SURPASS-2 — design and population
Design, allocation, arms and the population enrolled.
§2Design and population
§2.1Design and allocation
- Design class
- Randomised, double-blind, active-controlled, parallel-group
- Masking
- Double-blind (participant and investigator)
- Arms
- 2
- Allocation
- Randomised between the intervention and its comparator
- Endpoint adjudication
- Not applicable to the primary endpoint of this design
- Data monitoring
- As specified in the protocol
§2.2Arms
Table 2. Randomised arms. Illustrative: arm-level allocations are reconstructed by the Institute from the design class and the randomised total where the published report does not state them.
| Arm | Allocated | Share | Description |
|---|---|---|---|
| Tirzepatide | 929 | 49.4 % | Intervention at the dose reached after titration |
| Active comparator | 950 | 50.6 % | Comparator agent at the dose specified in the protocol |
| Randomised total 1,879 as published. Arm-level splits are reconstructed and are not published figures. | |||
§2.3Population
Indication. Type 2 diabetes mellitus
A disorder of glucose regulation characterised by insulin resistance with relative insulin deficiency, diagnosed by glycated haemoglobin, fasting plasma glucose or oral glucose tolerance criteria.
Geographic footprint. United States · Finland · Spain · Czechia · Japan · Taiwan · New Zealand · Mexico · Argentina · India.
§2.4Eligibility as the Institute reads it
- Included. A disorder of glucose regulation characterised by insulin resistance with relative insulin deficiency, diagnosed by glycated haemoglobin, fasting plasma glucose or oral glucose tolerance criteria.
- Excluded. Participants for whom the intervention is contraindicated, including personal or family history of medullary thyroid carcinoma. Exclusion criteria narrow the population to which the estimate applies and are the principal source of indirectness where a trial estimate is applied to ordinary practice.
