- Ligelizumab, a high-affinity anti-IgE antibody, demonstrated superiority compared with placebo at Week 12 in Phase III PEARL 1 and PEARL 2 trials, but not versus omalizumab1
- Novartis is continuing to evaluate the PEARL data and will provide an update in due course as well as next steps for the program
BASEL, Switzerland I December 20, 2021 I Novartis today announced top-line results from PEARL 1 and PEARL 2 Phase III studies in chronic spontaneous urticaria (CSU), which showed that the studies met their primary endpoints of superiority for ligelizumab versus placebo at Week 12, but not versus omalizumab1.
“We are disappointed that we have been unable to demonstrate superior efficacy for ligelizumab versus standard of care in the treatment of CSU,” said John Tsai, M.D., Head of Global Drug Development and Chief Medical Officer, Novartis. “We will continue to evaluate the potential for ligelizumab to bring benefit to patients in the areas of chronic inducible urticaria (CIndU) and food allergy, where there is significant unmet need.”
Full PEARL 1 and 2 Phase III data will be made publicly available after study completion in the second half of 2022.
CSU is an unpredictable, systemic skin disease, characterized by the spontaneous and recurrent appearance of itchy, painful hives (wheals) on the skin, angioedema or both for at least 6 weeks2,3 and affects up to 1% of the population at any one time2. Approximately 60% of patients do not achieve complete control with first-line treatment antihistamines4-7.
Novartis recently began Phase III studies for remibrutinib (LOU064), a highly selective, potent oral BTK inhibitor that has previously shown rapid and effective CSU disease control8,9.
Novartis in chronic spontaneous urticaria (CSU)
Novartis is dedicated to reimagining the care of patients with diseases that can severely limit quality of life such as CSU, psoriasis, acne and atopic dermatitis. Novartis is committed to developing medicines that will advance the treatment of CSU, so patients are able to live their lives without the distressing and unpredictable symptoms of this debilitating disease10. These include ligelizumab (QGE031) a high-affinity monoclonal anti-immunoglobulin E antibody and remibrutinib (LOU064), a highly selective, potent oral Bruton’s tyrosine kinase (BTK) inhibitor with a potential best-in-class profile for the treatment of autoimmune disorders. Any new therapies will add to our portfolio of medicines that already includes Xolair® (omalizumab), our existing approved therapy for CSU.
About ligelizumab
Ligelizumab (QGE031) is a high-affinity, monoclonal anti-immunoglobulin (Ig) E antibody. In a Phase IIb dose-finding trial, more patients experienced complete resolution of wheals (hives) with ligelizumab compared with Xolair® (omalizumab)11.
About PEARL 1 and PEARL 2
PEARL 1 and PEARL 2 (NCT03580369 and NCT03580356) are two identically designed Phase III, multicenter, randomized, double-blind, active- and placebo-controlled, parallel-group studies12,13. The twin studies are designed to establish efficacy and safety of ligelizumab in adult and adolescent patients (≥12 years of age) with chronic spontaneous urticaria (CSU) who remain symptomatic despite H1-antihistamine treatment by demonstrating better efficacy over placebo and Xolair® (omalizumab)12,13. More than 2,000 adult and adolescent patients across 48 countries were randomized to ligelizumab 72 mg, ligelizumab 120 mg, omalizumab 300 mg or placebo with treatment given every 4 weeks for 1 year12-14. Patients initially randomized to placebo were switched to ligelizumab 120 mg from Week 24 until the end of the 52-week treatment period. The primary outcome measured the change from baseline in Urticaria Activity Score over 7 days (UAS7) at Week 1212-14.
