The Week Ahead In Biotech May 23-29: Eton, Lantheus FDA Decisions, Adcom Test For Provention, Chiasma Data Presentation

Biotech stocks advanced in the week ended May 21, as risk aversion forced traders to buy into defensives. As earnings news flow tapered, stocks took cues from clinical readouts. The American Society of Clinical Oncology, which is set to hold its meeting June 4-8, published abstracts submitted by presenters at the conference. These abstracts triggered some stock-specific reactions.

The week witnessed a few top-level executive departures. Cancer biotech Idera Pharmaceuticals, Inc. (IDRA) lost its chief medical officer. Gene therapy company Passage Bio, Inc. (PASG) announced the departure of its CMO, while it said its chief financial officer will also leave by this month's end.

Voyager Therapeutics, Inc.'s (VYGR) chief executive officer and CMO called it quits, with the company announcing renewed focus on TRACERT gene therapy technology platform and next-generation targeted AAV capsids.

Moderna, Inc. (MRNA) said its COVID-19 vaccine was approved for emergency use in Japan, while Pfizer, Inc. (PFE)-BioNTech SE (BNTX) received incremental orders from the European Union for the supply of their COVID-19 vaccines. Here are the key catalytic events for the unfolding week.
