Proveris by Design™ Study Descriptions




Patient Usage Ergonometric Studies

Provide critical, quantitative information on how patients in the product’s target age and gender group operate the product

  • Replicate human usage through automated actuation
  • Assess the Product(s) pump/valve delivery and priming specifications
  • For generics, ensure comparable usage to Reference Product
  • Comply with FDA Draft Guidance recommendations
  • Identify any patient usage issues

Reference Product Characterization

Determine the Product’s operating profile through a series of screening experiments to define the critical actuation parameters and develop methods for spray performance tests

  • Evaluate brand performance and manufacturing variability
  • Determine appropriate method(s) to achieve optimal in vitro bioequivalence (BE) correlation of spray performance

Device Component Optimization

Compare the Test Product’s formulation-device component combination(s) to the patient usage and spray performance of the Reference Product

  • Recommend an optimal Test device component combination(s) to achieve in vitro bioequivalence (BE) correlation of spray performance
  • Evaluate and assess variables in formulation-device component combinations

Method Development

Utilize a Patient Usage Study to screen the critical actuation parameters and develop spray pattern and plume geometry methods on the SprayVIEW® Measurement System

  • Deliver robust, reliable methods for accelerated Product development and verification
  • For generics, confirmation of device selection and overall performance

Method Transfer and Verification

Ensures rapid implementation and use of method(s) on new or existing systems

  • Facilitate site to site transfers, new installations, new method deployment on existing systems, and outsourcing to contract service organizations
