Trial summary

Aims of Research Proposal: 1. To build a DNA bank in association with a comprehensive database of treatment outcomes and toxicities of cancer patients. 2.

About this study

Aims of Research Proposal:

  1. To build a DNA bank in association with a comprehensive database of treatment outcomes and toxicities of cancer patients.
  2. To carry out genotyping of potential candidate genes in relation to specific anti-cancer agents and to correlate genotype with treatment outcomes and toxicities.

The investigators hypothesize that genetic variations between different individuals and ethnic groups may account for inter-individual and inter-ethnic differences in treatment response and toxicities to anti-cancer therapy. The understanding of the contribution of these genetic variations may help to individualize therapy to optimize treatment outcomes and reduce toxicities. Patients will be recruited from the National University Hospital Cancer Centre. Any individual aged 18 or above who has been diagnosed with cancer is eligible. 20 ml of blood will be collected from each subject for DNA extraction and pharmacogenetics analysis. At the time of recruitment, demographic characteristics, cancer history, and past and present cancer treatment history of the study subject will be collected. The patients' progress will be followed up periodically (approximately every 6 months) through the medical records, and subsequent cancer treatments, progression of cancer, and survival outcome will be updated. Follow-up will occur until death. Important treatment information that will be collected include the drug regimen, drug doses, intent of treatment, aematologic and non-haematologic toxicities, and hospitalization episodes that may be related to treatment. Known functional single nucleotide polymorphisms (SNPs) of drug metabolizing enzymes, transporters and targets of different anti-cancer agents will be characterized. More comprehensive genotyping will be carried out in 'outliers' who experience exceptional toxicity or biological response to identify novel functional SNPs using high throughput sequencing techniques. Correlation will be made between genotype and treatment-related outcomes (tumor response, progression-free survival) and toxicities. For selected patients, lymphoblastoid transformation will be carried out to maintain an infinite supply of DNA.

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer, run by National University Hospital, Singapore at 1 site in Singapore.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 14 Jan 2014. 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 Singapore. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Soo Chin Lee, MBBS, MRCP (65 6772 4629, Soo_Chin_Lee@nuhs.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00941200, which also lists 2 linked publications.

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 14 Jan 2014.
