- Sonnet BioTherapeutics Holdings, Inc. (SONN) is a clinical-stage, oncology-focused biotechnology company that develops targeted biologic drugs using its proprietary FHAB (Fully Human Albumin-Binding) platform, which employs a fully human single-chain antibody fragment to bind human serum albumin for enhanced delivery to tumor and lymphatic tissues; the platform supports modular constructs for cytokines, peptides, antibodies, and vaccines. Founded in 2011 and headquartered in Princeton, New Jersey, the company operates primarily in the United States with a pipeline targeting oncology, autoimmune, inflammatory, and hematological conditions through cytokine-derived therapeutics for solid tumors, platinum-resistant ovarian cancer, pancreatic ductal adenocarcinoma, chemotherapy-induced peripheral neuropathy, and diabetic peripheral neuropathy. Core products and programs include SON-1010 (IL-12-FHAB) in Phase 1/2a for solid tumors including ovarian cancer via a collaboration with Roche combining it with atezolizumab (Tecentriq); SON-1210 (IL-12-FHAB-IL-15) advancing in an investigator-initiated Phase 1/2a study for pancreatic cancer through a Master Clinical Collaboration Agreement with the Sarcoma Oncology Center and the Innovative Immuno-Oncology Consortium; SON-080 (low-dose rhIL-6) licensed to Alkem Laboratories in October 2024 for Phase 2 development in diabetic peripheral neuropathy in India following positive Phase 1b/2a results; and SON-5010, an anti-HER2 antibody-drug conjugate platform made available for drug discovery partnerships in February 2025. Recent major developments encompass stockholder approval in December 2025 of a business combination with Hyperliquid Strategies Inc. via reverse merger, including an $888 million cryptocurrency treasury reserve strategy with HYPE token integration, a $5.5 million private placement of convertible preferred stock and warrants in July 2025, appointment of new board members including former Boston Fed President Eric Rosengren, and plans to operate biotech assets including SON-1010 as a subsidiary of the combined entity while issuing contingent value rights to Sonnet shareholders.
