Side effects of Klisyri include:

  • local skin reactions (itching, pain, redness, flaking/scaling, crusting, swelling, blisters, and ulceration)

Dosage for Klisyri

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Two double-blind, vehicle-controlled clinical trials were conducted in 702 adult subjects with actinic keratosis on the face or scalp. Subjects were randomized 1:1 to KLISYRI or vehicle. Subjects enrolled in the trials had 4 to 8 clinically typical, visible, and discrete AK lesions in a contiguous area of 25 cm² on the face or scalp. Subjects had an average age of 70 years (range 45 to 96 years) and were predominantly Caucasian (99%), male (87%), with Fitzpatrick skin types I or II (72%) and actinic keratosis on the face (68%) or scalp (32%). Treatment groups were comparable across all demographics and baseline characteristics, including AK lesion count and distribution on the face or scalp.

In the controlled trials, local skin reactions (LSRs) were collected independent of adverse events. Local skin reactions including erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, erosions/ulcerations were assessed by the investigators using a grading scale of 0 = absent, 1 = mild (slightly, barely perceptible), 2 = moderate (distinct presence), and 3 = severe (marked, intense).

The percentages of subjects with the maximal post-baseline grades for each local skin reaction greater than baseline by treatment group are provided in Table 1. LSRs were mostly mild to moderate in degree (Table 1).

Table 2 presents the adverse reactions experienced in ≥2% of subjects participating in the controlled clinical trials with KLISYRI. No subject withdrew from the trials due to adverse reactions.

a Application site pain includes pain, tenderness, stinging, and burning sensation at the application site.

For the 51 subjects (45 KLISYRI, 6 vehicle) who maintained complete clearance through the 12-month follow-up period, no additional local adverse reactions were reported.

Dermal Safety Studies

Clinical studies in healthy subjects demonstrated KLISYRI did not cause contact sensitization (261 subjects), phototoxic skin reactions (31 subjects), or photoallergic skin reactions (64 subjects).
