Phase 1 Study of Oral NST-628 Tablets to Test Safety and Effectiveness in Adults with Advanced Solid Tumors Having MAPK Pathway or Other Genetic Mutations

What this Trial Is About

Researchers are evaluating the safety, pharmacokinetics, and preliminary effectiveness of NST-628, an oral drug targeting the MAPK pathway, in adults with advanced solid tumors that have specific genetic mutations and have exhausted standard treatments. This Phase 1, open-label, multi-center study includes patients with tumors dependent on the MAPK pathway, such as melanoma and glioma, aiming to find a suitable dose and observe tumor responses. The study has two parts Part A involves dose escalation where increasing doses of NST-628 are given once daily in 28-day cycles to determine the maximum tolerated dose and the recommended dose for expansion. Part B involves dose expansion with several cohorts of patients harboring specific MAPK pathway mutations receiving the recommended dose to further assess safety and tumor response. Dose adjustments may be made based on observed effects. Participants will undergo regular assessments including safety evaluations, tumor response measurements using standardized criteria, and pharmacokinetic analyses throughout the study, which lasts about one year on average for primary outcomes and up to two years for survival monitoring. Tumor tissue samples are required, and patients will be followed until the last visit of the final participant. Safety, tumor response, progression-free survival, overall survival, and drug behavior in the body are key outcomes measured.
