Evaluate Safety and Effectiveness of MBX-102 in Type 2 Diabetes Patients With Poor Glycemic Control on Metformin

1. Is the biology right?

• Somatic driver evidence: no · None of PPARG, SLC22A12, MT-ND6, NDUFA10, NDUFS8 has somatic-mutation evidence in type 2 diabetes mellitus

  Rule: Open Targets has somatic-mutation evidence for the target in this cancer. Source: Open Targets: PPARG in type 2 diabetes mellitus, 2026-11-11
• Human genetic evidence: yes · PPARG: curated genetic literature, germline; SLC22A12: germline; NDUFA10: germline

  Rule: Any germline or somatic human genetic evidence for the target in this cancer, counted apart from animal-model and literature evidence. Source: Open Targets: PPARG in type 2 diabetes mellitus, 2026-11-11

  Published context: 2.6× relative probability of success, phase 1 to launch, with human genetic support (Minikel et al., Nature 2024, drug programs to 2023). All therapy areas, mostly germline evidence; not a probability for this program.
• Pediatric target: no · Not on the FDA list

  Rule: Target is on FDA's Pediatric Molecular Target List (relevant targets); membership alone neither requires nor waives a study. Source: FDA Pediatric Molecular Target List (Listed as February 2026 on the FDA Pediatric Oncology page; the file served is 9.7.22_the_relevant_molecular_target_list.xlsx, whose Summary of Changes sheet is headed 'SEPTEMBER 2022 UPDATE' (footnote date 2022-09-01)), 2026-11-11
• Haematologic cancer: no · Solid tumour

  Rule: From the indication, or the registry conditions when no indication matches. Source: ClinicalTrials.gov NCT00814372, 2026-11-11

  Published context: Likelihood of approval from phase 1: 7.5% haematologic vs 4.6% solid (BIO / Informa / QLS 2021, 2011–2020). Population-level, not a prediction.

• PPARG (via MBX-102): Evidence types in type 2 diabetes mellitus: clinical, genetic_literature, literature, genetic_association, animal_model; literature and animal_model listed separately from human genetics. Datasources: clinical_precedence, gwas_credible_sets, genomics_england, eva, gene_burden, europepmc, impc. · Open Targets: PPARG in type 2 diabetes mellitus

2. Can the result be trusted?

  Rule: Registry allocation field. Source: ClinicalTrials.gov NCT00814372, 2026-11-11
• Small denominator: no · 242 enrolled; each patient moves a rate by 100 ÷ 242 = 0.4 points

  Rule: Enrolment under 30; the arithmetic is shown, not a benchmark. Source: ClinicalTrials.gov NCT00814372, 2026-11-11
• Primary endpoint is overall survival: no · Change in HbA1c from baseline and compared to placebo

  Rule: A registered primary outcome measure names overall survival. Source: ClinicalTrials.gov NCT00814372, 2026-11-11

  Published context: Non-OS primary endpoint: odds ratio 2.79 for a positive phase 3 (Otsuka 2021, 400 phase 3 oncology trials, to 2020). Shown with the next figure: a surrogate is easier to hit, and often a weak guide to survival.

  Published context: 52% of surrogate-to-OS correlations are low (Prasad 2015, published to 2014). Shown with the figure above.
• Results overdue: yes · Primary completion 2010-02, 201 months ago; no results posted

  Rule: Primary completion (actual) more than 12 months ago and no results posted to the registry. Source: ClinicalTrials.gov NCT00814372, 2026-11-11

  Published context: 40.9% of applicable trials report results within a year (Results-reporting studies summarised in spec §11, all therapy areas). All areas, not oncology only.
