Bringing Decades of Expertise in Clinical Study Design and Strategic Input for Your Successful Clinical Drug Development

Well-designed and well-executed clinical trials are critical to successful clinical development of drugs, biomarkers, and devices. You need a partner who will carefully help you plan the course of your clinical trial, proactively improve predictability, reduce risks, and help you reach Go/No-Go decisions faster. IDDI expert biostatisticians will partner with you to provide the optimal clinical study design, looking for efficacy signals to prioritize your pipeline and achieve better outcomes for the resources spent.

Our expert consultants have recognized expertise in clinical research, including biostatistics, clinical medicine, and regulatory science. This multi-disciplinary environment will greatly optimize your Clinical Development Strategy and better enable you to design and launch a successful clinical study. This includes developing the synopsis and the full protocol document, calculating the sample size for conventional, group-sequential or adaptive designs (including Bayesian designs), running trial simulations, and proposing innovative solutions to expedite and optimize chances of success of your clinical trial.

At IDDI, we have proven clinical trial design experience:

Flexible Approach to Clinical Study Design 
  • Our experts will tailor trial design according to the appropriate clinical phase and Clinical study designobjectives.

    • Phase I: Classical modified Fibonacci, continual reassessment method, other adaptive and model-based dose-escalation methods to improve efficiency
    • Phase II: Single-arm, randomized, adaptive, dose-finding, multi-stage, cross-over, biomarker-stratified, seamless phase II/III, basket and umbrella trials
    • Phase III: Superiority, non-inferiority, cross-over, group-sequential, adaptive, biomarker-stratified, factorial trials
    • Phase IV: Large, simple trials for “real-world” settings and comparative effectiveness research 
  • Strategic clinical drug development consulting services to help our clients face the challenges of clinical drug development: 
    • Input in the context of licensing deals and portfolio management
    • Guidance for IND and NDA submissions, biomarker approvals, paediatric exclusivity, and orphan drug designation, among others
