LAnreotide in Metastatic Pheochromocytoma / PARAganglioma (LAMPARA)
United States10 participantsStarted 2019-06-17
Plain-language summary
The objectives of this study are:
* To assess the efficacy of lanreotide given every 4 weeks in participants with advanced or metastatic paraganglioma/ pheochromocytoma.
* To assess the toxicity and safety of lanreotide in participants with advanced or metastatic paraganglioma/ pheochromocytoma.
* To document the effects of lanreotide on markers of biochemical activity in participants with advanced or metastatic paraganglioma/ pheochromocytoma.
Primary endpoints:
• Assess efficacy by estimating the tumor growth rate while a patient is enrolled on study and comparing the growth rates on lanreotide to the pre-enrolment growth rate.
Secondary endpoints include measurement of:
* Overall survival (OS)
* Progression-free survival (PFS)
* Overall response rate (ORR) according to RECIST defined as partial response (PR) + complete response (CR)
* Magnitude of reduction in levels of 24-hour urinary metanephrines, catecholamines and magnitude of reduction in serum chromogranin A, evaluated every two months while enrolled on study.

Inclusion criteria
✓. Male or female at least 18 years of age at the time of first dosing
✓. Patients must give signed informed consent before any study-related activities are conducted.
✓. Patients in the United States must have given written authorization for the release of protected health information in compliance with HIPAA regulations; patients in other countries must provide appropriate authorization as needed by regulatory authorities in each country.
✓. Histologically or cytologically confirmed diagnosis of malignant paraganglioma or pheochromocytoma and either evidence of metastases or unresectability.
✓. Evidence of recent disease progression (radiological, biochemical, symptomatic) while the patient was either not receiving any therapy or was receiving a therapy that was deemed ineffective.
✓. Measurable disease defined as that which can be measured in at least one dimension with a minimum size of 10 mm by CT scan. The patient must also have at least three baseline radiographic studies obtained in the previous twelve months with at least one scan obtained within six weeks of enrollment. If a patient being considered for enrollment on trial has not had three scans performed in the twelve months prior to enrollment and if in the opinion of the investigator a delay of one month will not impact the clinical course, then enrollment on protocol and the start of the lanreotide therapy can be delayed by one month or longer to obtain the additional time point. If in the opinion of the investigator such a delay may have adverse consequences then enrollment on the protocol should not be considered as an option
✓. Confirmation of positive somatostatin receptor status (SRS) by Somatostatin Receptor Scintigraphy. Either of these studies will need to have been performed in the 6 months prior to the screening visit. Only if one has not been performed within the previous 6 months will a SRS study be required. if an SRS is required, it will be performed greater than or equal to 24 hours after a previous injection of subcutaneous octreotide).
✓. Patients may not have had prior octreotide, long acting release (LAR)-octreotide, lanreotide or a therapeutic radiolabeled somatostatin analog (PRRT)
Exclusion criteria
✕. Patient has a history of known allergy or hypersensitivity to:
✕. Treatment with any other investigational drug or with "cytotoxic chemotherapy" within 28 days prior to the start of study therapy (lanreotide) and/or at any time during the patient's participation in the study
✕. Treatment with sunitinib, radiotherapy, a radiolabelled specific somatostatin receptor (SSTR) analog, and/or tumor debulking less than 14 days prior to the start of study therapy (lanreotide). Treatment with metaiodobenzylguanidine (MIBG) therapy less than 90 days prior to the start of study therapy (lanreotide).
✕. History of hepatic arterial embolization or hepatic arterial chemoembolization less than 28 days prior to the start of study therapy (lanreotide). Measurable disease shall exist outside of treated lesions for eligibility.
✕. History of hepatic selective internal radiation therapy (e.g. Sir-spheres) less than 90 days prior the start of study therapy (lanreotide). Measurable disease shall exist outside the liver for eligibility.
✕. Uncontrolled diabetes (defined as inability to maintain fasting blood glucose levels below 200 mg/dL despite best medical therapy, within last 28 days prior to screening) and/or hypertension (defined as inability to maintain blood pressure levels below systolic 140 mm Hg and/or diastolic 90 mm Hg on at least three antihypertensive medications, within last 28 days prior to screening).
✕. Renal impairment (glomerular filtration rate less than 30 ml/min/1.73m2) and/or liver impairment (serum total bilirubin greater than 1.5 x ULN, or greater than 2.5 x ULN if liver metastases)
✕. Uncontrolled cardiac disease (acute myocardial infarction, unstable angina or hospitalization for decompensation of congestive heart failure within the 28 days prior to the start of study therapy (lanreotide).
