Survival data from a clinical trial signaled that PARP inhibitors may not work as well as chemotherapy for patients with recurrent ovarian cancer who have received three or more lines of treatment. As a result, FDA approvals have been withdrawn for PARP inhibitors in this setting. This does not affect PARP inhibitor approvals for use as maintenance therapy for ovarian cancer. (Posted 10/4/22)

Questions To Ask Your Health Care Provider
- What are my treatment options if I experience a recurrence after PARP inhibitor treatment?
- Am I eligible for treatment with a PARP inhibitor?
- Am I eligible for maintenance therapy with a PARP inhibitor?
- Do I qualify for any clinical trials?
Open Clinical Trials
The following are studies looking at PARP inhibitors and similar agents for treating people with ovarian cancer.
The following studies are looking at treatment for people with advanced solid tumors.
- NCT05252390: NUV-868 Alone and in Combination With PARP Inhibitors in Patients With Advanced Solid Tumors.This study will test the safety and effectiveness of the experimental drug NUV-868 alone and combined with a PARP inhibitor in people with advanced solid tumors. This study is open to people whose cancer stopped responding or progressed on PARP inhibitors.
- NCT05169437: PARP inhibitor (niraparib) in patients with inherited or tumor PALB2 mutations in advanced solid tumors (PAVO). PAVO is a Phase II study investigating if the PARP inhibitor niraparib is safe and effective for people with an advanced solid tumor who have an inherited PALB2 gene mutation or a tumor with a PALB2 mutation.
- NCT02264678: Ascending Doses of Ceralasertib in Combination With Chemotherapy and/or Novel Anti Cancer Agents. This is a study of ceralasertib administered orally in combination with chemotherapy regimens and/or novel anticancer agents to patients with advanced cancer. The study is enrolling people with inherited mutations, including BRCA1, BRCA2, ATM, RAD51C, RAD51D, and people with tumors that are HRD-positive.
- NCT04644068: Study of AZD5305 as Monotherapy and in Combination With Anti-cancer Agents in Patients With Advanced Solid Malignancies (PETRA). This research is designed to learn whether treatment with a new PARP inhibitor, AZD5305, used alone or in combination with anti-cancer agents is safe, tolerable and has anti-cancer activity in patients with advanced solid tumors. The study is open to people who have previously been treated with PARP inhibitors.
- NCT04267939: ATR Inhibitor Plus Niraparib Study in Advanced Solid Tumors and Ovarian Cancer. This study will look at how well people with advanced solid tumors respond to treatment with the targeted therapy BAY1895344 in combination with the PARP inhibitor niraparib. This study is open to people with inherited mutations in ATM, BRCA1, BRCA2 and other genes. Contact the study coordinator for information about eligibility for people with mutations in other genes.
- NCT04657068: Treatment with ATR Inhibitor for Advanced or Metastatic Solid Tumors. This study will look at how well a new oral targeted therapy known as an ATR inhibitor works on advanced or metastatic solid tumors with mutations in genes that are linked to DNA damage repair. This study is open to people who have an inherited or acquired BRCA or ATM mutation or whose tumors are HRD-positive. This study is open to people whose cancer stopped responding or progressed on PARP inhibitors.
