BACKGROUND: A small-molecule injectable drug, CBL-514, has shown promising efficacy and safety for subcutaneous fat reduction.
OBJECTIVES: To further evaluate the efficacy and safety of CBL-514 for abdominal subcutaneous fat reduction.
METHODS: In this single-blind, randomized, parallel-group, placebo-controlled Phase 2 trial, 76 participants were randomized (2:1) to receive up to 4 CBL-514 treatments (2 mg/cm2, maximum 600 mg/treatment) or placebo, administered subcutaneously to the abdomen every 4 weeks. Two follow-up visits were conducted at 4 and 8 weeks following final treatment. Changes in abdominal subcutaneous fat thickness and volume were measured by ultrasound. The primary endpoint was the proportion of participants with subcutaneous fat volume loss of ≥150 mL from baseline compared with placebo.
RESULTS: In the intention-to-treat population, a significantly higher proportion of CBL-514-treated participants achieved ≥150 mL subcutaneous fat volume reduction from baseline compared with placebo-treated participants at both follow-up visits. At 8 weeks post final treatment, 69.6% of CBL-514-treated participants lost ≥150 mL subcutaneous fat, compared with none in the placebo group (P < .001). Moreover, 60.9% of participants in the CBL-514 group further achieved the ≥200 mL subcutaneous fat loss threshold. Of the 28 participants in CBL-514 group (n = 50) who lost ≥150 mL subcutaneous fat, 42.9% (12/28 participants) achieved this target after a single treatment. The most common treatment-emergent adverse events were injection site reactions and were of mild-to-moderate severity.
CONCLUSIONS: CBL-514 treatment significantly reduced abdominal subcutaneous fat volume with a favorable safety profile. As a noninvasive treatment, CBL-514 could be a new, promising alternative therapy for effective targeted subcutaneous fat reduction.
