Collaboration grants Fosun Pharma exclusive development and commercialisation rights for TEV-56278 in Greater China and Southeast Asia, accelerating clinical data generation and supporting Teva’s global Pivot to Growth strategy in cancer immunotherapy.

  • Teva-engineered TEV-56278 is an anti-PD1-IL2 ATTENUKINE™ therapy in Phase 1 for the treatment of various forms of cancer, including melanoma
  • Fosun Pharma-Teva collaboration agreement established with goal of accelerating clinical data generation for TEV-56278
  • Partnership leverages strategic relationships to enable research and development of innovative treatments to advance Teva's Pivot to Growth strategy

Teva Pharmaceutical Industries Ltd.  and Shanghai Fosun Pharmaceutical  announced that the companies, through their respective subsidiaries, have entered a strategic partnership for the development of investigational TEV-56278, an anti-PD1-IL2 ATTENUKINE therapy.  Teva's internally developed ATTENUKINE technology provides a new mechanism of action, potentially offering high efficacy and low toxicity in a broad array of oncology indications.

Under the terms of the agreement, which aims to accelerate clinical data generation, Fosun Pharma is granted an exclusive license to develop, manufacture and commercialize TEV-56278 in Chinese mainland, Hong Kong Special Administrative Region (SAR), Macau SAR and Taiwan region and select Southeast Asian countries.  Teva retains all development, manufacturing and commercialization rights to the licensed molecule in the rest of the world.  The strategic partnership presents a significant step forward in the global development of TEV-56278, giving Teva the opportunity to leverage Fosun Pharma-generated data in other geographies.

"This partnership with Fosun Pharma in the development of our internally developed TEV-56278, an anti-PD1-IL2 ATTENUKINE therapy with the potential to treat devastating cancers, is the latest advance to ensuring acceleration of our pipeline," said Eric Hughes, MD, PhD, Executive Vice President, Teva Global R&D and Chief Medical Officer.  "TEV-56278 demonstrates the strength of Teva's innovative drug development capabilities and how strategic partnerships with companies such as Fosun Pharma play a pivotal role in advancing therapies on behalf of patients." 

Anti-PD1-IL2 fusion proteins like TEV-56278 represent a novel approach to cancer immunotherapy. TEV-56278 is designed to deliver IL-2 selectively to PD-1+ T cells, thus amplifying anti-tumor T-cell activity while minimizing off-target systemic toxicities.  The targeted approach holds promise for improving outcomes for patients with a variety of oncology diseases.

"We are pleased to partner with Teva on the development of TEV-56278," said Xingli WANG, MD, PhD, Executive President of Fosun Pharma and CEO of the Global R&D Center,  "This collaboration brings together Teva's expertise in innovative drug development with Fosun Pharma's strong oncology development experience and commercial capabilities in the China market, creating a powerful synergy to accelerate the delivery of this important therapy to patients globally."
