ClinConnect Summary

This clinical trial is studying a new treatment called CK0804, which is being tested as an additional therapy for people with myelofibrosis who are not getting enough benefit from their current medication, ruxolitinib. Myelofibrosis is a type of blood cancer that affects the bone marrow, and this study aims to see if CK0804 can help improve patients' health and manage their symptoms better. The trial is currently looking for participants aged 18 and older who have been on ruxolitinib for at least three months but are still experiencing symptoms or issues related to their condition.

Participants in the trial will receive CK0804 and will be closely monitored for safety and how well they tolerate the treatment. To be eligible, participants must have a life expectancy of more than six months and must have specific health conditions related to myelofibrosis. It’s important for potential participants to understand the requirements, including avoiding pregnancy during the study. Overall, this trial hopes to find a better treatment option for those who are not receiving adequate relief from their current medication.
