As I have already mentioned dig deeper!
What this NYS CLeP process requires is that the lab submit documentation to demonstrate that their laboratory procedures and admin are to a required standard. It is validation of those. It does not mean that thousands of tests have suddenly been done on patients at a scale and diversity to satisfy the medical community. Besides CiRT would also require months of follow-up to demonstrate that the tests have accurately predicted immunotherapy outcomes.
NYS CLeP accept the evidence submitted that the test appeared to.work on the very small cohort tested (a couple of hundred if memory serves) but doctors will want evidence from thousands of patients of different ages, ethnic backgrounds etc before the test is deemed clinically validated.
'Laboratory validated' is a much abused term in this industry and that is why this 'final ruling' has been made by FDA. Their next move will be to require full scale clinical trials of future LDT's. This is just an interim step towards that.
