1 Indications And Usage

NETSPOT, after radiolabeling with Ga 68, is indicated for use with positron emission tomography (PET) for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adult and pediatric patients.

2.1 Radiation Safety

Drug HandlingAfter reconstitution and radiolabeling, handle the Ga 68 dotatate injection with appropriate safety measures to minimize radiation exposure [see






Warnings and Precautions (5.1)
]. Use waterproof gloves, effective radiation shielding and appropriate safety measures when preparing and handling Ga 68 dotatate injection.





Radiopharmaceuticals should be used by or under the control of physicians who are qualified by specific training and experience in the safe use and handling of radionuclides, and whose experience and training have been approved by the appropriate governmental agency authorized to license the use of radionuclides.Patient PreparationInstruct patients to drink a sufficient amount of water to ensure adequate hydration prior to administration of Ga 68 dotatate. Drink and void frequently during the first hours following administration to reduce radiation exposure.

In adults and pediatric patients, the recommended amount of radioactivity to be administered for PET imaging is 2 MBq/kg of body weight (0.054 mCi/kg) up to 200 MBq (5.4 mCi). After reconstitution with Ga 68 chloride eluate from an Eckert & Ziegler GalliaPharm Germanium 68/Gallium 68 (Ge 68/Ga 68) generator and buffer, [see






Drug Preparation (2.3)
], administer Ga 68 dotatate by intravenous injection (bolus).





Verify the injected radioactivity by measuring the radioactivity of the vial containing the Ga 68 dotatate injection with a dose calibrator before administration to the patient [see






Administration (2.4)
]. Ensure that the injected radioactivity is within ±10% of the recommended dose.

2.3 Drug Preparation

  • The NETSPOT kit is supplied as 2 vials and an accessory cartridge [see
  • Dosage Forms and Strengths (3)
  • ] which allows for direct preparation of Ga 68 dotatate injection with the eluate from an Eckert & Ziegler GalliaPharm Germanium 68/Gallium 68 (Ge 68/Ga 68) generator. The Eckert & Ziegler GalliaPharm Ge 68/Ga 68 generator (“GalliaPharm generator”) is not supplied with the NETSPOT kit. The safety and efficacy of the Ga 68 dotatate injection drug product prepared from the NETSPOT kit has been established only when using a Ga 68 chloride solution eluted from the GalliaPharm generator.
  • Components of the kit:Vial 1 (reaction vial with lyophilized powder) contains: 40 mcg dotatate, 5 mcg 1,10-phenanthroline; 6 mcg gentisic acid; 20 mg mannitol.
  • Vial 2 (buffer vial) contains: 60 mg formic acid; 56.5 mg sodium hydroxide and water for injection.
  • Accessory cartridge contains: 660 mg porous silica. The accessory cartridge reduces the amount of Ge 68 potentially present in generator eluate.Prepare Ga 68 dotatate for intravenous injection according to the following aseptic procedure (Figure 1):Use suitable shielding to reduce radiation exposure.Wear waterproof gloves.Set the temperature of the shielded dry bath to 203 °F (95 °C), and wait for the temperature to reach the set point and stabilize.Prepare a syringe containing 5 mL of 0.1 N sterile HCl, to be used for elution of the GalliaPharm generator. Use 0.1N sterile HCl supplied by the generator manufacturer. Test periodically (weekly) the Ga 68 chloride eluate for Ge 68 breakthrough by suitable method. Ge 68 breakthrough and other gamma emitting radionuclides should be ≤ 0.001%. The Ga 68 chloride is sterile as eluted from the GalliaPharm generator.Remove the cap from

  • Remove the cap from the
  • Vial 2 (buffer vial), swab the top of the vial with alcohol to disinfect the surface, and allow the stopper to dry.
  • Using a 1 mL sterile syringe, withdraw the required volume of the reaction buffer from
  • Vial 2. Calculate the volume (in mL) by multiplying the volume of HCl used for the elution of the generator in mL by its molarity:
  • Reaction buffer volume in mL = HCl volume in mL x HCl molarity (for the GalliaPharm generator eluate, 5 mL x 0.1 N = 0.5 mL of reaction buffer).
  • Connect the top of the cartridge to the male luer of the outlet line of the GalliaPharm generator. Connect the bottom of the cartridge with a sterile needle.Connect
  • Vial 1 to the outlet line of the GalliaPharm generator by pushing the needle through the rubber septum and place the vial in a lead shield container.
  • Elute the generator directly into the Vial 1 through the cartridge and the needle according to the instructions for use of the GalliaPharm generator that are supplied by Eckert & Ziegler, in order to reconstitute the lyophilized powder with 5 mL of eluate. Perform the elution manually or by means of a pump.At the end of the elution, disconnect the generator from
  • Vial 1 by removing the needle from the rubber septum, and immediately (do not delay buffer addition more than 10 min) add the kit reaction buffer in the 1 mL sterile syringe (the amount of reaction buffer was determined from Step h). Withdraw the syringe and the 0.22 micron sterile air venting filter, and then using a tong, move
  • Vial 1 to the heating hole of the dry bath, and leave the vial at 203 °F (95 °C, not to exceed 98 °C) for at least 7 minutes (do not exceed 10 minutes heating) without agitation or stirring. Do not invert or shake the reaction vial because contact between the solution and the rubber septum can lead to zinc leaching and can interfere with binding of Ga 68 to the peptide.
  • After 7 minutes, remove the vial from the dry bath, place it in an appropriate lead shield and let it cool down to room temperature for approximately 10 minutes.Assay the whole vial containing the Ga 68 dotatate injection for total radioactivity concentration using a dose calibrator and record the result.Perform the quality controls according to the recommended methods in order to check the compliance with the specifications [see
  • Dosage and Administration (2.5)].
  • Prior to use, visually inspect the solution behind a shielded screen for radioprotection purposes. Only use solutions that are clear without visible particles.Keep the vial containing the Ga 68 dotatate injection upright in a radio-protective shield container at a temperature below 77 °F (25 °C) until use.After addition of Ga 68 chloride to the reaction vial, use Ga 68 dotatate injection within 4 hours.

2.4 Administration

Prior to use, visually inspect the prepared Ga 68 dotatate injection behind a lead glass shield for radioprotection purposes. Only use solutions that are clear without visible particles. Using a





single-dose syringe fitted with a sterile needle and protective shielding, aseptically withdraw the prepared Ga 68 dotatate injection prior to administration. Measure the total radioactivity in the syringe by a dose calibrator immediately prior to administration. The dose calibrator must be calibrated with National Institute of Standards and Technology (NIST) traceable standards.





Handle and dispose radioactive material in accordance with applicable regulations.

2.5 Specifications And Quality Control

  • ITLC SG: Non-complexed Ga 68 species, Rf = 0 to 0.1; Ga 68 dotatate, Rf = 0.8 to 1

2.6 Image Acquisition

For Ga 68 dotatate PET imaging, the acquisition must include a whole body acquisition from skull to mid-thigh. Images can be acquired 40 to 90 minutes after the intravenous administration of the Ga 68 dotatate. Adapt imaging acquisition delay and duration according to the equipment used, and the patient and tumor characteristics, in order to obtain the best image quality possible.

2.7 Image Interpretation

Ga 68 dotatate binds to somatostatin receptors. Based upon the intensity of the signals, PET images obtained using Ga 68 dotatate indicate the presence and density of somatostatin receptors in tissues. Tumors that do not bear somatostatin receptors will not be visualized. Increased uptake in tumors is not specific for NET

2.8 Radiation Dosimetry

  • Estimated radiation absorbed doses per injection activity for organs and tissues of adult patients following an intravenous bolus of Ga 68 dotatate are shown in Table 2. Estimated radiation effective doses per injection activity for adult and pediatric patients following an intravenous bolus of Ga 68 dotatate are shown in Table 3.Gallium Ga 68 decays with a half-life of 68 minutes to stable zinc Zn 68:89% through positron emission with a mean energy of 836 keV followed by photonic annihilation radiations of 511 keV (178%), 10% through orbital electron capture (X-ray or Auger emissions), and 3% through 13 gamma transitions from 5 exited levels.The effective radiation dose resulting from the administration of 150 MBq (4.05 mCi) [within the range of the recommended Ga 68 dotatate injection dose] to an adult weighing 75 kg, is about 3.15 mSv. For an administered activity of 150 MBq (4.05 mCi) the typical radiation dose to the critical organs, which are the urinary bladder wall, the spleen and the kidneys/adrenals, are about 18, 16 and 12 mGy, respectively. Because the spleen has one of the highest physiological uptakes, higher uptake and radiation dose to other organs or pathologic tissues may occur in patients with splenectomy.1. Physical data

4 Contraindications

None

5.1 Radiation Risk

Ga 68 dotatate contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling and preparation reconstitution procedures to protect patients and health care workers from unintentional radiation exposure [





see





Dosage and Administration (2.1)]

5.2 Risk For Image Misinterpretation

The uptake of Ga 68 dotatate reflects the level of somatostatin receptor density in NETs. However, uptake can also be seen in a variety of other tumor types (e.g. those derived from neural crest tissue). Increased uptake might also be seen in other pathologic conditions (e.g. thyroid disease or subacute inflammation) or might occur as a normal physiologic variant (e.g. uncinate process of the pancreas). The uptake may need to be confirmed by histopathology or other assessments [see






Image Interpretation (2.7)
] .

6.1 Clinical Trial Experience

The safety of Ga 68 dotatate was evaluated in three single center studies


[see


Clinical Studies (14)]


and in a survey of the scientific literature. No serious adverse reactions were identified.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post-approval use of NETSPOT. 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 the drug.Gastrointestinal Disorders: Nausea and vomiting
General Disorders and Administration Site Conditions: Injection site pain and burning sensation

7 Drug Interactions

Non-radioactive somatostatin analogs competitively bind to the same somatostatin receptors as Ga 68 dotatate. Image patients with Ga 68 dotatate PET just prior to dosing with long-acting analogs of somatostatin. Short-acting analogs of somatostatin can be used up to 24 hours before imaging with Ga 68 dotatate.

8.1 Pregnancy

Risk SummaryThere are no studies with Ga 68 dotatate in pregnant women to inform any drug-associated risks; however, all radiopharmaceuticals, including Ga 68 dotatate have the potential to cause fetal harm. Animal reproduction studies have not been conducted with Ga 68 dotatate.In the U.S general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively.

8.2 Lactation

Risk SummaryThere is no information on the presence of Ga 68 dotatate in human milk, the effect on the breastfed infant, or the effect on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Ga 68 dotatate injection and any potential adverse effects on the breastfed child from Ga 68 dotatate injection or from the underlying maternal condition.Clinical ConsiderationsAdvise a lactating woman to interrupt breastfeeding and pump and discard breast milk for 12 hours after Ga 68 dotatate administration in order to minimize radiation exposure to a breastfed infant.

8.4 Pediatric Use

The efficacy of Ga 68 dotatate PET imaging in pediatric patients with neuroendocrine tumors is based on extrapolation from adult studies, from studies demonstrating the ability of Ga 68 dotatate to bind to somatostatin receptors [see






Clinical Pharmacology (12.1)
], and from a published study of Ga 68 dotatate PET imaging in pediatric patients with somatostatin receptor positive tumors. The safety profile of Ga 68 dotatate is similar in adult and pediatric patients with somatostatin receptor positive tumors. The recommended Ga 68 dotatate injection dose in pediatric patients is weight based as in adults [see






Dosage and Administration (2.2)
].

8.5 Geriatric Use

Clinical studies of Ga 68 dotatate injection did not include sufficient numbers of subjects aged 65 and over, to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

10 Overdosage

In the event of a radiation overdose, the absorbed dose to the patient should be reduced where possible by increasing the elimination of the radionuclide from the body by reinforced hydration and frequent bladder voiding. A diuretic might also be considered. If possible, an estimate of the radioactive dose given to the patient should be performed.

11 Description

  • NETSPOT is supplied as a sterile, single-dose kit for preparation of Ga 68 dotatate injection for intravenous use.Dotatate, also known as
  • DOTA-0-Tyr3-Octreotate, is a cyclic 8 amino acid peptide with a covalently bound chelator (dota). The peptide has the amino acid sequence: H-D-Phe-Cys-Tyr-D-Trp-Lys-Thr-Cys-Thr-OH, and contains one disulfide bond. Dotatate has a molecular weight of 1435.6 Daltons and its chemical structure is shown in Figure 2 .

12.1 Mechanism Of Action

Ga 68 dotatate binds to somatostatin receptors, with highest affinity for subtype 2 receptors (sstr2).  It binds to cells that express somatostatin receptors including malignant cells, which overexpress sstr2 receptors. Gallium 68 (





68Ga) is a β+ emitting radionuclide with an emission yield that allows positron emission tomography (PET) imaging.

12.2 Pharmacodynamics

The relationship between Ga 68 dotatate plasma concentrations and successful imaging was not explored in clinical trials.

12.3 Pharmacokinetics

DistributionGa 68 dotatate distributes to all sstr2-expressing organs such as pituitary, thyroid, spleen, adrenals, kidney, pancreas, prostate, liver, and salivary glands





. There is no uptake in the cerebral cortex or in the heart, and usually thymus and lung uptakes are low.





EliminationA total of 12% of the injected dose is excreted in urine in the first four hours post-injection.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

No animal studies on fertility, embryology, mutagenic potential, or carcinogenic potential have been conducted with Ga 68 dotatate. However, genotoxicity studies conducted with a very similar molecule (mixture Lu 175 dotatate/dotatate) shows that these non-radioactive compounds do not induce mutation at the TK locus of L5178Y mouse lymphoma cells in vitro, nor reverse mutation in





Salmonella typhimurium, or





Escherichia coli (both in the absence or presence of S9 metabolic activation).

14 Clinical Studies

The efficacy of NETSPOT was established in three open label single center studies (Study A-C).In Study A, 97 adult patients (mean age 54; 41men and 56 women) with known or suspected neuroendocrine tumors (NETs) were evaluated with Ga 68 dotatate PET. The Ga 68 dotatate images were read by two independent readers blinded to clinical information. The reads were compared to CT and/or MR images and to indium In 111 pentetreotide images obtained with Single Photon Emission Computed Tomography (SPECT) within previous 3 years. Among 78 patients in whom CT and/or MR images and In 111 pentetreotide images were available, Ga 68 dotatate PET was in agreement with the CT and/or MR images in 74 patients. Out of 50 patients with NETs localized by CT and/or MR imaging, Ga 68 dotatate was positive in 48 patients including 13 patients in whom In 111 pentetreotide was negative. Ga 68 dotatate was negative in 26 out of 28 patients in whom CT and/or MR imaging was negative.Study B was a published study which involved 104 patients (mean age 58; 52 men and 52 women) with suspected NETs due to clinical symptoms, elevated levels of tumor markers, or indeterminate tumors suggestive of NET. Diagnostic performance of Ga 68 dotatate PET in localizing tumor sites was retrospectively assessed using a reference standard: histopathology (n=49) or clinical follow up of up to 5 month duration (n=55). Images were interpreted by consensus between two on-site readers who were not blinded to clinical information. NET sites were localized by reference standard in 36 patients (all by histopathology). Out of these, Ga 68 dotatate was positive, correctly identifying an NET site, in





29 patients and was falsely negative in seven. In 68 patients with no NET identified by a reference standard, the images were negative in 61 and falsely positive in seven patients.





Study C was a published study which involved 63 patients (mean age 58; 34 men and 29 women) evaluated for NET recurrence using a reference standard as described for Study B.





Ga 68 dotatate images were interpreted independently by two central readers blinded to clinical information. Reader 1 correctly localized NETs in 23 out of 29 reference standard-positive patients and reader 2 correctly localized NETs in 22 such patients. In 34 patients with no NET identified by a reference standard, reader 1 was correct in 29 patients and reader 2 in 32.
