Rozibafusp alfa is under clinical development by Amgen and currently in the Phase II in clinical pathway. The characteristics of the clinical trial as well as other attributes related to the drug, regulations, and company play a fundamental role in ensuring the likelihood of transition that the drug moves from its current development stage to next.

According to GlobalData, the latest event to affect Rozibafusp alfa’s likelihood of approval (LoA) and phase transition for Systemic Lupus Erythematosus took place on 27 Jan 2021, which decreased the likelihood that the drug progresses to the next phase in its clinical pathway and decreased the likelihood of final approval for this indication.

GlobalData uses proprietary data and analytics to provide a complete picture of this assessment in their Rozibafusp alfa Likelihood of Approval (LoA) and Phase Transition Success Rate (PTSR) Report.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
