Hi, my mum developed resistance to Afatinib after around 7 months. Docs did a rebiopsy and found T790 mutation so they're switching her to Tagrisso 80mg. Would like to verify that the gap days from her last intake of Afatinib has to be at least 10 days before starting Tagrisso? I only found one material online regarding this which states that the median time between stopping Afatinib and starting Tagrisso is between 10-16 days. Many thanks!
