Safety and Efficacy of Olaparib Combined with Agents Targeting DNA Damage Repair Compared to Olaparib Alone

NOTE: This study is no longer enrolling patients. 

About the Study

The purpose of this study is to assess the efficacy and safety of treatment with the , combined with the drug Ceralasertib compared with olaparib alone for patients with .

The study outcomes will be analyzed for the following three patient populations:

  1. Patients with or gene mutations.
  2. Patients with mutations in any of the other genes, and no mutation in BRCA1 and no mutation in BRCA2.
  3. Patients with no detected tumor mutations in any of the repair (HRR) genes. Homologous recombination is a method that normal cells use to repair damage to .

Type of Study

This is an open label, , two-arm study that will enroll 350 people. 

  • The study has two arms. All participants will be placed into one of two groups. 
    • One group of patients will receive olaparib as a single agent. 
    • One group of patients will receive olaparib combined with the drug ceralasertib.
  • This is a randomized study, which means that participants will be placed into one of the two groups by chance. Neither patients nor the research doctor will choose the group participants are placed in.
  • The study is . All participants will know which group they are assigned to.

What the Study Entails

Eligible patients will be randomized into one of two treatment arms:

  • Arm #1: Study participants will take 300mg olaparib orally in 28-day cycles.
  • Arm #2: Study participants will take 300mg olaparib orally in a 28-day cycle. These participants will take Ceralasertib 160 mg from Day 1 to Day 7 (inclusive) of every 28-day cycle.

Patients will remain on the study until date of first documented progression of disease or an that keeps the participant from continuing on the study.
