Late Phase

You have successfully completed several early phase studies. Now XP Pharma Consulting works with you utilizing quantitative tools and strategies that facilitate successful data interpretation and reporting. We help you design pivotal studies that will generate the PK/PD data required to secure a successful clinical pharmacology package for NDA/BLA filing. We employ innovative modeling and simulation techniques to justify the doses in the labeling, avoid certain late-phase studies, build a bridge strategy to pediatric
populations, simulate clinical studies under different scenarios, and more:

Clinical Pharmacology Strategy & Writing

  • Gap analyses/Question Based Review (QBR)
  • Study protocol (in full or in part) and review
  • Study report (in full or in part) and review
  • Assess need for DDI studies
  • Determine TQT waivers and prepare application packages
  • Assess a need for a thorough QT (TQT) study
  • Author TQT study waiver (in full or in part)
  • Pediatric dose determination for PIP and PSP
  • Regulation documents preparation (PK/PD)
  • Regulatory meeting representations
  • Conduct comparator PK/PD data analyses

Noncompartmental PK/PD/TK

  • Noncompartmental analysis

Clinical Pharmacology Studies

Clinical pharmacology studies are necessary for understanding the PK and PD properties of your drug. XP Pharma Consulting works with you to evaluate regulatory feedback and available data to identify the necessary studies. XP Pharma Consulting can assist in generating the study design, synopsis, and protocol for trials of following types:

  • First-in-human (FIH)
  • Single ascending dose (SAD)
  • Multiple ascending doses (MAD)
  • Bioequivalence
  • Relative bioavailability
  • Food effects
  • Drug-drug interactions (DDI)
  • Thorough QT (TQT)
  • Pediatric PK/PD bridging to adult dose study
  • PK in hepatic-impaired subjects
  • PK in renal-impaired subjects
  • Radio-labeled mass balance (ADME and metabolic profiling)
