Jun 2026Series BVida Ventures (lead); Illumina Ventures; CureDuchenne Ventures; Vertex Ventures HC; SymBiosis; Otsuka Pharmaceuticals; UCB Ventures; Vivo Capital; Leaps by Bayer; ARK Investment Management; Medical Excellence Capital; ARCH Venture Partners$125MVida Ventures led an oversubscribed USD 125 million Series B financing in SonoThera, with participation from ARK Invest and other strategic and financial backers. The round was announced and closed in June 2026, and the proceeds are intended to advance SonoThera’s lead programs for Duchenne muscular dystrophy and autosomal dominant polycystic kidney disease into the clinic, while expanding its broader pipeline of ultrasound-mediated nonviral genetic medicines. The financing is structured as venture equity rather than an acquisition or debt transaction, and the sources do not disclose a valuation, revenue, or EBITDA figure. Strategically, the raise supports development of SonoThera’s RIPPLE ultrasound delivery and PORE payload engineering platforms, which the company positions as a nonviral alternative to traditional gene therapy. The company says the capital will fund clinical progress for its lead programs and broaden its pipeline across multiple organ systems. ARK Invest participated alongside Vida Ventures, Leaps by Bayer, Otsuka Pharmaceutical, UCB Ventures, CureDuchenne Ventures, Vivo Capital, SymBiosis, and several existing investors, indicating a broadly syndicated late-stage venture round. SonoThera is a South San Francisco-based biotechnology company focused on next-generation genetic medicines aimed at the root causes of disease. Its disclosed near-term development priorities are DMD and ADPKD, with the first DMD trial targeted for 2027. The company describes its platform as ultrasound-mediated, targeted, and redosable, and the round is meant to help move these programs from preclinical development into the clinic.
