FDA Approves Mavenclad (cladribine) Tablets for Multiple Sclerosis

In continuation of my update on cladribine

The U.S. Food and Drug Administration,    approved Mavenclad (cladribine) tablets to treat relapsing forms of multiple sclerosis (MS) in adults, to include relapsing-remitting disease and active secondary progressive disease. Mavenclad is not recommended for MS patients with clinically isolated syndrome. Because of its safety profile, the use of Mavenclad is generally recommended for patients who have had an inadequate response to, or are unable to tolerate, an alternate drug indicated for the treatment of MS.

“We are committed to supporting the development of safe and effective treatments for patients with multiple sclerosis,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “The approval of Mavenclad represents an additional option for patients who have tried another treatment without success.”

MS is a chronic, inflammatory, autoimmune disease of the central nervous system that disrupts communications between the brain and other parts of the body. Most people experience their first symptoms of MS between the ages of 20 and 40. MS is among the most common causes of neurological disability in young adults and occurs more frequently in women than in men.

For most people, MS starts with a relapsing-remitting course, in which episodes of worsening function (relapses) are followed by recovery periods (remissions). These remissions may not be complete and may leave patients with some degree of residual disability. Many, but not all, patients with MS experience some degree of persistent disability that gradually worsens over time. In some patients, disability may progress independent of relapses, a process termed secondary progressive multiple sclerosis (SPMS). In the first few years of this process, many patients continue to experience relapses, a phase of the disease described as active SPMS. Active SPMS is one of the relapsing forms of MS, and drugs approved for the treatment of relapsing forms of MS can be used to treat active SPMS.

The efficacy of Mavenclad was shown in a clinical trial in 1,326 patients with relapsing forms of MS who had least one relapse in the previous 12 months. Mavenclad significantly decreased the number of relapses experienced by these patients compared to placebo. Mavenclad also reduced the progression of disability compared to placebo.

Mavenclad must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks. Mavenclad has a Boxed Warning for an increased risk of malignancy and fetal harm. Mavenclad is not to be used in patients with current malignancy. In patients with prior malignancy or with increased risk of malignancy, health care professionals should evaluate the benefits and risks of the use of Mavenclad on an individual patient basis. Health care professionals should follow standard cancer screening guidelines in patients treated with Mavenclad. The drug should not be used in pregnant women and in women and men of reproductive potential who do not plan to use effective contraception during treatment and for six months after the course of therapy because of the potential for fetal harm. Mavenclad should be stopped if the patient becomes pregnant.

Other warnings include the risk of decreased lymphocyte (white blood cell) counts; lymphocyte counts should be monitored before, during and after treatment. Mavenclad may increase the risk of infections; health care professionals should screen patients for infections and treatment with Mavenclad should be delayed if necessary. Mavenclad may cause hematologic toxicity and bone marrow suppression so health care professionals should measure a patient’s complete blood counts before, during and after therapy. The drug has been associated with graft-versus-host-disease following blood transfusions with non-irradiated blood. Mavenclad may cause liver injury and treatment should be interrupted or discontinued, as appropriate, if clinically significant liver injury is suspected.

The most common adverse reactions reported by patients receiving Mavenclad in the clinical trials include upper respiratory tract infections, headache and decreased lymphocyte counts.

FDA Approves Avaclyr (acyclovir ophthalmic ointment) for the Treatment of Herpetic Keratitis

  

 The US Food and Drug Administration (FDA) has approved Fera Pharmaceuticals' New Drug Application (NDA) for Avaclyr (acyclovir ophthalmic ointment) 3% for the treatment of herpetic keratitis. Orphan drug exclusivity was also granted, providing seven years of marketing exclusivity for the product.

“Avaclyr approval is a major milestone for the company,” noted Frank DellaFera, Fera’s founder and President. “Working closely with the eye care community we were able to identify a need for additional options to treat herpetic keratitis. Acyclovir is the gold standard treatment in herpes virus infections so it made sense to provide this therapy in an ophthalmic dosage form1. Fera is thankful to FDA for approving Avaclyr, making it available to physicians and patients in the US.”

Fera launch plans include finalizing its selection of a commercialization partner to provide physicians and patients access to this important therapy.

About Acute Herpetic Keratitis

According to the Center for Disease Control and Prevention (CDC), HSV (Herpes Simplex Virus) keratitis is an infection of the cornea—the clear dome that covers the colored part of the eye—that is caused by HSV. The infection usually heals without damaging the eye, but more severe infections can lead to scarring of the cornea or blindness. HSV keratitis is a major cause of blindness worldwide2-3.

About Avaclyr

Avaclyr (acyclovir ophthalmic ointment) 3%, is a herpes simplex virus nucleoside analog DNA polymerase inhibitor, is indicated in the treatment of acute herpetic keratitis (dendritic ulcers) in patients with herpes simplex (HSV-1 and HSV-2) virus. The most common adverse reactions (2-10%) reported in patients were eye pain (stinging), punctate keratitis and follicular conjunctivitis

FDA Approves Duaklir Pressair

In continuation of my update on formoterol 

Circassia Pharmaceuticals plc (“Circassia” or “the Company”; LSE: CIR), a specialty pharmaceutical company focused on respiratory disease,  announced the US Food and Drug Administration (FDA) has approved Duaklir for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Duaklir is a fixed-dose combination of the long-acting muscarinic antagonist (LAMA) aclidinium bromide (400 mcg) and long-acting beta-agonist (LABA) formoterol fumarate (12 mcg) administered twice-daily via the breath-actuated inhaler Pressair®.  Circassia is on track to launch Duaklir in the United States in the second half of 2019 via its dedicated COPD sales force.

The Duaklir approval is based on a broad clinical database, including data from three phase III studies, ACLIFORM, AUGMENT and AMPLIFY. The label also includes clinical data from the phase IV ASCENT study, which shows aclidinium therapy is effective at reducing COPD exacerbations.  As a result, Duaklir® is the only twice-daily LAMA / LABA in the United States with COPD exacerbation data included in its prescribing information.

Steve Harris, Circassia’s Chief Executive, said: “We are delighted with the FDA approval of Duaklir, which we believe will provide a valuable treatment option for the significant number of patients with COPD in the United States. The addition of Duaklir to our portfolio further strengthens our range of marketed respiratory products and we look forward to launching it in the US in the coming months alongside our aclidinium monotherapy, Tudorza, as part of the significant LAMA / LABA market that is predicted to grow rapidly over the coming years.”

Michael Asmus, Circassia’s Vice President, US Medical Affairs, said: “With guidelines recommending combined LAMA and LABA therapy for a number of COPD patient groups, we believe Duaklir will make an important contribution to the treatment of this debilitating disease. Dukalir’s approval is based on a broad clinical database, including data demonstrating a reduction in the risk of COPD exacerbations driven by its aclidinium component, and we look forward to making this new therapeutic option available to patients across the United States.”

FDA Approves Ibrance (palbociclib) for the Treatment of Men with HR+, HER2- Metastatic Breast Cancer

In continuation of my update on palbociclib

Pfizer  announced that the U.S. Food and Drug Administration (FDA) approved a supplemental New Drug Application (sNDA) to expand the indications for Ibrance (palbociclib) in combination with an aromatase inhibitor or fulvestrant to include men with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer. The approval is based on data from electronic health records and postmarketing reports of the real-world use of Ibrance in male patients sourced from three databases: IQVIA Insurance database, Flatiron Health Breast Cancer database and the Pfizer global safety database.

“With this approval, we are now able to offer Ibrance to the underserved male breast cancer community and provide more patients with HR+, HER2- metastatic breast cancer the opportunity to access an innovative medicine,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology, Pfizer Global Product Development. “We appreciate that our partnership with the FDA has allowed us to take a significant step forward in the use of real-world data to bring medicines to patients who are most in need.”

Ibrance is now approved for adult patients with HR+, HER2- advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine based therapy in postmenopausal women or in men; or with fulvestrant in patients with disease progression following endocrine therapy. With today’s approval, Ibrance is the first and only CDK 4/6 inhibitor indicated in combination with an aromatase inhibitor for the first-line treatment of men with HR+, HER2- metastatic breast cancer in the U.S.

“Men with breast cancer have limited treatment options, making access to medicines such as Ibrance critically important,” said Bret Miller, founder of the Male Breast Cancer Coalition. “We applaud the use of real-world data, a new approach to drug review, to make Ibrance available to certain men with metastatic breast cancer and help address an unmet need for these patients.”

Real-world data is playing an increasingly important role in expanding the use of already approved innovative medicines.1 Due to the rarity of breast cancer in males, fewer clinical trials are conducted that include men resulting in fewer approved treatment options. In the U.S. in 2019, it is estimated that there will be 2,670 new cases of invasive breast cancer and about 500 deaths from metastatic breast cancer in males.2 The 21st Century Cures Act, enacted in 2016, was created to help accelerate medical product development, allowing new innovations and advances to become available to patients who need them faster and more efficiently.3 This law places additional focus on the use of real-world data to support regulatory decision-making.4

Detailed analysis of the use of Ibrance in men with HR+, HER2- advanced or metastatic breast cancer will be presented at an upcoming medical meeting. Based on limited data from postmarketing reports and electronic health records, the safety profile for men treated with Ibrance is consistent with the safety profile in women treated with Ibrance.5

About Ibrance (palbociclib) 125 mg capsules

Ibrance is an oral inhibitor of CDKs 4 and 6,6 which are key regulators of the cell cycle that trigger cellular progression.7,8 In the U.S., Ibrance is indicated for the treatment of adult patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine based therapy in postmenopausal women or in men; or with fulvestrant in patients with disease progression following endocrine therapy.

Ibrance currently is approved in more than 90 countries and has been prescribed to more than 200,000 patients globally.

FDA Approves Mayzent (siponimod) for Secondary Progressive Multiple Sclerosis

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

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

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

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

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

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

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

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

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

FDA Approves Dovato (dolutegravir/lamivudine) for HIV-1 Infection

In continuation of my update on Dolutegravir & Lamivudine

Dolutegravir (DTG)

Lamivudine, commonly called 3TC

ViiV Healthcare  announced the US Food and Drug Administration (FDA) approval of Dovato, a complete, once-daily, single-tablet regimen of dolutegravir (DTG) 50 mg and lamivudine (3TC) 300 mg for the treatment of HIV-1 infection in adults with no antiretroviral (ARV) treatment history and with no known resistance to either DTG or 3TC. Dovato, a two-drug regimen (2DR), reduces exposure to the number of ARVs from the start of treatment, while still maintaining the efficacy and high barrier to resistance of a traditional DTG-based three-drug regimen.

Deborah Waterhouse, CEO, ViiV Healthcare, said: “Building on our innovative portfolio of medicines, Dovato is powered by dolutegravir, an antiretroviral included in multiple combination therapies and the most prescribed integrase inhibitor in the world, 2 coupled with the established profile of lamivudine. With Dovato, the first complete, single-tablet, two-drug regimen for treatment-naïve adults, ViiV Healthcare is delivering what patients are requesting—a chance to treat their HIV-1 infection with as few drugs as possible, marking a significant step in HIV treatment.”

The approval of Dovato is supported by the landmark global GEMINI 1 and 2 studies that included more than 1,400 HIV-1 infected adults. In these studies, DTG + 3TC demonstrated non-inferiority based on plasma HIV-1 RNA <50 copies per milliliter (c/mL), a standard measure of HIV-1 control, at Week 48 when compared to a three-drug regimen of DTG and two nucleoside reverse transcriptase inhibitors (NRTIs), tenofovir disoproxil fumarate/emtricitabine (TDF/FTC), in treatment-naïve, HIV-1 infected adults. The safety results for DTG + 3TC seen in GEMINI 1 and 2 were consistent with the product labelling for DTG and 3TC. No patient who experienced virologic failure in either treatment arm developed treatment-emergent resistance.

Pedro Cahn, principal investigator for the GEMINI study program said: “People are now living longer with HIV and will spend a lifetime taking drugs to suppress their virus. The approval of the fixed dose combination of dolutegravir and lamivudine, a complete, single-tablet, two-drug regimen, marks a pivotal moment in the treatment of HIV-1. Treatment-naïve people living with the virus have a powerful option that delivers non-inferior efficacy to a dolutegravir-based three-drug regimen, allowing them to take fewer ARVs and get and remain suppressed.”

Jeff Berry, Test Positive Aware Network (TPAN), said: “The approval of Dovato is a welcome paradigm shift, as it brings an innovative treatment approach to newly diagnosed adults with HIV-1. By exposing patients to fewer drugs at the start of treatment, the hope is to help address concerns arising from overall management of prolonged ARV therapy.”

DTG/3TC as a complete, once-daily, single-tablet, two-drug regimen for HIV-1 therapy is currently under review by the European Medicines Agency (EMA) and regulatory authorities in Canada, Australia, Switzerland, and South Africa and several additional submissions are planned throughout 2019.

About Dovato (dolutegravir/lamivudine)

Dovato is approved as a complete regimen for the treatment of HIV-1 infection in adults with no known antiretroviral treatment history and with no known substitutions associated with resistance to either dolutegravir or lamivudine. Dovato is a once-daily, single-tablet, two-drug regimen that combines the integrase strand transfer inhibitor (INSTI) dolutegravir (Tivicay, 50 mg) with the nucleoside analogue reverse transcriptase inhibitor (NRTI) lamivudine (Epivir, 300 mg).

Like a DTG-based three-drug regimen, Dovato uses only two drugs to inhibit the viral cycle at two different sites. INSTIs, like dolutegravir, inhibit HIV replication by preventing the viral DNA from integrating into the genetic material of human immune cells (T-cells). This step is essential in the HIV replication cycle and is also responsible for establishing chronic infection. Lamivudine is an NRTI that works by interfering with the conversion of viral RNA into DNA which in turn stops the virus from multiplying.

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

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

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

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

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

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

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

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

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

           

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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