There are actually a total of four phases.... the good news is that Phase 1 typically takes 1 year.... the bad news is that Phase 2 can go on for 2 more years and Phase 3 can take an additional 3 years.... see the attached link for a bit more detail. If things were to go very well during early phases, sometimes the FDA approves "Fast Trak" for some drugs that speeds up the approval process (google: "Pritelivir" and FDA approval process). https://www.medicinenet.com/script/main/art.asp?articlekey=9877
Amen to that, Laguna! I looked into the information available regarding the research being done by Dr. Friedman at Univ. of Pennsylvania and it was enough to prompt me to donate! Fingers crossed on this one.
