Safety Study of Preimplantation Factor (PIF-1) to Treat Acute Steroid-Resistant Graft-Versus-Host Disease (GVHD) (PIF1GVHD)

June 10, 2015 updated by: Hadassah Medical Organization

Phase I Clinical Trial to Assess Safety of Synthetic Preimplantation Factor (PIF-1) in Patients With Steroid-Resistant Acute Graft-Versus-Host Disease (GVHD) After Allogeneic Hematopoietic Stem-Cell Transplantation

The primary goal of this study is to determine the safety and tolerability of a novel peptide - preimplantation factor (PIF-1) - in patients who develop acute steroid-resistant graft-versus-host disease (GVHD) after matched bone marrow transplant (BMT).

Following matched BMT, patients will be placed on standard GVHD preventive therapy (cyclosporine); those who do not respond to cyclosporine are placed on a high-dose steroid regimen for 3 days. Patients that do not respond to this standard treatment will be given PIF-1 subcutaneously for 14 days.

Clinical data and samples will be collected, during PIF-1 administration and for an additional three months thereafter, to examine the long-term effect of PIF-1 treatment on the patients' GVHD status.

Detailed Description

Allogeneic BMT is a well-established treatment modality for malignant and non-malignant hematological diseases. Mature donor T cells within the stem-cell graft are the main mediators of the beneficial immune effects, but they are also responsible for the induction of GVHD, which becomes the major cause of morbidity and mortality post-transplant. Acute GVHD occurs within a 100-day period post-transplant and generally is manifested by dermatitis, enteritis, and hepatitis. The treatment of GVHD continues to be a challenge. To eliminate undesirable host-derived hematopoietic elements before BMT, patients are traditionally treated with myeloablative conditioning regimens involving high-dose chemotherapy and total-body irradiation. Standard GVHD prophylaxis and therapy comprise drugs that cause generalized immune suppression and place patients in danger of opportunistic infections and tumor relapse. For acute GVHD prevention, cyclosporine is often used; however, it is frequently necessary to administer long-term high-dose steroids as well.

An acute GVHD patient's lack of response to steroids is associated with poor prognosis. The ideal prophylaxis treatment for BMT patients would be one that prevented the graft from attacking the host, and that modulated the host's immune response so that it would accept the transplant, while maintaining its ability to protect the body against opportunistic hostile agents.

Pregnancy is an immune paradox: it allows maternal (host) acceptance of a semi-allograft (embryo), while it does not cause graft-versus-host or host-versus-graft reactions against the host/mother, or immune suppression. Therefore, the pregnant immunological status is compatible with the desired immune profile in patients undergoing BMT. By replicating the immune profile present in pregnancy in BMT patients, we may be able to reduce the occurrence of GVHD-related morbidity and mortality rates.

Preimplantation factor (PIF-1) is a novel, embryo-secreted peptide whose synthetic version matches the native peptide's properties. PIF-1 appears to play an important role in mediating the maternal response to pregnancy in mammals. In preclinical studies, PIF-1 has been found to be effective in preclinical BMT-GVHD models, without apparent toxicity.

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.

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

10 years to 66 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Experimental: 1
6 steroid-resistant acute GVHD patients, post-matched BMT (serial)
Drug: Preimplantation factor (PIF-1)

The study will include 6 patients and will last for at least six months. The first three patients will receive PIF-1 (0.5 mg/kg/day for 14 days) by subcutaneous injection. The dosage in the next three patients may be increased to 1 mg/kg/day for 14 days.

Patients will be treated serially: each patient will be followed for 2 weeks after cessation of PIF-1 administration before the next patient begins PIF-1 administration.
