Study Summary

This trial is testing a new combination treatment of TAK-981 with pembrolizumab to see if it is safe and effective in treating people with advanced or metastatic solid tumors.

Who is the study for?
This trial is for adults with certain advanced or metastatic solid tumors that have relapsed or not responded to standard treatments. Eligible cancers include non-squamous and squamous NSCLC, cervical cancer, colorectal cancer (MSS-CRC), and cutaneous melanoma. Participants must have measurable disease, be in good physical condition (ECOG 0-1), have a heart function above a set threshold (LVEF ≥40%), recovered from previous therapy side effects, and adequate organ function.Check my eligibility
What is being tested?
The study tests TAK-981 combined with pembrolizumab on patients with specific solid tumors. The treatment involves cycles of 21 days each and can last up to two years unless there are reasons to stop earlier. Researchers want to see how safe this combo is, how well patients tolerate it, and if it effectively fights the cancer.See study design
What are the potential side effects?
Potential side effects may include reactions related to the immune system attacking normal organs (autoimmune reactions), infusion-related responses during drug administration, fatigue, digestive issues like nausea or diarrhea, blood cell count changes which could increase infection risk or cause anemia.
