Novartis (NVS) said Thursday results of a phase 3 trial of Rhapsido showed sustained efficacy through 52 weeks in adult patients across three subtypes of chronic inducible urticaria.
The company said patients who switched from placebo to Rhapsido at week 24 had response rates at week 52 similar to those who received the drug from the start.
The complete or partial response rates at week 52 in patients receiving Rhapsido were 46.8%, 83.3% and 58.2% in the symptomatic dermographism, cold urticaria and cholinergic urticaria cohorts, respectively, compared with 47.7%, 88.9% and 69.8% in patients who switched to Rhapsido from placebo, according to a statement.
Rhapsido was well tolerated through week 52, with a safety profile consistent with previous studies, Novartis said.
