An Observational Study to Evaluate the Clinical and Biologic Features and Outcome of Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) Treated With Venetoclax-based Regimens Outside Clinical Trials in Italy

Observational study aimed at describing the characteristics and outcome of CLL patients who started treatment with venetoclax-based regimens according to the local label outside clinical trials in Italy in a period of time ranging from the start of the Venetoclax Named Patient Program (March 2016) until June 30th, 2025.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Observational study to describe the characteristics and outcome of CLL patients treated with venetoclax according to the local label. The study includes two different groups: a retrospective group (all patients who have received at least one dose of venetoclax before enrolment) and a prospective group (patients receiving treatment with venetoclax after enrolment). All patients in both groups will be observed for up to 48 months from the treatment start. In the prospective cohort only, QoL and treatment adherence will be assessed at the time of study entry (i.e. baseline) and thereafter at 3, 6, 9, 12, 18 24, 30, 36, 42 and 48 months of follow-up and at treatment discontinuation (due to any cause).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
