Trial Outcomes & Findings for Ketorolac Versus Ibuprofen to Treat Painful Episodes of Sickle Cell Disease (NCT NCT00115336)

NCT ID: NCT00115336

Last Updated: 2020-10-08

Results Overview

The primary endpoint is the time to a 50% reduction in reported pain intensity. This endpoint is relative to the baseline pain intensity rating on the Oucher scale (minimum 0, maximum 10; higher scores indicate greater pain). The endpoint will be reached when the reported pain intensity is at least one-half of the baseline value on two consecutive measurements at least 4 hours apart. The time ascribed to the endpoint will be the time of the second of these two consecutive pain scales. Participants who do not have a 50% reduction in reported pain intensity, as defined above, before discharge from the hospital will be censored at the time of last rating on the Oucher pain scale before discharge from the hospital

Participant Flow

Planned enrollment for the trial was 120 subjects. Accrual was extremely slow; only 10 participants were randomized before the trial was closed in 2008 due to lack of accrual. Less than 10% of planned enrollment was achieved.

PRIMARY outcome

Timeframe: Measured every 4 hours during hospitalization, over a mean hospitalization duration of 81.5 hours.

Population: One participant was randomized but was discharged (unexpectedly early) from the hospital before study drug was administered. Thus, no primary or secondary outcome data are available for this one participant.

SECONDARY outcome

Timeframe: The duration of the entire hospitalization, over a mean hospitalization duration of 81.5 hours.

Population: Extremely slow accrual led to the trial closing in 2008. Because only 10% of planned enrollment was achieved, no analysis of the primary or secondary outcome data was performed because of lack of power and generalizability.
