The Efficacy and Safety of Temozolomide in Patients With MPPGL (MPPGL)

The Efficacy and Safety of Temozolomide in Patients With Metastatic Pheochromocytoma or Paraganglioma

Metastatic pheochromocytoma / paraganglioma (MPP) are rare while the prognosis was poor. Temozolomide (TMZ) is a novel oral alkylation chemotherapeutic agent. TMZ has been recommended in National Comprehensive Cancer Network (NCCN) Guidelines Version 1.2019 for treating MPP patients.However, studies investigating TMZ efficacy in MPP patients are extremely limited. The largest study involved only 15 patients till date. The safety and efficacy of TMZ treatment in MPP patients need to be verified in larger studies.

Study Overview

Detailed Description

Patients with histologically or radiologically confirmed MPP were enrolled. TMZ was administered orally at an initial daily dose of 150 mg/m2 per day for 5 days, every 28 days. In patients with a good tolerance during the first cycle, the dose was increased to 200 mg/m2 per day for 5 days, every 28 days. Plasma normetanephrine and metanephrine (MNs), 24-hour urinary catecholamine excretion (24hCA) and neuron specific enolase (NSE) were measured at baseline and every 1-3 cycle. Contrast-enhanced computed tomography(CT )of chest, abdomen and pelvis were used to assess measurable target lesions at baseline and every 3 cycles. For patients who only had bone metastases or no measurable target lesions, TMZ efficacy was evaluated by 18F-fluorodeoxyglucose (18F-FDG-PET/CT). The primary endpoint was objective response rate (ORR) per Response Evaluation Criteria In Solid Tumors(RECIST) 1.1/PERCIST1.0. Secondary endpoints included biochemical (catecholamine levels) response rate (BRR), progression-free survival (PFS) and safety. The investigators will try to explore which patients are more suitable for TMZ treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
disease control rate (DCR)
Time Frame: At the end of Cycle 3 (each cycle is 28 days)
Defined for all patients whose tumor met the criteria of CR or PR or stable disease(SD)
At the end of Cycle 3 (each cycle is 28 days)
objective response rate (ORR)
Time Frame: At the end of Cycle 3 (each cycle is 28 days)
Defined for all patients whose tumor met the criteria of Complete Response (CR)and Partial Response (PR)
At the end of Cycle 3 (each cycle is 28 days)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
progression-free survival (PFS)
Time Frame: At least 1 cycle(each cycle is 28 days), up to 100 weeks,From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months
PFS is defined as the time from the first day of treatment to the first documented disease progression per RECIST 1.1 criteria and the Kaplan-Meier curve. Changes in only the largest diameter (unidimensional measurement) of the tumor lesions are used in the RECIST criteria.
At least 1 cycle(each cycle is 28 days), up to 100 weeks,From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months
biochemical response
Time Frame: At the end of Cycle 1 (each cycle is 28 days)
An effective response of 24hCA, MNs or NSE meant that the concentration decreased by more than 40% than the baseline value or decreased to the normal range
At the end of Cycle 1 (each cycle is 28 days)
Incidence of adverse events
Time Frame: At the end of Cycle 1 (each cycle is 28 days)
Incidence of adverse events assessed by Common Terminology Criteria for Adverse Events
At the end of Cycle 1 (each cycle is 28 days)
