Prospective Evaluation of 68Ga-DOTATATE PET/CT, Octreotide and F-DOPA PET Imaging in Ectopic Cushing Syndrome
Summary: Between 10% and 15% of patients with endogenous hypercortisolism (Cushing syndrome) have ectopic (non-pituitary) production of adrenocorticotropin hormone (ACTH) that causes cortisol excess. In approximately 50% of these patients, the tumoral source of ACTH cannot be found initially despite very detailed and extensive imaging, including studies such as computed tomography, magnetic resonance imagi...

1DESCRIPTION
Octreoscan
1) A 10-mL Octreoscan Reaction Vial which contains a lyophilized mixture of:
Pentetreotide has the following structural formula:
Prior to lyophilization, sodium hydroxide or hydrochloric acid may have been added for pH adjustment. The vial contents are sterile and nonpyrogenic. No bacteriostatic preservative is present.
2) A 10-mL vial of Indium In 111 Chloride Solution, which contains: 1.1 mL or 111 MBq/mL (3 mCi/mL) indium In 111 chloride in 0.02N HCl at time of calibration. The vial also contains ferric chloride at a concentration of 3.5 mcg/mL (ferric ion, 1.2 mcg/mL). The vial contents are sterile and nonpyrogenic. No bacteriostatic preservative is present.
Indium In 111 Pentetreotide Injection is prepared by combining the two kit components (
The Indium In 111 Pentetreotide Injection is suitable for intravenous administration as is, or it may be diluted to a maximum volume of 3 mL with 0.9% Sodium Chloride Injection, USP, immediately before intravenous administration. In either case, the radiolabeling yield of Indium In 111 Pentetreotide Injection should be determined before administration to the patient. A method recommended for determining the radiolabeling yield is presented at the end of this package insert (see
1.1Physical Characteristics
Indium In-111 decays by electron capture to cadmium-111 (stable) and has a physical half-life of 2.805 days (67.32 hours) (
The specific gamma ray constant for In-111 is 3.21 R/hr-mCi at 1 cm
Table 3 lists fractions remaining at selected time intervals before and after calibration. This information may be used to correct for physical decay of the radionuclide.

4WARNINGS
DO NOT ADMINISTER IN TOTAL PARENTERAL NUTRITION (TPN) ADMIXTURES OR INJECT INTO TPN INTRAVENOUS ADMINISTRATION LINES; IN THESE SOLUTIONS, A COMPLEX GLYCOSYL OCTREOTIDE CONJUGATE MAY FORM.
The sensitivity of scintigraphy with indium In 111 pentetreotide may be reduced in patients concurrently receiving therapeutic doses of octreotide acetate. Consideration should be given to temporarily suspending octreotide acetate therapy before the administration of Indium In 111 Pentetreotide Injection and to monitoring the patient for any signs of withdrawal.
Hypersensitivity reactions following administration of somatostatin receptor imaging agents predominantly consisted of cutaneous reactions such as rash and pruritus. Reactions reversed either spontaneously or with routine symptomatic management. Less frequently hypersensitivity reactions included angioedema or cases with features of anaphylaxis.
5ADVERSE REACTIONS
The following adverse effects were observed in clinical trials at a frequency of less than 1% of 538 patients: dizziness, fever, flush, headache, hypotension, changes in liver enzymes, joint pain, nausea, sweating, and weakness. These adverse effects were transient. Also in clinical trials, there was one reported case of bradycardia and one case of decreased hematocrit and hemoglobin.
Pentetreotide is derived from octreotide which is used as a therapeutic agent to control symptoms from certain tumors. The usual dose for Indium In 111 Pentetreotide Injection is approximately 5 to 20 times less than for octreotide and is subtherapeutic. The following adverse reactions have been associated with octreotide in 3% to 10% of patients: nausea, injection site pain, diarrhea, abdominal pain/discomfort, loose stools, and vomiting. Hypertension and hyper- and hypoglycemia have also been reported with the use of octreotide.
The following adverse reactions have been identified during postapproval use of Octreoscan. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Immune System Disorders: Hypersensitivity reactions, predominantly rash, pruritus, less frequently angioedema or features of anaphylaxis.
6DOSAGE AND ADMINISTRATION
Before administration, a patient should be well hydrated. After administration, the patient must be encouraged to drink fluids liberally. Elimination of extra fluid intake will help reduce the radiation dose by flushing out unbound, labelled pentetreotide by glomerular filtration. It is also recommended that a mild laxative (e.g., bisacodyl or lactulose) be given to the patient starting the evening before the radioactive drug is administered, and continuing for 48 hours. Ample fluid uptake is necessary during this period as a support both to renal elimination and the bowel-cleansing process. In a patient with an insulinoma, bowel-cleansing should be undertaken only after consultation with an endocrinologist.
The recommended intravenous dose for
The dose should be confirmed by a suitably calibrated radioactivity ionization chamber immediately before administration.
As with all intravenously administered products, Octreoscan should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Preparations containing particulate matter or discoloration should not be administered. They should be disposed of in a safe manner, in compliance with applicable regulations.
Aseptic techniques and effective shielding should be employed in withdrawing doses for administration to patients. Waterproof gloves should be worn during the administration procedure.
Do not administer Octreoscan in TPN solutions or through the same intravenous line.
