white to off-white or pale yellow
clear, colourless solution
This medicinal product is for diagnostic use only.
Hexvix blue light fluorescence cystoscopy is indicated as adjunct to standard white
light cystoscopy to contribute to the diagnosis and management of bladder cancer in
patients with known or high suspicion of bladder cancer. See section 5.1.
Posology and method of administration
Hexvix cystoscopy should only be performed by healthcare professionals trained specifically
in Hexvix cystoscopy. The bladder should be drained before the instillation.
Adults (including the elderly)
50 ml of 8 mmol/l reconstituted solution (see section 6.6) is instilled into the bladder through
a catheter. The patient should retain the fluid for approximately 60 minutes.
Following evacuation of the bladder, the cystoscopic examination in blue light should start
within approximately 60 minutes. The cystoscopic examination should not be performed more
than 3 hours after Hexvix is instilled in the bladder.
Also if the retention time in the bladder is considerably shorter than one hour, examination
should start no earlier than after 60 minutes. No minimum retention time has been identified
making examination non-informative.
For optimal visualisation it is recommended to examine and map the entire bladder under both
white and blue light before any surgical measures are initiated. Biopsies of all mapped lesions
should normally be taken under white light and complete resection should be verified by
switching to blue light.
Only CE marked cystoscopic equipment should be used, equipped with necessary filters to
allow both standard white light cystoscopy and blue light (wavelength 380–450 nm)
The light doses given during cystoscopy will vary. Typical total light doses (white light and
blue light) range between 180 and 360 J at an intensity of 0.25 mW/cm2.
Children and adolescents
There is no experience of treating patients below the age of 18 years.
Method of administration
Precaution to be taken before handling or administrating the medicinal product.
For instructions on reconstitution of the medicinal product before administration, see section
Hypersensitivity to the active substance or to any of the excipients listed in
Special warnings and precautions for use
The possibility of hypersensitivity including serious anaphylactic/anaphylactoid
reactions should always be considered (see section 4.8). Advanced life support
facilities should be readily available.
Post-marketing experience with repeated use of Hexvix does not indicate that it
represents a risk when used in follow-up in patients with bladder cancer, however no
specific studies have been conducted.
Hexaminolevulinate should not be used in patients at high risk of bladder
inflammation, e.g. after BCG therapy, or in moderate to severe leucocytouria.
Widespread inflammation of the bladder should be excluded by cystoscopy before the
product is administered. Inflammation may lead to increased porphyrin build up and
increased risk of local toxicity upon illumination, and false fluorescence.
If a wide-spread inflammation in the bladder becomes evident during white light
inspection, the blue light inspection should be avoided.
There is an increased risk of false fluorescence in the resection area in patients who
recently have undergone surgical procedures of the bladder
Interaction with other medicinal products and other forms of interaction
No specific interaction studies have been performed with hexaminolevulinate.
Fertility, pregnancy and lactation
There are no or limited data on the use of hexaminolevulinate in pregnant women.
Animal studies do not indicate direct or indirect harmful effects with respect to the
reproductive toxicity (see section 5.3). As a precautionary measure, it is preferable to
avoid the use of Hexvix during pregnancy.
It is unknown whether hexaminolevulinate/metabolites are excreted in human milk. A
risk to the newborns/infants cannot be excluded. Breast-feeding should be
discontinued during the treatment with Hexvix.
Animal studies do not indicate effects on female fertility (see section 5.3). Male
fertility has not been investigated in animals.
Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been
Most of the reported adverse reactions were transient and mild or moderate in intensity. The
most frequently reported adverse reactions from clinical studies were bladder spasm, reported
by 2.4 % of the patients, dysuria by 1.8%, bladder pain by 1.7 % and haematuria by 1.7%, of
the patients. The adverse reactions that were observed were expected, based on previous
experience with standard cystoscopy and transurethral resection of the bladder (TURB)

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal product.
Healthcare professionals are asked to report any suspected adverse reactions via the Yellow
Card Scheme at: www.mhra.gov.uk/yellowcard
No case of overdose has been reported.
No adverse events have been reported with prolonged instillation times
exceeding 180 minutes (3 times the recommended instillation time), in one
case 343 minutes. No adverse events have been reported in the dose-finding
studies using twice the recommended concentration of hexaminolevulinate.
There is no experience of higher light intensity than recommended or
prolonged light exposure.
Pharmacotherapeutic group: Other diagnostic agents, ATC code: V04CX
In vitro studies have shown a considerable build-up of porphyrin fluorescence in
malignant urothelium after exposure to hexaminolevulinate.
In humans, a higher degree of accumulation of porphyrins in lesions compared to
normal bladder urothelium has been demonstrated with Hexvix. After instillation of
the reconstituted solution for 1 hour and subsequent illumination with blue light,
tumours can be readily visualized by fluorescence.
Clinical studies using Hexvix included 1072 evaluable patients with known bladder
cancer or high suspicion of bladder cancer, who underwent white light, followed by
blue light cystoscopy, and biopsies.
In the clinical studies, the patients had known or suspected bladder cancer by
cystoscopy or positive urine cytology.
In studies in patients with increased risk of CIS, significantly more CIS and papillary
lesions were detected after blue light cystoscopies, as compared to standard white
light cystoscopy. The detection rate for CIS was 49.5% for standard white light
cystoscopy and 95.0% for blue light cystoscopy, and the detection rate for papillary
lesions ranged between 85.4% and 94.3% for white light and between 90.6% and
100% for blue light cystoscopy.
One of the above studies was designed to investigate the influence of patient
management according to the European Association of Urology Recommendations on
treatment of superficial bladder cancer. In 17% of patients, findings after blue light
cystoscopy led to more complete therapy, and in 5.5% of patients less complete
therapy was identified using only blue light cystoscopy. Reasons for more complete
therapy was improved tumour detection compared to standard cystoscopy, and
included more pTa lesions (20% of the patients), more CIS lesions (14%), and more
pT1 lesions (11%) only detected with Hexvix cystoscopy.
A randomized, white light only comparative study was undertaken in patients with
papillary tumors and increased risk of recurrence. A within patient comparison
showed that a total of 16.4% (47/286) of patients with pTa/pT1 lesions had additional
such lesions detected with Hexvix blue light cystoscopy only. Patients with pTa/pT1
lesions were followed for 9 months after cystoscopy, and the proportion of patients
with recurrence was lower in the Hexvix group (47%, 128/271) than in the white light
only cystoscopy group (56.1%, 157/280) in the ITT population, where all patients
with missing data were assumed to have recurrence. The number of patients with
missing data in the study was too high (56/128 and 59/157, in the Hexvix and control
groups respectively) for the difference to be considered statistically robust (p=0.030.06 pending on ways to handle missing data). Further follow-up information was
obtained for 86% of the participants. Median follow-up in the white light only and
Hexvix groups were 53 and 55 months, respectively. The patients in the Hexvix group
had a median of 7 months longer time to recurrence and recurrence-free survival (16
months in the Hexvix group versus 9 months in the white light group, p=0.04-0.06,
pending on handling of missing data and deaths).
The overall rate of finding false positive lesions was increased after blue light
cystoscopy, 17.3% for white light cystoscopy and 21.9% for blue light cystoscopy.
Mechanism of Action:
After intravesical instillation of hexaminolevulinate, porphyrins will accumulate
intracellularly in bladder wall lesions. The intracellular porphyrins (including PpIX)
are photoactive, fluorescing compounds which emit red light upon blue light
excitation. As a result, premalignant and malignant lesions will glow red on a blue
background. False fluorescence may be seen as a result of inflammation.
In vivo autoradiography studies in rats after intravesical administration have
shown high concentrations of hexaminolevulinate in the bladder wall.
After intravesical instillation of radiolabelled hexaminolevulinate in healthy
volunteers, the systemic bioavailability of total radioactivity was
Preclinical safety data
Studies in rats and dogs have not indicated any risks for systemic toxicity.
Seven-day intravesical tolerance studies, without light exposure, were performed in
rats and dogs. The study in rats showed cases of leukocytosis, suggesting a
proinflammatory activity of hexaminolevulinate. Cases of azotemia, red coloured
urine and weight loss were also seen. In dogs treated with hexaminolevulinate there
was a marginally increased incidence and severity of transition cell hyperplasia and
basophilia in the urinary epithelium.
A local lymph node assay in mice has demonstrated that hexaminolevulinate has a
potential to cause skin sensitisation.
Potential genotoxicity has been investigated in vitro in procaryotic and eucaryotic
cells in the presence and absence of photoactivating illumination and in vivo. All the
studies of genotoxic potential were negative (Ames test, TK assay, in vivo
micronucleus cell model, chromosome aberrations in CHO cells, and Comet assay on
vesical samples from a dog local tolerance study with blue light activation).
Reproductive toxicity has been investigated in rats and rabbits. The incidences of
embryo-fetal mortality, fetal weights, and the fetal abnormalities and variants,
including skeletal ossification parameters did not indicate any obvious effect of
treatment. There were no effects on female fertility and on early embryonic
development when investigated in rats.
Carcinogenicity studies have not been performed with hexaminolevulinate.
