 | Nov 15, 2016 08:12PM ET

Earnings reports, pipeline updates and regulatory news were overshadowed by the run-up to the Presidential election and the surprise win of Donald Trump. In fact, the biotech sector responded favorably to Trump’s victory on hopes that there will be fewer drug pricing headwinds considering Trump was not as vocal as Hillary Clinton about rising drug prices and excessive price hikes. Trump’s pro-business stand is also expected to benefit the sector.

Recap of the Week’s Most Important Stories

Gilead HBV Drug Gains FDA Approval: Gilead (NASDAQ:GILD) , which is facing a slowdown in hepatitis C virus (HCV) franchise sales, gained FDA approval for Vemlidy (tenofovir alafenamide, TAF), a once-daily treatment for adults with chronic hepatitis B virus (HBV) infection with compensated liver disease. Approval comes with a boxed warning regarding the risks of lactic acidosis/severe hepatomegaly with steatosis and post-treatment severe acute exacerbation of HBV. With HBV being an under-treated disease that affects up to 2.2 million in the U.S., Vemlidy provides patients with a new treatment option.

Dynavax Plunges on Heplisav-B CRL: Dynavax’s shares plunged almost 65% on a complete response letter (CRL) from the FDA for Heplisav-B. The company was looking to get Heplisav-B approved for the immunization of adults against hepatitis B infection.

While the agency said that it is yet to complete the review of information submitted by Dynavax in early October, the CRL has asked for information on several topics including clarification regarding specific adverse events of special interest (AESIs), a numerical imbalance in a small number of cardiac events in a single study (HBV-23), new analyses of the integrated safety data base across different time periods, and post-marketing commitments. This is the second time that Dynavax has received a CRL for Heplisav-B. Dynavax said that given the time and resources that will be needed to gain approval, it may not be able to advance the program on its own and is looking for a pharmaceutical or financial partner.

FDA Lifts Partial Clinical Hold on Adaptimmune Treatment: The FDA has removed the partial clinical hold on Adaptimmune’s planned study of its NY-ESO SPEAR T-cell therapy in myxoid/round cell liposarcoma (MRCLS). The company will now commence a pilot study under a revised protocol with patient screening scheduled to start in the fourth quarter. The partial clinical hold was announced in August and had nothing to do with safety. The agency had asked the company to provide additional CMC information and clarification of certain study design-related queries before the commencement of the study.
