The Nature article started by saying "The 'clubbers' drug' ecstasy may be put to a clinical use.." The use of the term "clinical use" means in this case that clinical (human) research with MDMA (Ecstasy) may soon start, not that MDMA is anywhere close to FDA approval for prescription use, which is another meaning of the term "clinical use."
The article also said that "the team has struggled to find an independent review board that is prepared to monitor the study." The primary role of the IRB is to review, modify if necessary and approve the protocol design before the study starts to ensure that the human rights of the subjects are sufficiently protected. While the IRB does have some oversight responsibilities while the study is in progress, "monitoring" is a technical term that is done by people who are not part of the IRB who ensure that the data is gathered and reported in an accurate manner consistent with the requirements established in the protocol.
Finally, the article said, "they need a permit from the US Drug Enforcement Agency to dispense the pills." Actually, we will be administering capsules, not pills.
