Momentum

Some recent activity, at a steady rate.

Runway (estimate)

—unknown

No disclosed raise on file, so there is nothing to model from.

Stage

Phase I

The furthest-along thing in the public record. Not a projection.

Runway is an estimate: the last disclosed raise (SEC Form D) minus a modeled burn rate for the company’s stage and therapeutic area. It is not a disclosure, and companies routinely raise non-dilutive money we can’t see. How this is calculated.

Last disclosed raise

No Form D is on file, so there is no raise to model a runway from. That is why the runway reads “—” rather than a number. It does not mean the company has no money: grants, revenue and notes below the Form D threshold are all invisible here.

Something wrong on this page? The crosswalk is a judgment and we would rather hear it. Report a bad link.
