The tumor microenvironment is critical for the ability of cancers to survive and grow, and some aspects of the microenvironment are studied, and targeted, accordingly. Tumor immunology is one of the most active areas of cancer research and has become a pillar of treatment. Others, not so much. “The nervous system is the last component of the microenvironment that people have left completely unrecognized,” Humsa Venkatesh told BioWorld. Even in brain tumors and metastases, where the presence of neurons is glaringly obvious, there has been little attention to how the two interact until recently.
Jazz Pharmaceuticals plc and Werewolf Therapeutics Inc. signed a licensing pact that could be worth more than $1.26 billion, assigning Jazz exclusive global development and commercialization rights to Werewolf's preclinical cancer prospect, WTX-613, a conditionally activated interferon (IFN)-alpha molecule known as an Indukine that emerged from Werewolf’s Predator protein engineering platform.
Though conceptually understood for decades, antibody-drug conjugates (ADCs) haven’t begun to come into their own until recently, but oncology drug developers continue to wrestle with challenges, large among them the problem of antigen selection. Lately, companies including names such as Adagene Inc., Bioatla Inc. and Cytomx Therapeutics Inc., have taken particular interest in exploiting features of the cancer growth itself to add more oomph, with focus on special features of the tumor microenvironment (TME).
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 – Abalos Therapeutics GmbH raised €32.5 million (US$37.6 million) in a series A extension, taking the total raise to €43 million, enough to enable the company to generate clinical proof-of-concept data with its lead viral immunotherapy for cancer.
Adlai Nortye Biopharma Co. Ltd.’s $100 million series D financing in July threw new light on the enticing prospect of targeting EP4 in prostaglandin (PGE2)-driven cancers, and a number of players are lined up in the space.
LONDON – Newco Macomics Ltd. has closed its first financing round at £7.4 million (US$10.3 million), enabling it to lay the ground for a new approach to addressing immunosuppression in the tumor microenvironment by modulating disease-specific macrophages.
LONDON – Mestag Therapeutics Ltd. has closed a hefty $45 million seed round to advance development of antibodies targeting activated fibroblasts, in the treatment of cancer and immune diseases.
Gilead Sciences Inc. has acquired a 49.9% equity interest in privately held Pionyr Immunotherapeutics Inc., which could receive up to $1.15 billion in potential future milestone payments in the deal.
