May 2, 2023 updated by: Masonic Cancer Center, University of Minnesota

Nivolumab and Oral Cyclophosphamide for Relapsed/Refractory Acute Myeloid Leukemia (AML) and Higher-Risk Myelodysplastic Syndrome (MDS)

This is a phase II trial of nivolumab and low dose cyclophosphamide (CTX) when given in combination to patients with relapsed/refractory acute myeloid leukemia (AML) and higher-risk myelodysplastic syndrome (MDS) who are not eligible for or decline hematopoietic stem cell transplant. It includes a randomized pilot sub-study during stage 1.

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.

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)

No

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
Stage 1: Dosing Schedule of Low-dose Cyclophosphamide
Time Frame: 4 weeks from start of treatment
Number of participants with adverse events
4 weeks from start of treatment
Clinical Benefit and Immunologic Response of the Combination Therapy
Time Frame: 90 days from start of treatment

Overall response rate at 90 days from treatment start. Response is defined as CR + CRi + CRp + PR in AML and CR/PR/hematologic improvement (HI) in MDS.

Complete Remission (CR) - subjects must have bone marrow regenerating normal hematopoietic cells and achieve a morphologic leukemia-free state, an ANC > 1 x 109/L and platelet count ≥ 100 x 109/L and normal marrow differential with < 5% blasts, and they will be RBC and platelet transfusion independent (defined as 1 week without RBC transfusion and 1 week without platelet transfusion). There should be no evidence of extramedullary leukemia

Complete Remission with Incomplete Hematologic Recovery (CRi) - subjects must fulfill all the criteria for CR except for incomplete hematological recovery

Complete Remission with Incomplete Platelet Recovery (CRp) - subjects must achieve CR except for incomplete platelet recovery

Partial Remission (PR) - subjects must have ≥50% bone marrow blast reduction or decrease to 5 to 25%
90 days from start of treatment

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
Objective Response Rate (ORR)
Time Frame: 30 days from start of treatment
Incidence of overall response.
30 days from start of treatment
Progression Free Survival (PFS)
Time Frame: 6 months from start of treatment
