Novartis is to discontinue development of the small molecule drug fevipiprant as a treatment for asthma following the failure of two Phase 3 studies to show a reduction in the rate of moderate-to-severe exacerbation compared with placebo. A pooled analysis of the LUSTER-1 and LUSTER-2 studies did not meet the clinical threshold of efficacy for either of the two doses of the drug over a period of 52 weeks.
“The totality of these results do not support further development of fevipiprant in asthma,” the company said in a statement on 16 December.
