Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will enroll patients initiating Bruton Tyrosine Kinase (BTK) inhibitors without history of documented arrhythmia while on therapy using the Medtronic LINQ-2 insertable cardiac monitor (ILR). The incidence of new onset atrial fibrillation (AF) and other arrhythmia will be determined. Actions taken in response to device detected arrhythmia will be recorded.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This single arm, prospective non-blinded study will enroll 50 patients initiating treatment with BTK inhibitors (ibrutinib, acalabrutinib, zanubrutinib or pirtobrutinib) without documented arrhythmia prior to starting BTK inhibitor therapy, without contraindications to an implanted loop recorder (ILR). They will be offered the option of monitoring arrhythmias using the Medtronic LINQ-2 insertable cardiac monitor (ILR). Monitoring data will be collected prospectively until the patient withdraws consent, the device is removed, or up to 60 months. Investigators hope to obtain information on arrhythmia incidence including AF, ventricular arrhythmia (VA), and actions taken in response to awareness of such episodes.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients initiated on Bruton tyrosine kinase inhibitors, consenting to installment of ILR

Patients free of documented arrhythmia initiating treatment with a BTK inhibitor who consent to monitoring using the Medtronic LINQ-2 implanted cardiac monitoring device (ILR) prior to initiating BTK inhibitor therapy.

Group Type OTHER

Medtronic LINQ-2 Insertable Cardiac Monitor (ILR)

Intervention Type DEVICE

Patients initiating BTK inhibitors will be offered the option of monitoring using the Medtronic Insertable Cardiac Monitor (ILR). The device will be implanted by a certified and credentialed electrophysiologist to enable monitoring to begin at least 24 hours prior to the first administration of the BTK inhibitor. Monitoring data will be collected prospectively until the patient withdraws consent, the device is removed, or up to 60 months
