Description: An Immunotherapy Platform Study in Platinum Resistant High Grade Serous Ovarian Cancer (IPROC)  

Eligibility: Patients (>=18 yrs old, ECOG PS 0-1), life expectancy >= 3 mo., must have platinum resistant high-grade serous carcinoma of ovarian, fallopian tube or peritoneal origin defined as progression within the last 6 mo. of last platinum containing chemo. Histological confirmation of original primary tumour. Measurable disease per RECIST 1.1. No limit on prior regimens for platinum sensitive disease but may not have received more than 1 cytotoxic chemotherapy regimen for platinum-resistant disease. Prior treatment with immune checkpoint inhibitors is allowed provided it was not discontinued due to severe/recurrent severe toxicity. May have received non-cytotoxic therapies excluding the agents targeted by the planned substudy. Consent to pre/on treatment tumour biopsies. No uncontrolled/serious illnesses or medical conditions which would not permit the patient to be managed per protocol. No central nervous system metastases. No prior autoimmune or inflammatory disorders within the past 3 yrs. 

Objective: Primary: identify based on objective response rate (ORR) (complete and partial response) using RECIST 1.1, promising immunotherapy combinations for the treatment of high grade serious ovarian cancer for later validation in clinical trials. Secondary: evaluate ORR using iRECIST, determine progression free survival and overall survival of immunotherapy regimens (RECIST 1.1 and iRECIST), examine safety and tolerability of each regimen. Tertiary: explore utility of CA125 as a surrogate of response in patients receiving immunotherapies, identify potential predictive biomarkers/markers of response, generate biomarker and clinical data to identify new immunotherapy strategies/combinations for subsequent evaluation. 

Participation: Limited to invited centres 

Lay Description: The purpose of the pre-study screening is to test for biomarkers. This testing will be done on a sample of tissue removed from a previous surgery or biopsy. If a previous tissue sample is not available, a fresh tissue biopsy is required. Each substudy will be looking at what effects a new drug or drugs has on patients and their ovarian cancer and as well as side effects of treatment. The purpose of each substudy is to see if the biomarkers that were identified the screening sample can help predict which patients are most likely to be helped by that drug or drugs and to see how the cancer cells respond to treatment.
