Ovarian Cancer Clinical Trial
huCART-meso + VCN-01 in Pancreatic and Ovarian Cancer
This is a Phase I study evaluating the safety and feasibility of lentiviral transduced huCART-meso cells when given in combination with VCN-01 in a 3+3 dose (de)escalation design.
This is a Phase I study evaluating the safety and feasibility of lentiviral transduced huCART-meso cells when given in combination with VCN-01 in a 3+3 dose (de)escalation design as follows:
Cohort 1 (N = 3-6): will receive VCN-01 as a single IV infusion of 3.3x1012 vp on Day 0, followed by a single dose of 5x107 huCART-meso cells on Day 14 via IV infusion. This cohort will be evaluated as follows:
If 1 DLT/3 subjects occurs, Cohort 1 will be expanded to enroll an additional 3 evaluable subjects.
If 0 DLT/3 subjects or 1 DLT/6 subjects, the study will advance to Cohort 2.
Cohort 2 (N = 3-6): will receive VCN-01 as a single IV infusion of 1x1013 vp on Day 0 followed by a single dose of 5x107 cells huCART-meso cells on Day 14 via IV infusion. This cohort will be evaluated as follows:
If 0 DLT/3 subjects or 1 DLT/3 subjects occurs, Cohort 2 will be expanded to enroll an additional 3 evaluable subjects. If 0 DLT/6 subjects or 1 DLT/6 subjects occurs, this dose combination will be identified as the recommended phase 2 dose (RP2D).
If 2 DLTs occur at any time, enrollment in this Cohort will be stopped. If less than 6 subjects were infused in Cohort 1 prior to Cohort 2 escalation, additional subjects will be enrolled in Cohort 1to reach a minimum of 6 evaluable subjects.
In the event that 2 DLTs occur in Cohort 1, then enrollment in Cohort 1 will be stopped and Cohort -1 will be opened for evaluation. Cohort -1 will evaluate a different sequence of administration for these two investigational products at the same dose level used in Cohort 1.
â€¢ Cohort -1 (N = up to 6): will receive a single dose of 5x107 huCART-meso cells via IV infusions on Day 0 followed by VCN-01 as a single infusion of 3.3x1012 vp on Day 10. Up to 6 subjects will be infused in Cohort -1 unless > 1 DLTs are observed at any time.
The Day 0 infusions of the first two subjects in each cohort will be staggered by at least 42 days from the prior subject's 1st infusion (huCART-meso or VCN-01; depending on the cohort assignment), to allow for the assessment of DLTs and a formal decision regarding cohort progression, expansion, or de-escalation. Subsequent subject infusions within that cohort will be staggered by at least 14 days from the preceding subject's second infusion. Formal DLT assessments will be performed by the Clinical PI and Sponsor Medical Director in accordance with the definition provided in the protocol.
Patients with one of the following diagnoses:
Histologically confirmed unresectable or metastatic pancreatic adenocarcinoma; OR

Adequate organ and bone marrow function defined as:
Hemoglobin â‰¥ 9 g/dL
Platelets â‰¥ 75,000/Âµl
PT/INR and PTT â‰¤ 1.5 x ULN
Bilirubin â‰¤ 2.0 x ULN
Creatinine â‰¤ 1.5 x ULN
ALT/AST â‰¤ 5 x ULN (subjects with liver metastases) or ALT/AST â‰¤ 2.5 x ULN (subjects without liver metastases)

Patients with known CNS metastases
Active invasive cancer other than the one of the two cancers targeted by this study. Patients with active non-invasive cancers (such as non-melanoma skin cancer, superficial cervical and bladder and prostate cancer with PSA level < 1.0) are not excluded.
Active hepatitis B or hepatitis C infection.
Chronic hepatitis C with a FibroScan score equivalent to fibrosis stage 2 (F2) or greater.
Patients with known cirrhosis.
Patients with ongoing or active infection.
Patients with a known history of Li Fraumeni syndrome or retinoblastoma protein pathway germinal deficiency.
Active autoimmune disease requiring systemic immunosuppressive treatment equivalent to â‰¥ 10 mg of prednisone. Patients with autoimmune neurologic diseases (such as MS) will be excluded.
Planned concurrent treatment with systemic high dose corticosteroids. Patients may be on a stable low dose of steroids (â‰¤ 10mg equivalent of prednisone). Use of inhaled steroids is allowable.
Patients requiring supplemental oxygen therapy.
History of allergy or hypersensitivity to study product excipients (human serum albumin, DMSO, and Dextran 40).
Any clinically significant pericardial effusion, Class II-IV cardiovascular disability according to the New York Heart Association Classification (see Appendix 4) or other cardiovascular condition that would preclude assessment of mesothelin induced pericarditis or that may worsen as a result of toxicities expected for this study. This determination will be made by a cardiologist if cardiac issues are suspected.
Pregnant or breastfeeding women.
Treatment with a PD-1 or PD-L1 inhibitor, including but not limited to nivolumab, pembrolizumab, atezolizumab, and/or durvalumab, within 2 months prior to eligibility confirmation by a physician-investigator.
Patients with significant lung disease as follows:
Patients with radiographic evidence of greater than lobar lymphangitic pulmonary involvement, greater than lobar bronchial wall thickening suggestive of peribronchial lymphatic disease extension, and/or evidence of extensive bilateral parenchymal metastatic burden.
Patients with radiographic and/or clinical evidence of active radiation pneumonitis.
Patients with radiographic evidence of underlying interstitial lung disease, including evidence of unresolved drug toxicity from any agent (e.g. chemotherapy, targeted agents, amiodarone, nitrofurantoin, etc.)
