Side Effects

6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥2%) are local skin reactions, application site pruritus, and application site pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Almirall, at 1-866-665-2782 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 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.

Warnings

5 WARNINGS AND PRECAUTIONS Ophthalmic Adverse Reactions: May cause eye irritation upon ocular exposure. Avoid transfer of the drug into the eyes and to the periocular area. If accidental exposure occurs, flush eyes with water and seek medical care. ( 5.1 ) Local Skin Reactions: Local skin reactions can occur including severe reactions (e.g., vesiculation/pustulation, erosion/ulceration) in the treated area. Avoid use until skin is healed from any previous drug or surgical treatment. ( 5.2 ) 5.1 Ophthalmic Adverse Reactions KLISYRI may cause eye irritation. Avoid transfer of the drug into the eyes and to the periocular area during and after application. Wash hands immediately after application. 4 CONTRAINDICATIONS None. None. ( 4 )

Pregnancy

8.1 Pregnancy Risk Summary There are no available data with KLISYRI use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of tirbanibulin to pregnant rats during the period of organogenesis resulted in an increased incidence of fetal deaths and malformations at a systemic exposure that was at least 19 times the exposure associated with the maximum recommended human dose (MRHD).

Storage

Store at 20°C-25°C (68°F-77°F), excursions permitted to 15°C-30°C (59°F-86°F) [see USP Controlled Room Temperature]. Do not refrigerate or freeze.
