Acelyrin Inc. said a vendor used by Fortrea Inc., a CRO the company used for its phase IIb/III study testing interleukin-17A inhibitor izokibep in psoriatic arthritis, incorrectly programmed the study’s protocol and created a dose sequencing error, resulting in some patients in two of the four dosing arms to randomly receive placebo and active treatment instead of the intended alternating pattern. The discovery has prompted a review of other studies involving the CRO, including a study that failed to reach statistical significance in September.

Development of the candidate, which was also under phase IIa investigation in psoriatic arthritis, will be stopped.

Astria Therapeutics Inc.’s potential $320 million deal with Ichnos Sciences Inc. to bring aboard an OX40 portfolio for atopic dermatitis puts the firm in line to compete with big pharma, which is trying – at a much later stage – the same mechanism of action.
Scientists at Egenesis Inc. have transplanted kidneys from genome-edited pigs into cynomolgus monkeys that remained functional for long periods after transplantation. The monkeys, whose own kidneys were removed during the surgery, survived for a median of 176 days after receiving one pig kidney. Maximal survival was just over 2 years. The data were published today in Nature. Egenesis CEO Mike Curtis told reporters that the study has achieved the longest survival to date “using clinically translatable immunosuppression … longer survival has been achieved using really aggressive immunosuppression that really isn’t clinically translatable.”
