Before receiving FDA approval, the tTAV protein had to be tested for any potential toxicities to other native animals. Why would this be part of the approval process?
Given what we know, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.
Why is this testing important?FDA toxicity testing for potential toxicities native to other animal species can be an essential part of any approval process. This part of the process ensures that the compound in question is free of toxins that not have been noticed in previous tests due to the innate resistance of the animal it was tested on, to begin with. This allows for a more thorough screening process and a safer end product.
Therefore, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.
