Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | CVA21 | CVA21 was administered by intravesical instillation of one of 3 ascending dose levels or schedules | 1 | 9 | EG000 |
| Group 2 | CVA21/Mitomycin C | Mitomycin C (MMC) was administered at 10 mg by intravesical instillation on Day 1. Four hours after instillation of MMC, CVA21 was administered by intravesical instillation of one of 2 ascending dose levels or schedules. Subjects received a second instillation of CVA21 alone on Day 2 without pretreatment with MMC. | 0 | 6 | EG001 |

Harm
- What it counts
- Total, serious adverse events
- Time frame
- 30 days. The analysis for each dose escalation cohort for CVA21 only was pooled as the numbers were so small. This resulted in an analysis showing 2 arms.
