To report SUSPECTED ADVERSE REACTIONS, contact the UIHC – P E T Imaging Center at 1-319-356-1092 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch (6) 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Ga-68 DOTATOC injection was evaluated in 334 patients in clinical trials of patients receiving a single dose of Ga-68 DOTATOC injection for imaging known or suspected NET. The following adverse reactions occurred at a rate of < 2%: Gastrointestinal Disorders: nausea The following adverse reactions occurred at a rate of a < 1% Skin and Subcutaneous Tissue Disorders: pruritus Vascular Disorders: flushing 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of other somatostatin receptor imaging agents. 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. Immune System Disorders: Hypersensitivity reactions, predominantly rash, pruritus, less frequently angioedema or features of anaphylaxis

Edotreotide gallium GA-68 drug interactions

Quoted from the “Drug Interactions” section of the FDA-approved label. Tell your pharmacist about every medicine, vitamin and herbal product you take.

Non-radioactive somatostatin analogs bind to the same somatostatin receptors as Ga 68 DOTATOC Injection. Image patients with Ga 68 DOTATOC Injection 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 DOTATOC Injection [see Dosage and Administration (2.3)].

Edotreotide gallium GA-68 dosage

Quoted from the “Dosage and Administration” section of the FDA-approved label. Your own dose is the one your doctor prescribes: do not change it on your own.

Recommended dose for adults is 148 MBq (4 mCi) as a bolus intravenous injection (2.2) Recommended dose for pediatric patients is 1.59 MBq/kg (0.043 mCi/kg) with a range of 11.1 MBq (0.3 mCi) to 111 MBq (3 mCi), as a bolus intravenous injection (2.2) Initiate imaging 55 to 90 minutes after drug administration (2.4) See full prescribing information for additional preparation, administration, imaging and radiation dosimetry information (2) 2.1 Radiation Safety – Drug Handling Handle Ga 68 DOTATOC 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 DOTATOC 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. 2.2 Recommended Dosage and Administration Instructions Recommended Dosage In adults, the recommended amount of radioactivity to be administered for PET imaging is 4 mCi (148 MBq) with a range of 3 mCi to 5 mCi (111 MBq to 185 MBq) administered as an intravenous injection with an injection rate of approximately 10 seconds per mL. In pediatric patients, the recommended amount of radioactivity to be administered for PET imaging is 0.043 mCi/kg of body weight (1.59 MBq/kg) with a range of 0.3 mCi (11.1 MBq) to 3 mCi (111 MBq) as an intravenous injection with an injection rate of approximately 10 seconds per mL. Administration Use Ga 68 DOTATOC Injection within 3 hours of calibration time. Use aseptic technique and radiation shielding when withdrawing and administering Ga 68 DOTATOC Injection. Inspect Ga 68 DOTATOC Injection visually for particulate matter and discoloration before administration. Do not use the drug if the solution contains particulate matter or is discolored. Calculate the necessary volume to administer based on measured activity, volume, calibration time, and date. Measure the patient dose immediately prior to administration in a dose calibrator. After injection of Ga 68 DOTATOC Injection, administer an intravenous flush of sodium chloride injection, 0.9% to ensure full delivery of the dose. Dispose of any unused drug in a safe manner in compliance with applicable regulations. 2.3 Use with Somatostatin Analogs and Patient Hydration Somatostatin Analogs Somatostatin analogs bind to the same somatostatin receptors as Ga 68 DOTATOC Discontinue short-acting somatostatin analogs 24 hours before imaging with Ga 68 DOTATOC Injection. Image patients with Ga 68 DOTATOC Injection just prior to dosing with long-acting analogs of somatostatin [see Drug Interactions (7)]. Patient Hydration Instruct patients to drink water to ensure adequate hydration prior to administration of Ga 68 DOTATOC Injection and to continue to drink and void frequently during the first hours following administration to reduce radiation exposure [see Warnings and Precautions (5.1)]. 2.4 Image Acquisition For Ga 68 DOTATOC PET imaging, a whole-body acquisition from the skull vertex to mid-thigh is recommended.

Edotreotide gallium GA-68 in pregnancy

Quoted from the pregnancy part of the FDA-approved label. Ask your doctor before you take any medicine while pregnant or planning a pregnancy.

Risk Summary There are no available data on the use of Ga 68 DOTATOC Injection in pregnant women to identify a risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with Ga 68 DOTATOC. However, all radiopharmaceuticals, including Ga 68 DOTATOC Injection have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose.

If considering Ga 68 DOTATOC Injection administration to a pregnant woman, inform the patient of the potential for adverse pregnancy outcomes based on the radiation dose from Ga 68 DOTATOC Injection and the gestational timing of exposure. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.

Edotreotide gallium GA-68 overdose

Quoted from the “Overdosage” section of the FDA-approved label. If someone may have taken too much, call Poison Help at 1-800-222-1222 (or 911 in an emergency).

In the event of a radiation overdose, reduce the absorbed dose to the patient by increasing the elimination of the radionuclide from the body by reinforced hydration, frequent bladder voiding, and diuretics, if needed. If possible, perform an estimate of the radioactive dose given to the patient.
