New without box: A brand-new, unused, and unworn item (including handmade items) that is not in original packaging or
may be missing original packaging materials (such as the original box or bag). The original tags may not be attached. For example, new shoes (with absolutely no signs of wear) that are no longer in their original box fall into this category.

sars-cov-2 remdesivir resistance mutations have been generated in vitro but have not been reported in patients receiving treatment with the antiviral agent. we present a case of an immunocompromised patient with acquired b-cell deficiency who developed an indolent, protracted course of sars-cov-2 infection. remdesivir therapy alleviated symptoms and produced a transient virologic response, but her course was complicated by recrudescence of high-grade viral shedding. whole genome sequencing identified a mutation, e802d, in the nsp12 rna-dependent rna polymerase which was not present in pre-treatment specimens. in vitro experiments demonstrated that the mutation conferred a ~6-fold increase in remdesivir ic50 but resulted in a fitness cost in the absence of remdesivir. sustained clinical and virologic response was achieved after treatment with casirivimab-imdevimab. although the fitness cost observed in vitro may limit the risk posed by e802d,
