Frequently asked questions about GEO-CM04S1

What is GEO-CM04S1?

GEO-CM04S1 is an investigational vaccine developed by GeoVax Labs, Inc. for protection against COVID-19 infection. It is a synthetic MVA-based SARS-CoV-2 vaccine currently in Phase 2 clinical development. It is being studied in patients with blood cancers, a population that may respond less well to standard COVID-19 vaccines.

What is GEO-CM04S1 used for in COVID-19?

GEO-CM04S1 is being developed to prevent COVID-19 infection, with a focus on patients who have blood cancers such as leukemia, lymphoma, and plasma cell myeloma. These patients often have weakened immune responses to conventional vaccines, so GEO-CM04S1 is being tested as an alternative vaccination strategy.

Who makes GEO-CM04S1?

GEO-CM04S1 is made by GeoVax Labs, Inc., a biotechnology company whose common stock trades under the ticker symbol GOVX. GeoVax is the developer responsible for the vaccine's clinical program.

What phase is GEO-CM04S1 in?

GEO-CM04S1 is in Phase 2 clinical development. It is an investigational vaccine and has not been approved by the FDA. The Phase 2 trial is currently active and not recruiting, with a total of 63 participants enrolled.

What clinical trials is GEO-CM04S1 in?

GEO-CM04S1 is being evaluated in one clinical trial, NCT04977024, titled "SARS-CoV-2 Vaccine (GEO-CM04S1) Versus mRNA SARS-COV-2 Vaccine in Patients With Blood Cancer." This Phase 2 trial has an enrollment of 63 participants and is currently active but not recruiting.

Is GEO-CM04S1 the same as Synthetic MVA-based SARS-CoV-2 Vaccine GEO-CM04S1?

Yes, GEO-CM04S1 is also known as the Synthetic MVA-based SARS-CoV-2 Vaccine GEO-CM04S1. Both names refer to the same investigational vaccine developed by GeoVax Labs, Inc. for COVID-19.
