The second announcement I circled a paragraph. The first is the request for more data from the FDA. No mention that they need new data. what is it about this sentence that you don't understand? I've underlined the word requires because it seems you thinks needs and requires are different? "...(FDA) has provided a complete response to its Biological License Application (BLA) resubmission for remestemcel-L ...... and requires more data to support marketing approval"The reason that I tagged you is that from what I understand is that you believe that the only possible way to provide data is to create new data from the then proposed trial in adults. Oooookay.. That is near enough.The FDA do not agree with you. They have apparently been dumped down according to your standards. Ooookay. But you are jumping ahead to much more recently (like to 27 March 2024 and MSBs announcement) and believing entirely that what MSB has announced to be accurate and not some misunderstanding, when you say the FDA do not agree with me, now , aren't you? And yes, for the general message as presented in the 27th of March 2024 and for the words conveyed by Silviu (perhaps he was misquoted) to be a true representation of the FDA's actual position I do think the FDA would have to be much dumber much less capable than they were of sorting through the data and drawing sound conclusions than they were - yes that is my position - but I think its more likely that the error(s) are coming from MSB misreporting or misunderstanding what the FDA has said than that the FDA has dropped their standards. The second announcement I circled a paragraph. You did - this one. "FDA noted that the lack of of a suitable potency assay for the RYONCIL product used during the Phase 3 trial MSB-GVHD001 for the pediatric acute GVHD indication has prevented the trial from being considered an adequate study for the purpose of demonstrating substantial evidence of effectiveness required for a marketing approval. " At the time MSB announced this (21 september 2023) it seems the FDA did EXACTLY agree with me. Although then as now I'm only getting what the FDA thinks second hand from MSB as are you. BUT BE CLEAR - that alone will not be enough - they must have a suitable potency assay AND THEN use it in new patients to verify it and to get new uncontaminated readings from blood - they cannot use dodgy confounded data from a time when they didn't have a good enough potency assay as it will not be clear that the good longevity results they got from a batch or batchesy used then where not due to something else in the product batch or batches used that may not be in the new batches. And if there is some magical mystery batch - they can't keep using it - they'll run out of it. The final decision of the FDA to CRL 2 . Yes. Not important apparently ,catch up. Yes it was important. As for catch up - I reply make some bloody sense then and be clearer because its is not at all evident that you are going anywhere when you suggest you are ahead of me when its not clear from how you write that you aren't lost yourself. SI then goes on and quoted the regulation . Thus -"Mesoblast intends to generate in the coming months new potency assay data for RYONCIL showing that the product used during the pediatric Phase 3 trial MSB-GVHD001 was standardized as to its identity, strength, quality, purity and dosage form to give significance to the results of the investigation as described in the Code of Federal Regulations for adequate and well controlled studies (21 CFR 314.126), and that the commercial batches made for the pediatric indication will meet the same standard" I think that regulation reference (21 CFR 314.126) is useful. For new readers for "adequate and well controlled trial". So that was the intent at 20 September 2023. But then, again, I refer you to Silvius own words at the Hidden Gems webinar of 7 March 2024 (linked in a recent post of mine) "we've just reanalysed the data in a, I would say more robust way, and we've provided all the data to the FDA, and we think it more than meets, their criteria". That isn't new blood from new patients - not even new blood from new EAP patients. As you think that you are all over our patents I wouldn't say I'm all over your patents - I would say I've read a relevant patent that was granted (21 november 2023 (don't think MSB announced that though at the time)) and a patent application that wasn't granted as of a couple of days ago and I haven't checked since. Those are the patent and patent application in which MSB describe the potency assay components TNFR1 and ILR2alpha levels. could I suggest that you re-examine that chart with the 11 points on it. You have missed the bleating obvious . Hint it is not what you can see, its what you cannot. Why don't you excerpt it for me - I am fascinated as to how you are going to have me (or any other readers) see the bleating obvious - that can't be seen.

Requiring NEW is just your assumption. There is no reason they cannot apply the better assay data to the old trial data already supplied which the FDA can now consider. The cells are already viable for something like 4 years minimum in storage so your NEW argument is just wrong.
