Safety Study of Bone Marrow Derived Stem Cells on Patients With Cutaneous Photoaging

Stemedica Cell Technologies, Inc.29 enrolled

Overview

The purpose of this study is to determine whether a one-time injection of allogeneic mesenchymal bone marrow cells is safe and beneficial in the treatment of photodamage on the face.

Mesenchymal stem cells (MSCs) have been isolated from a number of sources, including bone marrow, adipose tissue, and peripheral blood. The MSCs manufactured for this study are a subset of non-hematopoietic stem cells derived from the bone marrow of healthy, adult donors. These cells have the ability to migrate to areas of injury in the body and can differentiate into multiple cell types, including cutaneous cells. In addition to contributing directly to repair of the skin by replacing damaged cells, MSCs also stimulate the body's own cells to regenerate. Though an increasing number of patients are seeking remedies for photoaged skin, current treatments, ranging from topical medications to laser peels, are not ideal methods for addressing the medical need. Because MSCs have been shown in clinical and non-clinical applications to be useful in wound healing, it is also possible that the cells will have a similar effect in skin rejuvenation. In the present study, we will determine the efficacy and safety of intravenously delivered MSCs in otherwise healthy patients with significant cutaneous photodamage.

Interventions

Allogeneic Mesenchymal Bone Marrow CellsBIOLOGICAL

Subjects in Part 1, Cohorts 1-3 will receive a 1550 nm Fraxel laser (6-8 mJ, Level 2) treatment on the face followed by a single intravenous infusion of 0.5, 1.0, or 1.5 million mesenchymal cells per kg of body weight, not to exceed 150 million cells. Subjects in Part 2 will receive a 1550 Fraxel laser (6-8 mJ, Level 2) treatment on the face followed by a single intravenous infusion of mesenchymal cells at the Maximum Tolerated Dose, as determined by the safety results of Part 1. The dose in Part 2 is 1.5 million cells per kg, not to exceed a total of 150 million cells.

Outcomes

Primary Outcomes

MSC Safety and Tolerability

The primary endpoint will be the safety and tolerability of IV administration of allogeneic mesenchymal bone marrow cells (aMBMC) during the twelve month study period as determined by the incidence and severity of adverse events, clinically significant changes on clinical laboratory tests, vital signs, physical and cutaneous examinations, 12 lead ECGs and CT scans of the chest (without contrast)

Time frame: 1 year

Secondary Outcomes

MSC Efficacy

* VISIA-CR 2D photography * PRIMOS 3D images of face and neck * VECTRA 3D photography * Punch biopsy from the lateral canthal area to examine changes in decorin, fibrillin, elastin, MMPI, and procollagen-1 * Subject self-assessment * Independent evaluator assessment * Principal investigator assessment * Changes in RNA sequencing (from blood specimens) * Changes in MMP-1, Ang-2, VEGF and FGF (from blood specimens)

Time frame: 12 months
