Seaport Therapeutics Inc. joined Nasdaq May 1, raising gross proceeds of $254.9 million, as its parent, Boston-based Puretech Health plc moved to exit the market, opting for a sole listing on the London Stock Exchange (LSE) in order to reduce its cost base and cut bureaucracy.

Dermatology specialist Leo Pharma A/S is moving into gene therapy with the $50 million acquisition of Replay Holdings LLC, a seed-stage company that is developing high capacity herpes simplex virus vectors to treat rare inherited diseases.

Microbiome specialist Enterobiotix Ltd. has raised £19 million (US$25.7 million) to fund phase IIb development of its lead program EBX-102-02 in the treatment of irritable bowel syndrome with constipation (IBS-C).

New U.K. clinical trials regulations coming into force today, April 28, aim to reduce the time taken to get approval for studies and introduce a category of lower risk trials which will be automatically assessed in 14 days. The key measure to cut timelines is the Combined Review, under which sponsors will be able to submit a single application for regulatory review by the Medicines and Healthcare products Regulatory Agency and ethics review by the Health Research Authority, the body responsible for managing ethics committees.

The funding momentum that was building at the end of 2025 was maintained in the first quarter (Q1) of 2026, with a rebound in venture capital (VC) investment in U.K. biotech. Overall investment in the sector during Q1 was £552 million (US$748 million), of which £516 million was in VC.

Artificial intelligence tools are springing up at multiple points along drug discovery and development, but despite the hype, as yet there is minimal return on investment (ROI). “I would say a lot of companies sort of get this big excitement about AI, but then when you look at how much ROI they get, it’s actually very little. And that’s because the workflow and the process, end-to-end, isn’t mapped to really understand where AI can truly make an impact,” said Laura Matz, chief science and technology officer at Merck KGaA.

Netris Pharma SA has delivered positive phase Ib data showing its first-in-class netrin-1 inhibitor NP-137 alleviates resistance to chemotherapy in pancreatic cancer. This could represent an important advance in treating these tumors, which are notoriously resistant to chemotherapy.

Researchers in the U.K. have developed an AI-driven method of identifying viruses in wild animals with the potential to spillover into humans. The technique makes it possible to use the genome sequences of the spike proteins by which viruses enter host cells to assess the potential to infect humans without having to isolate an individual virus and tests its infectivity in the lab.
