<bold>Background/Objectives:</bold> Acute upper respiratory tract infections (URTIs) are common illnesses that cause significant discomfort due to symptoms such as fever, headache, sore throat, and muscle pain. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for symptom relief due to their anti-inflammatory, analgesic, and antipyretic properties. Pelubiprofen, a new NSAID, has not been extensively evaluated for its efficacy and safety in treating URTI-related symptoms, particularly fever. This study aimed to demonstrate that pelubiprofen is not inferior to loxoprofen in reducing fever in patients with URTIs. <bold>Methods</bold>: This phase III, multicenter, randomized, double-blind, parallel-group, active-controlled, non-inferiority trial involved 181 adults with URTI-related fever (>= 38.0 degrees C), who were randomly assigned to receive pelubiprofen or loxoprofen at a 1:1 ratio. The primary end point was decreasing axillary temperature 4 h post-dose. Secondary end points included fever reduction, pain relief based on the visual analog scale (VAS), and safety. <bold>Results:</bold> Of the 181 participants, 130 (pelubiprofen [n = 61] and loxoprofen group [n = 69]) underwent randomization. The mean reduction in axillary temperature at 4 h post-dose was comparable between the two groups (-0.08 +/- 0.62 degrees C). The lower bound of the 97.5% one-sided confidence interval was -0.30 degrees C, which is greater than the non-inferiority margin of 0.35 degrees C, demonstrating the non-inferiority of pelubiprofen to loxoprofen. The secondary outcomes showed no significant differences in efficacy or safety (p > 0.05). <bold>Conclusions</bold>: Pelubiprofen is not inferior to loxoprofen in reducing fever associated with URTIs and is a safe and effective treatment option.
