Study Summary

This trial is studying the recommended dosage of a combination of imetelstat and ruxolitinib to treat myelofibrosis, as well as the safety and effectiveness of this dosage.

Who is the study for?

This trial is for adults with a condition called myelofibrosis, who are either already on ruxolitinib treatment or haven't been treated with JAK inhibitors. They should have symptoms like an enlarged spleen or other related issues and must not be candidates for stem cell transplant. Participants need to meet certain blood and biochemical test criteria, have a performance status score of 0-2, and agree to use contraception.Check my eligibility

What is being tested?

The study tests the combination of two drugs: Imetelstat and Ruxolitinib in people with myelofibrosis. The first part determines the best dose of Imetelstat when used with Ruxolitinib, while the second part assesses safety and how well this combined dose works.See study design

What are the potential side effects?

Possible side effects include reactions at the injection site, changes in blood counts leading to increased risk of infections or bleeding, liver problems, fatigue, shortness of breath, gastrointestinal issues such as nausea or diarrhea.

Experimental Treatment

Group I: Imetelstat + RuxolitinibExperimental Treatment2 Interventions

Part 1: Participants who have received ruxolitinib orally (PO) as part of standard of care (SOC) for at least 12 weeks prior to Screening will be enrolled. After enrollment, participants will initiate imetelstat therapy. Dose levels of imetelstat may include 4.7, 6, 7.5, 9.4mg, until a RP2D is established. Part 2: Janus kinase (JAK) inhibitor naïve participants will receive initial treatment with ruxolitinib for at least 12 weeks, including 4 weeks at a stable dose, followed by imetelstat treatment at the RP2D in combination with ruxolitinib.
