Adherence, persistence and efficacy of dasatinib and nilotinib in the treatment of patients resistant or intolerant to imatinib with chronic myeloid leukemia in chronic phase: an Italian multicenter study over two years in real life.

BACKGROUND: The use of dasatinib and nilotinib in the treatment of patients with chronic myeloid leukemia represents a valid therapeutic option for patients resistant or intolerant to imatinib. In this multicentre study, adherence, persistence and efficacy in real life over two years of treatment were evaluated. MATERIALS AND METHODS: Adherence to treatment was calculated as the ratio between the dose received and the prescribed dose. The dose received was calculated using pharmacy refill data. The persistence with treatment was calculated as the difference between the end and the beginning of the treatment. Efficacy was assigned as Progression-Free Survival (PFS) and Events-Free Survival (EFS) and represented through the Kaplan-Meier curve. RESULTS: The number of patients analysed was 117, 70 treated with dasatinib and 47 with nilotinib. Adherence to treatment for dasatinib and nilotinib at two years was 0.91 and 0.82 respectively. Persistence at two years was 77% while the PFS was 92% for both drugs in the study. CONCLUSION: Adherence to the treatment calculated over two years showed a superiority of dasatinib over nilotinib. Nevertheless, the efficacy in terms of PFS and EFS is superimposable between the two drugs in the study.

Patient associations and clinical oncology research: how much does a patient's voice really matter?

Background: New trends are emerging in clinical research, such as patient empowerment and an active role in influencing health and research ethics. Patients' involvement is considered pivotal by stakeholders and institutions because they can channel the voice of those they represent, empowering their starring role in the different research activities.Objectives: To obtain an overview of the real involvement of Italian patient associations in clinical research.Methods: In January 2019, the Working Group 'Clinical Research Coordinators' of the Italian Association of Medical Oncology spread an online questionnaire consisting of 16 questions on the active involvement of patient associations in clinical research.Results: The involvement in clinical research working groups, in the organization and implementation of specific activities and training initiatives is very limited (21.7% in both cases), as well as the active involvement in the conduct and/or definition of clinical trials (0.3%). Moreover, few associations (15.2%) have joined projects on patient involvement in clinical research in collaboration with other associations.Discussion: Although the current involvement of the associations may have been somewhat underestimated, there is no doubt that much more can be done in terms of training and identification of common objectives between patients and professionals.
