Almirall’s Seysara Label Update on Resistance

Share

FDA has approved a label update for Almirall’s Seysara (sarecycline) stating that P. acnes strains displayed a low propensity for developing resistance to sarecycline. This information is included in the Microbiology Section (12.4) of the prescribing information, the company says. Seysara, which was approved 10/2018, is described as a novel tetracycline-derived oral antibiotic developed specifically for treating acne. It is indicated for treating inflammatory lesions of non-nodular moderate to severe acne vulgaris in patients nine years of age and older.

 

Almirall says the label update is based on data that demonstrated that P. acnes strains display low propensity for developing resistance to sarecycline, with spontaneous mutation frequencies being about 1 in 10 billion at four to eight times the minimum inhibitory concentration. This means that the main bacterium associated with acne has shown a very low potential of developing resistance to sarecycline, it says.
