Selected Articles
1. Elecoglipron, an oral small molecule GLP-1 receptor agonist in adults with type 2 diabetes (SOLSTICE): a multicentre, phase 2b, randomised, placebo-controlled trial.
In a multicentre phase 2b RCT (n=404 treated), once-daily oral elecoglipron produced clinically meaningful glycaemic reductions with a safety/tolerability profile consistent with GLP-1 receptor agonists. These findings support advancement to phase 3 for type 2 diabetes treatment.
Impact: Demonstrates efficacy of a once-daily oral small-molecule GLP-1RA—potentially transforming access and adherence compared with injectables or peptide-based oral formulations.
Clinical Implications: If confirmed in phase 3, elecoglipron could broaden GLP-1RA use to patients averse to injections, simplifying treatment logistics without food/fluid restrictions.
Key Findings
- Randomised, double-blind, placebo-controlled phase 2b trial across nine countries; 404 participants received study drug.
- Once-daily oral elecoglipron achieved glycaemic reductions versus placebo.
- Safety and tolerability were consistent with the GLP-1RA class.
Methodological Strengths
- Randomised, double-blind, placebo-controlled multicentre design
- Adequate sample size for phase 2b with international sites
Limitations
- Phase 2b duration and endpoints limit long-term efficacy/safety inference
- Abstract excerpt lacks detailed HbA1c and dose-response data in this summary
Future Directions: Conduct phase 3 trials to confirm durability, cardiovascular/renal outcomes, and head-to-head comparisons with injectable GLP-1RAs and SGLT2 inhibitors.
BACKGROUND: Elecoglipron is an oral, small molecule glucagon-like peptide (GLP)-1 receptor agonist currently in development for the management of type 2 diabetes. Elecoglipron is orally administered once daily with no food or fluid restrictions. SOLSTICE, a phase 2b study, evaluated the efficacy, safety, and tolerability of elecoglipron versus placebo in participants with type 2 diabetes. METHODS: This phase 2b, randomised, double-blind, placebo-controlled trial was conducted in medical research centres and hospitals across nine countries, Canada, Germany, Hungary, Japan, Poland, Slovakia, Spain, the UK, and the USA. Sites were selected based on their capacity to fulfil protocol requirement, including, but not limited to, regulatory and ethics approvals, appropriate infrastructure and personnel, and access to the target patient population. Participants aged 18 years and older with a BMI of 23 kg/m FINDINGS: From Oct 8, 2024, to June 6, 2025, 863 individuals were screened for study inclusion, 457 were excluded as they did not meet the inclusion criteria or met the exclusion criteria, 406 were enrolled and randomly assigned to one of the eight treatment groups, and 404 participants received at least one dose of trial treatment. Among those who received at least one dose of trial treatment, mean (SD) baseline characteristics were: age 58·4 years (10·7); HbA INTERPRETATION: Once-daily oral elecoglipron showed reductions in glycaemia and a safety and tolerability profile consistent with the GLP-1 receptor agonist class at a similar phase of development, supporting continued development with phase 3 trials for people living with type 2 diabetes.

2. Effects of SGLT2 inhibition on incident heart failure in carriers of cardiomyopathy-associated genetic variants.
In DECLARE-TIMI 58 (n=12,685 sequenced), carriers of pathogenic/likely pathogenic cardiomyopathy variants (n=121) experienced a markedly greater reduction in heart-failure hospitalization with dapagliflozin versus placebo than noncarriers, with large absolute risk reductions and significant treatment-by-genotype interaction. Benefits extended to carriers without prior HF.
Impact: Suggests a precision-prevention role for SGLT2 inhibitors based on cardiomyopathy genetics, potentially informing early initiation strategies in high-risk variant carriers.
Clinical Implications: Genotyping for cardiomyopathy genes could identify T2D patients who derive outsized HF-preventive benefit from dapagliflozin; prospective genotype-guided trials are warranted.
Key Findings
- Carriers of P/LP cardiomyopathy variants (n=121 of 12,685) had greater HHF risk reduction with dapagliflozin (HR 0.18) than noncarriers (HR 0.70); Pinteraction=0.03.
- Absolute HHF risk reduction was 13.0% in carriers vs 1.0% in noncarriers; effect persisted in carriers without prior HF.
- Median follow-up was 4.2 years in a high cardiovascular-risk T2D cohort.
Methodological Strengths
- Large randomized trial dataset with adjudicated outcomes and whole-exome sequencing
- Pre-specified high-confidence gene set and formal interaction testing
Limitations
- Genetic subgroup analysis with small carrier numbers limits precision
- Post hoc nature within an RCT; findings need confirmation in prospective genotype-guided trials
Future Directions: Prospective trials to test early SGLT2i initiation in variant carriers, mechanistic studies linking genotype to SGLT2i responsiveness, and health-economic evaluations of genotype-guided care.
Although the beneficial effects of sodium-glucose cotransporter 2 (SGLT2) inhibition in heart failure (HF) have been well established, it is unknown whether SGLT2 inhibition confers benefit in carriers of rare variants in cardiomyopathy-associated genes. Here we evaluated whole-exome sequencing data from the randomized DECLARE-TIMI 58 trial, in which adults with type 2 diabetes and increased cardiovascular risk were randomized to dapagliflozin or placebo treatment. Pathogenic or likely pathogenic variants (P/LP) in high-confidence cardiomyopathy genes were identified, and treatment effects on hospitalization for HF (HHF) were compared between carriers of such variants and noncarriers. Among 12,685 patients for whom sequence data were obtained, 121 carried a cardiomyopathy variant (76 dilated cardiomyopathy, 25 hypertrophic cardiomyopathy and 25 arrhythmogenic cardiomyopathy). Over a median follow-up of 4.2 years, dapagliflozin lowered the risk of HHF more strongly in carriers (hazard ratio 0.18, 95% confidence interval 0.04-0.86) than in noncarriers (hazard ratio 0.70, 95% confidence interval 0.57-0.86; P interaction 0.03). Absolute risk reduction was 13.0% in carriers and 1.0% in noncarriers (P interaction 0.03). Most carriers (82%) had no prior HF, and in carriers without prior HF, treatment with dapagliflozin reduced the absolute risk of HHF by 12.8%, compared with a reduction of 0.6% in noncarriers (P interaction 0.01). The findings from this cohort of older and high-risk patients raise the possibility that SGLT2 inhibitor treatment should be started early to prevent HF in individuals who carry P/LP cardiomyopathy variants. These results need to be confirmed in a prospective, dedicated trial of preventive HF treatments in carriers of P/LP cardiomyopathy-associated variants.
3. Vertical Sleeve Gastrectomy Versus Comprehensive Lifestyle Intervention for Adolescents With Metabolic Dysfunction-Associated Steatotic Liver Disease: A Prospective Controlled Cohort Study.
In a single-centre prospective controlled cohort of adolescents with biopsy-proven MASLD (n=42), vertical sleeve gastrectomy yielded significantly higher 52-week rates of NAS improvement, fibrosis regression, and complete MASLD resolution versus intensive lifestyle therapy, alongside superior weight, ALT, and MRI-PDFF reductions.
Impact: Provides rare prospective histology-based evidence in adolescents, indicating bariatric surgery may modify disease activity and fibrosis beyond lifestyle therapy.
Clinical Implications: For adolescents with severe obesity and biopsy-proven MASLD, VSG should be considered when lifestyle therapy fails, with shared decision-making around surgical risks and long-term follow-up.
Key Findings
- VSG increased the probability of 52-week NAS improvement (RD 0.68), fibrosis improvement (RD 0.36), and complete MASLD resolution (RD 0.49) versus lifestyle.
- Greater reductions with VSG in weight (-19.6%), BMI 95th-percentile percentage (-27.6%), ALT (-54 U/L), and MRI-PDFF (-8.0%).
- Findings were consistent across adjusted analyses and conservative ITT analogues.
Methodological Strengths
- Prospective parallel-arm design with biopsy-confirmed endpoints and advanced imaging (MRI-PDFF, MRE)
- Overlap-weighted adjusted analyses to address baseline imbalances and conservative ITT analogues
Limitations
- Single-centre, non-randomised design with modest sample size; only 64% completed paired histology
- Short-term (52-week) outcomes; durability and safety beyond 1 year remain to be established
Future Directions: Randomised multicentre trials comparing bariatric procedures versus optimized medical/lifestyle care in adolescents, with longer-term histology, metabolic, and safety outcomes.
BACKGROUND: Adolescents with severe obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) lack prospective comparative evidence to select between bariatric surgery and intensive lifestyle intervention. AIMS: To compare 52-week histological and cardiometabolic outcomes of vertical sleeve gastrectomy (VSG) versus comprehensive lifestyle intervention (CLI). METHODS: Single-centre, prospective, parallel-arm study of adolescents aged 12-19 with severe obesity and biopsy-confirmed MASLD with NAFLD Activity Score (NAS) ≥ 3. The primary endpoint was NAS ≥ 2-point decrease without fibrosis worsening; secondary endpoints included MASH resolution, fibrosis regression, MRI proton density fat fraction (MRI-PDFF) and elastography (MRE). Overlap-weighted adjusted analysis addressed baseline imbalance. Conservative unadjusted intention-to-treat analogue analyses treated missing Week 52 histology as nonresponse and missing continuous outcomes as no change. RESULTS: Forty-two adolescents enrolled (VSG = 17; CLI = 25) and 27 (64%) completed paired Week 52 histology. In the adjusted analysis, VSG was associated with a higher probability of NAS improvement (risk difference [RD] 0.68, 95% CI 0.45-0.91), fibrosis improvement (RD 0.36, 95% CI 0.12-0.59) and complete MASLD resolution (RD 0.49, 95% CI 0.26-0.72) when compared to CLI. VSG produced greater reductions in percent weight (-19.6%, 95% CI -30.0 to -9.1), percentage of the 95th percentile BMI (-27.6%, 95% CI -42.6 to -12.7), ALT (-54.0 U/L, 95% CI -80.8 to -27.1) and MRI-PDFF (-8.0%, 95% CI -13.0 to -2.9). Findings were directionally consistent in conservative unadjusted intention-to-treat and paired-biopsy completer analyses. CONCLUSION: In this prospective cohort of adolescents with severe obesity and biopsy-confirmed MASLD, VSG achieved greater 52-week histological improvement, including steatosis and fibrosis, than CLI.
