A $10 million pot of seed money has catapulted Ctrl Therapeutics Inc. into existence, enabling it to advance an immunotherapy approach in which tumor cells are extracted from the bloodstream rather than the tumor itself. By targeting circulating tumor-reactive lymphocytes (cTRLs) in the blood, the company’s cell therapy platform – which originated at the University of Toronto – is designed to address the challenges of existing cell therapy technologies.

Artificial intelligence (AI)-powered drug discovery startup Protai Bio Ltd. raised $12 million in additional seed funding, bringing the total amount to $20 million that will see the company build out an oncology drug discovery pipeline derived from its AI proteomics platform.

Seamless Therapeutics GmbH raised $12.5 million in seed financing to take forward a novel gene editing technology based on reprogramming recombinase enzymes.

Aldena Therapeutics Inc. secured $30 million in seed funding from founding investor Medicxi to bring siRNA-based drugs to the skin.

Newco Relation Therapeutics Ltd. is showing its colors after raising $25 million in a seed round to work on integrating single cell transcriptomics, functional genomics and machine learning – and cut through previously undecipherable combinatorial space – to find and validate drug targets in the non-coding genome.

Resalis Therapeutics Srl closed a €10 million (US$10.6 million) seed round to progress toward the clinic a micro-RNA (miR) inhibitor in development for metabolic disease indications. Riccardo Panella, chief scientific officer and founder, identified the potential of a particular miR species, miR-22, as a target for metabolic syndrome while conducting studies on its potential role in oncology while at Harvard Medical School and Beth Israel Deaconess Medical Center.

Vevo Therapeutics Inc. raised $12 million in an over-subscribed seed round to build out an in vivo single-cell screening platform, which will enable it to interrogate simultaneously the effects of small molecule drug leads on multiple cancer cell lines.

Newco Vacv Biotherapeutics Ltd. has raised $3 million in a seed round to complete preclinical development of next-generation oncolytic viruses that are engineered to overcome previous shortcomings of this modality.

Astrivax BV has raised €30 million (US$30.1 million) in a seed round to take forward the development of a novel vaccine technology that combines a plasmid vector with a replication-competent virus.

Increased payload capacity for gene therapies, off-the-shelf genome-engineered allogeneic cell therapies, reduced cost of goods and faster bioprocesses, are promised by “big DNA” specialist Replay Holdings LLC. The newco arrived with a $55 million seed round and having assembled a portfolio of technologies for writing and delivering large pieces of DNA.
