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

An Economic Analysis of Early vs Delayed Therapy in Newly Diagnosed Asymptomatic High-Risk Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Companion Analysis to CCTG CLC.3/SWOG 1925 Randomized Phase III Clinical Trial

Sponsor

Canadian Cancer Trials Group

Enrollment

247 participants

Start Date

Jan 27, 2023

Study Type

OBSERVATIONAL

Conditions

Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma

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.

Eligibility

Min Age: 18 Years

Inclusion Criteria4

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.

Interventions

OTHEREQ-5D-5L Instrument

This instrument is a measure of health status for use in evaluating health and healthcare.

OTHERWork Productivity and Daily Activity Impairment (WPAI) survey

The questionnaire includes three open-ended questions that determines: 1) hours absent from work due to health problems; 2) hours absent from work due to other reasons; and (3) hours actually worked over the past 30 days. Additional questions ask about the impact of health problems on work productivity and daily activities and are scored along a vertical visual analog scale. The WPAI provides estimates on absenteeism, presenteeism, global measures of lost productivity (absenteeism+presenteeism) and daily activity impairment (impaired ability to perform non-work activities including work around the house, child care, exercise, studying, and leisure activities)

OTHERResource Utilization Form (SMRC)

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.
