Case Study: IB Excellence
How EloquiMed streamlined IB development for a complex biologics program
Challenge
A biotech company developing a novel antibody-drug conjugate (ADC) needed a comprehensive IB for their first-in-human study. The molecule had a complex mechanism of action and preliminary toxicity findings requiring careful communication.
Solution
Scientific Expertise
Assigned writers with specific ADC and oncology experience who could interpret complex preclinical data.
Visual Communication
Developed custom illustrations explaining the unique mechanism of action and target engagement.
Risk Management Focus
Created detailed guidance for managing novel toxicities based on limited preclinical data.
Regulatory Strategy
Incorporated regulatory feedback from pre-IND meeting to address specific concerns proactively.
