What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores the effectiveness of combining two medications, niraparib and neratinib, for patients with certain advanced cancers, particularly ovarian cancer unresponsive to platinum-based treatments. The main goal is to determine the optimal dose and assess whether these drugs can prevent cancer progression for at least four months. The trial suits those whose ovarian cancer returned within six months of their last platinum treatment and who have tried at least two other therapies. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this novel combination therapy.

Will I have to stop taking my current medications?

The trial requires you to stop taking certain medications that might interact with the study drugs. You must stop using proton pump inhibitors 10 days before starting the trial and discontinue certain other medications at least 2 weeks prior. You can continue taking corticosteroids if your dose has been stable for at least 4 weeks before starting the trial.

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

Research has shown that niraparib is generally well-tolerated by patients with advanced ovarian cancer. In past studies, common side effects included nausea, tiredness, and low blood cell counts, occurring in more than 10% of patients. Most side effects were manageable.

Neratinib, used for other cancers, has caused side effects like diarrhea and liver issues. Medication or dose adjustments can often control these effects.

This study is in an early phase, focusing on finding the right doses of niraparib and neratinib together. Early-phase studies usually involve fewer participants, so the safety data might not be as detailed yet. However, testing both drugs together suggests some confidence in their safety based on past research. Participants will be closely monitored to ensure safety and manage any side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of Niraparib and Neratinib for ovarian cancer because these medications offer a novel approach compared to standard treatments like platinum-based chemotherapy. Niraparib is a PARP inhibitor, which helps prevent cancer cells from repairing their DNA, leading to their death. Neratinib, on the other hand, targets specific proteins involved in cell growth and proliferation, potentially reducing the chance of cancer spreading. This combination could provide a more targeted and effective treatment option for patients, especially those with platinum-resistant ovarian cancer.

What evidence suggests that niraparib and neratinib might be an effective treatment for ovarian cancer?

Research shows that using niraparib and neratinib together can effectively target ovarian cancer cells. In this trial, participants will receive different dose levels of the niraparib and neratinib combination. Studies have found that niraparib helps patients with ovarian cancer live about 11 months without their cancer worsening after initial treatment by blocking a protein that cancer cells need to repair themselves. Neratinib, in contrast, stops certain proteins in cancer cells from aiding their growth. Together, these drugs may enhance each other's effects, offering a promising option for treating ovarian cancer that doesn't respond to platinum-based treatments. Early findings suggest that this combination might help patients go at least four months without their cancer worsening. ^{5 6 7 8 9}

Published Research Related to This Trial

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 phase 3 trial involving 553 patients with platinum-sensitive, recurrent ovarian cancer, niraparib significantly improved progression-free survival compared to placebo, with median durations of 21.0 months versus 5.5 months for patients with gBRCA mutations, and 12.9 months versus 3.8 months for those with homologous recombination deficiency.

While niraparib was effective, it was associated with moderate bone marrow toxicity, with common grade 3 or 4 adverse events including thrombocytopenia (33.8%), anemia (25.3%), and neutropenia (19.6%), which were managed through dose adjustments.

Niraparib is the first PARP inhibitor approved for ovarian cancer treatment in patients without BRCA mutations, showing good tolerability and manageable hematologic side effects, especially with new dose modification guidelines.

Current research is exploring niraparib's effectiveness as a maintenance therapy after platinum-based chemotherapy and in recurrent high-grade serous ovarian cancer, highlighting the need for better biomarkers to identify which patients will benefit most from this treatment.

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.

In a study of 94 patients with non-gBRCA1/2 mutated recurrent ovarian cancer, niraparib maintenance treatment demonstrated effectiveness similar to phase III trials, with a median time to first subsequent treatment of 10.7 months.

Individualized dosing based on patient weight and platelet counts led to fewer dose reductions and interruptions, highlighting the importance of personalized treatment to enhance safety and tolerability.
