All radiopharmaceuticals, including FLYRCADO, have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose. If considering FLYRCADO administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation dose from flurpiridaz F 18 and the gestational timing of exposure. FLYRCADO contains ethanol (a maximum daily dose of 337 mg anhydrous ethanol). The lower limit of safety for ethanol use during pregnancy has not been established. Published studies have demonstrated that ethanol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. If considering FLYRCADO administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes associated with ethanol exposure during pregnancy. The 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 risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively."],"description":["11 DESCRIPTION 11.1 Chemical Characteristics FLYRCADO (flurpiridaz F 18) injection is a radioactive diagnostic drug for intravenous use. The molecular formula of flurpiridaz F 18 is C 18 H 22 Cl 18 FN 2 O 3 , the molecular mass is 367.8, and the structural formula is: Chemically, flurpiridaz F 18 is 2- tert -butyl-4-chloro-5-[[4-(2-( 18 F)fluoranylethoxymethyl)phenyl]methoxy]pyridazin-3-one. FLYRCADO is a sterile, preservative-free, non-pyrogenic, clear, colorless to yellow radioactive solution. Each mL contains 190 MBq to 2,050 MBq (5 mCi to 55 mCi) of flurpiridaz F 18 at end of synthesis, up to 2.3 mcg flurpiridaz, and the following inactive ingredients: 45 mg hydroxypropyl-β-cyclodextrin (as a solubilizer and co-radiostabilizer), 35 mg L-(+)-ascorbic acid (as a radiostabilizer), 8.2 mg sodium hydroxide, and 55.2 mg anhydrous ethanol, in water for injection. The pH of the solution is between 5.5 and 8. Chemical Structure 11.2 Physical Characteristics Fluorine-18 decays by positron (β+) emission and has a half-life of 109.8 minutes. The principal photons useful for diagnostic imaging are the 511 keV gamma photons, resulting from the interaction of the emitted positron with an electron. Principal emission data for fluorine-18 are shown in Table 4. Table 4 – Principal Radiation Emission Data for Fluorine-18 Radiation/Emission % per Disintegration Mean Energy (keV) Positron 96.7 249.8 Gamma 193.5 511 11.3 External Radiation The point source air-kerma rate constant for fluorine-18 is 3.74E-17 Gy m 2 /(Bq s); this coefficient was formerly defined as the specific gamma-ray constant of 5.7 R/hr/mCi at 1 cm. The first half-value thickness of lead (Pb) for fluorine-18 gamma rays is approximately 6 mm. The relative reduction of radiation emitted by fluorine-18 that results from various thicknesses of lead shielding is shown in Table 5. The use of about 8 cm of Pb will decrease the radiation transmission (i.e., exposure) by a factor of about 10,000.

Subjects received two injections of FLYRCADO: one at rest and one during stress [see Dosage and Administration (2.2 , 2.3) ] . For the FLYRCADO stress injection, subjects received either a pharmacologic stress agent or engaged in exercise stress. PET myocardial perfusion imaging (MPI) was performed at both rest and stress using cardiac gating and low-dose CT attenuation correction. Subjects also received rest and stress SPECT MPI using technetium Tc 99m sestamibi or technetium Tc 99m tetrofosmin on a different day from the PET MPI. The stress modality was to be the same for PET and SPECT. Stress and rest images were displayed side-by-side for the assessment of perfusion and wall motion abnormalities. Three qualified readers, blinded to clinical data, performed independent assessment of each subject's rest and stress images, with each recording an overall qualitative diagnosis of normal, ischemia, ischemia plus scar, or scar. For analyses of sensitivity and specificity, normal was considered image negative and all other diagnoses were considered image positive. 14.2 Suspected Coronary Artery Disease Study 1 evaluated the sensitivity and specificity of FLYRCADO PET MPI for the detection of significant CAD in subjects with suspected CAD who were scheduled for invasive coronary angiography (ICA). A total of 578 subjects were evaluable for effectiveness, having rest and stress imaging and evaluable truth standard data. Subjects ranged in age from 26 years to 88 years, with a mean age of 64 years. A total of 188 (33%) were female, and 473 (82%) were White, 35 (6%) were Black or African American, 6 (1%) were Asian, and 64 (11%) were other races or not reported.

Table 1 – Recommended Administered Activities of FLYRCADO in Adults for Rest and Stress Imaging Using Pharmacologic or Exercise Stress in a 1-Day or 2-Day Protocol Length of Protocol Activity for Rest Imaging Activity for Stress Imaging Pharmacologic Exercise 1 day 93 MBq to 111 MBq (2.5 mCi to 3 mCi) 222 MBq to 241 MBq (6 mCi to 6.5 mCi) 333 MBq to 352 MBq (9 mCi to 9.5 mCi) 2 days 93 MBq to 111 MBq (2.5 mCi to 3 mCi) 93 MBq to 111 MBq (2.5 mCi to 3 mCi) 93 MBq to 111 MBq (2.5 mCi to 3 mCi) Patient Preparation Instruct patients to drink water to ensure adequate hydration prior to administration of FLYRCADO and to continue drinking and voiding frequently during the first hours following administration to reduce radiation exposure [see Warnings and Precautions (5.2) ] . Drug Preparation Use aseptic technique and radiation shielding to withdraw and administer FLYRCADO. Calculate the necessary volume to administer based on calibration time and activity using a suitably calibrated instrument. Visually inspect FLYRCADO for particulate matter and discoloration prior to administration and do not use if either is observed. Ensure the correct syringe is used and has adequate volume (at least 1 mL to 2 mL) so that the activity in the syringe can be administered without excessive dead volume loss. Measure patient dose using a dose calibrator immediately before administration. Do not use and discard FLYRCADO 8 hours after end of synthesis or when the activity falls below the activity requirement at the time of injection, whichever is earlier. FLYRCADO may be diluted aseptically with 0.9% Sodium Chloride Injection, USP. Diluted product should be used within 8 hours after end of synthesis or when the activity falls below the activity requirement at the time of injection, whichever is earlier. Dispose of unused product in a safe manner and in compliance with applicable regulations. Administration Instructions Administer FLYRCADO via intravenous injection as a bolus lasting less than 10 seconds and immediately follow with a flush of 0.9% Sodium Chloride Injection, USP. The minimum time between rest and stress dose administration is: 30 minutes when using pharmacologic stress 60 minutes when using exercise stress When using pharmacologic stress, administer FLYRCADO at the time of peak vasodilation according to the prescribing information for the stress agent, using an intravenous port different from the one used for the stress agent. When using exercise stress, administer FLYRCADO after the patient reaches at least 85% of their age-predicted maximum heart rate or exhibits ischemic signs or symptoms. The patient should then continue to exercise for approximately 1 minute to 2 minutes after the injection. If the patient cannot achieve the target heart rate, the examination may be converted to pharmacologic stress. 2.3 Image Acquisition Instructions For rest and stress imaging, image reconstruction should include attenuation correction. Rest Imaging Begin the PET acquisition 5 minutes after FLYRCADO administration and acquire images for 10 minutes using a scanner in 3D mode. Pharmacologic Stress Imaging Begin the PET acquisition 5 minutes after FLYRCADO administration and acquire images for 10 minutes using a scanner in 3D mode. Optionally, dynamic imaging may be performed, starting immediately prior to the injection of FLYRCADO. Exercise Stress Imaging Once the patient has been positioned on the scanner and respiration has begun to return to normal, begin image acquisition (about 15 minutes to 25 minutes after administration of FLYRCADO). Acquire images for 10 minutes using a scanner in 3D mode. 2.4 Radiation Dosimetry Table 2 shows the estimated radiation absorbed doses per unit of injected activity.

A lactating woman should pump and discard breastmilk for at least 8 hours after FLYRCADO administration. ( 8.2 ) 8.1 Pregnancy Risk Summary There are no data on use of flurpiridaz F 18 in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. All radiopharmaceuticals, including FLYRCADO, have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose. If considering FLYRCADO administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation dose from flurpiridaz F 18 and the gestational timing of exposure. FLYRCADO contains ethanol (a maximum daily dose of 337 mg anhydrous ethanol). The lower limit of safety for ethanol use during pregnancy has not been established. Published studies have demonstrated that ethanol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. If considering FLYRCADO administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes associated with ethanol exposure during pregnancy. The 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 risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. 8.2 Lactation Risk Summary There are no data on the presence of flurpiridaz F 18 or its metabolites in human milk or animal milk, the effects on the breastfed infant, or the effects on milk production. Based on clinical guidelines, exposure of FLYRCADO to a breastfed infant can be minimized by advising a lactating woman to temporarily discontinue breastfeeding and to pump and discard breast milk for a minimum of 8 hours after administration of FLYRCADO. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for FLYRCADO and any potential adverse effects on the breastfed child from FLYRCADO or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness of FLYRCADO in pediatric patients have not been established. 8.5 Geriatric Use Of 1,600 subjects in clinical studies of FLYRCADO, 720 (45%) were 65 years of age and over and 181 (11%) were 75 years of age or older. No overall differences in safety or effectiveness of FLYRCADO have been observed between patients 65 years of age and older and younger adult patients."],"dosage_and_administration_table":["
