Clinical Trial Summary

The purpose of this phase 1 study is to determine the optimal dose of the immune suppressive drug, cyclophosphamide, following standard allogeneic stem cell transplant in patients aged >/= 70 years with hematologic malignancies.

Description:

The patients will receive a standard dose, or a reduced amount of the immune suppressive drug, cyclophosphamide, that is routinely administered after the transplant procedure. The following procedures will be performed: cardiac MRI scans and/or transthoracic echocardiogram (TTE); laboratory tests, geriatric assessments and tests to measure strength and stability. Participation in the study is expected to last up to one year with follow-up visits occurring on Day +30, Day +100, Day +180 and Day +365 following allogenic stem cell transplant.

Eligibility

Inclusion Criteria:

• Patient age >/= 70 years
• Patient has a related donor who is a human leukocyte antigens (HLA) haploidentical match
• Patient and Donor sign the Informed Consent Form for the study
• Patient meets standard criteria for allogeneic stem cell transplant
• Patient is deemed suitable to receive Flu/TBI 800 conditioning regimen as standard of care transplant

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum grade acute GVHD by day +100 by Modified Keystone Criteria	Evaluate the frequency of grade III/IV acute GVHD using Modified Keystone Criteria	100 days post-transplant
Secondary	Time to neutrophil and platelet engraftment	Days to neutrophil and platelet engraftment since transplant	60 days post-transplant
Secondary	Non-Relapse mortality	Rate of treatment-related mortality	100 days post-transplant
Secondary	Chronic Graft Versus Host Disease (GVHD) at 1 year	Rate and severity of patients with chronic GVHD at day 365 post-transplantation.; Chronic GVHD is when the donated stem cells attack the body after 100 days post-transplant. Chronic GVHD is defined by NIH Consensus Criteria for chronic GVHD.	1-year post-transplant
Secondary	Relapse	Percentage of patients who relapse by year 1	1-year post-transplant
Secondary	Overall Survival (OS)	Overall survival at 1 year	1-year post-transplant
Secondary	Graft Versus Host Disease (GVHD)-free and Relapse Free Survival	Percentage of patients without relapse or GVHD at 1 year	1-year post- transplant
Secondary	Change in cardiac function	Change in cardiac (heart) injury defined by any of an increase in T1 time > 500 ms from pre-transplant imaging, T2 time > 5 ms from pre-transplant imaging, or a decrease in left ventricular ejection fraction > 10% of the original measurement to below 53% from post-transplant imaging.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in active daily living	Change in function over time as determined by Lawton Activities of Daily Living questionnaire.; - Patients will choose either 0 or 1 to rate their level of function with 1 being the highest level of function.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in function	Change in function over time as determined by the Patient-Reported Outcomes Measurement Information System (PROMIS) Cancer Function Brief 3-Dimensional Profile.; - Patients will rate their physical condition and fatigue using an inverse 5-item likert scale where 5 represents the highest level of function or the greatest amount of impact on function.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in pain	Change in pain over time as determined by the Patient-Reported Outcomes Measurement Information System (PROMIS) Cancer Function Brief 3-Dimensional Profile.; - Patients will rate their level of pain using a scale from 0 to 10 with 10 being the highest level of pain.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in physical function	Change in lower limb functioning over time as evaluated by the Short Physical performance Battery. (SPPB).; - Patients will complete a series of tests evaluating balance, speed and standing capabilities. Patients will be rated using a scale of 0 to 12 where a score of less than 10 indicates mobility limitations.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in grip strength	Change in grip strength as measured using the Jamar dynamometer (device used to measure grip)	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in cognitive function	Change in cognitive function over time using the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognition questionnaire.; -Patients will rate their cognitive ability on a scale of 1 to 5 with 5 representing the least amount of difficulty.	From 60 days prior to transplant to 365 days post-transplant
Secondary	Change in mental health	Change in mental health over time using the Patient-Reported Outcomes Measurement Information System (PROMIS) 29 Depression Questionnaire.; - Patients will rate their level of depression on a scale of 1 to 5 with 5 representing the greatest level of depression.	From 60 days prior to transplant to 365 days post-transplant
