HEOR analysis of the RCT data
1

We analyze both RCT data and real-world observational data, including surveys, claims databases and registries.

​

Our goal is to fully exploit their HEOR potential, and explore additional treatment effects.

​

We analyze Phase 2 and Phase 3 FDA-approved STDN ADAM datasets in SAS.

What for?

Efficient use of existing resources, resulting in deep insight in own clinical data (40-80 new data tables).

Allows for data exploration and finding of additional treatment effects

HEOR analysis of RCT data
Psychometric performance of PRO or clinical endpoints
2

What for?

  • To better understand the items and the total score of a PRO

  • To identify the most responsive items

  • To explore treatment effects on items

  • To validate the PRO in the study population

Psychometric performance PRO of clinical endpoints
Determining the MCID of a PRO or clinical endpoint
3

What for?

  • To calculate the minimum amount of change in a (primary or secondary endpoint) PRO that represents a true change in the patient’s health condition.

  • Results are used to interpret study results, recalculate treatment effect on a secondary endpoint, and calculate the proportion of responders.

Determining the minimal important difference of EQ-5D-5L utility values in CIDP patients using data from a large clinical trial. To be submitted


Estimating the Minimal Clinically Important Difference for the Myasthenia Gravis Quality of Life revised scale (MG-QOL15r). Submitted Qual Life Res

MCID of a PRO or clinical endpoint
Mixed methods and textual analysis
4

What for?

We analyze qualitative data in NVIVO, to understand what patients find important:

  • Which symptoms are most or least burdensome?

  • Are there symptoms not included in the clinical study programme?

  • Which symptoms would they choose to alleviate first?

  • What are the most experienced symptoms?

It is important to integrate the patient's voice in the selection of endpoints.

Mixed methods & textual analysis
Other statistical analysis techniques

We use SAS/STATA, R, Python or VBA, and a variety of analysis techniques including, but not limited to:​​

  • Survival analysis

  • Longitudinal analysis, with missing data methods

  • Resource utilization and cost analysis

  • Time-series analysis

  • Multilevel analysis

  • Analysis of discrete choice experiments

  • Factor analysis

  • Clustering analysis

  • Propensity score adjustment for non-randomization
