Zymeworks Inc. announced that it is strengthening its senior leadership team with the appointment of Paul Moore, Ph.D., as Chief Scientific Officer, reporting directly to the Chief Executive Officer. Dr. Moore brings more than 25 years of US-based experience in biologics drug discovery and development in biotechnology research. His career efforts have led to the discovery and development of a range of FDA-approved and clinical-stage biologics for patients with difficult-to-treat cancers and autoimmune conditions.

Dr. Moore's anticipated start date is July 18, 2022. Immediately prior to joining Zymeworks, Dr. Moore served as Vice President, Cell Biology, and Immunology at MacroGenics, heading a team of approximately 50 researchers focused on developing antibody-based therapeutics, including numerous bispecific antibodies and ADCs. During his time at MacroGenics, Paul worked on the development of numerous clinical stage compounds, including retifanlimab (anti-PD-1 mAb), teplizumab (anti-CD3 mAb for Type I diabetes), margetuximab (anti-HER2 mAb), enoblituzumab (anti-B7-H3 mAb), various CD3 based bispecifics including flotetuzumab (CD123 x CD3), bispecifics targeting multiple checkpoints tebotelimab (PD-1xLAG-3) and lorigerlimab (PD-1xCTLA-4), CD32BxCD79B bispecific for autoimmunity and ADC molecules targeting B7-H3 or ADAM-9. Dr. Moore worked on scientific collaborations with a range of pharmaceutical partners, including Pfizer, Servier, Gilead, Takeda, Janssen, Roche and Zai Labs.

Prior to joining MacroGenics, he was Director of Cell Biology at Celera where he oversaw research efforts to develop novel antibody-based therapeutics. Early in his career, he served as Director of Lead Product Development at Human Genome Sciences (HGS), including managing genomic-based target discovery programs that led to the discovery, development, approval, and commercialization of Benlysta (belimumab) for the treatment of systemic lupus erythematosus. In 2012, GlaxoSmithKline (GSK) acquired HGS for $3.6 billion, and GSK reported sales of approximately $0.75 billion for Benlysta during 2021.

In 1991, Dr. Moore received a Ph.D. in molecular genetics from the University of Glasgow. He has an extensive research record co-authoring over 75 peer-reviewed manuscripts and is a named co-inventor on over 50 issued US patents. Dr. Moore's appointment builds on the Company's new focus on extending its leadership in the biopharmaceutical industry with a renewed organization and expanding pipeline of product candidates with the potential to make a significant difference for patients around the world with difficult-to-treat cancers.

Dr. Moore will be responsible for advancing Zymeworks' cornerstone multispecific antibody and ADC programs to clinical studies and overseeing the Company's Early Research and Development Group. Paul's experience in forming and managing partnerships and collaborations with pharmaceutical companies will be helpful as Zymeworks integrates such partnerships and collaborations into its product development strategy. Zymeworks' Research Leadership Team consists of four research team leads, reporting to Dr. Moore, in ADC Therapeutic Development Technology and Preclinical Programs, and Multispecific Antibody Therapeutics Technology and Preclinical Programs: Stuart Barnscher, Director, ADC Research: Mr. Barnscher leads the discovery and development of novel ADC technologies and drug candidates with a focus on in vitro and in vivo pharmacology.

He was instrumental in the development of the two ADC drug-linker technologies associated with Zymeworks' ZymeLink™ platform and, since joining Zymeworks in 2016, he has made significant contributions to the design and development of ZW49. Mr. Barnscher obtained his undergraduate degree in biochemistry from the University of British Columbia. Jamie Rich, Ph.D., Director, ADC Research: Dr. Rich focuses on discovery and pipeline applications of new ADC technologies.

Since joining Zymeworks in 2016, he has contributed to ZW49, led several pipeline programs, and overseen development of a Topoisomerase 1 inhibitor ADC platform. Dr. Rich is a co-inventor of multiple technologies associated with Zymeworks' ZymeLink™ platform. He received a Ph.D. from the University of Alberta and held a postdoctoral fellowship at the University of British Columbia.

Thomas Spreter Von Kreudenstein, Ph.D., Director, Protein Engineering: Dr. Spreter Von Kreudenstein leads protein engineering and multispecific antibody technologies at Zymeworks. Since joining Zymeworks in 2010, he was one of the lead inventors of Zymeworks' Azymetric™ technology and has led immune-oncology research programs at the Company, including T-cell engager and cytokine fusion programs. Dr. Spreter Von Kreudenstein received his Ph.D. from the University of Berlin and held a postdoctoral fellowship at the University of British Columbia. Nina Weisser, Ph.D., Director, Multispecific Research: Dr. Weisser leads the development of multispecific antibody therapeutics with a focus on mechanism of action studies.

Since joining Zymeworks in 2012, she has led several research programs, including zanidatamab from discovery to early development. Dr. Weisser received her Ph.D. from the University of Guelph and held a post-doctoral fellowship at the National University of Ireland. Oversight of the Company's research strategy is provided by a committee of the Board of Directors comprised of Dr. Natalie Sacks, Dr. Kenneth Hillan and Dr. Kelvin Neu.

The Company also intends to reset the membership of its Scientific Advisory Board in conjunction with the Early Research and Development investor day to be held during the fourth quarter of 2022.
