Подробное описание

The goal of this clinical trial is to evaluate the safety, tolerability and efficacy of human umbilical cord mesenchymal stem cell injection (HS\_SW01 cells injection) in patients with Primary Ovarian Insufficiency (POI).

Participants will be required to sign the informed consent form and will only be assigned to the study and enrolled after undergoing a series of tests and meeting the inclusion and exclusion criteria of the protocol.

This trial consists of a Phase I dose-escalation stage and a Phase II dose-expansion stage. Phase I is a randomized, double-blind, placebo-controlled design in which all participants receive background therapy plus a single intravenous infusion of HS\_SW01 cells injection (1.0×10\^6 cells/kg, 2.0×10\^6 cells/kg, 3.0×10\^6 cells/kg) or placebo, with 4-7 participants per dose group. A "3+3" dose-escalation design is used to evaluate safety, tolerability, pharmacokinetics, and immunogenicity across the three dose groups. In Phase II, the optimal biological dose (OBD) identified from the Phase I escalation study will serve as the recommended Phase II dose (RP2D) to preliminarily assess efficacy while continuing safety monitoring, providing a basis for subsequent clinical trials.

Eligible participants are patients with POI aged ≥18 to \<40 years who meet all inclusion criteria and none of the exclusion criteria.
