COVID-19 Clinical Trial
— ACOVACTOfficial title:
A Multicenter, Randomized, Active Controlled, Open Label, Platform Trial on the Efficacy and Safety of Experimental Therapeutics for Patients With COVID-19 (Caused by Infection With Severe Acute Respiratory Syndrome Coronavirus-2)
The Austrian Coronavirus Adaptive Clinical Trial (ACOVACT) is a randomized, controlled, multicenter, open-label basket trial that aims to compare various antiviral treatments for COVID-19. Moreover three substudies have been integrated. Currently, patients will be randomized to receive (hydroxy-)chloroquine (Treatment stopped after reports of safety issues), lopinavir/ritonavir, remdesivir or standard of care. Moreover, these patients are eligible for substudy A (randomized to rivaroxaban 5mg 1-0-1 vs. standard of care), substudy B (renin-angiotensin (RAS) blockade vs. no RAS blockade for patients with blood pressure >120/80mmHg), and substudy C (asunercept vs standard of care, pentglobin vs. standard of care for patients with respiratory deterioration and high inflammatory biomarkers). Endpoints were chosen based on the master protocol published by the World Health Organisation and include a 7-point scale of clinical performance, mortality, oxygen requirement (both dose and type), duration of hospitalization, viral load and safety.

Primary | sustained improvement (>48h) of one point on the WHO Scale | The primary endpoint is time to clinical improvement which is defined as time from randomization to an (sustained) improvement of at least one category on two consecutive days compared to the status at randomization measured on a seven-category ordinal scale (proposed by WHO).
The 7-categories of the World Health Organization proposed scale, as follows: Not hospitalized, no limitations on activities Not hospitalized, limitation on activities; Hospitalized, not requiring supplemental oxygen; Hospitalized, requiring supplemental oxygen; Hospitalized, on non-invasive ventilation or high flow oxygen devices; Hospitalized, on invasive mechanical ventilation or ECMO; Death. During hospitalization this score will be determined daily (till day 29). If a patient is released from the hospital before day 29, the score will be determined at day 11 and 29 after randomization (depending when the patient was released or by telephone call). |
