Rhea-AI Summary
Pasithea Therapeutics has presented updated interim data from its Phase 1 study of PAS-004, a next-generation macrocyclic MEK inhibitor, at ASCO 2025. The study enrolled 21 patients with MAPK pathway-driven advanced solid tumors across six dosing cohorts. Key findings show PAS-004 demonstrating preliminary clinical activity in heavily pre-treated patients, with notable results in cohort 4A (15mg capsule). A stage 4 BRAF-mutated melanoma patient achieved stable disease with -14.9% tumor reduction after 5+ months. The drug showed favorable pharmacokinetics with a half-life exceeding 60 hours and maintained good tolerability with only grade 1 or 2 adverse events. Of 16 evaluable patients, 10 achieved stable disease, with progression-free survival up to 159 days and overall survival up to 253 days. The results suggest PAS-004's potential as a best-in-class MEK inhibitor for various MAPK pathway-driven tumors.

Rhea-AI Summary
Pasithea Therapeutics (NASDAQ: KTTA) has announced promising preclinical data for its drug candidate PAS-004, a next-generation macrocyclic MEK inhibitor. The study, conducted at the Francis Crick Institute, demonstrated that PAS-004 outperforms FDA-approved MEK inhibitor selumetinib in inhibiting ETS2-driven inflammatory responses in IBD models. Key findings show PAS-004 achieved: - Superior suppression of ETS2 signaling across all tested doses - Significant reduction in ETS2-dependent functions - Higher normalized enrichment score (-3.96 vs -3.56) compared to selumetinib - Greater statistical significance (1.2 x 10⁻²⁵⁰ vs 3.7 x 10⁻⁷⁴) The results suggest PAS-004's potential as a treatment for inflammatory diseases like IBD and ankylosing spondylitis, with the ability to affect multiple cytokines including TNFα, IL-23, and IL-1β. The company reports favorable safety data from its Phase 1 clinical trial in advanced cancer patients.
