The artificial intelligence-first approach to drug discovery may be boosting productivity but has also exposed the fact that in silico design can only go so far. At some point it will be necessary to revert to the conventional method and synthesize a protein and do an experiment. Now newco Adaptyv Bio aims to smooth this transition by applying cell-free systems and micro fluidics to enable proteins to be synthesized and validated at nano scale.

With the backing of €2 million (US$2.17 million) in seed funding from venture capital company Adbio partners, French biotech Calida Therapeutics hopes that drawing on some U.S. academic research into thrombo-inflammatory disorders will enable it to develop a series of monoclonal antibodies.

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.

Acute thrombosis, including heart attack and stroke, is a leading cause of mortality worldwide. Yet only a small fraction of patients can be treated with current therapeutic or surgical interventions. Enter Basking Biosciences Inc., a 2019 startup aimed at developing a short-acting, fast-onset thrombolytic drug alongside a reversal agent for treating acute ischemic stroke.

Two years after its formation, Mosaic Therapeutics Ltd. has raised $28 million in a series A to begin commercialization of research carried out by the Translational Cancer Genomics Lab at the Sanger Institute in Cambridge, U.K., into the genetic vulnerabilities of multiple tumor types and how that impacts response to therapy.

Smart Immune SAS has received €17.5 million (US$19 million) in grant and equity funding from an EU innovation program to advance development of its “thymus in a dish” T-cell therapy.

The role of G protein-coupled receptor 35 (GPR35) in gastrointestinal (GI) diseases has been genetically validated for some time, with several pharmaceutical companies advancing programs designed to tackle the target; however, most of these efforts to date have focused on increasing GPR35 activity. ThirtyFiveBio’s approach is different: The newly founded virtual biotech company believes that antagonizing the target and thereby blocking unwanted GPR35 signaling may be a more appropriate way to address GI conditions, including digestive tract cancers.

More than a decade ago, three scientists were part of a team at G1 Therapeutics Inc. that led to the now-approved CDK4/6 inhibitor Cosela (trilaciclib). The same work also led to findings showing CDK2 as a promising target for cancers that developed resistance to CDK4/6 inhibition.

In Alzheimer’s, the amyloid beta hypothesis has proved most persistent in terms of drug development efforts to date, but aggregation of other pathogenic factors – phosphorylated tau (p-tau), APOE4, TREM2 and alpha-synuclein, for example – have also emerged as hallmarks of the disease. It’s that aggregation that seven-year-old Truebinding Inc. aims to target with its lead program, TB-006, a monoclonal antibody against galectin-3.

An investor has seen promise in First Wave Biopharma Inc.’s targeted, systemic gastrointestinal disease biotherapeutics, offering $4 million in a private placement as enrollment picks up pace in a phase II trial for the company’s lead candidate, adrulipase.
