简要总结
Phase I study to establish the safety and feasibility of both intravenous administration and local delivery of lentiviral transduced huCART-meso cells in patients with histologically confirmed unresectable or metastatic pancreatic adenocarcinoma
详细描述
This is a Phase I study evaluating the safety and feasibility of lentiviral transduced huCART-meso cells in up to 4 cohorts. Lymphodepleting chemotherapy will not be utilized as part of the planned dosing strategy.
• Cohort 1 (N=3-6): will receive a single dose of 1-3x10^7/m^2 lentiviral transduced huCART-meso cells on day 0 via intravenous infusion.
- Enrollment into Cohort 1 will be paused after the 3rd subject is infused to allow for a formal DLT assessment (performed by the Clinical PI and Medical Director) and DSMB review. If 1 DLT/3 subjects occurs in Cohort 1, the Sponsor (with guidance from the DSMB), will determine whether the study will enroll an additional 3 subjects at this dose level to further establish safety via intravenous infusion, or advance to Cohorts 2 and 3 to explore local delivery of huCART-meso cells at the same dose level. If 0 DLT/3 subjects or 1 DLT/6 subjects occurs at any time, the study may advance to Cohorts 2 and 3.
- If 2 DLTs occur at this dose level at any time, enrollment in Cohort 1 will be stopped and the dose will be de-escalated by 10-fold to 1-3x10^6 cells/m^2 (Cohort -1).
- The infusions in Cohort 1 will be staggered by at least 28 days to allow for the assessment of DLTs for cohort progression, expansion, or dose de-escalation.
In the event that 2 DLTs occur among subjects enrolled in Cohort 1, then enrollment in Cohort 1 will be stopped and the dose will be de-escalated by 10-fold to 1-3x10^6 cells/m^2. This de-escalated cohort will be designated Cohort -1.
• Cohort -1 (N=3-6): will receive a single dose of 1-3x10^6 cells/m^2 lentiviral transduced huCART-meso cells on day 0. Up to 6 subjects will be infused in Cohort -1 if ≤ 1 DLT occurs.

- •Patients with the following diagnoses:
- •Cohorts 1 and -1: Histologically confirmed unresectable or metastatic pancreatic adenocarcinoma
- •Cohort 2: Histologically confirmed unresectable or metastatic pancreatic adenocarcinoma; and either cytologically-proven ascites or known peritoneal disease on radiologic imaging.
- •Cohort 3 - 4: Histologically confirmed unresectable or metastatic pancreatic adenocarcinoma with liver metastases as confirmed by pathology or radiographic imaging.
- •INCLUSION CRITERIA HAS BEEN RETIRED
- •Prior treatment requirements:
- •Cohorts 1 - 3: Failure of at least one prior standard of care chemotherapy for advanced stage disease.
- •Cohort 4: At lease stable disease on the first-line standard of care chemotherapy for advanced stage disease.
- •Cohorts 1-3 and -1: Subjects must have measurable disease as defined by RECIST 1.1 criteria.
- •Patients ≥ 18 years of age.
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or
- •Satisfactory organ and bone marrow function as defined by the following:
- •i. Absolute neutrophil count ≥ 1,000/μl ii. Platelets ≥75,000/μl iii. Hemoglobin ≥ 8 g/dL iv. Direct bilirubin ≤ 2.0 mg/dl unless the subject has Gilbert's disease syndrome (≤ 3.0 mg.dl) v. Creatinine ≤ 1.5x the institutional normal upper limit vi. Albumin ≥ 2 vii. Serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤5x the institutional normal upper limit viii. Cardiac ejection fraction of ≥40% as measured by resting echocardiogram, with no clinically significant pericardial effusion.
- •Blood coagulation parameters: PT such that international normalized ratio (INR) is ≤ 1.5 and a PTT ≤ 1.2 time the upper limit of normal unless the patient is therapeutically anti-coagulated for history of cancer-related thrombosis and has stable coagulation parameters.

排除标准
- •EXCLUSION CRITERIA HAS BEEN RETIRED
- •Active invasive cancer other than pancreatic adenocarcinoma. Patients with active non-invasive cancers (such as non-melanoma skin cancer, superficial cervical and bladder cancer, or prostate cancer with PSA level < 1.0) are not excluded.
- •HIV infection
- •Active hepatitis B or hepatitis C infection
- •Active autoimmune disease (including but not limited to: systemic lupus erythematosus, Sjogren's syndrome, rheumatoid arthritis, psoriasis, multiple sclerosis, inflammatory bowel disease, etc.) requiring immunosuppressive therapy within 4 weeks prior to eligibility confirmation by physician-investigator, with the exception of thyroid replacement.
- •Patients with ongoing or active infection.
- •Dependence on systemic steroids or immunosuppressant medications.

This determination will be made by a cardiologist if cardiac issues are suspected.
