Aczone® (dapsone) Gel, 7.5% Now Approved for the Topical Treatment of Acne Vulgaris in Patients 9 Years of Age and Older
EXTON, Pa., Sept. 10, 2019 /PRNewswire/ — Almirall LLC announced today the FDA approval of the expanded indication for Aczone® 7.5% Gel to include patients aged 9-11. Aczone® 7.5% Gel is a prescription medicine used on the skin (topical) to treat inflammatory and non-inflammatory acne, previously approved in February 2016 for patients 12 and older.
«While acne may be commonly thought of as an issue for teenagers, according to treatment guidelines, acne is also prevalent in children under the age of 12,»2 explains clinical study investigator and pediatric dermatologist, Adelaide Hebert, MD, of McGovern Medical School at UTHealth Houston. «Research revealed that treatment options like Aczone® 7.5% Gel can be used in these younger individuals who are living with the detrimental effects of acne.»
The expanded approval was based on data from an open-label safety study to assess safety, pharmacokinetics, and treatment effect of Aczone® Gel, 7.5% in 101 patients 9 to 11 years of age with acne vulgaris. Aczone® 7.5% Gel was determined to be safe and effective in this patient population.
«Acne is linked to the onset of puberty, which may start earlier,3 and pre-teen children are an impressionable age group prone to the emotional and psychosocial implications of the disease. Almirall is therefore pleased to be able to offer this FDA approved treatment option which is proven to be safe and effective in children 9 to 11 years old,»4 states Ayman Grada, MD, Director of Medical Affairs and R&D at Almirall, LLC.
Aczone® 7.5% Gel is one of thirteen branded products marketed in the US by Almirall, a global family-owned company focused on medical dermatology and skin health. Ron Menezes, President and General Manager at Almirall, LLC, underscores: «We are very pleased to announce this expanded indication for Aczone® 7.5% Gel which further demonstrates Almirall’s commitment to our patients and to continuous innovation in medical dermatology.»
ACZONE® (dapsone) Gel, 7.5%, is indicated for the topical treatment of acne vulgaris in patients 9 years of age and older.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Methemoglobinemia: Cases of methemoglobinemia with resultant hospitalization have been reported post marketing in association with twice-daily dapsone gel 5% treatment. Patients with glucose-6-phosphate dehydrogenase deficiency or congenital or idiopathic methemoglobinemia are more susceptible to drug-induced methemoglobinemia. Avoid use of ACZONE® Gel 7.5% in patients with congenital or idiopathic methemoglobinemia. Signs and symptoms of methemoglobinemia may be delayed some hours after exposure. Initial signs and symptoms of methemoglobinemia are characterized by a slate-gray cyanosis seen in, eg, buccal mucous membranes, lips, and nail beds. Advise patients to discontinue ACZONE® Gel 7.5% and seek immediate medical attention in the event of cyanosis. Dapsone can cause elevated methemoglobin levels, particularly in conjunction with methemoglobin-inducing agents.
Hemolysis: Oral dapsone treatment has produced dose-related hemolysis and hemolytic anemia. Individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency are more prone to hemolysis with the use of certain drugs. G6PD deficiency is most prevalent in populations of African, South Asian, Middle Eastern, and Mediterranean ancestry. In clinical trials, there was no evidence of clinically relevant hemolysis or hemolytic anemia in subjects treated with topical dapsone. Some subjects with G6PD deficiency using dapsone gel 5% twice daily developed laboratory changes suggestive of hemolysis. Discontinue ACZONE® Gel 7.5% if signs and symptoms suggestive of hemolytic anemia occur. Avoid use of ACZONE® Gel 7.5% in patients who are taking oral dapsone or antimalarial medications because of the potential for hemolytic reactions. Combination of ACZONE® Gel 7.5% with trimethoprim/sulfamethoxazole (TMP/SMX) may increase the likelihood of hemolysis in patients with G6PD deficiency.
Peripheral neuropathy (motor loss and muscle weakness) has been reported with oral dapsone treatment. No events of peripheral neuropathy were observed in clinical trials with topical dapsone treatment.
Skin reactions (toxic epidermal necrolysis, erythema multiforme, morbilliform and scarlatiniform reactions, bullous and exfoliative dermatitis, erythema nodosum, and urticaria) have been reported with oral dapsone treatment. These types of skin reactions were not observed in clinical trials with topical dapsone treatment.
The most common adverse reactions of ACZONE® Gel 7.5% are dryness and pruritus at the application site. Methemoglobinemia has been identified during postmarketing use of topical dapsone.
Topical application of dapsone gel followed by benzoyl peroxide in patients with acne vulgaris may result in a temporary local yellow or orange discoloration of the skin and facial hair.
