Evaluation of the Safety of Cytokine-Induced-Killer Cells During Early Transplant Period of Autologous Hematopoietic Stem Cell Transplant Recipients.

The goal of this clinical study is to evaluate the safety of cytokine-induced-killer (CIK) cells during early transplant period of autologous hematopoietic stem cell transplant. The main questions it aims to answer are:

* What adverse events occur within 2 years following CIK infusion? * Does viral reactivation (CMV, EBV, BKV) occur and lead to infection during the early transplant period of autologous hematopoietic stem cell transplant after CIK infusion?

Patients will:

* Receive a single infusion of CIK at a dose of 1x10^9 to 1x10^10 cells either intravenously or using a central venous catheter within 14±4 days after receiving the autologous hematopoietic stem cell transplantation. * Attend follow-up visits at the clinic for 24 months after the infusion.

Treatment and study plan

CIK cells

Biological

Derived from the patient (autologous) prior to autologous hematopoietic stem cell transplantation and administered intravenously as fresh cells at a dose of 1x10^9 to 1x10^10 cells over 30 minutes.

Primary outcomes

  1. Adverse Event Assessment

    Time frame: From the baseline visit through 24 months after treatment initiation.

    Adverse events, including any unintended signs, symptoms, or newly developed or worsened diseases, occurring after CIK infusion are tracked for 2 years after the treatment initiation.

  2. 2-Year Progression-Free Survival (PFS) Ratio

    Time frame: From the screening visit through 24 months after treatment initiation.

    • Progression-free survival (PFS) time is defined as the period from the date of autologous hematopoietic transplantation to the date of event.
    • An event is defined as disease progression or death due to any cause.
    • The censoring date is defined as the last date on which it was confirmed that no event had occurred. In cases of loss to follow-up, the censoring date is set as the last date on which the patient was confirmed to be alive.

Secondary outcomes

  1. 2-Year Overall Survival (OS) Ratio

    Time frame: From the screening visit through 24 months after treatment initiation.

    • Overall survival (OS) time is defined as the period from the date of autologous hematopoietic transplantation to the date of event.
    • An event is defined as death due to any cause.
    • The censoring date is defined as the last date on which it was confirmed that no event had occurred. In cases of loss to follow-up, the censoring date is set as the last date on which the patient was confirmed to be alive.

  2. Immunological Assessment and Immune Reconstitution

    Time frame: From the screening visit through 24 months after treatment initiation.

    T cell reconstitution before and after the CIK infusion is assessed using flow cytometry and cytokine expression assays.

  3. Viral Reconstitution

    Time frame: From the screening visit through 24 months after treatment initiation.

    CMV, EBV, and BKV reactivation, along with infection-related complications, are assessed to evaluate the safety and efficacy of the CIK cells.
