XG-005 is under clinical development by Xgene Pharmaceutical and currently in Phase II for Post-Operative Pain. According to GlobalData, Phase II drugs for Post-Operative Pain have a 53% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how XG-005’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

XG-005 overview

XG-005 is under development for the treatment of acute and chronic pain including post operative pain, low back pain, traumatic pain, painful knee osteoarthritis. The drug candidate is a conjugate of naproxen and pregabalin. It is administered through oral route as a tablet and capsule.

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.
