Trial Outcomes & Findings for Study of Low-Intensity Conditioning for Allogeneic Stem Cell Transplant (NCT NCT00143845)

NCT ID: NCT00143845

Last Updated: 2017-03-08

Results Overview

The primary objective of this study was to establish the rate of acute GVHD following prophylactic cellular immunotherapy after allogeneic hematopoietic stem cell therapy using low intensity conditioning for high-risk hematological malignancies. Glucksberg staging was used for organ grading of GVHD. Clinical GVHD was assessed as follows: Grade 0: No stage 1-4 of any organ Grade 1: Stage 1-2 rash and no liver or gut involvement Grade 2: Stage 3 rash, or Stage 1 liver involvement, or Stage 1 GI Grade 3: Stage 0-3 skin with Stage 2-3 liver, or Stage 2-4 GI Grade 4: Stage 4 skin rash, or Stage 4 liver involvement

PRIMARY outcome

Timeframe: 100 days

Population: 54 patients were enrolled however 9 patients did not receive planned donor lymphocyte infusion. 45 patients were analyzed.

The primary objective of this study was to establish the rate of acute GVHD following prophylactic cellular immunotherapy after allogeneic hematopoietic stem cell therapy using low intensity conditioning for high-risk hematological malignancies. Glucksberg staging was used for organ grading of GVHD. Clinical GVHD was assessed as follows: Grade 0: No stage 1-4 of any organ Grade 1: Stage 1-2 rash and no liver or gut involvement Grade 2: Stage 3 rash, or Stage 1 liver involvement, or Stage 1 GI Grade 3: Stage 0-3 skin with Stage 2-3 liver, or Stage 2-4 GI Grade 4: Stage 4 skin rash, or Stage 4 liver involvement

Percentage of Participants With Acute Graft Versus Host Disease (GVHD) Grades 2-4
73 percentage of participants

PRIMARY outcome

Timeframe: two years

Population: 54 patients were enrolled however 9 patients did not receive planned donor lymphocyte infusion. 45 patients were analyzed.

The second primary objective was to determine the percentage of participants with progression free survival following prophylactic cellular immunotherapy after allogeneic hematopoietic stem cell therapy using low intensity conditioning for high-risk hematological malignancies. We define disease progression as disease recurrence within 180 days of transplant.
