A second death in the study of davoceticept (ALPN-202) has prompted Alpine Immune Sciences Inc. to stop enrolling participants in two phase I studies of the CD28 co-stimulator and dual checkpoint inhibitor, throwing the program’s future into doubt.

Immunic Inc. plans to forge ahead with oral psoriasis therapy IMU-935 despite stock-punishing results from a phase Ib trial that showed a higher placebo response than expected. Shares of the New York-based firm (NASDAQ:IMUX) closed at $2.08, down $7.12, or 77.4% after findings were made public from a preplanned interim group-level data analysis of the ongoing experiment, which is testing patients with moderate to severe disease. The group averages for Psoriasis Area and Severity Index (PASI) reductions in the two active arms failed to separate from placebo at four weeks, Immunic said. Although the active arms performed as intended, placebo decreases in PASI proved greater than hoped.

Researchers based at the City University of New York (CUNY) have designed a deep learning artificial intelligence (AI) model that can improve preclinical predictions of drug responses in humans. As outlined in the Oct. 17, 2022, online issue of Nature Machine Intelligence, the researchers believe their model – a context-aware deconfounding autoencoder (CODE-AE) – can help improve the quality of early drug response prediction and help reduce subsequent clinical trial failures.

Galecto Inc.’s late-September news from its ongoing phase IIa trial with GB-2064 in myelofibrosis hiked shares of the Boston-based firm and piqued interest in the lysyl oxidase-like 2 (LOXL2) target, where such names as Gilead Sciences Inc. and Pharmaxis Ltd. also have been busy.

The U.S. FDA wants more data on PTC-518 before PTC Therapeutics Inc.'s phase II study of Huntington’s disease can continue enrollment. While stopped in the U.S., the study of the oral, small-molecule splicing modifier still is enrolling participants at sites in several European countries and in Australia.

Milestone Pharmaceuticals Inc. saw a premarket surge in its share price value after a phase III trial of the company’s self-administered, heart rhythm-restoring nasal spray, etripamil, hit its target in a phase III trial, setting up a potential filing with the U.S. FDA in mid-2023.

Human brain organoids transplanted into rats could be used as an in vivo model for the study of neuropsychiatric diseases. Researchers at Stanford University managed to mature human organoid neurons in the somatosensory cortex of the animal's brain and incorporate them into its neural circuitry.The integration improved the morphological and physiological properties of the transplanted neurons. Compared to those of organoids in a Petri dish, human cells preserved their own identity, and they modified the rat's learned behavior through stimulation and reward experiments.

Genetic testing has the potential to identify infants and children with autism potentially years earlier than clinical assessments, improving response to therapies and long-term outcomes. Sema4 Holdings Corp. presented results of a study Oct. 13 at the Child Neurology Society Annual Meeting that showed exome sequencing improved the diagnosis of autism spectrum disorders by up to 21% compared to current methods. At the same time, the research suggested that exome sequencing can identify children at risk of common comorbidities such as epilepsy, enabling more timely interventions.
