FDA recommends the labeling describe any factors that may affect flow accuracy such as ambient temperature, fluid temperature, pressure (e.g., head height, backpressure, atmospheric pressure), fluid viscosity, or changes in flow rate or bolus delivery (e.g., such as when titrating medications).
CRL_NDA216962_20230317:p1:s21Please note, some of the recommended factors may be included in the labeling and/or are inapplicable; however, the labeling for Vyafuser does not include information regarding head height or backpressure.
CRL_NDA216962_20230317:p1:s22EPRs are essential design inputs and outputs critical to achieving the intended use of the device which, in this case, is successful delivery of the drug product as identified by AbbVie.
CRL_NDA216962_20230317:p1:s35The comments in this section are not intended to convey human factors (HF) approvability issues with your proposed product; however, it will be necessary for you to consider how any revisions to your proposed product to address the deficiencies outlined above will impact your user interface.
CRL_NDA216962_20230317:p8:s11If your user interface is revised in response to the CR, you should update your use-related risk analysis (URRA) to determine whether any new risks, including new critical tasks or failure modes are introduced by the changes.
CRL_NDA216962_20230317:p8:s12We strongly recommend you submit this information to the Agency for review prior to resubmitting NDA 216962 to ensure the Agency agrees with your determination regarding the HF data need to support your revised user interface.
CRL_NDA216962_20230317:p8:s15If you determine that you do need to submit the results of an additional HF validation study for your revised user interface, we recommend you submit your study protocol for feedback from the Agency before commencing your study and prior to resubmitting NDA 216962. Note that submission of a protocol for review is not a requirement.
