MUMBAI, India — Cipla Limited announced on September 3, 2026, that its wholly-owned US subsidiary, InvaGen Pharmaceuticals Inc., has entered into an exclusive licensing and supply partnership with China-based Qilu Pharmaceutical. Under the agreement, Cipla USA will secure exclusive commercialization rights in the United States for QL2107, a biosimilar candidate to Merck’s blockbuster oncology therapy Keytruda (pembrolizumab). The partnership provides Cipla entry into the high-margin US oncology biologics sector ahead of Keytruda’s loss of exclusivity.
