The Company will present updated interim clinical data from its onging Phase 1 clinical trial of PAS-004 in patients with MAPK pathway driven advanced solid tumors.
"We are pleased to present interim clinical data of PAS-004 through cohort 4A and 4B, that to date has demonstrated clinical activity, target engagement, and a favorable safety profile," said Dr. Tiago Reis Marques, Chief Executive Officer of Pasithea. "We believe PAS-004’s emerging profile may achieve the sweet spot between PK, PD and tolerability and may make PAS-004 an ideal candidate for the treatment of NF1 related cutaneous and plexiform neurofibromas as well as a potential candidate for treatment of various cancers and MAPK pathway driven diseases."
