    [VIRTUAL] Preclinical Profile of SYD1875, a Novel Site- Specifically Conjugated Anti- 5T4 Antibody Drug Conjugate (ADC-USA 2021)
    Its preclinical profile supports the expectation that SYD1875 will be of benefit for a broad group of cancer patients. A first-in-human dose-finding trial is initiated to evaluate safety and explore efficacy (NCT04202705).

    ASN004, a 5T4-targeting scFv-Fc antibody-drug conjugate with high drug-to-antibody ratio, induces complete and durable tumor regressions in preclinical models. (PubMed, Mol Cancer Ther)
    In head-to-head studies, superior activity of ASN004 was demonstrated against trastuzumab-DM1, in a low-5T4/high-HER2 expressing gastric tumor model, and 10-fold greater potency was found for ASN004 against the 5T4-targeted ADC PF-06263507 in a lung tumor model. In marmoset monkeys, ASN004 was well tolerated at doses up to 1.5 mg/kg Q3W iv, and showed dose-dependent exposure, linear pharmacokinetics, and markedly low exposure of free payload drug. Taken together, these findings identify ASN004 as a promising new ADC therapeutic for clinical evaluation in a broad range of solid tumor types.
