Study Arms (2)

Phase 1Surgical rGBM CYNK-001 infusion ( IV and IC) in combination with IL-2

EXPERIMENTAL

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.

Biological: CYNK-001 systemic and Intra cavity administration

Phase IIa Surgical rGBM CYNK-001 at MPD IV and IC

EXPERIMENTAL

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

Biological: CYNK-001 systemic and Intra cavity administration

Interventions

CYNK-001 systemic and Intra cavity administration BIOLOGICAL

CYNK-001 administered intravenously and intracavitarily in combination with subcutaneous recombinant human IL-2 following lymphodepleting chemotherapy. The study was designed to evaluate escalating dose levels of CYNK-001 in Phase 1 and the recommended dose in Phase 2a. The study was withdrawn prior to enrollment and no participants were treated.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Be 18 years or older of age on the day of signing informed consent.
• Have had historical or current histologically confirmed isocitrate dehydrogenase 1(IDH1) wild-type glioblastoma and variants as defined by the World Health Organization
• Patient must have a T1 weighted 3D MRI with Gadolinium enhancement within 14 days prior to lymphodepletion at Day -5
• Patient must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted.
• Radiologically confirmed recurrent glioblastoma at first or second recurrence have contrast enhancing measurable disease with a bidimensional diameter greater than or equal to 10 mm x 10 mm according to RANO and be eligible to undergo tumor resection.
• Patients must be a candidate to undergo non-emergent surgical resection of the primary target lesion.
• Multifocal GBM is permissible in the study if there is contiguous T2FLAIR hyperintensity between enhancing lesions on T1 post gadolinium sequences and if in the opinion of the PI surgical resection of the multifocal disease is achievable.
• NOTE: Multicentric disease with no demonstrated ventricle communication at the time of screening is excluded.
• The patient must either be on no steroids or on a stable dose of dexamethasone or equivalent no greater than \> 2 mg a day for at least 5 days prior to lymphodepletion.
• Karnofsky performance status (KPS) ≥ 60
• Have washout periods for prior therapies defined as at five half-lives or (4 weeks) prior to the administration of lymphodepletion whichever is shorter
• Demonstrate at screening adequate organ function by laboratory values as follows:
• Absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L
• Platelet count ≥ 100 x 10\^9/L (patient needs to have a minimum of 70 x10\^9/L to undergo resection)
• Hemoglobin ≥ 9 g/dL or ≥ 5.6 mmol/L

You may not qualify if:

• Midline shift greater than 0.5 cm or pending herniation.
• Patients who were previously treated with Bevacizumab. The use of Bevacizumab for edema or radiation necrosis treatments may be allowed with prior approval from the medical monitor
• Anticipated Extent of Resection by volumetric analysis is less than 70%
• Patients with greater than two recurrences of GBM are excluded
• Patients with any contraindications to MRIs
• Treatment with other investigational agents, check point inhibitors and prior immunotherapy such as Vaccine therapy, dendritic cells vaccine within 4 weeks prior to lymphodepletion.
• Prior radiation therapy within 12 weeks of screening MRI unless there is unequivocal histological confirmation of tumor progression.
• Patients with known disease in the posterior fossa, gliomatous meningitis, extracranial disease or multicentric enhancing disease. Multicentric disease is defined as discrete sites of contrast enhancing disease without contiguous T2/FLAIR abnormality.
• NOTE: Satellite lesions that are associated with a contiguous area of T2/FLAIR abnormality as the main lesion(s) may be included.
• Patients with concurrent use of tumor treating fields (TTF) or laser interstitial thermal therapy (LITT) is excluded. Prior use of TTF or LITT is allowed prior to signing the ICF
• Patients with current Carmustine wafers. (Patients that agree to remove the Carmustine wafers at the time of tumor resection during the study are allowed in the study)
• Patents who are receiving systemic steroid therapy \> 2 mg of dexamethasone or equivalent total dose per day or any other form of immunosuppressive therapy within 5 days of lymphodepletion.
• Patients that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Patients requiring physiological doses of steroids (i.e., adrenal insufficiency or hypopituitarism) not to exceed equivalent of dexamethasone 2 mg will not be excluded from the study.
• Patients with history of anaphylaxis, angioedema, interstitial pneumonitis, or acute respiratory distress syndrome
• Active autoimmune disease other than controlled connective tissue disorder or those who are not on active therapy.

Model Details: 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.
