FDA Restricts Fluoroquinolone Use
The U.S. Food and Drug Administration (FDA) has twice previously communicated safety information about systemic fluoroquinolones—in August 2013 and July 2008. The safety issues of this medication class described in its latest Drug Safety Communication were also discussed at a November 2015 FDA Advisory Committee meeting.1 The FDA is now advising that the serious side effects associated with the use of fluoroquinolones generally outweigh the treatment’s benefits for patients with sinusitis, bronchitis and uncomplicated urinary tract infections who have other treatment options available to them. For patients with these conditions, fluoroquinolones should be reserved for those who do not have other treatment options.
The FDA safety review showed that use of fluoroquinolones—tablets, capsules and injectable—is associated with disabling and potentially permanent side effects involving the tendons, muscles, joints, nerves and central nervous system. The FDA is now requiring the drug labels and medication guides for all fluoroquinolones to be updated to reflect this new safety information. The FDA is continuing to investigate safety issues with fluoroquinolones and will update the public and the healthcare community with additional information when available.
The safety review of fluoroquinolones included ciprofloxacin (Cipro ER, Cipro), moxifloxacin (Avelox), ofloxacin (Floxin), gemifloxacin (Factive) and levofloxacin (Levaquin).
FDA Will Review Benzhydrocodone & Acetaminophen Combination
Benzhydrocodone hydrochloride (a hydrocodone prodrug) and acetaminophen combination (Apadaz) is an abuse-deterrent, immediate-release fixed-dose combination product for short-term, acute pain management.2 On May 5, the FDA’s Anesthetic and Analgesic Drug Products Advisory Committee and the Drug Safety and Risk Management Advisory Committee voted in favor of approving the agent for its proposed indication. The Prescription Drug User Fee Act date of June 9, 2016, has been set.
OA Drug Enters Phase 2 Clinical Trials
GSK3196165, previously known as MOR103, is a monoclonal antibody that has begun Phase 2 clinical trials to treat patients with inflammatory hand osteoarthritis (OA).3 GSK3196165 is a monoclonal antibody against granulocyte-macrophage colony-stimulating factor (GM-CSF) cytokine.
This European Phase 2 clinical trial, titled “A Study to Investigate the Efficacy and Safety of GSK3196165 in Inflammatory Hand Osteoarthritis (NCT02683785),” is multicenter, double blind and placebo controlled.4 The study will investigate the safety and efficacy of subcutaneous injections of GSK3196165 in adults (n=40) with inflammatory hand osteoarthritis. This study is evaluating the efficacy potential of GSK3196165 on pain, as well as a safety assessment and compound pharmacokinetics.
GSK3196165 is also being investigated in a different Phase 2B study in rheumatoid arthritis (NCT02504671).5 This trial, “Study to Evaluate the Efficacy and Safety of GSK3196165 Plus Methotrexate in Subjects With Active Moderate-Severe Rheumatoid Arthritis,” began in the third quarter of 2015.
Fluoroquinolone use—tablets, capsules & injectable—is associated with disabling & potentially permanent side effects.
Fasinumab Promising for Treating OA Pain
Fasinumab is an investigational nerve growth factor antibody in Phase 2 and 3 clinical trials.6 This placebo-controlled, 16-week study evaluated patients (n=421) with moderate to severe hip or knee OA pain and inadequate pain relief, or intolerance to either acetaminophen and at least one oral non-steroidal anti-inflammatory drug and an opioid.
