10 Clinical Trials for Various Conditions
This study will collect 5 year data about any possible health problems associated with breast implants. This data will be used to help see if the implants are both safe and effective. If they are proven safe and effective, they will continue to be available. If they are not proven safe and effective to the satisfaction of the FDA, they may not be available in the future.
The Core Gel Study is designed to demonstrate safety and effectiveness of Mentor's Round Low-Bleed Silicone Gel-filled Mammary Prostheses in women who are undergoing primary augmentation, primary reconstruction, or revision. Safety information on the rate of capsular contracture, rupture, and infection will be collected, and used to help determine device safety. Approximately 1000 patients at centers across the United States will be enrolled in this research study. These patients will be implanted with silicone breast prostheses and monitored for 10 years to collect information on risks associated with the implant surgery as well as changes in the way these patients feel about themselves.
This is a ten-year postapproval study to evaluate the long-term clinical performance of Sientra Silicone Gel Breast Implants under general conditions of use in the postmarket environment.
Safety and effectiveness of the Silimed Gel-Filled Mammary Implant as indicated for primary augmentation, primary reconstruction, and/or revision of the female breast.
Safety and effectiveness of Natrelle™ Cohesive Round Silicone-Filled Breast Implants in women undergoing primary reconstruction or revision of existing breast implants.
Safety and effectiveness of Style 410 Silicone-Filled Breast Implants in women undergoing primary augmentation, primary reconstruction, or revision of existing breast implants.
Safety and effectiveness of Natrelle™ Cohesive Round Silicone-Filled Breast Implants in women undergoing primary augmentation, primary reconstruction, or revision of existing breast implants.
The CPG Styles Study is designed to demonstrate the safety of different styles of Mentor's Contour Profile Gel (CPG) breast implants in women who are undergoing primary augmentation, primary reconstruction, or revision. Safety information on the rate of capsular contracture, rupture and infection will be collected and used to determine device safety.
This is a prospective, multicenter study of the safety and effectiveness of NATRELLE® 410 Highly Cohesive, Anatomically Shaped, Silicone-Filled X-Style and L-Style Breast Implants.
This study will examine long-term health effects of cosmetic breast augmentation (enlargement) with silicone gel breast implants. There has been concern for some time about the possible effects of breast implants on the immune system particularly regarding the development of certain connective tissue disorders and on the possibility that implants may interfere with the ability to detect breast cancers. More recently, concerns have been raised regarding the possible cancer-causing effect of the implants themselves. These concerns were heightened by reports that the polyurethane foam coating that envelops the silicone gel in some implants may dissolve and produce a chemical called 2,4,-diamino toluene (TDA), which has been linked to an increased risk of breast and other cancers in rats and mice. To address this issue, this study will gather information from the medical records and a questionnaire survey of approximately 12,000 breast implant patients. The questionnaire will request information on perceived complications of the implants; history of breast examinations and mammograms; frequency of breast self examination; development of diseases (particularly cancers and connective tissue disorders) developed subsequent to the augmentation surgery; potential risk factors for these diseases, such as age at menarche (onset of menstruation), age at first birth, age and type of menopause (natural or due to surgery); history of breast biopsies; immune system and connective tissue disorders; cigarette smoking; alcohol consumption; family medical history, and so forth. To evaluate the results, the information will be compared with the same data on 4,000 women who underwent other plastic surgery procedures, such as rhinoplasty, facelift, liposuction, dermabrasion, eyelifts, and others, from the same practices as the breast augmentation patients. Participants will be recruited for the study from several large reconstructive and plastic surgery practices. Among the breast implant patients, women who have had bilateral breast implants for cosmetic purposes only, and not as breast reconstruction after breast cancer surgery, will be eligible. Women with a history of breast cancer may not participate.
