Lanreotide is FDA approved for certain kinds of neuroendocrine tumors. This study seeks to
determine if lanreotide is beneficial for patients with paraganglioma/ pheochromocytoma.
Given the rarity of pheochromocytoma/paraganglioma that precludes the conduct of a randomized
clinical trial in a timely manner, a novel method for assessing efficacy is being proposed.
Efficacy will be assessed by estimating the tumor growth rate while a patient is enrolled on
study and comparing the growth rates on lanreotide to the pre-enrollment growth rates. The
method of analysis that will be used has been previously described. For this assessment a
minimum of three tumor measurements will be required.
For inclusion in the study, patients must fulfill all of the following criteria:
1. Male or female at least 18 years of age at the time of first dosing
2. Patients must give signed informed consent before any study-related activities are
3. 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.
4. Histologically or cytologically confirmed diagnosis of malignant paraganglioma or
pheochromocytoma and either evidence of metastases or unresectability.
5. Evidence of recent disease progression (radiological, biochemical, symptomatic) while
the patient was either not receiving any therapy or was receiving a therapy that was
6. 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
7. 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
8. Patients may not have had prior octreotide, long acting release (LAR)-octreotide,
lanreotide or a therapeutic radiolabeled somatostatin analog (PRRT)
9. Eastern Cooperative Oncology Group (ECOG) 0-2.
10. Life expectancy of greater than 12 weeks.
11. Patients must have prothrombin time (PT)/international normalized ratio (INR)/partial
thromboplastin time (PTT) within 2 x the upper limit
12. Patients may have had prior radiation therapy. A minimum of 42 days must have elapsed
between the end of radiotherapy and registration onto the study. Measurable disease
must exist outside of the radiation field for eligibility.
13. Previous surgery: Previous major surgery is permitted provided that it was performed
at least 28 days prior to patient registration.
14. Laboratory requirements [parameter limits]: Absolute granulocyte count (AGC) greater
than 1.5 x 109/L; platelet count greater than100 x 109/L; serum bilirubin less than
1.5 x upper limit of normal (ULN); serum aspartate aminotransferase (AST) and alanine
aminotransferase (ALT) less than 2.5 x ULN; serum amylase less than1.5 x ULN; serum
lipase less than 1.5 x ULN; serum calcium less than 3 mmol/L; serum creatinine less
than 1.5 x ULN
15. If female, the patient must not be pregnant (confirmed by negative pregnancy test) and
must have the following documented via verbally given history:
- At least 1 year postmenopausal (natural cessation of menses), or
- Surgically sterile (if by tubal ligation, surgery must have been performed more
than 3 months prior to entry into the study), or
- If of childbearing potential and sexually active, she must be using or agree to
use an acceptable form of contraception (oral, injected, transdermal or implanted
contraceptives, diaphragm or barrier method with spermicidal and/or intrauterine
device); local methods such as condoms or sponges/vaginal tablets are only to be
used as an additional form of contraception.
16. If the male patient has a partner of childbearing potential and he is sexually active,
he must be using or agree to use a barrier method of contraception (condom with

willing to comply with the study instructions
