Annexon Biosciences Inc.’s handsome $250 million IPO this summer verified the mounting interest in its two front-running C1q inhibitors: ANX-005, which has turned up promising phase Ib data in Guillain-Barre syndrome (GBS), with a phase II/III effort planned for next year, and ANX-007, due to enter a phase II experiment in geographic atrophy (GA) during 2021 as well.

Sanofi SA is acquiring Principia Biopharma Inc. in a $3.68 billion deal that brings Sanofi three clinical-stage BTK inhibitors and simplifies a partnership that began three years ago.

The matter of how adhesion of its Viaskin Peanut allergy patch relates to efficacy became a major problem for DBV Technologies SA, which drew a complete response letter (CRL) for the once-daily epicutaneous (EPIT) product. Shares of the Montrouge, France-based firm (NASDAQ:DBVT) closed Aug. 4 at $2.34, down $1.76, or 43%, in reaction to the CRL for the patch, designed to protect children ages 4 to 11. The FDA wants DBV to modify the patch, which means a new human-factor study; officials also are requiring clinical data for the modified patch.
