Structure Therapeutics Provides Comprehensive GSBR-1290 Program Update Including Clinically Meaningful Proof-of-Concept Data From Phase 2a Clinical Study (GlobeNewswire) - P1 | N=18 | NCT05893043 | Sponsor: Gasherbrum Bio, Inc | "GSBR-1290 demonstrated a substantial weight reduction in Japanese participants (-3.91% on GSBR-1290 vs -1.67% placebo) and in non-Japanese participants (-5.13% not placebo-adjusted), with no discontinuations or dose reductions, and no SAEs. These data will be used for regulatory interactions in Japan in preparation for potential future global studies of GSBR-1290....Structure has completed 6-month (rodent) and 9-month (non-human primate) toxicology studies to evaluate the safety of GSBR-1290. No major findings were observed in either study, with no test article-related changes observed in the liver, including ALT/AST, at all doses, and a >100 fold safety window at the 120 mg therapeutic dose."

The study demonstrated a statistically significant and clinically meaningful reduction in weight at Week 12 (-3.26% to -3.51%, placebo-adjusted) (Table 3). Weight loss continued to decrease through Week 12."

Structure Therapeutics Provides Comprehensive GSBR-1290 Program Update Including Clinically Meaningful Proof-of-Concept Data From Phase 2a Clinical Study (GlobeNewswire) - "Full 12-week results from the Phase 2a obesity cohort (n=64), including data from the additional 24 participants currently being enrolled, are expected in the second quarter of 2024. Structure plans to initiate a Phase 2b obesity study of GSBR-1290 in the second half of 2024. The study is planned to include at least 275 individuals across the United States and Europe and will include multiple modified dose titration regimens to optimize efficacy and tolerability. An additional Phase 2 study in T2DM is also planned for the second half of 2024 to optimize the efficacy and tolerability of GSBR-1290 in this patient population. The ongoing formulation bridging and titration optimization study is evaluating capsule versus tablet pharmacokinetics (PK) and exploring different titration regimens. This study has completed enrollment (n=54), and data are expected in the second quarter of 2024."
