This is a single arm open label phase II clinical trial. Adult patients with hematological malignancies undergoing allogeneic HSCT from matched-related or unrelated donor are eligible for the study if they meet the standard criteria defined in the investigator's institutional standard operation procedures (SOPs), meet all inclusion criteria, and do not satisfy any exclusion criteria. Patients will receive reduced-intensity or myeloablative conditioning regimen of fludarabine, busulfan, and rabbit anti-thymocyte globulin (rATG). Patients will receive PTCyBor as GvHD prophylaxis.

Exclusion Criteria

Pregnant or nursing females or women of reproductive capability who are unwilling to completely abstain from heterosexual sex or practice 2 effective methods of contraception from the first dose of bortezomib through 90 days after the last dose. A woman of reproductive capability is one who has not undergone a hysterectomy (removal of the womb), has not had both ovaries removed, or has not been post-menopausal (stopped menstrual periods) for more than 24 months in a row
Male subjects who refuse to practice effective barrier contraception during the entire study treatment period and through a minimum of 90 days after the last dose of study drug, or completely abstain from heterosexual intercourse. This must be done even if they are surgically sterilized (i.e., post-vasectomy)
Inability to provide informed consent
Patient had myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure (see Appendix E), 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
Known allergies to any of the components of the investigational treatment regimen
Serious medical or psychiatric illness likely to interfere with participation in this clinical study
Diagnosed or treated for another malignancy within 3 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma, 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
