Biotech stocks pulled back yet again during the week ending Jan. 21, with the sector retreating along with the broader market. The news flow tapered off following the frenetic pace of the week that encompassed the JPM Healthcare conference.

On the M&A front, rare disease biopharma Zogenix, Inc. (NASDAQ:ZGNX) agreed to be acquired by Belgium's UCB SA (OTC:UCBJY) for about $1.8 billion.

Here are the key catalytic events biotech investors can look forward to in the unfolding week:
