Event Summary

On August 21, 2026, Alvogen announced a strategic licensing and commercialization agreement with Rhythm Pharmaceuticals covering two biosimilar candidates: AVT34 (proposed biosimilar to Imfinzi/durvalumab) and AVT87 (proposed biosimilar to Hemlibra/emicizumab). Under the semi-exclusive U.S. agreement, Alvogen retains rights to commercialize directly alongside Lotus, while Lotus will commercialize through its U.S. subsidiary Alvogen. Alvogen remains responsible for development and regulatory approvals in the U.S. and will be the exclusive supplier. In Asia, Lotus gains exclusive commercialization rights in eight markets: South Korea, Taiwan, Thailand, Vietnam, the Philippines, Singapore, China — Hong Kong, and Malaysia. The deal could bring Alvogen up to $150 million in upfront and milestone payments plus ongoing supply revenues. The agreement expands Alvogen's commercial reach and Lotus's biosimilar portfolio in oncology and rare diseases.
