My estimates are $16M - 19M for the trials are required.

I could be wrong but from a risk perspective a CR to fund the trials would ensure capital is available to be allocated to continue normal business operations and focus on growth in other areas. If current cash and future sales are allocated to the funding the trials then on a risk basis It's touch and go.
