Check my plan vs. these
Genotoxicity
Not conducted (ICH S6(R1))
“No genotoxicity studies were conducted as monoclonal antibodies do not directly interact with DNA or other chromosomal material, which is in line with ICH S6(R1) guideline.”
✓ VerifiedEMA assessment report, p. 48Source ↗
Carcinogenicity
Not conducted; weight-of-evidence carcinogenicity assessment
“No carcinogenicity studies were conducted. The applicant conducted a weight-of-evidence (WoE) assessment to evaluate the potential of depemokimab to cause carcinogenicity.”
✓ VerifiedEMA assessment report, p. 48Source ↗
Instead of carcinogenicity
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.

Reproductive & developmental
No DART studies conducted; risk assessed by weight-of-evidence
“No developmental and reproductive toxicity (DART) studies were conducted. The DART risk with depemokimab was assessed using a weight-of-evidence (WoE) approach.”
✓ VerifiedEMA assessment report, p. 48Source ↗
Safety pharmacology
No dedicated studies; CV endpoints in 26-week monkey study; ~7% QTc increase at 100 mg/kg (>70-fold clinical exposure)
“Cardiovascular parameters are specifically evaluated in toxicity study 2017N319933. In this study, an increase in QTc (approximately 7%) was observed in 4/6 animals at 100 mg/kg during Week 14 at an exposure that was >70-fold higher than clinical exposure.”
✓ VerifiedEMA assessment report, p. 45Source ↗
Genotox: Ames
Not conducted (ICH S6)

✓ VerifiedEMA assessment report, p. 48Source ↗
Genotox: in vitro mammalian
Not conducted (ICH S6)
“No genotoxicity studies were conducted as monoclonal antibodies do not directly interact with DNA or other chromosomal material, which is in line with ICH S6(R1) guideline.”

Carcinogenicity model
Not conducted; weight-of-evidence assessment
“No carcinogenicity studies were conducted. The applicant conducted a weight-of-evidence (WoE) assessment to evaluate the potential of depemokimab to cause carcinogenicity.”
✓ VerifiedEMA assessment report, p. 48Source ↗
Carcinogenicity timing
Not required: FDA judged a monkey carcinogenicity study unnecessary; mepolizumab data used
“After reviewing the nonclinical data, it was decided that conducting a carcinogenicity study in monkeys for depemokimab would not be necessary. Carcinogenicity information can be taken from the mepolizumab program.”

hERG / QT
No hERG assay; ~7% QTc increase in 4/6 monkeys at 100 mg/kg (>70-fold clinical exposure)
“In this study, an increase in QTc (approximately 7%) was observed in 4/6 animals at 100 mg/kg during Week 14 at an exposure that was >70-fold higher than clinical exposure.”
