DUBLIN – In biopharma, U.S. patent grants hardly represent big news. Without them, you simply don’t get to sit at the table. So Onk Therapeutics Ltd.’s receipt of U.S. patent no. 11104735 covering CISH gene knockouts in natural killer (NK) cell therapies for cancer is not a major event in the general scheme of things. At the same time, it is a vitally important enabler for a company that is, paradoxically, both an early mover in the field but also a laggard in the highly competitive race to move NK cells into clinical development.
Hebecell Corp. closed on a $53 million series A funding to continue advancing its off-the-shelf pluripotent stem cell CAR-natural killer cell (PSC-CAR-NK) therapy program into the clinic. Allen Feng, Hebecell’s chief scientific officer, has worked in stem cell development for more than 16 years. He’s seen a lot of technological change, especially in the past two years. Everyone is using the same technology, he said, but added that Hebecell’s technology is different from anyone else’s. It’s much simpler technology and has “very good potential” to move into large-scale industrial production.
Barely a week after cutting a deal with Beigene Ltd. that included an up-front of $45 million cash, Shoreline Biosciences Inc. and Gilead Sciences Inc.-owned Kite are collaborating to develop allogeneic cell therapies in a deal that could bring Shoreline more than $2.3 billion plus royalties.
Heidelberg, Germany-based Affimed NV described its progress at the American Association for Cancer Research meeting and discussed the research in a conference call on 2020 financial results, adding fuel to investor enthusiasm for the firm’s natural killer (NK) cell approach, although the update did not come without some confusion.
Senti Biosciences Inc. stands to receive more than $645 million in up-front, opt-in and milestone payments through a new collaboration and option agreement with Spark Therapeutics Inc.
Only four years after its foundation, Acepodia Inc. raised $47 million in a series B financing round. The funds will help the oncology company move its first cell therapy candidate to phase II trials, while expanding its research and development activities with other products from its tech platform.
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.
DUBLIN – Cellectis SA is picking up $15 million worth of equity in Cytovia Therapeutics Inc. and could earn as much as $760 million in development, regulatory and sales milestones from a deal involving up to five gene-edited allogeneic natural killer (NK) cell or chimeric antigen receptor (CAR-NK) cell therapies employing its Talen (transcription activator-like effector nuclease) gene editing technology.
Nantkwest Inc. and privately held Immunitybio Inc. trotted out positive early interim results from their advanced metastatic pancreatic cancer studies showing median survival rates more than double the historic rates: eight month’s survival compared to only three. “Anything beyond three months has an impact,” Patrick Soon-Shiong, Immunitybio’s CEO and Nantkwest’s executive chairman, told BioWorld, with understatement about one of the toughest to manage indications in medicine.
When the first chimeric antigen receptor T-cell (CAR T) therapy, Kymriah (tisagenlecleucel), was approved in 2016 for treating B-cell acute lymphoblastic leukemia, its developer, Novartis AG, confined the initial rollout to just 20 treating centers. Its label carried a black box warning, because of the risk of life-threatening cytokine release syndrome, and Basel, Switzerland-based Novartis put in place a comprehensive risk evaluation and mitigation system to ensure its safe use. Catamaran Bio Inc., a Boston-based startup that has raised $42 million in seed and series A financing, is considering the administration of similarly engineered natural killer cells in walk-in clinics. “If the product is safe, it can be given as an out-patient treatment,” Chief Scientific Officer Vipin Suri told BioWorld. “As a field, this absolutely has to be our ambition.”
