Gentibio Inc. has announced preclinical data relating to the company's platform technology, demonstrating technical progress to engineer regulatory T cells (Tregs) for the prevention and treatment of autoimmune diseases.
For privately held Good Therapeutics Inc., founded in 2016 with a platform technology for developing context-dependent therapeutics, the plan had always been to seek a buyer for the first asset to emerge. One came along a little earlier than expected, as Roche Holding AG entered a merger agreement for Good, picking up preclinical-stage PD-1-regulated IL-2 program, in exchange for an up-front cash payment of $250 million.
By using engineered retinal pigment epithelial cells to deliver IL-2 into the tumor microenvironment, investigators at Rice University eradicated ovarian and colorectal tumors in mouse models, and elicited T-cell responses after implantation in primates.
DUBLIN – Anaveon AG raised CHF110 million (US$119.5 million) in a series B round to accelerate development of its interleukin-2 (IL-2) agonist ANV-419, which is currently undergoing a phase I/II trial. “We are putting our compound into multiple clinical trials and multiple indications in parallel,” CEO and co-founder Andreas Katopodis told BioWorld.
Less than six months after closing a $55 million series A round, Asher Biotherapeutics Inc. has added another $108 million in a series B round to accelerate development of its early stage pipeline of targeted cytokine-based immunotherapies for cancer, autoimmune disease and infection.
The hefty $107.5 million series B financing disclosed June 10 by Synthekine Inc. underscored Wall Street’s interest in engineered cytokines, where an army of companies is developing prospects at varying stages – including Bright Peak Therapeutics Inc., which pulled down a series B in almost exactly the same amount as Synthekine, and on the same day.
Bright Peak Therapeutics Inc. closed a $107 million series B round to progress a pipeline of engineered cytokines, which are produced using a chemical synthesis method instead of classical recombinant protein production approaches.
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.
