What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of two drugs, bevacizumab (Avastin) and niraparib (Zejula), to evaluate their effectiveness in treating ovarian or endometrial cancer that has recurred with a specific ARID1A mutation. Researchers aim to determine if these drugs can shrink tumors and assess the treatment's benefits and side effects. Women whose cancer has returned after treatment and who have the ARID1A mutation might be suitable candidates. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant findings.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

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

Research shows that the combination of niraparib and bevacizumab has been studied for safety in treating ovarian cancer. Previous studies found that patients generally tolerated this combination well. The safety profile of using these drugs together aligned with existing knowledge, meaning any side effects were expected and manageable.

Patients experienced some side effects with this combination, such as high blood pressure, tiredness, or nausea. However, these effects are common with many cancer treatments. While these side effects can be uncomfortable, healthcare teams can often help manage them.

Overall, both niraparib and bevacizumab have been used safely in cancer treatment before. Discussing possible side effects with a doctor can help prospective trial participants understand how this treatment might fit into their plan. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Most treatments for ovarian and endometrial cancer typically involve chemotherapy and surgery. But researchers are excited about Bevacizumab and Niraparib because they offer a targeted approach. Niraparib is a PARP inhibitor that interferes with cancer cell repair mechanisms, potentially leading to cancer cell death, and it's taken orally, making it more convenient. Bevacizumab, on the other hand, is a monoclonal antibody that inhibits the growth of blood vessels that supply tumors, administered intravenously. This combination could enhance effectiveness by attacking cancer in two different ways, potentially leading to better outcomes.

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

This trial will compare the effectiveness of Niraparib alone versus the combination of Niraparib and Bevacizumab for treating advanced ovarian and endometrial cancer. Studies have shown that using Niraparib and Bevacizumab together can help treat advanced ovarian cancer. Research indicates that this combination helps patients live longer without their cancer worsening. In one study, patients taking both Niraparib and Bevacizumab lived for 29.4 months, compared to 27.8 months for those taking only Niraparib. Additionally, this combination has shown promising results in delaying cancer progression. The safety of this combination aligns with existing knowledge about these drugs. ^{1 2 4 5 6}

Published Research Related to This Trial

In a study involving patients with newly diagnosed advanced ovarian cancer, the combination of olaparib and bevacizumab significantly improved overall survival (OS) in patients with homologous recombination deficiency (HRD), showing a 5-year OS rate of 65.5% compared to 48.4% for those receiving placebo.

The safety profile of olaparib plus bevacizumab was favorable, with low and balanced incidences of serious conditions like myelodysplastic syndrome and acute myeloid leukemia between treatment groups, confirming its potential as a standard care option for HRD-positive ovarian cancer patients.

Niraparib significantly improves progression-free survival and other key outcomes in patients with recurrent, platinum-sensitive ovarian cancer, based on the phase III NOVA trial involving a randomized, double-blind, placebo-controlled design.

The treatment has a manageable safety profile, with most serious side effects being blood-related issues, which can be effectively managed through dose adjustments.

Niraparib: A Review in Ovarian Cancer. Heo, YA., Duggan, ST.[2019]

In a study of 46 patients with advanced and recurrent epithelial ovarian cancer treated with bevacizumab and chemotherapy over 30 months, the most common adverse events were hypertension (65.2%) and proteinuria (49%), with hypertension typically occurring 2 months after treatment initiation.

Patients with a history of radiation therapy experienced a significantly higher risk of gastrointestinal perforation, indicating that careful consideration is needed when administering bevacizumab to these individuals.

Niraparib significantly improves progression-free survival in patients with recurrent ovarian, fallopian tube, and primary peritoneal cancers, showing 21 months for gBRCA mutation carriers and 9.3 months for non-gBRCA patients compared to much shorter durations with placebo.

As a PARP inhibitor, niraparib works by blocking a key DNA repair mechanism in cancer cells, making it an effective maintenance therapy for patients who have responded to platinum-based treatments.

In a study of 105 patients with newly diagnosed advanced ovarian cancer, the combination of niraparib and bevacizumab as first-line maintenance therapy resulted in a promising progression-free survival (PFS) rate of 62% at 18 months, with even higher rates in patients with homologous recombination deficiency (76%).

The safety profile of this combination therapy was consistent with the known side effects of the individual drugs, with common treatment-related adverse events including thrombocytopenia, fatigue, and anemia, indicating that the treatment is manageable for patients.

Recent advancements in ovarian cancer treatment have introduced several new options that show improved survival rates compared to historical data, marking a significant progress after decades of stagnation.

Three new PARP inhibitors (olaparib, rucaparib, niraparib) have been approved for ovarian cancer, providing new maintenance and recurrence treatment options, alongside expanded uses for bevacizumab in combination chemotherapy regimens.

In a study of 15 heavily pre-treated ovarian cancer patients, bevacizumab demonstrated a tolerable safety profile, with no gastrointestinal perforations observed, which is a significant concern in previous studies.

The treatment resulted in a partial response in 13.3% of patients and stable disease in 40%, with a median overall survival of 15 months, suggesting that bevacizumab may be an effective option for this challenging patient population.

Niraparib, a recently approved treatment for recurrent platinum-sensitive ovarian cancer, has demonstrated a high oral bioavailability of 72.7% in humans, indicating effective absorption when taken orally.

The study involved six patients who received a therapeutic dose of 300 mg of niraparib, followed by a small intravenous dose to measure its levels in the bloodstream, confirming its potential as a convenient oral treatment option.

Bevacizumab, an anti-VEGF therapy, has shown efficacy in treating epithelial ovarian cancers, both as a standalone treatment and in combination with other therapies, based on evidence from Phase II trials involving various patient populations.

While most side effects of bevacizumab, such as proteinuria and hypertension, are mild and manageable, there are serious but rare risks like arterial thromboembolism and gastrointestinal perforation, highlighting the need for careful monitoring during treatment.
