Study of GalaFLEX LITE™ Scaffold in Treatment of Capsular Contracture After Breast Implant Augmentation

Not Applicable

Recruiting

• Conditions: Capsular Contracture Associated With Breast Implant; Capsular Contracture Grade III; Capsular Contracture Grade IV

• Registration Number: NCT05945329
• Lead Sponsor: C. R. Bard

Brief Summary

Prospective, randomized, controlled study to assess the safety and effectiveness of GalaFLEX LITE™ Scaffold in revision surgery for reduction of capsular contracture recurrence and/or malposition in implant-based breast augmentation patients versus patients undergoing conventional revision surgery with no supportive matrix or acellular dermal matrix (ADM). Subjects will be randomized 2:1 to receive either GalaFLEX LITE™ Scaffold or standard care (no ADM or matrix placement). This study is designed using an adaptive approach. The number of the treated breasts will range between 250 and 530.

Detailed Description

Capsular contracture is the number one complication leading to revision surgery after breast augmentation(2-4) which has been commonly cited as impacting 10 to 20% of all breast augmentation patients.(5-10) A prospective, randomized controlled study of patients presenting with Baker grade III or IV capsular contracture will be undertaken to investigate the ability of P4HB (specifically GalaFLEX LITE™ Scaffold) to reduce the recurrence of clinically significant CC and/or malposition requiring surgical correction. The primary endpoint is a composite of capsular contracture recurrence and/or breast implant malposition recommended for surgery OR breast infections requiring oral or IV antibiotic treatment within 90 days of surgery and/or peri-implant fluid collection needing a drainage procedure within 10-90 days of surgery.

5. Has prior use of a matrix (synthetic or biologic) in the breast(s) intended for treatment.
6. Abnormal findings on diagnostic imaging within 1-year of study enrollment (mammogram for patients ≥35 years old; MRI for patients <35 years old or breast ultrasound if MRI is contraindicated)
7. Has symptoms consistent with Breast Implant Illness (BII)Systemic Symptoms Associated with Breast Implants (SSBI)
