Cerevel Therapeutics Inc.’s positive results from the long-shot pivotal phase III Tempo-3 trial with tavapadon – the first D1/D5 receptor partial agonist being studied as a once-daily treatment for Parkinson’s disease – added gravy to the $8.7 billion takeover by Abbvie Inc., disclosed late last year. The buyout’s centerpiece was the late-stage asset emraclidine, a positive allosteric modulator of the muscarinic M4 receptor, touted as a potential best-in-class, next-generation antipsychotic for schizophrenia, which strikes more than 5 million people in the G7 (U.S., France, Germany, Italy, Spain, U.K. and Japan).

Eli Lilly and Co. is planning to file for U.S. FDA approval later this year after reporting that tirzepatide met all primary and key secondary endpoints in two phase III trials in obstructive sleep apnea (OSA). Assuming approval, tirzepatide could become the first drug approved specifically for OSA, while providing potential entry access for Medicare Part D coverage, which is denied for the GLP-1 class of drugs approved as obesity medications.

After Sage Therapeutics Inc. reported a phase II failure with oral dalzanemdor, also known as SAGE-718, in mild cognitive impairment related to Parkinson’s disease (PD), Wall Street’s eyes turned to ongoing mid-stage efforts with the same N-methyl-D-aspartate receptor-positive allosteric modulator in Huntington’s disease and Alzheimer’s disease.

Neurotech International Ltd.’s cannabinoid NTI-164 met the primary and secondary endpoints in a phase II/III trial in children with autism spectrum disorder. The company also reported positive top-line data for Rett syndrome in a phase I/II trial.

With no drugs approved by the U.S. FDA for treating Becker muscular dystrophy, Edgewise Therapeutics Inc. reported positive two-year, phase Ib data looking at patients’ ability to physically function, plus biomarker data.

Robust top-line phase III data showed Intra-Cellular Therapies Inc.’s marketed oral atypical antipsychotic drug, Caplyta (lumateperone), achieved statistically significant and clinically meaningful best-in-class results, potentially expanding its reach into the billion-dollar major depressive disorder market. The company’s shares (NASDAQ:ITCI) surged to a 52-week high of $84.89 throughout the day, closing at $79.84, up 23.3%, or $15.08, on April 16.

Investors anxious to see data from Marinus Pharmaceuticals Inc.’s phase III Raise study testing intravenous ganaxolone in refractory status epilepticus (RSE) will have to wait a little longer, as the trial failed to meet the predefined criteria for stopping at the interim analysis, sending shares (NASDAQ:MRNS) down nearly 83%.
