About this study

Official title: A Phase I/Ⅱ Clinical Trial for HS_SW01 Cells Injection in the Treatment of Primary Ovarian Insufficiency

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The incidence of DLT

    Incidence of dose-limiting toxicities (DLTs) within 28 days following study drug administration.

    Measured: Within 28 Days

Secondary outcomes (7)
  1. Changes of the Anti-Müllerian hormone (AMH) serum level from baseline.

    Evaluate the AMH serum level by blood sampling at baseline and at Week 4, Week 12 and Week 24 after administration to assess changes of the Anti-Müllerian hormone (AMH) serum level from baseline.

    Measured: Baseline, Week 4, Week 12, Week 24

  2. Changes of the Follicle Stimulating Hormone (FSH) serum level from baseline.

    Evaluate the FSH serum level by blood sampling at baseline and at Week 4, Week 12 and Week 24 after administration to assess changes of the Follicle Stimulating Hormone (FSH) serum level from baseline.

    Measured: Baseline, Week 4, Week 12, Week 24

  3. Changes of Luteinizing Hormone (LH) serum level from baseline.

    Evaluate the LH serum level by blood sampling at baseline and at Week 4, Week 12 and Week 24 after administration to assess changes of Luteinizing Hormone (LH) serum level from baseline.

    Measured: Baseline, Week 4, Week 12, Week 24

  4. Changes of the Estradiol (E2) serum level from baseline.

    Evaluate the E2 serum level by blood sampling at baseline and at Week 4, Week 12 and Week 24 after administration to assess changes of the Estradiol (E2) serum level from baseline.

    Measured: Baseline, Week 4, Week 12, Week 24

  5. Changes of the Antral Follicle Counting (AFC) from baseline.

    Evaluate the Antral Follicle Counting (AFC) by sonography at baseline and at Week 4, Week 12 and Week 24 after administration to assess Changes of the Antral Follicle Counting (AFC) from baseline .

    Measured: Baseline, Week 4, Week 12, Week 24

  6. Changes of the Ovarian Volume (OV) from baseline.

    Evaluate the Ovarian Volume (OV) by sonography at baseline and at Week 4, Week 12 and Week 24 after administration to assess Changes of the Ovarian Volume (OV) from baseline.

    Measured: Baseline, Week 4, Week 12, Week 24

  7. Changes of the menstrual function indicators from baseline.

    Menstrual function indicators will be recorded via patient diaries or visit questionnaires to evaluate the recovery of menstruation following treatment. The form includes the date of menstrual onset, duration of menstruation (in days), menstrual regularity (regular/irregular; regular defined as cycle fluctuation ≤7 days), and associated symptoms (dysmenorrhea/other, with descriptive notes).Menstrual blood loss will be assessed using the Pictorial Blood Loss Assessment Chart (PBAC), which records, for each menstrual cycle, the type and number of sanitary products used daily, the frequency of clots passed into the toilet, and the total menstrual blood loss (in mL).

    Menstrual function recovery is defined as meeting all of the following criteria:

    (1)At least two consecutive cycles of menstrual bleeding after treatment discontinuation;(2)Cycle length restored to 21-35 days;(3)Menstrual blood volume returned to pre-illness levels compared with the subject's own baseline.

    Measured: Up to Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing HS_SW01 cells injection in people with Primary Ovarian Insufficiency (Poi), run by Shenzhen Huishan Biotechnology Co., Ltd..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 27 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of DLT (time frame: Within 28 Days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2026.
