Briggs Morrison, Crossbow Therapeutics CEO

Brig­gs Mor­ri­son helms new MPM on­col­o­gy start­up with Pfiz­er Ven­tures, Po­laris part­ners on board

Brig­gs Mor­ri­son has a new on­col­o­gy biotech in the works.

Syn­dax Phar­ma­ceu­ti­cals said on March 30 that Mor­ri­son was de­part­ing as head of R&D. And now we know why: The long­time in­dus­try ex­ec­u­tive, at one point the chief med­ical of­fi­cer at As­traZeneca, is now CEO and di­rec­tor for MPM Cap­i­tal’s Cross­bow Ther­a­peu­tics, ac­cord­ing to an SEC fil­ing this week.

The Cam­bridge, MA biotech is hunt­ing down an $80 mil­lion round, per the fi­nan­cial doc­u­ment, which out­lines a board com­prised of MPM man­ag­ing di­rec­tor Todd Fo­ley, Pfiz­er Ven­tures part­ner Ire­na Mel­niko­va and Po­laris Part­ners’ Alexan­dra Cant­ley. For­mer MPM se­nior as­so­ciate Geral­dine Paulus is a co-founder and VP of cor­po­rate de­vel­op­ment and op­er­a­tions, per a LinkedIn pro­file.
