A Multicenter Phase I Study Evaluating the Addition of Bortezomib to an Established Acute Graft Versus Host Disease Prophylaxis Regimen in Pediatric Allogeneic Hematopoietic Stem Cell Transplant Patients

Exclusion Criteria

• •• Patient has greater than 1.5 times upper limit normal (ULN) Total Bilirubin
• •* Patient has greater than or equal to Grade 2 peripheral neuropathy
• •* Patient had myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at screening must be documented by the investigator as not medically relevant.
• •* Patient has hypersensitivity to bortezomib, boron, or mannitol.
• •* Female subject is pregnant or lactating. Confirmation that the subject is not pregnant must be established by a negative serum beta-human chorionic gonadotropin (beta hCG) pregnancy test result obtained during screening. Pregnancy testing is not required for postmenopausal or surgically sterilized women.
• •* Female patients who are lactating or have a positive serum pregnancy test during the screening period, or a positive urine pregnancy test on Day 1 before first dose of study drug, if applicable.
• •* Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
• •* Diagnosed or treated for another malignancy within 2 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy.
• •* Participation in clinical trials with other investigational agents not included in this trial, within 14 days of the start of this trial and throughout the duration of this trial.
• •* Radiation therapy within 3 weeks before randomization. Enrollment of subjects who require concurrent radiotherapy (which must be localized in its field size) should be deferred until the radiotherapy is completed and 3 weeks have elapsed since the last date of therapy.
• •* Current active infection per physician determination
• •* HIV positive
• •* Previous myeloablative autoHSCT or alloHSCT in previous 12 months
• •* ALT and AST greater than 5 times ULN for age
• •* Creatinine clearance or glomerular filtration rate (GFR) less than 60 ml/min/1.73
• •* Shortening fraction less than 26% or ejection fraction less than 45%
• •* Diffusing capacity of carbon monoxide (DLCO), volume exhaled at end of first second of forced expiration (FEV1), diffusion capacity less than 50% of predicted (corrected for hemoglobin); if unable to perform lung function tests, oxygen saturation less than 94% on room air
