EMERYVILLE, Calif., May 06, 2021 (GLOBE NEWSWIRE) -- Gritstone bio, Inc. (Nasdaq: GRTS), a clinical-stage biotechnology company developing next generation cancer and infectious disease immunotherapies, today reported financial results for the first quarter ended March 31, 2021 and reviewed business highlights.
“The momentum we generated in the first quarter -- with the launch of two novel programs in a new therapeutic category of infectious disease, the execution of multiple collaborations with notable government, private and nonprofit institutions, and the continued advancement of our oncology clinical programs – reflects the significant interest in our innovative, antigen-directed clinical-stage immunotherapies,” said Andrew Allen, M.D., Ph.D., co-founder, president and chief executive officer of Gritstone. “We expect this activity level to extend into the rest of the year. We are continuing patient dosing and follow-up in our GRANITE program and will be submitting these data for presentation at ESMO. Additionally, we expect to have data from our CORAL COVID-19 program available later this year. Finally, we will be initiating multiple clinical studies in oncology and infectious disease in 2021.”
Key Accomplishments Neoantigen Oncology Programs
Continued enrolling and treating patients with advanced cancer in single-arm Phase 2 expansion cohorts with GRANITE, an individualized neoantigen immunotherapy, as a late-line therapy for metastatic microsatellite stable colorectal cancer (MSS-CRC), gastroesophageal (GEA) cancer and non-small cell lung cancer (NSCLC)
Continued enrolling and treating patients in single-arm Phase 2 expansion cohorts with version 1 (v1) of SLATE, a shared neoantigen immunotherapy
Infectious Disease Programs
Announced the launch of our CORAL COVID-19 program to develop a second-generation vaccine against SARS-CoV-2, the virus that causes COVID-19, with potential for both more durable protection and broader immunity against Spike and additional non-Spike antigens, compared with first-generation “Spike-only” vaccines which can be impacted by emerging variants of concern in Spike sequence
Began dosing volunteers in a Phase 1 CORAL clinical trial, sponsored by the National Institute of Allergy and Infectious Diseases (NIAID) and conducted through the Infectious Diseases Clinical Research Consortium (IDCRC)
Established a collaboration with Gilead Sciences (Gilead) to develop a vaccine-based immunotherapy as part of Gilead’s efforts to find a curative treatment for human immunodeficiency virus (HIV) infection, and received $60 million in proceeds as a part of the collaboration
Anticipated Remaining 2021 Milestones
Submit an abstract to the European Society for Medical Oncology (ESMO) conference in September 2021 to present GRANITE data, including longer-term follow-up of late-stage, advanced disease patients who remain in the Phase 1 study, in addition to preliminary data from the Phase 2 cohorts in the same disease context
Advance the SLATE program by initiating a study with the version two (v2) cassette optimized for KRAS neoantigens for patients with NSCLC, and sharing data from SLATE v1 cohorts in the third quarter of 2021
Initiate a company-sponsored COVID-19 clinical study in the third quarter of 2021, evaluating a novel vaccine containing Spike and other SARS-CoV-2 epitopes as a boost after first generation vaccination
Share NIAID-IDCRC Phase 1 COVID-19 vaccine data in the third quarter of 2021
Share initial COVID-19 vaccine boost data in the fourth quarter of 2021
Initiate two randomized Phase 2 trials of GRANITE in earlier-stage cancer patients in the second half of 2021
Launch a new SLATE program, centered on an undisclosed shared neoantigen, at the end of 2021
First Quarter 2021 Financial Results For the three months ended March 31, 2021, Gritstone reported net income of $7.9 million, compared to a net loss of $26.2 million for the three months ended March 31, 2020. The increase in net income was due to an increase in license fee revenue.
Collaboration and license revenue was $39.7 million for the three months ended March 31, 2021, compared to $1.3 million for the three months ended March 31, 2020. The increase was due to the license revenue associated with the Gilead Collaboration Agreement entered into in January 2021.
Total research and development expenses were $24.9 million for the three months ended March 31, 2021, compared to $22.5 million for the three months ended March 31, 2020. The increase was primarily attributable to an increase in milestone and license payments, as well as personnel-related expenses.
General and administrative expenses were $6.9 million for the three months ended March 31, 2021, compared to $5.5 million for the three months ended March 31, 2020. The increase was primarily attributable to an increase in outside professional services.
Cash, cash equivalents, marketable securities and restricted cash were $199.0 million as of March 31, 2021 compared to $172.1 million as of December 31, 2020.
About Gritstone Gritstone bio, Inc. (Nasdaq: GRTS), a clinical-stage biotechnology company, is developing the next generation of immunotherapies against multiple cancer types and infectious diseases. Gritstone develops its products by leveraging two key pillars—first, a proprietary machine learning-based platform, Gritstone EDGETM, which is designed to predict antigens that are presented on the surface of cells, such as tumor or virally-infected cells, that can be seen by the immune system; and, second, the ability to develop and manufacture potent immunotherapies utilizing these antigens to potentially drive the patient’s immune system to specifically attack and destroy disease-causing cells. The company’s lead oncology programs include an individualized neoantigen-based immunotherapy, GRANITE, and an “off-the-shelf” shared neoantigen-based immunotherapy, SLATE, which are being evaluated in clinical studies. Within its infectious disease pipeline, Gritstone is advancing CORAL, a COVID-19 program to develop a second-generation vaccine, with support from departments within the National Institutes of Health (NIH), the Bill & Melinda Gates Foundation, as well as a license agreement with La Jolla Institute for Immunology. Additionally, the company has a global collaboration for the development of a therapeutic HIV vaccine with Gilead Sciences. For more information, please visit gritstone.com.
