Trial Summary

What is the purpose of this trial?

This phase II trial studies the possible benefits of treatment with different combinations of the drugs durvalumab, olaparib and cediranib vs. the usual treatment in patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back after a period of improvement with platinum therapy (recurrent platinum resistant). Usual treatment is the type of treatment most patients with this condition receive if they are not part of a clinical study. Combination therapies studied in this trial include MEDI4736 (durvalumab) plus olaparib and cediranib, durvalumab and cediranib, or olaparib and cediranib. Monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumors cells to grow and spread. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Cediranib may stop the growth of tumor cells by blocking VEGF (an enzyme). needed for cell growth. Giving different combinations of durvalumab, olaparib and cediranib may work better in increasing the duration of time that the cancer does not progress compared to the usual treatment.

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.

What data supports the effectiveness of the drug combination Cediranib Maleate, Durvalumab, Imfinzi, MEDI 4736, MEDI-4736, MEDI4736, Olaparib, Lynparza for ovarian cancer?

Research shows that combining cediranib and olaparib can improve outcomes in women with recurrent ovarian cancer compared to using olaparib alone. Additionally, combining olaparib with durvalumab showed promising response rates in patients with specific genetic mutations. ^{1 2 3 4 5}

What safety data exists for the triple combination immunotherapy involving Cediranib, Durvalumab, and Olaparib?

Cediranib and Olaparib have been studied together in ovarian cancer, showing some common side effects like nausea, fatigue, and anemia (low red blood cell count). Olaparib alone has been associated with more serious conditions like myelodysplastic syndrome (a blood disorder) and acute myeloid leukemia (a type of blood cancer) in a small percentage of patients. ^{1 3 4 6 7}

How is the triple combination drug for ovarian cancer different from other treatments?

The triple combination drug for ovarian cancer is unique because it combines cediranib, durvalumab, and olaparib, which work together to target cancer cells in different ways: cediranib blocks blood vessel growth to tumors, durvalumab helps the immune system attack cancer cells, and olaparib interferes with cancer cell repair. This combination aims to improve treatment outcomes for patients with specific genetic profiles, such as those with HRR mutations, compared to using these drugs individually. ^{1 3 4 5 6}

Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo ECHO or MUGA during screening and as clinically indicated on study. Patients also undergo collection of blood and CT with contrast during screening, and CT or MRI scans throughout the trial.

Group IV: Arm I (paclitaxel, doxorubicin, topotecan hydrochloride)) Active Control 9 Interventions

Patients receive paclitaxel IV over 60 minutes on days 1, 8, and 15, or pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1, or topotecan hydrochloride IV over 30 minutes on days 1, 8 and 15 or days 1-5 per the discretion of the treating physician. Cycles repeat every 21 or 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo ECHO or MUGA during screening and as clinically indicated on study.

Findings from Research

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.

Olaparib, a PARP inhibitor, showed a 36% objective response rate in women with relapsed ovarian cancer and a germline BRCA1/2 mutation, even after they had undergone multiple lines of chemotherapy, indicating its efficacy in this challenging patient population.

The median duration of response to olaparib was 7.4 months, and the safety profile was consistent across patients who had received three or more lines of prior chemotherapy, with similar rates of serious adverse events.

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.

In a phase IIb trial involving 60 women with platinum-resistant recurrent ovarian cancer, the combination of cediranib and olaparib showed a modest objective response rate (ORR) of 15.3%, indicating some clinical activity in this heavily pretreated population.

The treatment was associated with significant safety concerns, as 73.3% of patients experienced grade ≥3 adverse events, highlighting the need for careful monitoring and further research into biomarkers that could predict treatment response.

In a study involving 30 patients with platinum-resistant ovarian cancer and HRR gene mutations, both olaparib-based combinations showed promising efficacy, with objective response rates of 50.0% for olaparib plus cediranib and 42.9% for olaparib plus durvalumab.

Biomarker profiling revealed that specific markers, such as high vascular endothelial growth factor for cediranib and immune markers for durvalumab, could guide treatment decisions, potentially enhancing outcomes for patients based on their individual biomarker status.

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.

Olaparib, approved by the FDA for patients with advanced ovarian cancer carrying BRCA mutations, showed a 34% objective response rate in a trial of 137 patients who had undergone three or more prior chemotherapy treatments, with a median response duration of 7.9 months.

Common side effects included anemia, nausea, and fatigue, with a small risk (2%) of developing myelodysplastic syndrome or acute myeloid leukemia, indicating the need for careful monitoring during treatment.
