SOUTH SAN FRANCISCO, CA, June 3, 2024 – Electra Therapeutics, Inc., a clinical stage biotechnology company developing antibody therapies against novel targets for a broad range of immunological diseases and cancer, announced today the appointment of Graham Parry, PhD, as Chief Scientific Officer and Kim-Hien Dao, DO, PhD, as Chief Medical Officer. Both executives have deep experience in drug development and each have been instrumental in leading multiple drug candidates through clinical trials and toward regulatory approval.

“We are delighted to have such exceptional leaders as Graham and Kim-Hien join our management team at a time of great momentum for the company, with clinical proof-of-concept established for our lead candidate, ELA026,” said Kathy Dong, PharmD, MBA, President and Chief Executive Officer of Electra Therapeutics. “Graham’s scientific leadership across our cross-functional teams will be highly valued as we maximize the potential of ELA026 and pursue a broad range of opportunities to address unmet needs in immune-mediated diseases and cancer. Kim-Hien has demonstrated outstanding clinical and translational research expertise that will be instrumental in guiding ELA026 through the clinic as a first-in-class antibody therapy for patients with sHLH, a severe inflammatory disease with critical unmet needs and no approved treatment.”

Dr. Parry stated, “I am enthusiastic about Electra’s approach to combining rigorous research and novel biology to deliver new therapies to under-served patient populations. The opportunity to work alongside this outstanding team with such a clear and focused mission is truly a privilege.”

Dr. Graham Parry brings over 20 years of experience to the development of novel therapies for rare and life-threatening diseases. Prior to joining Electra, he served as Executive Vice President of Translational Sciences at Star Therapeutics where he worked across a range of

R&D programs to advance the development of novel treatments for multiple diseases. Previously, he served as Senior Vice President of Translational Sciences at Third Harmonic Bio, focused on treatments for allergic and inflammatory diseases, and as Vice President of Technical Operations at True North Therapeutics where he worked on the discovery and development of ENJAYMO®, a first-in-class inhibitor of the classical complement pathway approved for the treatment of cold agglutinin disease. Earlier in his career, he worked in drug development roles at iPierian in neurodegenerative diseases and Attenuon in cancer therapeutics, and as an assistant professor at The Scripps Research Institute. Dr. Parry earned his BSc at Brunel University and his PhD at the University of London.

Dr. Dao commented, “I am delighted to take on this role during such an exciting time at Electra as the company advances ELA026 as a promising new therapy for patients with sHLH who currently lack effective treatment options. I look forward to the work ahead to build on the encouraging data to date for ELA026 in sHLH as well as in additional indications, and to contribute to the company’s continued progress.”
