-Lilly’s retatrutide beats Ozempic on A1C and weight loss in head-to-head diabetes trial
The triple agonist outperformed semaglutide’s highest approved dose over 80 weeks.
In the Phase 3 TRANSCEND-T2D-2 trial, 1,298 adults with type 2 diabetes inadequately controlled with metformin received once-weekly retatrutide 9 mg or 12 mg or Ozempic 2 mg; both retatrutide doses lowered A1C by an average of 2.2% versus 1.8% with Ozempic, from a baseline of 8.3% [1]. Retatrutide patients lost 19.5% to 20.9% of body weight versus 9.4%, while discontinuation for adverse events was 4.8% and 7.9% versus 2.7% [1]. The trial was open-label and the figures are company topline data; retatrutide is not approved anywhere, and full results await a medical meeting and peer review [1], [2].
-Artiva halts AlloNK cell therapy after two patient deaths and cuts 94% of staff
The San Diego biotech has stopped dosing and is weighing a merger, sale or liquidation.
Artiva Biotherapeutics said one participant in its Phase 2a basket trial in rheumatoid arthritis and other B-cell-driven autoimmune diseases died of a neurological event (leukoencephalopathy) that the investigator and an independent safety review assessed as likely related to fludarabine-associated neurotoxicity, and a second died suddenly about two months after treatment of a cause not yet determined, which the investigator judged unrelated to AlloNK [3]. The FDA asked the company to pause enrollment and dosing in the Phase 2a study, and Artiva said longer-term follow-up did not show the durability of response it needed to continue [3]. The company will cut roughly 94% of its workforce, has engaged Leerink Partners to evaluate strategic alternatives and reported about $319.1 million in cash and investments as of September 30 [3], [4].
-FDA proposes one BLA for individualized gene-editing products as CMS widens gene therapy access model
A draft guidance would let sponsors add patient-specific variants as manufacturing changes.
The FDA’s draft guidance introduces an “Individualized Feature Space,” a set of predefined boundaries within which a genome-editing product may vary from patient to patient while staying within the scope of a single biologics license application; a new variant inside those bounds would count as a manufacturing change rather than a new product [5], [6]. The scope is limited to products for monogenic diseases caused by known pathogenic variants, and comments are due within 30 days of Federal Register publication [5], [6]. Separately, CMS said it will invite makers of therapies beyond sickle cell disease to apply to its Cell and Gene Therapy Access Model, with a request for applications in the coming months [5].
-Single-dose psychedelic nasal spray eased treatment-resistant depression in JAMA trial
Mebufotenin, a short-acting psychedelic, beat a low-dose comparator at 29 days.
In a Phase 2b trial of 193 adults with major depression unresponsive to two to five antidepressants, a single intranasal dose of mebufotenin benzoate 12 mg reduced MADRS scores by 11.1 points at day 29 versus 5.5 points with a 0.3 mg comparator (mean difference −5.3; P = .003) [7]. Day-29 remission was 26% with 8 mg, 18% with 12 mg and 8% with the comparator; 99.7% of adverse events were mild or moderate, and most patients were ready for discharge within two hours [7]. The authors say the drug may need a shorter monitoring period than psilocybin and fewer clinic visits than esketamine [7].
