Trial summary

In 2005, the EBCIG demonstrated the efficacy of tamoxifen in improving overall survival in hormone receptor positive breast cancers. However, tamoxifen shows partial estrogen agonist activity, which is responsible for the drug's detrimental effects such as endometrial carcinoma, thromboembolism, and tamoxifen… Read more about this study

About this study

In 2005, the EBCIG demonstrated the efficacy of tamoxifen in improving overall survival in hormone receptor positive breast cancers. However, tamoxifen shows partial estrogen agonist activity, which is responsible for the drug's detrimental effects such as endometrial carcinoma, thromboembolism, and tamoxifen resistance. More recently, aromatase inhibitors have been shown to be superior to tamoxifen in the metastatic and adjuvant settings. The ATAC trial demonstrated improved disease-free survival (DFS) for 5 years of anastrozole compared to 5 years of tamoxifen 3. The BIG 1-98 trial results demonstrated that after a median follow-up of 25.8 months, letrozole improved DFS and distant DFS when compared to tamoxifen. Based on these results, adjuvant hormonal therapy with Aromatase Inhibitors (AI) has become the preferred therapy for post-menopausal woman.

However, AI therapy is also associated with toxicities that merit in-depth studies, one of them being an increase in musculoskeletal pain. In the ATAC trial, at a median follow-up of 5.7 years, arthralgia was significantly higher (35.6% vs. 29.4%) and fractures were also increased (11.0% vs. 7.7%) when anastrozole was administered for 5 years following surgery with or without chemotherapy 3. The incidence of arthralgia was also significantly higher in the MA-17 trial, with 25% of patients receiving letrozole developing arthralgia compared with 21% in the placebo group following 5 to 6 years of tamoxifen 5.

Traditionally in cancer clinical trials, the reporting of musculoskeletal pain has been based on the "Common Terminology Criteria for Adverse Events", which covers a wide range of symptoms and does not facilitate the documentation of a pain syndrome in a specific manner. Therefore, there is a need to design a study that will describe the nature of the pain associated with the administration of AI therapy using tools that have been validated for capturing a multidimensional phenomenon such as pain.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Centre hospitalier de l'Université de Montréal (CHUM) at 1 site in Canada.

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 8 inclusion and 8 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 24 Aug 2020. 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 Canada. 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?

Musculoskeletal pain (time frame: Every two weeks). 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 24 Aug 2020.
