What is Pylarify?
From the FDA label:11.1 Chemical Characteristics PYLARIFY contains fluorine 18 (F 18), radiolabeled prostate-specific membrane antigen inhibitor imaging agent. Chemically piflufolastat F 18 is 2-(3-{1-carboxy-5-[(6-[18F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}ureido)-pentanedioic acid. The molecular weight is 441.4 and the structural formula is: The chiral purity of the unlabeled piflufolastat F 18 precursor is greater than 99% (S,S). PYLARIFY is a sterile, non-pyrogenic, clear, colorless solution for intravenous injection. Each milliliter contains 37 to 2,960 MBq (1 to 80 mCi) piflufolastat F 18 with ≤0.01 µg/mCi of piflufolastat at calibration time and date, and ≤ 78.9 mg ethanol in 0.9% sodium chloride injection USP. The pH of the solution is 4.5 to 7.0. PYLARIFY has a radiochemical purity of at least 95% up to 10 hours following end of synthesis, and specific activity of at least 1000 mCi/µmol at the time of administration. Chemical Structure 11.2 Physical Characteristics PYLARIFY is radiolabeled with fluorine 18 (F 18), a cyclotron produced radionuclide that decays by positron emission to stable oxygen 18 with a half-life of 109.8 minutes. The principal photons useful for diagnostic imaging are the coincident pair of 511 keV gamma photons, resulting from the interaction of the emitted positron with an electron (Table 3). Table 3. Principal Radiation Produced from Decay of Fluorine 18…
How to use
Recommended dose is 333 MBq (9 mCi) with an acceptable range of 296 MBq to 370 MBq (8 mCi to 10 mCi), administered as a bolus intravenous injection. ( 2.2 ) Initiate imaging approximately 60 minutes after PYLARIFY administration. The patient should void immediately prior to initiation of imaging. Image acquisition should start from mid-thigh and proceed to the skull vertex. ( 2.3 , 2.4 ) See full prescribing information for additional preparation, handling, administration, imaging, and radiation dosimetry information. ( 2 ) 2.1 Radiation Safety – Drug Handling PYLARIFY is a radioactive drug. Only authorized persons qualified by training and experience should receive, use, and administer PYLARIFY. Handle PYLARIFY with appropriate safety measures to minimize radiation exposure during administration [see Warnings and Precautions (5.3) ] . Use waterproof gloves and effective radiation shielding, including syringe shields, when preparing and handling PYLARIFY. 2.2 Recommended Dosage and Administration Instructions Recommended Dose The recommended amount of radioactivity to be administered for PET imaging is 333 MBq (9 mCi) with an acceptable range of 296 MBq to 370 MBq (8 mCi to 10 mCi) administered as a single bolus intravenous injection. Preparation and Administration Use aseptic technique and radiation shielding when preparing and administering PYLARIFY. Visually inspect the…
Side effects
The most common reported adverse reactions are headache, dysgeusia, and fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Progenics Pharmaceuticals, Inc. at 1-800-362-2668 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials 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 PYLARIFY was evaluated in 593 patients, each receiving one dose of PYLARIFY. The average injected activity was 340 ± 26 MBq (9.2 ± 0.7 mCi). The adverse reactions reported in >0.5% of patients within the studies are shown in Table 2. In addition, a hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reaction. Table 2. Adverse Reactions with a Frequency >0.5% in Patients Who Received PYLARIFY (n = 593) Adverse Reaction n (%) Headache 13 (2%) Dysgeusia 10 (2%) Fatigue 7 (1%)
Warnings
Important safety information
Risk of Image Misinterpretation : PYLARIFY uptake can be seen in a variety of tumor types as well as in non-malignant processes and normal tissues. Image interpretation errors can occur with PYLARIFY imaging. ( 5.1 ) Hypersensitivity Reactions : Monitor patients for hypersensitivity reactions, particularly patients with a history of allergy to other drugs and foods. ( 5.2 ) Radiation Risk : Ensure safe drug handling to protect patients and health care workers from unintentional radiation exposure. ( 5.3 ) 5.1 Risk of Image Misinterpretation Imaging interpretation errors can occur with PYLARIFY imaging. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of PYLARIFY for imaging of patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels [ see Clinical Studies (14) ]. The performance of PYLARIFY for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by risk factors such as Gleason score and tumor stage [ see Clinical Studies (14) ]. PYLARIFY uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes and in normal tissues. Clinical correlation, which may include histopathological evaluation of the suspected prostate cancer site, is recommended. 5.2 Hypersensitivity Reactions Monitor patients for hypersensitivity reactions, particularly patients with a history of allergy to other drugs and foods. Reactions may not be immediate. Always have trained staff and resuscitation equipment available. 5.3 Radiation Risks Diagnostic radiopharmaceuticals, including PYLARIFY, expose patients to radiation [see Dosage and Administration (2.6) ] . Radiation exposure is associated with a dose-dependent increased risk of cancer. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration [see Dosage and Administration (2.3) ] .
Who should not take Pylarify
None. None. ( 4 )
Overdose — what happens if you take too much
In the event of an overdose of PYLARIFY, reduce the radiation absorbed dose to the patient where possible by increasing the elimination of the drug from the body using hydration and frequent bladder voiding. A diuretic might also be considered. If possible, an estimate of the radiation effective dose administered to the patient should be made.
U.S. Poison Control: call or text 1-800-222-1222 (free, 24/7). In an emergency call 911. From the FDA label; not medical advice.
Interactions
Androgen deprivation therapy and other therapies targeting the androgen pathway Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of PYLARIFY in prostate cancer. The effect of these therapies on performance of PYLARIFY PET has not been established.
Storing Pylarify, and how long it keeps
Quoted from this product’s own FDA label. Storage belongs to the product and its device, not to the drug in general — a pen and a tablet of the same medicine are kept completely differently.
- “Store PYLARIFY in the original container with radiation shielding.”
