GeoVax Advances Toward European Approval for GEO-MVA Mpox Vaccine Following EMA Milestone

GeoVax Labs, Inc., a clinical-stage biotechnology company, has recently highlighted a significant regulatory milestone achieved with the European Medicines Agency (EMA) for its GEO-MVA vaccine targeting Mpox and smallpox. The EMA's positive Scientific Advice suggests that a single Phase 3 immuno-bridging trial could suffice for a Marketing Authorization Application (MAA) under the EU's centralized procedure, bypassing the need for Phase 1 and 2 studies. This development not only reduces the development risk and timelines but also positions GeoVax for earlier product commercialization and revenue generation in one of the world's largest vaccine markets.

The immuno-bridging approach, accepted by regulatory authorities, allows for vaccine approval based on the immune response comparable to an already approved vaccine, thereby reducing the need for large-scale efficacy trials. David Dodd, Chairman and CEO of GeoVax, emphasized the strategic and commercial significance of this EMA guidance, stating it represents a potential commercial inflection point for the company. With the Phase 3 trial in operational preparation, GeoVax is entering a phase of potential revenue acceleration, supported by growing global demand and regulatory momentum.

Key highlights from the investor perspective include an expedited approval path confirmed by the EMA, de-risked development by moving directly to a Phase 3 trial, and a market timing advantage coinciding with the WHO's fourth Mpox Public Health Emergency of International Concern (PHEIC) declaration. Additionally, GEO-MVA could become the only MVA-based Mpox vaccine alternative to Bavarian Nordic's Imvanex/Imvamune, addressing global supply constraints. GeoVax expects to initiate its Phase 3 trial in the second half of 2026, with current manufacturing readiness supporting near-term supply and a transition to a more scalable production method underway.

GeoVax is actively engaging with European regulatory bodies and public health stakeholders to advance GEO-MVA access and funding partnerships. This EMA development potentially shortens GeoVax's path to revenue generation and enhances its strategic value, transitioning the company from a development-stage biotech to a viable near-term commercial vaccine entity.
