Samantha Du, Zai Lab

Chi­nese on­col­o­gy spe­cial­ist Zai Lab bro­kers a deal with Macro­Gen­ics for up to 4 bis­pecifics with a mod­est down pay­ment

Saman­tha Du’s Zai Lab has earned its rep­u­ta­tion as a Chi­nese on­col­o­gy part­ner of choice with an ag­gres­sive li­cens­ing strat­e­gy to tap that grow­ing mar­ket. Now, a West Coast bis­pecifics play­er with a lead col­lab­o­ra­tion mol­e­cule al­ready iden­ti­fied will add its name to Zai Lab’s grow­ing rolodex.

Zai Lab will shell out $55 mil­lion up­front — $25 mil­lion in cash and $30 mil­lion in eq­ui­ty — for a mix of Asian and glob­al rights to four of San Fran­cis­co-based Macro­Gen­ics’ bis­pe­cif­ic an­ti­bod­ies, with one lead mol­e­cule al­ready in de­vel­op­ment, the part­ners said Wednes­day.
