Comments about company or candidate Dec 2019: Accelerated approval granted by FDA. July 16, 2019: A Biologics License Application (BLA) for enfortumab vedotin has been submitted to the FDA for a potential accelerated approval as a treatment for patients with locally advanced or metastatic urothelial cancer who have previously received a PD-1/PD-L1 inhibitor and platinum-containing chemotherapy in the neoadjuvant/adjuvant, locally advanced, or metastatic setting. NCT03474107 Phase 3 study in Urothelial cancer started in June 2018. March 2018: The FDA awarded breakthrough designation to an antibody-drug conjugate as a second-line treatment for locally advanced or metastatic urothelial cancer. Oct. 10, 2017-- Seattle Genetics, Inc. and Astellas Pharma Inc. announced dosing of the first patient in EV-201, a registrational phase 2 clinical trial of enfortumab vedotin for patients with locally advanced or metastatic urothelial cancer who have been previously treated with checkpoint inhibitor (CPI) therapy. The EV-201 study will assess the antitumor activity and safety of enfortumab vedotin to support potential registration under the U.S. Food and Drug Administration’s (FDA) accelerated approval regulations. Listed as Phase 2 in Astellas pipeline dated Jan 2017; NCT03219333 Phase 2 study recruiting as of July 20 2017. NCT02091999 Phase 1 recruiting as of Jan 2017. Listed as Phase 1 in pipeline dated Feb 2013. AGS-22M6E and ASG-22CE are fully human monoclonal antibody conjugated to a cytotoxic agent monomethyl auristatin E (MMAE) targeting Nectin-4 (Agensys code name AGS-22). The main difference between AGS-22M6E and ASG-22CE is the change in cell line for antibody production.

Description/comment

DAR: ave 3-4; mc-val-cit PABC linker. The enfortumab vedotin active substance (AS) consists of fully human IgG1 mAb intermediate, AGS22C3, conjugated to the drug-linker (DL) intermediate of SGD-1006 (microtubule-disrupting agentMonomethyl auristatin E (MMAE)) via thioether bonds, forming an ADC. The ADC has an average molar drug to antibody ratio (DAR) of approximately four drug molecules per antibody, resulting in a heterogeneous mixture of active conjugated isoforms.
