Phase 1/Phase 2 |
Detailed Description
Treatment on this study includes eight Human Induced Pluripotent Stem Cell derived natural killer cell（ XS005 cell ）infusions over an 16 week period. The study will evaluate the safety, feasibility and maximum tolerated dose (MTD) of XS005 cell using a 3+3 study design . The total study duration will be 2 years.

Outcome Measures
Primary Outcome Measures
- Incidence of Dose-Limiting Toxicities (DLTs) [within 7 days after the the first infusion of XS005.]
DLT is defined as a toxic effect in the subject at any dose, cannot be reasonably attributed to the subject's underlying disease, other conditions, and/or concomitants, that the investigator determines to be related (including definitely, likely, or possibly) to the XS005 cell injection.
- Incidence of Adverse Events (AEs) [4 months]
AE is defined as any adverse medical event within 4 months after the the first infusion of XS005.
- Maximum tolerated dose (MTD) [within 7 days after the the first infusion of XS005.]
MTD is defined as the highest dose level of less than or equal to 2 DLT among the 6 subjects finally determined.
Secondary Outcome Measures
- Progression-free survival (PFS) [From the start of treatment until the time of first disease progression or death , assessed up to 12 months post-treatment]
PFS : defined as the time from the start of treatment until the onset of tumor progression or death from any cause;
Other Outcome Measures
- Number of natural killer (NK ) cells in cerebrospinal fluid(CSF). [Day 2 to day 9 of each treatment cycle（each treatment cycle is 28 days）.]
Changes of NK cells in CSF pre-and post- infusion and at each of the main follow-up time points.
- Changes of cytokines in CSF. [Day 2 to day 9 of each treatment cycle（each treatment cycle is 28 days）.]
Changes of cytokines (such as interleukin-6(IL-6), interferon-γ (IFN-γ) etc.) in CSF pre-and post- infusion and at each of the main follow-up time points.
