Integrated Summary Writing Services

Comprehensive ISS and ISE documents that synthesize your clinical program

Integrated summaries bring together data from across your clinical development program to present a comprehensive picture of your product's efficacy and safety. These documents are essential components of NDA and BLA submissions, providing FDA reviewers with the pooled analyses and cross-study comparisons they need to evaluate your product.

Documents We Develop

Integrated Summary of Safety (ISS)

The ISS presents pooled safety data across your clinical program including extent of exposure, adverse events, serious adverse events, laboratory abnormalities, and special populations analyses.

Integrated Summary of Efficacy (ISE)

The ISE presents pooled efficacy data supporting your proposed indication including primary and secondary endpoints, subgroup analyses, dose-response, and persistence of effect.

ISS Content Coverage

  • Extent of exposure across studies and populations
  • Adverse events by system organ class and preferred term
  • Serious adverse events and deaths
  • Adverse events leading to discontinuation
  • Laboratory abnormalities and vital signs
  • Special populations and subgroup analyses
  • Drug interactions and overdose

ISE Content Coverage

  • Study design and patient population overview
  • Primary and secondary endpoint analyses
  • Subgroup analyses and consistency of effect
  • Dose-response relationships
  • Persistence of effect and durability
  • Comparison with active controls (when applicable)

Our ISS/ISE Development Process

1. Analysis Planning

We work with your biostatistics team to review the integrated analysis plan and understand pooling strategies.

2. Shell Development

We create detailed document shells aligned with FDA expectations and your submission strategy.

3. Data Integration

We incorporate pooled analyses, cross-study comparisons, and subgroup analyses into clear narratives.

4. Cross-document Alignment

We ensure consistency between ISS, ISE, Module 2.7 summaries, and individual CSRs.

Frequently Asked Questions

When should we start ISS/ISE development?

Integrated summary development typically begins 6-9 months before NDA submission, after pivotal study topline results are available. Planning can start earlier to align pooling strategies.

How do you coordinate with biostatistics?

We work closely with your biostatistics team throughout development. We participate in analysis plan discussions, review draft outputs, and iterate on presentation approaches.

Can you support ISS/ISE updates for supplemental applications?

Yes. We can update existing integrated summaries to incorporate new studies or extended follow-up data for supplemental NDAs, new indication applications, or post-marketing commitments.
