Evaluation of Circulating T Cells and Tumor Infiltrating Lymphocytes (TILs) During / After Pre-Surgery Chemotherapy in Non-Small Cell Lung Cancer (NSCLC)
This trial is active, not recruiting.
|Condition||non small cell lung cancer|
|Treatments||ipilimumab, paclitaxel, cisplatin, carboplatin|
|Start date||March 2013|
|End date||March 2018|
|Trial size||30 participants|
|Trial identifier||NCT01820754, Pro00038093|
The purpose of this study is to evaluate whether the combination of neoadjuvant chemotherapy (chemotherapy before surgery) plus ipilimumab for lung cancer increases the number of patients with detectable circulating T cells with specificities against tumor associated antigens (TAA) from zero percent (0%) of patients prior to therapy to 20% of patients after neoadjuvant chemotherapy plus ipilimumab.
This is an open label Phase 2 trial. Patients with clinical stage IB (>4 cm), II, (N0-2) non-small cell lung cancer (NSCLC) and no prior therapy for the current diagnosis of lung cancer will be eligible for the study. Subjects will receive 3 cycles of neoadjuvant chemotherapy (paclitaxel + cisplatin/carboplatin). Ipilimumab will be administered during Cycles 2 and 3 of standard chemotherapy and for up to 4 cycles alone after surgery. Subjects will undergo standard clinically indicated surgical resection of their lung cancer as deemed appropriate by their surgeon.
Standard diagnostic and staging work up will be performed including: pathologic/histologic diagnosis of NSCLC, Positron Emission Tomography (PET)/Computed Tomography (CT) scan, brain imaging, and mediastinoscopy. Three cycles of neoadjuvant chemotherapy will be given. Ipilimumab will be added to neoadjuvant chemotherapy for cycles 2 and 3. Standard surgical evaluation and therapy will be performed following completion of neoadjuvant therapy. Two cycles of single agent ipilimumab will be given after surgery (adjuvantly), followed by 2 cycles of maintenance therapy.

Both sexually active males and females of reproductive potential must agree to use a reliable method of birth control, as determined by the patient and their health care team, during the study and for 3 months following the last dose of study drug. If subject uses appropriate contraceptive methods (the use of two forms at the same time) from the time of the initial serum pregnancy test, then the subsequent pregnancy test can be done within 72 hours of receiving study drug administration. If appropriate contraceptive measures are not begun immediately with the first serum pregnancy test, then subsequent serum pregnancy tests must be done within 48 hours prior to the study drug administration - Patients must agree to research blood sampling to participate in study Exclusion Criteria: Patients will be excluded from the study if they meet any of the following criteria: - Have had treatment within the last 30 days with a drug that has not received regulatory (Food and Drug Administration (FDA)) approval for any indication at the time of study entry - Concurrent administration of any other anti-tumor therapy - Inability to comply with protocol or study procedures - Active infection requiring intravenous (IV) antibiotics, antifungal or antiviral agents, that in the opinion of the investigator would compromise the patient's ability to tolerate therapy - Major surgery (other than definitive lung cancer surgery) within two weeks of study or other serious concomitant systemic disorders that, in the opinion of the investigator, would compromise the safety of the patient or compromise the patient's ability to complete the study - Myocardial infarction (MI) having occurred less than 6 months before inclusion, any known uncontrolled arrhythmia, symptomatic angina pectoris, active ischemia, or cardiac failure not controlled by medications - Contraindication to corticosteroids - Unwillingness to stop taking herbal supplements while on study - Female patients who are pregnant or breast-feeding - Autoimmune disease. Patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's Disease, are excluded from this study, as are patients with a history of symptomatic disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [eg, Wegener's Granulomatosis]); motor neuropathy considered of autoimmune origin (e.g. Guillain-Barre Syndrome and Myasthenia Gravis) - Any non-oncology vaccine therapy used for prevention of infectious diseases (for up to 1 month before or after any dose of ipilimumab) - A history of prior treatment with ipilimumab or prior CD137 agonist or CTLA 4 inhibitor or agonist - Prisoners or patients who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
|Official title||Evaluation of Circulating T Cells and Tumor Infiltrating Lymphocytes With Specificities Against Tumor Associated Antigens During and After Neoadjuvant Chemotherapy and Phased Ipilimumab in Non-Small Cell Lung Cancer|
|Principal investigator||Neal Ready, MD|
|Description||The investigators propose studying the cell mediated effects of ipilimumab in combination with chemotherapy in the neoadjuvant setting for NSCLC. The overall immune assessment strategy for the proposed ipilimumab neoadjuvant trial will be based on the hypothesis that 1) T cells with specificities against tumor associated antigens expressed by the patient's progressing NSCLC are present, but functionally impaired, at baseline, and 2) that the immunomodulatory effects of chemotherapy plus ipilimumab will impact the suppressive mechanisms, restoring functional reactivity to important anti-tumor effector cell populations. An important potential biomarker for anti-tumor immune response is the proliferation and stimulation of circulating T cells with specificities against tumor associated antigens (TAA). At baseline few patients with cancer have populations of circulating T cells with specificities against TAA above the detectable level of 0.05% CD8 lymphocytes. The primary endpoint of this clinical trial will be to determine if the addition of ipilimumab to neoadjuvant chemotherapy for non-small cell lung cancer increases the percentage of patients with circulating T cells with specificities against TAA. We will also measure tumor infiltrating lymphocytes in resected tumors. Study Interventions: The investigational agent, ipilimumab, will be added to neoadjuvant chemotherapy for cycles 2 and 3. Standard surgical evaluation and therapy will be performed following completion of neoadjuvant therapy. Two cycles of single agent ipilimumab will be given after surgery (adjuvantly), followed by 2 cycles of maintenance therapy. Neoadjuvant: Cycle 1: Paclitaxel 175 mg/m2 IV over 3 hours followed by cisplatin 75 mg/m2 over 60 minutes or carboplatin AUC (Area Under Curve) 6 (capped at 900 mg)over 30-60 minutes on day 1 (every 21 days x 1 cycle) Cycles 2 and 3: Ipilimumab 10mg/kg IV over 90 minutes, Paclitaxel 175 mg/m2 over 3 hours followed by cisplatin 75 mg/m2 or carboplatin AUC 6 (capped at 900 mg)IV over 30-60 minutes (every 21 days x 2 cycles) Surgery: Standard surgical evaluation will occur at least 21 days after the last dose (Cycle 3) of chemotherapy followed by surgical therapy. Post-surgical Therapy: (Total of 4 doses of ipilimumab will be given post-operatively): Adjuvant: Ipilimumab 10 mg/kg IV every 3 weeks x 2 doses, beginning 4 weeks postoperative (up to 10 weeks if needed for recovery) Maintenance: Ipilimumab 10 mg/kg IV every 12 weeks x 2 doses Correlative Science Measures: Study specific research blood and tissue test(s) will be conducted: Blood Specimens: •Peripheral blood mononuclear cells (PBMC) isolated from freshly drawn anti-coagulated blood will be analyzed for circulating T cells with specificities against tumor-associated antigens (TAA) at 4 time points, namely 1) Baseline prior to treatment, 2) cycle 2, prior to ipilimumab therapy, 3) 21-36 days after completion of cycle 3 chemotherapy prior to surgery, and 4) 3-6 weeks after adjuvant ipilimumab dose #2. Additionally, PBMC from each of the time points will be analyzed for the presence of circulating populations of regulatory T cells, myeloid-derived suppressor cells (MDSC), as well as activated and exhausted T cells. Tissue Specimens: •Tumor infiltrating lymphocytes (TILs) will be isolated from the patient's resected tumor and analyzed for infiltrating T cells with specificities against tumor-associated antigens. Additionally, TIL will be analyzed for the presence of infiltrating populations of regulatory T cells, myeloid-derived suppressor cells (MDSC), as well as activated and exhausted T cells.|
