After raising $17 million in seed funding, immunotherapy-focused biotech company, LTZ Therapeutics Inc., is announcing plans for the fledgling company whose acronym stands for “Lift to Zenith.” CEO and co-founder Robert Li told BioWorld that the company’s three-tiered immunotherapy platform will focus on reducing immunosuppression, reprogramming innate immunity and modulating adaptive immunity.
Nanobiotix SA has just presented new data from an open-label preclinical study evaluating the action of its nanoparticle-enhanced radiotherapy, NBTXR3, with the triple blockade of PD-1, LAG-3, and TIGIT on mice carrying cancerous cells. PD-1, LAG-3 and TIGIT are three checkpoint inhibitors which regulate the natural killer cells usually targeted in combination therapy in immuno-oncology.
Epitopea Ltd. raised $13.6 million in seed financing to take forward a new cancer immunotherapy platform based on the identification of a new class of tumor-specific antigens encoded by non-canonical genomic sequences.
Bristol Myers Squibb Co.’s relatlimab will hit the market as the first U.S. FDA-approved LAG-3 inhibitor, cleared by the agency for use in a fixed-dose combination with Opdivo (nivolumab) to treat adult and pediatric patients with unresectable or metastatic melanoma. The approval, a day ahead of the March 19 FDA target date, adds another type of immune checkpoint inhibitor to the oncology arsenal, which already includes drugs targeting PD-1/PD-L1 and CTLA4.
Adagene Inc. has announced a research collaboration with Sanofi SA, to find “masked” monoclonal and bispecific antibodies that are safer than marketed drugs in oncology, in a deal worth up to $2.5 billion plus royalties. San Diego and Suzhou, China-based Adagene will generate masked versions of Sanofi antibodies, taking responsibility for early stage research activities using its Safebody technology.
Microbiotica Ltd. of Cambridge, U.K., has raised £50 million ($67 million) in series B funding as the company aims to test its microbiome-based technology in early cancer and ulcerative colitis trials. The funding was co-led by new investors Tencent and Flerie Invest, with British Patient Capital on board along with existing investors Cambridge Innovation Capital, IP Group and Seventure. With response rates to checkpoint inhibitors still very low, Microbiotica’s scientists think that the way to improve the immune system’s response to these drugs is by modifying the bacteria present in the gut.
Adagene Inc. has announced a research collaboration with Sanofi SA, to find “masked” monoclonal and bispecific antibodies that are safer than marketed drugs in oncology, in a deal worth up to $2.5 billion plus royalties. San Diego and Suzhou, China-based Adagene will generate masked versions of Sanofi antibodies, taking responsibility for early stage research activities using its Safebody technology. Sanofi will be responsible for later-stage research and all clinical, product development and marketing activities.
Biontech SE and Medigene AG have signed a three-year research collaboration to develop T-cell receptor (TCR) based immunotherapies against cancer. Medigene will receive €26 million ($29.5 million) up front and could receive hundreds of millions of euros per drug in milestone payments from the deal, which will also covers research funding for the period of the collaboration.
Life sciences VC Apple Tree Partners has launched its first U.K.-based portfolio company, providing $53 million in series A funding for immunology specialist Adendra Therapeutics Ltd.
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.
