Antiva Biosciences, Inc.
Antiva Biosciences is a clinical-stage biopharmaceutical company in South San Francisco developing topical, self-administered antiviral therapeutics for diseases caused by human papillomavirus (HPV). Its lead candidate, ABI-2280, is a vaginal tablet designed to clear high-risk HPV infection and treat pre-cancerous cervical lesions (CIN 2,3) without surgery - an approach aimed at preserving reproductive health and supporting the WHO's goal of eliminating cervical cancer.
Quanta Therapeutics
Quanta Therapeutics is a clinical-stage biopharmaceutical company in South San Francisco building allosteric small-molecule inhibitors for RAS-driven cancers. Using a proprietary Second Harmonic Generation (SHG) optical platform that detects subtle changes in protein conformation, Quanta designs oral drugs aimed at KRAS mutations long considered undruggable - including G12D and G12V - that together drive a large share of pancreatic, colorectal, lung and endometrial cancers. Its lead candidate QTX3034 is in Phase 1 trials, with QTX3544 and a pan-KRAS program close behind.
Superfluid Dx, Inc.
Superfluid Dx is a South San Francisco diagnostics company building a blood-based test for Alzheimer's disease and other neurodegenerative conditions. Its platform isolates cell-free messenger RNA (cf-mRNA) from a single tube of blood and pairs next-generation sequencing with RNA deconvolution and machine-learning analysis to read out organ-level biology - aiming to detect disease years earlier than conventional methods and to guide therapy. The company was formed in late 2023 when WRQ Sciences acquired and renamed Molecular Stethoscope, and is led by Fluidigm co-founder Gajus Worthington alongside Stanford bioengineer and serial founder Steve Quake.
