Could a lifesaving leukemia drug harm Men's sexual health?
NCT ID NCT07061145
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study looks at whether tyrosine kinase inhibitors (TKIs), the standard treatment for chronic myeloid leukemia (CML), might be linked to erectile dysfunction (ED) in men. Researchers will track 350 male patients who started TKI therapy, using questionnaires and medical records to see how many develop ED and whether the type of TKI matters. The goal is to better understand the long-term side effects of these drugs and potentially improve patient care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tyrosine kinase inhibitors (TKIs) such as imatinib, dasatinib, nilotinib, bosutinib, or ponatinib, given as standard care for chronic myeloid leukemia.
- What this could lead to
- If a link is confirmed, it could lead to better monitoring and management of erectile dysfunction in men taking TKIs, improving quality of life and potentially aiding early detection of cardiovascular risk.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. The results may be influenced by other factors, and the findings might not apply to all patients.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Adult male patients (aged 18-75) diagnosed with chronic-phase Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML), who initiated frontline treatment with tyrosine kinase inhibitors (TKIs) between January 1, 2015, and January 31, 2022. Patients must not have experienced erectile dysfunction (ED) before TKI initiation. Both retrospective and prospective clinical data will be collected to assess the occurrence and characteristics of ED and related cardiovascular events.
