简要总结
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.
详细描述
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.

研究组 & 干预措施
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
干预措施: standard chemotherapy (Drug)
durvalumab
Patients on durvalumab will be given at 1500mg fixed dose every 4 weeks for 24 months
干预措施: durvalumab (Drug)
结局指标
主要结局
Progression free survival
时间窗: 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.
次要结局
- Health related Quality of life (HRQOL)(4 years)
- Objective Response Rate(4 years)
- Overall survival(4 years)
- Adverse event profile(4 years)
