Sanofi backs $125M 'clustering' antibody betDiagonal Therapeutics has raised an oversubscribed $125-million series B to advance its lead clustering antibody programme toward the clinic, drawing backing from a syndicate co-led by Sanofi Ventures and Janus Henderson Investors. The company closed a $128-million A round in 2024.Proceeds will primarily support development of DIAG723, a first-in-class clustering antibody designed to correct impaired receptor signaling in hereditary haemorrhagic telangiectasia (HHT) and pulmonary arterial hypertension (PAH). The company plans to initiate a first-in-human study in HHT patients in the first half of 2026, while also advancing additional clustering antibody therapeutics. DIAG723 targets disrupted ALK1 signaling in endothelial cells, a core defect in both diseases that contributes to fragile arteriovenous malformations in HHT and vascular hyperproliferation in PAH. New investors in the round included Deep Track Capital, EcoR1 Capital, Logos Capital, Balyasny Asset Management and Woodline Partners, alongside a group of existing backers such as Atlas Venture, RA Capital Management, Frazier Life Sciences and Lightspeed Venture Partners. As part of the transaction, Sanofi Ventures partner Paulina Hill will join Diagonal's board. EpiBiologics heads to clinic with $107M in the bankEpiBiologics brought in $107 million from a series B financing as it advances its lead asset, a tissue-selective bispecific antibody that degrades all oncogenic forms of EGFR, to the clinic. The funding round was co-led by Google Ventures and Johnson & Johnson Innovation, with new investors Novartis Venture Fund, Aulis Capital, Avego BioScience Capital and Samsara BioCapital joining existing backers Polaris Partners, Digitalis Ventures, Taiho Ventures, Vivo Capital, Codon Capital and Mission BioCapital.Launched in 2023 with $50 million from a series A financing, EpiBiologics' pipeline is headed by EPI-326, which is designed to overcome limitations of existing EGFR therapies by localising degradation to the tumour while sparing normal healthy tissue. A first-in-human study of the therapy for EGFR-driven non–small-cell lung cancer and head and neck squamous cell carcinoma is planned to start early this year."This financing allows us to advance our pipeline of novel bispecific antibodies to selectively degrade disease-driving membrane and soluble targets in oncology and immunology," said CEO Ann Lee-Karlon.Beacon bags $75M to bring gene therapy over the finish line Beacon Therapeutics closed an oversubscribed $75-million series C on Thursday to finish development of laruparetigene zovaparvovec (laru-zova), a gene therapy for X-linked retinitis pigmentosa, and ready for commercialisation.Life Sciences at Goldman Sachs Alternatives led the round, with participation from the Retinal Degeneration Fund, the venture arm of Foundation Fighting Blindness. Existing backers, including investors Syncona Limited, Forbion, Oxford Science Enterprises and Advent Life Sciences also participated.The fresh funding, which will also go towards development of earlier-stage programmes, including those for geographic atrophy and an inherited cone rod dystrophy, adds to Beacon's $170-million series B and $121-million series A, raised in 2024 and 2023, respectively.Pfizer pitches in seed funding for protein degradation newco Enodia Enodia Therapeutics clinched €20.7 million ($25 million) in seed funding on Thursday to support its aspirations of designing small-molecule targeted degraders of previously "undruggable" secreted and membrane proteins.The round was co-led by Elaia, Pfizer Ventures and Bpifrance, with participation from Wallonie Entreprendre, Argobio Studio, MACSF, The Institut Pasteur, InvestSud, Sambrinvest and Mission BioCapital.The biotech's discovery platform, which combines machine-learning technology with proteomics-based secretome analysis and structural validation, builds on discoveries made at the Institut Pasteur. It leverages a large chemical space spanning several families of well-characterised inhibitors and a tailored library of signal-peptide cell lines.Enodia aims to selectively modulate the SEC61 translocon, where secreted and transmembrane proteins are directed into the secretory pathway at the point of synthesis — enabling upstream disease intervention without affecting key physiological functions. Servier puts €200M on the table for biotech investmentsServier launched a venture fund with an initial €200 million ($234 million) in backing that it plans to invest in innovative biotech and technological companies, primarily in Europe. The French drugmaker noted that Servier Ventures will invest through minority stakes in firms operating within its key therapeutic fields of oncology and neurology.Alexis Vandier, who has been appointed global head of Servier Ventures, said the fund "will finance and support emerging biotech companies and, if needed, provide them access to Servier's scientific expertise and capabilities, to boost their potential and foster the creation of innovative new medicines."The launch of Servier Ventures follows a busy period of business development for Servier last year, including licensing deals with IDEAYA Biosciences and Kaerus Bioscience, as well as the acquisition of Black Diamond Therapeutics. This has continued into 2026, with tie-ups already announced with Insilico Medicine and Iktos.MoonLake surges on FDA green light for skin disease drug pathShares in MoonLake Immunotherapeutics jumped 27% on Thursday after the company said it had aligned with the FDA on a regulatory path forward for its hidradenitis suppurativa drug sonelokimab. The stock jump helped the company recoup a chunk of the ground it lost after a catastrophic sell-off in September, when the company revealed that only one of its two Phase III trials of the IL-17A/F-inhibiting nanobody had met its primary endpoint.Thursday's rebound follows a Type B meeting in which the FDA said MoonLake may be able to seek approval of sonelokimab using existing data from the successful VELA-1 readout, as well as VELA-2, which was the trial that fell short, and the earlier Phase II MIRA study, potentially avoiding the need for another late-stage trial. According to the company, the FDA also specifically advised it should submit the VELA-2 results in its application to inform the drug's safety profile, "regardless of decisions on its utility in establishing [substantial evidence of effectiveness]." Management now plans to file a BLA in the second half of 2026."We acknowledge a path to becoming commercial is a positive," said RBC Capital Markets analyst Brian Abrahams, "but despite this, we continue to think real-world use is likely to be guided by efficacy and see [UCB's approved drug Bimzelx (bimekizumab)] ahead as the IL17-A/F agent of choice, restricting the ultimate [opportunity] for sonelokimab."Anna Bratulic and Elizabeth S.
