19. Serious medical or psychiatric conditions that might limit the ability of the participant to comply with the protocol.
20. Pregnancy, lactation, or inadequate contraception. Women must be post-menopausal, infertile, or use a reliable means of contraception.

Safety/efficacy
Statistical methods / analysis
Using Simon 2-stage design, 49 evaluable patients will provide
80% power to exclude a clinically uninteresting OTRR of 29% or
less in favour of a clinically interesting rate of 46% or greater,
with a one-sided alpha of 5%. If there are 8 or fewer responses
in the first 28 patients, consideration will be given to stopping the
study for futility. The null hypothesis will be rejected if 20 or more
objective tumour responses are observed in 49 evaluable
patients. A total of 52 patients will be recruited to account allow
for patient dropout.
The uninteresting OTRR of 29% or less is based on the lower
bound of the 95% CI reported for sotorasib monotherapy. OTRR
of 46% or greater is of clinical interest, as it exceeds the
performance of either sotorasib monotherapy or the combination
of carboplatin/pemetrexed/bevacizumab.
