Outcome Measures

Primary Outcomes (3)

  • Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

    To investigate the safety characteristics, percentages will be calculated and grade will be evaluated.

    From the day that UCMSC-Exo is infused to up to 28 days (short-term safety follow-up) and 1 year (long-term safety follow-up)

  • Dose-limiting toxicities(DLT)

    During the DLT observation period, the subject has an adverse event that is reasonably related to UCMSC-Exo infusion (possibly, likely or definitely related).

    From the day that UCMSC-Exo is infused to up to 14 days

  • Maximum tolerated dose (MTD)

    During the dose-escalation, the highest dose of dose-limiting toxicity for subjects no more than 1/6 in the dose group of at least 6 evaluable subjects of the study drug.

    From the day that UCMSC-Exo is infused to up to 14 days

Secondary Outcomes (13)

  • Time to absolute neutrophil count recovery

    From the start of chemotherapy to up to 42 days

  • Incidence of febrile neutropenia

    From the start of chemotherapy to up to 42 days

  • Duration of febrile neutropenia

    From the start of chemotherapy to up to 42 days

  • Incidence of severe thrombocytopenia

    From the start of chemotherapy to up to 42 days

  • Time to severe thrombocytopenia recovery

    From the start of chemotherapy to up to 42 days

  • +8 more secondary outcomes

Study Arms (1)

UCMSC-Exo intervention

EXPERIMENTAL

UCMSC-Exo will be preset with 3 escalation dose levels in single time infusion.

Biological: umbilical cord derived mesenchymal stem cells exosomes (UCMSC-Exo)

Interventions

UCMSC-Exo will be infused intravenously.

  • Participants who do not receive any type of anti-cancer therapy within 2 weeks before enrollment (radiation therapy, chemotherapy and/or immune therapy, et al.), and treatment-associated toxicities induced by previous therapy has recovered to Grade 1 or below (except for low grade toxicities such as alopecia).
  • For female participants, they should be surgical sterilized or post-menopausal, or agree to utilize a medically recognised method of contraception (such as intrauterine device, condom) during treatment period of the study and within 6 months after the end of treatment period of the study; For male participants, they should be surgical sterilized or agree to utilize a medically recognised method of contraception (such as intrauterine device, condom) during treatment period of the study and within 6 months after the end of treatment period of the study;

You may not qualify if:

  • Secondary acute myeloid leukemia;
  • Myelosuppression induced by conditions other than anti-cancer therapy;
  • Previous radiation therapy performed on sternum or pelvis;
  • Specifically diagnosed and uncontrolled infection at enrollment (Uncontrolled is defined as exhibiting ongoing signs and symptoms of infection without improvement despite anti-infective agents) ;
  • Uncontrolled active bleeding at enrollment;
  • Severe underlying comorbidities affecting survival, including cachexia, severe malnutrition, etc;
  • Estimated survival of at most 48 hours;
  • Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection;
