Marengo Therapeutics Inc. is opening up a new front in the war on cancer by selectively deploying a tumor-infiltrating subpopulation of T cells, which can be activated by a newly identified, antibody-based mechanism. The Cambridge, Mass.-based company is taking forward a scientific concept that has been germinating for several years at founding investor and company creator ATP, which has now launched the firm with an $80 million series A round. Marengo is gearing up for a first clinical trial in 2022. “It’s a new chapter in T-cell biology,” CEO Zhen Su told BioWorld.
There’s a whole group of biotechs trying to create a tougher next-generation CAR T-cell therapy that could have a powerful effect on solid tumors after the technology’s first successes in blood cancer. One of those is London-based Leucid Bio Ltd., which has just raised £11.5 million (nearly US$16 million) in series A financing to develop next-generation CAR T therapies that are able to make it through to solid tumors and attack them.
It's a good news, bad news scenario for exhausted T cells in chronic infections. Multiple groups of investigators reported in the July 26, 2021, online issue of NatureImmunology that even after a chronic hepatitis C virus infection was cured, T cells that had become dysfunctional during the infection retained epigenetic "scars" that prevented them from becoming fully functional memory T cells.

ISA Pharmaceuticals BV has closed a €26 million (US$30.76 million) funding round to advance its cancer immunotherapy product, ISA-101b, in the clinic, as the company aims to tackle the low response rates that hold back this therapeutic approach.
DUBLIN – Mnemo Therapeutics SAS emerged from stealth mode having raised €75 million (US$91 million) in a series A financing round to take forward a new chimeric antigen T-cell (CAR T) platform, which is focused on selectively targeting both solid and liquid tumors expressing a previously undescribed class of antigens and on improving the persistence and fitness of CAR T cells.
Japanese scientists led by Shin Kaneko, an associate professor in the Center for iPS Cell Research and Application at Kyoto University, have developed the first practical bioengineering strategy for generating a universal pluripotent stem cell.
The question of whether Rubius Therapeutics Inc. would disclose data with its cellular therapy, RTX-240, ahead of the American Association for Cancer Research (AACR) meeting next month was answered in a market-satisfying way as the Cambridge, Mass.-based firm rolled out positive findings from the ongoing phase I/II experiment.
Century Therapeutics Inc. raised $160 million in a series C round to progress its preclinical pipeline of allogeneic cell therapies for cancer, which are derived from induced pluripotent stem cells (iPSCs), and to expand its operational, laboratory and production facilities across several locations.
Tscan Therapeutics Inc. CEO David Southwell told BioWorld that his firm’s series C financing of $100 million will allow two IND filings in liquid tumors this year and three – possibly more – in solid tumors starting next year. “We’ll be filing a lot of INDs in solid tumors,” he said. The Waltham, Mass.-based firm works with T-cell receptor-engineered T-cell therapies.
