Therapeutic Applications and Target Strategies of Antibody-Drug Conjugates in Ovarian Cancer.
(PubMed, Iran J Pharm Res)
- "This review summarizes a range of ADCs targeting tumor-associated antigens in ovarian cancer, including mirvetuximab soravtansine (MIRV), trastuzumab deruxtecan (T-DXd), datopotamab deruxtecan (Dato-DXd), sacituzumab tirumotecan (SKB-264), PF-06664178, anetumab ravtansine (BAY 94-9343), BMS-986148, DMOT4039A, RC88, lifastuzumab vedotin (DNIB0600A), upifitamab rilsodotin (ABBV-181), ZW220, DMUC4064A, and sofituzumab vedotin (DMUC5754A). The ADCs hold significant potential to reshape the treatment landscape for ovarian cancer by providing targeted therapeutic options. Further research is required to optimize patient selection, address resistance mechanisms, and improve safety profiles."

Zymeworks Provides Corporate Update and Reports Second Quarter 2025 Financial Results
(GlobeNewswire)
- "R&D expenses were $34.4 million in 2Q-2025 compared to $29.2 million in 2Q-2024, primarily due to an increase in expenses for ZW171, ZW191 and other preclinical expenses related to IND-enabling studies for ZW209 and ZW251. These were partially offset by a decrease in expenses for zanidatamab zovodotin and ZW220."

Zymeworks Provides Corporate Update and Reports Fourth Quarter and Full Year 2024 Financial Results
(GlobeNewswire)
- "Based on our encouraging preclinical results and the unique potential opportunity to help hepatocellular carcinoma patients, we have decided to reprioritize resources for the advancement of ZW251, for which an IND submission is now planned for mid-2025. As a result, we have paused preparations for the commencement of Phase 1 studies of ZW220 at this time. However, we believe ZW220 remains a highly differentiated, IND-ready ADC with encouraging preclinical data and strong commercial rationale with partnership potential. We look forward to providing future updates on the development for ZW220....'We look forward to initiating a Phase 1 trial for ZW251 this year'."

Zymeworks Presents New Preclinical Data on Antibody-Drug Conjugate Programs at EORTC-NCI-AACR Conference
(GlobeNewswire)
- "Results demonstrate that ZW220 has the potential for improvement over previous NaPi2b ADCs and on the basis of efficacy, tolerability and payload mechanism.... We believe it offers a differentiated safety profile compared to other ADCs currently in the clinic, demonstrating high tolerability in animal studies with MTD ≥90 mg/kg in non-human primates (NHP) and ≥200 mg/kg in rats, suggesting potential for high doses in humans. The low drug-antibody ratio (DAR) and moderate stability of the antibody-linker provide a good balance of stability, tolerability, and anti-tumor activity, while potentially minimizing antibody-driven toxicities....Presentations highlight key preclinical data that support investigational new drug application (IND) submissions for ZW220 in 1H and ZW251 in 2H in 2025."

ZW220, a NaPi2b-directed topoisomerase I inhibitor Antibody-Drug Conjugate, demonstrates compelling preclinical activity in NSCLC, ovarian and uterine cancer models, with a favorable toxicology profile in non-human primates
(EORTC-NCI-AACR 2024)
- "Taken together, the results support the therapeutic potential of ZW220 as a novel ADC which may help address unmet medical need in patients with NaPi2b-expressing tumors. An IND application is anticipated in 2025."

ZW220, a novel NaPi2b-targeting antibody drug conjugate bearing a topoisomerase 1 inhibitor payload
(AACR 2023)
- "ZW220 antibody exhibited cross-reactivity to human and cynomolgus monkey NaPi2b, nanomolar binding affinity and rapid internalization in NaPi2b-expressing cell lines in vitro. ZW220 elicited target-specific, sub-nanomolar cytotoxicity in two-dimensional monolayer and three-dimensional tumor spheroid models and demonstrated bystander-mediated cell killing in cancer cell co-culture assays. The treatment of a panel of ovarian PDXs with a single dose of 6 mg/kg of ZW220 resulted in robust tumor growth inhibition."
