We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

480 patients (320 durvalumab, 160 control) will be recruited over 27 months and followed for another 24 months to provide over 85% power if the true hazard ratio for overall survival was 0.70 with 2-sided alpha of 0.05, assuming a median survival of 15 months in the control group, 21.4 months in the experimental group, and 6% use of immunotherapy in the control group after progression. A single interim analysis will be conducted (at least 6 months after the completion of recruitment and 50% of the events are observed) with alpha spending according to the O’Brien-Fleming boundary.

Brief summary
The purpose of this study is to see whether adding durvalumab, a type of immunotherapy, to standard chemotherapy will improve overall survival in patients with malignant pleural mesothelioma (MPM).

Who is it for?
Participants may be eligible to join this study if they are aged 18 years or above, and have had a diagnosis of MPM that cannot be surgically removed.

Study details:
The study involves allocating participants to receive treatment with standard chemotherapy given with durvalumab, or chemotherapy alone. These treatments are allocated by chance. Treatment will be given by infusion until your disease worsens or you experience unmanageable side effects.

Study treatment:
Chemotherapy and durvalumab group (2 out of every 3 study participants):
This group will receive standard chemotherapy for mesothelioma (cisplatin and pemetrexed) every 3 weeks (one cycle) for a maximum of 6 cycles (about 18 weeks) plus the experimental treatment durvalumab every 3 weeks on the same day as the chemotherapy.

After combination treatment has been completed, participants will continue treatment with durvalumab alone every 4 weeks for as long as they are tolerating the treatment well and the mesothelioma is under control.

Chemotherapy alone group (1 out of every 3 study participants):
This group will receive standard chemotherapy for mesothelioma (cisplatin and pemetrexed) every 3 weeks (one cycle) for a maximum of 6 cycles (about 18 weeks).

After treatment has been completed, participants will receive the same care as they would if they were not on a clinical trial.

After stopping treatment, we would like to follow participants up every 2 months for the rest of their life.

Durvalumab is an antibody (a type of human protein) that works by blocking a body substance called Programmed Death-Ligand 1 (PD-L1). Blocking PD-L1 helps the body's immune system attack cancer cells. Research has shown that durvalumab can slow tumour growth and shrink tumours in some people with cancer. Previous studies of combining durvalumab and chemotherapy showed that this combination is active in advanced mesothelioma.

We plan to enrol 480 participants in this study from hospitals and clinics throughout Australia, New Zealand and the United States of America (USA). Durvalumab is not approved in Australia or any other country for the treatment of advanced mesothelioma. Durvalumab is approved for locally advanced lung cancer and advanced bladder cancer in Australia and the USA.

It is hoped this research will demonstrate that durvalumab is safe and effective for the treatment of advanced mesothelioma, and that the results of this study will lead to improved outcomes for future mesothelioma patients.
