High IL-6 levels correlate with poor prognosis and chemoresistance in ovarian cancer patients. In cases of chemoresistant ovarian cancer, therefore, modulation of the IL-6 pathway, by blocking the IL-6 receptor, may represent a promising strategy to both abolish drug resistance and amplify host immunity in patients with recurrent ovarian cancer. Blockade of the IL-6/IL-6R pathway may enhance immunogenic cell death and restore local normal DC maturation. In addition, the use of interferon-alpha (Peg-Intron) allows the full maturation of DC, thereby enhancing the anti-tumor response.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Histologically proven epithelial ovarian cancer\n* Progression of disease or relapse after previous therapy with platinum\n* Measurable disease (RECIST 1.1) or elevated CA125 \\> 2 times the upper normal limit (UNL) within 3 months and confirmed\n* Age ≥18 years\n* WHO performance status 0-2\n* Adequate bone marrow function: WBC ≥3.0 x 109/l, neutrophils ≥1.5 x 109/l, platelets ≥100 x 109/l\n* Adequate liver function: bilirubin ≤1.5 x UNL range, ALAT and/or ASAT\n\n * 2.5 x UNL (\\<5x UNL in case of liver metastases), Alkaline Phosphatase ≤5 x UNL\n* Adequate renal function: the calculated creatinine clearance should be\n\n * 50 mL/min\n* Survival expectation \\> 3 months\n* Patients must be accessible for treatment and follow-up\n* Written informed consent according to the local Ethics Committee requirements\n\nExclusion Criteria:\n\n* Chemotherapy within past 3 months\n* Previous malignancy within 5 years, with exception of a history of a previous basal cell carcinoma of the skin or pre-invasive carcinoma of the cervix\n* Serious other diseases as recent myocardial infarction, clinical signs of cardiac failure or clinically significant arrhythmias\n* Known hypersensitivity reaction to any of the components of the treatment\n* Pregnancy or lactating\n* Medical or psychological condition which in the opinion of the investigator would not permit the patient to complete the study or sign meaningful informed consent\n* Infection with tuberculosis and hepatitis B or C'}, 'identificationModule': {'nctId': 'NCT01637532', 'acronym': 'PITCH', 'briefTitle': 'Feasibility of the Combination of Chemotherapy (Carbo/Caelyx or Carbo/Doxorubicin) With Tocilizumab (mAb IL-6R) and Peg-Intron in Patients With Recurrent Ovarian Cancer', 'organization': {'class': 'OTHER', 'fullName': 'Leiden University Medical Center'}, 'officialTitle': 'Chemo-Immunotherapy: Observational Trial of Carboplatin-pegylated Liposomal Doxorubicin (PLD) or Doxorubicin Combination Chemotherapy With Tocilizumab, a Humanized Monoclonal Antibody Against the Human Interleukin-6 (IL-6) Receptor, and Pegylated Interferon Alpha (Peg-Intron) for Patients With Recurrent Ovarian Cancer.', 'orgStudyIdInfo': {'id': 'PITCH trial'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'Group 1', 'description': 'Carboplatin/Caelyx', 'interventionNames': ['Drug: Carboplatin and Caelyx or doxorubicin']}, {'type': 'EXPERIMENTAL', 'label': 'Group 2', 'description': 'Carboplatin/Caelyx or doxorubicin plus Tocilizumab', 'interventionNames': ['Drug: tocilizumab and interferon alpha 2-b', 'Drug: Carboplatin and Caelyx or doxorubicin']}, {'type': 'EXPERIMENTAL', 'label': 'Group 3', 'description': 'Carboplatin/Caelyx or doxorubicin plus Tocilizumab plus Peg-Intron', 'interventionNames': ['Drug: tocilizumab and interferon alpha 2-b', 'Drug: Carboplatin and Caelyx or doxorubicin']}], 'interventions': [{'name': 'tocilizumab and interferon alpha 2-b', 'type': 'DRUG', 'description': 'During first three chemotherapy cycles, tocilizumab and/or Peg-Intron are added.\n\nTocilizumab is given in a dose-escalation scheme (1,2,4,8mg/kg n=3) and Peg-Intron is adminstered subcutaneously 1.0ug/kg', 'armGroupLabels': ['Group 2', 'Group 3']}, {'name': 'Carboplatin and Caelyx or doxorubicin', 'type': 'DRUG', 'description': 'Standard chemotherapeutic care given in every arm as standard care.
