May 2024Series BTCG Crossover (lead); Research Corporation Technologies; Biotechnology Value Fund; Atlas Venture; Lightspeed Venture Partners; Forbion Capital Partners; Brandon Capital; Perceptive Advisors$120MPheon Therapeutics, a London-based biotechnology company specializing in next-generation Antibody-Drug Conjugates (ADCs) for hard-to-treat solid tumors, completed a $120 million Series B financing round on May 21, 2024. The round was led by TCGX (TCG Crossover) with participation from new investors BVF Partners (Biotechnology Value Fund), Lightspeed Venture Partners, and Perceptive Advisors, as well as existing investors Atlas Venture, Brandon Capital, Forbion Capital Partners, and Research Corporation Technologies. Proceeds will advance Pheon's differentiated ADC pipeline through clinical proof-of-concept, including three first-in-class assets targeting a novel antigen highly overexpressed in solid tumors. The lead program features a DAR8 Topoisomerase-1 inhibitor linker-payload with strong preclinical therapeutic index, while the others utilize alternative linker-payloads. Pheon plans to initiate its first Phase 1 clinical trial in 2024, progressing to dose expansion cohorts, and expand in-house technology platforms for optimized ADC constructs. Cyrus Mozayeni, MD, CEO, highlighted the transition to clinical-stage development. Cariad Chester from TCGX joined the board. The funding extends runway through end-2027. This follows a $68 million Series A in 2022 led by Brandon Capital, Forbion, and Atlas Venture. The round reflects surging investor interest in ADCs, with $2.7 billion raised across 57 deals from January 2022 to mid-March 2024 amid acquisitions like ProfoundBio. Over 160 companies, including Pfizer and AbbVie, compete in the field. Pheon positions its novel target and payloads as first/best-in-class for solid tumors, amid clinical successes validating the modality.
Sep 2022Series AAtlas Venture (lead); Brandon Capital (lead); Forbion Capital Partners (lead); Research Corporation Technologies$68MPheon Therapeutics, a London-based biotechnology company specializing in next-generation antibody-drug conjugates (ADCs) for hard-to-treat solid tumors and cancers, emerged from stealth on September 28, 2022, announcing the March 2022 closing of a $68 million Series A financing. The round was co-led by Atlas Venture, Brandon Capital (via its UK operation), and Forbion Capital Partners, with participation from seed investor Research Corporation Technologies (RCT). Funds are designated to advance the company's lead first-in-class ADC program—targeting a novel cancer antigen highly expressed in solid tumors—to clinical proof-of-concept, reach IND within 18 months, and build a pipeline using its proprietary payload platform with novel mechanisms of action, alongside clinically validated or off-the-shelf linker-payload combinations. Leadership includes CEO Bertrand Damour, a serial biotech entrepreneur with prior CEO roles at NBE Therapeutics (sold to Boehringer Ingelheim for $1.4 billion), OncoEthix (acquired by Merck & Co.), and Mind NRG (acquired by Minerva Neurosciences); Chief Scientific Officer Leigh Zawel; VP R&D and co-founder Paul Jackson; and advisor Professor David Thurston, co-founder of Spirogen (whose payload is in approved ADC Zynlonta). The board comprises Michael Gladstone (Atlas Venture), Jonathan Tobin (Brandon Capital, Chair), Rogier Rooswinkel (Forbion), Shaun Kirkpatrick (RCT), and Damour. Pheon's approach balances safety and efficacy by arming novel or validated monoclonal antibodies with its proprietary payloads or standard combinations, positioning it in the surging ADC field amid recent clinical successes from improved payloads and targets. The syndicate highlights investor confidence in Pheon's differentiated platform and rapid clinic progression. Brandon Capital noted this as its largest European investment to date, with Pheon also collaborating with an Australian research institute via Brandon BioCatalyst network.
