Asher Biotherapeutics Inc. raised $55 million in a series A financing round to take forward a series of engineered cytokines designed to selectively activate T cells or other immune effector cells, in order to eliminate both the toxicities and the loss of efficacy that can result from indiscriminate activation.
Merck & Co. Inc. is paying $1.85 billion, or $60 per share, to acquire Pandion Therapeutics Inc. on the back of early stage data in human volunteers for its lead program, PT-101, an engineered interleukin-2 mutein fused to an Fc backbone, which is designed to stimulate targeted expansion of regulatory T cells for use in autoimmune disease indications.
Cancer immunotherapy developer Xilio Therapeutics Inc. has raised $95 million in series C financing to support its efforts to move a duo of tumor-selective candidates into the clinic. IND applications for both its interleukin-2 agonist, XTX-202, and anti-cytotoxic T-lymphocyte-associated protein 4 antibody, XTX-101, are planned for this year.
The already intriguing IL-2 pathway as a therapeutic target gained still more traction after San Francisco-based Nektar Therapeutics Inc. unveiled melanoma data with bempegaldesleukin (bempeg), its CD122-preferential agent in the class.
Synthekine Inc., a California startup developing new medicines for cancer and autoimmune disorders, has closed an $82 million series A financing. The funds will help the company move its two lead programs into the clinic, expand its discovery pipeline and hone its cytokine engineering platforms.
DUBLIN – Versant Ventures is committing $35 million in series A funding to Bright Peak Therapeutics Inc., which is developing a pipeline of engineered cytokines that are produced using a novel chemical synthesis technique rather than the recombinant methods that have underpinned more than four decades of biotechnology development.
Seattle-based Neoleukin Therapeutics Inc. is targeting the end of 2020 for an IND submission related to prospective cancer immunotherapy NL-201, described as an engineered, hyperstable agonist of interleukin-2 (IL-2) and IL-15. It’s meant to eliminate alpha receptor binding and thereby overcome the problems with native IL-2.
