Primary Objective:
It is hypothesized that the efficacy of Sitagliptin would reduce the incidence of grade II-IV acute Graft Versus Host Disease (GVHD) by day +100 post-transplant in patients undergoing alternative donor (related haploid or unrelated donor ) allogeneic Hematopoietic Stem Cell Transplantation (HSCT) and receiving standard GVHD prophylaxis.
Secondary Objectives
The following descriptive secondary objectives will be studied:
This is a Prospective, Multi-center, Open-label, Randomized, Controlled clinical trial of Sitagliptin for the prevention and safety of aGVHD after Alternative Donor hematopoietic stem cell transplantation.
190 adult patients with hematologic malignancies receiving haploid or unrelated donor sourced HSCT are planned to be enrolled competitively in this study from 5 clinical centers in China. These patients will be randomly assigned to two groups of 95 patients each, which one is experimental group and the other is control group. 95 patients in experimental group will receive Sitagliptin combined with Standard prophylaxis for GVHD. 95 patients in the control group will receive Standard prophylaxis regimen for GVHD of Alternative Donor HSCT.
Control group uses antithymocyte immunoglobulin (ATG)+cyclosporin A (CSA)+MMF+MTX for GVHD prophylaxis with the details as follows: CSA 3mg/kg continuous i.v. drip, start before Day -7, change to p.o. when gastrointestinal function recovers with a dose of 5mg/kg as two divided doses, maintaining CSA within 150-250ng/ml（If CsA cannot be tolerated, tacrolimus may be used as an alternative.）; MTX 15mg/m2,Day +1, 10mg/m2,Days +3, +6, and +11; MMF 0.5g bid, starting from Day -7 to day +30 for one month; ATG 2.5mg/kg/d, Day -4 to Day -1.
Experimental group will take Sitagliptin orally from d-1 to d+14 in addition to Standard Prophylaxis Regimen.
With regard to the content of dose reduction of CSA (including time and reduction rate), it is recommended for patients with hematologic malignancies in standard risk group to start to reduce dose after 3-6 months in the absence of GVHD and reoccurrence. The specific reduction rate can be determined at each site; the patients with GVHD will be managed by routine practice in this site.

| Development Grade II-IV Acute GVHD at Day +100 | Fine-Gray and Cause-specific COX methods will be used to conduct a competing risk analysis. Time until grade II-IV acute GVHD will be calculated from transplant through grade II-IV acute GVHD or death from GVHD. Patients who relapsed or died from causes other than GVHD will be considered a competing risk population and calculated from time of transplant until relapse or death. Otherwise, patients will be censored and calculated from transplant until the last known alive date. The cumulative incidence percentage of grade II-IV acute GVHD at day +100 was calculated along with a 95% confidence interval. |

| 100 days from transplant |
| Percentage of Patients With Grade III-IV Acute GVHD at Day +100 | Fine-Gray and Cause-specific COX methods will be used to conduct a competing risk analysis. Time until grade III-IV acute GVHD will be calculated from transplant until grade III-IV acute GVHD or death from GVHD. Patients who relapsed or died from causes other than GVHD will be considered a competing risk and calculated from time of transplant until relapse or death. Otherwise, patients will be censored and calculated from transplant until the last known alive date. The cumulative incidence percentage of grade II-IV acute GVHD at day +100 was calculated along with a 95% confidence interval. | 100 days from transplant |
| Cumulative incidence of early transplant-related death (TRM) within 100 days after transplantation | Percent of patients and the 95% Confidence interval who died within 100 days after transplantation. | 100 days from transplant |
| Median Time to Engraftment of Neutrophils | Time to neutrophil engraftment will be analyzed by the Kaplan-Meier method. The time to engraftment of neutrophils is defined as the time from day 0 to the date of the first of three consecutive days after transplantation during which the absolute neutrophils count (ANC) is at least 0.5 x109/l. Patients who did not have neutrophil engraftment before death will be censored at the date of death. The median and 95% confidence intervals were calculated. | up to 1 month |
| Median Time to Engraftment of Platelets | Time to platelet engraftment will be analyzed by the Kaplan-Meier method. The time to engraftment of platelets is defined as the time from day 0 to the first of seven consecutive Complete Blood Counts (CBCs) obtained on different days after transplantation during which the platelet count is at least 20 x109/l. The CBCs obtained should be at least seven days after the most recent platelet transfusion. The median and 95% confidence intervals were calculated. | up to 4 months |

Otherwise, patients will be censored and calculated from transplant until the last known alive date. The cumulative incidence percentage of non-relapse mortality at day +365 was calculated along with a 95% confidence interval. | 1 year from transplant |
| Percentage of Patients Surviving at +1 Year | Duration of time from the start of treatment to time of death due to any causes.

The cumulative incidence of chronic GVHD (total, and mild, moderate, severe) will be described using deaths from causes other than chronic GVHD considered as a competing risk. Kaplan-Meier methods will be used to conduct a competing risk analysis. Time until chronic GVHD will be calculated from transplant until chronic GVHD or death from GVHD. Patients who relapsed or died from causes other than GVHD will be considered a competing risk and calculated from time of transplant until relapse or death. Otherwise, patients will be censored and calculated from transplant until the last known alive date. The cumulative incidence percentage at 1 year will calculated along with a 95% confidence interval. | 1 year from transplant |
| Percentage of Patients With Relapse of the Primary Hematological Malignancy at 1 Year | Kaplan-Meier methods will be used to conduct a competing risk analysis. Time until relapse will be calculated from transplant until relapse or death from relapse. Patients who died from causes other than relapse will be considered a competing risk and calculated from time of transplant until death. Otherwise, patients will be censored and calculated from transplant until the last known alive date. The cumulative incidence percentage of relapse at day +365 was calculated along with a 95% confidence interval. | 1 year from transplant |
