Study Summary

This trial is testing a new drug (TTX-080) to see if it is safe and effective in treating cancer. The drug is being tested alone and in combination with two other drugs (pembrolizumab and cetuximab) to see if it improves treatment.

Who is the study for?
This trial is for adults with advanced or metastatic cancer who are in fairly good health (able to perform daily activities without significant assistance) and have a life expectancy of at least 12 weeks. They must be able to consent to the study, not have severe allergies to treatment components, no recent use of other investigational drugs, no high-dose steroids or immunosuppressants, and no uncontrolled illnesses.Check my eligibility
What is being tested?
The TTX-080 clinical trial is testing the safety and optimal dosing of a new drug called TTX-080 alone or combined with pembrolizumab or cetuximab in patients with resistant cancers. It's an early-phase study where researchers gradually increase doses to find what's safe and potentially effective.See study design
What are the potential side effects?
Possible side effects include allergic reactions related to the treatments' components, immune system-related issues due to HLA-G inhibition by TTX-080, infusion reactions from monoclonal antibodies like pembrolizumab/cetuximab, fatigue, skin reactions from EGFR inhibition by cetuximab.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
1. To determine the anti-tumor activity of TTX-080 by objective response rate [complete response + partial response) for each tumor arm per RECIST 1.1
Secondary outcome measures
AUC(0-Inf): Area Under the Plasma Concentration-time Curve From Zero to Infinity for TTX-080
AUC(0-t): Area Under the Plasma Concentration-time Curve From Zero Time to the Last Measurable Point for TTX-080
Adverse events (AEs) as characterized by the incidence, type, frequency, severity (graded according to NCI-CTCAE v5.0), timing, seriousness, and relationship to investigational product, and/or combination therapy, and/or individual approved therapies
