Economic Analysis of Early vs Delayed Therapy in Newly Diagnosed Asymptomatic High-Risk Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma:

Recruiting

• Conditions: Chronic Lymphocytic Leukemia; Small Lymphocytic Lymphoma

• Registration Number: NCT05371808
• Lead Sponsor: Canadian Cancer Trials Group

Brief Summary

Utilization data will be collected from all patients entered on the trial at Canadian centres from the time of registration until death, removal from study, or completion of 10 years of follow-up.

Protocol-specified health care utilization will be collected within trial case report forms, and will include study visits, radiographic assessments, laboratory investigations, and treatment administration.

Resource utilization data collection will be supplemented by a self-administered resource utilization form (Stanford SMRC) to document non-protocol specified utilization. This will include hospitalizations (including days in hospital), emergency room visits, and non-protocol specified ambulatory visits.

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 247

Inclusion Criteria

• Patient must be eligible for the core CLC3/S1925 protocol.
• Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.
• Patient is able (i.e. sufficiently fluent) and willing to complete the quality of life and/or health utility questionnaires in either English or French. The baseline assessment must be completed within required timelines, prior to enrollment. Inability (lack of comprehension in English or French, or other equivalent reason such as cognitive issues or lack of competency) to complete the questionnaires will not make the patient ineligible for the study. However, ability but unwillingness to complete the questionnaires will make the patient ineligible.
• Patients must be accessible for treatment and follow-up. Investigators must assure themselves the patients enrolled on this trial will be available for complete documentation of the treatment, adverse events, and follow-up.

Primary Outcome Measures

Name	Time	Method
To determine incremental cost-utility ratio of an early novel therapy approach compared to a deferred approach in Canadian patients with high-risk CLL (enrolled in the randomized component of the SWOG S1925/CLC3 study).	10 years	Direct medical costs will be estimated from the perspective of the Canadian public healthcare system. The denominator of the ratio will be expressed in quality-adjusted life years gained.

Secondary Outcome Measures

Name	Time	Method
To determine the incremental cost-effectiveness ratio of an early novel therapy approach compared to a deferred approach in Canadian patients with high-risk CLL. Effectiveness will be expressed in years prior to second progression gained.	10 years
To compare the lost productivity for Canadian individuals with high-risk CLL randomized to an early treatment approach compared to a deferred approach	10 years
To determine incremental cost-effectiveness ratio of an early novel therapy approach compared to a deferred approach in Canadian patients with high-risk CLL . Effectiveness will be expressed in life years gained	10 years
To determine the direct medical costs associated with the care of Canadian high-risk CLL patients randomized to an early treatment approach compared to a deferred approach.	10 years
To compare the change in health preference (utility) over time for individuals with high-risk CLL randomized to an early approach vs. deferred treatment approach	10 years
