Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

In the CLL2-BIO trial an allcomer CLL population with indication for treatment will be included.

Patient will receive 2 cycles of debulking treatment with bendamustin unless contraindications are existing or debulking is not indicated. Afterwards 6 cycles of induction therapy with ofatumumab and ibrutinib will be applied, each with a duration of 28 days. Primary endpoint overall Response rate will be assessed at final restaging.

Patients benefitting from BIO treatment will enter the maintenance phase of the trial. Maintenance treatment will be continued if no unacceptable toxicity occurs until three months after negativity of minimal residual disease (MRD) is achieved in peripheral blood in patients with (clinical) complete response (CR) or (clinical) incomplete complete response (CRi) confirmed by 2 consecutive testings of MRD within 3 months, progression of CLL, start of a subsequent therapy or up to 8 cycles of maintenance (each cycle with a duration of 84 calendar days = 3 months), whichever occurs first.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
