About this trial

This is an interventional diagnostic trial for Bladder Cancer

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria: Volunteer to participate in clinical study; thoroughly informed, signed and dated the informed consent form; willing to follow and have the ability to complete all trial procedures. Suspicious or confirmed patients with bladder cancer. Age 18 or older. Exclusion Criteria: Gross haematuria. (Note: Gross haematuria is defined as a heavy bladder bleed resulting in marked amounts of blood in the urine, which may visually limit cystoscopy. Where the haematuria is light, the patient should not be excluded, if in the investigator's opinion, rinsing and/or electro-cautery during cystoscopy will alleviate the possible interference with cystoscopy). Patients who have received BCG immunotherapy or intravesical chemotherapy within the past 6 weeks prior to the procedure. Porphyria. Known allergy to hexaminolevulinate hydrochloride or a similar compound. Pregnancy or breast-feeding or women who plan to become pregnant during the trial, and men or women who are unwilling to take barrier contraceptives from 2 weeks before application of investigational medication to 28 days after application of investigational medication (Note: All women of child-bearing potential must document a negative urine pregnancy test before study inclusion and use adequate contraception during the study. Participation in other clinical studies with investigational drugs either concurrently or within the last 30 days. Patient is the investigator or any sub investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol. Patients that the investigator assessed unsuitable to the study. Subjects with contraindications to white light cystoscopy.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Hexvix Blue light cystoscopy

Arm Description

In this study, enrolled patients will undergo standard White light cystoscopy and Blue light cystoscopy following Hexvix administration. Lesions detected during the cystoscopies will be resected or biopsied.

Outcomes

Primary Outcome Measures

Proportion of patients with histology-confirmed lesions (Ta, T1, or CIS) who have at least one such lesion found by Hexvix blue light cystoscopy but not by white light cystoscopy.

Secondary Outcome Measures

Proportion of subjects with at least one additional CIS lesion detected with Hexvix blue light cystoscopy but not with white light cystoscopy.
The lesion detection rate of Hexvix blue light cystoscopy and white light cystoscopy for following lesion types (PUNLMP, CIS, Ta, T1, T2-T4).
The proportion of false positive lesions detected with Hexvix blue light cystoscopy and white light cystoscopy.

5. Study Description

Brief Summary
A study to compare Hexvix Blue light cstoscopy with standard White light cystoscopy in the detection of bladder cancer.
Detailed Description
A phase III, prospective, within patient controlled, multi-center study to compare Blue light cystoscopy with Hexvix and standard White light cystoscopy in the detection of bladder cancer, to evaluate the efficacy and safety of Hexvix Blue light cystoscopy in Chinese population. Patients with suspicious or confirmed bladder cancer will participate in the trial and undergo Blue light cystoscopy with Hexvix in addition to the standard White light cystoscopy. Specific clinical questions will be asked: What is the proportion of patients who have at least one specific kind of tumor found by Blue light cystoscopy with Hexvix but not by White light cystoscopy? What is the proportion of patients who have at least one specific kind of lesion found by Blue light cystoscopy with Hexvix but not by White light cystoscopy? What is the proportion of false positive lesions detected with Hexvix Blue light cystoscopy and White light cystoscopy? What is the proportion of patients with Adverse Events (AE) during the study?

Phase 3
Interventional Study Model
Single Group Assignment
Model Description
This is a prospective, comparative, within patient controlled, multi-center study of Hexvix Blue light cystoscopy and standard White light cystoscopy in the detection of bladder cancer. Patients with suspicious or confirmed bladder cancer will be enrolled and there will be a maximum of three regular study visits for each patient. Visit 1 is a screening visit, Visit 2 is the cystoscopic examinations and Visit 3 is the safety follow-up. At Visit 2, enrolled patients will be instilled with 50 mL Hexvix solution in the bladder for one hour. After bladder evacuation, the inspection of the bladder and mapping of lesions seen under White light will be done. Secondly, inspection of the bladder and mapping of lesions seen under Blue light will be done. The Richard Wold PDD system (System Blue) will be used. Lesions detected will be resected or biopsied and sent to the local and central pathologists for analysis.
