Background:

Pheochromocytomas (PHEOs) and paragangliomas (PGLs) are rare neuroendocrine tumors. Symptoms of these tumors can include hypertension, headache, palpitations, and anxiety. There are few treatments for people with advanced PHEOs and PGLs. Researchers want to see if a new drug can help.

Objective:

To compare the usual chemotherapy treatment alone, temozolomide, to using the study drug, olaparib, plus the usual treatment, to see if it could shrink or stabilize these cancers.

Eligibility:

People aged 18 years and older who have advanced (metastatic or unresectable primary) PHEOs or PGLs.

Design:

Participants will be screened with a medical record review and physical exam. They will have an electrocardiogram to assess heart function. They will have blood and urine tests.

Participants will be randomly placed into one of two groups:

-Group 1 will receive treatment in 21-day cycles. They will take temozolomide and olaparib by mouth on Days 1-7 of each cycle, for up to 13 cycles. Then they will take the study drug alone on Days 1-7 of each cycle, until their cancer gets worse.

-Group 2 will receive treatment in 28-day cycles. They will take temozolomide by mouth on Days 1-5 of each cycle, for up to 13 cycles.

Participants will keep a pill diary. They will fill out quality of life assessments. They will give copies of the imaging scans that are done as part of the usual care for their cancer. They will give blood samples for research. They will repeat some screening tests.

After treatment ends, participants will have follow-up visits in person or by phone. Participation will last for 5 years.
