What this trial studies

This is a national, multicenter observational study with retrospective and prospective parts that follows adult men with chronic‑phase Philadelphia chromosome–positive CML who started frontline TKI therapy between January 1, 2015 and January 31, 2022. Retrospective data will be collected from medical records on ED onset, cardiac tests, lab results, and BCR-ABL levels, and participants will be followed prospectively for up to 24 months to monitor new ED, cardiovascular events, and resolution after stopping therapy. The study compares incidence across TKIs (imatinib, dasatinib, nilotinib, bosutinib, ponatinib) and explores links between ED and cardiovascular toxicity as well as reversibility in patients who reach treatment‑free remission. No extra tests beyond routine clinical care are required, and about 350 patients are expected to be enrolled.

Who should consider this trial

Good fit: Adult men (aged 18–75) with chronic‑phase Ph+ or BCR‑ABL+ CML who started frontline TKI therapy between 01‑Jan‑2015 and 31‑Jan‑2022 and who did not have ED before starting TKIs are ideal candidates.

Not a fit: Patients in accelerated or blastic phase CML, men who had erectile dysfunction before starting TKI therapy, women, or those outside the specified treatment dates are unlikely to benefit from this study's findings.

Why it matters

Potential benefit: If successful, the study could clarify whether specific TKIs increase ED risk and help doctors counsel patients and choose therapies with fewer sexual side effects.

How similar studies have performed: Some case reports and small series have noted sexual side effects with TKIs, but large, systematic observational studies on ED incidence with modern TKIs are limited.
