Antibody-drug conjugates (ADCs) are promising biotherapeutics composed of an antibody plus a cytotoxic payload via a chemical linker, thus allowing the delivery of cytotoxic payload to target cancer cells. Among cancer glycoproteins studied in cancer research, mucin-1 (MUC1) is among the most extensively researched.
Remegen Ltd. has synthesized antibody-drug conjugates consisting of anti-CDCP1 antibodies covalently linked to cytotoxic drugs through linkers reported to be useful for the treatment of cancer.
Arbele Pte Ltd.’s ARB-1002 has been awarded orphan drug designation by the FDA for the treatment of pancreatic cancer. ARB-1002 is an antibody-drug conjugate comprising an anti-CDH17 monoclonal antibody chemically linked to a potent cytotoxic agent.
Elasmogen Ltd. has identified antibody-drug conjugates comprising antibodies covalently linked to a cytotoxic drug through a linker reported to be useful for the treatment of cancer, autoimmune and inflammatory disorders.
Haisco Pharmaceutical Group Co. Ltd. has disclosed antibody-drug conjugates consisting of antibodies covalently linked to antitumor drugs through a linker reported to be useful for the treatment of cancer.
Crescent Biopharma Inc. has announced regulatory clearances of IND applications for CR-001 (SKB-118), a PD-1 x VEGF bispecific antibody, and CR-003 (SKB-105), an integrin β-6 (ITGB6)-targeted antibody drug-conjugate (ADC), both being developed for the treatment of advanced solid tumors.
Jiangsu Simcere Pharmaceutical Co. Ltd. has identified antibody-drug conjugates (ADCs) comprising antibody or antigen-binding fragments linked to a cytotoxic drug through a linker reported to be useful for the treatment of atopic dermatitis.
Innolake Biopharm (Hangzhou) Co. Ltd. has disclosed antibody-drug conjugates comprising bispecific antibodies covalently bound to exatecan through a linker reported to be useful for the treatment of cancer.
Over the course of the year, and continuing into the latest scientific meetings, an extraordinary breadth of new antibody-drug conjugate (ADC) designs was reported, with innovations spanning targets, linkers, payloads, conjugation chemistries and overall architectures. Once defined by a simple “one target, one payload” model, the field is lately expanding into a more versatile and diverse therapeutic space.
