Study of PAS-004 for Advanced Solid Tumors with Specific Mutations

This study is testing a new medication called PAS-004 in people with advanced solid tumors that have specific genetic changes (mutations) in RAS, NF1, or RAF genes. PAS-004 is a type of drug called a MEK 1/2 inhibitor, which works by blocking certain signals that can help cancer cells grow. The main goals are to find out how well people can tolerate different doses of PAS-004 and what side effects it might cause. You would take PAS-004 by mouth once a day. The study plans to enroll 48 participants aged 18 or older. To join, you need to have one of the specific mutations (BRAF or NF1) in your tumor.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It aims to enroll 48 participants.
What's involved
You will have regular visits with the study doctor, and undergo tests and exams to check your health and safety. You will take PAS-004 by mouth once a day in 28-day cycles.
Compensation
Not stated in the trial record.
Follow-up
Your health and any side effects will be monitored for 30 days after you stop taking PAS-004.

  • Evaluation of dose limiting toxicities (DLTs)Day 1 through Day 35 (Cycle 1)

    Pre-defined DLTs will be assessed for dose escalation and expansion determinations.

  • Evaluation of adverse events (AEs)Screening through Day 1 through Day 35 (Cycle 1), and 30 days after discontinuation of study drug

    The number and severity of AEs will be evaluated for dosing cohorts to inform dose escalation and expansion decisions, and support selection of a preliminary recommended phase 2 dose (RP2D).

  • Evaluation of AEs leading to discontinuation of investigational product (IP), PAS-004.Screening through Day 1 through Day 35 (Cycle 1), and 30 days after discontinuation of study drug

    The number and severity of AEs leading to discontinuation of study drug will be evaluated for dosing cohorts to inform dose escalation and expansion decisions, and support selection of a preliminary recommended phase 2 dose (RP2D).

  • Evaluation of hematology laboratory parametersScreening through Day 1 through Day 35 (Cycle 1), and 30 days after discontinuation of study drug

    Lab parameters will be evaluated for to assess the safety profile of the study drug, and support selection of a preliminary recommended phase 2 dose (RP2D).

  • Evaluation of clinical chemistry laboratory parametersScreening through Day 1 through Day 35 (Cycle 1), and 30 days after discontinuation of study drug

    Lab parameters will be evaluated for to assess the safety profile of the study drug, and support selection of a preliminary recommended phase 2 dose (RP2D).
