Study Summary

This trial tests a new drug combination to see if it's safe and effective in treating advanced or metastatic solid tumors.

Who is the study for?
Adults with advanced or metastatic solid tumors who've tried all other treatments can join this trial. They must have a tumor sample, measurable disease for assessment, and agree to biopsies. Women of childbearing potential and men must follow strict contraception guidelines. People with HIV can join if it's well-controlled.Check my eligibility
What is being tested?
The study is testing MK-6598 alone and combined with Pembrolizumab in adults with advanced solid tumors to find the safest dose that works best (RP2D). Participants will be assessed for how their tumors respond to these treatments.See study design
What are the potential side effects?
Possible side effects include reactions similar to those seen with monoclonal antibody therapies such as severe allergies, lung issues like pneumonitis, liver problems like hepatitis B or C reactivation, immune system complications leading to conditions like autoimmune diseases.

Answered by AI

To what extent is the enrollment of participants open for this study?

"Affirmative. The information on clinicaltrials.gov displays that this research trial is currently recruiting participants, with a first posting date of December 21st 2022 and the most recent update being January 6th 2023. This investigation requires 90 enrollees from 1 site to complete the study."

Answered by AI

What are the projected results of this medical experiment?

"According to the trial sponsor Merck Sharp & Dohme LLC, this clinical study will last for up to 21 days and aims to measure how many participants discontinue due to an adverse event. Secondary endpoints include measuring minimum serum concentration of MK-6598 through pre-dose blood samples and post-dose multiple time points, tumor phenylpyruvate concentrations from similar measurements, as well as maximum serum concentration of MK-6598 via a comparable method."
