J&J's subcutaneous Darzalex nabs another MM approvalUK biotech VC deals post strong 2025 showingEpidarex raises $145M to fuel early UK-US life science betsTox finding scuttles Phase I study of AstraZeneca heart drugTRexBio raises $50M to fund tissue-targeted Treg therapiesJ&J's subcutaneous Darzalex nabs another MM approvalThe FDA on Tuesday approved Johnson & Johnson's Darzalex Faspro (daratumumab and hyaluronidase-fihj) in combination with bortezomib, lenalidomide and dexamethasone (VRd) for adults with newly diagnosed multiple myeloma (MM) who are ineligible for autologous stem cell transplant. The regulatory clearance was based on findings from the Phase III CEPHEUS study, which showed that at a median follow-up of 22 months, patients with MM who received the combination saw an overall negativity rate for minimal residual disease (MRD) of 52.3%, compared with 34.8% for those taking VRd alone. The FDA OK marks Darzalex Faspro's twelfth indication overall, and its fifth in newly diagnosed MM. Last year, the drug was approved in the US and EU for adults with high-risk smouldering MM (see – Spotlight On: J&J's fastest growing drugs).UK biotech VC deals post strong 2025 showing A report from the BioIndustry Association (BIA) suggests that the UK ended 2025 with "clear signs" of renewed momentum and increased investor confidence. The analysis showed that the UK retained its position as Europe's leading national biotech market, representing 30% of all venture financing in the region, despite a 13.2% year‑on‑year drop in venture capital investment, totalling nearly £1.8 billion ($2.5 billion) across 58 deals.The report indicated that despite the start of 2025 being characterised by investor caution, the final quarter delivered a positive shift, with 22 completed deals. In terms of figures, almost 47% of total capital raised last year came from two transactions in the first quarter — Isomorphic Labs and Verdiva Bio — with average deal size rising to £30.8 million, from £18.7 million in 2024."If 2024 was marked by a rebound, 2025 has been a year of caution and strategic maturation," said Jane Wall, managing director of BIA, although she cautioned that "the geopolitical landscape is precarious and the IPO window is entering its fifth year of restricted activity."Epidarex raises $145M to fuel early UK-US life science betsEpidarex Capital has secured more than $145 million in a first close of its fourth fund, as the transatlantic life science venture firm doubles down on company creation and early-stage investing across the UK and US."We believe that the next three years represent a highly attractive window for investing in a new wave of biotech innovation," said managing partner Sinclair Dunlop. Backers include the British Business Bank, Strathclyde Pension Fund, the Scottish National Investment Bank and other international investors.Fund IV will support up to 15 therapeutic and medical device startups built around "breakthrough science" in areas including cardiometabolic, autoimmune and neurological diseases, as well as oncology. The firm said its "strategy is to lead early-stage financings, bridging the equity funding gap to build globally leading companies at scale."Its portfolio includes Apellis Pharmaceuticals, Enterprise Therapeutics, Harpoon Medical, Kynos Therapeutics and Nodthera. Epidarex last raised capital in 2020, closing its third fund at £102.1 million ($141 million).Tox finding scuttles Phase I study of AstraZeneca heart drugAstraZeneca has terminated a Phase I trial of AZD0233, an oral small molecule targeting the CX3CR1 receptor for dilated cardiomyopathy, according to an update posted on ClinicalTrials.gov this week. The first-in-human trial, which enrolled 84 healthy volunteers, was stopped after an "adverse finding in a non-clinical, chronic toxicology study."AZD0233 was positioned as a possible immune-modulating approach to heart failure, aiming to reduce inflammatory cell infiltration in cardiac tissue by selectively targeting CX3CR1, a transmembrane receptor found on certain leukocytes, including monocytes, T cells and NK cellsThe programme entered the clinic in April 2024. Preclinical data published last November in Circulation suggested that modulating CX3CR1 has cardiac protective effects, improving cardiac function in a mouse model of dilated cardiomyopathy.TRexBio raises $50M to fund tissue-targeted Treg therapiesTRex Bio closed a $50-million financing the biotech will use to advance its clinical and preclinical programmes, led by the purpose-engineered TNFR2 agonist TRB-061. The candidate, which is currently in a Phase Ia/b study for atopic dermatitis, is designed to selectively activate regulatory T-cells (Tregs) in inflammatory diseases affecting skin and other barrier tissues. The funding round included new investors Janus Henderson Investors, Balyasny Asset Management and Affinity Asset Advisors, as well as existing backers such as Alexandria Venture Investments, Avego BioScience Capital, Delos Capital, Eli Lilly, Johnson & Johnson Innovation, Pfizer Ventures, Polaris Partners and SV Health Investors. TRexBio's pipeline also includes TRB-071 and TRB-081, designed to address a range of inflammatory and autoimmune conditions, with Phase I studies expected to start in 2027. The company's programmes have emerged from its Deep Biology Platform, which maps human tissue Treg behaviour to disease processes to identify and characterise novel targets.Anna Bratulic and Elizabeth Eaton contributed to this report.
