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.

Adverse Reactions

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

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.

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)].

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;

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.

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.
