First-in Cancer-Type Phase I Study of FT536 for Recurrent WHO Grade 4 Astrocytoma

NCT07560865 · Status: RECRUITING · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 9

Last updated 2026-05-01

No results posted yet for this study

Summary

This is a single center, first-in cancer-type phase I clinical trial of FT536 for adult patients with recurrent WHO Grade 4 astrocytoma, irrespective of IDH-mutational status, for which a standard of care repeat craniotomy for gross tumor resection at time of first or second recurrence is achievable. Per this treatment schema, FT536 will be administered once intratumorally

BIOLOGICAL

FT536

FT536 is an allogeneic natural killer (NK)-cell immunotherapy produced from a clonal master human induced pluripotent stem cell (iPSC) line with the following four engineered elements: a)deletion of the gene encoding CD38 (i.e., CD38 knockout); b) expression of the MICA andMICB (MICA/B) chimeric antigen receptor (CAR); c) high-affinity, non-cleavable CD16 receptor; and d) an interleukin (IL)-15/IL15 receptor alpha fusion protein.

PROCEDURE

Biopsy/ Intratumoral Injection/ Gross Tumor Resection

On Study Day 1, the region of radiographic concern is biopsied to histologically confirm cancer recurrence versus pseudoprogression. If intraoperative pathology is consistent with cancer recurrence, then FT536 will be injected with a total volume of 1 mL infused via a ventricular catheter placed along the biopsy tract. Occurring between Study Day 8-15, the patient will undergo maximum safe surgical resection

DIAGNOSTIC_TEST

Blood/ Cerebrospinal Fluid/ Tumor Pathology

Blood analysis will occur throughout the study to determine the quality of endogenous NK cells and T cells as well as cytokine concentrations. Cerebrospinal fluid sampling will occur at 2-3 time points throughout the study and the fluid will be analyzed for cytokines and immune cells. Compare pre- (from biopsy) versus post- (from resection) injection pathology to determine FT536 motility, replication ability, and impact on the microenvironment as well as malignant astrocytoma cell death plus the persistence of endogenous NK cells
