NCT ID NCT05371964

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

Summary

This early-stage trial tests two drugs—imetelstat and ruxolitinib—together in people with myelofibrosis, a type of bone marrow cancer. The study has two parts: first, finding a safe dose of the combination, and second, checking if it improves symptoms like fatigue and spleen discomfort. About 36 adults with intermediate or high-risk myelofibrosis are being recruited.
