Allogeneic Hematopoietic Stem Cell Transplantation Clinical Trial
Official title:
Sitagliptin Efficacy and Safety for Prevention of Acute Graft Versus Host Disease in Patients Receiving Alternative Donor Allogeneic Hematopoietic Stem Cell Transplantation
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: 1. Determine the tolerability and potential toxicity of sitagliptin in patients undergoing allogeneic HSCT. 2. Determine the cumulative incidence of grades II-IV acute GVHD by day +100. 3. To investigate the cumulative incidence of grades III-IV acute GVHD. 4. To investigate the engraftment kinetics of absolute neutrophil count and platelets. 5. To evaluate the incidence of Cytomegalovirus (CMV), Epstein-Barr virus (EBV) and other infections occurring during the 100 days post-transplant. 6. To study non-relapse mortality (NRM) at day +100, and 1 year post-transplant. 7. Determine the overall survival at 1 year post-transplant. 8. Determine the incidence of chronic GVHD. 9. Determine the cumulative incidence of relapse of the primary hematological malignancy.

Agree to use effective contraception Exclusion Criteria: 1. Prior allogeneic hematopoietic stem cell transplant 2. Allergy/intolerance to Sitagliptin 3. There are contraindications for Sitagliptin use. 4. Moderate or severe renal insufficiency 5. Patients with diabetes mellitus requiring insulin secretagogues and/or insulin 6. Human immunodeficiency virus or active hepatitis C virus or active hepatitis B virus infection 7. Active infection that is difficult to control 8. Vital organ function cannot tolerate transplantation 9. Other malignant tumors outside the blood system, except the following diseases: malignant tumors that have been cured for 3 years without active lesions; Adequate treatment of non-melanoma skin cancer without active foci of malignant amygdala and carcinoma in situ 10. There is evidence that may interfere with the study or make patients at risk of serious complications or medical conditions, including but not limited to serious cardiovascular diseases (such as New York heart association class III or IV heart disease over the past six months of myocardial infarction, unstable type of cardiac arrhythmias) or unstable angina and/or severe lung disease (e.g. History of severe obstructive pulmonary disease and symptomatic bronchospasm) 11. Pregnant or lactating women 12. Any life-threatening medical condition or organ system dysfunction considered by the investigator may endanger the patient's safety by interfering with the absorption or metabolism of sitagliptin or putting study results at unnecessary risk |

Primary | Development Grade II-IV Acute GVHD by Day +100 Following Transplantation | Percent of patients and the 95% Confidence interval who have Grade II-IV Acute GVHD by 100 days following transplantation. Only patients who were on the study for at least 100 days post transplantation were included in the analysis. | up to 100 days | |
Secondary | 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 | |
Secondary | 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 | |
Secondary | 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 | |
Secondary | 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 | |
Secondary | 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 | |
Secondary | Number of Unique Patients With Infections by Day +100 | Number of unique patients who had each type of infection (i.e., viral, bacterial, fungal, etc.) during the 100 days post transplant. A patient could have more than one type of infection. | 100 days from transplant | |
Secondary | Percentage of Patients With Non-relapse Mortality (NRM) at +1 Year | Kaplan-Meier methods will be used to conduct a competing risk analysis. Time until non-relapse death will be calculated from transplant until death. Patients who died from 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 non-relapse mortality at day +365 was calculated along with a 95% confidence interval. | 1 year from transplant | |
Secondary | Percentage of Patients Surviving at +1 Year | Duration of time from the start of treatment to time of death due to any causes. Patients who do not die will be censored on their last known alive date. Kaplan-Meier methods will be used and the median and 95% confidence intervals will be calculated. The cumulative incidence percentage of survival at day +365 was calculated along with a 95% confidence interval. | 1 year from transplant | |
Secondary | Percentage of Patients Diagnosed With Chronic GVHD at 1 Year | Patients surviving at least 100 days will be evaluable for chronic GVHD. 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 | |
Secondary | 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 |
