Acute Myeloid Leukemia Clinical Trial

Dendritic Cell/AML Fusion Cell Vaccine Following Allogeneic Transplantation in AML Patients

Summary

This research study is studying a cancer vaccine called Dendritic Cell/AML Fusion vaccine (DC/AML vaccine) as a possible treatment for Acute Myelogenous Leukemia (AML).

The interventions involved in this study are:

Dendritic Cell/AML Fusion vaccine (DC/AML vaccine)
Decitabine, a chemotherapy drug

Full Description

This research study is a Phase I clinical trial, which tests the safety of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. This study is investigating the DC/AML vaccine with and without the drug decitabine as a possible treatment for AML in the post-transplant setting.

The FDA (the U.S. Food and Drug Administration) has not approved the DC/AML vaccine as a treatment for any disease.

The FDA has approved decitabine as a treatment option for this disease.

The FDA has not approved the combination of the DC/AML vaccine with decitabine as a treatment option for any disease,

In this research study, the investigators are determining if the DC/AML vaccine can be used safely in subjects with acute leukemia after they have undergone a transplant, and whether the DC/AML vaccine alone is capable of producing immune responses against leukemia. Cancer cells are foreign to the body and have unique markers that distinguish them from normal cells.

These markers can potentially serve as targets for the immune system. An immune response is any reaction by the immune system; a complex system that is responsible for distinguishing us from everything foreign to us, and for protecting us against infections and foreign substances.

The DC/AML vaccine is an investigational agent that tries to help the immune system to recognize and fight against cancer cells. Unlike a standard vaccine that is used to prevent infections, cancer vaccines are being studied to see if they can fight cancers that are already in the body. Laboratory studies have shown that when dendritic cells and tumor cells are brought together, the dendritic cells can stimulate immune responses against the tumor and, in some cases, cause the tumor to shrink.

Decitabine is thought to act as an anti-metabolite. It seems to work by having a toxic effect on the abnormal bone marrow cells. It also appears to affect the DNA in genes that control cell growth. This promotes normal specialization and blood cell growth, so that the body is better able to make red blood cells, white blood cells, and platelets.

Patients must have had a minimum of 5x107 cells cryopreserved.

Patients must be day 25-45 following allogeneic transplantation from either:

Group A: HLA 8/8 or 7/8 matched related donor or HLA 8/8 matched unrelated donor, as determined by antigen or allele level typing at HLA A,B,C, and HLA DRB1.

OR

Group B: Haplo-identical donor

Patients must be ≥ 18 years old
ECOG performance status ≤2 (Appendix A)
Participants must have normal organ and marrow function as defined below:

Creatinine ≤ 2.0 mg/dl
Absolute neutrophil count > 1000

Platelet count > 50,000

The effects of DC/AML fusion cells on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

Resolution of all transplant related grade III-IV toxicity as per CTC criteria 4.0
Complete remission defined by absence of circulating blasts and less than 5% blasts in the bone marrow
Ability to understand and the willingness to sign a written informed consent document.

Eligibility Prior to Initiating Vaccination (Groups A and B)

Assessments to be done between Day 45-75 post-transplant.
At least 2 doses of fusion vaccine were produced
No ongoing grade II-IV acute GVHD
Prednisone requirement of < 20mg a day or steroid equivalent

Participants must have normal organ and marrow function as defined below:

Total bilirubin ≤ 2.0 mg/dL (unless patient has Gilbert's disease)

Creatinine ≤ 2.0 mg/dl
Absolute neutrophil count > 1000
Platelet count > 50,000
No uncontrolled acute infection
No CTCAE grade ≥ 3 non-hematologic toxicity
No serious intercurrent illness such as active acute infection, or significant cardiac disease characterized by clinically significant arrhythmia, active ischemic coronary disease or symptomatic congestive heart failure.
Participants must be in a complete remission

Pre-Treatment Criteria Prior to Decitabine (Group A Cohort 2)

Assessments to be done within 3 days prior to initiation of therapy.
Participants must have normal organ and marrow function as defined below:

Participants may not be receiving any other Non-FDA approved study agents at the start of vaccination
Uncontrolled intercurrent illness including uncontrolled active infection, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia, or psychiatric illness that would limit compliance with study requirements.
