Great question, Kumar. So I call that amendment approval, I call it the $20 million amendment here at BioCardia because of how significantly it’s going to change, how easy it is to enroll patients in the trial. Previously, if a patient didn’t meet the pre-specified cell population analysis criteria, they were excluded from the trial. Now, we took measures throughout the trial, and in our analysis of the CardiAMP Heart Failure cell population analysis data for both the patients who didn’t make it into the trial and the patients who did make it into the trial, we saw that there was a large portion of the patients that were just really under the threshold, within, say, 35% of the threshold. And so we went to the agency and we presented a plan whereby for those patients, to help ensure that they have potential to reach the target dosage, instead of excluding them, we are going to give them 35% more deliveries. So currently, we treat patients with 10 dosages around damage and infarct sites. For those patients that are in a class that doesn’t meet the full cell population analysis score, those that fall below but are greater than 65% will then be targeted with the 10 dosages, plus an additional five dosages to get them to the optimal target dosing. And so we’re pretty excited about this. It has -- we’re not detailing the exact numbers and all the details and changes yet because, again, we don’t yet have final data in the trial. But our expectation is that, we will still exclude patients based on not having appropriate cells for therapy. But my expectation, and I should say our expectation of the team, is that about 85% of the patients will pass that threshold and a number of them will wind up having 15 deliveries to get to the target dosage versus the 10. So this is truly personalized medicine, where we’re assessing a patient’s own autologous tissue, looking at it for its composition and then developing a treatment plan, which now has three arms. One arm is, I’m sorry, your cells don’t qualify you for treatment. The other arm is, yes, your cells qualify you for treatment. And the third arm is, your cells qualify you for treatment, but because of the nature of your cells, we’re going to provide an additional five dosages. So that’s what we’re rolling out now and all the paperwork’s been implemented here at BioCardia. We have IRB approval. The full CardiAMP Heart Failure trial, Heart Failure II trial, will incorporate that element.
