Inspection Derails Lilly Eczema BLA
FDA has issued Eli Lilly a complete response letter due to inspection problems impacting its BLA for lebrikizumab, indicated for treating moderate-to-severe atopic dermatitis (eczema). The agency letter cited findings that arose during a multi-sponsor inspection of a third-party contract manufacturer, according to the company. The letter cited no concerns about the clinical data package, safety or label for lebrikizumab, it says, adding that it will “continue to work closely with the third-party manufacturer and the FDA to address the feedback in order to make lebrikizumab available to patients.”
Lilly describes lebrikizumab as a novel, monoclonal antibody that binds to the interleukin 13 (IL-13) protein. IL-13 plays a large role in Type 2 inflammation in atopic dermatitis (AD), it says. The submission contained data from ADvocate 1, ADvocate 2 and ADhere studies, Lilly says, which included over 1,000 adults and adolescents (ages 12 and older) with moderate-to-severe eczema who were unable to control their symptoms with topical medicines or other systemic treatments. Lilly previously said clinical data showed that the therapy in combination with standard-of-care topical corticosteroids (TCS) achieved at least 75% improvement in overall disease severity compared to a placebo plus TCS. The company said that the data from its Adhere trial also showed improvements in itch, sleep interference, and quality of life when combined with TCS, compared to placebo plus TCS. “Among patients taking lebrikizumab plus TCS, 41% achieved clear or almost clear skin (IGA) at 16 weeks compared to 22%of patients taking placebo plus TCS,” it adds.
Regarding safety, Lilly says data were consistent with prior lebrikizumab studies in AD. “Most adverse events were mild or moderate in severity and nonserious and did not lead to treatment discontinuation,” it says, adding that the most common adverse events for those on lebrikizumab were conjunctivitis (5%) and headache (5%).
