DateStageInvestorsRaisedDeal Summary
Dec 2025Undisclosed stage-$41MAccession Therapeutics is a clinical-stage biopharmaceutical company headquartered in Oxford, UK, developing next-generation cancer immunotherapies using its proprietary TROCEPT platform. Founded in 2021, the company focuses on tumor-targeted immunotherapy designed to activate the immune system in solid tumors resistant to conventional treatment by combining targeted viral delivery with localized immune activation within tumor tissue. The TROCEPT platform targets the integrin αvβ6 and is delivered systemically while designed to bypass healthy tissue and only target tumor cells without the need for screening. On December 4, 2025, Accession Therapeutics announced a Series B funding round of £30.5 million ($40 million USD) from existing investors including iGlobe Partners, Primavera Venture Partners, and Birk Ventures. Since inception in 2021, the company has raised nearly $100 million in total funding. The proceeds from the December 2025 round will be used to generate full clinical data from its ongoing Phase 1 ATTEST study of TROCEPT-01 (ATTR-01), the company's lead program designed to selectively generate a clinically validated checkpoint inhibitor within advanced solid tumors, and to progress TROCEPT-02 (ATTR-02) into the clinic. TROCEPT-02 is designed to deliver a proprietary genetically encoded universal bispecific T cell engager (BiTE) into tumors to facilitate synthetic, MHC-independent synapse formation between cytotoxic T cells and tumor cells.
Apr 2024Undisclosed stage-$31MAccession Therapeutics is a UK-based clinical-stage biotechnology company founded in 2021 and headquartered in Oxford, developing novel first-in-class immunotherapies targeted at solid tumors. The company's proprietary TROCEPT platform uses engineered viral vectors to selectively target tumor cells and deliver potent anti-cancer transgene payloads, designed to overcome limitations of current immunotherapies. On April 25, 2024, Accession Therapeutics raised £25 million to fund the generation of first clinical data for its lead product TROCEPT-01 and advance its second program (TROCEPT-02) to clinical trial readiness. This funding brought total commitments to over £50 million in the 30 months since inception, supported by high-net-worth individuals and venture capital firms including iGlobe Partners, Primavera Venture Partners, and Birk Ventures. The company's founder and CEO is Bent Jakobsen, PhD FMedSci, a serial entrepreneur and immunotherapy pioneer who has previously founded public biotech companies. As a clinical-stage company with no marketed products, Accession Therapeutics has not disclosed revenue or EBITDA figures; the financing proceeds were specifically earmarked for clinical development and manufacturing of trial materials rather than commercial activities.
Nov 2022Series AiGlobe Partners (lead); Primavera Capital Group; Birk Venture$20MAccession Therapeutics is an Oxford, UK-based immunotherapy company developing novel immuno-oncology therapeutics using its Trocept platform, which employs genetically modified adenoviruses to target cancer cells specifically via integrin binding, delivering potent anticancer payloads with minimal toxicity. The company's two lead preclinical programs at the time were aimed at reaching IND stage by end-2023 and entering clinic in early 2024, focusing on high specificity, potency, and countering tumor diversity. Founded by CEO Bent Jakobsen, a pioneer in T cell receptor therapy for cancer, the firm follows a prior seed round of £11m. On November 21, 2022, Accession Therapeutics raised £16.6m (approximately $20m USD equivalent based on query context) from new investor iGlobe Partners (with Dr Yoke Sin Chong joining as board observer), alongside Primavera Venture Partners, Birk Venture, and biotech angels. iGlobe Partners led the round as per query details. Funds were allocated to advance the two lead preclinical programs to clinical trials and progress the earlier-stage pipeline. Later developments include a December 2025 Series B raise of $40m (£30.5m), bringing total funding since 2021 to nearly $100m from high-net-worth individuals and VCs including iGlobe Partners, Primavera Venture Partners, and Birk Ventures, supporting Phase 1 data for TROCEPT-01 (ATTR-01) and advancement of TROCEPT-02.
