NEW DRUG APPROVALS
Byvalson for Hypertension
Byvalson (nebivolol/valsartan, Allergan) 5 mg/80 mg tablets have won FDA approval for the treatment of patients with hypertension to lower blood pressure. Byvalson is the first fixed-dose combination (FDC) of a beta blocker and an angiotensin II-receptor blocker available in the United States.
The FDA’s decision was based on positive data from a phase 3, double-blind, placebo-controlled, dose-escalating efficacy and safety study, which enrolled approximately 4,100 patients with stage 1 or 2 hypertension. Treatment with the FDC of nebivolol and valsartan for four weeks demonstrated statistically significant reductions from baseline in diastolic and systolic blood pressure compared with either nebivolol alone or valsartan alone.

Jentadueto XR for Diabetes
The FDA has approved Jentadueto XR (2.5 mg or 5.0 mg linagliptin and 1,000 mg metformin hydro chloride extended-release tablets, Boehringer Ingelheim/Lilly) for the treatment of type-2 diabetes in adults.
Linagliptin works by increasing hormones that stimulate the pancreas to produce more insulin and the liver to produce less glucose. Metformin lowers glucose production by the liver and its absorption in the intestine.
Jentadueto XR is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type-2 diabetes when treatment with both linagliptin and metformin is appropriate.

Ocaliva for Biliary Cholangitis
The FDA has granted accelerated approval to obeticholic acid (Ocaliva, Intercept Pharmaceuticals) for the treatment of primary biliary cholangitis in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA or as monotherapy in adults unable to tolerate UDCA. Obeticholic acid is an agonist of the farnesoid X receptor, a nuclear receptor expressed in the liver and intestine and a key regulator of bile acid and inflammatory, fibrotic, and metabolic pathways.
The approval was based on a reduction in alkaline phosphatase. An improvement in survival or disease-related symptoms has not been established. Continued approval for this indication may be contingent upon the verification of a clinical benefit in confirmatory trials.

Probuphine for Opioid Dependence
The FDA has approved Probuphine (Titan Pharmaceuticals/Braeburn Pharma ceuticals), the first buprenorphine implant for the maintenance treatment of opioid dependence. Probuphine is designed to provide a constant, low-level dose of buprenorphine for six months in patients who are already stable on low-to-moderate doses of other forms of buprenorphine, as part of a complete treatment program. Previously, buprenorphine was approved for the treatment of opioid dependence only as a pill or buccal film.
Probuphine consists of four 1-inch-long rods that are implanted under the skin on the inside of the upper arm. If further treatment is needed, new implants may be inserted in the opposite arm for one additional course of treatment. The FDA is requiring post-marketing studies to establish the safety and feasibility of placing the Probuphine implants for additional courses of treatment.

Afstyla for Hemophilia A
The FDA has granted approval to CSL Behring for the manufacture and marketing of Afstyla (antihemophilic factor [recombinant], single chain), a recombinant factor VIII single-chain therapy for adults and children with hemophilia A. It is the first single-chain product for hemophilia A specifically designed for long-lasting protection from bleeds with dosing two or three times a week.
In clinical trials, patients undergoing prophylaxis with Afstyla experienced a median annualized spontaneous bleeding rate of 0.00. Once activated, Afstyla is identical to natural factor VIII. The treatment is indicated in adults and children with hemophilia A for routine prophylaxis to reduce the frequency of bleeding episodes; for on-demand treatment and control of bleeding episodes; and for the perioperative management of bleeding. It is expected to be available in the summer of 2016.

Flucelvax Quadrivalent Vaccine
Flucelvax Quadrivalent (influenza vaccine, Seqirus), the first four-strain, cell-culture-derived, inactivated seasonal influenza vaccine for people 4 years of age and older, has been approved by the FDA. The vaccine helps protect against the two influenza A viruses and two influenza B viruses that are indicated by the World Health Organization and the FDA as significant for the 2016–2017 flu season.
Flucelvax Quadrivalent is produced using the same cell-culture manufacturing technology as its predecessor, Flucelvax, a trivalent influenza vaccine. Because the two vaccines have overlapping compositions, the clinical efficacy and safety data from clinical trials of Flucelvax are relevant to Flucelvax Quadrivalent.

Tecentriq for Bladder Cancer
The FDA has approved atezolizumab (Tecentriq, Genentech) for the treatment of patients with urothelial carcinoma, the most common type of bladder cancer. It is the first product in its class (programmed death-1/programmed death ligand-1 [PD-1/PD-L1] inhibitors) approved to treat this type of cancer.
Atezolizumab is approved for patients with locally advanced or metastatic urothelial carcinoma whose disease has worsened during or after platinum-containing chemotherapy, or within 12 months after receiving platinum-containing chemotherapy, either before or after surgical treatment.
Atezolizumab targets the PD-1/PD-L1 pathway (proteins found in immune cells and in some cancer cells). By blocking these interactions, the drug may help the body’s immune system fight cancer cells.

FDA REVIEW ACTIVITIES
Breakthrough Therapy Status
Vyxeos for Blood Cancers
An FDA breakthrough therapy designation has been awarded to Vyxeos (cytarabine:daunorubicin, Celator Pharmaceuticals), an investigational product in development as a treatment for acute myeloid leukemia (AML) and other blood cancers. The designation was primarily based on positive results from a pivotal phase 3 trial in older patients with previously untreated high-risk (secondary) AML. The median overall survival for patients treated with Vyxeos was 9.56 months compared with 5.95 months for patients receiving the “7+3” combination regimen of cytarabine and daunorubicin, the standard of care for AML. This represents a 3.61-month improvement in favor of Vyxeos.

Orphan Drug Designations
d-Methadone for Shingles
d-Methadone (dextromethadone, REL-1017, Relmada Therapeutics), an N-methyl-d-aspartate (NMDA) receptor antagonist in development as a treatment for both depression and chronic neuropathic pain, has received an orphan drug designation from the FDA for the management of postherpetic neuralgia (PHN), a painful neuropathic condition resulting from an outbreak of the herpes zoster virus, otherwise known as shingles.
As a single isomer, d-Methadone has been shown to have NMDA antagonist properties with virtually no opioid activity at the expected therapeutic doses. The activation of NMDA receptors has been associated with neuropathic pain, and it is expected that d-Methadone will have a role in pain management by blocking this activity.

RT001 for Friedreich’s Ataxia
FDA orphan drug status has been granted to RT001 (Retrotope, Inc.) for the treatment of patients with Friedreich’s ataxia (FA). The decision followed an announcement that RT001 was well tolerated, with no serious adverse events or dose-limiting toxicities, in the first cohort of a phase 1/2 clinical trial in FA patients.
RT001 is a chemically stabilized form of a natural fatty acid that confers resistance to lipid peroxidation in mitochondrial and cellular membranes.
FA is a debilitating, life-shortening neurodegenerative disorder that affects approximately 5,000 people in the United States, and more than 20,000 people worldwide. A progressive loss of coordination and muscle strength leads to motor incapacitation, the full-time use of a wheelchair, and ultimately early death, typically from cardiomyopathy. There is no approved treatment for FA.

Advisory Committee Action
Abuse-Deterrent Opioid Vantrela ER
The FDA’s Anesthetic and Analgesic Drug Products Advisory Committee and Drug Safety and Risk Management Advisory Committee have voted 14 to three to recommend approval of Vantrela ER (Teva Pharmaceuticals) for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Vantrela ER is an extended-release formulation of hydrocodone bitartrate with Teva’s proprietary abuse-deterrence technology.
The committees also voted that, if approved, Vantrela ER should be labeled as an abuse-deterrent product by the oral, nasal, and intravenous routes of abuse.

DRUG SAFETY ISSUES
Serious Heart Problems With High-Dose Imodium
The FDA has warned that taking higher-than-recommended doses of the common over-the-counter (OTC) and prescription antidiarrheal medication loperamide (Imodium) can cause serious heart problems, including abnormal heart rhythms that can lead to death. The risk of these heart problems may also be increased when high doses of loperamide are taken with several kinds of medications that interact with loperamide.
Most of the reported serious heart problems occurred in individuals who were intentionally misusing and abusing high doses of loperamide in attempts to self-treat opioid withdrawal symptoms or to achieve a feeling of euphoria.
The maximum approved daily dose for adults is 8 mg for OTC use and 16 mg for prescription use. Loperamide is sold under the OTC brand name Imodium A–D (Johnson & Johnson) and as store brands and generics.

Serious Bleeding Risk With OTC Antacids Containing Aspirin
The FDA has issued a warning of the risk of serious bleeding when using over-the-counter (OTC) aspirin-containing antacid products to treat heartburn, sour stomach, acid indigestion, or upset stomach. Many other products for these conditions are available that do not contain aspirin. Aspirin-containing antacids already have warnings about this bleeding risk on their labels; however, the FDA is continuing to receive reports of this serious safety issue.

Canagliflozin and Risk of Leg and Foot Amputations
The FDA says interim safety results from the ongoing Canagliflozin Cardiovascular Assessment Study (CANVAS) found an increase in leg and foot amputations, mostly affecting the toes, in patients treated with the diabetes medication canagliflozin (Invokana, Invokamet, Janssen). The agency has not determined whether canagliflozin increases the risk of leg and foot amputations. It is investigating this issue.
An interim analysis showed that over one year, the risks of amputation for patients in the CANVAS trial were equivalent to seven of every 1,000 patients treated with 100 mg daily of canagliflozin; five of every 1,000 patients treated with 300 mg daily of canagliflozin; and three of every 1,000 patients given placebo.
Canagliflozin is used with diet and exercise to lower blood sugar in adults with type-2 diabetes. It belongs to a class of drugs called sodium-glucose co transporter-2 inhibitors.

CLINICAL TRIALS UPDATE
Efficacy and Safety Results
Sirukumab for RA
A pivotal global phase 3 study investigating subcutaneous sirukumab (GlaxoSmithKline/Janssen Biologics), a human anti-interleukin-6 monoclonal antibody, in adults with moderately to severely active rheumatoid arthritis (RA) has met both coprimary endpoints. The SIRROUND-D trial enrolled RA patients who had an inadequate response to treatment with disease-modifying antirheumatic drugs.
The results showed that inhibition of radiographic progression, or joint destruction, was significantly greater among sirukumab-treated patients, with a mean change from baseline to week 52 in the van der Heijde–Sharp score of 0.50 among patients receiving sirukumab 50 mg every four weeks (n = 557) and 0.46 for patients receiving sirukumab 100 mg every two weeks (n = 557) compared with 3.69 in the placebo group (n = 556). Significant inhibition of radiographic progression was demonstrated in patients naïve to biologic therapy and those treated with biologics in the past, and was seen as early as week 24.

Buprenorphine Buccal Film for Pain
New data have supported the safety and tolerability of Belbuca (buprenorphine) buccal film (Endo Pharmaceuticals) for the long-term management of chronic pain in patients requiring around-the-clock opioids. A phase 3, open-label study enrolled 506 patients with moderate-to-severe chronic pain requiring continuous around-the-clock opioid treatment. Adverse events occurred in 43% and 54% of patients during the titration (n = 506) and long-term treatment (n = 435) phases, respectively. The most common adverse events included nausea (10%), constipation (6%), and headache (4%) during the titration phase, and nausea (8%), vomiting (5%), and upper respiratory tract infection (5%) during long-term treatment. The FDA approved Belbuca in October 2015.

Plinabulin/Docetaxel for NSCLC
Docetaxel is approved for use in patients with non–small-cell lung cancer (NSCLC) after the failure of first-line chemotherapy, but the treatment has an unfavorable toxicity profile that limits its use. An investigational therapy, plinabulin (BeyondSpring Pharmaceuticals), is being developed in combination with docetaxel to provide a regimen with an improved safety profile. Plinabulin is a vascular-disruptive agent with immuno-oncology effects.
In a phase 2 study, plinabulin/docetaxel provided a significant duration-of-response benefit over docetaxel alone (12.7 months versus 1.5 months, respectively; P < 0.05). The combination mitigated some of the toxicities of docetaxel monotherapy. Plinabulin/docetaxel provided significant reductions in grade-3 or grade-4 neutropenia (7% versus 25%) and in asthenia (13% versus 28%); significantly reduced the use of granulocyte-colony stimulating factor (14% versus 29%); and significantly reduced docetaxel dose reductions due to toxicity (6% versus 20%).

Xaracoll for Postoperative Pain
Two placebo-controlled phase 3 pivotal studies evaluating Xaracoll (bupivacaine-collagen bioresorbable implant, Innocoll Holdings) have achieved their primary endpoints, demonstrating post operative pain relief immediately after open abdominal hernia repair. Xaracoll showed consistency across both studies in its treatment effect for both pain reduction and opioid reduction.
The primary efficacy endpoint—the sum of pain intensity over 24 hours for Xaracoll compared with placebo—met statistical significance in both the MATRIX-1 (P = 0.0004) and MATRIX-2 (P < 0.0001) studies. A key secondary endpoint in the MATRIX trials was the sum of pain intensity over 48 hours. Pooled data from the two MATRIX studies were statistically significant for this endpoint (P = 0.0033).

Wearable Artificial Kidney
A prototype of a wearable artificial kidney was recently tested on seven patients at the University of Washington Medical Center in Seattle. The study was led by the device’s inventor, Victor Gura, MD, of Cedars–Sinai Medical Center in Los Angeles. The trial was designed to see how well the wearable kidney might work to safely take over some of the functions of failed kidneys. Patients used the device for up to 24 hours.
The device successfully cleared the blood of urea, creatinine, and phosphorus, and also helped rid the blood of excess water and salt. Patients seemed to tolerate the therapy well, with no effect on circulation and no serious adverse effects, the researchers found. Some redesigns are needed to correct device-related technical problems that occurred during testing.
