Mar-24Series CAtlas Venture; Cystic Fibrosis Foundation; Enavate Sciences; OrbiMed; Perceptive Advisors; Q Healthcare Holdings; RA Capital Management; T. Rowe Price; The Rise Fund; Viking Global Investors$182M$435MSionna Therapeutics, a clinical-stage biotechnology company based in Waltham, Massachusetts, develops novel small molecules to treat cystic fibrosis by targeting the CFTR protein, specifically NBD1 stabilizers and complementary modulators like ICL4, aiming for full restoration of CFTR function beyond current standards like Vertex's Trikafta. Founded in 2019 and incubated by RA Capital, Sionna challenges Vertex in the cystic fibrosis market, which affects patients where existing therapies only partially restore CFTR function, leaving room for more effective treatments covering up to 90% of patients. On March 6, 2024, Sionna closed an oversubscribed $182 million Series C financing round led by Enavate Sciences, with participation from new investors Viking Global Investors and Perceptive Advisors, all existing investors including Atlas Venture, OrbiMed, RA Capital Management, The Rise Fund (TPG), Cystic Fibrosis Foundation, T. Rowe Price, and Q Healthcare Holdings (Qatar Investment Authority). The funds support advancing clinical development, positioning the company with four compounds entering trials in 2024: three NBD1 stabilizers (including SION-451 and SION-719 pending GLP toxicology) and SION-109 (Phase 1 started January 2024). Edd Fleming, M.D., from Enavate Sciences joined the board. This round brings total funding to $332 million since inception, providing runway through 2026 for multiple early- and mid-stage trials and potential IPO preparation. It marked the largest Series C in Massachusetts for 2024 at the time.
