Pasithea Therapeutics Announces PAS-004 Abstract Accepted for Poster Presentation at 2024 ASCO Annual Meeting
Pasithea Therapeutics Corp. (NASDAQ: KTTA) announced the acceptance of an abstract for poster presentation at the 2024 ASCO Annual Meeting for their drug PAS-004, a macrocyclic MEK inhibitor targeting neurofibromatosis type 1 (NF1) and other indications. The drug is the first of its kind in human clinical trials, offering extended half-life for improved efficacy.
PAS-004, a novel macrocyclic MEK inhibitor, has been accepted for poster presentation at the 2024 ASCO Annual Meeting, showcasing its potential in inhibiting cancer cell growth and tumor growth.
The drug is the first macrocyclic MEK inhibitor to enter human clinical trials, offering an expected extended half-life that may enhance compliance rates and efficacy in treating NF1.
Macrocycles like PAS-004 are known for stronger binding, better solubility, and longer half-life, potentially resulting in more selective and less off-target effects compared to acyclic small molecules.
- None.
SOUTH SAN FRANCISCO, Calif. and MIAMI, April 29, 2024 (GLOBE NEWSWIRE) -- Pasithea Therapeutics Corp. (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 indications, today announced the acceptance of an abstract for poster presentation at the American Society of Cancer Oncology (“ASCO”), which will be held in Chicago from May 31 – June 4, 2024.
Session titles and information for the abstract are listed below and now available on the ASCO online program planner.
PAS-004: A novel macrocyclic MEK inhibitor to inhibit cancer cell growth in vitro and tumor growth in mouse xenograft studies.

The poster will be available at www.pasithea.com/publications following the presentation.
PAS-004 is the first macrocyclic MEK inhibitor to enter human clinical trials, with an expected extended half-life which may provide better compliance rates, as well as improved efficacy in NF1. Macrocycles are known to exhibit stronger binding, better solubility and longer half-life with more selectivity and less off target effect as compared to acyclic small molecules.
About PAS-004
PAS-004 is a small molecule allosteric inhibitor of MEK 1/2, which are dual-specificity protein kinases, in the MAPK signaling pathway. The MAPK pathway has been implicated in a variety of diseases, as it functions to drive cell proliferation, differentiation, survival and a variety of other cellular functions that, when abnormally activated, are critical for the formation and progression of tumors, fibrosis and other diseases. MEK inhibitors block phosphorylation (activation) of extracellular signal-regulated kinases (ERK). Blocking the phosphorylation of ERK can lead to cell death and inhibition of tumor growth. Existing FDA approved MEK inhibitors are marketed for a range of diseases, including certain cancers and neurofibromatosis type 1 (NF1). We believe these MEK inhibitors suffer from certain limitations, including known toxicities. Unlike current FDA approved MEK inhibitors, PAS-004 is macrocyclic, which we believe may lead to improved pharmacokinetic and safety (tolerability) profiles. Cyclization offers rigidity for stronger binding with drug target receptors. PAS-004 was designed to provide a longer half-life with what we believe is a better therapeutic window. Further, we believe the potency and safety profile that PAS-004 has demonstrated in preclinical studies may also lead to stronger and more durable response rates and efficacy, as well as better dosing schedules. PAS-004 has been tested in a range of mouse models of various diseases and has completed preclinical testing and animal toxicology studies. Additionally, PAS-004 has received orphan-drug designation from the FDA for the treatment of NF1.
