Plain-language summary

This study is evaluating the safety and effectiveness of combining TQ05105 tablets with TQB3617 capsules to treat myelofibrosis, a bone marrow disorder. It enrolls patients aged 18 and older with primary myelofibrosis, or myelofibrosis that developed after polycythemia vera or essential thrombocythemia, classified as intermediate or high risk. The study is being conducted in Phase 1/Phase 2 and is currently recruiting participants.
