Teon Therapeutics is a clinical-stage, privately held biopharmaceutical company in Redwood City, California, developing a focused portfolio of orally administered small-molecule drugs that block immunosuppressive, cancer-promoting signaling pathways in the tumor microenvironment. Its GPCR-directed candidates - TT-702, a first-in-class adenosine A2B receptor antagonist, and TT-816, a first-in-class cannabinoid CB2 receptor antagonist - aim to restore anti-tumor immunity for the roughly 88% of solid-tumor patients who do not benefit from existing immunotherapies. The founding team members were primary inventors of Lexiscan, the only FDA-approved selective adenosine therapeutic.
Vivace Therapeutics is a San Mateo, California oncology company turning novel Hippo-YAP pathway biology into first-in-class cancer drugs. Its lead small molecule, VT3989, is a first-in-class YAP/TEAD inhibitor that blocks TEAD auto-palmitoylation and has shown durable responses in treatment-resistant mesothelioma and NF2-mutant tumors. Built on a capital-efficient US-China 'virtual biotech' model, the company has raised roughly $105 million across four rounds and is preparing a registrational Phase 3 trial.
Nurix Therapeutics is a clinical-stage biopharmaceutical company in San Francisco pioneering targeted protein degradation - medicines that destroy disease-causing proteins rather than merely blocking them. Built on its DELigase discovery engine that harnesses the cell's ubiquitin-proteasome system and DNA-encoded library screening, Nurix is advancing a pipeline of degraders and degrader antibody conjugates for cancer and autoimmune disease, led by the BTK degrader bexobrutideg (NX-5948). The company is partnered with Roche, Sanofi, Gilead, and Pfizer (via Seagen) and trades on Nasdaq under NRIX.
858 Therapeutics is a clinical-stage biotechnology company in San Diego building small-molecule cancer drugs aimed at novel targets in DNA damage response, RNA modulation, and innate immunity. Its lead candidate, the oral PARG inhibitor ETX-19477, is in a first-in-human Phase 1/2 trial for advanced solid tumors and has won FDA Fast Track designation for BRCA-mutated, platinum-resistant ovarian cancer. Founded in 2019 by a serial team of San Diego drug developers, the company has raised $110 million across Series A and B financings.
BlossomHill Therapeutics is a San Diego clinical-stage biopharmaceutical company designing small-molecule precision medicines for cancer and autoimmune disease. Founded in 2020 by drug designer J. Jean Cui and biotech veteran Y. Peter Li - the team behind Turning Point Therapeutics (acquired by Bristol Myers Squibb in 2022) - the company is advancing a wholly-owned pipeline led by BH-30643, a first-in-class macrocyclic OMNI-EGFR inhibitor for EGFR-mutant non-small cell lung cancer, and BH-30236, a CLK inhibitor targeting aberrant RNA splicing in AML and high-risk MDS.
Neomorph is a San Diego clinical-stage biotech building molecular glue degraders - small molecules that recruit the cell's own disposal machinery to destroy disease-driving proteins long written off as 'undruggable.' Founded in 2020 out of Deerfield Management with scientific founders who decoded how thalidomide-class drugs work, the company has assembled what it calls the world's largest proprietary molecular glue target space across a broad portfolio of E3 ubiquitin ligases. It has signed multibillion-dollar discovery pacts with AbbVie, Novo Nordisk, and Biogen, dosed its first patient with lead candidate NEO-811 in kidney cancer, and raised roughly $209M across Series A and B.
NeoPhore is a UK small-molecule immuno-oncology company developing first-in-class inhibitors of the DNA mismatch repair (MMR) pathway. By temporarily switching off MMR, its drugs are designed to make tumours generate fresh neoantigens, become visible to the immune system, and respond to checkpoint immunotherapy - extending the benefit of drugs like Keytruda to patients whose cancers are otherwise immune-cold. A 2017 spin-out of Cambridge's PhoreMost, NeoPhore has raised roughly $47M and counts Bristol Myers Squibb and Memorial Sloan Kettering among its backers and collaborators.
Newleos Therapeutics is a Boston-based, clinical-stage biotechnology company building a new generation of treatments for neuropsychiatric disorders. Launched in February 2025 with an oversubscribed $93.5 million Series A, the company in-licensed four clinical-ready oral small molecules from Roche - targeting GABAA-y1, V1a, TAAR1, and GABAA-a5 - aimed at generalized anxiety, social anxiety, substance use disorders, and cognitive impairment. Its name nods to 'eos,' the Greek word for dawn: a new dawn for mental health treatment.
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.
Synnovation Therapeutics is a Wilmington, Delaware precision medicine company building small-molecule cancer drugs aimed at validated oncology targets where greater potency and selectivity could beat the current standard of care. Founded in 2024 by a team of former Incyte medicinal chemistry leaders, it launched with a $102 million Series A led by Third Rock Ventures. Its lead programs are SNV1521, a CNS-penetrant, highly selective PARP1 inhibitor, and SNV4818, a mutant-selective PI3K-alpha inhibitor whose subsidiary Pikavation Therapeutics was acquired by Novartis in March 2026 for $2 billion upfront.
Nocion Therapeutics is a clinical-stage biopharmaceutical company in the Boston area developing a new class of small-molecule 'charged' sodium channel blockers - nocions - that selectively, locally, and durably silence overactive sensory neurons (nociceptors) without numbing everything else. Its lead candidate, taplucainium, is an inhaled powder aimed at refractory and unexplained chronic cough, with broader potential across itch, pain, and neurogenic inflammation. The science was born in the Harvard Medical School and Boston Children's Hospital labs of Bruce Bean and Clifford Woolf.
Frontier Medicines is a precision-medicine biotech using chemoproteomics, covalent chemistry, and machine learning to drug proteins long considered 'undruggable.' Its lead candidate, FMC-376, is a first-in-class dual ON/OFF inhibitor of KRAS G12C now in the Phase 1/2 PROSPER trial. Backed by $315M+ in venture funding and a major AbbVie partnership, the company is one of the most-watched names in next-generation targeted cancer therapy.
