This study looked at a drug called rucaparib for people who had solid tumours. It was for people whose cancer had grown into surrounding tissue or spread elsewhere in the body. This is locally advanced or advanced cancer.
are any type of cancer apart from blood cancers such as leukaemia. The trial included women who had cancer of the
, fallopian tube cancer or primary peritoneal cancer. Doctors treat these cancers in the same way. So, when we use the term ovarian cancer in this summary, we are referring to all 3.
This study was open for people to join between 2011 and 2016. Some results were published in 2017 and some in 2018.
The usual treatment for ovarian cancer that has spread is surgery and chemotherapy. Doctors were looking for ways to improve treatment. In this study, they looked at a drug called rucaparib.
Rucaparib is a type of drug known as a PARP inhibitor. PARP is an enzyme that helps damaged cells to repair themselves. Cancer cells with gene changes already have problems repairing themselves. The researchers hoped that by blocking PARP, cancer cells with and
mutations wouldn’t be able to repair themselves and would die.
In this study people had rucaparib as a tablet.
The main aims of this study were to:
The researchers found the best dose of rucaparib for people with solid tumours. They found this dose worked for women with advanced ovarian cancer who had a BRCA gene change in their cancer cells. And the side effects were manageable.
About this study
There were 3 parts to this study:
In part 1 the first few people taking part had a low dose of rucaparib. If they didn’t have any serious side effects, the next few had a higher dose. And so on, until they found the best dose to give. This is called a dose escalation study.
When the study team found this dose then part 2 and part 3 of the study began.
Results
56 people joined part 1 and had different doses of rucaparib. Some people had it once a day and some had it twice a day. Some people had it with food and some people had it without food.
In part 1 the researchers found:
42 women joined part 2. Everyone had ovarian cancer with a BRCA 1 or BRCA 2 gene change in the cancer cells. They all had 600mg of rucaparib twice a day. The team looked to see if treatment worked. They had the results for 39 women.
They found in:
26 people joined part 3. They all had 600mg rucaparib twice a day. The team looked in more detail at what happened to rucaparib in the body. This is called
Side effects
The researchers looked at the side effects in the different groups. They found that the most common side effects of rucaparib in part 1 and 3, that is those in the groups with any type of solid tumour, were:
The most common side effects of rucaparib in women with ovarian cancer were:
Most of the side effects were manageable. Some people had to stop treatment for a short time until the side effect got better. Or the study team reduced their dose.
Conclusion
The researchers found the best dose of rucaparib to give. They concluded it worked for women with ovarian cancer with a change in BRCA 1 or BRCA 2. And the side effects were manageable.
There are more trials running looking at rucaparib for ovarian cancer.
