If the treatment is showing good efficacy it should be a cinch to enroll such small numbers. So it begs the question, why would they sabotage their own company?
Were you able to ask about data subsets. My line of conjecture would be they saw a commonality in patients with good outcomes, approached the FDA to narrow the indication and had to increase sample size. Only positive reason why it's taking forever. Yes that will really change the future of this company. Just trying to keep a positive spin. Were you able to get them to talk data at all or tell you it is going to be the greatest thing since sliced bread.
"Originally the trial was supposed to enroll 37 patients. No reason it should not be fully enrolled by now at 37 patients. The next data release better be at least 30 patients. There is no excuse for anything less than that." I HOPE THAT YOU ARE CORRECT. Any excuse after this much time to enroll will just be BS.
