Prospective Study to Assess Tissue Responses After Injection With Biostimulatory Products

Not Applicable

Completed

• Conditions: Injection Site Reaction

• Registration Number: NCT06093815
• Lead Sponsor: Merz North America, Inc.

Brief Summary

The objective of this study is to identify and assess in vivo tissue responses after injection with various biostimulatory products at various timepoints. The study will also provide tissue specimens which will be used in a subsequent study.

Safety endpoint: incidence of adverse events.

Detailed Description

The objective of this study is to identify and assess tissue responses after injection with various biostimulatory products that are already used in the market and have CE approval. The study will assess in vivo tissue responses and provide tissue specimens which will be used in a subsequent study, under a separate protocol.

Assessments under this protocol will include ultrasound of in vivo tissue.

Safety endpoint: incidence of adverse events.
