Trial Outcomes & Findings for Alemtuzumab (Campath) to Treat T-Large Granular Lymphocyte Leukemia (NCT NCT00345345)

NCT ID: NCT00345345

Last Updated: 2022-05-03

Results Overview

The primary endpoint was hematologic response at three months after treatment. A complete response (CR) was defined as normalization of all affected lineages, and a partial response (PR) was defined in neutropenic subjects as 100% increase in the ANC to \>500/µL, and in those with anemia, any increase in hemoglobin of 2 g/dL or more observed in at least two serial measurements 1 week apart and sustained for one month or more without exogenous growth factors support or transfusions.

PRIMARY outcome

Timeframe: 3 months

Population: The analyses included only those subjects who were given Alemtuzumab. Analysis was by intention to treat.

The primary endpoint was hematologic response at three months after treatment. A complete response (CR) was defined as normalization of all affected lineages, and a partial response (PR) was defined in neutropenic subjects as 100% increase in the ANC to \>500/µL, and in those with anemia, any increase in hemoglobin of 2 g/dL or more observed in at least two serial measurements 1 week apart and sustained for one month or more without exogenous growth factors support or transfusions.

Population: Analysis was by intention to treat.

Number of participants that experienced a Life-Threatening Toxicity (grade \>/= 4) as defined by Common toxicity Criteria (CTC) version 2.0. The CTC 2.0 is a set of criteria for the standardized classification of adverse effects. Adverse events are graded accordingly: 0 = No adverse event or within normal limits 1 = Mild adverse event 2 = Moderate adverse event 3 = Severe and undesirable adverse event 4 = Life-threatening or disabling adverse event 5 = Death related to adverse event
