A meta-analysis found no difference in outcomes between autograft nerve repair and repair using Axogen Inc.’s Avance nerve grafts across all types of nerves and gap lengths up to 70 millimeters. Axogen’s allograft nerves allow patients to avoid the potential complications associated with harvesting the individual’s own nerve to use in repair. The study was published in Plastic and Reconstructive Surgery in January.

Low enrollment in a phase III trial and a missed primary endpoint sent Aridis Pharmaceuticals Inc.’s shares tumbling by 35% on Jan. 26, although the company’s AR-301 (tosatoxumab) showed superior efficacy over the control group in Staphylococcus aureus ventilator-associated pneumonia (VAP) patients.

The burgeoning psychedelic therapeutics market experienced a boost Jan. 25 as Small Pharma Inc. announced its synthetic, intravenous formulation of N,N-dimethyltryptamine (DMT), SPL-026, led to a statistically significantly, rapid reduction in depression symptoms in patients with major depressive disorder in a phase IIa trial, thus meeting its primary endpoint. DMT is a powerful hallucinogenic tryptamine substance which works as a 5-HT receptor agonist. It is found naturally in various plants, and is a schedule I controlled substance in the U.S. Although lesser known than other psychedelics such as magic mushrooms and LSD, it produces short-lived but intense auditory and visual hallucinogenic effects.

Microbiome company Finch Therapeutics Group Inc. has suffered one blow after another in the past year with dwindling cash, delayed programs, a terminated deal and three workforce reductions.

Axcella Therapeutics Inc. is working on its comeback to make something else go away. Just before Christmas, Axcella said it was repositioning itself to focus on long COVID-19 and was just granted regulatory guidance on a primary endpoint and study design from the U.K.’s MHRA to conduct a single registration trial of AXA-1125 for those with long COVID fatigue. Axcella will be meeting with the MHRA in the near term to discuss getting an innovative licensing and access pathway application, which is designed to accelerate the approval process. Axcella also has just submitted its IND to the U.S. FDA for a global phase IIb/III study for treating long COVID.

Vasc-Alert LLC’s surveillance technology successfully predicts which dialysis patients are at risk of experiencing stenosis, a study published in the Journal of Vascular Access shows.
