Reviva Pharmaceuticals Holdings Inc. may be headed back to the clinic for another phase III study of brilaroxazine in treating schizophrenia. With a successful series of early and mid-stage studies behind the treatment, the U.S. FDA recommended a second study for the serotonin-dopamine and neuroinflammatory signaling modulator after a pre-NDA meeting in order to net more efficacy results and expand the safety dataset.
Maplight Therapeutics Inc.’s pricing of a $258.9 million financing this week revived the debate over whether targeting the M1 as well as the M4 muscarinic receptor – as Bristol Myers Squibb Co. does with U.S. FDA-approved Cobenfy (xanomeline and trospium chloride) for schizophrenia – is a better strategy than going after M4 alone.
Positive allosteric modulators (PAMs) of the muscarinic acetylcholine M4 receptor show potential against schizophrenia because they can enhance endogenous acetylcholine signaling, which in turn may mitigate psychotic symptoms as well as improve attention and working memory in individuals with the disorder. However, the efficacy of a promising PAM, CVL-231, has been disappointing in clinical trials.
LB Pharmaceuticals Inc. became the first traditional biopharma company to price an IPO in the U.S. since February, raising $285 million through the upsized sale of 19 million shares at $15 apiece. Shares, now listed on Nasdaq under the ticker symbol LBRX, rose 15% to close Sept. 11 at $17.30.
With new and positive phase III data in treating agitation in patients – at home instead of in a clinic – with bipolar disorders or schizophrenia, Bioxcel Therapeutics Inc. is preparing to submit an sNDA in the first quarter of 2026 to expand the label of the company’s Igalmi (BXCL-501). These data also bring the company closer to having the first such treatment that is approved by the U.S. FDA for home use. The unmet need for patients is huge, Vimal Mehta, the CEO of Bioxcel, told the BioWorld Insider podcast. Watch the interview, below.
Dysregulation of cholinergic neurotransmission through muscarinic receptors, particularly the M1 and M4 subtypes, has been implicated in the pathophysiology of schizophrenia. Muscarinic M4 receptor agonists and positive allosteric modulators (PAMs) have demonstrated the ability to modulate the disrupted neural circuits associated with this disorder.
After Recognify Life Sciences Inc.’s phase IIb failure in treating the cognitive impairment in those with schizophrenia, the indication is no closer to a U.S. FDA approved therapy. The placebo-controlled study of inidascamine missed its primary endpoint to improve cognition, joining a list of companies that have tried and failed to find a successful treatment.
Avata Biosciences Holdings Ltd. and Oceanus Bio Inc. have inked a drug discovery and development deal worth up to $95 million for two of Avata’s cannabidiol compounds.
