Study Description

Brief Summary

This study evaluates the safety and effectiveness of two different doses of umbilical cord derived, ex-vivo cultured and expanded Wharton's jelly mesenchymal stem cells (MSCTC-0010) in the treatment of acute Graft versus Host Disease (aGVHD). The first 5 participants enrolled in the study will receive a lower dose of MSCTC-0010. If none of the first 5 participants have treatment-related serious adverse events (TRSAEs) for 42 days, then the next 5 participants will receive a slightly higher dose of MSCTC-0010.

Detailed Description

The curative potential of Allogeneic hematopoietic stem cell transplantation (allo-HCT), when applied as a therapy in the management of hematologic malignancies, specifically, derives from an immunologically driven, graft-versus-tumor effect mediated principally by donor T-cells, and is associated with a lesser risk for relapse when compared to high dose chemo-radio therapy and autologous HCT. Donor derived T-cells are also responsible for mediating the occurrence of GVHD, a common transplant-related complication, affecting a significant percentage of patients undergoing allo-HCT leading to the destruction of host tissues. The standard initial treatment for both acute and chronic GVHD is steroid-based therapy. Unfortunately, many of these patients will become resistant to steroid therapy and will subsequently be treated with second-line immunosuppressive agents. De novo high-risk aGVHD and steroid-refractory aGVHD portends a very poor prognosis; second-line agents frequently prove ineffective, and as a result, survival is < 10% at 5 years. Therefore, alternative therapies are needed to treat aGVHD following allo-HCT, particularly in the setting of de novo high-risk acute or steroid-resistant disease.

Due to the large numbers of Mesenchymal stem cells (MSC) that can be obtained from the umbilical cord, the availability of this tissue, their higher growth rates and expansion capacity, and their immune properties, including: (1) low immunogenicity and lack of stimulation of allogeneic T-lymphocyte proliferation, (2) suppression of the proliferation of activated T-lymphocytes, (3) increased production of regulatory T-cells, and (4) a shift in the immune response towards tolerance, Wharton's jelly mesenchymal stem cells (WJMSC) may be a preferred option for MSC.

The rationale for cell dosing in this protocol is based on published data from Kebriaei, et al. Dosing at 2 × 10^{6 MSC/kg body weight produced a complete response in 87.5% of the
treated patients. Dosing at a level 4 times higher (8 × 10}6 MSC/kg body weight) produced no improvement in complete response results. However, the higher dose produced some partial response and no patient failed to respond to therapy. Therefore, the Phase I study for MSCTC-0010 is designed to increase the dose of WJMSC from 2 × 10^{6 MSC to 10 × 10}6 MSC/kg body weight, assuming no dose-limiting toxicity (DLT) is observed at the lower dose.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: MSCTC-0010 Dose Escalation Cohort 1: First 5 participants will receive a lower dose of cord-blood derived Wharton's jelly mesenchymal stem cells (MSCTC-0010) and they will be observed for 42 days after the dose for treatment-related serious adverse events (TRSAE) and response. Cohort 2: Second 5 participants will receive an increased dose of MSCTC-0010 and will be observed for 42 days after the dose for TRSAE and response.	Biological: MSCTC-0010 Dose Escalation Cohort 1: 2.0 × 106 cells per kilogram (cells/kg) body weight, given on day 0 and on day 7 in Participants having de novo High Risk Acute or Steroid Refractory Acute Graft Versus Host Disease (HR/SR aGvHD) Cohort 2: 10 × 106 cells/kg of body weight, given on day 0 and on day 7 in Participants having de novo HR/SR aGvHD Other Names: MSCTC-0010

Outcome Measures

Primary Outcome Measures

proportion of participants who have a TRSAE after infusion of MSCTC 0010 [45 days]
TRSAE is defined as a serious adverse event (SAE) that has a "probable" or "definite" relation to the MSCTC-0010 infusion. This study will use the descriptions and grading scales from Common Terminology Criteria for Adverse Events version 4.03 (CTCAE v4.03) for hematologic and non-hematologic toxicities.

Secondary Outcome Measures

Proportion of participants who achieve a complete response (CR) of aGVHD by study day 42 [42 days]
Complete response is defined as a complete resolution of GVHD.
Proportion of participants with improvement of GVHD in 1 or more organs involved with GVHD by day 42 [42 days]
GVHD will be graded by organ (skin, liver, and gastrointestinal [GI])
Occurrence of addition of escalated immunosuppressive therapy by day 90 [90 days]
Starting at the day 14 evaluation, if the acute GVHD continues to be unresponsive or worsens, additional agents or changes in immunosuppresive therapy will be at discretion of the Investigator per institutional standards.
Occurrence of Formation of ectopic tissue foci at day 90 [90 days]
Defined as ectopic tissue formation of greater than 1.0 centimeter (cm) evaluated by comparison CT scan from screening to day 90.
