Background: Treatment switching in a randomized controlled trial is said to occur when a patient randomized to one treatment arm switches to another treatment arm during follow-up. This can occur at the point of disease progression, whereby patients in the control arm may be offered the experimental treatment. It is widely known that failure to account for treatment switching can seriously dilute the estimated effect of treatment on overall survival. In this paper, we aim to account for the… Expand

Assessing methods for dealing with treatment switching in clinical trials: A follow-up simulation study
TLDR
This work simulated randomised controlled trials incorporating prognosis-related treatment switching and investigated the impact of sample size, reduced switching proportions, disease severity, and alternative data-generating models on the performance of adjustment methods, assessed through a comparison of bias. Expand
Adjusting for treatment switching in randomised controlled trials – A simulation study and a simplified two-stage method
TLDR
This work assessed the performance of alternative adjustment methods based upon bias, coverage and mean squared error, related to the estimation of true restricted mean survival in the absence of switching in the control group and found that a simplified two-stage Weibull method produced low bias across all scenarios and provided the treatment switching mechanism is suitable, represents an appropriate adjustment method.

Adjusting for differential proportions of second-line treatment in cancer clinical trials. Part I: structural nested models and marginal structural models to test and estimate treatment arm effects.
TLDR
Two causal models, especially structural nested failure time models with randomized analyses, and marginal structural models are used to take the influence of second-line treatment into account and to test and estimate the direct treatment arm effect in cancer clinical trials. Expand
Assessing methods for dealing with treatment switching in randomised controlled trials: a simulation study
TLDR
A number of methods, particularly the AFT method of Branson and Whitehead were found to give less biased estimates of the true treatment effect in these situations and alternative approaches such as the Branson & Whitehead method to adjust for switching should be considered. Expand
Evaluating the effects of treatment switching with randomization as an instrumental variable in a randomized controlled trial
TLDR
This study utilized simulated data based on an ongoing randomized clinical trial (RCT) to evaluate the effects of treatment switching with randomization as an instrumental variable at differing levels of treatment crossovers, for continuous and binary outcomes. Expand
Gaining power and precision by using model–based weights in the analysis of late stage cancer trials with substantial treatment switching
TLDR
Simulations suggest that the weighted approach can lead to large efficiency gains in either an intention‐to‐treat or a causal rank‐preserving structural failure time model analysis compared with the unweighted approach. Expand
Correcting for noncompliance and dependent censoring in an AIDS Clinical Trial with inverse probability of censoring weighted (IPCW) log-rank tests.
TLDR
Evidence is presented that bactrim therapy improves survival but that the standard intent-to-treat comparison failed to detect this survival advantage because a large fraction of the subjects either crossed over to the other therapy or stopped therapy altogether. Expand
Adjusting for non-compliance and contamination in randomized clinical trials.
TLDR
In addition to providing a better estimate of the true effect of a treatment in compliers, the method provides a more realistic confidence interval, which can be especially important for trials aimed at showing the equivalence of two treatments. Expand
A new approach to causal inference in mortality studies with a sustained exposure period—application to control of the healthy worker survivor effect
TLDR
A graphical approach to the identification and computation of causal parameters in mortality studies with sustained exposure periods is offered and an adverse effect of arsenic exposure on all-cause and lung cancer mortality which standard methods fail to detect is found. Expand
Instrumental variables estimation of exposure effects on a time-to-event endpoint using structural cumulative survival models.
TLDR
A novel proposal under a class of structural cumulative survival models which parameterize time-varying effects of a point exposure directly on the scale of the survival function; these models are essentially equivalent with a semi-parametric variant of the instrumental variables additive hazards model.
