Trial summary

Specific aim: To establish the proof of principle that treatment of "high breast cancer risk" women with recombinant human chorionic gonadotropin (r-hCG) will change their breast epithelium's high risk genomic profile to one similar to that identified in women with a history of early full first term pregnancy.

About this study

Official title: The Use of Recombinant hCG to Prevent Breast Cancer in BRCA1 and BRCA2 Carriers

Specific aim: To establish the proof of principle that treatment of "high breast cancer risk" women with recombinant human chorionic gonadotropin (r-hCG) will change their breast epithelium's high risk genomic profile to one similar to that identified in women with a history of early full first term pregnancy.

Read the detailed description

This study is based on the investigators preclinical data that have demonstrated that r-hCG exerts a mammary cancer preventive effect that is mediated by the induction of gland differentiation, which results in permanent changes in the genomic signature of this organ. This exploratory study will evaluate the genomic profile of breast epithelial cells obtained from random periareolar fine needle aspiration (RPFNA) specimens performed in high risk women treated for 90 days (an extra 4 weeks in a subgroup) with r-hCG. This knowledge will serve as the basis for establishing a novel genomic biomarker that will serve as a surrogate endpoint in future preventive clinical trials.

The objective of the proposed study is to characterize the genomic profile of breast epithelial cells obtained from 35 asymptomatic high breast cancer risk nulliparous premenopausal women carriers of BRCA1 and BRCA2 deleterious mutations. Gene expression measurements and benign breast tissue specimens will be obtained at baseline (time 0), after treatment with r-hCG at 90 days (time 1), at 270 days from baseline (time 2) and (in a subgroup) at 60 weeks (+/- 4 weeks).

The primary objective of the study is to compare the gene expression profiles of these women across the three (or four) time points and identify differentially expressed genes. The investigator is interested in comparing the expression profiles between all pairs of time points as well as across time. The comparison of profiles before and after treatment with r-hCG, both at 90 and 270 days are of particular interest. The women will receive 3x/week injections of 250 microgram r-hCG for a total of 12 weeks (an extra 4 weeks in a subgroup). Core Needle Biopsies specimens will be primarily utilized for analysis of genomic expression by cDNA microarray. In addition, a series of surrogate intermediate markers such as cytomorphologic evaluation and cell proliferation index will be analyzed.

What participants receive

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

  • OvitrelleDrug

    Ovitrelle will be injected in 35 asymptomatic women with BRCA1 or BRCA2 mutation during 90 days (an extra 4 weeks in a subgroup). The gene expression of the breast epithelial cells will be characterized and compared to the gene expression of the breast epithelial cells before ovitrelle injection.

What is being measured

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

  1. Does Ovitrelle result in early prevention of breast cancer in BRCA1 and BRCA2 carriers?

    The investigators are expecting that r-hCG is inducing genomic signature of protection in the breast. Participants will receive a subcutaneous injection of recombinant hCG three times a week for 12 (or 16) weeks. Normal breast tissue specimens will be collected by Spirotome at the beginning of treatment (day 0), at the end of treatment (week 13) and at 36 weeks. The specimens will be primarily utilized for analysis of genomic expression by cDNA microarray, RNA sequencing and epigenomic studies. In addition, a series of surrogate intermediate markers such as cytomorphologic evaluation and cell proliferation index will be analyzed. The primary objective is to compare the gene expression, and epigenomic profiles of sampled breast epithelial cells across the three time points and identify differentially expressed or silenced genes.

    Measured: 48 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ovitrelle in people with hCG and BRCA1 Mutation, run by University Hospital, Ghent at 1 site in Belgium.

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 9 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 7 Sep 2023. 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 Belgium. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Does Ovitrelle result in early prevention of breast cancer in BRCA1 and BRCA2 carriers? (time frame: 48 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 7 Sep 2023.
