About this study

Official title: ABCB1 Single Nucleotide Polymorphism Genotypes as Predictors of Paclitaxel-Induced Peripheral Neuropathy in Breast Cancer

The study aim is to determine the allele frequencies of 1236 G>A and 3435 G>A in ABCB1 and study their association with the incidence and severity of paclitaxel-induced peripheral neuropathy while adjusting for other baseline covariates in Egyptian patients. Additionally, the study aimed at fitting and validating logistic regression models with the aforementioned SNPs evaluated in additive, dominant, overdominant, and recessive genetic models and performing diagnostics for the best model in terms of internal validity.

Being tested
Real-Time PCR
Medical subject headings
Neuritis, Breast Neoplasms

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Real-Time PCRGenetic

    Genomic DNA was extracted from 2 ml of venous blood. ABCB1 1236 G>A and 3435 G>A were genotyped using predesigned TaqMan SNP genotyping assays on a stepOne PCR instrument in accordance with the manufacturer's protocol.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Grade 2 or higher peripheral neuropathy

    Grade 2 or higher peripheral neuropathy evaluated by the National Cancer Institute Common Toxicity Criteria (version 5.0)

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Paclitaxel Adverse Reaction and Neuropathy;Peripheral, run by Ain Shams University at 1 site in Egypt.

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 7 inclusion and 6 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 26 Oct 2021. 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 Egypt. 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?

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?

Grade 2 or higher peripheral neuropathy (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05093023, which also lists 9 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 26 Oct 2021.
