No, cell therapy companies but even other new tech companies often take a long time to file their applications after announcing their results. Manufacturing is an important part of that application and is given a lot of importance in the application process. They want a consistently replicable drug.
The fact that this is fairly transparent seems to literally lead to people complaining they don’t know enough, and it’s “delayed”. It’s in process and moving along. Some companies announce their results and rush the applications only to be rejected because of manufacturing issues (usually inconsistency or unreliable product) and then taking a few years again before they reapply, based on the same trial data, to get approval.
