What side effects are associated with this type of intervention?

Common treatments for ovarian tumors, particularly PARP inhibitors like Niraparib, often have side effects such as anemia, thrombocytopenia (low platelet count), and neutropenia (low neutrophil count). Other side effects may include nausea, fatigue, and gastrointestinal issues like diarrhea. Additionally, treatments like bevacizumab can cause hypertension and proteinuria, while pazopanib is associated with hypertension, diarrhea, and hepatotoxicity. These side effects are important considerations for patients undergoing treatment for ovarian tumors.

What prior FDA approvals exist?

The FDA has approved several PARP inhibitors for the treatment of ovarian tumors, particularly in cases of recurrent or platinum-sensitive ovarian cancer. Niraparib, a PARP inhibitor, is approved for maintenance therapy in patients with recurrent ovarian cancer who have responded to platinum-based chemotherapy. Other PARP inhibitors include olaparib and rucaparib. Olaparib is approved for maintenance treatment in patients with BRCA-mutated advanced ovarian cancer, while rucaparib is approved for both treatment and maintenance therapy in recurrent ovarian cancer. These approvals highlight the role of PARP inhibitors in extending progression-free survival in ovarian cancer patients.

What other types of research exist?

Promising alternatives to Niraparib for ovarian tumor patients include Olaparib and Rucaparib, both of which are PARP inhibitors with demonstrated efficacy in clinical trials. Additionally, combination therapies such as Cediranib with Olaparib have shown potential. Investigational options like heated intraperitoneal chemotherapy (HIPEC) and other targeted therapies may also be considered.

Participant is currently receiving treatment with niraparib (as monotherapy or in combination) in a GlaxoSmithKline/TESARO-sponsored study that has fulfilled the requirements for the primary objective.

Be older than 18 years old

Must not have

Participant has been permanently discontinued from niraparib treatment in the parent study for any reason.

Summary

This trial provides continued access to niraparib for patients already receiving it in certain studies and aims to understand its ongoing safety. Niraparib helps stop cancer cells from repairing their DNA, which can kill the cancer. Niraparib is approved for use in ovarian cancer patients who respond to specific treatments.

Who is the study for?

This trial is for individuals already participating in certain GlaxoSmithKline/TESARO-sponsored studies of Niraparib, who are seeing benefits from the treatment. They must be able to follow the study plan and agree to use effective contraception if they can have children. Pregnant or breastfeeding individuals, those planning to conceive, or with unresolved toxicities from previous Niraparib treatments cannot join.

What is being tested?

The trial provides continued access to Niraparib for participants benefiting from it in prior related studies. It aims to gather more data on the long-term safety of this cancer medication when used by patients with tumors, breast cancer, or ovarian tumors.

What are the potential side effects?

While not specified here, common side effects of Niraparib may include nausea, fatigue, blood cell count changes leading to anemia or risk of infection, heart palpitations, insomnia and constipation. Each patient's experience may vary.

Experimental Treatment

Group I: Participants receiving niraparibExperimental Treatment1 Intervention

Participants will receive niraparib once a day, continuously throughout each 90-day cycle until one of the following occurs: disease progression, unacceptable toxicity, initiation of new anticancer therapy that was not part of the parent study, withdrawal of consent, discontinuation at the discretion of the Investigator, noncompliance with protocol, death, or discontinuation for any other reason. The doses provided in this long-term treatment extension study will be those defined in the parent study for each enrolled participant. The starting dose of niraparib will be the same as the assigned dose and regimen that were given in the parent study.

Other Research

The most common treatments for ovarian tumors include PARP inhibitors, angiogenesis inhibitors, and platinum-based chemotherapies. PARP inhibitors, such as Niraparib, work by blocking the PARP enzyme, which helps repair DNA damage in cells. This is particularly effective in cancer cells with BRCA mutations, leading to cell death and reduced tumor growth. Angiogenesis inhibitors, like bevacizumab, prevent the formation of new blood vessels that tumors need to grow and spread. Platinum-based chemotherapies, such as carboplatin, cause DNA damage that cancer cells cannot repair, leading to cell death. These treatments are crucial for ovarian tumor patients as they target the cancer cells' ability to repair and sustain themselves, thereby improving survival rates and quality of life.
