Maraviroc in Patients Undergoing Non-Myeloablative Allogeneic Stem-Cell Transplantation

April 25, 2022 updated by: Abramson Cancer Center of the University of Pennsylvania

Safety and Efficacy of Maraviroc, a CCR5-inhibitor in Prophylaxis of Graft-Versus-Host Disease in Patients Undergoing Non-Myeloablative Allogeneic Stem-Cell Transplantation

This study investigates the effectiveness and safety of Maraviroc (an oral medication given twice daily given in addition to the standard GVHD prophylaxis) in preventing Graft versus Host Disease (GVHD) in patients undergoing non-myeloablative allogeneic stem-cell transplantation (SCT). Subjects will receive Maraviroc bid (in addition to standard GVHD prophylaxis) beginning after the last dose of the chemotherapy conditioning regimen until day 30 after stem-cell infusion.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

  • Phase 1

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety of Maraviroc
Time Frame: 1 year
number of Adverse Events following exposure to Maraviroc
1 year
Efficacy of Maraviroc
Time Frame: 8 weeks

Efficacy is measured by number of participants progressing to acute GVHD. If acute GVHD is noted in a participant following exposure to study drug, then efficacy was not achieved.

If no GVHD was noted following exposure, then efficacy was achieved in that participant
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetic Profile of Maraviroc in Patients Undergoing Nonmyeloablative Allogeneic SCT
Time Frame: pre-dose, 1,2,3,4,6,12 hours post-dose
Plasma maraviroc levels were measured in the blood with a target level of 100 ng per milliliter. Blood was drawn on Day 0 and Day 10-12 at pre-dose, 1, 2, 3, 4, 6, and 12 hours post-dose. Data was analyzed looking at the number of patients to achieve the target of 100 ng per milliliter at any time point.
pre-dose, 1,2,3,4,6,12 hours post-dose
Number of Patients Treated With Maraviroc During SCT That Develop Chronic GVHD
Time Frame: 1 year
count of how many patients treated with Maraviroc during SCT go on to develop chronic GVHD in 1 year
1 year
Rate of Early Mortality After Transplant
Time Frame: 1 year
Number of participants who died without relapse within 1 year of SCT
1 year
Number of Participants Who Relapsed During Study Period
Time Frame: 1 year and 11 months
Number of participants who received Maraviroc during SCT who relapsed within 1 year and 11 months. This was based on a diagnosis made by their physician that their primary cancer had returned.
