Johnson & Johnson<\/strong> (J&J, NYSE: JNJ<\/a>) announced FDA marketing approval<\/strong> for Icotyde (icotrokinra)<\/strong>, an interleukin-23 (IL-23) receptor antagonist<\/strong> for moderate-to-severe plaque psoriasis<\/strong> in adults and pediatric patients aged 12+ (\u226540 kg)<\/strong>. The approval establishes Icotyde as the world’s first and only targeted oral peptide<\/strong> that precisely blocks the IL-23 receptor, offering a convenient oral alternative<\/strong> to injectable biologics in the $15+ billion global psoriasis market<\/strong>.<\/p>\n\n\n\n
