Pfizer Inc. is paying $1.25 billion up front and up to $4.8 billion in milestone payments to gain global, ex-China rights to SSGJ-707, a PD-1/VEGF bispecific antibody from 3Sbio Inc. that recently won China clearance for a phase III study in lung cancer as a potential first-line monotherapy. Announced after U.S. market hours May 19, the exclusive agreement for SSGJ-707 spells up to $6.15 billion combined for Shenyang, China-based 3Sbio, along with separate tiered double-digit royalty payments on sales of SSGJ-707, if approved.
