Pilot Study of the Predictive Value of TREM1 Expression and Activation in Inflammation and Radio-induced Mammary Fibrosis (TREM-1)

June 20, 2022 updated by: Centre Francois Baclesse, Luxembourg
Breast cancer is the most common cancer in the world. Half of patients with such cancer are treated with radiation therapy. Some patients will develop cutaneous or subcutaneous fibrosis, more or less bothersome. Several studies have shown a correlation between an inflammatory reaction and a protein, called TREM-1. But to date, no link has been proven between TREM-1 and inflammation / fibrosis in the phenomena of fibrosis induced by radiotherapy in patients with breast cancer. Our study aims to understand the involvement of this TREM-1 protein in the development of fibrosis or radio-epidermis in patients with breast cancer.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
