What this trial studies

This multicenter observational study evaluates the effectiveness of Orelabrutinib in patients with Chronic Lymphocytic Leukemia (CLL) and Small Cell Lymphoma (SLL). Participants will receive Orelabrutinib for 12 cycles, with primary endpoints focusing on the incidence of grade 3 hypertension and atrial fibrillation. Secondary endpoints include improvements in abnormal markers, overall response rate (ORR), complete response (CR), progression-free survival (PFS), and overall survival (OS). The study aims to gather real-world data on the safety and efficacy of this treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 with confirmed CLL/SLL and specific health criteria.

Not a fit: Patients with severe organ dysfunction or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety and effectiveness of Orelabrutinib for patients with CLL/SLL.

How similar studies have performed: Other studies have shown promising results with similar treatments, indicating potential for success in this approach.
