From the article:
"The ReAnima Project has just received approach from an Institutional Review Board at the National Institutes of Health in the US and in India, and the team plans to start recruiting patients immediately."
I'm not British, so maybe it's isn't a mistake but I think the word "approach" should have been "approval".
Basically, they got IRB approval for the study. They mention NIH, because the NIH's Office of Science Policy has rules and criteria for the formation of hospital's or university's IRB. I don't know the details of the study, but my guess is that local hospital where the trial is to take place gave approval. They mention NIH because it gives it an air legitimacy. I'm not saying this isn't a legit study, but I think all the NIH did was to approve the formation and composition of the IRB, not the actual study.
