First doseopen answer page →
The public FDA and EMA reviews of Opdivo don't say how the first human dose was chosen. That rationale is in the IND, which is confidential, so it is missing for most approved products.
ADCs with cytotoxic payloads follow the S9 rules (1/10 STD10 or 1/6 HNSTD of the ADC, scaled by body surface area). For immune agonists, a MABEL-based start dose should be considered instead.
NOAEL / key findings: Well tolerated up to 50 mg/kg in 4- and 13-week monkey studies (FDA pharmacology/toxicology review, p. 13)
