First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new drug called JMT203 in people with lung, pancreatic, or colorectal cancer who are experiencing cachexia (severe weight loss and muscle wasting). The drug is an antibody that targets a protein linked to appetite loss. The trial will enroll about 307 participants and will first check safety and dosing, then measure if it helps patients gain weight over 12 weeks.
