Connected Blood Pressure Monitoring in Patients With Hematologic Malignancies Initiating Covalent BTK Inhibitors

Scientific justification:

Oral anticancer therapies, including cBTKi such as ibrutinib, acalabrutinib, and zanubrutinib, have transformed the treatment of various lymphoid malignancies. However, BTKi are associated with a high incidence of hypertension, reported in 20-70% of cases. Early and reliable detection is essential to avoid cardiovascular toxicity and prevent therapy discontinuation. In clinic blood pressure assessments are often limited by white-coat effect and lack of reproducibility, whereas home BP monitoring improves diagnostic accuracy and patient engagement. Despite this, there is no standardized BP monitoring strategy for patients with cBTKi.

Intervention/strategy description:

All participants will receive a validated connected blood pressure monitor and standardized training on appropriate measurement procedures. BP values will be automatically transmitted to a secure platform monitored daily by an Advanced Practice Nurse (IPA), who will ensure adherence, verify data quality, and coordinate clinical interventions when necessary.

Follow-up description:

At inclusion, patients will undergo an IPA consultation, a cardio-oncology consultation, and a medication reconciliation visit. Follow-up medical visits will be scheduled at 1, 4, and 6 months. Phone calls will be made by IPA at week 1, week 2, week 3, week 6, month 3, and month 5 to assess compliance, symptoms, and concomitant therapies. Daily connection to the monitoring platform will allow continuous verification of BP measurements and early detection of hypertension.
