FIH Failure Rate Claims Validated Against Database
Verified IP memo claims on FIH trial failure rates using database query against trial table joined with trial_mechanism. ADC FIH trials demonstrate operational maturity with only 3.7% failure rate (4/107 trials withdrawn or terminated), while bispecific FIH trials show 7.9% failure rate (10/127), confirming bispecific modality carries higher execution risk. The 2.14x failure rate differential supports memo’s strategic recommendation to build separate FIH playbooks for ADCs versus bispecifics with different site selection and risk management criteria. Query methodology provides reproducible validation approach for future data updates.
Concepts: [“how-it-works”,“what-changed”]
Facts: [“ADC FIH trials show 4 failures out of 107 total trials yielding 3.7% failure rate”,“Bispecific FIH trials show 10 failures out of 127 total trials yielding 7.9% failure rate”,“Failure defined as overall_status IN (‘WITHDRAWN’, ‘TERMINATED’)”,“Bispecific FIH failure rate is 2.14x higher than ADC FIH failure rate”]
