APOLLO: A Randomized Phase II Double-Blind Study of Olaparib Versus Placebo Following Curative Intent Therapy in Patients With Resected Pancreatic Cancer and a Pathogenic BRCA1, BRCA2 or PALB2 Mutation
Recruiting now Phase 2 NCT04858334
Run by National Cancer Institute (NCI) · for 18 and older · All sexes
What this study is about
This phase II trial investigates how well the addition of olaparib following completion of surgery and chemotherapy works in treating patients with pancreatic cancer that has been surgically removed (resected) and has a pathogenic mutation in BRCA1, BRCA2, or PALB2. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy.
Who can join (things the study team will check)
✅ You may be able to join if…
- STEP 0 (PRE-REGISTRATION) INCLUSION CRITERIA
- Patient must be >= 18 years of age on day of consent
- Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
- Patient must have a diagnosis of pancreatic cancer and have successfully undergone a curative intent surgical resection and must have no evidence of recurrent disease as determined by the investigator
- NOTE: This includes patients with adenocarcinoma, acinar carcinoma, squamous cell carcinoma adenosquamous and variants thereof. Patients with neuroendocrine tumors are excluded from enrolling
- Patient must (1) be planning to receive, (2) be receiving or (3) have received at least three combined months (i.e., 12 weeks) of perioperative (neoadjuvant, adjuvant or a combination of both) systemic, multi-agent chemotherapy. Patients may have had up to 6 months of perioperative systemic therapy as deemed appropriate by their primary treating medical team (patients can have received radiation or chemoradiation in addition to this 6 month course)
- Patient must be no more than 12 weeks from their most recent treatment (this may be chemotherapy, radiotherapy or surgery)
- Patient must have a known pathogenic or likely pathogenic germline or somatic mutation in BRCA1, BRCA2, or PALB2, as determined by a Clinical Laboratory Improvement Amendments (CLIA) certified or equivalently-accredited laboratory. Mutations must be considered pathogenic or likely pathogenic by a reference database such as ClinVar or OncoKb.org
- STEP 1 (RANDOMIZATION) INCLUSION CRITERIA
- Patient must have met the eligibility criteria outlined above
- Patient must have undergone at least 3 combined months (i.e., 12 weeks) of perioperative (neoadjuvant, adjuvant or a combination of both) systemic, multi-agent chemotherapy. Patients may have had up to 6 months of perioperative systemic therapy as deemed appropriate by their primary treating medical team (patients can have received radiation or chemoradiation in addition to this 6 months course)
- Central expert reviewer must have determined the patient eligible for randomization after review of local genetic testing reports
- If mutation in BRCA1, BRCA2 or PALB2 was identified in tumor tissue and the patient has not previously undergone germline testing, the patient must agree to undergo germline testing
- Patient must have no evidence of recurrent or metastatic pancreatic cancer at the time of randomization as documented by baseline scans obtained =< 4 weeks prior to Step 1 randomization
- Patient must not have previously had evidence of progressive pancreatic cancer while receiving platinum-based therapy
- Patient must be >= 21 days (three weeks) from their last treatment (including chemotherapy radiotherapy or surgery) but =< 84 days (twelve weeks) from their last treatment at the time of Step 1 randomization. Patients who have received neoadjuvant and/or adjuvant radiotherapy are eligible
- Patient must have recovered from any adverse events due to prior anti-cancer therapy (i.e., have no residual toxicities > grade 1 with the exception of alopecia and/or neuropathy)
- Patient must not be receiving any other investigational agents at the time of Step 1 randomization and while on protocol treatment
- Patient must not have any history of allergic reactions attributed to compounds of similar chemical or biological composition to olaparib
- Patient must not have any personal history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of MDS/AML
- Patient must not have any uncontrolled gastrointestinal disorder that would, in the opinion of the investigator, interfere with the ingestion or absorption of olaparib
