Breast Cancer Clinical Trial
A Study of CART-TnMUC1 in Patients With TnMUC1-Positive Advanced Cancers
Multi-center, open-label, first in human Phase 1 study of the safety, tolerability, feasibility, and preliminary efficacy of the administration of genetically modified autologous T cells (CART-TnMUC1 cells) engineered to express a chimeric antigen receptor (CAR) capable of recognizing the tumor antigen, TnMUC1 and activating the T cell (CART- TnMUC1 cells).
The Dose Escalation phase of the study is designed to identify the dose and regimen of CART-TnMUC1 cells that can be safely administered intravenously following the lymphodepletion (LD) regimen to patients with (1) advanced TnMUC1+ solid tumors (triple negative breast cancer, epithelial ovarian cancer, pancreatic cancer, and non-small cell lung cancer) and (2) advanced TnMUC1+ multiple myeloma in a parallel two-arm dose escalation study. The Dose Escalation phase is anticipated to enroll approximately 40 patients.
The Expansion phase of the study is designed to assess the preliminary efficacy of CART-TnMUC1 cells administered intravenously to patients with TnMUC1+ solid tumors. The Expansion phase is anticipated to enroll approximately 72 patients (18 patients per each tumor indication).
Key Inclusion Criteria:
Confirmed diagnosis of metastatic treatment-resistant ovarian cancer (including cancers of the fallopian tube), pancreatic adenocarcinoma, hormone receptor (HR)-negative and HER2-negative (triple negative) breast cancer (TNBC) or non-small cell lung cancer (NSCLC), or relapsed/refractory multiple myeloma
Eastern Cooperative Oncology Group (ECOG) score of 0 or 1
Prior therapies as defined by tumor type:
Multiple myeloma: relapsed or refractory disease previously treated with or intolerant to at least three different lines of therapy that contained at least one of the following drug classes: proteasome inhibitor, an immune modulatory drug, alkylators, CD38 monoclonal antibody and glucocorticoids. Patients must be at least 90 days since autologous stem cell transplant
NSCLC: i.) Patients without driver mutations must have received standard therapy, including both checkpoint inhibition and platinum-based chemotherapy or be intolerant of these standard therapies ii.) Patients with driver mutations must have received or be intolerant to prior targeted therapy directed at the specific identified mutations in addition to the standard chemotherapy classes
Pancreatic adenocarcinoma: disease progression following at least one standard of care systemic chemotherapy for metastatic or unresectable disease or be intolerant of these standard therapies
TNBC: ER and/or PR < or =10%, HER2 negative and experienced disease progression following at least one prior systemic anti-cancer therapy regimen as part of their treatment for management of metastatic breast cancer or be intolerant to these standard therapies
Ovarian: platinum-resistant (progression of disease by either CA-125, clinical or radiographic assessment within 6 months of last platinum-based chemotherapy ) and must have received at least two prior lines of therapy for metastatic ovarian cancer, including at least one prior line of therapy including a platinum-containing regimen or be intolerant of these standard therapies
Evaluable disease as defined by tumor type
TnMUC1+ disease, determined by centrally tested TnMUC1 expression in a prior or archival tumor biopsy
Toxicities from any previous therapy must have recovered to Grade 1 or baseline
Estimated estimated glomerular filtration rate ≥ 60 m/min by Modification of Diet in Renal Disease criteria
Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 2.5 x upper institutional limit of normal with the following exception: Patients with known hepatic metastases, AST or ALT ≤ 3 x upper institutional limit of normal
Serum total bilirubin < 1.5 mg/dL with the following exception: patients with known Gilbert's disease, serum total bilirubin < 3 mg/dL
Serum albumin ≥ 3.0 g/dL (solid tumor patients in Arm 1 and Phase 1a only, not applicable to patients with multiple myeloma)
Left ventricular ejection fraction (LVEF) ≥ 50%. LVEF assessment must have been performed within 6 months of treatment start
Hemoglobin ≥ 8 g/dL
Absolute neutrophil count ≥ 1000/μL
Platelet count ≥ 75,000/μL (for Multiple Myeloma patients with bone marrow plasma cells ≥ 50% of cellularity: ≥ 30,000/μL)
Patients of reproductive potential agree to use approved contraceptive methods per protocol
Key Exclusion Criteria:
Active invasive cancer other than the proposed cancers included in the study
Current treatment with systemic high-dose corticosteroids (defined as a dose greater than the equivalent of prednisone 10 mg/day)
Active autoimmune disease (including connective tissue disease, uveitis, sarcoidosis, inflammatory bowel disease or multiple sclerosis) or have a history of severe autoimmune disease requiring prolonged immunosuppressive therapy (any immunosuppressive therapy should have been stopped within 6 weeks prior to screening visit)
Current human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV) infections
Other active or uncontrolled medical or psychiatric condition that would preclude participation in the opinion of the Sponsor or Principal Investigator
Prior allogeneic stem cell transplant
Active and untreated central nervous system (CNS) malignancy
History of severe infusion reaction to monoclonal antibodies or biological therapies, or to study product excipients that would preclude the patient safely receiving CART-TnMUC1 cells
Active or recent (within the past 6 months prior to apheresis) cardiovascular disease, defined as (1) New York Heart Association (NYHA) Class III or IV heart failure, (2) unstable angina or (3) a history of recent (within 6 months) myocardial infarction or sustained (> 30 second) ventricular tachyarrhythmias, or (4) cerebrovascular accident
Have inadequate venous access for or contraindications for the apheresis procedure
