International CML Foundation (iCMLf) Directors recommendation:

The International CML Foundation (iCMLf) Directors includes and additional topic on monitoring procedures for CML patients under long-term therapy:

All TKI have the capacity to prolong the QTc interval and strongly interact with drugs such as chloroquine and azithromycin, 2 drugs that are currently evaluated against COVID-19. Combining these medications with TKI in the absence of medical prescription and supervision may lead to fatal torsade de pointe.
