FDA Accepts Correvio's Resubmitted New Drug Application for Brinavess (vernakalant)

In continuation of my update on vernakalant 

Correvio Pharma Corp. (CORV) (CORV), a specialty pharmaceutical company focused on commercializing hospital drugs, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the resubmitted New Drug Application (NDA) for Brinavess™ (vernakalant hydrochloride, IV), an antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation (AF) to sinus rhythm in adult patients.  The FDA assigned a target action date of December 24, 2019 under the Prescription Drug User-Fee Act (PDUFA).  In its acceptance letter, the FDA stated that it is currently planning to hold an advisory committee meeting to discuss this application.

"The FDA's acceptance of this resubmitted NDA marks another important milestone for Correvio and for the global Brinavess program," said Mark H.N. Corrigan, MD, CEO of Correvio.  "As a potential new AF treatment, with a well-characterized efficacy and safety profile, we believe that Brinavess, if approved, will be an attractive addition to the AF treatment landscape.  We look forward to working with the FDA during the review process."

The Company also announced certain preliminary financial results for the second quarter ended June 30, 2019.  Revenue for the second quarter is expected to be in the range of $7.2 to 7.6 million (USD), which represents an approximately 20% increase compared to the second quarter of 2018, despite 5% weakness in the Euro.  As of June 30, 2019, Correvio had cash, cash equivalents and unrestricted cash totalling approximately $12.9 million (USD).  The Company will report its full financial results in August.

The Brinavess NDA is supported by data from SPECTRUM, a post-authorization safety study that was conducted in Europe which evaluated 1,778 unique patients across a total of 2,009 treatment episodes following administration of Brinavess.  The SPECTRUM data demonstrated that treatment with Brinavess successfully converted 70.2% of those treated AF patients into normal sinus rhythm.  In addition, treatment with Brinavess showed a median time to conversion of 11 minutes from the start of the first infusion among patients who successfully converted.  The cumulative incidence of health outcomes of interest (defined as significant hypotension, ventricular arrhythmia, atrial flutter, or bradycardia) was reported in 0.8% of patients.  Twenty-eight serious adverse events were reported in 26 of the 1,778 patients and no deaths were reported in the study.  In addition to SPECTRUM, the Brinavess NDA is supported by nine Phase 3 and Phase 2 clinical trials and over eight years of post-marketing experience in approximately 50,000 treatment patients worldwide.  Brinavess has received marketing authorizations in 41 countries outside the U.S.

About Atrial Fibrillation

Atrial Fibrillation (also known as AFib or AF) is a supraventricular tachyarrhythmia with uncoordinated atrial activation resulting in ineffective atrial contraction and if left untreated, structural and/or electrophysiological atrial tissue abnormalities. AF is a common cardiac rhythm disturbance that increases in prevalence with advancing age. According to the American Heart Association, estimates of the prevalence of AF in the U.S. ranged from 2.7 million to 6.1 million in 2010, and is expected to rise to between 5.6 million to 12 million in 2030.

There are two strategies to manage AF, namely, rhythm- or rate-control. A rhythm-control strategy may be used in patients who are severely compromised, remain symptomatic despite adequate rate control, when adequate rate control is difficult to achieve, when long term rhythm control therapy is preferred, younger patient age, presence of tachycardia-mediated cardiomyopathy, and first episode of AF. Early intervention with a rhythm-control strategy to prevent progression of AF may be particularly beneficial to the AF patient.

About Brinavess

Brinavess (vernakalant HCl, IV) is an antiarrhythmic drug that acts preferentially in the atria by prolonging atrial refractoriness and slowing impulse conduction in a rate-dependent fashion. Brinavess is approved for marketing in Europe, Canada and several other countries worldwide. In Europe, it is approved for the rapid conversion of recent onset atrial fibrillation to sinus rhythm in adults: 1) for non-surgery patients: atrial fibrillation < 7 days duration; and 2) for post-cardiac surgery patients: atrial fibrillation <3 days duration. Vernakalant IV is not approved for use in the United States.

Epizyme Announces FDA Filing Acceptance of New Drug Application and Priority Review for Tazemetostat for the Treatment of Epithelioid Sarcoma

Epizyme, Inc. (Nasdaq: EPZM), a late-stage biopharmaceutical company developing novel epigenetic therapies, today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing the company’s New Drug Application (NDA) for accelerated approval of tazemetostat, its lead investigational agent. Epizyme has proposed an indication of metastatic or locally advanced epithelioid sarcoma not eligible for curative surgery. The FDA granted Priority Review for the NDA and has set a Prescription Drug User Fee Act (PDUFA) target action date of January 23, 2020. Priority Review is granted to investigational therapies that, if approved, may offer significant improvements in the treatment, prevention or diagnosis of a serious condition.

“We are thrilled with FDA’s acceptance of this first tazemetostat NDA submission for priority review, and to be an important step closer to achieving our mission of rewriting treatment for patients with cancer and other serious diseases,” said Robert Bazemore, president and chief executive officer of Epizyme. “This is a significant achievement in the development of this potentially first-in-class EZH2 inhibitor, and we look forward to working with FDA during the review. If approved, we believe tazemetostat could become an important new option in the treating physicians’ arsenal. We would like to extend our sincerest gratitude to those patients, families and medical teams who have participated in our clinical studies and helped bring tazemetostat to this stage.”

Epizyme’s NDA submission is based primarily on data from the 62 patient epithelioid sarcoma cohort of its ongoing Phase 2 study of tazemetostat. These data, recently reported at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting, showed that tazemetostat treatment resulted in clinically meaningful and durable responses, and was generally well-tolerated.

To support full approval of tazemetostat for epithelioid sarcoma, Epizyme will initiate a global confirmatory trial. The company plans to conduct a 1:1 randomized, controlled clinical trial in the front-line treatment setting comparing tazemetostat in combination with doxorubicin versus placebo plus doxorubicin in approximately 150 patients. The primary efficacy endpoint will be progression-free survival, and secondary efficacy endpoints will include overall survival, disease control rate, overall response rate and duration of response. The confirmatory study will include a safety run-in that is expected to begin in the second half of 2019.

About the Tazemetostat Clinical Trial Program 

Tazemetostat, an oral, potent, first-in-class EZH2 inhibitor, is currently being studied as a monotherapy in ongoing clinical programs in patients with certain molecularly defined solid tumors, including epithelioid sarcoma and other INI1-negative tumors, and in patients with follicular lymphoma, both with and without EZH2 activating mutations. Multiple clinical studies are underway through collaborations assessing tazemetostat as a combination treatment for patients with diffuse large B-cell lymphoma. Epizyme also plans to conduct multiple additional clinical trials designed to evaluate the potential benefit of tazemetostat in earlier lines of therapy for follicular lymphoma, as well as new combinations and cancer indications.

Sunovion Announces Acceptance by the U.S. FDA of the New Drug Application for Dasotraline for the Treatment of Adults with Moderate-to-Severe Binge Eating Disorder

In continuation of my update on dasotraline,

Sunovion Pharmaceuticals Inc.(Sunovion) today announced that the U.S. Food and Drug Administration (FDA) has accepted its New Drug Application (NDA) for dasotraline, a novel dopamine and norepinephrine reuptake inhibitor (DNRI), for the treatment of patients with moderate-to-severe binge eating disorder (BED). Dasotraline’s pharmacokinetic profile, characterized by an extended half-life, supports its potential for sustained control of moderate-to-severe BED symptoms.

The action date by the FDA under the Prescription Drug User Fee Act (PDUFA) is May 14, 2020.

Dasotraline is an investigational, once-daily medication that demonstrated significant efficacy for the treatment of moderate-to-severe BED in two 12-week, randomized, placebo-controlled studies, SEP360-221 and SEP360-321. Dasotraline was found to be generally well tolerated in clinical studies, including a long-term safety study, SEP360-322, that assessed patients with moderate-to-severe BED for up to one year.

“Binge eating disorder is a serious mental health condition for which limited treatment options exist. The disorder is often seen in association with other behavioral conditions such as depression, substance abuse and post-traumatic stress disorder, and it is often under-diagnosed and under-treated,” said Antony Loebel, M.D., President and Chief Executive Officer at Sunovion. “We are confident in the value dasotraline has shown in clinical trials to people living with BED and look forward to working with the FDA to advance this novel treatment option.”

According to the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5),2,3 BED is characterized by recurrent and persistent episodes of binge eating, defined as consuming large quantities of food in a short period of time, perception of loss of control during the episode, and intense feelings of shame, guilt and embarrassment afterwards. Many individuals also suffer from depressive and anxiety symptoms, as well as a number of medical complications, leading to impaired functioning and quality of life.

Blueprint Medicines Announces FDA Acceptance of New Drug Application for Avapritinib for the Treatment of PDGFRA Exon 18 Mutant GIST and Fourth-Line GIST

Blueprint Medicines Corporation (NASDAQ: BPMC), a precision therapy company focused on genomically defined cancers, rare diseases and cancer immunotherapy, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company's New Drug Application (NDA) for avapritinib for the treatment of adult patients with PDGFRA Exon 18 mutant gastrointestinal stromal tumors (GIST), regardless of prior therapy, and fourth-line GIST. The FDA granted Priority Review and set an action date of February 14, 2020 under the Prescription Drug User Fee Act (PDUFA). At this time, the FDA is not planning to hold an advisory committee meeting to discuss this application. Avapritinib, an investigational therapy, is a potent and highly selective KIT and PDGFRA inhibitor for patients with advanced GIST.

"Patients with PDGFRA Exon 18 mutant GIST and fourth-line GIST are in need of new treatment options that address the underlying drivers of the disease," said Andy Boral, M.D., Ph.D., Chief Medical Officer at Blueprint Medicines. "The FDA's acceptance of our application for Priority Review brings us closer to our goal of delivering avapritinib to patients with GIST, and we look forward to working closely with the FDAduring the review process."

The FDA's acceptance of the NDA indicates the application is sufficiently complete to permit a substantive review. A Priority Review designation accelerates the FDA's review time from 12 months to a goal of eight months from the NDA submission date, and is granted to drugs that may offer a significant improvement in the safety or effectiveness of the treatment, prevention or diagnosis of a serious condition. Previously, the FDA granted avapritinib Breakthrough Therapy Designation for the treatment of patients with unresectable or metastatic GIST harboring the PDGFRα D842V mutation.

In July 2019, the European Medicines Agency validated Blueprint Medicines' Marketing Authorization Application for avapritinib in adult patients with PDGFRα D842V mutant GIST, regardless of prior therapy, and fourth-line GIST.

About GIST

GIST is a sarcoma, or tumor of bone or connective tissue, of the gastrointestinal (GI) tract. Tumors arise from cells in the wall of the GI tract and occur most often in the stomach or small intestine. Most patients are diagnosed between the ages of 50 to 80, and diagnosis is typically triggered by GI bleeding, incidental findings during surgery or imaging and, in rare cases, tumor rupture or GI obstruction.

Most GIST cases are caused by a spectrum of clinically relevant mutations that force the KIT or PDGFRA protein kinases into an increasingly active state. Because currently available therapies primarily bind to the inactive protein conformations, certain primary and secondary mutations typically lead to treatment resistance and disease progression.

In unresectable or metastatic GIST, clinical benefits from existing treatments can vary by mutation type. Mutational testing is critical to tailor therapy to the underlying disease driver and is recommended in expert guidelines. Currently, there are no approved therapies for patients with KIT-driven GIST whose disease progresses beyond imatinib, sunitinib and regorafenib. In patients with metastatic PDGFRα D842V-driven GIST, progression occurs in a median of approximately three to four months with available therapy.

AbbVie's HIV Drug Aluvia (Lopinavir/ritonavir) Seen as Potential Treatment for Coronavirus

In continuation of my update on Lopinavir/Fritonavior

 

More than 80 people have died from the coronavirus in China. The Chinese government is turning to a drug developed by AbbVie for HIV patients as a potential treatment for the outbreak that has reached the shores of the United States.

AbbVie said it was donating more than one million dollars’ worth of Aluvia, a combination of lopinavir and ritonavir as an ad-hoc treatment for pneumonia that is associated with the outbreak. The Chinese government suggested last week that taking two lopinavir/ritonavir pills and inhaling a dose of nebulized alpha-interferon twice a day could benefit these patients, Reuters reported. There are more than 2,000 known cases of the coronavirus in China. The illness has caused parts of China to grind to a halt as health officials seek to contain the spread of the virus.

The decision to use AbbVie’s medicine came after a noted respiratory expert at Peking University First Hospital in Beijing said he was given the HIV drugs to fight the virus after he contracted it following a visit to Wuhan, the capital of Hubei province in central China where the virus is thought to have originated. Wan Guangfa came down with the virus after interacting with coronavirus patients. He told China News Week that the HIV treatments worked for him.

The coronavirus family includes the common cold as well as viruses that cause more serious illnesses, such as SARS that spread from China to more than a dozen countries in 2002-03 and killed about 800 people. Also, the virus is similar to Middle Eastern Respiratory Syndrome (MERS), which developed from camels. The virus infects the lungs, and symptoms start with a fever and cough. It can progress to shortness of breath and breathing difficulties leading to pneumonia.

Aluvia is thought to be a potential treatment for the coronavirus due to its ability to block a protease that the virus needs to replicate within the human body. AbbVie’s drug has previously been tested in patients with SARS and MERS, which are similar viruses, Endpoints reported.

Other drugmakers are also responding. Gilead Sciences is looking at its Ebola virus drug remdesivir, an antiviral, as a potential coronavirus treatment, The Motley Fool reported. Moderna also has a treatment for the virus under investigation. The company received a grant from the Coalition for Epidemic Preparedness Innovations to investigate a treatment for the virus. Inovio also received a grant from CEPI to develop a potential vaccine.

FDA Approves Inrebic (fedratinib) for the Treatment of Patients With Myelofibrosis

Celgene Corporation (NASDAQ: CELG)  announced the U.S. Food and Drug Administration (FDA) approval of  Inrebic (fedratinib) for the treatment of adult patients with intermediate-2 or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis.1

“The approval of Inrebic is another important milestone for Celgene and underscores our commitment to people living with blood cancers,” said Jay Backstrom, M.D., M.P.H., Chief Medical Officer for Celgene. “We are excited to provide Inrebic as a new treatment option that may be used in patients with myelofibrosis, including patients previously treated with ruxolitinib.”

“Myelofibrosis can cause patients to suffer in many ways, including experiencing debilitating symptoms,” said Ruben Mesa, M.D., FACP, Director of the Mays Cancer Center at UT Health San Antonio Cancer Center MD Anderson. “There has not been a new treatment approved for this disease in nearly a decade. With Inrebic, physicians and patients now have another option available for myelofibrosis.”

The Inrebic development program consisted of multiple studies (including JAKARTA and JAKARTA2) in 608 patients who received more than one dose (ranging from 30 mg to 800 mg),1 of whom 459 had myelofibrosis,1 including 97 previously treated with ruxolitinib.1 The JAKARTA study evaluated the efficacy and safety of once-daily oral doses of Inrebic compared with placebo in patients with intermediate-2 or high-risk, primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis who were previously untreated with a JAK inhibitor, had enlarged spleens (a condition known as splenomegaly), and had a platelet count of ≥50 x 109/L (median baseline platelet count was 214 x 109/L; 16% <100 x 109/L and 84% ≥100 x 109/L).1,2 In the JAKARTA study, spleen volume was reduced by 35% or greater, when assessed from baseline to the end of cycle 6 (week 24), with a 4-week follow-up scan, in 37% (35 of 96) of patients treated with INREBIC 400 mg versus 1% (1 of 96) of patients who received placebo (p<0.0001).1 INREBIC also improved the Total Symptom Score as measured by the modified Myelofibrosis Symptoms Assessment Form (MFSAF) v2.0 diary2 (night sweats, itching, abdominal discomfort, early satiety, pain under ribs on left side, bone or muscle pain) by 50% or greater when assessed from baseline to the end of cycle 6 in 40% of (36 of 89) patients treated with 400 mg, versus 9% (7 of 81) of patients who received placebo (p<0.0001).1

Inrebic has a Boxed Warning for serious and fatal encephalopathy, including Wernicke’s. Serious encephalopathy was reported in 1.3% (8 of 608) of patients treated with Inrebic in clinical trials and 0.16% (1 of 608) of the cases were fatal. Wernicke’s encephalopathy is a neurologic emergency resulting from thiamine (Vitamin B1) deficiency. Thiamine levels should be assessed in all patients prior to starting Inrebic, periodically during treatment, and as clinically indicated.1 Do not start Inrebic in patients with thiamine deficiency; replete thiamine prior to treatment initiation. If encephalopathy is suspected, immediately discontinue Inrebic and initiate parenteral thiamine. Monitor until symptoms resolve or improve and thiamine levels normalize.

In the JAKARTA study, serious adverse reactions occurred in 21% of patients treated with Inrebic 400 mg once daily (n=96), with the most common (≥2%) being cardiac failure (5%) and anemia (2%).1 Fatal adverse reactions of cardiogenic shock occurred in 1% of patients.1 Permanent discontinuation due to an adverse reaction occurred in 14% of patients. The most frequent reasons for permanent discontinuation in ≥2% of patients receiving Inrebic included cardiac failure (3%), thrombocytopenia, myocardial ischemia, diarrhea, and increased blood creatinine (2% each).1

Dosage interruptions due to an adverse reaction during the randomized treatment period occurred in 21% of patients who received Inrebic. Adverse reactions requiring dosage interruption in >3% of patients who received Inrebic included diarrhea and nausea. Dosage reductions due to an adverse reaction during the randomized treatment period occurred in 19% of patients who received Inrebic. Adverse reactions requiring dosage reduction in >2% of patients who received Inrebic included anemia (6%), diarrhea (3%), vomiting (3%), and thrombocytopenia (2%).

“Inrebic is a much-welcomed new treatment for the myelofibrosis community,” said Ann Brazeau, Chief Executive Officer and Founder, MPN Advocacy and Education International. “This FDA approval marks an important milestone for people living with myelofibrosis as we embark on making greater strides in the diagnosis, understanding and treatment of this disease.”

FDA Approves Eylea (aflibercept) Injection Prefilled Syringe

Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN)  announced the U.S. Food and Drug Administration (FDA)   approval the Chemistry, Manufacturing and Controls (CMC) Prior-Approval Supplement (PAS) for the Eylea (aflibercept) Injection prefilled syringe. The 2 mg, single-dose, sterilized prefilled syringe provides physicians with a new way to administer Eylea that requires fewer preparation steps compared to vials. Market supply of the Eylea prefilled syringe is expected to be available to physicians and patients this year.

"With eight pivotal Phase 3 trials and millions of injections used around the world, Eylea sets a high bar for visual acuity and safety across multiple retinal diseases, including wet age-related macular degeneration and diabetic eye diseases," said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer of Regeneron. "This approval may help doctors more conveniently and efficiently deliver Eylea to appropriate patients."

The sterilized prefilled syringe offers the same medicine as the currently available Eylea, in an easier to use and administer presentation.

In the U.S., Eylea is indicated to treat neovascular (wet) age-related macular degeneration (Wet AMD), macular edema following retinal vein occlusion (RVO), diabetic macular edema (DME) and diabetic retinopathy (DR).

About Eylea (aflibercept) Injection

Eylea (aflibercept) Injection is a vascular endothelial growth factor (VEGF) inhibitor formulated as an injection for the eye. It is designed to block the growth of new blood vessels and decrease the ability of fluid to pass through blood vessels (vascular permeability) in the eye by blocking VEGF-A and placental growth factor (PLGF), two growth factors involved in angiogenesis. In the U.S., Eylea is the market-leading, FDA-approved anti-VEGF treatment for its approved indications and is supported by a robust body of research that includes eight pivotal Phase 3 trials.

IMPORTANT SAFETY INFORMATION

• Eylea (aflibercept) Injection is contraindicated in patients with ocular or periocular infections, active intraocular inflammation, or known hypersensitivity to aflibercept or to any of the excipients in Eylea.
• Intravitreal injections, including those with Eylea, have been associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering Eylea. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately. Intraocular inflammation has been reported with the use of Eylea.
• Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection, including with Eylea. Sustained increases in intraocular pressure have also been reported after repeated intravitreal dosing with VEGF inhibitors. Intraocular pressure and the perfusion of the optic nerve head should be monitored and managed appropriately.
• There is a potential risk of arterial thromboembolic events (ATEs) following intravitreal use of VEGF inhibitors, including Eylea. ATEs are defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause). The incidence of reported thromboembolic events in wet AMD studies during the first year was 1.8% (32 out of 1824) in the combined group of patients treated with Eylea compared with 1.5% (9 out of 595) in patients treated with ranibizumab; through 96 weeks, the incidence was 3.3% (60 out of 1824) in the Eylea group compared with 3.2% (19 out of 595) in the ranibizumab group. The incidence in the DME studies from baseline to week 52 was 3.3% (19 out of 578) in the combined group of patients treated with Eylea compared with 2.8% (8 out of 287) in the control group; from baseline to week 100, the incidence was 6.4% (37 out of 578) in the combined group of patients treated with Eylea compared with 4.2% (12 out of 287) in the control group. There were no reported thromboembolic events in the patients treated with Eylea in the first six months of the RVO studies.
• Serious adverse reactions related to the injection procedure have occurred in <0.1% of intravitreal injections with Eylea including endophthalmitis and retinal detachment.
• The most common adverse reactions (≥5%) reported in patients receiving Eylea were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and intraocular pressure increased.

INDICATIONS

Eylea (aflibercept) Injection 2 mg (0.05 mL) is indicated for the treatment of patients with Neovascular (Wet) Age-related Macular Degeneration (AMD), Macular Edema following Retinal Vein Occlusion (RVO), Diabetic Macular Edema (DME), and Diabetic Retinopathy (DR).

FDA Approves Rinvoq (upadacitinib), an Oral JAK Inhibitor for the Treatment of Moderate to Severe Rheumatoid Arthritis

In continuation of my update on Rinvoq (upadacitinib)

AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has approved Rinvoq (upadacitinib), a 15 mg, once-daily oral Janus kinase (JAK) inhibitor, for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response or intolerance to methotrexate (MTX-IR).1 Rinvoq is expected to be available in the U.S. in late August 2019.

The FDA approval of Rinvoq is supported by data from the SELECT program, one of the largest registrational Phase 3 programs in RA with approximately 4,400 patients evaluated across all treatment arms in five studies.2-6 The studies include assessments of efficacy, safety and tolerability across a variety of RA patients, including those who failed or were intolerant to biologic disease-modifying anti-rheumatic drugs and who were naïve or inadequate responders to methotrexate. Rinvoq is not indicated for methotrexate-naïve patients.

"Despite the availability of multiple treatment options with varying mechanisms of action, many patients still do not achieve clinical remission or low disease activity—the primary treatment goals for rheumatoid arthritis," said Roy M. Fleischmann, M.D., primary investigator for SELECT-COMPARE and clinical professor at the University of Texas Southwestern Medical Center at Dallas. "With this FDA approval, Rinvoq has the potential to help additional people living with RA achieve remission who have not yet reached this goal."

Across the SELECT Phase 3 studies, Rinvoq met all primary and ranked secondary endpoints. The primary endpoints include:

• In SELECT-EARLY, 52 percent of MTX-naïve patients treated with Rinvoq 15 mg achieved ACR50 vs 28 percent treated with MTX at week 121
• In SELECT-MONOTHERAPY, 68 percent of MTX-IR patients treated with Rinvoq 15 mg achieved ACR20 vs 41 percent treated with continued MTX at week 141
• In SELECT-COMPARE, 71 percent of MTX-IR patients treated with Rinvoq 15 mg plus MTX achieved ACR20 vs 36 percent treated with placebo plus MTX at week 121
• In SELECT-NEXT, 64 percent of csDMARD-IR patients treated with Rinvoq 15 mg plus csDMARDs achieved ACR20 vs 36 percent treated with placebo plus csDMARDs at week 121
• In SELECT-BEYOND, 65 percent of biologic-IR patients treated with Rinvoq 15 mg plus csDMARDs achieved ACR20 vs 28 percent treated with placebo plus csDMARDs at week 121

"The discovery and development of Rinvoq is indicative of AbbVie's long-standing commitment to advancing the science for people living with immune-mediated conditions," said Michael Severino, M.D., vice chairman and president, AbbVie. "Today's FDA approval marks an important milestone in our pursuit to deliver innovative medicines that advance care for people living with rheumatoid arthritis."

Clinical Remission

Patients taking Rinvoq achieved clinical remission, a state characterized by almost no disease activity and symptoms, even without methotrexate.2-3,6 Approximately 30 percent of patients treated with Rinvoq achieved clinical remission (as assessed by DAS28-CRP<2.6) at week 12 in SELECT-COMPARE and week 14 in SELECT-MONOTHERAPY compared to six percent with placebo plus methotrexate and eight percent with methotrexate, respectively.1 In SELECT-EARLY, 36 percent of patients treated with Rinvoq achieved clinical remission (as assessed by DAS28-CRP<2.6) at week 12 compared to 14 percent with methotrexate.1 

Durable remission rates were observed up to week 26. Forty-eight percent of patients treated with Rinvoq alone in SELECT-EARLY and 41 percent of patients treated with Rinvoq plus methotrexate in SELECT-COMPARE achieved clinical remission at weeks 24 and 26, compared to nine percent with placebo plus methotrexate and 18 percent with methotrexate, respectively.1 Analysis at weeks 24 and 26 were not controlled for multiple comparisons.3,10

Radiographic Inhibition

Rinvoq significantly inhibited radiographic progression as measured by the change in modified total Sharp score (mTSS) from baseline compared to methotrexate in SELECT-EARLY (0.14 vs 0.67) and Rinvoq plus methotrexate compared to placebo plus methotrexate in SELECT-COMPARE (0.15 vs 0.78) through weeks 24 and 26, respectively.1 

Safety

The most common side effects associated with Rinvoq include upper respiratory tract infections (common cold, sinus infections), nausea, cough and pyrexia.1 Patients treated with Rinvoq are at increased risk for developing serious infections that may lead to hospitalization or death. These infections include tuberculosis (TB), invasive fungal, bacterial, viral, and other infections due to opportunistic pathogens. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.1 Lymphoma and other malignancies have been observed in Rinvoq-treated patients.1 Thrombosis, including deep vein thrombosis, pulmonary embolism, and arterial thrombosis, have occurred in patients treated with JAK inhibitors used to treat inflammatory conditions.1 Patients treated with RINVOQ also may be at risk for other serious adverse reactions, including gastrointestinal perforations, neutropenia, lymphopenia, anemia, lipid elevations, liver enzyme elevations, and embryo-fetal toxicity.1 

Ease of Use and Access

Designed to help accommodate the physical limitations of people living with RA, the packaging for Rinvoq includes a bottle cap with a wide, easy-to-grip texture and an embedded tool that punctures the foil liner to simplify medication access.

FDA Approves Xenleta (lefamulin) to Treat Community-Acquired Bacterial Pneumonia (CABP)

Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections, announced the U.S. Food and Drug Administration (FDA)  approval of Nabriva’s new drug applications for the oral and intravenous (IV) formulations of Xenleta (lefamulin) for the treatment of community-acquired bacterial pneumonia (CABP) in adults. As the first IV and oral antibiotic with a novel mechanism of action approved by the FDA in nearly two decades, Xenleta represents an important new empiric monotherapy treatment option for adults with CABP.

“Today’s approval of Xenleta is a significant breakthrough in the collective fight against the growing threat of antimicrobial resistance and provides a desperately needed IV and oral empiric monotherapy treatment option for adults with CABP,” said Ted Schroeder, chief executive officer of Nabriva Therapeutics. “We are especially proud of this approval because Xenleta was discovered in our labs over a decade ago and the entire development program was designed and executed by our dedicated and passionate team. We are indebted to the patients and researchers who collaborated with us and are excited to bring to patients and healthcare providers a novel, short course, empiric monotherapy treatment option for CABP. Xenleta has a mechanism of action that is different than other approved antibiotics, resulting in a low propensity for the development of resistance, as well as a lack of cross-resistance with the beta-lactam, fluoroquinolone, glycopeptide, macrolide, and tetracycline antibiotic classes. Xenleta has a targeted in vitro spectrum of activity against the most common causative Gram-positive, Gram-negative and atypical pathogens associated with CABP, which aligns with the principles of antimicrobial stewardship.”

“The gravity of antimicrobial resistance cannot be overstated, particularly in the context of treating pneumonia,” said Julio Ramirez, MD, FACP, Professor of Medicine, and Chief within the Division of Infectious Diseases, University of Louisville School of Medicine. “As an infectious disease specialist who treats CABP patients in the hospital setting, I am grateful to have both a new IV and oral option that gives me confidence that my patients will continue to receive appropriate therapy once they are discharged from the hospital.”

Xenleta is available for oral (600 mg every 12 hours) and IV (150 mg every 12 hours) administration with a short 5-to-7 day course of therapy. Clinicians can initiate patients on IV or oral therapy, allowing for potential avoidance of hospitalization, or can transition from IV to oral therapy, which may expedite discharge from the hospital. Currently, the median length of stay for patients with pneumonia is 3-to-4 days, resulting in approximately $17 billion in hospital costs per year in the United States. The opportunity to avoid a hospital admission or to discharge a patient earlier on oral therapy benefits patients and may result in significant savings to the health system.

Both the IV and oral formulations of Xenleta were granted Qualified Infectious Disease Product (QIDP) and Fast Track designation by the FDA. The FDA approval was based on a clinical development program supported by a robust data package, including two pivotal, Phase 3 trials (known as LEAP 1 and LEAP 2) that evaluated the safety and efficacy of IV and oral Xenleta compared to moxifloxacin in the treatment of adults with CABP. LEAP 1 was designed to evaluate 5-to-7 days of IV/oral therapy of Xenleta versus 7-days of IV/oral moxifloxacin, with or without linezolid, with both treatment groups having the option to switch from IV to oral administration after 3-days. LEAP 2 evaluated 5-days of oral Xenleta versus 7-days of oral moxifloxacin. LEAP 1 showed comparable efficacy with moxifloxacin, with or without linezolid, while LEAP 2 showed comparable efficacy with moxifloxacin, with two fewer days of therapy. Xenleta was generally well tolerated in both LEAP 1 and LEAP 2.

“Emergency departments across the country treat hundreds of thousands of patients with CABP each year. Many of these patients, especially elderly patients with comorbidities, are admitted solely because of the lack of an effective and well-tolerated oral treatment option” said Philip Giordano, MD, Vice Chairman of Emergency Medicine at the Orlando Regional Medical Center. “With a new oral antibiotic option that has been shown to be as effective as a respiratory fluoroquinolone, possessing a favorable side effect profile, we can consider sending more patients home directly from the emergency department and avoid costly hospitalizations, which is good for both patient care and the health system.”

Pneumonia is an infection of the lung that can be serious and fatal, especially among older adult patients with comorbidities. There are approximately five million cases of pneumonia in the U.S. each year, and pneumonia is the fifth leading cause of hospitalization and one of the leading causes of infection-related death. Streptococcus pneumoniae is the most common cause of bacterial pneumonia in the U.S. According to recent data from the SENTRY Antimicrobial Surveillance Program, in the U.S., approximately 30 to 60 percent of S. pneumoniae, depending on region, are macrolide resistant. In addition to macrolides, fluoroquinolones are another common treatment option for CABP. This broad-spectrum class is an effective option, however fluoroquinolones carry boxed warnings for several significant safety concerns.

Nabriva expects Xenleta will be available through major U.S. specialty distributors in mid-September 2019. Xenleta will have a wholesale acquisition (WAC) price of $205 per IV patient treatment day and $275 per oral patient treatment day.

“Offering clinicians and patients a new treatment option for CABP that addresses the urgent and growing threat of antimicrobial resistance is our top priority. With that in mind, our team has been working hard to make Xenleta available in the weeks ahead to ensure that patients with CABP who can benefit from this new treatment option can access it,” said Schroeder.

About Xenleta

Xenleta (lefamulin) is a first-in-class semi-synthetic pleuromutilin antibiotic for systemic administration in humans discovered and developed by the Nabriva Therapeutics team. It is designed to inhibit the synthesis of bacterial protein, which is required for bacteria to grow. Xenleta’s binding occurs with high affinity, high specificity and at molecular sites that are different than other antibiotic classes. Based on results from its two global, Phase 3 clinical trials, Nabriva Therapeutics believes Xenleta is well-positioned for use as a first-line monotherapy for the treatment of CABP due to its novel mechanism of action, targeted spectrum of activity, resistance profile, achievement of substantial drug concentration in lung tissue and fluid, availability of oral and IV formulations and a generally well-tolerated safety profile. Nabriva Therapeutics believes XENLETA represents a potentially important new treatment option for the approximately five million adults in the United States diagnosed with pneumonia each year.

In LEAP 1 and LEAP 2 (pooled), the median age of patients treated with Xenleta was 61 (range 19-97) years; 42% of patients were 65 years or older and 18% of patients were 75 years or older. In both trials, approximately half of Xenleta-treated patients had impaired renal function and the most common other comorbidities included hypertension, asthma/COPD and diabetes mellitus. These baseline characteristics were broadly representative of the adult patient population with CABP. 

In LEAP 1, Xenleta demonstrated non-inferiority compared to moxifloxacin, with or without linezolid, for the FDA primary endpoint of early clinical response (ECR) assessed 72 to 120 hours following initiation of therapy in the intent to treat (ITT) patient population (ECR rate = 87.3% for Xenleta and 90.2% for moxifloxacin, with or without linezolid; treatment difference -2.9 [95% confidence interval (CI) -8.5, 2.8]). In LEAP 2, 5-days of oral Xenleta also demonstrated non-inferiority to 7-days of oral moxifloxacin for the ECR endpoint in the ITT population (ECR rate = 90.8% for Xenleta and 90.8% moxifloxacin; treatment difference 0.1 [95% confidence interval (CI) -4.4, 4.5]). Importantly, high-risk patients 65 years and older achieved a similar ECR rate as those less than 65 years of age. The most common adverse reactions in patients receiving Xenleta in LEAP 1 (IV and oral) were administration site reactions, hepatic enzyme elevation, nausea, hypokalemia, insomnia, and headache in LEAP 1, and in LEAP 2 (oral only) diarrhea, nausea, vomiting and hepatic enzyme elevation. Few discontinuations due to adverse reactions were reported (3.3% in both treatment arms) and the 28-day mortality was low and balanced between treatment groups [8 patients (1.2%)] and [7 patients (1.1%)] for Xenleta and comparator, respectively from pooled data for LEAP 1 and LEAP 2.

FDA Approves Rozlytrek (entrectinib) for People With ROS1-Positive, Metastatic Non-Small Cell Lung Cancer and NTRK Gene Fusion-Positive Solid Tumors

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY),  announced  the U.S. Food and Drug Administration (FDA) has approval of  Rozlytrek (entrectinib) for the treatment of adults with ROS1-positive, metastatic non-small cell lung cancer (NSCLC). The FDA has also granted accelerated approval to Rozlytrek for the treatment of adult and pediatric patients 12 years of age and older with solid tumors that have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have progressed following treatment or have no satisfactory alternative therapy.

These approvals are based on results from the integrated analysis of the pivotal Phase II STARTRK-2, Phase I STARTRK-1 and Phase I ALKA-372-001 trials, and data from the Phase I/II STARTRK-NG study. In the integrated analysis, Rozlytrek was studied in several solid tumor types, including breast, cholangiocarcinoma, colorectal, gynecological, neuroendocrine, non-small cell lung, salivary gland, pancreatic, sarcoma and thyroid cancers. In ROS1-positive, metastatic NSCLC, Rozlytrek shrank tumors in 78% of people with the disease (overall response rate [ORR]; N=51) and the duration of response (DoR) ranged from 1.8 to 36.8+ months (N=40 out of 51). Rozlytrek also shrank tumors in more than half of people with NTRK gene fusion-positive, locally advanced or metastatic solid tumors (ORR=57%; N=54), and objective responses were observed across 10 tumor types (DoR ranged from 2.8 to 26.0+ months; N=31 out of 54). Objective responses to Rozlytrek were seen in people with central nervous system (CNS) metastases at baseline.

“Rozlytrek’s FDA approval for two rare types of cancer is an important advance for patients, combining a targeted medicine and genomic testing to bring this new treatment option to patients who are waiting,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “Rozlytrek is the first FDA-approved treatment that selectively targets both ROS1 and NTRK fusions, and, importantly, has also shown responses in these rare cancer types that have spread to the brain.”

“The identification of actionable biomarkers like ROS1 has brought about significant progress in the treatment of lung cancer. This approval brings further hope to people with this rare type of the disease,” said Janet Freeman-Daily, co-founder of The ROS1ders, a group of patients and caregivers affected by ROS1-positive lung cancer. “Up to 40% of people with ROS1-positive non-small cell lung cancer have tumors that have spread to the brain, so now there is a new treatment option for those patients.”

The most common adverse reactions (≥20 percent) with Rozlytrek were fatigue, constipation, altered sense of taste (dysgeusia), swelling (edema), dizziness, diarrhea, nausea, nervous system disorders (dysesthesia), shortness of breath (dyspnea), muscle pain (myalgia), cognitive impairment, increased weight, cough, vomiting, fever (pyrexia), joint pain (arthralgia) and vision disorders.

The FDA’s Accelerated Approval Program allows conditional approval of a medicine that fills an unmet medical need for a serious or life-threatening disease or condition. The accelerated approval of Rozlytrek for NTRK gene fusion-positive solid tumors is based on tumor response rate and durability of response, and continued approval may be contingent upon verification and description of clinical benefit in the confirmatory trials.

Biomarker testing for ROS1 in NSCLC and NTRK gene fusions across all solid tumors is the only way to identify people who are eligible for treatment with Rozlytrek. Genentech is leveraging its expertise in developing personalized medicines and advanced diagnostics, in conjunction with Foundation Medicine, to help identify people with ROS1 and NTRK gene fusions. Foundation Medicine will submit Foundation®One CDx to the FDA for approval as a companion diagnostic for Rozlytrek. An FDA-approved companion diagnostic for Rozlytrek is not available at this time.

Rozlytrek is now available in the United States for adults and children 12 years of age and older. For those who qualify, Genentech offers patient assistance programs for people prescribed Rozlytrek by their doctor through Genentech Access Solutions.

About the Integrated Analysis

This approval is based on an integrated analysis including data from 51 people with ROS1-positive NSCLC and 54 people with locally advanced or metastatic NTRK gene fusion-positive solid tumors (10 tumor types, >19 histopathologies) from the Phase II STARTRK-2, Phase I STARTRK-1 and Phase I ALKA-372-001 trials. This approval is also based on data from the Phase I/II STARTRK-NG study in pediatric patients. The studies enrolled people across 15 countries and more than 150 clinical trial sites. Safety was assessed from an integrated analysis of 355 people across these four trials.
