Clinical Studies Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.
Head Lice Infestations
NATROBA was studied in two randomized, active-controlled trials (N=552) in subjects with head lice; Table 1 presents selected adverse events, regardless of relationship to NATROBA, that occurred in at least 1% of subjects.
Table 1: Selected Adverse Events Occurring in at least 1% of Subjects with Head Lice Infestation
|Signs||Natroba (N=552)||Permethrin 1% (N=457)|
|Application site erythema||17 (3%)||31(7%)|
|Ocular erythema||12 (2%)||15 (3%)|
|Application site irritation||5 (1%)||7 (2%)|
Other less common reactions (less than 1% but more than 0.1%) were application site dryness, application site exfoliation, alopecia, and dry skin.
NATROBA was studied in three randomized, double-blind, vehicle-controlled trials (Trial 1, Trial 2, and Trial 3) in 592 subjects with scabies infestation, of which 165 were ages 4-17 and 427 were adults. Subjects received a single application of NATROBA to the skin from the neck to the soles of the feet, which was washed off after a minimum of 6 hours. Table 2 presents adverse reactions related to NATROBA treatment that occurred in at least 1% of subjects.
