The Evolution of Cosentyx: Understanding the History of Skin Irritation Concerns

Cosentyx, a biologic medication developed by Novartis, has been a game-changer in the treatment of psoriasis and psoriatic arthritis. However, as with any medication, concerns about skin irritation have been raised over the years. In this article, we'll delve into the history of Cosentyx and explore when skin irritation concerns started to emerge.

Early Years: A Promising Start

Cosentyx, also known as secukinumab, was first approved by the FDA in 2015 for the treatment of moderate to severe plaque psoriasis in adults who had an inadequate response to previous treatments. The medication works by blocking the action of a protein called interleukin-17A (IL-17A), which plays a key role in the development of psoriasis.

Initial Efficacy and Safety

In clinical trials, Cosentyx demonstrated impressive efficacy in reducing psoriasis symptoms, with a significant improvement in skin lesions and a decrease in itching and scaling. Additionally, the medication was generally well-tolerated, with a low incidence of adverse events.

Early Signs of Skin Irritation

While Cosentyx was initially deemed safe and effective, some patients began to report skin irritation concerns, including redness, itching, and burning sensations. These issues were often mild and temporary, but they raised concerns about the medication's long-term safety.

Post-Marketing Surveillance

As more patients received Cosentyx, post-marketing surveillance revealed a higher incidence of skin irritation than initially reported. According to the FDA's Adverse Event Reporting System (FAERS), the most common skin-related adverse events associated with Cosentyx were:

* Erythema (redness of the skin): 1.4% of patients
* Pruritus (itching): 1.2% of patients
* Burning sensation: 0.8% of patients
* Rash: 0.6% of patients

Expert Insights

Dr. Mark Lebwohl, a renowned dermatologist and Professor of Dermatology at the Icahn School of Medicine at Mount Sinai, shares his perspective on the evolution of Cosentyx: "When Cosentyx was first approved, we were excited about its potential to revolutionize the treatment of psoriasis. However, as more patients received the medication, we began to see a higher incidence of skin irritation. While these issues are often mild, they can be significant for patients who experience them."
