FDA Approves Zulresso (brexanolone) for the Treatment of Postpartum Depression

U.S. Food and Drug Administration   approved Zulresso (brexanolone) injection for intravenous (IV) use for the treatment of postpartum depression (PPD) in adult women. This is the first drug approved by the FDA specifically for PPD.

"Postpartum depression is a serious condition that, when severe, can be life-threatening. Women may experience thoughts about harming themselves or harming their child. Postpartum depression can also interfere with the maternal-infant bond. This approval marks the first time a drug has been specifically approved to treat postpartum depression, providing an important new treatment option," said Tiffany Farchione, M.D., acting director of the Division of Psychiatry Products in the FDA’s Center for Drug Evaluation and Research. "Because of concerns about serious risks, including excessive sedation or sudden loss of consciousness during administration, Zulresso has been approved with a Risk Evaluation and Mitigation Strategy (REMS) and is only available to patients through a restricted distribution program at certified health care facilities where the health care provider can carefully monitor the patient."

PPD is a major depressive episode that occurs following childbirth, although symptoms can start during pregnancy. As with other forms of depression, it is characterized by sadness and/or loss of interest in activities that one used to enjoy and a decreased ability to feel pleasure (anhedonia) and may present with symptoms such as cognitive impairment, feelings of worthlessness or guilt, or suicidal ideation.

Zulresso will be available only through a restricted program called the Zulresso REMS Program that requires the drug be administered by a health care provider in a certified health care facility. The REMS requires that patients be enrolled in the program prior to administration of the drug. Zulresso is administered as a continuous IV infusion over a total of 60 hours (2.5 days). Because of the risk of serious harm due to the sudden loss of consciousness, patients must be monitored for excessive sedation and sudden loss of consciousness and have continuous pulse oximetry monitoring (monitors oxygen levels in the blood). While receiving the infusion, patients must be accompanied during interactions with their child(ren). The need for these steps is addressed in a Boxed Warning in the drug’s prescribing information. Patients will be counseled on the risks of Zulresso treatment and instructed that they must be monitored for these effects at a health care facility for the entire 60 hours of infusion. Patients should not drive, operate machinery, or do other dangerous activities until feelings of sleepiness from the treatment have completely gone away.

The efficacy of Zulresso was shown in two clinical studies in participants who received a 60-hour continuous intravenous infusion of Zulresso or placebo and were then followed for four weeks. One study included patients with severe PPD and the other included patients with moderate PPD. The primary measure in the study was the mean change from baseline in depressive symptoms as measured by a depression rating scale. In both placebo controlled studies, Zulresso demonstrated superiority to placebo in improvement of depressive symptoms at the end of the first infusion. The improvement in depression was also observed at the end of the 30-day follow-up period.

The most common adverse reactions reported by patients treated with Zulresso in clinical trials include sleepiness, dry mouth, loss of consciousness and flushing. Health care providers should consider changing the therapeutic regimen, including discontinuing Zulresso in patients whose PPD becomes worse or who experience emergent suicidal thoughts and behaviors.

Dual-Drug Therapy May Boost Odds Against a Tough Breast Cancer

In continuation of my updates on  fulvestrant (Faslodex) and anastrozole (Arimidex)

           

 There's good news for women battling a particularly difficult form of advanced breast cancer.

In a new study of patients with so-called "hormone receptor-positive" breast cancer that's spread beyond the breast, women who received a combo of two anti-estrogen drugs right away lived many months more than those who got just one drug, the researchers found.

The drugs -- fulvestrant (Faslodex) and anastrozole (Arimidex) -- appear to work better when given together rather than using fulvestrant as a follow-up drug given after anastrozole, according to the team led by Dr. Rita Mehta. She's a clinical professor at the University of California, Irvine.

"These results are very exciting," said Mehta, who is also a member of the Southwest Oncology Group breast cancer research committee.

"Women who are treated with fulvestrant up front live about eight months longer. That's a lot of extra time to do the things you love with the people you love," she said in an Oregon Health & Science University news release.

"Women who received fulvestrant, right up front, lived longer based on this new long-term analysis. This is credible evidence that combination endocrine therapy should be considered an option for first-line treatment of advanced hormone receptor-positive breast cancer," Mehta said.

One breast cancer specialist who wasn't involved in the research agreed.

"Although metastatic breast cancer is not thought to be curable, it can be controlled for years and converted to a chronic disease that allows patients to carry on with their lives," explained Dr. Alice Police. She directs breast surgery at Northwell Health Cancer Institute in Sleepy Hollow, N.Y.

That's true for all advanced breast cancers, including the hormone receptor-positive tumors covered by this study. About two-thirds of all breast cancers are of this type, according to the American Cancer Society.

These hormone-sensitive tumors "love estrogen," Police noted, and so oncologists typically prescribe anti-estrogen drugs to help slow the disease.

"Typically, a patient is treated sequentially with different medications [such as fulvestrant and anastrozole], and switched to a different medication if their cancer spreads or grows," she explained.

But what if women got the two drugs in combination, right away?

To answer that question, Mehta's group tracked outcomes for over 700 postmenopausal women with breast cancer treated at 73 hospitals, clinics and cancer centers across the United States and Canada.

The investigators found that women who received both medicines as their first line of treatment lived an average of eight months longer than those who took anastrozole alone -- 50 months versus 42 months.

The study findings also showed that 42 percent of women who got the combo treatment were alive five years after their treatment, compared with 33 percent of women who got anastrozole alone.

About 45 percent of women treated with anastrozole alone were later treated with fulvestrant, when their cancer got worse or spread. But those who initially received fulvestrant had the best overall survival and progression-free survival, the researchers reported March 27 in the New England Journal of Medicine.

The study also found that patients in the combo-treatment group received lower-than-normal doses of fulvestrant in the trial: 250 milligrams (mg) per month after the first loading dose, compared with the typical 500 mg per month.

The two drugs work in slightly different ways. Anastrozole reduces the body's production of estrogen, while fulvestrant disables the tumor's ability to "feed" on circulating estrogen.

Mavenclad Approved for Multiple Sclerosis

In continuation of my update on Mavenclad (cladribine)

  

Mavenclad (cladribine) tablets have been approved by the U.S. Food and Drug Administration to treat relapsing multiple sclerosis (MS) in adults.

An agency news release said the drug is recommended for people who have had an inadequate response to, or are unable to tolerate, another medication approved for MS. Mavenclad is not sanctioned for a form of MS called clinically isolated syndrome.

MS is a chronic autoimmune disease of the central nervous system that disrupts communication between the brain and other parts of the body. Most people have initial symptoms between ages 20 and 40, more often in women than men. The disease progresses over time and typically leads to lifelong disability.

Mavenclad's effectiveness was shown in clinical studies involving 1,326 people with relapsing forms of MS who had least one relapse in the prior 12 months. The drug significantly decreased the number of relapses compared to a placebo, the FDA said.

Mavenclad must be dispensed with a patient medication guide that describes the drug's uses and risks. The medication's label includes a boxed warning of increased risk of cancer, worsening existing cancer, and fetal harm. The drug should not be used in pregnant women and among people of reproductive age who do not use contraception during treatment and for six months afterward, the FDA said. Mavenclad should be stopped if the user becomes pregnant.

Other significant warnings include a risk of a drop in white blood cells called lymphocytes, infections, bone marrow suppression and liver injury. The most common adverse reactions include upper respiratory tract infection and headache.

Celgene Corporation (NASDAQ:CELG)  announced that the Company has submitted a New Drug Application to the U.S. Food and Drug Administration (FDA) for ozanimod for the treatment of adults with relapsing forms of multiple sclerosis (RMS). Ozanimod is an oral, sphingosine 1-phosphate (S1P) receptor modulator, which binds with high affinity selectively to S1P subtypes 1 (S1P1) and 5 (S1P5).

The pivotal efficacy and safety data provided in the application result from the SUNBEAM™ and RADIANCE™ Part B phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled trials.

“New oral treatment options with differentiated profiles like ozanimod are needed to help address an unmet need for people with relapsing forms of MS,” said Jay Backstrom, M.D., Chief Medical Officer for Celgene. “With concurrent applications in the U.S. and EU, we look forward to advancing this promising medicine through the regulatory review process to provide a new option for the treatment of RMS in 2020.”

Earlier this month, the Company also submitted a Marketing Authorization Application to the European Medicines Agency for adults with relapsing-remitting multiple sclerosis.

Ozanimod is an investigational compound that is not approved for any use in any country.

About SUNBEAM™

SUNBEAM is a pivotal, phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled trial evaluating the efficacy, safety and tolerability of two doses of oral ozanimod (0.92 mg and 0.46 mg, equivalent to 1 mg and 0.5 mg ozanimod HCI respectively) against weekly intramuscular interferon beta-1a (Avonex®) for at least a 12-month treatment period. The study included 1,346 people living with RMS across 152 sites in 20 countries.

The primary endpoint of the trial was annualized relapse rates (ARR) during the treatment period. The secondary MRI endpoints included the number of new or enlarging hyperintense T2-weighted brain MRI lesions over 12 months, number of gadolinium-enhanced brain MRI lesions at month 12 and percent change from baseline in whole brain volume at month 12. Cortical grey and thalamic volume changes were also prospectively assessed versus active comparator.

An analysis of the time to onset of 3-month confirmed disability progression was pre-specified using pooled data from both the SUNBEAM and RADIANCE Part B phase 3 trials.

About RADIANCE™

RADIANCE Part B is a pivotal, phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled trial evaluating the efficacy, safety and tolerability of two doses of oral ozanimod (0.92 mg and 0.46 mg, equivalent to 1 mg and 0.5 mg ozanimod HCI respectively) against weekly intramuscular interferon beta-1a (Avonex®) over a 24-month treatment period. The study included 1,320 people living with RMS across 150 sites in 21 countries.

The primary endpoint of the trial was ARR over 24 months.

Eisai and Imbrium Therapeutics Announce U.S. FDA Filing Acceptance of New Drug Application for Lemborexant for the Treatment of Insomnia

In continuation of my update on lemborexant

Eisai Co., Ltd. (CEO: Haruo Naito, “Eisai”) and Imbrium Therapeutics L.P. (Imbrium Therapeutics), a clinical-stage biopharmaceutical company and operating subsidiary of Purdue Pharma, L.P. (President and CEO: Craig Landau, MD),  announced that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for lemborexant, an investigational agent being studied for the treatment of insomnia, a sleep-wake disorder. A Prescription Drug User Fee Act (PDUFA) date is set for December 27, 2019.

The NDA submission was based on data from the clinical development program including two pivotal Phase 3 studies of lemborexant – SUNRISE 1 (Study 304) and SUNRISE 2 (Study 303).

• SUNRISE 1: a one-month Phase 3 clinical study to evaluate the efficacy and safety of lemborexant versus placebo and versus an active comparator (zolpidem tartrate extended release, “zolpidem ER”) in 1,006 patients 55 years and older (45 percent of all patients were aged 65 years and older) with insomnia disorder. This study assessed sleep latency (using latency to persistent sleep; primary objective); sleep efficiency and wake after sleep onset (effect on maintaining sleep; key secondary objectives) objectively using polysomnography, and achieved its primary and key secondary objectives. The most common adverse events (AEs) reported in the lemborexant arms were headache and somnolence.1
• SUNRISE 2: a 12-month placebo-controlled (first six months) Phase 3 clinical study to evaluate the long-term efficacy and safety of lemborexant in 949 adult patients (18 to 88 years of age) with insomnia disorder. This study evaluated subjective (patient-reported) sleep onset latency (primary objective), sleep efficiency, and wake after sleep onset (key secondary objectives) using sleep diaries, and achieved its pre-specified primary and key secondary efficacy objectives. The most common AEs reported in the lemborexant arms were somnolence, nasopharyngitis, headache, and influenza.2

“Our ultimate goal for the development of a sleep-wake treatment is to bring to patients living with insomnia a new option that has the potential to improve their ability to fall asleep, stay asleep and wake the next morning without impairment,” said Lynn Kramer, MD, Chief Clinical Officer and Chief Medical Officer, Neurology Business Group, Eisai. “This milestone for lemborexant brings us one step closer to addressing unmet needs for millions of patients who experience insomnia.”

“Insomnia, a disorder of sleep quality and quantity, causes significant impairment in daily functioning and has long-term consequences for health and well-being,”3 said John Renger, PhD, Vice President, Head of Research & Development and Regulatory Affairs, Imbrium Therapeutics. “We are committed to working with our partner Eisai to make this investigational treatment available to patients, pending regulatory approval.”

Lemborexant is being jointly developed by Eisai and Imbrium Therapeutics for the treatment of multiple sleep-wake disorders, including insomnia disorder. Information about ongoing clinical studies is available at clinicaltrials.gov.

Eisai and Imbrium Therapeutics are striving to address new unmet medical needs and to improve the lives of patients and their families.

This release discusses investigational uses of an agent in development and is not intended to convey conclusions about efficacy or safety. There is no guarantee that such an investigational agent will successfully complete clinical development or gain health authority approval.

About Lemborexant

Lemborexant is a novel investigational small molecule compound, discovered and developed by Eisai in-house scientists, that inhibits orexin signaling by binding competitively to both orexin receptor subtypes (orexin receptor 1 and 2). In individuals with normal daily sleep-wake rhythms, orexin signaling is believed to promote periods of wakefulness. In individuals with sleep-wake disorders, it is possible that orexin signaling that regulates wakefulness is not functioning normally, suggesting that inhibiting inappropriate orexin signaling may enable initiation and maintenance of sleep. Eisai and Imbrium Therapeutics are investigating lemborexant as a potential treatment option for multiple sleep-wake disorders, such as insomnia. Additionally, a Phase 2 clinical study of lemborexant in patients with irregular sleep-wake rhythm disorder (ISWRD) and mild to moderate Alzheimer's dementia is underway.

About SUNRISE 1 (Study 304)

SUNRISE 1 was a multicenter, randomized, double-blind, placebo-controlled, active comparator, parallel-group study evaluating the efficacy and safety of lemborexant in 1,006 male or female adult patients 55 years and older (45 percent of patients were 65 years and older) with insomnia disorder conducted in North America and Europe. SUNRISE 1 included a pre-randomization phase of up to 35 days (including a two-week placebo run-in period) and a randomization phase comprised of a 30-day treatment period and a minimum two-week period without treatment prior to the end-of-study visit. In this study, patients were randomized to receive placebo or one of three treatment regimens (lemborexant 5 mg, lemborexant 10 mg, zolpidem ER 6.25 mg).

The primary objective for SUNRISE 1 was to demonstrate using polysomnography that lemborexant at either the 5 mg or 10 mg dose is superior to placebo on objective sleep onset, as measured by latency to persistent sleep after the last two nights of one month of treatment. Key secondary objectives included change from baseline in sleep efficiency and wake after sleep onset (WASO) for both lemborexant doses compared to placebo, and WASO in the second half of the night (WASO2H) for both lemborexant doses compared to zolpidem ER, each after the last two nights of one month of treatment.

About SUNRISE 2 (Study 303)

SUNRISE 2 was a 12-month multicenter, global, randomized, controlled, double-blind, parallel-group study of the efficacy and safety of lemborexant in 949 male or female adult participants 18 to 88 years of age with insomnia disorder. SUNRISE 2 included a pre-randomization phase of up to 35 days (including a two-week placebo run-in period) and a randomization phase comprised of a six-month placebo-controlled treatment period, a six-month period of active-only treatment and a two-week period without treatment prior to the end-of-study visit. In this study, during the placebo-controlled treatment period, patients were randomized to receive placebo or one of two treatment regimens (lemborexant 5 mg or 10 mg). During the active-only treatment period, patients who received placebo during the first period were re-randomized to receive lemborexant 5 mg or 10 mg. Patients who received active treatment during the first period continued on the treatment to which they were originally randomized.

The primary objective was change from baseline in subjective sleep onset latency after six months of placebo-controlled treatment using patient reported (subjective) sleep diaries. Key secondary endpoints were change from baseline in subjective sleep efficiency and subjective wake after sleep onset (sWASO) by using patient reported (subjective) sleep diaries for both lemborexant doses after six months of placebo-controlled treatment.

FDA Approves Mayzent (siponimod) for Secondary Progressive Multiple Sclerosis

 Novartis  announced that the US Food and Drug Administration (FDA) has approved Mayzent (siponimod) for the treatment of adults with relapsing forms of multiple sclerosis, including secondary progressive multiple sclerosis (SPMS) with active disease, relapsing remitting multiple sclerosis (RRMS) and clinically isolated syndrome (CIS)*. SPMS is a debilitating form of multiple sclerosis (MS) characterized by progressive and irreversible neurological disability[4]. Mayzent is expected to be available in the US in approximately one week**. Patients will not require a first dose observation (FDO, cardiac monitoring upon initiation) unless they have certain pre-existing cardiac conditions.

"One of the most important aims of MS treatment is delaying disability progression and preserving cognition," said Paul Hudson, Chief Executive Officer, Novartis Pharmaceuticals. "With Mayzent, SPMS patients with active disease will have access to the first effective oral therapy directed towards disease progression, even when MS transitions to a stage where deterioration is less dependent on the usual relapse activity. Mayzent is a testament to the Novartis mission to reimagine medicine. We are delighted that our ongoing commitment to stop MS has led to a much awaited treatment for these patients in need."

Most patients transition from RRMS to SPMS over time[2]. Therefore, starting therapy early is critical for patients to help slow the rate of disability progression. Disability progression most frequently includes - but is not limited to - an impact on ambulation, which could lead to patients needing a walking aid or a wheelchair, bladder dysfunction and cognitive decline[5]. 

"We are grateful that there is a new treatment option for adults with active secondary progressive MS," said Bruce Bebo, PhD, Executive Vice President, Research, US National MS Society. "We are hopeful this approval will stimulate a conversation between patients and healthcare professionals about disability progression after relapsing remitting MS and its early management."

The approval of Mayzent is based on groundbreaking data from the Phase III EXPAND study, a randomized, double-blind, placebo-controlled study, comparing the efficacy and safety of Mayzent versus placebo in people living with SPMS. Patients enrolled in EXPAND were representative of a typical SPMS population: at study initiation, patients had a mean age of 48 years, had been living with MS for approximately 16 years and more than 50% had a median Expanded Disability Status Scale (EDSS) score of 6.0 and relied on a walking aid[3]. Mayzent significantly reduced the risk of three-month confirmed disability progression (CDP) (primary endpoint; 21% reduction versus placebo, p=0.013; 33% reduction versus placebo in patients with relapse activity in the two years prior to screening, p=0.0100)[3]. Additionally, Mayzent meaningfully delayed the risk of six-month CDP (26% versus placebo, p=0.0058) and reduced the annualized relapse rate (ARR) by 55%[3]. Furthermore, EXPAND showed significant favorable outcomes in other relevant measures of MS disease activity, including cognition, MRI disease activity and brain volume loss (brain shrinkage)[3].

Most common adverse reactions (incidence greater than 10%) were headache, hypertension, and transaminase increase.

"With the approval of Mayzent, we now have a much-needed therapeutic option to address SPMS with active disease," said EXPAND Steering Committee member Bruce Cree, MD, PhD, MAS, Clinical Research Director and George A. Zimmermann Endowed Professor in Multiple Sclerosis, University of California, San Francisco, School of Medicine. "Importantly, healthcare professionals now have even more reason to help patients identify changing symptoms and uncover early signs of progression."

Novartis is committed to bringing Mayzent to patients worldwide, and additional regulatory filings are currently underway with other health authorities outside the US. Regulatory action for Mayzent in the European Union is anticipated in late 2019, with additional regulatory action anticipated in Switzerland, Japan, Australia and Canada this year.

*Clinically isolated syndrome (CIS) is defined as a first episode of neurologic symptoms that lasts at least 24 hours and is caused by inflammation or demyelination in the central nervous system[6].

**Time of availability may vary as healthcare providers integrate Mayzent into their practices.

U.S. FDA Grants Priority Review for Fedratinib New Drug Application in Myelofibrosis

Celgene Corporation (NASDAQ:CELG)   announced the U.S. Food and Drug Administration (FDA) has accepted the company’s New Drug Application (NDA) for fedratinib and granted a Priority Review. Fedratinib is a highly selective JAK2 inhibitor intended for the treatment of patients with myelofibrosis, a serious bone marrow disorder that disrupts the body’s normal production of blood cells.1 Under the Prescription Drug User Fee Act, the FDA has set its action date as Sept. 3, 2019.

  

“The acceptance of the NDA and granting of Priority Review for fedratinib represent the first potential new treatment option after many years for patients affected by myelofibrosis.” said Jay Backstrom, M.D., Chief Medical Officer for Celgene. “Patients with myelofibrosis, including the number who are ineligible for or failed existing therapy continues to increase, representing a well-defined unmet medical need. We believe fedratinib can play an important role in the treatment of myelofibrosis and we look forward to working with the FDA as the review process advances.”

The NDA for fedratinib is based on results from a randomized, placebo-controlled, phase 3 trial (JAKARTA)in patients with primary or secondary myelofibrosis, as well as a single-arm, open-label phase 2 trial (JAKARTA2) in patients with primary or secondary myelofibrosis previously exposed to ruxolitinib, the only FDA-approved treatment for the disease. Results of these two trials have been previously published in peer-reviewed journals. The FDA has also provided fedratinib Orphan Drug designation for the treatment of secondary and primary myelofibrosis.

Celgene also plans to evaluate fedratinib in combination with luspatercept.

The NDA filing is based on the successful completion of four clinical trials – two pivotal studies, ACHIEVE I and ACHIEVE II, which demonstrated the efficacy, safety and tolerability of ubrogepant, as well as two additional safety studies. A 10-month review period has been assigned with the Prescription Drug User Fee Act (PDUFA) in the fourth quarter of 2019.

"Following the acceptance and expected review of this NDA, we anticipate ubrogepant to be the first approved oral CGRP receptor antagonist for the acute treatment of migraine, and may be used in conjunction with other available migraine treatments," said David Nicholson, Chief Research and Development Officer, Allergan. "As a leader in Chronic Migraine research for more than 20 years, Allergan looks to provide options for patients who need new acute and preventative treatments for migraine. In addition to ubrogepant, we are continuing to advance the Phase 3 clinical program for atogepant, the company's second orally-administered investigational CGRP receptor antagonist specifically for migraine prevention."

In the four clinical studies (ACHIEVE I, ACHIEVE II, UBR-MD-04 and 3110-105-002) supporting the NDA, ubrogepant demonstrated efficacy, safety and tolerability in the acute treatment of migraine among a broad patient population, including those who had an insufficient response to a triptan or those patients in whom triptans were contraindicated, as well as in patients who had moderate to severe CV risk profile. Following are topline results from the key clinical studies:

Phase 3 Clinical Trials (ACHIEVE I & ACHIEVE II)

The two pivotal Phase 3 clinical trials demonstrated the efficacy, safety and tolerability of orally administered ubrogepant (ACHIEVE I at 50 mg and 100 mg; and ACHIEVE II at 25 mg and 50 mg) compared to placebo to treat a single migraine attack in adults.

• The 50 mg and 100 mg doses met the studies' co-primary endpoints, demonstrating a statistically significant greater percentage of ubrogepant patients achieving pain freedom and absence of most bothersome symptom at two hours after the initial dose as compared to placebo patients; there was continued separation from placebo up to 48 hours.
• The 50 mg and 100 mg doses also met key secondary endpoints, demonstrating a statistically significant greater percentage of ubrogepant patients achieving pain relief at two hours after the initial dose compared to placebo patients.

Additional Safety Studies (UBR-MD-04 & 3110-105-002)

Study UBR-MD-04: Phase 3, multicenter, randomized, 52-week open-label extension trial in which adults with migraine were randomized 1:1:1 to usual care, ubrogepant 50 mg, or ubrogepant 100 mg to assess long-term safety and tolerability.

• Intermittent use of ubrogepant 50 mg or 100 mg for the acute treatment of migraine attacks over one year was well-tolerated. The three most frequently reported adverse events were nasopharyngitis, upper respiratory tract infection and sinusitis.

Study 3110-105-002: Phase 1, multicenter, double-blind, parallel-group trial evaluated the safety and tolerability of ubrogepant 100 mg, focusing on hepatic safety in healthy participants administered high frequency intermittent  dosing (2 days of ubrogepant 100 mg followed by 2 days of placebo for 8 consecutive weeks).

• Ubrogepant 100 mg was well-tolerated following frequent dosing and was not associated with persistent increases in ALT/AST compared to placebo, supporting liver safety.

"Despite its prevalence and burden, migraine remains an undertreated disease, with many patients continuing to seek additional treatment options from their physicians," said Dr. Jessica Ailani, a neurologist and Director of the Medstar Georgetown Headache Center. "If approved, ubrogepant, the first innovation in the acute treatment of migraine in over 25 years, will be used across the entire spectrum of the disease (from episodic to chronic) helping patients achieve relief in the moments when they most demand it."

About Ubrogepant

Ubrogepant is a novel, highly potent, orally-administered CGRP receptor antagonist in development for the acute treatment of migraine. CGRP and its receptors are expressed in regions of the nervous system associated with migraine pathophysiology. CGRP receptor antagonism is a novel mechanism of action for the acute treatment of migraine that clearly differs from the mechanisms of currently available triptans (serotonin 1B/1D agonists), opioids and ergots.
