I'm thinking about investing in Resverlogix Corp., because their stock just fell from 4,79$ to 3,16$ in the last month. It rose to that price regarding the offering of units of the company and fell again afterwardsBut what does that offering mean for a company going forward?

I started paying attention to it for about 9 month ago, when it was announced, that they started Phase 3 of their, and on 18/4 it was announced that they "successfully reached its targeted 250 MACE events" in the phase 3 trial.I have no idea what that means and how many phases, there are in a drug trial, and I would ask, if anybody with some knowledge would be able to dum it down for me. I hope, that you can help a young clueless invester
