Roche’s oral BTK inhibitor fenebrutinib matched Ocrevus in primary progressive multiple sclerosis (PPMS).
In the 985-patient phase 3 FENtrepid trial, fenebrutinib met its primary endpoint of non-inferiority to Ocrevus (ocrelizumab) and cut risk of disability progression by 12% at 24 weeks. Fatal events ran at 1.4% against 0.2% on Ocrevus. Roche will submit its full phase 3 package once the relapsing-MS study FENhance 1 reads out in H1 2026.

Eli Lilly agreed to buy Orna Therapeutics for up to $2.4bn.
The deal takes Lilly into in vivo CAR-T, where a patient’s own cells are reprogrammed into cell therapies without being removed from the body. Orna’s lead candidate is a CD19-directed in vivo CAR-T for B-cell-driven autoimmune diseases, built on circular RNA. It is one of the largest acquisitions of an in vivo cell-therapy company to date.

The FDA issued a complete response letter for REGENXBIO’s RGX-121, its gene therapy for Hunter syndrome.
REGENXBIO disclosed that the agency had turned down its accelerated-approval filing for the ultra-rare paediatric disease, questioning the trial’s eligibility criteria, its natural-history control and the surrogate endpoint used. The FDA set out requirements, including a new controlled study, that are hard to run in such a small population.

DSM-Firmenich agreed to sell its Animal Nutrition & Health business to CVC at an enterprise value of about €2.2bn including an earn-out of up to €0.5bn.
The Swiss group expects to receive €1.2bn in value after closing, of which roughly €0.6bn is net cash, with it retaining a 20% stake in the unit, which had about €3.5bn of net sales in 2025. The sale, due to close by the end of 2026, largely completes its exit from animal nutrition to concentrate on fragrance, taste and health.

The FDA refused to review Moderna’s next-generation flu vaccine.
Moderna said the Center for Biologics Evaluation and Research (CBER) had issued a refusal-to-file letter for mRNA-1010, objecting solely to the trial’s comparator arm, a licensed standard-dose flu vaccine, which it said did not reflect the best-available standard of care. Moderna said the letter raised no safety or efficacy concern.
Moderna rejected the reasoning, noting the FDA had reviewed both phase 3 designs before the trials began and that the filing rested on two positive studies in 43,808 participants that met all primary endpoints. It has requested a Type A meeting.

Isomorphic Labs unveiled a drug design engine it says goes well beyond AlphaFold 3.
The London-based Alphabet company said its proprietary engine roughly doubles AlphaFold 3’s accuracy on the hardest ligand-binding cases, reaching about 50% on cases with little similarity to training data, against about 23% for AlphaFold 3.

The FDA approved Keytruda in platinum-resistant ovarian cancer, a tumour type the drug had never cracked.
Merck said the agency cleared Keytruda plus paclitaxel with or without Avastin for adults with PD-L1-positive platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal cancer in the second or third line. The FDA cleared Agilent’s PD-L1 IHC 22C3 pharmDx as the companion diagnostic alongside it.

BridgeBio’s infigratinib met its phase 3 goal in achondroplasia.
The oral FGFR1-3 selective tyrosine kinase inhibitor improved annualised height velocity by a mean 2.10 cm/year over placebo at week 52 in the PROPEL 3 trial in children (p<0.0001), and met its key secondary on height Z-score. BridgeBio plans US and European filings in H2 2026, setting up a challenge to BioMarin’s Voxzogo.

European life sciences investors managing >€24bn launched a coalition.
Novo Holdings, Sofinnova, Forbion, Omega Funds and HealthCap were among the members founding the European Life Sciences Coalition in Brussels, alongside Invest Europe, to press for more capital to scale the region’s biotech companies.
The coalition put Europe at 7% of global life sciences venture capital against 63% for the United States and 14% for China, and noted that 66 of 67 EU biotech companies to list in the past six years chose to do so outside the EU.

ICON disclosed an accounting investigation and pulled 2025 guidance.
The CRO said a probe into revenue recognition had preliminarily found revenue in 2023 and 2024 may each have been overstated by less than 2%. It delayed its full-year results to 30 April and said it expects to report one or more material weaknesses.

Novartis said Vanrafia slowed kidney-function decline in IgA nephropathy, though its key secondary endpoint missed significance.
In the phase 3 ALIGN study, Vanrafia showed an eGFR difference over placebo of 2.39 mL/min/1.73 m² at week 136, the final analysis’s key secondary endpoint, that fell short of statistical significance (p=0.057). Vanrafia already holds accelerated US and China approval and Novartis plans to file for approval in 2026 regardless of the miss.
