Pasithea Therapeutics Moves Forward with PAS-004 Phase 1/1b Trial

Pasithea Therapeutics Advances Phase 1/1b Study of PAS-004
Pasithea Therapeutics Corp. (NASDAQ: KTTA), a pioneering clinical-stage biotechnology company, is making headway in its research as it progresses to Cohort 2 of the clinical trial for PAS-004, an innovative macrocyclic MEK inhibitor, aimed at treating patients with neurofibromatosis type 1 (NF1). The decision to escalate the trial to the next dose level of 8 mg tablets came after a thorough evaluation by the external Safety Review Committee (SRC), which confirmed no significant safety concerns. This development marks a significant milestone in the clinical trial process for Pasithea.
Understanding the Phase 1/1b Clinical Trial
The ongoing Phase 1/1b clinical trial is designed to assess the safety and effectiveness of PAS-004 in adult patients diagnosed with NF1. This study aims to evaluate various aspects of the drug, including its tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy against symptomatic, inoperable plexiform neurofibromas (PNs). The initial data is anticipated in the first quarter of 2026, creating a buzz among the medical community and stakeholders.
Key Objectives of the Study
As part of the trial, participants will undergo a structured evaluation over a treatment cycle lasting 28 days. Among the primary aims is to identify a recommended dose that maximizes efficacy while ensuring safety. The trial includes multiple cohorts receiving varying doses of PAS-004—specifically 4 mg, 8 mg, 12 mg, and 18 mg—utilized in a 3+3 design framework. This approach helps determine the optimal dosage for future therapeutic applications.
Part A and Part B of the Trial Process
The study unfolds in two key parts. In Part A, up to 24 participants will be sequentially enrolled and treated with the doses mentioned, establishing the recommended phase 2 dose (RP2D). Subsequently, Part B will focus on a parallel enrollment of approximately 24 additional participants treated at the RPBD and one level below that for extended treatment cycles. This thorough design allows for a rich dataset to evaluate PAS-004's impact not just on tumor size but also on the quality of life of patients.
Growing Interest in PAS-004
CEO Dr. Tiago Reis Marques expressed enthusiasm about the trial's progress, revealing that enrollment is moving rapidly. With the first three patients already enrolled in Cohort 2, the demand for participation speaks volumes about the urgency surrounding effective treatments for NF1. Pasithea’s commitment to addressing unmet medical needs within this space underscores the potential of PAS-004.
Pioneering Biotechnology and Future Outlook
Pasithea Therapeutics is at the forefront of biotechnology, focusing not just on PAS-004 but a range of therapies that tackle RASopathies and MAPK pathway-driven cancers. The innovative approach surrounding PAS-004 indicates a robust pipeline that could redefine treatment protocols for NF1 and similar conditions.
In addition to patient safety and well-being, Pasithea is dedicated to improving the overall quality of life for those affected by these conditions. By meticulously exploring the impact of PAS-004 on symptom management and physical function, Pasithea aims to contribute positively to patients' day-to-day experiences.
Conclusion
As Pasithea Therapeutics (NASDAQ: KTTA) continues to navigate the complexities of clinical trials, it remains steadfast in its mission to bring breakthrough advancements in the treatment of NF1 and other significant health challenges. The recent SRC approval for advancing to the next cohort marks an essential step in a journey that promises new hope for patients and the medical community alike.
