Frequently asked questions about AZD3152

What is AZD3152?

AZD3152 is an investigational small molecule developed by AstraZeneca PLC for COVID-19 and SARS-CoV-2. It is being studied for prevention or treatment in adults at high risk of severe COVID-19, including those with conditions that may reduce vaccine response. It has been tested in Phase 1 and Phase 2 clinical trials.

What is AZD3152 used for in COVID-19?

AZD3152 is being developed for COVID-19 and SARS-CoV-2, specifically for adults with conditions that increase the risk of inadequate protective immune response after vaccination and thus are at high risk of developing severe COVID-19. It is not yet approved and remains investigational.

Who makes AZD3152?

AZD3152 is developed by AstraZeneca PLC, which trades under the ticker AZN. AstraZeneca is the sponsor of the clinical trials evaluating AZD3152 for COVID-19 and SARS-CoV-2.

What phase is AZD3152 in?

AZD3152 has been studied in Phase 1 and Phase 2 clinical trials. The Phase 1 trials are completed, and a Phase 2 trial in adults at high risk of severe COVID-19 is also completed. It is an investigational drug and has not been approved by the FDA.

What clinical trials is AZD3152 in?

AZD3152 has been evaluated in three completed trials: NCT06057064, a Phase 2 study in adults at high risk of severe COVID-19; NCT05932641, a Phase 1 study in healthy Japanese adults; and NCT05872958, a Phase 1 dose exploration study in healthy volunteers. All trials are completed.

Is AZD3152 the same as AZD3152 (Cohort 1) or Biological: AZD3152?

Yes, AZD3152 is also referred to as AZD3152 (Cohort 1), AZD3152 (Parent study Main Cohort), and Biological: AZD3152. These alternative names refer to the same investigational drug developed by AstraZeneca for COVID-19 and SARS-CoV-2.
