If the FDA in only doing written responses there i

If the FDA in only doing written responses there is no point in asking for an in person or teleconference response.

That was just the FDA's boilerplate letter noting that GNBT requested it be a written response and that it is granted. If they had requested in person or teleconference, they would have been either rejected, or told that only written in possible currently.

But please, continue bashing the management team because you would have liked an in person or teleconference response. Everyone would like that, but that is not an option.
