PYLARIFY PET/CT Case Studies

In 2 patients with similar clinical presentation, PYLARIFY® PET/CT reveals each patient's unique extent of disease¹

CASE 1: 73-YEAR-OLD MAN

BCR after radical prostatectomy and lymph node dissection pT2N0M0 | Gleason 3+4 | PSA: 0.8 ng/mL

with BCR in peri-rectal lymph node

Figure A

Anterior whole body PYLARIFY® PET MIP shows uptake in the right peri-rectal lymph node (blue arrow; Fig A).

BCR treated with SBRT

Before PYLARIFY®, the recommended treatment was EBRT to the pelvis with an additional boost to the prostatic fossa
Based on the results of PYLARIFY® PET/CT, the patient received SBRT to the lesion
- Post treatment, PSA levels decreased to 0.06 ng/mL

CASE 2: 79-YEAR-OLD MAN

BCR after radical prostatectomy | pT2bN0M0
Gleason 3+4 | PSA: 0.9 ng/mL

with BCR in cervical and supraclavicular lymph nodes

Figure B

Anterior whole body PYLARIFY® PET MIP shows uptake in multiple left lower cervical and supraclavicular lymph nodes (blue arrow; Fig B).

with BCR treated with IMRT

Lymph nodes treated with IMRT and patient was started on ADT
PSA decreased to 0.04 ng/mL 1 month after radiation
Follow-up imaging showed no evidence of metastatic disease

In CONDOR, across the 3 readers, PYLARIFY® detected at least 1 previously occult lesion in 59.6%-65.9% of patients^2,3

Diagnostic images from the Condor Trial showing abdominal lesions in the human body

PYLARIFY® PET scan revealing that a 71-year-old patient had left common iliac lesions and multiple lymph node lesions

71-year-old patient had a Gleason score of 4+3, history of radical prostatectomy, EBRT with PSA 1.92 ng/mL, and equivocal results on ¹⁸F fluciclovine PET/CT scan
PYLARIFY® showed left common iliac lesions and multiple retroperitoneal para/peri aortic lymph node lesions
Biopsy of retroperitoneal lymph node confirmed prostate cancer

Efficacy and Safety How to Use PYLARIFY

INDICATION & IMPORTANT
SAFETY INFORMATION

PYLARIFY® (piflufolastat F 18) Injection is a radioactive diagnostic agent indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer:

with suspected metastasis who are candidates for initial definitive therapy.

with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level.

Radiation Risks

Diagnostic radiopharmaceuticals, including PYLARIFY, expose patients to radiation. 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.

INDICATION

with suspected metastasis who are candidates for initial definitive therapy.

with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level.

INDICATION

with suspected metastasis who are candidates for initial definitive therapy.
with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level.

IMPORTANT SAFETY INFORMATION

Contraindications

None.

Warnings and Precautions

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. 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. 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.

Hypersensitivity Reactions

Monitor patients for hypersensitivity reactions, particularly patients with a history of allergy to other drugs and foods. Reactions may be delayed. Always have trained staff and resuscitation equipment available.

Radiation Risks

Adverse Reactions

The most frequently reported adverse reactions were headaches, dysgeusia and fatigue, occurring at rate of ≤2% during clinical studies with PYLARIFY. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reactions.

Drug Interactions

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.

To report suspected adverse reactions for PYLARIFY, call 1-800-362-26681-80‌0-36‌2-2668 or contact FDA at 1-800-332-10881-800-FDA-1088 or www.fda.gov/medwatch.
