Can This Stock Double Again in 2026?

Core Insights - Structure Therapeutics (NASDAQ: GPCR) ended 2025 positively, with shares rising significantly in December following strong mid-stage data for its weight loss drug, aleniglipron. The company aims to maintain this momentum into 2026 as it progresses in the anti-obesity market [1][7]. Pipeline Overview - Aleniglipron is a once-daily oral GLP-1 candidate that demonstrated a placebo-adjusted mean weight loss of 11.3% at the highest dose in a 36-week phase 2b study. An ongoing mid-stage study has shown even higher mean weight loss of up to 15.3% after 36 weeks. The discontinuation rate due to adverse reactions was 10.4% in the first study, which is typical for GLP-1 medications [4][5]. - Structure Therapeutics plans to initiate a phase 3 study for aleniglipron this year. Additionally, the company has other candidates in its pipeline, including ACCG-2671, an oral weight loss candidate that mimics the action of the amylin hormone [5]. Market Competition - Aleniglipron faces competition from at least two other oral weight loss medications expected to be approved by the time it reaches the market. The FDA has recently approved an oral formulation of Wegovy and is reviewing orforglipron, another oral medicine developed by Eli Lilly [6][7].
