Peel Therapeutics believes evolutionary biology holds the key to developing new therapeutics for cancer and inflammation, a relatively unique approach in the world of biotech, but one that is bearing fruit: Its lead molecule is derived from camptothecin, a compound originating from the Chinese Happy Tree that is thought to have evolved as a plant defense mechanism, and it has progressed to a phase I dose escalation study in patients with advanced solid tumors.

With one of the higher series A rounds for 2023, the newly launched Aiolos Bio Inc. pulled in $245 million to advance its lead product, AIO-001, an anti-thymic stromal lymphopoietin monoclonal antibody set to enter a phase II trial for moderate to severe asthma.

Arbele Ltd. founder and CEO John Luk identified and patented cadherin-17 as a therapeutic cancer target, and the company was founded to develop immunotherapies for gastrointestinal cancers, which are prevalent in Asia Pacific.

There are several pan-PIM kinase inhibitors in development for cancer indications, but startup Mysthera Therapeutics AG hopes to become the first biotech company to develop them in the autoimmune diseases space, having secured $3.5 million in seed capital from founding investor Forty51 Ventures.

In the ultra-rare disease congenital hyperinsulinism, an overproduction of insulin leads to persistent hypoglycemia and can cause neurological complications due to high glucose needs of the brain. About half of children go on to develop seizures or intellectual problems, but current therapeutic options are limited and there are no approved drugs specifically for the condition.

Aboleris Pharma has closed a €27.3 million (US$28.7 million) series A financing, funds it plans to put toward progressing into the clinic a monoclonal antibody against a novel T-cell target with “first-in-class potential” to treat rheumatoid arthritis. The Gosselies, Belgium-based company’s antibody, ABO-21009, is designed to “rebalance” the immune system by inhibiting CD45RC, a protein expressed on the surface of a subset of disease-causing T cells.

Arialys Therapeutics Inc. launched this month with $58 million in seed funding, an experimental compound it is developing for autoimmune encephalitis and autoimmune psychosis, and high aspirations for its field. “Yes, I want to treat these patients, I want these patients to have a better life. But I also want drug discovery and development folks to think differently about discovering new drugs for the CNS,” Jay Lichter told BioWorld.

The rapid migration of gene editing technologies from the bench to the clinic has opened up new therapeutic possibilities for patients with previously intractable genetic diseases and difficult-to-treat cancers. But mobilizing gene editing components into a target cell or organ remains a critical step for the field. Integra Therapeutics SL, an early stage Spanish firm, is now engaged in that process with a novel gene writing platform.

Although preclinical studies of genetically engineered interleukin-18 (IL-18) historically indicated its potential in cancer treatment, interest in the cytokine languished after GSK plc shelved its IL-18 therapeutic on lack of responses in a phase II melanoma trial. But in 2020, Yale University-based professor of immunobiology Aaron Ring set about reviving IL-18 as a cancer therapeutic. He went on to engineer a decoy-resistant form of IL-18 and then founded Simcha Therapeutics Inc. to develop the drug – named ST-067.

Galimedix Therapeutics Inc. plans to move its lead compound, GAL-101, into a phase IIa proof-of-concept trial next year, in order to test an intriguing hypothesis associated with certain retinal degeneration conditions. GAL-101 selectively binds misfolded amyloid beta species, and the company believes that this mechanism may benefit patients with the dry form of age-related macular degeneration or with glaucoma.
