ACTIV-3: Therapeutics for Inpatients With COVID-19 (TICO)

August 23, 2023 updated by: National Institute of Allergy and Infectious Diseases (NIAID)

A Multicenter, Adaptive, Randomized, Blinded Controlled Trial of the Safety and Efficacy of Investigational Therapeutics for Hospitalized Patients With COVID-19

This study looks at the safety and effectiveness of different drugs in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either a study drug plus current standard of care (SOC), or with placebo plus current SOC.

Detailed Description

This is a master protocol to evaluate the safety and efficacy of multiple investigational agents aimed at modifying the host immune response to SARS-CoV-2 infection, or directly enhancing viral control in order to limit disease progression.

The protocol is for a randomized, blinded, controlled platform study that allows investigational drugs to be added and dropped during the course of the study. This allows for efficient testing of new drugs against placebo and standard of care (SOC) treatment within the same study. When more than one drug is being tested at the same time, participants will be randomly allocated to treatments or placebo.

Randomization will be stratified by study site pharmacy and disease severity. There are 2 disease severity strata: Participants without organ failure (severity stratum 1); and participants with organ failure (severity stratum 2).

An independent Data and Safety Monitoring Board (DSMB) will regularly review interim analyses and summarize safety and efficacy outcomes. For investigational drugs with minimal pre-existing safety knowledge, the pace of enrollment with be initially restricted, and there will be an early review of safety data by the DSMB. For the study of each agent, at the outset of the trial, only participants in disease severity stratum 1 will be enrolled. This will continue until approximately 300 participants are enrolled and followed for 5 days. The exact number will vary according to the speed of enrollment and the timing of DSMB meetings. Prior to expanding enrollment to also include patients in disease severity stratum 2, safety will be evaluated and a pre-specified futility assessment by the DSMB will be carried out using 2 ordinal outcomes assessed at Day 5.

Both ordinal outcomes are used to assess futility because it is currently unclear whether the investigational agents under study will primarily influence non-pulmonary outcomes, for which risk is increased with SARS-CoV-2 infection, in part, through mechanisms that may be different from those that influence pulmonary outcomes.

For investigational agents passing this futility assessment, enrollment of participants will be expanded, seamlessly and without any data unblinding, to include participants in disease severity stratum 2 as well as those in disease severity stratum 1. Future interim analyses will be based on the primary endpoint of sustained recovery and will use pre-specified guidelines to determine early evidence of benefit, harm or futility for the investigational agent. Participants will be followed for 18 months following randomization.

The international trials within this protocol will be conducted in several hundred clinical sites. Participating sites are affiliated with networks funded by the United States National Institutes of Health (NIH) and the US Department of Veterans Affairs.

2. ECMO (extracorporeal membrane oxygenation)
3. Mechanical circulatory support
4. vasopressor therapy
5. commencement of renal replacement therapy at this admission (i.e. not patients on chronic renal replacement therapy).
Participants with moderate to severe hepatic impairment (i.e. Child-Pugh class B or C) or acute liver failure (PF-07304814 investigational agent).
Participants receiving any medications or substances that are strong inhibitors or inducers of cytochrome P450 (CYP) 3A4 (PF-07304814 investigational agent).
Patients will be excluded if taking drugs which have a narrow therapeutic window that are substrates of CYP3A4, including but not limited to: astemizole, cisapride, cyclosporine, dihydroergotamine, ergotamine, pimozide, quinidine, sirolimus, tacrolimus, and terfenadine (PF-07304814 investigational agent).
Patients with a history of deep vein thrombosis or pulmonary thrombotic embolism (Prior to initial futility assessment of PF-07304814 investigational agent).

Number of Arms

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: ACTIV-3 Drug plus SOC Participants in this study will be randomized to receive one of the ACTIV-3 drug treatments plus Standard of Care (SOC) or placebo plus SOC	Biological: LY3819253 Participants are no longer being randomized to this intervention. Biological: Remdesivir Provided to all study participants as SOC unless contraindicated for an individual patient. Biological: VIR-7831 Participants are no longer being randomized to this intervention. Biological: BRII-196/BRII-198 Participants are no longer being randomized to this intervention. Biological: AZD7442 Participants are no longer being randomized to this intervention. Other Names: AZD8895 + AZD1061 Drug: MP0420 Participants are no longer being randomized to this intervention. Other Names: ensovibep Drug: PF-07304814 250 mg per day for 5 days. Administered as a constant rate intravenous infusion. Suspended: Participants are not currently being randomized to this intervention.
Placebo Comparator: Placebo plus SOC The placebo arm may be pooled across more than one experimental arm if multiple investigational drugs are available to be tested at the same time. If it is not possible to use matching placebo over more than one experimental arm, additional placebo arms will be included in the study	Biological: Remdesivir Provided to all study participants as SOC unless contraindicated for an individual patient. Drug: Placebo Commercially available 0.9% sodium chloride solution. Administered by IV infusion
