Acetaminophen is under clinical development by Angelini 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 Acetaminophen’s likelihood of approval (LoA) and phase transition for Patent Ductus Arteriosus took place on 17 Nov 2021, which increased the likelihood that the drug progresses to the next phase in its clinical pathway.

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

Acetaminophen overview

Paracetamol (Tachipirina / Tachiverde) is a derivative of acetanilide, acts as analgesic and antipyretic drug. It is formulated as tablet, syrup, granules, effervescent tablets for oral route of administration, injection, solution for intravenous and suppository for rectal route of administration.

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.
