Summary

This trial will test the safety and effectiveness of a drug called NST-628 in adult patients with advanced solid tumors that have specific genetic mutations. The study will be done in two parts and will focus on

Who is the study for?

This trial is for adults with advanced solid tumors that have mutations in the MAPK pathway and who've run out of standard treatment options. It's open to those over 18 or at legal consent age, with certain types of genetic alterations like NRAS or BRAF mutations, and requires a confirmed diagnosis through tissue samples.

What is being tested?

The study tests NST-628 oral tablets' safety and effectiveness on patients with specific solid tumors. It's an early-stage (Phase 1), non-randomized trial where all participants receive multiple doses of NST-628 to assess its impact on their cancer.

What are the potential side effects?

Since this is a Phase 1 trial primarily focused on safety and dosage levels, specific side effects are not listed but may include typical reactions seen in cancer treatments such as fatigue, nausea, skin changes, or other organ-specific issues.

Experimental Treatment

Group I: Part A Dose Escalation and Part B Dose ExpansionExperimental Treatment1 Intervention

Part A will evaluate the safety of NST-628 with advanced solid tumors and determine the recommended dose for expansion of NST-628. Part B will evaluate the objective tumor response rate in subjects with advanced solid tumors harboring specified genetic alterations receiving NST-628 and evaluate the safety of NST-628 in subjects with advanced solid tumors in cohorts defined below: i. Melanoma Cohorts 1. Activating NRAS mutations 2. Select BRAF alterations ii. Non-Melanoma Cohorts: 1. Solid tumors with NRAS activating mutations 2. Solid tumors with KRAS activating mutations 3. Solid tumors with select BRAF alterations 4. Glioma with BRAF alterations
