Trial Outcomes & Findings for Imprime PGG, Alemtuzumab, and Rituximab in Treating Patients With High Risk Chronic Lymphocytic Leukemia (NCT NCT01269385)

NCT ID: NCT01269385

Last Updated: 2020-06-23

Results Overview

MTD is defined as the dose level below the lowest dose that induces dose-limiting toxicity (DLT) in at least one-third of patients (at least 2 of a maximum of 6 new patients). A total of 6 patients treated at the MTD will be sufficient to identify common toxicities at the MTD. Three patients will be treated at a given dose level combination for at least 5 weeks to assess toxicity. If dose-limiting toxicity (DLT) is not seen in any of the 3 patients, 3 new patients will be accrued and treated at the next higher dose level. If DLT is seen in 2 or 3 of 3 patients treated at a given dose level, then the next 3 patients will be treated at the next lower dose level, if only 3 patients were enrolled and treated at this lower dose level. We tabulate the number of patients reporting a DLT.

SECONDARY outcome

Timeframe: 3 months after the completion of treatment, up to 5 years

Population: All patients treated at dose level 2 were included in this analysis. This includes 6 patients registered to the Phase I: Dose level 2 and 8 patients registered to Phase II.

Overall response rate was estimated by the total number of patients receiving Dose Level 2 reporting complete responses or partial responses (CR or PR) divided by the total number of evaluable patients that started Dose Level 2 treatment. A COMPLETE RESPONSE (CR) requires all of the following for a period of at least 2 months: Absence of lymphadenopathy by physical examination, no hepatomegaly or splenomegaly, absence of constitutional symptoms, neutrophils \>1500/ul, Platelets \>100,000/ul, Hemoglobin \>11.0 gm/dl, Peripheral blood lymphocytes \<4000/uL. A PARTIAL RESPONSE (PR) requires the patient exhibits at least two of the features: ≥ 50% decrease in peripheral blood lymphocyte count from baseline, ≥ 50% reduction in the sum of the products of the maximal perpendicular diameters of the largest measured node or nodal masses in the right and left cervical, axillary, and inguinal lymph node regions on physical examination.

Timeframe: Up to 5 years

Population: All 20 eligible patients that started and completed protocol treatment were combined in this analysis to assess overall benefit of protocol treatment.

Time to disease progression is defined as the time from registration to the earliest date of documentation of disease progression. If a patient dies without a documentation of disease progression, the patient will be considered to have had tumor progression at the time of their death unless there is sufficient documented evidence to conclude no progression occurred prior to death. The distribution of time to disease progression will be estimated using the method of Kaplan-Meier.

Timeframe: Up to 5 years

Population: Data was not collected to run this analysis.

Duration of response is defined for all evaluable patients who have achieved an objective response as the date at which the patient's objective status is first noted to be either a CR or PR to the earliest date progression is documented. The distribution of duration of response will be estimated using the method of Kaplan-Meier.
