The financing will fund manufacturing, testing and regulatory preparations for Phase 2 development.

GPN Vaccines has closed a fully subscribed $10 million private placement with new and existing investors. The company did not name the participants.

The proceeds will support preparations for Phase 2 development of Gamma-PN, its investigational pneumococcal vaccine. Planned work includes cGMP manufacturing, expansion of its antibody-testing laboratory and an Investigational New Drug submission to the US Food and Drug Administration.
