Safety Study of Intravenous MiraMSC in Older Adults With Mild to Moderate Frailty Syndrome

Официальное название

A Phase I, Open-Label Study to Evaluate the Safety and Tolerability of MiraMSC Administered Intravenously in Elderly Subjects With Mild to Moderate Frailty Syndrome

Обзор

The purpose of this Phase I, open-label study is to evaluate the safety and tolerability of intravenous MiraMSC-FS-001 in older adults with mild to moderate frailty syndrome. MiraMSC-FS-001 is an investigational product consisting of allogeneic umbilical cord-derived mesenchymal stem cells (UCMSCs). Eligible participants will receive intravenous administration of MiraMSC-FS-001.

Подробное описание

Frailty syndrome (FS) is an age-related clinical condition characterized by reduced physiological reserve and increased vulnerability to adverse health outcomes, including falls, hospitalization, disability, and mortality. Despite its growing prevalence in the aging population, effective treatment options for frailty syndrome remain limited.

MiraMSC-FS-001 is an investigational product consisting of allogeneic umbilical cord-derived mesenchymal stem cells (UCMSCs). Preclinical studies have demonstrated the immunomodulatory, anti-inflammatory, and regenerative properties of UCMSCs, supporting their clinical evaluation as a potential treatment for frailty syndrome. In addition, GLP toxicology studies demonstrated a favorable nonclinical safety profile for MiraMSC-FS-001, supporting its further clinical evaluation in humans.

This Phase I, open-label, dose-escalation study will evaluate the safety and tolerability of intravenous MiraMSC-FS-001 in older adults with mild to moderate frailty syndrome. Eligible participants will receive intravenous MiraMSC-FS-001 according to the study protocol and will undergo scheduled safety evaluations throughout the study. The results of this study are expected to provide clinical safety information to support the further development of MiraMSC-FS-001.

Критерии участия

Критерии включения

Subjects will be eligible for enrollment in the study only if they meet ALL the following criteria at time of Screening:

• Subjects aged ≥ 60 through ≤ 85 years old.
• Subjects with clinical diagnosis of mild to moderate Frailty Syndrome as assessed by the Investigator with a Clinical Frailty Scale score between 4 to

6\. 3. Subject will not start any new treatment for this condition during the study.

• The new treatment refers to any clinical study of new investigational therapies or any other stem cell therapies. Subject will be allowed to continue ongoing medications and therapies that are not prohibited treatment as listed in Section 6.4.1 and are deemed necessary by the Investigator for appropriate medical care. Minor modifications or dose adjustments to ongoing frailty- related treatments that were initiated prior to study enrollment and are not prohibited by the protocol may be implemented if deemed necessary by the Investigator for appropriate care; such adjustments will not be considered the initiation of a new treatment. \*\* 4. Subjects with body weight between 40 to 90 kg. 5. Subject is willing to provide written informed consent to participate in the study after reading the informed consent form and the information provided.

Критерии исключения
