Participant Flow

Participants diagnosed with metastatic renal cell carcinoma (mRCC), aged above 18 years with at least one filled prescription of an oral targeted therapy relevant for treating mRCC, registered in the Swedish Prescribed Drug Register between 01-July-2005 and 31-Dec-2019, were included in this study and their data was observed retrospectively.

Participants were treated with sunitinib in the first line (1L) mRCC setting and with axitinib in the second line (2L) mRCC setting. The index date was the date of first identified prescription of the participant.

Population: Analysis population included all eligible participants whose data were retrieved from national registries and assessed.

TTD was defined as the difference between the start and end-dates for a treatment episode regardless of reason for discontinuation. The start date for a treatment episode was defined as the date of first dispensed package and the end date was defined as the date of the last dispensed package with the same Anatomical Therapeutic Chemical (ATC) code, plus the number of days that package, as well as accumulated medicine was intended to cover. End date was overruled if there was a new filled prescription of another relevant ATC code or death happens before this, then either of these dates represents the end date. If no end of prescribed supply was recorded, data was censored at latest available date in data.
