Insulin cartridge holders recalled, HCV drug approved

This column reviews details on recent recalls, warnings, and approvals.


Recalls and warnings

A recall of one lot of paliperidone extended-release tablets (3 mg, 90-count bottles) due to failed test results for dissolution. Subtherapeutic levels could occur if patients with schizophrenia and schizoaffective disorders take two or more consecutive dosing regimens with affected tablets. The probability of this is low, and no related adverse events have been reported, according to the manufacturer's investigation.

A recall of one lot of apixaban (Eliquis) 5-mg tablets to the retail/dispensing level due to a customer complaint that a bottle contained 2.5-mg tablets. Recalled products were distributed in February 2017.

Approvals

Voxilaprevir in combination with sofosbuvir and velpatasvir (Vosevi) to treat adults with chronic hepatitis C virus (HCV) genotypes 1 through 6 who have mild or no cirrhosis. The fixed-dose tablet is the first treatment approved for patients previously treated with sofosbuvir or other HCV drugs that inhibit nonstructural protein 5A (NS5A). Safety and efficacy were tested in two clinical trials of about 750 adults with mild or no cirrhosis. Overall, 96% to 97% of patients who took the new combination drug had no virus detected in their blood 12 weeks after completing treatment. Due to concerns about hepatitis B virus (HBV) reactivation in co-infected patients, clinicians should screen for current or prior HBV infection before starting treatment with the new drug. The most common adverse reactions were headache, fatigue, diarrhea, and nausea. The drug is contraindicated in patients taking rifampin.

L-glutamine oral powder (Endari) to reduce severe complications associated with sickle cell disease. The orphan drug's safety and efficacy were evaluated in a randomized, placebo-controlled trial of patients ages 5 to 58 years with sickle cell disease and two or more painful crises within the previous 12 months. Over 48 weeks of follow-up, treated patients had fewer sickle cell crises on average than those who received placebo (median, three vs. four), as well as fewer hospitalizations for sickle cell pain (median, two vs. three) and fewer days in the hospital (median, 6.5 days vs. 11 days). Patients who received the drug also had fewer occurrences of acute chest syndrome compared with those who received placebo (8.6% vs. 23.1%). Common side effects include constipation, nausea, headache, abdominal pain, cough, pain in the extremities, back pain, and chest pain.

Haegarda to prevent hereditary angioedema attacks in adolescent and adult patients. The orphan drug, a C1 esterase inhibitor derived from human plasma, is administered subcutaneously by the patient or caregiver after proper training. It is indicated for routine prophylaxis, not to treat acute attacks. Efficacy was demonstrated in a multicenter controlled trial of 90 patients ages 12 to 72 years with symptomatic disease. Participants were randomized to receive two weekly subcutaneous doses of 40 IU/kg or 60 IU/kg. During 16 weeks of treatment, both doses were associated with a significantly reduced number of attacks versus placebo periods in the same patients. The most common side effects were injection-site reactions, hypersensitivity reactions, nasopharyngitis, and dizziness. The drug should not be used in patients who have had life-threatening hypersensitivity reactions to a C1 esterase inhibitor preparation or its inactive ingredients.
