Data establish maximum tolerated dose, supporting progression of lead neuroplastogen compound EB-003 toward IND-enabling studies and First-in-Human clinical trials

Enveric Biosciences, Inc. (NASDAQ: ENVB) (“Enveric” or the “Company”), a biotechnology company focused on developing novel neuroplastogenic small-molecule therapeutics for the treatment of depression, post-traumatic stress disorder (PTSD), and other neuropsychiatric disorders, today announced the successful completion of 7-day Dose Range Finding (DRF) toxicology studies in two preclinical species for its lead drug candidate, EB-003. The results define the Maximum Tolerated Dose (MTD) and represent a key pipeline advancement landmark supporting the Company’s IND-enabling activities and preparation for First-in-Human clinical trials.

The DRF studies were designed to evaluate toxicity and toxicokinetics following daily oral dosing of EB-003, Enveric’s first-in-class neuroplastogen candidate that selectively engages serotonin 5-HT_2A and 5-HT_1B receptors. The findings confirmed oral bioavailability in both species, with dose-dependent increases in plasma EB-003 concentrations observed across the tested range. At higher dose levels, central nervous system (CNS)-related effects were noted in both species, indicative of brain penetration and potential on-target activity. These results provide important safety and tolerability data to guide dosing strategies in future animal studies and First-in-Human studies.

“Completion of the DRF toxicology studies and establishment of the MTD in two preclinical species is a significant and necessary milestone in the development of EB-003,” said Dr. Joseph Tucker, Chief Executive Officer of Enveric. “These findings provide a well-defined reference point for planning human dosing and position us to advance EB-003 into definitive toxicology, safety pharmacology, and genotoxicity studies required for the IND submission to the FDA. This achievement moves us closer to clinical trial readiness for EB-003.”

Determining the MTD offers insight into the relationship between the anticipated therapeutic dose and toxic limits, a critical element in the regulatory pathway toward human testing. In addition, the reproducibility of CNS-related effects, and confirmation of oral bioavailability and brain penetration support the compound’s intended use and inform the design of upcoming studies.

EB-003 is a first-in-class, neuroplastogen designed to selectively engage serotonin 5-HT_2A and 5-HT_1B receptors, targets implicated in neuroplasticity and mood regulation, without inducing hallucinations. Preclinical findings to date support the potential of EB-003 to promote adaptive neural circuit remodeling in animals without inducing motor responses predictive of hallucinogenic effects in humans. These pharmacological characteristics potentially enable outpatient administration for chronic neuropsychiatric indications. EB-003 is advancing through preclinical development toward evaluation in human clinical trials.
