The Alphafold machine learning system for predicting a protein’s structure from its amino acid sequence has been adapted to make it possible to design de novo proteins that fold in a particular way and bind to prespecified target proteins. The sister system, called Alphadesign, works by generating random strings of amino acids, using Alphafold to predict their structure, and then iteratively optimizing the design.

Draig Therapeutics Ltd. launched with a $140 million series A and an AMPA receptor modulator program that has completed phase I and will start a phase II trial in major depressive disorder later in 2025. The series A also will enable the company to advance two small-molecule GABA receptor modulators that have the potential to treat a range of neuropsychiatric disorders, into the clinic in 2026.

Aortyx SL secured €13.8 million (US$15.9 million) in a series A funding round for its solution which treats aortic dissection. The company developed a system to repair the aortic tear, which includes a biomimetic, bioresorbable adhesive patch inserted in the aorta using an endovascular catheter and a deployer.

Mosanna Therapeutics secured $80 million in a series A round to develop MOS-118 as a treatment for the nearly 1 billion people globally with obstructive sleep apnea (OSA). The company has completed the formulation work to make the drug into a nasal spray and the initial proof-of-concept animal studies and is now ready to enter clinical trials in patients with OSA.

Proteinqure Inc. has closed an $11 million series A financing round to support the initiation of the company’s first clinical trial for PQ-203, a first-in-class peptide-drug conjugate for triple-negative breast cancer (TNBC). The funds will also be used to advance additional pipeline programs in neurology and nephrology.

A drug that failed in a phase III trial in 2019 is being brought back to the clinic by Repronovo SA, a fertility and women’s health startup that has raised $65 million in a series A. The money will fund a phase II study of nolasiban in improving success rates in assisted reproductive technology, the same indication as the previous phase III failure.

Phase Scientific International Ltd. raised $34 million in a series A round to accelerate research and development of its early disease detection technology for multiple cancers, women's health issues, and infectious diseases.

Chipiron SA will produce a prototype of its ultra-low portable magnetic resonance imaging (MRI) scanner, after raising $17 million in series A financing, as it looks to make MRI more accessible.
