Phase I Study of the Oral PI3kinase Inhibitor BKM120 or BYL719 and the Oral PARP Inhibitor Olaparib in Patients With Recurrent Triple Negative Breast Cancer or High Grade Serous Ovarian Cancer

February 8, 2021 updated by: Ursula A. Matulonis, MD, Dana-Farber Cancer Institute

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational combination of drugs. Phase I studies also try to define the appropriate dose of the investigational combination to use for further studies. "Investigational" means that the combination of these drugs is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved either of these drugs nor the combination of being tested for use in patients, including people with your type of cancer.

BKM120, BYL719 and olaparib are drugs that may stop cancer cells from growing abnormally. These drugs when combined in laboratory experiments with animals, have demonstrated anti-cancer activity. Information from these other research studies suggests that the following agents BKM120, BYL719 and olaparib, may help to shrink tumor cells in the types of cancers being studied in this research study.

In this research study, the investigators are looking for the highest dose that can be given safely and also to see if the combination of BKM120 or BYL719 and olaparib is effective in treating your type of cancer.

Detailed Description

During this study, additional tests will be performed on a sample of your original tumor that has been stored in your institutions tissue banks. These tests will be performed on tumor tissue samples from previous biopsies or surgeries for your cancer. The research done on these samples will involve looking at DNA and proteins in your cancer to see if researchers can learn more about your type of cancer and understand how this combination of drugs might work on your tumor. Testing of this sample will not require you to undergo any additional research procedures.

Approximately 2 tablespoons of blood will be collected for research testing. This testing will involve looking at DNA and proteins in your blood to compare them with those seen in your cancer. This will be drawn before you begin taking the study drug.

You may also participate in an optional blood test for the BRCA gene. The BRCA gene test is a blood test that uses DNA analysis to see changes in either one of two breast cancer genes, known as BRCA1 or BRCA2. After having a BRCA gene test performed, you learn whether you carry an inherited BRCA gene mutation. If your blood is tested for the BRCA gene, the results will be reported to your study doctor who will share the results with you and provide information related to your personal risk of breast cancer. Having a BRCA gene mutation is rare, occurring in only about 1 in 1000 people. Inherited BRCA gene mutations are responsible for less than 5 to 10 percent of breast cancers and about 10 to 15 percent of ovarian cancers.

Participants in the dose expansion portion of the study may be asked to have a tumor biopsy done. The dose expansion phase for the combination of BKM120 and Olaparib has been determined. The combination of BYL719 and Olaparib is currently in the dose escalation phase and the dose expansion phase has not been determined. Before and after you begin taking BKM120 (or BYL719) and olaparib, your doctor may also ask you to participate in an optional study where you would have tumor biopsies done.

Participation in the tumor biopsy and blood test for the BRCA gene are optional, and whether you consent or refuse to undergo these additional tests will not affect your participation in the main research study.

Since the investigators are looking for the highest dose of the study drug that can be administered safely without severe or unmanageable side effects in participants that have high grade serious ovarian cancer or triple negative breast cancer, not everyone who participates in this research study will receive the same dose of the study drug. The dose you get will depend on the number of participants who have been enrolled in the study before you and how well they have tolerated their doses.

All drugs are in oral form. If you take part in this research study, you will be given a study dosing calendar for each drug for each treatment cycle. Each treatment cycle lasts 4 weeks. BKM120 or BYL719 should be taken once daily in the morning, one hour after a light meal. Olaparib should be taken twice a day continuously, about twelve hours apart. The olaparib morning dose should be taken at the same time as BKM120 or BYL719 one hour after a light meal. The evening dose can also be taken one hour after a light meal or on an empty stomach either 1 hour before or 2 hours after meals. If you vomit either or both medications, record this on your diary and do not take another dose that day.

The investigators will assess your tumor by CT or MRI scan every 8 weeks. During Cycle 1, you will come into the clinic every week, and during cycle 2, you will come into clinic every 2 weeks. For all cycles thereafter, you will come in once every 4 weeks.

During study visits you will undergo some or all of the following: evaluation of performance status, recording of any healthy problems, physical exam including vital signs, list of medications taken since last visit, questionnaire to evaluate anxiety and depression, routine blood tests, research blood tests, Electrocardiogram and optional biopsy.

You will remain in this research study as long as you are benefitting from study treatment. If you are removed from the research study for any reason you may be followed for up to one year.
