The company is also advancing a second ERAP1 inhibitor for autoimmune diseases toward clinical trials in 2025. On May 23, 2024, Greywolf closed an oversubscribed $50 million Series B financing expansion led by Intermediate Capital Group (ICG) Life Sciences, bringing total Series B funds to $99 million (GBP 99 million in one report). Existing investors including Pfizer Ventures, Andera Partners, Canaan Partners, Earlybird Venture Capital, Oxford Science Enterprises, and British Patient Capital participated. Proceeds will broaden the GRWD5769 trial across solid tumor types and expand R&D into autoimmune therapies. Tracy Weightman from ICG joined the board.

Jan 2023Series BEarlybird VC (lead); Pfizer Venture Investments (lead); Canaan Partners; Oxford Science Enterprises; British Patient Capital; Andera Partners$49MGreywolf Therapeutics is a clinical-stage UK-based biotechnology company developing first-of-its-kind antigen modulation therapies to treat immune dysfunction in oncology and autoimmunity. The company's platform focuses on modulating antigen presentation by inhibiting ERAP1 or ERAP2 enzymes to enhance neoantigen generation and presentation, driving tumor-targeted T cell responses and overcoming resistance to existing immunotherapies. Its lead candidate, GRWD5769, is a potent oral ERAP1 inhibitor advancing into clinical trials for solid tumors, both as monotherapy and in combination with PD-1 inhibitors like Libtayo. On January 26, 2023, Greywolf closed an oversubscribed $49 million Series B financing round co-led by Earlybird Venture Capital and Pfizer Ventures (Pfizer Venture Investments), with participation from new investors Oxford Science Enterprises and British Patient Capital ($7 million via Future Fund: Breakthrough), and existing investors Andera Partners and Canaan Partners. The proceeds support the initiation of an adaptive Phase I/II clinical trial of GRWD5769 in solid tumors in the first half of 2023, as well as preclinical development of an ERAP2 inhibitor and the tumor antigen discovery platform. This initial Series B was later expanded in May 2024 with an oversubscribed $50 million extension led by ICG Life Sciences, bringing total Series B funds to $99 million and overall funding to over $128 million across multiple rounds. The expansion funds broaden the Phase 1/2 trial scope, with first clinical data reported at ASCO 2024, and initiate R&D into autoimmune disorders using the antigen modulation platform. Greywolf, founded in 2017 and headquartered in Oxford with operations in Australia, had approximately 45 employees as of recent records and continues to progress its pipeline without disclosed revenue, valuation, or profitability metrics.

The company, founded in 2017 and headquartered in Oxford, UK, targets immuno-oncology with small molecules that alter antigen presentation to make tumors more detectable by the immune system. Around 2018, Grey Wolf completed a £10 million ($14 million) Series A financing led by Andera Partners and Canaan Partners to advance preclinical development of its ERAP1 and ERAP2 programs toward clinical candidates. An additional £2.5 million ($3.3 million) Series A2 round followed from the same investors to accelerate ERAP2 therapies and progress the ERAP1 lead program. These early rounds supported lead optimization, efficacy studies in vitro and in mice, dose-ranging, and early toxicology data ahead of IND-enabling studies.
