Zymeworks, a clinical-stage biopharmaceutical company developing multifunctional biotherapeutics including bispecific antibodies and bispecific antibody-drug conjugates across a wide range of therapeutic indications, has won the 6th Annual World ADC Awards in the Best ADC Platform Technology Category for ZymeLink,™ a propitiatory ADC platform technology.
The awards ceremony took place on Thursday October 10, 2019 at the Manchester Grand Hyatt, San Diego, California during 10th annual World ADC 2019, a ‘must attend’ industry meeting for anyone involved in the development and manufacturing of ADCs, held October 8 – 11, 2019 in San Diego, CA.
Novel antibody-drug conjugate
ZW49, Zymeworks’ investigational antibody-drug conjugate, was created using the company’s proprietary Azymetric™ and ZymeLink™ technology platforms. The trial drug is an anti-HER2 biparatopic antibody designed to targets two distinct HER2 epitopes and binds to the same domains as trastuzumab and pertuzumab, conjugated to a cleavable linker and novel auristatin payload. 
The agent is currently in a first-in-human, Phase I, multicenter, open-label, dose-escalation study (NCT03821233) to establish the maximum- tolerated dose (MTD) or recommended dosage (RD) to assess the safety and tolerability. The trial includes patients with locally advanced, unresectable or metastatic high and low HER2-expressing cancers and addresses unmet medical needs, including brain metastases.
Interim trial data, reported during the 2018 San Antonio Breast Cancer Symposium (SABCS) held in December 4-8, 2018 in San Antonio, Texas, demonstrated that ZW49 was well-tolerated in preclinical studies, with efficacy competitive to ado trastuzumab emtansine (T-DM1; Kadcyla®, Genentech/Roche). The available toxicology data confirmed the safety of dosing above predicted efficacious level.
Zymeworks’ Azymetric™ platform includes a suite of proprietary, transferable, amino acid changes in the monoclonal antibody CH3 domain to facilitate interaction of two distinct heavy chains that can be introduced to generate bispecific IgG-like antibodies that bind two antigens.
These amino acid changes are also introduced at the heavy-light chain interfaces where they facilitate the correct pairing of the heavy chains with their respective cognate light chains.
The resulting Azymetric™ antibodies are compatible with glyco-engineering and other Fc modifications to enhance therapeutic activity.
The technology was developed to specifically target synergistic drug targets, while retaining the desirable features of typical monoclonal antibodies, such as standard manufacturing processes with comparable production yields, long serum half-life, the ability to mediate effector function and low immunogenicity risk.
One of the unique characteristics of the technology is that, in contrast to other bispecific platforms, Zymeworks’ Azymetric™ platform is compatible with alternative antigen binding formats, such as Fabs, scFvs, and VHHs) and cytotoxic conjugates.
In developing ZW49, scientists at Zymeworks used the company’s Azymetric™ platform in combination with ZymeLink™, a next-generation ADC platform technology which includes a suite of proprietary cytotoxins, stable linkers, and conjugation technologies compatible with traditional antibodies and proteins. This technology was created as a foundation for the development of multifunctional therapeutics designed to overcome the limitations of existing ADCs.
6th World ADC Awards
Each year the World ADC Awards recognizes innovation, leadership, and devotion in the development of antibody-drug conjugate research and development. The annual awards acknowledges anyone pushing the boundaries, dedicating their careers and companies to the pursuit of developing a novel way to fight cancer and hematological malignancies and showcases the extraordinary endeavors, teamwork and commercial acumen that has propelled the field to the forefront of cancer research today.
“The Finalists for 2019 reflects the exciting year we have seen for the ADC space with novel innovations and world class research truly accelerating the field,” noted Elayda Hearne, Program Director, World ADC.
“We are delighted to celebrate and highlight a spotlight on companies that demonstrate the dedication, leadership and innovation that exists in this crucial area of oncology therapeutics,” Hearne added.
