The round was co-led by RA Capital Management, Fidelity Management & Research Company and Janus Henderson Investors, with participation from new investors including Frazier Life Sciences, Soleus Capital, and a life science-dedicated investment fund.

The financing will support the continued clinical development of FOG-001 (zolucatetide) – the company's lead investigational Helicon peptide and first and only direct inhibitor of the elusive β-catenin:TCF interaction – including progression toward a registrational trial in desmoid tumors and continued evaluation across a range of genetically simple and more complex tumor types.

Leveraging over a decade of proprietary data, laboratory innovations, and AI- and physics-based algorithms, the company has developed a new class of stabilized, cell-penetrant alpha-helical peptides – Helicons" – capable of modulating intracellular proteins that are inaccessible to traditional drug modalities. Headquartered in Cambridge, Mass., Parabilis is advancing a focused pipeline of multiple first-in-class therapies across both rare and common cancers.
