in Europe. Kerendia was approved under both Fast Track and Priority Review designations.

Drug could be promising new option against eczema

In continuation of my update on Upadacitinib

 

 

A pill called upadacitinib, already approved for treating rheumatoid arthritis, might also ease another common immunological condition—eczema.

In two phase 3 clinical trials, patients with moderate to severe eczema showed rapid and significant improvements after taking the drug, said researchers at Mount Sinai in New York City.

The clinical trials were funded by the dug's maker, AbbVie Inc., and included nearly 1,700 patients with the inflammatory skin condition.

"The results of these trials ... were so incredible that by week 16, most patients with moderate to severe atopic dermatitis [eczema] either had a 90% disease clearance, or even 100% disease clearance," study first author Dr. Emma Guttman-Yassky said in a Mount Sinai news release. She's professor and chair of the department of dermatology at Mount Sinai's Icahn School of Medicine, in New York City.

"We achieved extremely high clearance rates that are bringing us closer to the amazing clearance rates that we see in psoriasis," Guttman-Yassky noted.

According to the National Eczema Association, "people with eczema tend to have an over-reactive immune system that when triggered by a substance outside or inside the body, responds by producing inflammation. It is this inflammation that causes the red, itchy and painful skin symptoms common to most types of eczema."

Eczema affects more that 31 million American adults and between 10 to 20% of children, the study authors noted.

The two new clinical trials involved a total of almost 1,700 patients and took place between 2018 and 2020.

Besides the rapid disease clearance noted in patients, "the itch improvements already started to be significant within days from the beginning of the trials, and the maximum clinical efficacy was obtained early, at week 4, and maintained to week 16," Guttman-Yassky said.

The drug was well tolerated by patients who received the two highest doses of the drug—15 milligrams and 30 milligrams—and no significant safety risks were seen, she added.

Upadacitinib is already approved and marketed for use against rheumatoid arthritis under the brand name Rinvoq. It works by blocking what are known as multiple cytokine-signaling pathways—parts of the immune system that can malfunction and cause eczema.

According to Guttman-Yassky, other eczema therapies exist, but most come with certain drawbacks.

While injectable biologic drugs are highly successful in treating eczema patients who don't respond to or can't use topical creams, their use cannot be stopped and restarted at will, because the potential creation of anti-drug antibodies will shorten the half-life of the drugs, she explained.

However, "patients were able to start and restart [upadacitinib] at any time, allowing for flexibility, which cannot be achieved with biologics," Guttman-Yassky, said. "And, biologics, which are injectable agents that target specific lymphocytes that are 'misbehaving' or are up-regulated in atopic dermatitis, do not suppress the entire immune system as other immunosuppressants tend to do."

Dr. Michele Green is a dermatologist at Lenox Hill Hospital in New York City who wasn't involved in the new study.

She called the findings "important."

Upadacitinib is the first drug in its class "to be effectively used for patients with significant improvement of pruritus [itch] within several days of treatment and clearance of their disease within several weeks," Green noted.

"It is also significant since adolescents were included in this study and I believe an oral treatment is much more appealing to treating adolescents than current injectable biologics," she added.
