NCT00448357 · STUDY IN CONTEXT
Allogeneic Hematopoietic Cell Transplantation for Patients With Busulfex-based Regimen
Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

Linked outcomes
Relapse is defined as new or increased sites of disease or positive one marrow after a complete response (CR). The RFS was calculated as the percentage of patients who were alive and without relapse at 3 years
Dose limiting toxicity will be defined as any irreversible grade 3 or any grade 4 non-hematologic toxicity that is related to busulfan infusion and not graft vs host disease or late infection after recovery from the initial period of myelosuppression. The maximum tolerated dose (MTD) is defined as the dose with probability of dose limiting toxicity (DLT) of 0.25. The dose of continuous infusion IV busulfan based on blood levels derived from a test dose in conjunction with fludarabine and alemtuzumab plus tacrolimus for GVHD prophylaxis.
Test doses of busulfan were administered and plasma levels were measured to determine a targeted AUC dosing estimate. The capacity is reported as the precision with which these test dose goals predicted the actual 90-hour mean AUC levels.Dose targeting precision was estimated by root mean squared error.
GVHD can be mild, moderate or severe depending on the differences in tissue type between patient and donor. GVHD can be acute or chronic. Its symptoms can include: * Rashes, which include burning and redness, that erupt on the palms or soles and may spread to the trunk and eventually to the entire body * Blistering, causing the exposed skin surface to flake off in severe cases * Nausea, vomiting, abdominal cramps, diarrhea and loss of appetite, which can indicate that the gastrointestinal (digestive) tract is affected * Jaundice, or a yellowing of the skin, which can indicate liver damage * Excessive dryness of the mouth and throat, leading to ulcers * Dryness of the lungs, vagina and other surfaces
Deoxyribonucleic acid (DNA) chimerism is a measure identifying the genetic profiles of the transplant recipient and of the donor and then evaluating the extent of mixture in the recipient's blood, bone marrow, or other tissue.
