NCT ID: NCT01024010

Last Updated: 2018-09-18

Results Overview

In Arm A: PCO, the primary endpoint of this trial is the percentage of complete responses. The NCI Working Group criteria was used to assess response to therapy: A Complete Response (CR) is briefly defines as the absence of lymphadenopathy, no heptomegaly nor splenomegaly, neutrophils greater than 1500/ul, platelets \> 100,000/ul, hemoglobin \>11.0 gm/dl, and peripheral blood lymphocytes \<4000uL.

PRIMARY outcome

Timeframe: 18 months

The primary endpoint Arm B: PCO+O is treatment-free survival rate at 18 months. An event for treatment-free survival will be defined as initiation of subsequent therapy for CLL or death due to any cause. All patients meeting the eligibility criteria who have signed a consent form and have begun treatment will be evaluable for event-free survival at 18 months. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true success proportion will be calculated.

SECONDARY outcome

Timeframe: 14 months

Population: All patients were evaluable for this endpoint.

The overall response rate will be estimated by the total number of complete or partial responses (CCR, CR, CRi, nPR, or PR) divided by the total number of evaluable patients. Responses will be evaluated using NCI Working Group criteria. Minimum requirements for a Partial Response (PR) requires: * 50% decrease in peripheral blood lymphocyte count from the baseline * 50% reduction in the sum of the products of the largest measured node or nodal masses on physical examination. * 50% reduction in size of liver and/or spleen * 50% improvement in neutrophils, platelets and hemoglobin

SECONDARY outcome

Timeframe: 14 months

Population: Thirty-one out of the 34 patients registered to Arm B: PCO+O began consolidation, 28 were evaluated for response at the end of consolidation treatment (3 patients did not return for response evaluation at the end of treatment).

The proportion of patients with an improvement in depth of response with the addition of ofatumumab consolidation after PCO induction will be estimated by the number of patients with improvement in response from the time of response evaluation at the completion of PCO to the time of response evaluation at the completion of ofatumumab consolidation divided by the total number of evaluable patients. The hierarchy for depth of response will be in the following increasing order: SD, PR, nPR, CR/CRi with MRD+, CR/CRi with MRD-. An improvement in depth of response will be defined as an improvement of at least one level in the hierarchy. Exact binomial 95% confidence intervals for the true overall improvement rate will be calculated.

Treatment-free survial is defined as the time from registration to the date of initiation of subsequent treatment for CLL or death due to any cause. The distribution of treatment-free survival will be estimated using the method of Kaplan-Meier.
