Brief summary
Low back pain is the leading cause of disability in the United States, and obesity is a major risk factor for its development. GLP-1 receptor agonists such as Semaglutide have emerged as effective weight loss agents that may also reduce chronic pain through weight reduction and other mechanisms. This randomized, double-blind, placebo-controlled trial will enroll 250 adults with chronic low back pain and obesity, randomized 1:1 to weekly Semaglutide 2.4 mg or placebo for 52 weeks. The primary outcome is change in low back pain severity, with secondary outcomes including pain-related disability and quality of life.
Interventions
Semaglutide 3.0 mg/mL solution for subcutaneous injection, administered using a 3 mL PDS290 pen-injector. Administered subcutaneously once weekly on the same day each week, without regard to meals. Dose escalation: 0.24 mg weekly for 28 days, then increased to 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg every 4 weeks to reach the maintenance dose of 2.4 mg. The pen uses a drum scale of 1-80 (in increments of 1); corresponding dose counter values are: 0.24 mg = 8, 0.5 mg = 17, 1.0 mg = 34, 1.7 mg = 57, 2.4 mg = 80. Treatment duration is 52 weeks.
Matching placebo solution for subcutaneous injection, administered using a 3 mL PDS290 pen-injector. Administered subcutaneously once weekly on the same day each week, without regard to meals, following the same escalating dose counter schedule as the active comparator (counter values: 8, 17, 34, 57, 80 every 4 weeks). Treatment duration is 52 weeks.

Eligibility
Inclusion criteria
* Ability to provide informed consent before any trial-related activities * Age: 18-85 years * Chronic low back pain, defined as an average low back pain severity of at least 4/10 present on most days for 3 months or longer. * BMI: 30-49 kg/m2
Exclusion criteria
* Known or suspected allergy to trial medication(s), excipients, or related products * Contraindications to study medication(s), worded specifically as stated in the product's Prescribing Information * Previous randomization in this trial * Pregnant, breastfeeding, or the intention of becoming pregnant or not using adequate contraceptive measures * Low back pain related to infection, trauma, or malignancy * Plans to undergo new back pain interventions within 3 months. * Considering or have been offered surgery to treat structural disease believed to cause their low back pain, including infection, severe degeneration adjacent to a prior fusion, mobile spondylolisthesis, severe central lumbar stenosis, coronal or sagittal deformity, or other severe structural pathology diagnosed by a board-certified spine surgeon.
