SOUTH SAN FRANCISCO, Calif., March 21, 2022 – Graphite Bio, Inc. (Nasdaq: GRPH), a clinical-stage, next-generation gene editing company focused on developing therapies that harness targeted gene integration to treat or cure serious diseases, today reported recent business progress and fourth quarter and fiscal year 2021 financial results.
“2021 was a pivotal year in our company’s history as we established ourselves as a public company and initiated the clinical trial for our lead candidate, GPH101 for sickle cell disease. In 2022, we remain focused on advancing our research and development priorities, in particular the execution of our Phase 1/2 CEDAR clinical trial of GPH101. We continue to work toward demonstrating that our unique gene correction approach to reduce sickle hemoglobin production and restore adult hemoglobin expression has the potential to achieve the ideal genetic outcome and provide a definitive cure for patients with sickle cell disease,” said Josh Lehrer, M.D., M.Phil., chief executive officer of Graphite Bio.
“Over the course of this year, we look forward to sharing more information about our research programs, including GPH102, our differentiated gene replacement program for beta-thalassemia,” Lehrer continued. “With our updated pipeline priorities, our programs now even more closely align with our goal of transforming the gene therapy treatment paradigm – from how we develop and manufacture these individualized therapies to how we deliver them to patients. Our mission is to make ‘one dose, one cure’ a reality for as many patients as possible with serious diseases and inadequate treatments.”
Program Updates
GPH101 for Sickle Cell Disease
|
|
• |
Continued patient enrollment in the Phase 1/2 CEDAR clinical trial of GPH101, an investigational therapy designed to directly correct the genetic mutation responsible for sickle cell disease (SCD), at multiple sites across the United States. Due to impacts of the recent COVID-19 Omicron variant surge on patients and site resources and operations, the company now plans to dose its first patient in the second half of 2022, with initial proof-of-concept data anticipated in 2023. |
|
|
• |
Presented a trial-in-progress poster about the CEDAR trial at the 63rd American Society of Hematology (ASH) Annual Meeting & Exposition and hosted an event featuring a discussion among key opinion leaders about how the company’s differentiated gene correction approach using GPH101 could lead to curative outcomes for SCD patients. |
|
|
• |
Presented preclinical data for GPH101 at the 49th Annual Sickle Cell Disease Association of America’s National Convention. These data, which support the ability of the company’s gene editing platform to precisely and efficiently correct the underlying SCD-causing mutation to reduce sickle hemoglobin production and restore adult hemoglobin expression to levels that are considered potentially curative, are foundational to the company’s SCD program and support the evaluation of GPH101 in the CEDAR trial. |
Additional R&D Updates
Prioritized and advanced research programs to maximize the capabilities of the company’s next-generation gene editing platform and significantly impact patient outcomes, including:
|
|
• |
Announced a new research program, GPH102 for the treatment of beta-thalassemia, a genetic blood disorder that reduces the production of hemoglobin and leads to severe anemia and, in severe cases, transfusion dependency. Using the company’s gene replacement technology, GPH102 is designed to replace the entire mutated beta-globin gene and restore adult hemoglobin expression to levels similar to individuals who do not have disease or have beta-thalassemia trait. The company expects to submit an IND for this program by mid-2024, pending feedback from health authorities. |
|
|
• |
Disclosed an early-stage research program for the treatment of alpha-1 antitrypsin (AAT) deficiency, a severe inherited genetic disorder that can cause progressive lung and liver disease. The program leverages the company’s targeted gene insertion technology to permanently increase AAT protein production, offering a potentially differentiated approach to treating the disease. The company expects to provide updates about this program over the course of 2022. |
|
|
• |
Reassessed the development strategy for GPH301 for Gaucher disease. The company believes GPH301 can have the greatest impact as a potential one-time curative treatment and alternative to chronic enzyme replacement therapy in patients with Type 1 Gaucher disease, when combined with a potential NGTC regimen. The company is assessing a strategy and timeline for GPH301 to enter clinical testing with an NGTC regimen. |
Business Updates
|
|
• |
Appointed Alethia Young as chief financial officer. Ms. Young has more than 20 years of experience in healthcare and biotechnology equity research and investing. She joins the company from Cantor Fitzgerald, where she served as senior biotechnology analyst and head of research, managing the equity research department covering companies across the biotechnology industry. |
|
|
• |
Welcomed Christine Garrett, Ph.D., as chief of staff and senior vice president of operations. Dr. Garrett has more than 20 years of industry experience leading cross-functional teams comprised of research, development and commercial leaders across various phases of drug development. |
|
