Biotech stocks managed to close the week ending Feb. 4 with gains. Stocks recovered along with the broader markets early in the week, but came under pressure midweek amid negative reaction to some big pharma earnings. The sector came back up in the final session for a firm finish.

(BIIB) shares moved to the downside as they reacted to weak guidance and not-so-promising commentary about sales of the company's Alzheimer's drug Aduhelm.

On the regulatory front, the Food and Drug Administration approved Viatris Inc.'s (VTRS) generic version of AbbVie, Inc.'s (ABBV) dry eye disease drug Restasis. Sanofi (SNY) received the nod for its medication Enjaymo, targeting a rare blood disorder known as cold agglutinin disease.

LogicBio Therapeutics, Inc. (LOGC) shares shed over 50% during the week after the FDA imposed a clinical hold on a Phase 1/2 study of its AAV-delivered genomic editing therapy LB-001 to treat a rate metabolic disorder in children. Here are the key catalysts for the unfolding week.
