Lianbio Co. Ltd. has inked a $200 million deal with Tarsus Pharmaceuticals Inc. for greater China rights to the phase IIb/III-stage candidate, TP-03 (lotilaner ophthalmic solution, 0.25%), designed to treat Demodex blepharitis and Meibomian gland disease (MGD). Lianbio will pay $15 million up front and up to $185 million in development and commercialization milestones.
