Founded amid the booming next-generation antibody-drug conjugate (ADC) space, Sidewinder Therapeutics Inc. has emerged from stealth with an oversubscribed $137 million series B round and plans to advance a lead program into the clinic in 2027.

Newco Sononeu Inc. has launched to translate more than a decade of basic research in controlling cells with ultrasound into novel, non-invasive therapies for conditions including peripheral and diabetic neuropathy. The underlying technology of sonogenetics provides the ability to manipulate cellular activity via ultrasound-sensitive ion channels that respond to acoustic pressure. These channels may be endogenous, or could be delivered by targeted vectors to specific cell types.

Stipple Bio Inc. raised $100 million in a series A financing to support progression of the company’s lead drug, STP-100, an antibody-drug conjugate that binds an undisclosed target, and the company’s Pointillist discovery platform. The round was co-led by RA Capital, a16z Bio+Health and Nextech Invest. Existing investors, including Emerson Collective Investments (managed by Yosemite), GV (Google Ventures), Lola Capital Partners, GordonMD Global Investments and others, also participated in the round.

Excalipoint Therapeutics Inc. launched with an oversubscribed $68.7 million seed financing round to advance a portfolio of T-cell engagers for solid tumors, marking one of the largest early stage financings in China biotech history.

Enodia Therapeutics Inc. was spun out of The Institut Pasteur by Argobio Studio based on the work of Caroline Demangel, co-founder of Enodia and head of the immunobiology and therapy unit at The Institut Pasteur. Demangel’s lab discovered the mechanism of action of mycolactone, a natural Sec61 inhibitor that causes Buruli ulcers.

Newco Kyron Bio is showing its colors after sealing a research agreement with Servier SA, underpinning a claim that it has overcome one of the longest-running challenges of the biotech industry, and developing technology to precisely control the glycosylation of therapeutic proteins.

Newco Vesalic Ltd. has formed to take forward research indicating extracellular vesicles secreted by skeletal muscle cells carry toxic payloads that are key drivers of motor neuron diseases, including amyotrophic lateral sclerosis. The discovery of this process, which is largely external to the brain and the central nervous system, has opened up new targeting possibilities, and Vesalic is now working on in vivo studies to demonstrate preclinical proof of concept.

A project that started as a bioreactor to assist astronauts in deep space to keep medications safe in a microgravity environment could help pharma companies model how drugs behave in the human body. Omnigeniq unveiled at the J.P. Morgan Healthcare conference the first computer model of a human protein as it exists in the body, confirming that native protein topology can be calculated directly from physics.

After closing an oversubscribed $85 million series B round, Quantx Biosciences Inc. is gearing up to begin clinical trials of its two lead immunology compounds, a STAT6 oral small-molecule inhibitor and an IL-17 oral small-molecule inhibitor.

Galux closed a ₩42 billion (US$29 million) series B round Feb. 10, led by Yuanta Investment to bring AI-driven “rational design” to the protein drug development process, already heavily influenced by human engineering.
