Mazdutide in obesity and overweight in adults — evidence extract
The Institute's graded assessment of Mazdutide for obesity and overweight in adults, with the contributing trials and the domain-by-domain certainty reasoning.
§1Evidence extract: Obesity and overweight in adults
§1.1Question and anchor outcome
- Population
- Excess adiposity sufficient to impair health, operationalised in the pivotal incretin programmes as a body-mass index of 30 kg/m² or above, or 27 kg/m² or above with at least one weight-related comorbidity.
- Intervention
- Mazdutide, subcutaneous once weekly
- Comparator
- As used in each contributing trial; reported per trial rather than pooled across comparator types
- Anchor outcome
- Percentage change in body weight from baseline
Additional outcomes the Institute extracts for this indication: Proportion achieving ≥5 %, ≥10 %, ≥15 % and ≥20 % weight reduction; Change in waist circumference; Change in systolic blood pressure; Change in high-sensitivity C-reactive protein.
§1.2Contributing trials
Table 1. Trials contributing to the assessment of Mazdutide in obesity and overweight in adults.
| Trial | Phase | Design | Randomised | Duration | Year |
|---|---|---|---|---|---|
| GLORY-1 | 3 | Randomised, double-blind, placebo-controlled | 610 | 48 weeks | 2025 |
| DREAMS-1 | 3 | Randomised, double-blind, placebo-controlled | 319 | 24 weeks | 2024 |
| MAZ-PH2-OBESITY | 2 | Randomised, double-blind, placebo-controlled | 248 | 24 weeks | 2023 |
§1.3Certainty assessment
Table 2. Reasoning recorded against each certainty domain.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of bias | No concern | No serious concern identified in this domain. |
| Inconsistency | No concern | No serious concern identified in this domain. |
| Indirectness | No concern | No serious concern identified in this domain. |
| Imprecision | No concern | No serious concern identified in this domain. |
| Publication bias | Serious | The evidence base is small, recent and wholly sponsor-generated. |
| Overall rating: Moderate certainty. The true effect is likely to be close to the estimate, but there is a possibility that it is substantially different. Further research is likely to have an important impact on confidence in the estimate. | ||
