The Human Cell Atlas project has delivered a fresh tranche of data mapping fibroblasts in healthy and diseased skin and pointing to drug targets with potential in multiple diseases across a range of tissues. Using single cell sequencing and spatial genomics, a technique for showing how gene expression varies at different locations within a tissue, nine different subpopulations of fibroblasts were identified, six in healthy skin and three in disease samples.
The dash for MASH is gaining momentum, with Roche AG acquiring 89bio Inc. and its phase III FGF21 analogue, pegozafermin, for treating metabolic dysfunction-associated steatohepatitis, in a deal worth up to $3.5 billion. The Swiss pharma is to pay $14.50 per share, valuing San Francisco-based 89Bio at $2.4 billion, a premium of approximately 52% to 89bio’s 60-day average price on Sept. 17, 2025. Shares of 89bio (NASDAQ:ETNB) gained $6.88, or 85%, to close Sept. 18 at $14.96.
Activity in some clinical parameters is leading Atyr Pharma Inc. to plan a sit-down with regulators, even though the tRNA synthetase-derived drug efzofitimod missed its primary endpoint of steroid tapering in the phase III Efzo-Fit study against the interstitial lung disease pulmonary sarcoidosis (PS). CEO Sanjay Shukla said his firm maintains “a high degree of conviction” regarding the candidate. “But I want to make sure we have the best briefing book possible” before consulting with the U.S. FDA, which will happen as soon as possible.
Metabolic dysfunction-associated steatohepatitis (MASH) is a progressive liver disease that has limited available therapies. Shanghai Minwei Biotechnology Co. Ltd. has developed and presented data for MWN-105, a GLP-1/GIP/FGF21 triple agonist aimed at controlling metabolic dysfunction and fibrosis during MASH.
Mayo Foundation for Medical Education and Research (MFMER) and University of Florida have identified atrial natriuretic peptide B (NPR2; guanylate cyclase B) receptor positive allosteric modulators (PAMs) reported to be useful for the treatment of fibrosis.
Anti-aging specialist Juvenescence Ltd. reached the first close of its series B-1 at $76 million and said it is on course to close the round at $150 million in the third quarter of 2025. “The reason for the first close and not waiting for the very end is just so we can start to move the pipeline forward,” said Richard Marshall, CEO. “We’ve got molecules in and waiting to go, so the sooner we can get going on those, the better,” he told BioWorld.
Only a few days out of the European Association for the Study of the Liver annual meeting, the metabolic dysfunction-associated steatohepatitis (MASH) space continues to grab headlines, with GSK plc shelling out $1.2 billion up front to acquire phase III-ready efimosfermin alfa in a deal with Boston Pharmaceuticals Inc. that could end up totaling about $2 billion.
