Trial Outcomes & Findings for ACTIV-6: COVID-19 Study of Repurposed Medications - Arm D (Ivermectin 600) (NCT NCT05894538)

NCT ID: NCT05894538

Last Updated: 2023-11-03

Results Overview

Time to sustained recovery was the number of days between receipt of study drug and the third of 3 consecutive days without symptoms. Participants who died, by definition, did not recover regardless of reported symptom freedom. The reported summary is the median survival time.

Arm D - Ivermectin 600
Ivermectin - 7-mg tablets Participant will be instructed to take a pre-specified number of tablets for 6 consecutive days based on their weight for a daily dose of approximately 400-600 µg/kg. Ivermectin: Each participant will receive a sufficient quantity of 7-mg tablets to be taken as directed based on their weight. The tablets are white, round, biconvex tablets with "123" over the scoring on one side. All packaging will be labeled to indicate that the product is for investigational use.
Arm D - Placebo
Placebo - appearance and size matched to active study drug. Participant will be instructed to take a pre-specified number of tablets for 6 consecutive days based on their weight, matched to active study drug dosing. Placebo: Each study arm will contain a placebo comparator. Placebo will look similar to study drug and will be administered via the same route of administration and dose. However, placebo will be an inactive substance, containing no study drug.

Population: Participants who responded to the quality of life survey at each timepoint.

The PROMIS-29 (Patient-Reported Outcomes Measurement Information System) consists of seven health domains with four 5-level items associated with each and a pain intensity assessment using a 0-10 numeric rank. The seven health domains include physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance. Raw score ranges from 4-20, where a higher score correlates to better outcome for physical function.

Population: Participants who responded to the quality of life survey at each timepoint.

The PROMIS-29 (Patient-Reported Outcomes Measurement Information System) consists of seven health domains with four 5-level items associated with each and a pain intensity assessment using a 0-10 numeric rank. The seven health domains include physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance. Raw score ranges from 4-20 where a lower score correlates to better outcome for anxiety.

Population: Data not collected on 50 participants.

The symptom and clinical event scale is a daily measurement that combines the global symptom burden scale with clinical events hospitalization and mortality. (No symptoms, mild symptoms, moderate symptoms, severe symptoms, hospitalized, deceased). Time unwell was the portion of follow-up (in days) that a participant was symptomatic, hospitalized, or deceased. The quantity is estimated from a Bayesian longitudinal ordinal regression model with covariate adjustment and weakly informative priors. Measure of dispersion is 95% credible interval.

The symptom and clinical event scale is a daily measurement that combines the global symptom burden scale with clinical events hospitalization and mortality. (No symptoms, mild symptoms, moderate symptoms, severe symptoms, hospitalized, deceased). The cumulative benefit of treatment A is the probability of experiencing a better outcome on treatment A compared to treatment B, summed over the days of follow-up. The difference between the cumulative benefit of treatment A and the cumulative benefit of treatment B is known as the difference in days benefit. Measure of dispersion is 95% credible interval.
