Brief Summary:
The purpose of this study is to find out if treatment with a study drug, durvalumab has beneficial effects in people who have recurrent ovarian clear cell cancer and to determine what effects (both good and bad) it has on them and their cancer.

Condition or disease Intervention/treatment Phase
Ovarian Clear Cell Carcinoma Drug: durvalumab Drug: standard chemotherapy Phase 2

Detailed Description:

The purpose of this study is to find out if treatment with a study drug, durvalumab has beneficial effects in patients who have recurrent ovarian clear cell cancer and to determine what effects (both good and bad) it has on them and their cancer.

In the recurrent ovarian clear cell cancer (OCCC) setting, responses to further lines of chemotherapy are uniformly low. Given the limited benefit observed from chemotherapy treatments, there is now great interest in the development of molecular targeted therapy for the treatment of OCCC, including immunotherapy.

Researchers have found that sometimes the body's own immune system may be able to slow down or control cancer growth. Sometimes though, this natural immune system response stops, and the cancer cells are not killed by the immune system. Research has shown that in some patients, proteins on the surface of cancer cells and immune cells bind together and send signals that stop the immune cells from killing the cancer cells. One such protein is called Programmed Cell Death Ligand 1 or PD-L1 for short. New drugs like durvalumab work to block this signal and to increase the immune response against cancer cells. Durvalumab is an antibody to PDL1 (a protein that binds to PD1 and blocks the anti tumour activity of immune cells), and it is hoped that by blocking the interaction between PDL1 and PD1, the immune cells will once again be able to attack the cancer cells and thus prevent or slow down cancer growth.

This will be the first study to evaluate the efficacy of durvalumab in patients with recurrent ovarian clear cell carcinomas.

Drug Information available for: Durvalumab

Arm Intervention/treatment
Active Comparator: standard chemotherapy
Patients on physician's choice of chemotherapy are allowed to receive any systemic chemotherapy either as a single agent or in combination. However, biologics( including bevacizumab) and oral tyrosine kinase inhibitors will not be allowed for patients on this arm
Drug: standard chemotherapy
chemotherapy treatment will be administered as per local institutional guidelines

Experimental: durvalumab
Patients on durvalumab will be given at 1500mg fixed dose every 4 weeks for 24 months
Drug: durvalumab
Durvalumab will be given at 1500mg fixed dose every 4 weeks for 24 months or until the appearance of significant treatment-related toxicity or disease progression

Primary Outcome Measures :
  1. Progression free survival [ Time Frame: 4 years ]
    Progression free survival (PFS) is defined as the time from the first day of treatment to the first observation of radiological or clinical disease progression or death due to any cause or last follow-up. The progression will be defined by RECIST criteria v1.1 for patients on the chemotherapy arm which includes first instance of more than 20% increase in the sum of diameters or unequivocal progression in non-target disease. The sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) is calculated at baseline and at each tumor assessment.

Secondary Outcome Measures :
  1. Objective Response Rate [ Time Frame: 4 years ]
    Objective response rate (ORR) is defined as the percentage of subjects with a confirmed CR or PR as per RECIST 1.1 criteria. Response will be evaluated every 8 weeks while on treatment.

  2. Overall survival [ Time Frame: 4 years ]
    Overall survival (OS) is measured as time from the first day of treatment to the time of death from any cause.

  3. Health related Quality of life (HRQOL) [ Time Frame: 4 years ]
    HRQOL will be measured using European Organization for Research and Treatment of Cancer Core questionnaire.

  4. Adverse event profile [ Time Frame: 4 years ]
    Adverse event profile of durvalumab in this patient population as measured by CTCAE 4.0 criteria

Layout table for eligibility information
Ages Eligible for Study:   21 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Gender Based Eligibility:   Yes
Gender Eligibility Description:   Only the females are affected by the ovarian clear cell carcinoma (OCCC).

Patient Inclusion Criteria

Patients will be eligible for inclusion in this study if all of the following criteria apply:

  1. Provision of signed, written and dated informed consent prior to any study specific procedure
  2. Female aged 18 years (21 years in Singapore) or older
  3. Have histologically documented diagnosis of ovarian clear cell carcinoma as evidenced by WT1 negativity. For tumors with a mixed histology, at least 70% of the tumor must consist of clear cell carcinoma.
  4. Provision of an archived tumour tissue block (or at least 10 newly cut unstained slides) where such samples exist in a quantity sufficient to allow for analysis
  5. Patients must have had a prior line of platinum-based chemotherap y in the course of their treatment paradigm
  6. A maximum of 4 prior lines of systemic treatment regimens will be allowed and may include chemotherapy and biologics (prior immune checkpoint inhibitor treatment will not be permitted).
  7. Meet RECIST criteria (version 1.1) within 28 days of start of treatment by having measurable disease defined as one or more lesions that can be accurately measured at baseline as ≥ 10mm in the longest diameter (except lymph nodes which must have a short axis of ≥ 15mm with CT or MRI and which is suitable for repeated measurements). Patients must have radiographic evidence of disease progression following most recent line of treatment. Areas of previous radiation may not serve as measurable disease unless there is evidence of progression post radiation.
  8. At time of registration, if the patient has had previous treatment it must have been at least 4 weeks since major surgery or radiation therapy; four weeks from any other previous anti-cancer therapy including biologics. Patients must have recovered from their treatment-related events to ≤1 with the exception of alopecia and neuropathy (≤ 2 sufficient).
