New Methods for Two‐Stage Treatment Switching Estimation

Pharmaceutical Statistics
ABSTRACTTreatment switching is common in randomized trials of oncology treatments. For example, control group patients may receive the experimental treatment as a subsequent therapy. One possible estimand is the effect of trial treatment if this type of switching had instead not occurred.
