§2Design and population
§2.1Design and allocation
- Design class
- Randomised, double-blind, placebo-controlled, parallel-group
- Masking
- Double-blind (participant, investigator and sponsor)
- Arms
- 3
- Allocation
- Randomised across dose arms and a common 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 |
|---|---|---|---|
| Thymosin beta-4, dose level 1 | 25 | 34.7 % | Randomised dose arm |
| Thymosin beta-4, dose level 2 | 22 | 30.6 % | Randomised dose arm |
| Placebo | 25 | 34.7 % | Matched placebo |
| Randomised total 72 as published. Arm-level splits are reconstructed and are not published figures. | |||
§2.3Population
Indication. Cutaneous wound healing and tissue repair
Restoration of epithelial and dermal integrity following injury, assessed by closure rate, area reduction and scar quality.
Geographic footprint. Sweden · Poland · Republic of Korea · Mexico.
§2.4Eligibility as the Institute reads it
- Included. Restoration of epithelial and dermal integrity following injury, assessed by closure rate, area reduction and scar quality.
- Excluded. Participants for whom the intervention is contraindicated, including not established — no marketing authorisation. 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.
