September 1, 2023 updated by: University Hospital, Ghent

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Ovitrelle
Drug: Ovitrelle
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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Does Ovitrelle result in early prevention of breast cancer in BRCA1 and BRCA2 carriers?
Time Frame: 48 weeks
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.
48 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: 60 weeks
The investigators are expecting that r-hCG is inducing genomic signature of protection in the breast.
