What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine whether combining three drugs—durvalumab (an immunotherapy drug), olaparib, and cediranib—can more effectively combat ovarian, primary peritoneal, or fallopian tube cancer compared to the usual treatment. These drugs enhance the immune system and inhibit cancer cells' ability to repair themselves. Participants must have cancer that recurred after responding to platinum-based treatment and should have tried at least two other therapies. Those who have previously used bevacizumab (a cancer treatment drug) and have a BRCA gene mutation might be suitable candidates. The trial will test various combinations of these drugs to identify which best slows cancer progression. As a Phase 2 trial, this research focuses on evaluating the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot use any complementary or alternative medicines, and you should not be on strong inhibitors or inducers of CYP3A4. It's best to discuss your current medications with the study team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that the combination of durvalumab, olaparib, and cediranib is generally safe and well-tolerated. Previous studies have examined these drugs in various combinations. For instance, research has found that using cediranib and olaparib together is safe for treating certain cancers, such as ovarian, fallopian tube, or primary peritoneal cancer.

Durvalumab, a monoclonal antibody, has been tested in various solid tumors and is considered safe to use, even with other medications. Studies on olaparib have also shown it to be well-tolerated, particularly in patients with specific genetic backgrounds.

Although some serious side effects have been reported in trials, they fall within the expected range for cancer treatments. Patients should discuss potential side effects with their doctors to determine if joining a trial is the right choice for them. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine innovative drugs to tackle ovarian cancer in new ways. Unlike the standard treatments like chemotherapy, which directly kill cancer cells, this trial uses a mix of immunotherapy and targeted therapies. Durvalumab is an immunotherapy that helps the immune system recognize and fight cancer cells. Cediranib maleate and olaparib are targeted therapies; cediranib disrupts blood vessel growth that tumors need, while olaparib inhibits a protein that cancer cells use to repair their DNA. By combining these mechanisms, the treatment offers a multi-faceted approach that could enhance effectiveness and reduce the chance of cancer cells developing resistance.

What evidence suggests that this trial's treatments could be effective for ovarian cancer?

Research has shown that combining the drugs durvalumab, olaparib, and cediranib may help treat ovarian cancer that doesn't respond to standard treatments. In this trial, participants will be assigned to different treatment arms to evaluate these combinations. One arm will receive durvalumab, cediranib, and olaparib together. Another arm will receive durvalumab and cediranib, while a separate arm will receive cediranib and olaparib. Studies have found that these combinations can delay cancer growth longer than chemotherapy. Specifically, using durvalumab and olaparib together has doubled the time some patients' cancer remains under control. Additionally, when cediranib is used with olaparib, it has significantly extended the time patients live without the cancer worsening. This suggests that these drug combinations could be a promising option for those with recurring ovarian cancer. ^{2 3 4 5 6}

Published Research Related to This Trial

In a phase II study involving 13 women with recurrent platinum-sensitive ovarian cancer, the combination of olaparib and cediranib showed greater biological activity than olaparib alone, indicated by significant decreases in IL-8 levels and increases in circulating endothelial cells (CEC).

Changes in CEC and IL-8 levels on treatment day 3 were associated with longer progression-free survival, suggesting these biomarkers could help predict patient response to the combination therapy, although further validation is needed.

Lee, JM., Trepel, JB., Choyke, P., et al.[2020]

Cediranib, when used in combination with chemotherapy and as maintenance therapy, significantly improved progression-free survival (PFS) in women with platinum-sensitive ovarian cancer, showing a hazard ratio of 0.56, indicating a 44% reduction in the risk of disease progression.

While the overall survival (OS) analysis was underpowered due to a reduced number of participants, there was a 14% relative reduction in the risk of death, suggesting that cediranib may still provide meaningful benefits in extending survival time for patients with recurrent ovarian cancer.

In the BAROCCO trial involving 123 patients with recurrent platinum-sensitive ovarian cancer, the combination of cediranib and olaparib did not show superior progression-free survival (PFS) compared to paclitaxel chemotherapy, with median PFS of 5.6 months for the continuous cediranib-olaparib group and 3.1 months for the control group.

Despite not outperforming chemotherapy, the cediranib-olaparib combination was associated with a lower rate of treatment discontinuation due to adverse events (5% in the intermittent arm) and offers a potential non-chemotherapy treatment option for heavily pretreated patients.
