- Limitations and caveats
The IDMC reported a trend toward significance for URG101; but it was determined that \>300 subjects would be required to reach significance. The data showed inconsistencies between different sites that could affect the ability to pool the data and could not be explained in a blinded analysis. Therefore, at 92 subjects enrolled, the study was terminated early due to data inconsistent with the experimental plan, lack of funding. There is no SAP. Results are limited to primary endpoint and safety.

Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Average of Bladder Sum of Pain Intensity Differences From Baseline to 12 Hours (SPID-12) as Determined Using an 11-point Numeric Rating Scale (NRS) for Pain Intensity | 12 hours | A calculation of average bladder Sum of Pain Intensity Differences from Baseline to 12 hours (SPID-12). A pain intensity score of 0 (no pain) to 10 (worst possible pain) is obtained before starting the study and throughout the 12 hour time period. The average SPID-12 is calculated by multiplying the Pain Intensity Difference score at each time point by the duration since the preceding time point and then summing these values over the specific time period. A lower, negative average SPID-12 difference is better and indicates a reduction in pain intensity compared to the baseline score, whereas a positive score indicates an increase in pain intensity compared to baseline. The full range of results of the average SPID-12 difference could be -119 to +59. |
| Primary | Change of Bladder Sum of Pain Intensity Differences From Baseline to 12 Hours (SPID-12) as Determined Using an 11-point Numeric Rating Scale (NRS) for Pain Intensity | 12 hours | A calculation of bladder Sum of Pain Intensity Differences from Baseline to 12 hours (SPID-12) after administration of URG101 compared with the SPID-12 after administration of lidocaine alone, heparin alone, and placebo. A pain intensity score of 0 (no pain) to 10 (worst possible pain) is obtained before starting the study and throughout the 12 hour time period. A negative value indicates lower SPID-12 values for URG101. The full range of results of the average SPID-12 difference could be -119 to +59. |
