Phase 1 dose escalation will utilize a 3+3 dose escalation design and will evaluate safety, feasibility, and preliminary efficacy of four cohort dose levels of CYNK-001 administered after a 6M IU subcutaneous dose of rhIL-2 for both IV and IC cycles. Up to 21 patients will be enrolled over 4 dosing cohorts in Phase 1.

To evaluate efficacy and safety of CYNK-001 administrations in recurrent GBM at maximum tolerated dose for IV and IC per Phase 1 outcome. No patients staggering will be implemented in phase 2a. DMC will review the phase 2a entirely

Phase 1 Lymphodepletion Days -5,-4 and -3 Cyclophosphamide 900 mg/m2, Fludarabine 30 mg/m2 and Mesna per SOC

IL 2 at 6M IU subcutaneous administration:

For IV cycle ( cycle1) rhIL2 will be administered on Days 1,3,5,8,9,11 and 15 . On days 1, 8 and 15 rhIL-2 will be administered 1 to 3 hours prior to CYNK-001 infusions For IC cycles rhIL2 will be administered 1 to 3 hours prior to each CYNK-001 IC dose.

CYNK-001 : for IV at 2.4 x10\^9 or 3.6 x10\^9 cells Days 1,8 and 15

Tumor resection will take place 7 to 14 day follow by first IC cycle ( Cycle 2) at 100 Million cells or 200 Million cells

IC cycles 3,4,5 once a week for three weeks , 28 days cycle at100 Million cells or 200 Million cells only for Phase 1 cohort 4 and Phase 2a

CYNK-001 systemic and Intra cavity administration

Adrian Kilcoyne, MD

A Phase 1/2a Open Label Multicenter, Non-Randomized, Trial to Assess the Safety and Efficacy of CYNK-001 in Combination with Recombinant Human Interleukin-2 in Adults with Recurrent Resection Eligible IDH1 wild-type Glioblastoma. For phase I portion, the study objectives to assess the safety and feasibility CYNK-001 in combination with rhIL2 of Intravenous (IV) infusion and Intracavitary (IC) administrations following tumor resection and to establish a maximum tolerated dose (MTD) and a Recommended Phase 2a Dose (RP2D) for IV and IC CYNK-001 administration. For Phase IIa, to evaluate efficacy and safety of CYNK-001 administrations in recurrent GBM as measured by Progression Free Survival at 6 months (PFS6M)

The study will contain two phases for the following objectives •The Phase 1 Dose Escalation will utilize a 3+3 dose escalation design and will evaluate safety, feasibility, and preliminary efficacy of four cohort dose levels of CYNK-001 administered after a 6M IU subcutaneous dose of rhIL-2 for both IV and IC cycles. Up to 21 patients will be enrolled over 4 dosing cohorts in Phase1 and 45 patients enrolled for phase IIa. Cohort 4 will be the safety run for Phase IIa. Cohort 4 in its entirety will be reviewed by the DMC prior to starting Phase 2a portion of this study. Phase 2a will continue to explore efficacy and safety of CYNK-001 in combination with rhIL2 in patients with recurrent resection eligible IDH1 wild-type glioblastoma.
