  • Ophthalmic Adverse Reaction [see WARNINGS AND PRECAUTIONS]
  • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]
  • Non-Melanoma Skin Cancer [see WARNINGS AND PRECAUTIONS]

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.

The data described below reflect exposure to Picato gel in 499 subjects with actinic keratosis, including 274 subjects exposed to Picato gel field treatment (skin area of 25 cm2 in the face or scalp regions) at a concentration of 0.015% once daily for 3 consecutive days, and 225 subjects exposed to Picato gel field treatment (skin area of 25 cm2 in the trunk or extremities regions) at a concentration of 0.05% once daily for 2 consecutive days.

Local skin reactions, including erythema, flaking/scaling, crusting, swelling, vesiculation/pustulation, and erosion/ulceration were assessed within the selected treatment area and graded by the investigator on a scale of 0to4.Agradeof 0representednoreactionpresentinthetreatedarea,andagradeof 4indicated amarkedand severe skin reaction that extended beyond the treated area.

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Ophthalmic Adverse Reactions

Eye disorders, including severe eye pain, chemical conjunctivitis, corneal burn, eyelid edema, eyelid ptosis, periorbital edema can occur after exposure [see ADVERSE REACTIONS].

To avoid transfer of the drug into the eyes and to the periocular area during and after application, patients should wash hands well after applying Picato gel. If accidental exposure occurs, the area should be flushed with water and the patient should seek medical care as soon as possible.

Hypersensitivity Reactions

Hypersensitivity reactions, including anaphylaxis and allergic contact dermatitis, have been reported postmarketing. If anaphylactic or other clinically significant hypersensitivity reactions occur, discontinue Picato gel immediately and institute appropriate medical therapy.

Non-Melanoma Skin Cancer

Non-melanoma skin cancers have been reported in patients treated with Picato. Cases of rapidly growing squamous cell carcinoma have been reported in the treatment area within a few weeks after treatment completion. Counsel patients on the potential risk and monitor closely those patients with risk factors for skin cancer.

Local Skin Reactions

Severe skin reactions in the treated area, including erythema, crusting, swelling, vesiculation/pustulation, and erosion/ulceration, can occur after topical application of Picato® gel [see ADVERSE REACTIONS]. Administration of Picato gel is not recommended until the skin is healed from any previous drug or surgical treatment.

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use).

Ophthalmic Adverse Reactions

Inform patients that severe eye injury can occur with Picato gel. Advise patients that Picato gel is not for ophthalmic use. Advise patients to avoid application around the eyes. If severe eye pain or other symptoms of accidental exposure occur, advise patients to flush eyes with water and seek medical care [see WARNINGS AND PRECAUTIONS].

Hypersensitivity Reactions

Inform patients that hypersensitivity reactions can occur with Picato gel. Advise patients of the symptoms of allergic reactions and anaphylaxis, and instruct patients to seek immediate medical attention if these symptoms occur [see WARNINGS AND PRECAUTIONS].

Non-Melanoma Skin Cancer

Inform patients that non-melanoma skin cancers have been reported in patients treated with Picato.Instruct patients to notify their physician if any new or changing skin lesions occur in the treatment area after treatment completion [see WARNINGS AND PRECAUTIONS].

Local Skin Reactions

Inform patients that treatment with Picato gel may lead to local skin reactions [see WARNINGS AND PRECAUTIONS].

Important Administration Instructions

Advise patients that Picato® gel is for external use only. Advise patients to avoid application near and around the eyes, mouth and lips.

Patients should avoid inadvertent transfer of Picato gel to other areas, or to another person. Instruct patients to:

  • allow the treated area to dry for 15 minutes after application.
  • avoid washing and touching the treated area, or participating in activities that cause excessive sweating, for 6 hours after treatment. Following this time, patients may wash the area with a mild soap and water.
  • keep out of the reach of children.
Lactation

Advise breastfeeding women to avoid accidental transfer of Picato gel to the nipple and areola area to prevent direct infant exposure [see Use In Specific Populations].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Long-term animal studies have not been performed to evaluate the carcinogenic potential of Picato® gel or ingenol mebutate. The effects of ingenol mebutate on fertility have not been evaluated.

Ingenol mebutate was negative in the Ames test, in vitro mouse lymphoma assay, and in vivo rat micronucleus test, but positive in the Syrian hamster embryo (SHE) cell transformation assay.

Use In Specific Populations

Pregnancy

Risk Summary

There are no available data on Picato gel use in pregnant women to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Systemic concentrations following topical administration of Picato gel were below the limit of quantification of 0.1 ng/ml, and maternal use is not expected to result in fetal exposure to the drug [see CLINICAL PHARMACOLOGY].

In animal reproduction studies, ingenol mebutate did not cause malformations in pregnant rats and rabbits when given by the intravenous route of administration during the period of organogenesis (see Data). The available data do not allow the calculation of relevant comparisons between the systemic exposure of ingenol mebutate observed in the animal studies to the systemic exposure that would be expected in humans after topical use of Picato® gel.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of major birth defects, loss, and other adverse outcomes. The background risk in the U.S. general population of major birth defects is 2 to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies.

Data

Animal Data

Intravenous doses of 1.5, 3, and 5 μg/kg/day (9, 18, and 30 μg/m2/day, respectively) ingenol mebutate were administered during the period of organogenesis (gestational days 6 – 16) to pregnant female rats. No treatment-related effects on embryofetal development or malformations were noted at doses up to 5 μg/kg/day (30 μg/m2/day).

Intravenous doses of 1, 2, and 4 μg/kg/day (12, 24, and 48 μg/m2/day, respectively) ingenol mebutate were administered during the period of organogenesis (gestational days 6 – 18) to pregnant female rabbits. Maternal toxicity (increased breathing rate) was observed at doses ≥ 1 μg/kg/day (12 μg/m2/day). An increase in embryo-fetal mortality was noted at 4 μg/kg/day (48 μg/m2/day). An increased incidence of fetal visceral and skeletal variations was noted in all three ingenol mebutate dose groups.

Lactation

Risk Summary

There are no data on the presence of ingenol mebutate in human or animal milk, the effects on the breastfed infant or the effects on milk production. Systemic concentrations following topical administration of Picato® gel were below the limit of quantification of 0.1 ng/mL, and breastfeeding is not expected to result in exposure of the child to Picato gel [see CLINICAL PHARMACOLOGY]. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Picato gel and any potential adverse effects on the breastfed infant from Picato gel or from the underlying maternal condition.

Clinical Considerations

Advise breastfeeding women to avoid accidental transfer of Picato gel to the nipple and areola area to prevent direct infant exposure.

Pediatric Use

Actinic keratosis is not a condition generally seen within the pediatric population.

The safety and effectiveness of Picato gel for actinic keratosis in patients less than 18 years of age have not been established.

Geriatric Use

Of the 1165 subjects treated with Picato gel in the clinical trials, 56% were 65 years and older and, 21% were 75 years and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects.

Overdosage & Contraindications

OVERDOSE

Topical overdosing of Picato gel could result in an increased incidence of local skin reactions.

CONTRAINDICATIONS

Picato gel is contraindicated in patients with known hypersensitivity to ingenol mebutate or any component of the formulation. Anaphylaxis, as well as allergic reactions leading to hospitalization have been reported in postmarketing use with Picato gel [see WARNINGS AND PRECAUTIONS].

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

The mechanism of action by which Picato gel induces cell death in treating AK lesions is unknown.

Pharmacodynamics

The pharmacodynamics of Picato gel is unknown.

Pharmacokinetics

Absorption

The systemic exposure to Picato gel, 0.05% was assessed in two studies in a total of 16 subjects with AK, following application of approximately 1 g of Picato gel, 0.05% to an area of 100 cm2 of the dorsal forearm once daily for two consecutive days. In these studies, the blood levels of ingenol mebutate and two of its metabolites (acyl isomers of ingenol mebutate) were measured. Blood levels of ingenol mebutate and the two metabolites were below the lower limit of quantification (0.1 ng/mL) in all the blood samples of the subjects evaluated.

Drug Interactions

In vitro studies demonstrated that [3H]-ingenol mebutate undergoes extensive metabolism in human hepatocytes.

In vitro studies to assess the potential of ingenol mebutate to inhibit or induce human cytochrome P450 (CYP) enzymes demonstrated that ingenol mebutate does not inhibit CYP 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A4 or induce CYP 1A2, 2C9, and 3A4. The estimated expected systemic exposure (< 0.1 ng/mL) following topical application of Picato® gel, 0.05% to AK subjects in the pharmacokinetic studies described above is negligible compared to the concentrations of ingenol mebutate evaluated in the in vitro studies.

Clinical Studies

Actinic Keratosis Of The Face And Scalp

In two double-blind, vehicle-controlled, clinical trials, 547 adult subjects with AK on the face or scalp were randomized to treatment with either Picato gel, 0.015% or vehicle gel for 3 consecutive days, followed by an 8 week follow-up period. The trials enrolled subjects with 4 to 8 clinically typical, visible, discrete AK lesions within a 25 cm2 contiguous treatment area. Hypertrophic and hyperkeratotic lesions were excluded from treatment. On each scheduled dosing day, the study gel was applied to the entire treatment area. A total of 536 subjects (98%) completed these trials. Study subjects ranged from 34 to 89 years of age (mean 64 years) and 94% had Fitzpatrick skin type I, II, or III. Approximately 85% of subjects were male, and all Picato gel-treated subjects were Caucasian.

Efficacy was assessed at Day 57. Complete clearance rate was defined as the proportion of subjects with no (zero) clinically visible AK lesions in the treatment area. Partial clearance rate was defined as the proportion of subjects with 75% or greater reduction in the number of AK lesions at baseline in the selected treatment area. Table 5 presents the efficacy results for each trial.

Subjects who achieved complete clearance at Day 57 in Study 1 and Study 2 entered a 12-month follow-up period. Based on 108 Picato gel-treated subjects who achieved complete clearance in Study 1 and Study 2, the recurrence rate at 12 months was 54% where recurrence was defined as the percentage of subjects with any identified AK lesion in the previously treated area who achieved complete clearance at Day 57.

Actinic Keratosis Of The Trunk And Extremities

In two double-blind, vehicle-controlled clinical trials, 458 adult subjects with AK on the trunk or extremities were randomized to treatment with either Picato® gel, 0.05% or vehicle gel for 2 consecutive days, followed by an 8 week follow-up period. The trials enrolled subjects with 4 to 8 clinically typical, visible, discrete AK lesions within a 25 cm2 contiguous treatment area. Hypertrophic and hyperkeratotic lesions were excluded from treatment. On each scheduled dosing day, the study gel was applied to the entire treatment area. A total of 447 subjects (98%) completed these trials. Study subjects ranged from 34 to 89 years of age (mean 66 years) and 94% had Fitzpatrick skin type I, II, or III. Approximately 62% of subjects were male, and all Picato gel-treated subjects were Caucasian.

Efficacy was assessed at Day 57. Complete clearance rate was defined as the proportion of subjects with no (zero) clinically visible AK lesions in the treatment area. The partial clearance rate was defined as the proportion of subjects with 75% or greater reduction in the number of AK lesions at baseline in the selected treatment area.

Subjects who achieved complete clearance at Day 57 in Study 4 entered a 12-month follow-up period. Based on 38 Picato® gel-treated subjects who achieved complete clearance in Study 4, the recurrence rate at 12 months was 50% where recurrence was defined as the percentage of subjects with any identified AK lesion in the previously treated area who achieved complete clearance at Day 57.

In a separate trial, in an open-label treatment period, subjects were treated for AK lesions on their face or scalp. Those subjects who did not achieve clearance at Day 57 or experienced recurrence after achieving clearance at Day 57 were randomized to receive a second treatment course of Picato gel or its vehicle gel. Some subjects had a treatment benefit with the second treatment course of Picato gel when evaluated 8 weeks after the retreatment.
