Richard Besserman MD sent a message to Andrew Witty that said:
I wrote to the NUCALA division manager in April with no response. Have an issue and need assistance. I can provide a copy of what I sent to am private email. I'm the patient this time around. Not familiar with the issues that your people have with Mayo prescribers but that should not make a difference. Cant blame this on on Covid-19.
Maybe you can open the channel - the call centers are useless.
