Oct 23 (Reuters) – Zymeworks said on Friday Roche has gained rights to develop and commercialize ​its experimental lung cancer drug ‌under a global licensing deal worth up to $813 million.

• Zymeworks will receive $55 million upfront and an additional $40 million when the ‌Swiss ​drugmaker begins a ⁠planned dose-optimization study of ⁠the drug ZW209

• Roche will take over the development of the treatment after Zymeworks completes the dose-escalation ​portion of an ongoing early-stage study

• The company said the ⁠drug targets DLL3, a ⁠protein commonly found on ​small-cell lung cancer cells but rarely seen ​in healthy tissue

• Roche has agreed ‌to partner on ZW209 before efficacy data were available because of “the innovation and differentiation in our trispecific ⁠T-cell engager platform,” Zymeworks CEO Kenneth Galbraith told Reuters

• The first patient is expected ⁠to ‌be enrolled before the ⁠end of 2026, Galbraith said

• ​The ‌company said it could ​receive up ⁠to $718 million in development, regulatory and commercial milestone payments, in addition to tiered royalties on future sales
