Flaking/scaling and itching, followed by dry cracked skin that may bleed, pain or soreness, and burning/stinging were noted by psoriasis patients as the symptoms with the most significant impact on daily life in a public meeting hosted by the US Food and Drug Administration (FDA) to hear patient perspectives on psoriasis. Approximately 70 psoriasis patients or patient representatives attended the meeting in person and others attended through a live webcast.
More than two-thirds of respondents identified flaking/scaling as one of their most significant symptoms of psoriasis, either localized to psoriasis-prone areas such as the elbows and knees or more widespread. Patients reported that this symptom is constant, leaving them to absentmindedly rub certain areas of the skin.
A similar number of respondents indicated that itching was their most significant symptom. One patient called it “an intense subcutaneous itch… deep down in the skin,” a description that resonated with other patients in the room.
Nearly 40% identified dry cracked skin that may bleed as a significant symptom, noting that areas where skin is thinner are affected more, such as the folds of the body. Patients described this symptom as interrelated with other symptoms such as itching. “The thicker the scales get on my skin, the more they itch, and the more they itch, the more I am likely to scratch them, and the more I scratch them, the more they start to crack, and then more come back and it keeps going and going,” one patient said.
More than one-quarter of respondents indicated that pain, soreness, or burning/stinging were the most significant symptoms. Patients indicated that the stinging/burning was more episodic, while the pain was more constant, with the pain being under the skin.
Triggers of these symptoms included stress (primary trigger), changes in weather, hormonal changes, diet, lotions, prolonged exposure to sunlight, sweat, aging, and other medical conditions.
Dermatologists may use these patient insights to prescribe therapies that target these symptoms.
The psoriasis public meeting in March 2016 was the FDA’s 18th patient-focused drug development meeting. The FDA sought this information to have a greater understanding of the burden of psoriasis on patients and the treatments currently used to treat psoriasis and its symptoms. This information will help guide the FDA as they consider future drug approvals.
