Novartis Gains FDA Approval for Urticaria Drug Rhapsido
The nod from the U.S. regulator positions the oral BTK inhibitor as a new option for millions suffering from chronic hives.
Novartis (NVS) has secured a significant regulatory victory, receiving , a novel treatment for chronic spontaneous urticaria (CSU). The decision marks the arrival of the first oral Bruton's tyrosine kinase (BTK) inhibitor for adult patients who remain symptomatic despite standard H1 antihistamine therapy.
CSU, a condition characterized by the sudden onset of itchy hives and swelling for six weeks or longer, affects approximately 1.7 million people in the United States. For more than half of these patients, first-line antihistamine treatments fail to provide adequate relief, creating a substantial unmet medical need for new therapeutic options. Rhapsido's approval introduces a new mechanism of action in a convenient, twice-daily oral formulation, a significant departure from the injectable biologics that have been the primary alternative.
Wall Street analysts have been quick to recognize the drug's potential, with many viewing Rhapsido as a . The drug's compelling Phase III trial data, which demonstrated rapid symptom reduction and a favorable safety profile, underpins its strong value proposition. The convenience of an oral pill that does not require injections or routine lab monitoring is expected to drive strong patient and physician adoption.
The commercial opportunity for Novartis is substantial. The , and Rhapsido's first-mover advantage as an oral BTK inhibitor positions the company to capture a significant share. The approval not only strengthens Novartis's immunology franchise but also highlights the potential of its pipeline, as remibrutinib is also being investigated for other immune-mediated conditions like hidradenitis suppurativa and food allergies.
