The Efficacy and Safety of Penpulimab in the Treatment of Metastatic PPGL Patients Who Fail to Other Systemic Treatment

May 31, 2023 updated by: Peking Union Medical College Hospital

A Study on the Efficacy and Safety of Penpulimab in the Treatment of Metastatic Pheochromocytoma/Paraganglioma Patients Who Fail to Other Systemic Treatment

Metastatic pheochromocytoma / paraganglioma (MPP) are rare while the prognosis was poor. Penpulimab is specifically an immune check-point inhibitor of PD1 and has been approved for the treatment of several malignancies.This phase II trial studies the efficacy and safety of penpulimab in the treatment of MPP patients who fail to other systemic therapy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This was a prospective observational study. Patients with histologically or radiologically confirmed MPP and fail to other systemic therapy were enrolled. Penpulimab will be administered intravenously at a dose of 200 mg every 3 weeks. Treatment continued until the patient exhibited radiographic or clinical disease progression or unacceptable adverse events.Plasma normetanephrine and metanephrine (MNs), 24-hour urinary catecholamine excretion (24hCA) were measured at baseline and every 1-3cycle. 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, The efficacy was evaluated by 18F-fluorodeoxyglucose (18F-FDG-PET/CT). The primary endpoint was objective response rate (ORR) and the disease control rate (DCR) 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The objective response rate (ORR)
Time Frame: At the end of Cycle 3(each cycle is 21 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 21 days)
The disease control rate (DCR)
Time Frame: At the end of Cycle 3(each cycle is 21 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 21 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
progression-free survival (PFS)
Time Frame: At least 1 cycle(each cycle is 21 days)
PFS is defined as the time from the first day of treatment to the first documented disease progression per RECIST 1.1 criteria. 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 21 days)
biochemical response
Time Frame: At the end of Cycle 3 (each cycle is 21 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 3 (each cycle is 21 days)
Incidence of adverse events
Time Frame: At the end of Cycle 1 (each cycle is 21 days)
Incidence of adverse events assessed by Common Terminology Criteria for Adverse Events
At the end of Cycle 1 (each cycle is 21 days)
