FDA approves first injection-free treatment for severe hypoglycemia
On July 24, 2019, the U.S. Food and Drug Administration (FDA) approved Baqsimi™ (glucagon) nasal powder as the first injection-free therapy for the emergency treatment of severe low blood sugar (hypoglycemia) in diabetic patients ages four and older. Hypoglycemia occurs when blood sugar levels drop significantly, resulting in a variety of symptoms with confusion being the most common. It is typically seen in diabetic patients who are using insulin therapy but may also occur if they are taking certain oral medications. In clinical trials involving a total of 201 patients, Baqsimi™, when compared to glucagon injection, was shown to adequately raise blood sugar levels. The approval of Baqsimi™ provides patients an effective new treatment option that can be easily administered into the nose.
FDA adds labeling restrictions to high dose Xeljanz®/Xeljanz XR® used for ulcerative colitis
On July 26, 2019, the FDA announced the approval of a new boxed warning for an increased risk of blood clots and death for patients taking a 10mg twice daily dose of Xeljanz®/Xeljanz XR® (tofacitinib), which is the approved dose for short term use in patients with ulcerative colitis. In addition, the FDA has restricted the approved use of Xeljanz®/Xeljanz XR® for ulcerative colitis to specific patients who are not adequately treated or cannot tolerate certain other medicines. The new labeling restrictions are the result of an FDA review of interim data from an ongoing safety trial that examined both low dose and high dose regimens of the medicine in patients with rheumatoid arthritis (RA). The announcement is an update to the FDA Drug Safety Communication issued in February 2019 alerting the public of an increased risk for blood clots in the lungs in patients with RA.

New chlamydia vaccine candidates successfully generate immune response
On Aug. 12, 2019, results from the first-in-human phase 1 trial of vaccine candidates for chlamydia were published in The Lancet. Chlamydia is the most commonly reported sexually transmitted disease in the U.S., with more than 1.7 million reported cases in 2017. The trial included 35 healthy female participants ranging from 19-45 years old and randomly assigned them to one of three treatment groups, including two variations of the vaccine and placebo. Results of the trial showed that 100% of patients in the treatment groups demonstrated an immune response to the vaccine without serious adverse reactions. Although the trial did not demonstrate chlamydia transmission prevention, the preliminary safety and efficacy of the vaccine candidates confirms promise for further clinical development.
