The objectives of this study were to assess the activity and tolerability of ibrutinib and rituximab in combination, in high-risk CLL patients. The study included 40 patients with CLL, with a median of two prior therapies. Twenty of the patients had del 17p mutations and 13 patients had del11q. Thirty-four patients (85%) achieved a partial response (PR), and four (10%) achieved a complete response (CR), leading to an ORR of 95%. One of four CRs were negative for minimal residual disease (MRD) by flow cytometry.
The most common AEs related to treatment, all grade 1 or 2, were diarrhea (n=17), bruising/rash (n=14), arthalgia (n=13), nausea/acid reflux (n=10) and upper respiratory infection (n=9). The most common grade 3 or higher AEs related to treatment were lung infection (n=4), peripheral neuropathy (n=3), neutropenia (n=2), mucositis (n=2) and increased ALT (n=1).
Questionnaires revealed improved overall health and quality of life after 6 months, based on Quality of Life questionnaire (EORTC-QOL-v.3), with 89% of patients reporting a high quality of life score (6 to 7) compared to 46% at baseline and patients achieved a statistically significant increase in body weight.
