Testar tillägget av ett läkemedel mot cancer, Olaparib, till den vanliga kemoterapin (Temozolomid) för avancerad neuroendokrin cancer

11 november 2026 uppdaterad av: National Cancer Institute (NCI)

En prospektiv, multi-institutionell fas II-studie som utvärderar temozolomid vs. temozolomide och olaparib för avancerade feokromocytom och paragangliom

This phase II trial studies how well the addition of olaparib to the usual treatment, temozolomide, works in treating patients with neuroendocrine cancer (pheochromocytoma or paraganglioma) that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Poly (adenosine diphosphate [ADP]-ribose) polymerases (PARPs) are proteins that help repair deoxyribonucleic acid (DNA) mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving olaparib with temozolomide may shrink or stabilize the cancer in patients with pheochromocytoma or paraganglioma better than temozolomide alone.

Detaljerad beskrivning

PRIMARY OBJECTIVE:

I. To compare the progression-free survival (PFS) of patients with advanced pheochromocytoma and paraganglioma (APP) receiving temozolomide (dose dense) and olaparib to that of patients receiving temozolomide (pulse dose) alone.

SECONDARY OBJECTIVES:

I. To compare the overall survival (OS) of patients with APP receiving temozolomide (dose dense) and olaparib versus (vs.) temozolomide (pulse dose) alone.

II. To compare the objective response rate (ORR) associated with temozolomide (dose dense) and olaparib vs. temozolomide (pulse dose) alone in patients with APP.

III. To evaluate and compare the toxicity profile of temozolomide-based combinations (temozolomide [dose dense] and olaparib vs. temozolomide [pulse dose]) in patients with APP using Common Terminology Criteria for Adverse Events (CTCAE) and Patient-Reported Outcomes (PRO)-CTCAE.

OTHER OBJECTIVE:

I. Results of the primary analysis will be examined for consistency, while taking into account the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue.

EXPLORATORY OBJECTIVES:

I. To assess biochemical response: serum catecholamines and metanephrines; urine catecholamines and metanephrines.

II. To assess biomolecular markers associated with clinical outcome: germline succinyl dehydrogenase (SDH) mutations and tumor status of the repair enzyme methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive temozolomide orally (PO) once daily (QD) and olaparib PO twice daily (BID) on days 1-7. Treatment with temozolomide repeats every 21 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Cycles of olaparib repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) with contrast or magnetic resonance imaging (MRI) throughout the study and undergo mandatory collection of blood samples prior to treatment. Patients may optionally undergo collection of blood samples at the time of progression.

ARM II: Patients receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT with contrast or MRI throughout the study and undergo mandatory collection of blood samples prior to treatment. Patients may optionally undergo collection of blood samples at the time of progression.

Patients discontinuing treatment due to reasons other than disease progression are followed every 12 weeks until disease progression, then every 6 months until 5 years after registration. Patients discontinuing treatment due to disease progression are followed every 6 months for 5 years after registration.

Vad mäter studien?

Primära resultatmått

Resultatmått
Åtgärdsbeskrivning
Tidsram
Progression-free survival (PFS)
Tidsram: From randomization to the first documentation of disease progression (per Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1) or death, assessed up to 5 years

Will be compared between treatment arms using the un-stratified log-rank test at one-sided level of 0.11 and the p-value will be used for decision making. The hazard ratio will be estimated using a Cox proportional hazards model and the 95% confidence interval for the hazard ratio will be provided. Results from a stratified analysis will also be provided. Kaplan-Meier methodology will be used to estimate the median PFS for each treatment arm, and Kaplan-Meier curves will be produced. Brookmeyer-Crowley methodology will be used to construct the 95% confidence interval for the median PFS for each treatment arm.
From randomization to the first documentation of disease progression (per Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1) or death, assessed up to 5 years

Tidsram
Overall survival (OS)
Tidsram: From randomization to death due to any cause, assessed up to 5 years

Patients who are alive will be censored at last follow-up. The distribution of survival time will be estimated using the method of Kaplan-Meier. OS will be compared between treatment arms using the log-rank test. OS medians, survival rates and hazard ratio will be estimated along with 95% confidence intervals.
From randomization to death due to any cause, assessed up to 5 years
Objective response
Tidsram: Up to 5 years

Will be assessed by RECIST version 1.1 criteria. Will be estimated using objective response rate where objective response rate is defined as the number of evaluable patients achieving a response (partial response or complete response per RECIST version 1.1) during treatment with study therapy divided by the total number of evaluable patients. Rates of response will be compared across arms using a Chi-Square Test for Proportion. Point estimates will be generated for objective response rates within each arm along with 95% binomial confidence intervals.
Up to 5 years
Incidence of adverse events
Tidsram: Up to 5 years

Will be assessed per National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The term toxicity is defined as adverse events that are classified as possibly, probably, or definitely related to study treatment. Toxicities will be evaluated via the ordinal Common Terminology Criteria for Adverse Events standard toxicity grading. Similarly, scores (0-4) and the maximum score for each Patient-Reported Outcomes-CTCAE item will be recorded for each patient.
Up to 5 years

Tidsram
Biochemical response
Tidsram: Up to 5 years

Levels of chromogranin A, urine and/or plasma catecholamines and metanephrines may predict response to therapy. The proportion of patients with a biochemical response of partial response or better, as determined by plasma and/or urine catecholamines and metanephrines, will be calculated, and a 95% confidence interval will be placed on this proportion. For each factor, we will calculate the mean +/- standard deviation, minimum, maximum, and quartiles; in addition, we will generate box and whisker plot.
Up to 5 years
Biomolecular markers associated with clinical outcome
Tidsram: Up to 5 years

Will analyze for methyltransferase (MGMT) methylation expression in archival tumors and correlate with the radiographic response rate in metastatic pheochromocytoma/paraganglioma. This is hypothesis generated box and whisker plot.
Up to 5 years
