The FDA placed a partial clinical hold on Bright Minds Biosciences’ mid-stage trial of BMB-101 in developmental and epileptic encephalopathies, citing toxicity seen in mice and insufficient pharmacokinetic and juvenile toxicity data to support planned pediatric enrollment. The company said the hold affects only the planned U.S. study and does not affect its other ongoing clinical trials; it plans to seek clarification from the FDA and update the study based on the agency’s recommendations.
