Intravenous Administration of RGI-2001 in Patient Undergoing Allogenic Hematopoietic Stem Cell Transplantation (AHSCT)

Trial ID or NCT#

Status

Purpose

The clinical trial is a Phase 1/2a, open-label, multi-center, dose-escalation study to evaluate the safety, tolerability and pharmacokinetic profile of RGI-2001 in patients undergoing AHSCT, with radiation or non-radiation myeloablative preparative treatment. The study will be separated into two parts; a dose escalation phase to assess safety, followed by a large expansion phase to further evaluate the pharmacologic effects of either a Maximum Tolerated Dose, Maximum Feasible Dose or optimal pharmacologically active dose of RGI-2001. The initial dose escalation safety portion of the study (Part 1) will include higher risk patients and limit the unrelated donor transplants. After safety is established in part 1 of the study, the second portion of the study will expand the enrollment criteria and allow transplantation by either related or unrelated donors. This study will endeavor to identify the dose range at which RGI-2001 has an acceptable safety profile, at which biologic activity is observed, and to guide possible dose levels to utilize in later phase studies based on biological activity.

Female patients of childbearing potential must have a negative serum pregnancy test prior to enrollment and must agree to use dual method of contraception for 30 days after study drug administration. Approved methods of contraception include, an IUD with spermicide, a female condom with spermicide, a diaphragm with spermicide, a cervical cap with spermicide, use of a condom with spermicide by sexual partner or a sterile sexual partner. 13. If male, subjects must be sterile or willing to use an approved method of contraception from the time of Informed Consent to 30 days after study drug treatment. Males must be willing to refrain from sperm donation within 30 days after study drug treatment. 14. No clinically significant acute or chronic medical condition that in the opinion of the investigator will interfere with study participation 15. No clinically significant laboratory abnormalities as determined by the Principal Investigator, in consultation with the Sponsor's Medical Monitor 16. No active infection 17. Have signed written informed consent before undergoing any study related procedures and is willing to comply with all study procedures
Exclusion Criteria:
