5.2 Failed Detection
Cysview may fail to detect some bladder tumors, including malignant lesions. Cysview is not a replacement for random biopsies or any other procedure usually performed in the cystoscopic evaluation for cancer. In the controlled clinical trial, Cysview failed to detect 10% of lesions confirmed as malignant within the study drug group [see CLINICAL STUDIES (14)]. Do not perform cystoscopy with blue light alone as malignant lesions can be missed unless the bladder is initially examined under white light [see DOSAGE AND ADMINISTRATION (2.5)].

5.3 False Fluorescence
Fluorescent areas detected during blue light cystoscopy may not indicate a bladder mucosal lesion. In the controlled clinical study, biopsies from one of every four fluorescent areas showed neither dysplasia nor carcinoma, if the areas were not also identified during white light cystoscopy [see CLINICAL STUDIES (14)]. In addition to these false detections, fluorescent areas within the bladder mucosa may result from inflammation, cystoscopic trauma, scar tissue or bladder mucosal biopsy from a previous cystoscopic examination.

Overview

Hexaminolevulinate is a Diagnostic Agent that is FDA approved for the diagnosis of cystoscopic detection of non-muscle invasive papillary cancer of the bladder. Common adverse reactions include Bladder pain, Dysuria, Hematuria, Spasm of bladder.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Indications

Cysview is an optical imaging agent indicated for use in the cystoscopic detection of non-muscle invasive papillary cancer of the bladder among patients suspected or known to have lesion(s) on the basis of a prior cystoscopy. Cysview is used with the Karl Storz D-Light C Photodynamic Diagnostic (PDD) system to perform cystoscopy with the blue light setting (Mode 2) as an adjunct to the white light setting (Mode 1).

1.1 Limitations of Use Cysview is not:

a replacement for random bladder biopsies or other procedures used in the detection of bladder cancer [see WARNINGS AND PRECAUTIONS (5.2)]. for repetitive use. The potential risks associated with repetitive exposure, including sensitization and adverse effects of blue light have not been evaluated

Dosage

2.1 Recommended Dose The recommended dose for adults is 50 mL of reconstituted solution of Cysview [see DOSAGE AND ADMINISTRATION (2.2)], instilled into the bladder via a urinary catheter [see DOSAGE AND ADMINISTRATION (2.3)].

2.2 Reconstitution of Cysview Cysview is supplied as a kit containing two vials: a clear glass vial labeled as Cysview (hexaminolevulinate hydrochloride) for Intravesical Solution, containing 100 mg hexaminolevulinate hydrochloride as a powder, and a vial labeled as DILUENT for Cysview, containing 50 mL of the diluent in a polypropylene vial.

Perform all steps under aseptic conditions. Use gloves during the reconstitution procedure; skin exposure to hexaminolevulinate hydrochloride may increase the risk for sensitization to the drug.

Use a 50 mL syringe with a Luer Lock tip throughout the reconstitution procedure to ensure that the correct concentration (2mg/mL) of the drug is obtained and that a stable syringe-catheter connection is made for the bladder instillation of Cysview.

2.3 Bladder Instillation of Cysview For bladder instillation of the solution of Cysview, use straight, or intermittent, urethral catheters with a proximal funnel opening that will accommodate the Luer Lock adapter. Use only catheters made of vinyl (uncoated or coated with hydrogel), latex (amber or red), and silicone to instill the reconstituted Cysview. Do not use catheters coated or embedded with silver or antibiotics. In-dwelling bladder catheters (Foley catheters) may be used if the catheters are inserted shortly prior to Cysview administration and are removed following the Cysview instillation.

Use the following steps for bladder instillation of Cysview:

Using standard sterile catheterization technique, first insert the urethral catheter into the bladder of the patient and use the catheter to completely empty the patient's bladder before instillation of Cysview.

Avoid skin contact with Cysview. If skin does come in contact with Cysview, wash immediately with soap and water and dry off. After voiding the bladder of Cysview, routinely wash the patient's perineal skin region with soap and water and dry.

2.4 Use of the Karl Storz D-Light C Photodynamic Diagnostic (PDD) System Cysview imaging requires the use of the Karl Storz D-Light C PDD system, which consists of a light source, a camera and a telescope. The light source enables both white light cystoscopy and blue light (wavelength 360 – 450 nm) fluorescence cystoscopy. Familiarity with this system is essential before beginning the procedure and before instilling Cysview into the bladder. For system set up and general information for the safe use of the PDD system, refer to the Karl Storz instruction manual for the PDD system and the instruction manuals for each of the system components. The PDD System is not for use by healthcare providers with green-red color blindness.

2.5 Cystoscopic Examination Training

Training and proficiency in cystoscopic procedures are essential prior to the use of Cysview. Carefully review the instruction manuals provided with the Karl Storz D-Light C Photodynamic Diagnosis (PDD) System. For additional training in the use of the PDD System, contact the manufacturer's representative.

Preparation for Cystoscopy

Initiate the cystoscopic examination within 30 minutes after evacuation of Cysview from the bladder, but no less than 1 or more than 3 hours after Cysview is instilled in the bladder. If the patient did not retain Cysview in the bladder for 1 hour, allow 1 hour to pass from the instillation of Cysview into the bladder to the start of the cystoscopic examination. The efficacy of Cysview has not been established when the solution was retained for less than 1 hour.

Cystoscopic Examination

Empty the patient's bladder and then fill the bladder with a clear fluid (standard bladder irrigation fluid) in order to distend the bladder wall for cystoscopic visibility. Ensure adequate irrigation during examination of the bladder; blood, urine or floating particles in the bladder may interfere with visualization under both white light and blue light.

First perform a complete cystoscopic examination of the entire bladder under white light (Mode 1) and then repeat the examination of the entire bladder surface under blue light (Mode 2) unless the white light cystoscopy reveals extensive mucosal inflammation. Do not perform the blue light cystoscopy if the white light cystoscopy reveals wide-spread mucosal inflammation. Abnormalities of the bladder mucosa during blue light cystoscopy are characterized by the detection of red, homogenous and intense fluorescence. The margins of the abnormal lesions are typically well-demarcated and in contrast to the normal urothelium, which appears blue. Register and document (map) the location and appearance (e.g. papillary) of suspicious lesions and abnormalities seen under either white or blue light.

During the cystoscopic examination, be aware that:

a red fluorescence is expected at the bladder outlet and the prostatic urethra; this fluorescence occurs in normal tissue and is usually less intense and more diffuse than the bladder mucosal fluorescence associated with malignant lesions. tangential light may give false fluorescence. To help avoid false fluorescence, hold the endoscope perpendicular and close to the bladder wall with the bladder distended. false positive fluorescence may result from scope trauma from a previous cystoscopic examination and/or bladder inflammation [see WARNINGS AND PRECAUTIONS (5.3)]. malignant lesions may not fluoresce following Cysview administration, particularly if the lesions are coated with necrotic tissue. Blue light may fail to detect T2 tumors which have a tendency to be necrotic on the surface, and necrotic cells generally do not fluoresce [see WARNINGS AND PRECAUTIONS (5.3)]. when performing the blue light cystocopy, avoid prolonged blue light exposure. Studies have not evaluated the potential for adverse effects from blue light. In the controlled clinical trial, the cumulative blue light exposure from bladder mapping did not exceed 12 minutes and checking for complete tumor resection under blue light did not exceed 8 minutes for any patient [see CLINICAL STUDIES (14)]. Perform biopsy and/or resection of suspicious lesions by transurethral resection of the bladder (TURB) only after completing white and blue light cystoscopic examinations with bladder mapping. Using standard cystoscopic practices, obtain biopsies of abnormal areas identified during either white or blue light examination and perform resections. Always check for the completeness of the resections under both white light and blue light before finalizing the TURB procedure.

Contraindications

  • Cysview is contraindicated in patients with:

porphyria gross hematuria BCG immunotherapy or intravesical chemotherapy within the past 90 days known hypersensitivity to hexaminolevulinate or any derivative of aminolevulinic acid

Warnings

  • 5.1 Anaphylaxis

Anaphylaxis, including anaphylactoid shock, has been reported following administration of Cysview [see ADVERSE REACTIONS (6.2)]. Prior to and during use of the Cysview, have trained personnel and therapies available for the treatment of anaphylaxis. The safety of repetitive Cysview exposures has not been evaluated.

5.2 Failed Detection Cysview may fail to detect some bladder tumors, including malignant lesions. Cysview is not a replacement for random biopsies or any other procedure usually performed in the cystoscopic evaluation for cancer. In the controlled clinical trial, Cysview failed to detect 10% of lesions confirmed as malignant within the study drug group [see CLINICAL STUDIES (14)]. Do not perform cystoscopy with blue light alone as malignant lesions can be missed unless the bladder is initially examined under white light [see DOSAGE AND ADMINISTRATION (2.5)].

5.3 False Fluorescence Fluorescent areas detected during blue light cystoscopy may not indicate a bladder mucosal lesion. In the controlled clinical study, biopsies from one of every four fluorescent areas showed neither dysplasia nor carcinoma, if the areas were not also identified during white light cystoscopy [see CLINICAL STUDIES (14)]. In addition to these false detections, fluorescent areas within the bladder mucosa may result from inflammation, cystoscopic trauma, scar tissue or bladder mucosal biopsy from a previous cystoscopic examination.

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 cystoscopy;
