Phase I Study of Olaparib and Temozolomide for Ewings Sarcoma or Rhabdoomyosarcoma
Phase I Study of Olaparib and Temozolomide in Adult Patients With Recurrent/Metastatic Ewing's Sarcoma or Rhabdomyosarcoma Following Failure of Prior Chemotherapy
This research study is a Three arm Phase I clinical trial, which tests the safety of an investigational drug or combination of drugs and also tries to define the appropriate dose of the combination of investigational drugs to use for further studies. "Investigational" means that the combination of drugs is being studied. It also means that the FDA has not yet approved the combination of drugs for your type of cancer.
Olaparib works by blocking the activity of a protein called poly (ADP-ribose) polymerase (PARP) which is involved in DNA repair. Cancer cells rely on PARP to repair their DNA and enable them to continue dividing. Olaparib has been used in research studies with other cancers. Information from those other research studies suggests that this drug may help to treat patients with Ewing's sarcoma. The investigational drug olaparib is not approved for any use outside of research studies.
Temozolomide (Temodar) is approved by the FDA for the treatment of a type of brain tumor, glioblastoma. It has been studied in Ewing sarcoma in previous research studies. While it is not approved by the FDA for Ewing sarcoma, it is considered part of standard treatment for relapsed disease.
Irinotecan is approved by the FDA for the treatment of gastrointestinal cancers. It has been studied in Ewing sarcoma in previous research studies. While it is not approved by the FDA for Ewing sarcoma, it is considered part of standard treatment for relapsed disease.
Laboratory studies suggest that the combination of olaparib and temozolomide and/or irinotecan may help kill Ewing sarcoma or rhabdomyosarcoma cells.
In this research study, the investigators are looking for the highest dose of the combination of olaparib and irinotecan and/or temozolomide that can be given safely. The investigators will also begin to collect information about the effects of the combination on Ewing sarcoma and rhabdomyosarcoma.

Detailed Description
If the patient agrees to participate in this research study they will be asked to undergo some screening tests and procedures to confirm that they are eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that they do not take part in the research study. If they have had some of these tests and procedures recently, they may or may not have to be repeated. These tests and procedures will include: a medical history, complete physical examination, performance status, tumor assessment, EKG, blood tests, pregnancy test, confirmation of pathology report and obtain insurance approval to receive temozolomide. If these tests show that the patient is eligible to participate in the research study, they will begin the study drug administration. If they do not meet the eligibility criteria, they will not be able to participate in this research study.
Biomarkers are substances such as genes and proteins that are important biological "indicators" that can be measured in tumor tissue. The investigators would like to look at biomarkers before and after patients receive study drug administration. Comparing the biomarkers from tissue collected before and after receiving study treatments may help us find biomarkers that are associated with response to study treatment or lack of response to study drug administration.
Before the patient starts study drug administration, if the investigators determine that the patient is healthy enough for a biopsy, the patient will undergo a biopsy to provide tumor tissue for the research tests described above. (If it is determined that the patient should not have a biopsy, they can still take part in this research study).
The investigators are looking for the highest doses of olaparib and irinotecan and/or temozolomide that can be administered safely without severe or unmanageable side effects to participants that have Ewing's sarcoma or rhabdomyosarcoma. Therefore, not everyone who participates in this research study will receive the same doses of olaparib, irinotecan, and/or temozolomide. The doses the patients get will depend on the number of participants who have been enrolled in the study before them and how well they have tolerated their doses. The investigators will tell patients how the dose level you receive compares to doses given previously in this study.
Olaparib and irinotecan and/or temozolomide will ge given in cycles of 21 days (3 weeks). Both olaparib and temozolomide are drugs that are taken by mouth. Patients will take olaparib and temozolomide on days 1-7 (week 1) of each cycle. Irinotecan is given by IV, once per day, on days 1-7 of each cycle. Patients will take olaparib twice per day and temozolomide once per day.
The investigators will give patients a drug diary to record the doses of olaparib and temozolomide that they take each day. The diary will also include special instructions for taking olaparib and temozolomide. A member of the study team will show patients how to enter their doses in the diary.
During cycle 1 patients will come to the clinic on Days 1 and 8 (weeks 1 and 2). During cycles 2-6 they will come to the clinic on Day 1 of each cycle. During cycles 8 and beyond they will come to the clinic every 9 weeks.
At each study visit patients will undergo the following procedures: a physical exam, questions about their health (problems, medications, side effects), performance status and blood tests. Additionally, during the visit on Cycle 1, Day 8 patients will have an EKG. 4-6 weeks after starting study drug administration their blood will be tested for its clotting ability on Day 1 of Cycle 2. They will also undergo a biopsy to provide tumor tissue for biomarker research tests. Every 9 weeks they wil have a CT scan or MRI to measure your tumor.
Patients will be asked to return to the clinic about 30 days after stopping study drug. At this visit the following will be done: physical exam, questions about their health, performance status and blood tests. Patients will be asked to return study drug bottles and any unused study drug at this visit.
The investigators would like to keep track of the patients' medical condition for as long as they allow. The investigators would like to do this by either calling patients on the telephone or following them at clinic visits every 3 months. Keeping in touch with patients and checking their condition helps the investigators look at the long-term effects of the research study.
