Study of a New InvestigationaI Inhibitor to Treat People with Advanced Solid Tumors

About the Study

The study will test if an investigational treatment, XL309, is safe and works when used alone or in combination with a to treat people with some advanced . The study is looking to enroll adults with certain types of cancer, including those with:

  • or mutations ( breast cancer, cancer and pancreatic cancer);
  • high-grade ovarian, or primary peritoneal cancer; or
  • other with certain genetic mutations.

XL309 is an inhibitor that blocks an enzyme called USP1. Blocking USP1 in cancer cells may prevent tumors from repairing their damaged , causing the cancer cells to die.

Some people in the study will be treated with XL309 in combination with . is an inhibitor that blocks an enzyme called PARP. is approved to treat certain cancers, including some forms of breast cancer, ovarian cancer, pancreatic cancer and cancer.

The use of XL309, alone or in combination with , is being investigated in this clinical trial and has not been approved by the . Safety and efficacy have not been established and are being studied as part of this trial.

What the Study Involves

This is a phase 1, study, which means if you take part in the study, you and your doctor will know which drug(s) are being given. The study will be run in two different parts:

  • Part 1 will focus on learning about the safety of the study drug (XL309) and how the study drug works at different doses.  
  • Part 2 will focus on how the study treatments (XL309 alone or in combination with ) affect the human body and if the treatments work to treat cancer.

If you are eligible and decide to take part in the XL309 study:

  • You may receive the investigational treatment (XL309) alone or in combination with the ().
  • The dose and combination of study drugs will depend on your cancer type and when you enroll in the study.
    • XL309 is taken by mouth, once a day.
    • is taken by mouth, twice a day.
  • You will be in the study for about 4 to 6 months. The length of time you are on the study can depend on how your cancer responds to the treatment, and if you have any side effects. You or your doctor can choose to stop the study treatment at any time.
  • You will visit the doctor for:
    • lab tests and physical exams (about every 1-4 weeks)
    • scans (about every 8 weeks)
