Published: July 20th, 2026

Designing a first-in-human study is challenging. Designing one for a novel reproductive therapy with limited prior data and significant biological variability is even more complex. 

In this case study, discover how Phastar partnered with an innovative biotechnology company developing a groundbreaking therapeutic aimed at improving IVF success rates through the reduction of chromosomal errors in oocytes. 

Using advanced simulation methodologies and close scientific collaboration, Phastar helped transform uncertainty into a robust, statistically validated study design capable of delivering meaningful proof-of-concept evidence. 

Download the case study to learn how: 

  • Simulation-based approaches informed sample size determination 
  • Multiple biological and treatment-effect scenarios were evaluated 
  • Critical assumptions were refined through scientific collaboration 
  • Key uncertainties were systematically explored and mitigated 
  • Primary endpoints were optimized to strengthen evidentiary value 
  • Statistical outputs were aligned with future development decisions
