Tag: Amgen , Teneobio , acquisition
Amgen entered an agreement to acquire Teneobio, a privately held, clinical stage biotechnology company developing a new class of biologics called Human Heavy-Chain Antibodies, for a $900 million upfront, and future contingent milestones, potentially worth up to an additional $1.6 billion.
The acquisition includes Teneobio's bispecific and multispecific antibody technologies, which will enable significant acceleration and efficiency in the discovery and development of new molecules that have the potential to treat a wide range of diseases across Amgen's core therapeutic areas. These platforms complement Amgen's antibody capabilities with the addition of a heavy-chain only platform that allows a streamlined, sequence-based discovery approach for target binders, as well as Teneobio's T-cell engager platform, providing a differentiated approach to Amgen's current BiTE platform.
The acquisition will also add TNB-585, a Phase 1 bispecific T cell-engager for the treatment of metastatic castrate-resistant prostate cancer (mCRPC), and several preclinical oncology pipeline assets with the potential for near-term IND filings.
"The acquisition of Teneobio will strengthen our ability to develop innovative medicines to treat patients with serious illnesses and to bring to market best-in-class products, particularly with respect to multispecific and bispecific medicines directed against targets in a wide range of diseases across our core therapeutic areas," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "Teneobio's antibody platform complements our existing capabilities and could potentially give us a more diverse set of building blocks that can be developed into new multispecific therapeutics. In addition, the availability of Teneobio's CD3 engager technology will allow us to broaden our capabilities in generating bispecifics, and with our own technology, enable customization of the T cell engaging domain of the molecules depending on the disease and target."
In June 2021, AbbVie acquired TeneoOne, Inc. (a Teneobio affiliate), which includes TNB-383B, an anti-CD3/BCMA bispecific for the treatment of relapsed or refractory multiple myeloma. Prior to close of the Amgen acquisition, three Teneobio affiliates will be spun-off to Teneobio's existing equity holders: TeneoTwo, Inc. (anti-CD19/CD3), TeneoFour, Inc. (anti-CD38 enzyme inhibitor) and TeneoTen, Inc. (anti-HBV/CD3).
The acquisition, subject to customary closing conditions, is expected to close 2H21.
