5 Warnings and Precautions

5.2 Failed Detection

Additions and/or revisions underlined:

…

The presence of urine and/or blood within the bladder may interfere with the detection of tissue fluorescence. To enhance the diagnostic utility of CYSVIEW:


      • Ensure the bladder is emptied of urine prior to the instillation of fluids at cystoscopy.

      • Rinse the bladder as needed during cystoscopy to optimize visualisation.

      • Biopsy/resect bladder mucosal lesions only following completion of both white light and blue light rigid cystoscopy.

 5.3 False Positive Fluorescence

Additions and/or revisions underlined:

Fluorescent areas detected during blue light cystoscopy may not indicate a bladder mucosal lesion. In clinical studies, approximately 20% of the lesions detected only by blue light cystoscopy showed neither dysplasia nor carcinoma [see Clinical Studies (14)]. False positive fluorescence may result from inflammation, cystoscopic trauma, and scar tissue from bladder mucosal biopsy from a previous cystoscopic examination, or following intravesical treatment such as recent BCG immunotherapy or intravesical chemotherapy. In a study of patients treated with recent BCG immunotherapy or intravesical chemotherapy, the rate of false positives with blue light was55% between 6 weeks to 90 days and 41% after 90 days; the false positive rate was 53% and 33% at the respective time intervals with white light.

6 Adverse Reactions

Additions and/or revisions underlined:

The following clinically significant adverse reaction is discussed elsewhere in the Prescribing Information:

  • Anaphylaxis [see Warnings and Precautions (5.1)].

 6.1 Clinical Trials Experience

Subsection title revised

Additions and/or revisions underlined:

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 CYSVIEW was evaluated in 1,628 patients in seven clinical trials. Patients were aged 32 to 96 years with a median age of 70 years, 77% male, 88% White, 3% Black or African American, and 9% of unspecified racial group. All patients were evaluated after a single instillation of 100 mg of CYSVIEW, and 103 patients received a repeat administration of CYSVIEW [see Clinical Studies (14)].

The most common adverse reaction was bladder spasm (reported in 2% of the patients) followed by dysuria, hematuria, and bladder pain.

8 Use in Specific Populations

8.5 Geriatric Use

Additions and/or revisions underlined:

Of 2,127 subjects in clinical studies of CYSVIEW, 67% were 65 years and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Anaphylaxis

Inform patients that CYSVIEW may cause severe hypersensitivity reactions including anaphylactic shock. Instruct patients to seek immediate medical attention if they experience any symptoms of hypersensitivity reactions [see Warnings and Precautions (5.1)].

Administration Instructions

Inform patients that CYSVIEW should be retained in the bladder for at least 1 hour from instillation of CYSVIEW to the start of the cystoscopic procedure. If the patient cannot hold CYSVIEW for 1 hour and needs to void and expel CYSVIEW from the bladder, they may void and should then inform a healthcare professional [see Dosage and Administration (2.5)].

5 Warnings and Precautions

5.3 False Positive Fluorescence

(additions underlined)

Fluorescent areas detected during blue light cystoscopy may not indicate a bladder mucosal lesion. In the controlled clinical studies, approximately 20% of the lesions detected only by blue light cystoscopy showed neither dysplasia nor carcinoma.Fulse positive fluorescence may result from inflammation, cystoscopic trauma, scar tissue or bladder mucosal biopsy from a previous cystoscopic examination, and recent BCG immunotherapy or intravesical chemotherapy. In a study of patients treated with recent BCG immunotherapy or intravesical chemotherapy, the rate of false positives with blue light was 55% between 6 weeks to 90 days and 41% after 90 days; the false positive rate was 53% and 33% at the respective time intervals with white light.

The presence of urine and/or blood within the bladder may interfere with the detection of tissue fluorescence. To enhance the diagnostic utility of Cysview with the KARL STORZ D-Light C PDD System:

  • ensure the bladder is emptied of urine prior to the instillation of fluids at cystoscopy;

  • biopsy/resect bladder mucosal lesions only following completion of both white light and blue light rigid cystoscopy;

6 Adverse Reactions

6.1 Clinical Study Experience

(additions underlined)

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.

In seven clinical trials, safety data were obtained from 1,628 patients, aged 32 to 96 years with a median age of 70 years, all primarily Caucasian and approximately 75% male. All patients were evaluated after a single instillation of 50 mL solution of Cysview, and 103 patients received a repeat administration of Cysview. Of these patients, 170 (10.4%) patients reported at least one adverse reaction.

The most common adverse reaction was bladder spasm (reported in 2.0% of the patients) followed by dysuria, hematuria, and bladder pain. No patients experienced anaphylaxis. In the randomized controlled clinical study, adverse reactions were similar in nature and rate between the study drug group and the control group. In a controlled study using Cysview in the surveillance setting, adverse reaction types were similar.

8 Use in Specific Populations

8.1 Pregnancy

(PLLR conversion)

Risk Summary

There are no available data on Cysview use in pregnant women to inform a drug associated risk of adverse developmental outcomes. Adequate reproductive and developmental toxicity studies in animals have not been performed. Systemic absorption following administration of Cysview is expected to be minimal.

The background risk of major birth defects and miscarriage for the indicated populations 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 2-4% and 15-20%, respectively.

8.2 Lactation

(PLLR conversion)

Risk Summary

There are no data on the presence of hexaminolevulinate in human or animal milk, the effects on a breastfed infant, or the effects on milk production. Systemic absorption following administration of Cysview is expected to be minimal.The lack of clinical data during lactation precludes a clear determination of the risk of Cysview to an infant during lactation;

therefore, the development and health benefits of breastfeeding should be considered along with the mother’s clinical need for Cysview and any potential adverse effects on the breastfed infant from Cysview or from the underlying maternal condition.
