This study assesses omalizumab\u2019s efficacy in reducing nasal polyp recurrence, aiming to provide insights into managing CRSwNP and improving patient outcomes through potential therapeutic interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The Iranian clinical trial (IRCT20220218054057N1) approved in January 2023 focused on adult patients (18-60\u2009years) with CRSwNP. Participants were randomized into control and omalizumab groups. Before the intervention, demographic data, Sino-nasal outcome test (SNOT-22), Total nasal symptom score (TNSS), Nasal polyp score (NPS), and blood IgE levels were collected. An oral aspirin challenge diagnosed AERD. Both groups were monitored, completing questionnaires during and 12\u2009months post-study initiation. Recurrence of nasal polyps was examined at the 1-year mark. SPSS version 25 was used for analysis. The trial aimed to assess omalizumab\u2019s impact on CRSwNP, considering various factors and long-term outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      In a study with 76 participants (50 control, 26 omalizumab), aged around 45.62 and 41.50\u2009years, without significant difference in gender and number of polyp surgeries in both groups. Both groups experienced a notable decrease in NPS, with the omalizumab group showing a greater reduction (\u22121.31 vs \u22120.90,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.001). TNSS scores dropped more in the omalizumab group (\u22124.54) than in the control group (\u22122.04) at week 24. SNOT-22 scores decreased significantly from baseline to week 24 for both groups.
