What You Need to Know Before You Apply

What is the purpose of this trial?

This trial involves injecting cow-derived collagen into the skin of healthy adults to check for allergic reactions. The goal is to see if their immune system reacts negatively, which would indicate an allergy.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are on any systemic immuno-suppressive therapy or topical treatments on your arms, you may not be eligible if you've used them in the past 3 months.

Is Bovine Atelocollagen safe for human use?

There is no specific safety data available for Bovine Atelocollagen in the provided research articles. ^{1 2 3 4 5}

How does the treatment Bovine Atelocollagen differ from other treatments for this condition?

Bovine Atelocollagen is unique because it involves the use of collagen, a protein that provides structure to various tissues, which may aid in tissue repair and regeneration. Unlike other treatments, it may leverage the natural properties of collagen to support healing processes. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment Bovine Atelocollagen?

Research shows that atelocollagen can help with wound healing in various contexts, such as in dog corneas and cleft palate repair in rabbits, by enhancing tissue repair and reducing scar formation. Additionally, it has been used as a carrier for medications in gene therapy due to its low risk of causing immune reactions. ^{11 12 13 14 15}
