The investor was also issued milestone-based Series A, Series B, and Series C common warrants, exercisable upon the company's achievement of certain targets. Proceeds from warrant redemptions would be an additional $17.5 million.

What Milestones Is DCOY Targeting?

The company will be able to receive an additional $3.5 million in funding from Series A warrants, when exercised, once it applies to begin Phase 1 trials in Europe. It will receive $7 million from Series B warrants once the U.K. health regulator greenlights its Phase 2a human challenge trial, and another $7 million from Series C warrants if the early-stage U.K. trial is successful.

According to the company, it is focused on Designable Multi-Antivirals (D-MAVs), which aim to enable a single drug to work against multiple viral threats, to evolve from the traditional one-virus, one-drug model.
