About this study
Research Problem:

Research Significance:
The present study will employ a new photodynamic diagnostic procedure to quantify a certain cancer specific biomarker called Porphyrin, which selectively binds on to the bladder cancer tissues. In this context the present technique offer viable, very easy and reliable table top instrumentation for diagnosis and continual monitoring of disease regression through urine.
Research Objectives:
- To quantify bladder cancer specific biomarkers such as Porphyrin using photodynamic diagnostic procedure
- To find out whether this technique might be a new and easy tool for bladder cancer diagnosis only by urine.
Research Methodology:
The bladder cancer patients is required to swallow a chemical called ALA (5 Amino levulinic Acid hydrochloride), about 10mg/kg body weight which will play a role of biological indicator. ALA gets metabolized into certain types of porphyrins which selectively bind on to the tumor tissues (for a longer time than the normal tissues). 5ml of blood and one urine samples will be taken before using ALA. The patient must drink water then the urine will be collected after 4, 8 and 12 hours of taking ALA and the samples will be analyzed by photodynamic diagnostic procedure.
Read the detailed description
Bladder cancer is one of the most common urologic cancers in Saudi Arabia. its cases represent a significant and challenging part in the daily practice for the majority of urologists practicing. The present methods of diagnosis are: Ultra sound, Cystoscopy, CT-scan etc. All these are stressful to the patients, particularly Cystoscopy which is commonly employed for the follow up of Bladder cancer patients.
In recent years, fluorescence cystoscopy, in contrast to conventional white light cystoscopy, has been investigated as a tool to enhance detection of occult papillary lesions and carcinoma in situ. Recent fluorescence photo detection strategies have used 5-aminolevulinic acid (5-ALA); a precursor of heme biosynthesis.
5-Aminolevulinic acid-enhanced cystoscopy does appear to have improved sensitivities in detecting nonmuscle invasive bladder tumors such as carcinoma in situ . Aminolevulinic acid (ALA) may have a role in other applications in surgical oncology based on its ability to discriminate neoplastic tissue from adjacent normal tissue. Aminolevulinic acid is not a photosensitizer, but rather a metabolic precursor of porphyrin, which is a photosensitizer.
The present study will employ photodynamic diagnostic procedure to quantify only in urine a specific cancer biomarker Porphyrin which selectively binds on to the bladder cancer tissues for a longer time than the normal tissues. In this context, the present study will offer viable, very easy and reliable table top instrumentation for diagnosis and continual monitoring of disease regression.

The patient must drink water then the urine will be collected after 4, 8 and 12 hours of taking ALA and the samples will be analyzed by photodynamic diagnostic procedure.

|---|---|---|
| Urine spectral analysis | Experimental | The patient must drink water then the urine will be collected after 4, 8 and 12 hours of taking Amino levulinic Acid and the samples will be analyzed by photodynamic diagnostic procedure. Amino levulinic Acid gets metabolized into certain types of porphyrins which selectively bind on to the tumor tissues (for a longer time than the normal tissues).The above samples is taken in a four side polished quartz cuvette of 1cmx1cmx4cm and put into the table top spectral scan. This consists of a 5 mw, blue diode laser, of 405nm wavelength. The collimated laser beam falls on the urine sample and excites fluorescence and Raman signals from the porphyrin molecules which have been metabolized from the oral administration of Amino levulinic Acid.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Amino levulinic Acid in people with Transitional Cell Carcinoma of the Bladder, run by Princess Al-Johara Al-Ibrahim Cancer Research Center at 1 site in Saudi Arabia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Saudi Arabia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Urine spectral profile after four hours (time frame: Four hours after taking Amino levulinic Acid). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2016.
