talquetamab · GPRC5D x CD3
Genotoxicity
Not conducted (ICH S6; biotechnology-derived product)
“Genotoxicity studies routinely conducted for pharmaceuticals have not been conducted and are not applicable to biotechnology-derived pharmaceuticals such as talquetamab per ICH S6.”
✓ VerifiedFDA multi-discipline review, p. 57Source ↗
Carcinogenicity
Not conducted (ICH S9; advanced cancer)
“As indicated in the ICH S9 guidance, carcinogenicity studies are not warranted to support marketing for therapeutics intended to treat patients with advanced cancer.”
✓ VerifiedFDA multi-discipline review, p. 57Source ↗
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
Not conducted (weight-of-evidence assessment; ADA limits exposure, no relevant species); reproductive organs examined in repeat-dose study
“We agree with the Applicant’s WOE-based approach for the assessment of reproductive and developmental toxicity.”
✓ VerifiedFDA multi-discipline review, p. 58Source ↗
Safety pharmacology
Incorporated into 1-month GLP monkey study with tool molecule (CV, respiratory, CNS); no effects
“However, cardiovascular, respiratory, and observational CNS safety pharmacology endpoints were incorporated into the 1-month GLP repeat dose toxicity study conducted with the tool molecule in cynomolgus monkeys”

Carcinogenicity model
Not conducted (ICH S9, advanced cancer)
“Carcinogenicity studies were not conducted with talquetamab. As indicated in the ICH S9 guidance, carcinogenicity studies are not warranted to support marketing for therapeutics intended to treat patients with advanced cancer.”

Carcinogenicity timing
Not required (FDA agrees not warranted)
“We agree that carcinogenicity studies are not warranted to support the approval of BLA 761342.”

hERG / QT
No hERG assay; tool molecule up to 30 mg/kg weekly had no effect on ECG, blood pressure, heart rate in monkeys
“The tool molecule (JNJ-64024701) at weekly IV doses up to 30 mg/kg had no effect on cardiovascular (electrocardiograms, blood pressure, heart rate), respiratory (respiration rate), or CNS (clinical observations and body temperature) parameters evaluated up to Week 4”
