(NASDAQ: KTTA) (“Pasithea” or the “Company”), a clinical-stage biotechnology company developing PAS-004, a next-generation macrocyclic MEK inhibitor, for the treatment of neurofibromatosis type 1 (NF1) and other cancer indications, today announced safety, tolerability, pharmacokinetic (PK) and preliminary efficacy data from the first 2 cohorts of patients (n=6) in its Phase 1 clinical trial of PAS-004, being conducted at four clinical sites in the United States. The Phase 1 clinical trial is a multi-center, open-label, dose escalation 3+3 study design to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and preliminary efficacy of PAS-004 in patients with MAPK pathway driven advanced solid tumors with a documented RAS, NF1 or RAF mutation or patients who have failed BRAF/MEK inhibition (NCT06299839). “We are very pleased to share the PK, safety, and preliminary efficacy data from the 2 mg and 4 mg cohorts in our first-in-human Phase 1 clinical trial of PAS-004. We believe these data demonstrate a PK and safety profile that differentiates PAS-004 as a next-generation MEK inhibitor. We have already achieved significant PAS-004 exposures with a favorable safety profile and have not seen adverse side effects such as rash or GI toxicity, which are typical for MEK inhibitors even at low doses. The long half-life at approximately 70 hours, and the ability to achieve a flat PK curve at steady-state, aim to provide a constant target inhibition while avoiding peak plasma toxicities, which is a unique PK profile among MEK inhibitors used for the treatment of Neurofibromatosis t...
