FDA Approves Trikafta (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for Cystic Fibrosis Patients Ages 12 and Older Who Have at Least One F508del Mutation

In continuation of my update on  tezacaftor  and ivacaftor

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced the U.S. Food and Drug Administration (FDA) has approved Trikafta (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for the treatment of cystic fibrosis (CF) in people ages 12 years and older who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, the most common CF-causing mutation. With this approval, for the first time, approximately 6,000 people with CF ages 12 years and older who have one F508del mutation and one minimal function mutation (F/MF) have a medicine that targets the underlying cause of their CF. Additionally, approximately 12,000 people with one or two F508del mutations who are currently eligible for one of Vertex’s three other FDA-approved CF medicines are now also eligible for Trikafta.

“Today marks a milestone for CF patients, their families and Vertex. After a 20-year journey together, we have received FDA approval of Trikafta: a single breakthrough medicine with the potential to treat up to 90% of all people with CF in the future. For approximately 6,000 people with CF in the U.S., Trikafta is the first medicine that can treat the underlying cause of their disease,” said Jeffrey Leiden, M.D., Ph.D., Vertex's Chairman, President and Chief Executive Officer. “I want to personally thank the hundreds of Vertex scientists who have been working on this program for nearly 20 years – many of whom have dedicated their entire careers to changing the course of this disease; the CF Foundation which has provided support, encouragement and help throughout the journey; and most importantly the thousands of patients, caregivers, doctors and advocates who have courageously and persistently worked side-by-side with us to get to where we are today.”

“Today’s approval is a historic moment in cystic fibrosis care, with the potential for more people to benefit from CFTR modulator therapy to treat the basic defect of their disease,” said Steven Rowe, M.D., Director, Gregory Fleming James Cystic Fibrosis Research Center, University of Alabama at Birmingham. “In clinical trials, Trikafta was generally well tolerated and demonstrated improvements in multiple outcome measures in CF, including improvements in FEV1, improvements in respiratory symptoms and, in the 24-week F/MF study, a reduced rate of pulmonary exacerbations and improvements in BMI.”

“The incredible speed of this approval underscores our shared sense of urgency with the FDA and the CF community for bringing this medicine to eligible people with CF, particularly those without a medicine targeting the underlying cause of their disease,” said Reshma Kewalramani, M.D., Executive Vice President, Global Medicines Development and Medical Affairs and Chief Medical Officer at Vertex. “We remain committed to relentlessly pursuing the development of transformative therapies for all people living with this disease.”

Vertex has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for the elexacaftor/tezacaftor/ivacaftor combination regimen. Vertex is currently evaluating elexacaftor/tezacaftor/ivacaftor in people ages 6 through 11 with F/MF and F/F CF mutations in an ongoing Phase 3 study and is committed to evaluating elexacaftor/tezacaftor/ivacaftor in children <6 years of age as part of planned future studies.

FDA Approves Amzeeq (minocycline) Topical Foam for the Treatment of Moderate to Severe Acne

Foamix Pharmaceuticals Ltd. (Nasdaq: FOMX) (“Foamix” or the “Company”), a specialty pharmaceutical company, announced  the U.S. Food and Drug Administration (FDA)   approval of its novel Amzeeq (minocycline) topical foam, 4%. Amzeeq, formerly known as FMX101, is indicated for the treatment of inflammatory lesions of non-nodular moderate to severe acne vulgaris in adults and pediatric patients 9 years of age and older and is the first topical minocycline to be approved by the FDA for any condition.

“The FDA approval of Amzeeq is a milestone moment in dermatology and the most significant advancement with minocycline in almost 50 years,” said David Domzalski, Chief Executive Officer of Foamix. “We are proud that our proprietary technology platform has led to this new treatment option, which we believe can help address unmet treatment needs for moderate to severe acne patients. We are looking forward to bringing Amzeeq to market in January 2020, and to our Company’s first commercial launch.”

Minocycline is a broad-spectrum antibiotic known for its efficacy in treating moderate to severe acne, but its use is limited in some patients due to systemic side effects when taken orally. Until now, minocycline has not been available as a topical treatment due to its instability in traditional topical formulations. In Amzeeq, Foamix has leveraged its proprietary Molecule Stabilizing Technology (MST™) platform to effectively deliver minocycline in a foam-based vehicle.  

“Our innovative MST™ technology allowed us to develop a topical formulation of minocycline in a convenient, once-daily treatment regimen that maintains the stability of the active ingredient while delivering it into the skin,” said Iain Stuart, Ph.D, Chief Scientific Officer of Foamix. “The approval of Amzeeq represents a significant step toward our goal of enhancing the standard of care for the millions of acne sufferers in the U.S. who deserve alternatives in treatment.”

“The approval of Amzeeq is exciting news that provides a much-needed option in the treatment of moderate to severe acne,” said Linda Stein Gold, M.D., Director of Dermatology Clinical Research and Division Head of Dermatology at Henry Ford Health System in Detroit, Michigan. “Minocycline has been a trusted staple in acne treatment for decades, but has only been available in oral or systemic formulations. With the approval of Amzeeq, I can now offer my patients a new, effective topical treatment option with a favorable tolerability profile.”

The FDA approval of Amzeeq is supported by data from three Phase 3 clinical trials in 2,418 patients of 9 years of age or older, making it one of the largest clinical programs for acne to date. In each 12-week, multicenter, randomized, double-blind, vehicle-controlled study, subjects with moderate to severe acne vulgaris were treated once-daily with Amzeeq or vehicle. No other topical or systemic acne medication was permitted to be used by subjects during the study period. The studies each found statistically significant disease improvement with Amzeeq versus vehicle for the co-primary endpoint of absolute reduction of inflammatory lesions, while studies 2 and 3 demonstrated a statistically significant improvement in IGA treatment success. IGA treatment success was defined as a score of 0 (“clear”) or 1 (“almost clear”) and at least a two-point decrease from baseline. Amzeeq was well-tolerated and no treatment-related serious adverse events were reported. The most common adverse reaction was headache, which was reported in 3% of subjects treated with Amzeeq versus 2% of subjects treated with vehicle.

FDA Approves Secuado (asenapine) Transdermal System for the Treatment of Adults with Schizophrenia

In continuation of my update on Asenapine

Noven Pharmaceuticals, Inc., a wholly-owned subsidiary of Hisamitsu Pharmaceutical Co., Inc., has announced the U.S. Food and Drug Administration (FDA) has approval of  Secuado (asenapine) transdermal system, the first-and-only transdermal patch formulation for the treatment of adults with schizophrenia.As people living with schizophrenia cycle through treatments their therapeutic options narrow, leaving them and their caregivers looking for new treatment options,” said Leslie Citrome, M.D., M.P.H., Clinical Professor of Psychiatry and Behavioral Sciences, New York Medical College. “In addition to offering a new delivery option, transdermal patches can also provide caretakers and healthcare providers with a non-intrusive, visual confirmation that a treatment is being utilized.”

The once-daily transdermal drug delivery system (TDDS) provides sustained concentrations during wear time (24 hours)2 of the atypical antipsychotic drug asenapine, a well-established treatment for schizophrenia. A transdermal patch may help to mitigate some of the challenges patients face with the management of their schizophrenia.

“There is an enormous unmet need for new types of schizophrenia treatments, and Noven is committed to giving people living with this devastating disease and their family members new options that may help them effectively manage their symptoms,” said Dr. Naruhito Higo, Chairman and Chief Executive Officer, Noven Pharmaceuticals, Inc. “We commend the FDA on the approval of Secuado and look forward to bringing it to market in the U.S. as soon as possible so people living with schizophrenia have a transdermal delivery option for asenapine treatment.”

In the international, Phase 3, double-blind, placebo-controlled study, Secuado achieved the primary endpoint of statistically significant improvement from baseline in the change of the total Positive and Negative Syndrome Scale (PANSS) compared to placebo at week six. Efficacy and safety were assessed during the six-week treatment period in 616 adults living with schizophrenia. Additionally, Secuado demonstrated statistically significant improvement in Clinical Global Impression-Severity (CGI-S) scores, the key secondary endpoint of the Phase 3 study.

The systemic safety profile of Secuado was consistent with what is known for sublingual asenapine. The most commonly observed adverse reactions were extrapyramidal disorder, application site reaction, and weight gain.

FDA Approves Reyvow (lasmiditan), the First Serotonin (5-HT) 1F Receptor Agonist for the Acute Treatment for Migraine

Eli Lilly and Company (NYSE: LLY) announced today that the U.S. Food and Drug Administration (FDA) has approved Reyvow (lasmiditan) an oral medication for the acute treatment of migraine, with or without aura, in adults. Reyvow has a unique mechanism of action and is the first and only FDA-approved medicine in a new class of acute treatment for migraine (serotonin (5-HT)1F receptor agonists).

"Millions of people with migraine face an ongoing battle with the unresolved pain and symptoms of a migraine attack. There is a substantial unmet need for new acute treatments for migraine, like Reyvow, which is why we are proud of today's approval and Lilly's continuing contribution to the migraine community," said Gudarz Davar, M.D., vice president, neurology development, Lilly Bio-Medicines. "New expectations have been set in migraine care; pain freedom is now the treatment goal for people living with migraine and those who treat them. At Lilly, we are pioneering innovative medicines to provide new options for patients with migraine."

As with other medicines with central nervous system (CNS) activity, the FDA required abuse potential studies for Reyvow. Abuse potential refers to the likelihood that abuse will occur with a particular drug product or substance with CNS activity. Consistent with the FDA's guidance, Lilly conducted a human abuse potential assessment; as part of that assessment, therapeutic doses of Reyvow were associated with less drug liking when compared to alprazolam, but more than placebo. The recommended controlled substance classification for Reyvow is currently under review by the Drug Enforcement Administration (DEA) and is expected within 90 days of today's FDA approval, after which Reyvow will be available to patients in retail pharmacies.

"As a physician who specializes in the treatment of migraine and headache disorders, I commonly treat patients who are looking for acute treatment options that offer the chance for pain freedom during migraine attacks. This approval is especially significant because migraine pain is so often severe and incapacitating," said Jan Brandes, M.D., MS, FAAN, assistant clinical professor, Department of Neurology, Vanderbilt University. "With new science comes new hope. Considering up to 40% of people with migraine do not get adequate responses from their initial acute treatment prescription, having a new and novel option like Reyvow is an important development for physicians and the patients we treat.

The New Drug Application (NDA) for Reyvow included data from two Phase 3 single-attack studies (SAMURAI and SPARTAN), which evaluated the safety and efficacy of Reyvow for the acute treatment of migraine in adults. Both studies met the efficacy endpoints of pain freedom and freedom from most bothersome symptom (MBS; patient selected from nausea, sensitivity to light, or sensitivity to sound) at two hours following administration of Reyvow in comparison to placebo. Treatment emergent adverse events were generally mild to moderate and the most frequent included dizziness, fatigue, paresthesia (tingling or numbing sensation on the skin), sedation (sleepiness or drowsiness), nausea and/or vomiting and muscle weakness. See additional Important Safety Information below.

The Reyvow Phase 3 development program, including the open-label GLADIATOR study, involved more than 4,000 patients and the treatment of more than 20,000 migraine attacks.

"For over 25 years, Lilly has been committed to helping people affected by disabling headache disorders, investigating more than a dozen different compounds," said Patrik Jonsson, senior vice president and president, Lilly Bio-Medicines. "The approval of Reyvow is an exciting development for patients and physicians seeking the potential for pain freedom when a migraine attack happens."

FDA Approves Quzyttir (cetirizine) Injection for the Treatment of Acute Urticaria

The U.S. Food and Drug Administration (FDA) has approved Quzyttir (cetirizine hydrochloride) injection for the treatment of acute urticaria in adults and children 6 months of age and older. Quzyttir will be available as 10-mg/mL single-use vials for intravenous use.

The safety and efficacy of Quzyttir was demonstrated in a randomized, active-controlled, double-blind, single dose, multicenter, parallel group trial of 262 patients aged 18 years of age and older who presented to an emergency department or urgent care center with acute urticaria. Patients were treated with either 10 mg of Quzyttir, or 50 mg diphenhydramine injection. The primary efficacy endpoint was the change from baseline in patient-rated pruritus score assessed 2 hrs post treatment. 

Quzyttir injection was demonstrated to be non-inferior to the effectiveness of diphenhydramine injection. Additionally, the proportion of patients returning to any emergency department or clinic was lower in the Quzyttir treatment group (6%) compared to the diphenhydramine treatment group (14%), and the time spent in the treatment center was shorter.

The adverse reactions with Quzyttir occurred at an incidence of less than 1% and include: dyspepsia, feeling hot, dysgeusia, headache, paresthesia, presyncope, and hyperhidrosis.

Quzyttir is the first intravenous (IV) formulation of the histamine-1 (H1) receptor antagonist cetirizine. The first oral formulation of cetirizine was approved under the brand name Zyrtec in 1995

FDA Approves Scenesse (afamelanotide) for Prevention of Phototoxicity in Erythropoietic Protoporphyria

The U.S. Food and Drug Administration  has  granted approval to Scenesse (afamelanotide) to increase pain-free light exposure in adult patients with a history of phototoxic reactions (damage to skin) from erythropoietic protoporphyria.

For patients who are suffering from erythropoietic protoporphyria, a rare disorder, exposure to light may be extremely painful. Prior to today’s approval, there were no FDA-approved treatments to help erythropoietic protoporphyria patients increase their light exposure,” said Julie Beitz, M.D., director of FDA’s Center for Drug Evaluation and Research Office of Drug Evaluation III. “Today’s approval is one example of the FDA’s ongoing commitment to encourage industry innovation of therapies to treat rare diseases, and work with drug developers to make promising new therapies available to patients as safely and efficiently as possible.”

Erythropoietic protoporphyria is a rare disorder caused by mutations leading to impaired activity of ferrochelatase, an enzyme involved in heme production. Heme is an important component in hemoglobin, the oxygen carrying molecule in red blood cells. The decrease in ferrochelatase activity leads to an accumulation of protoporphyrin IX (PPIX) in the body. Light reaching the skin can react with PPIX causing intense skin pain and skin changes, such as redness and thickening. Scenesse (afamelanotide), a melanocortin-1 receptor (MC1-R) agonist, increases the production of eumelanin in the skin independent of exposure to sunlight or artificial light sources.  It is an implant that is administered subcutaneously (inserted under the skin). 

The efficacy of Scenesse was established in two parallel group clinical trials with patients with erythropoietic protoporphyria who received Scenesse or placebo form of the implant subcutaneously every two months. The first clinical trial enrolled 93 subjects, of whom 48 received Scenesse, and were followed for 180 days. The primary endpoint was the total number of hours over 180 days spent in direct sunlight between 10 a.m. and 6 p.m. on days with no pain. The median total number of hours over 180 days spent in direct sunlight between 10 a.m. and 6 p.m. on days with no pain was 64 hours for patients receiving Scenesse and 41 hours for patients taking placebo.

The second clinical trial enrolled 74 patients, of whom 38 received Scenesse, and were followed for 270 days. The primary endpoint was the total number of hours over 270 days spent outdoors between 10 am and 3 pm on days with no pain for which “most of the day” was spent in direct sunlight. The analysis did not include sun exposure on days patients reported spending time in a combination of both direct sunlight and shade. The median total number of hours over 270 days spent outdoors between 10 am and 3 pm on days with no pain for which “most of the day” was spent in direct sunlight was six hours for patients receiving Scenesse and 0.75 hours for patients receiving placebo. 

Scenesse’s most common side effects are implant site reaction, nausea, oropharyngeal (part of the throat just behind the mouth, where the oral cavity starts) pain, cough, fatigue, skin hyperpigmentation, dizziness, melanocytic nevus (moles), respiratory tract infection, somnolence (feeling drowsy), non-acute porphyria (build-up of normally occurring molecules created during heme production) and skin irritation. Scenesse should be administered by a health care professional who is proficient in the subcutaneous implantation procedure and has completed the applicant-provided training. Scenesse may induce skin darkening, and a full body skin examination is recommended for patients twice a year. In addition, patients are encouraged to maintain sun protection measures during treatment with Scenesse to prevent phototoxic reactions related to erythropoietic protoporphyria.

The FDA granted this application Priority Review designation. Scenesse also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.The approval of Scenesse was granted to Clinuvel.

FDA Approves Bonsity (teriparatide injection) to Treat Osteoporosis

In continuation of my update on teriparatide

Pfenex Inc. (NYSE American: PFNX) announced today that the U.S. Food and Drug Administration (FDA) has approved the new drug application (“NDA”) for Bonsity (PF708) submitted under the 505(b)(2) regulatory pathway, with Forteo® (teriparatide injection) as the reference drug. Like Forteo, the FDA-approved PF708 product is indicated for the treatment of osteoporosis in certain patients at high risk for fracture. 

“The FDA’s approval of Bonsity marks a major milestone in Pfenex’s history as our first approved commercial product and further validates our Pfēnex Expression Technology platform. We look forward to continuing to work with our commercialization partner Alvogen to launch PF708 in the U.S. We believe PF708 has the potential to significantly enhance patient access to an important therapy as a cost-effective alternative to Forteo, which had $1.6 billion in global sales in 2018,” said Eef Schimmelpennink, Chief Executive Officer of Pfenex.

Pfenex is also asking the FDA to designate PF708 as therapeutically equivalent (“A” rated) to Forteo, which would permit PF708 to be automatically substituted for Forteo in many states. To further support an “A” rating, Pfenex is conducting a comparative human factors study between PF708 and Forteo as requested by FDA. Pfenex anticipates submitting the final study report to the FDA as early as the second half of October 2019 and believes that this completes the information package required by the FDA to evaluate the therapeutic equivalence of PF708.

“Looking ahead, we are confident in the planning that Alvogen has done thus far in preparation for the commercial launch of PF708 and their established sales and marketing teams are excited to bring PF708 to market. To optimize patient and payer impact, we currently expect our commercial partner Alvogen to launch PF708 upon an FDA decision on the therapeutic equivalence rating,” concluded Mr. Schimmelpennink.

FDA Approves Aklief (trifarotene) Cream, a New Topical Retinoid for the Treatment of Acne

Galderma, a global leader focused on meeting the world's increasing skin health needs, announced today that the U.S. Food and Drug Administration (FDA) approved Aklief (trifarotene) Cream, 0.005% for the topical treatment of acne. Aklief Cream is the only topical retinoid that selectively targets retinoic acid receptor (RAR) gamma, the most common RAR found in the skin.1,2,3 Trifarotene is the first new retinoid molecule to receive U.S. FDA approval for the treatment of acne in more than 20 years.4,5,6 Aklief Cream is the first topical treatment specifically studied and proven to treat both facial (forehead, cheeks, nose and chin) and truncal (chest, shoulders and back) acne, offering healthcare professionals and acne patients another treatment option.

"While retinoids are foundational therapies to treat acne, there has been little innovation in decades.” said Sandra Johnson, M.D., FAAD, an investigator in the clinical trials of Aklief Cream and a dermatologist at Johnson Dermatology in Fort Smith, Arkansas. “With the approval of Aklief Cream, I am excited to offer my patients a unique, highly targeted retinoid that reduces inflammatory lesions on the face, back, chest and shoulders, that has also been shown to be safe and well-tolerated."

The FDA approval of Aklief Cream is supported by data from the two pivotal Phase 3 clinical trials of once-daily Aklief Cream in patients with moderate acne on the face and trunk.1 The two identical 12-week, randomized, multicenter, parallel group, double-blind, vehicle-controlled clinical trials of 2,420 patients showed that Aklief Cream significantly reduced inflammatory lesions as early as two weeks on the face and four weeks on the back, shoulders and chest compared to vehicle (p<0.05).1 Aklief Cream was well tolerated when used on the face, back, shoulders and chest.1 The most common adverse reactions (incidence >1%) included application site irritation, application site pruritus (itching) and sunburn.1 

“The approval of Aklief Cream underscores our ability to bring new active molecules to the community, and innovate even in well-established therapeutic classes. It is consistent with our intent to change the paradigm of how even the most common and frustrating skin diseases are treated, including acne,” said Thibaud Portal PhD, Galderma Global Vice President, Prescription. “We are pleased to add this new treatment option, with proven efficacy in facial and truncal acne, to our innovative and differentiated portfolio of acne treatments.”

Aklief Cream is expected to be available in the United States in November 2019. It will be provided in a 45 gram pump. Galderma is working closely with payers, providers and pharmacy benefit managers to ensure broad and rapid access to Aklief Cream. The company will also offer a patient savings card program, Galderma CareConnect*.

*Galderma CareConnect is only available for commercially insured or uninsured patients. Patients who are enrolled in a government-run or government-sponsored healthcare plan with a pharmacy benefit are not eligible to use the Galderma CareConnect Patient Savings Card.

FDA Approves Xcopri (cenobamate) for the Treatment of Partial-Onset Seizures in Adults

 

In continuation of my update on cenobamate

SK Biopharmaceuticals, Co., Ltd., an innovative global pharmaceutical company focused on developing and bringing treatments to market for central nervous system (CNS) disorders, and its U.S. subsidiary SK Life Science, Inc. announced today that the U.S. Food and Drug Administration (FDA) approved Xcopri (cenobamate tablets) as a treatment for partial-onset seizures in adults.

"The approval of Xcopri will provide clinicians with an effective medication for our patients who are continuing to have focal (partial-onset) seizures," said Michael Sperling, MD, Professor of Neurology and Director of the Jefferson Comprehensive Epilepsy Center at the Vickie and Jack Farber Institute for Neuroscience – Jefferson Health in Philadelphia, and an investigator in the Xcopri clinical development program. "It is very encouraging to see that patients receiving Xcopri saw significant reductions in frequency of seizures, with some even achieving zero seizures." 

The approval is based on results from two global, randomized, double-blind, placebo-controlled studies and a large, global, multi-center, open-label safety study that enrolled adults with uncontrolled partial-onset seizures, taking one to three concomitant anti-epileptic drug (AEDs). In the randomized studies (Study 013 and Study 017), Xcopri demonstrated significant reductions in seizure frequency compared to placebo at all doses studied.

"Approximately 3 million adults live with epilepsy in the U.S. and according to the Centers for Disease Control and Prevention (CDC), nearly 60% reported having seizures, even if they took an AED," said Beth Lewin Dean, Chief Executive Officer of Citizens United for Research in Epilepsy (CURE). "There is an urgent need to advance research and introduce new treatment options. The FDA approval of Xcopri for the treatment of partial-onset seizures is a welcome option for the epilepsy community."

The approval also marks the first time a Korean company has independently brought a compound from discovery to U.S. FDA approval.

"Today's approval is a major step toward our goal of becoming a fully-integrated global pharmaceutical company that can discover, develop and deliver new treatment options in epilepsy and CNS," said Jeong Woo Cho, PhD, President and CEO of SK Biopharmaceuticals and SK life science. "We are grateful to the thousands of participants in our trials, clinical investigators, partners in the epilepsy community and our employees for their important contributions in bringing forward this treatment option for adults with partial-onset seizures."

In Study 013, which included a 6-week titration phase followed by a 6-week maintenance phase, a statistically significant 56% reduction in median seizure frequency was seen with Xcopri 200 mg/day (n=113) versus a 22% reduction with placebo (n=108). In Study 017, which included a 6-week titration phase followed by a 12-week maintenance phase, patients randomized to Xcopri 100 mg/day (n=108), 200 mg/day (n=109) or 400 mg/day (n=111) had statistically significant 36%, 55% and 55% reductions in median seizure frequency, respectively, versus a 24% reduction with placebo (n=106). During the maintenance phase of Study 013, a post-hoc analysis showed that 28% of patients receiving Xcopri had zero seizures, compared with 9% of placebo patients. During the maintenance phase of Study 017, 4% of patients in the Xcopri 100 mg/day group, 11% of patients in the Xcopri 200 mg/day group, 21% of patients in the Xcopri 400 mg/day group and 1% of patients in the placebo group reported zero seizures.

Serious reactions associated with Xcopri include drug reaction with eosinophilia and systemic symptoms (DRESS), QT shortening, suicidal behavior and ideation, and neurological adverse reactions. The most common (≥10% and greater than with placebo) treatment-emergent adverse events associated with Xcopri include somnolence (sleepiness), dizziness, fatigue, diplopia (double vision) and headache.

Xcopri is expected to be available in the U.S. in the second quarter of 2020, following scheduling review by the DEA, which typically occurs within 90 days of FDA approval. SK life science is committed to supporting patients taking Xcopri and will introduce a new access program to help patients get started and stay on track with their medicine.

FDA Approves Givlaari (givosiran) for Acute Hepatic Porphyria

Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today that the U.S. Food and Drug Administration (FDA) approved Givlaari (givosiran) injection for subcutaneous use for the treatment of adults with acute hepatic porphyria (AHP). AHP is a family of ultra-rare, genetic diseases characterized by debilitating, potentially life-threatening attacks and, for some patients, chronic manifestations that negatively impact daily functioning and quality of life. Long-term complications of AHP can include chronic neuropathic pain, hypertension, chronic kidney disease and liver disease. Givlaari was shown to significantly reduce the rate of porphyria attacks that required hospitalizations, urgent healthcare visits or IV hemin administration at home.

“We believe the approval of Givlaari represents a landmark event for the advancement of precision genetic medicines, providing new hope for patients and their caregivers living with the debilitating manifestations of AHP and unpredictable nature of AHP attacks, as well as for the doctors who diagnose and treat these patients. We are grateful to the investigators, patients and families who have helped make this new treatment option a reality for the AHP community. We also commend the FDA for recognizing the immense medical need and granting this approval so quickly,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “Givlaari now becomes our second RNAi therapeutic to be approved in the last 16 months, and the world’s first-ever GalNAc-conjugate RNA therapeutic to be approved, representing a watershed moment for a technology uniquely pioneered by Alnylam scientists. We believe today’s news reinforces the promise and potential of RNAi therapeutics as a whole new class of medicines and brings us one important step closer to fulfilling our Alnylam 2020 goals of building a multi-product, global commercial company with a deep clinical pipeline to drive growth and an organic product engine to fuel sustainable innovation.”

The FDA approval of Givlaari was received in less than four months after acceptance of the NDA, and was based on positive results from the ENVISION Phase 3 study, a randomized, double-blind, placebo-controlled, multinational study of 94 patients with AHP, at 36 study sites in 18 countries – the largest ever interventional study conducted in AHP. In ENVISION, AHP patients on Givlaari experienced 70% (95% CI: 60%, 80%) fewer porphyria attacks compared to placebo. Givlaari also resulted in a similar reduction in intravenous hemin use, as well as reductions in urinary aminolevulinic acid (ALA), and urinary porphobilinogen (PBG).

In the pivotal ENVISION study, the most common adverse reactions (reported in at least 20% of patients) with Givlaari were nausea (27%) and injection site reactions (25%). Other adverse reactions seen in patients treated with Givlaari (occurring over 5% more frequently than placebo) include rash, serum creatinine increase, transaminase elevations and fatigue. As previously reported, one patient in the Givlaari clinical development program experienced an anaphylactic reaction which resolved with medical management.

“Adults with AHP now have a new treatment option that has demonstrated the ability to reduce the frequency of porphyria attacks by specifically addressing factors associated with attacks and other disease manifestations of AHP,” said Manisha Balwanii, M.D., M.S, Associate Professor of the Department of Genetics and Genomic Sciences and Department of Medicine at the Icahn School of Medicine at Mount Sinai and principal investigator of the ENVISION study. “With the approval of Givlaari, and based on the efficacy data from the ENVISION study, I hope to see my patients and those across the country be able to live more normal lives with fewer porphyria attacks.”

“The FDA approval of Givlaari is an important milestone for our community, as we now have a new treatment option for adults living with acute hepatic porphyria,” said Kristen Wheeden, Executive Director, American Porphyria Foundation. “AHP can have a profound impact on the lives of patients and their families. Porphyria attacks are associated with severe, incapacitating pain, often requiring hospitalization for management. In addition, many patients struggle on a daily basis with chronic symptoms related to their disease. The approval of Givlaari is exciting for our community.”

Alnylam is committed to helping people access the medicines they are prescribed and will be offering comprehensive support services for people prescribed Givlaari through Alnylam Assist®. Visit AlnylamAssist.com for more information or call 1-833-256-2748.

Givlaari is expected to be available for shipment to healthcare providers in the U.S. by year-end. HCPs can initiate the process now by visiting www.AlnylamAssist.com and completing and submitting a Start Form.

In August, Alnylam announced a U.S. gastrointestinal (GI) disease education and promotional agreement for Givlaari with Ironwood Pharmaceuticals, Inc., a GI healthcare company. Under the agreement, Alnylam will leverage Ironwood’s leading capabilities in GI to help raise awareness of AHP among gastroenterologists and other healthcare practitioners in the U.S. Ironwood will also participate in Givlaari promotional efforts, augmenting Alnylam’s broader commercialization activities.

FDA Approves Fetroja (cefiderocol) for the Treatment of Complicated Urinary Tract Infections

The U.S. Food and Drug Administration approved Fetroja (cefiderocol), an antibacterial drug for treatment of patients 18 years of age or older with complicated urinary tract infections (cUTI), including kidney infections caused by susceptible Gram-negative microorganisms, who have limited or no alternative treatment options.

“Today’s approval provides an additional treatment option for patients with cUTIs who have limited or no alternative treatment options,” said John Farley, M.D., M.P.H., acting director of the Office of Infectious Diseases in the FDA’s Center for Drug Evaluation and Research. “A key global challenge the FDA faces as a public health agency is addressing the threat of antimicrobial-resistant infections, like cUTIs. This approval represents another step forward in the FDA’s overall efforts to ensure safe and effective antimicrobial drugs are available to patients for treating infections.”

The safety and effectiveness of Fetroja was demonstrated in a study of 448 patients with cUTIs. Of the patients who were administered Fetroja, 72.6% had resolution of symptoms and eradication of the bacteria approximately seven days after completing treatment, compared with 54.6% in patients who received an alternative antibiotic. The clinical response rates were similar between the two treatment groups.

Labeling for Fetroja includes a warning regarding the higher all-cause mortality rate observed in Fetroja-treated patients compared to those treated with other antibiotics in a trial in critically ill patients with multidrug-resistant Gram-negative bacterial infections. The cause of the increase in mortality has not been established. Some of the deaths were a result of worsening or complications of infection, or underlying co-morbidities. The higher all-cause mortality rate was observed in patients treated for hospital-acquired/ventilator-associated pneumonia (i.e.nosocomial pneumonia), bloodstream infections, or sepsis. The safety and efficacy of Fetroja has not been established for the treatment of these types of infections.

The most common adverse reactions observed in patients treated with Fetroja included diarrhea, constipation, nausea, vomiting, elevations in liver tests, rash, infusion site reactions, candidiasis (yeast infection), cough, headache and hypokalemia (low potassium). Fetroja should not be used in individuals with a known history of severe hypersensitivity to beta-lactam antibacterial drugs.

Fetroja received the FDA’s Qualified Infectious Disease Product (QIDP) designation. The QIDP designation is given to antibacterial and antifungal drug products intended to treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. As part of QIDP designation, Fetroja was granted Priority Review under which the FDA’s goal is to take action on an application within an expedited time frame.

FDA Approves Brukinsa (zanubrutinib) for the Treatment of Mantle Cell Lymphoma

BeiGene, Ltd.,  a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer,  announced that Brukinsa (zanubrutinib) has received accelerated approval from the United States Food and Drug Administration (FDA) as a treatment for mantle cell lymphoma (MCL) in adult patients who have received at least one prior therapy. Brukinsa is the first BeiGene-discovered product to be approved, an important milestone toward the company’s goal of transforming treatment for cancer patients around the world. 

This accelerated approval is based on overall response rate (ORR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

“We are working to improve outcomes for people with cancer worldwide and this approval brings us closer to realizing our mission of bringing the highest quality therapies to patients globally,” said John V. Oyler, Chairman, Co-Founder, and CEO of BeiGene. “Today’s FDA approval of Brukinsa, following the previously granted Breakthrough Therapy designation in this indication, validates it as an important treatment option for people with relapsed or refractory MCL. We hope this is the first of many approvals for Brukinsa as we continue to evaluate its potential in other hematologic cancers.”

“Brukinsa is a BTK inhibitor that was designed to maximize target occupancy and minimize off-target binding. It entered the clinic in 2014 and since that time our broad development program has enrolled more than 1,600 patients globally,” said Jane Huang, M.D., Chief Medical Officer, Hematology at BeiGene. “Today’s accelerated approval is the culmination of many years of effort by the BeiGene team, the dedicated investigators involved in these trials and, most importantly, the patients who participated by enrolling in the clinical trials. We are humbled by the opportunity to develop this therapy and launch it as our first internally discovered and approved cancer treatment.”

“BTK inhibition is an established mode of treatment for patients with MCL, but many patients treated with previously approved BTK inhibitors do not fully respond to BTK therapy or are forced to discontinue treatment early due to side effects. Today we have a new option for our adult patients who have received one prior systemic or targeted therapy and are living with MCL, an aggressive blood cancer that’s often diagnosed at a more advanced stage,” said Luhua (Michael) Wang, M.D., Professor, Department of Lymphoma and Myeloma, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center, and clinical trial investigator.

“The approval of Brukinsa as a second line therapy represents an important advancement for the treatment of mantle cell lymphoma,” said Meghan Gutierrez, Chief Executive Officer for the Lymphoma Research Foundation. “Expanded treatment options can transform the patient experience and provide hope to people living with a mantle cell diagnosis.”

The FDA’s approval of Brukinsa is based on efficacy results from two single-arm clinical trials, with independent review committee (IRC)-assessed ORR per 2014 Lugano Classification as the primary endpoint. Across both trials, Brukinsa achieved an ORR, which is the sum of complete responses and partial responses, of 84%.

In the multicenter Phase 2 trial of zanubrutinib in patients with relapsed or refractory (R/R) MCL BGB-3111-206 (NCT03206970), the ORR was 84% (95% CI: 74%, 91%), including 59% complete response (FDG-PET scan required) and 24% partial response. In this study, the median duration of response (DOR) was 19.5 months (95%CI: 16.6, NE) and median follow-up time on study was 18.4 months. In the global Phase 1/2 trial BGB-3111-AU-003  (NCT02343120), the ORR was 84% (95% CI: 67%, 95%), including 22% complete response (FDG-PET scan not required) and 62% partial response. In this study, the median DOR was 18.5 months1 (95% CI:12.6, NE) and median follow-up time on study was 18.8 months.

The most common adverse reactions (> 10%) with Brukinsa were decreased neutrophil count, decreased platelet count, upper respiratory tract infection, decreased white blood cell count, decreased hemoglobin, rash, bruising, diarrhea, cough, musculoskeletal pain, pneumonia, urinary tract infection, blood in the urine (hematuria), fatigue, constipation, and hemorrhage. The most frequent serious adverse reactions were pneumonia (11%) and hemorrhage (5%).

Of the 118 patients with MCL treated with Brukinsa, eight (7%) patients discontinued treatment due to adverse reactions in the trials. The most frequent adverse reaction leading to treatment discontinuation was pneumonia (3.4%). One (0.8%) patient experienced an adverse reaction leading to dose reduction (hepatitis B).

FDA Approves Reblozyl (luspatercept-aamt) for the Treatment of Anemia in Adults With Beta Thalassemia Who Require Regular Red Blood Cell Transfusions

In continuation of my update on Luspatercept 

Celgene Corporation (NASDAQ: CELG) and Acceleron Pharma Inc. (NASDAQ: XLRN) today announced the U.S. Food and Drug Administration (FDA) has approved Reblozyl (luspatercept-aamt) for the treatment of anemia in adult patients with beta thalassemia who require regular red blood cell (RBC) transfusions. Reblozyl is not indicated for use as a substitute for RBC transfusions in patients who require immediate correction of anemia. Reblozyl is the first and only FDA-approved erythroid maturation agent, representing a new class of therapy which works by regulating late-stage red blood cell maturation to help patients reduce their RBC transfusion burden.

“Today’s approval is an important milestone and underscores our continued commitment to patients with hematology disorders,” said Nadim Ahmed, President, Global Hematology and Oncology for Celgene. “There are very limited options for patients living with anemia due to beta thalassemia who are dependent on long term red blood cell transfusions. We are pleased to make Reblozyl available as a new therapy for these patients to help address their anemia, a significant clinical complication of beta thalassemia.”

“We’re thrilled that Acceleron’s first approved medicine is one with the potential to help patients with beta thalassemia, who have been in need of new treatments for this lifelong disease,” said Habib Dable, President and Chief Executive Officer of Acceleron. “We are enormously grateful to the patients, families and caregivers who participated in and supported our research. Their contributions have been essential in helping to ensure that Reblozyl would emerge successfully from our longstanding collaboration with Celgene.”

Beta thalassemia is a rare, inherited blood disorder caused by a genetic defect in hemoglobin. The disease is associated with ineffective erythropoiesis, which results in the production of fewer and less healthy RBCs, often leading to severe anemia – a condition that can be debilitating and can lead to more severe complications for patients – as well as other serious health issues. Treatment options for anemia associated with beta thalassemia are limited, consisting mainly of RBC transfusions, which have the potential to contribute to iron overload, which can cause serious complications such as organ damage.

The approval of Reblozyl for beta thalassemia, which received a Priority Review designation from the FDA, is based on results from the pivotal, Phase 3, randomized, double-blind, placebo-controlled, multicenter BELIEVE trial evaluating the safety and efficacy of Reblozyl for the treatment of anemia in adult patients with beta thalassemia who require regular RBC transfusions (defined as 6-20 RBC units per 24 weeks, with no transfusion-free period greater than 35 days during that period). All patients were eligible to receive best supportive care, which included RBC transfusions; iron-chelating agents; use of antibiotic, antiviral, and antifungal therapy; and/or nutritional support, as needed. The trial achieved a clinically meaningful and statistically significant improvement in the primary endpoint. In the Reblozyl arm, 21.4% of patients (n=48) achieved a ≥33% reduction from baseline in RBC transfusion burden (with a reduction of at least 2 units) during weeks 13–24 after randomization, compared to 4.5% (n=5) in the placebo arm (risk difference [95% CI]: 17.0 [10.4, 23.6], P<0.0001).

The study also met key secondary endpoints, including transfusion burden reduction of at least 33% (with a reduction of at least 2 units), during weeks 37 to week 48, which was achieved in 19.6% (n=44) of patients in the Reblozyl arm and 3.6% (n=4) in the placebo arm (risk difference [95% CI]: 16.1 [9.8, 22.4], P<0.0001).

Other efficacy endpoints included transfusion burden reduction of ≥50% (with a reduction of at least 2 units) during weeks 13-24 and weeks 37-48.1 A ≥50% reduction in transfusion burden was observed in 7.6% of patients (n=17) receiving Reblozyl vs. 1.8% of patients (n=2) in the placebo arm at weeks 13-24 (risk difference [95% CI]: 5.8 [1.6, 10.1], P=0.0303), and 10.3% of patients (n=23) vs. 0.9% of patients (n=1) at weeks 37-48 (risk difference [95% CI]: 9.4 [5, 13.7], P=0.0017), respectively.

In the BELIEVE trial, thromboembolic events, including deep vein thromboses, pulmonary embolus, portal vein thrombosis, and ischemic stroke, were experienced in 3.6% (8/223) of Reblozyl treated patients.1 Hypertension was reported in 10.7% (61/571) of Reblozyl-treated patients across the clinical development program.1 Reblozyl may cause fetal harm when administered to a pregnant woman. Serious adverse reactions occurred in 3.6% of patients receiving Reblozyl.1 Serious adverse reactions reported in 1% of patients were cerebrovascular accident and deep vein thrombosis.1 One patient died due to an unconfirmed case of AML.1 The most common adverse reactions (at least 10% for Reblozyl, and 1% more than placebo) were headache (26% vs 24%), bone pain (20% vs 8%), arthralgia (19% vs 12%), fatigue (14% vs 13%), cough (14% vs 11%), abdominal pain (14% vs 12%), diarrhea (12% vs 10%) and dizziness (11% vs 5%).

Permanent discontinuation due to an adverse reaction (Grades 1-4) occurred in 5.4% of patients who received Reblozyl.1 The most frequent adverse reactions requiring permanent discontinuation in patients who received Reblozyl included arthralgia (1%), back pain (1%), bone pain (<1%), and headache (<1%).1 Dosage reductions due to an adverse reaction occurred in 2.7% of patients who received Reblozyl.1 The most frequent adverse reactions requiring a dosage reduction in >0.5% of patients who received Reblozyl included hypertension and headache.1 Dosage interruptions due to an adverse reaction occurred in 15.2% of patients who received Reblozyl.1 The most frequent adverse reactions requiring a dosage interruption in >1% of patients who received Reblozyl included upper respiratory tract infection, ALT increase, and cough.
