ZW191 is the Company's novel folate receptor-⍺ (FR⍺) targeted topoisomerase I inhibitor (TOPO1i) antibody-drug conjugate (ADC).
The Company expects to file applications seeking regulatory authorization to initiate clinical studies for ZW191 in non-US jurisdictions in the second half of 2024.
ZW191 is the first of three ADC molecules incorporating the Company's proprietary ZD06519 payload designated for clinical development, with IND filings for ZW220 (NaPi2b ADC) and ZW251 (GPC3 ADC) on schedule for 2025.
