On May 12, 2020, Moderna announced the U.S. Food and Drug Administration (FDA had granted Fast Track designation for the Company’s mRNA vaccine candidate (mRNA-1273) against the novel coronavirus (SARS-CoV-2).

The Company intended to enroll 600 healthy participants across two cohorts of adults ages 18-55 years (n=300) and older adults ages 55 years and above (n=300). Each participant was assigned to receive placebo, a 50 ﾵg or a 250 ﾵg dose at both vaccinations. Participants were followed through 12 months after the second vaccination.

Fast Track is designed to facilitate the development and expedite the review of therapies and vaccines for serious conditions and fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communication with the FDA, in addition to a rolling submission of the marketing application. The Company previously received Fast Track designation for its investigational Zika vaccine (mRNA-1893) and its methylmalonic acidemia (MMA; mRNA-3704) and propionic acidemia (PA; mRNA-3927) programs.

On May 6, the U.S. Food and Drug Administration (FDA) completed its review of the Company’s investigational New Drug (IND) application for mRNA-1273 allowing it to proceed to a Phase 2 study, which is expected to begin shortly. Moderna is finalizing the protocol for a Phase 3 study, expected to begin in early summer of 2020. Funding from the Biomedical Advanced Research and Development Authority (BARDA), a division of the Office of the Assistant Secretary for Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS), supported the planning for these studies and will also support the late-stage clinical development programs, as well as the scale-up of mRNA-1273 manufacturing both at the Company’s facilities and that of its strategic collaborator, Lonza Ltd.

Moderna has received initial feedback from the FDA on the design of the planned Phase 2 study, which will evaluate the safety, reactogenicity and immunogenicity of two vaccinations of mRNA-1273 given 28 days apart. The Company intends to enroll 600 healthy participants across two cohorts of adults ages 18-55 years (n=300) and older adults ages 55 years and above (n=300). Each participant will be assigned to receive placebo, a 50 μg or a 250 μg dose at both vaccinations. Participants will be followed through 12 months after the second vaccination.
