Gritstone bio, Inc. Announces Encouraging Updated Interim Phase 2 Data from Ongoing Phase 2 Study Evaluating GRANITE Gritstone bio, Inc. announced encouraging updated interim Phase 2 data from the ongoing Phase 2 study evaluating GRANITE, its individualized neoantigen targeting immunotherapy, in first-line microsatellite stable colorectal cancer (MSS-CRC). The ongoing randomized, controlled study is evaluating the clinical benefit of maintenance therapy with GRANITE (GRT-C901/GRT-R902) in combination with immune checkpoint inhibitors (ICI) in addition to fluoropyrimidine/bevacizumab versus fluoropyrimidine/bevacizumab alone. Key Findings from an Updated Interim Phase 2 Analysis in Front-Line Metastatic MSS-CRC: Data cut as of October 17, 2024 vs. August 19, 2024. An updated October analysis of progression-free survival (PFS) per RECIST v1.1 included an additional two months of follow-up. 28% (11/39) GRANITE and 13% (4/30) of control patients remain on study and free of progression vs. 33% (13/39) GRANITE and 23% (7/30) of control patients from August analysis; the majority of GRANITE patients still on study have undetectable ctDNA using Gritstone’s high-sensitivity, tumor-informed assay. Clinical benefit improved compared to previous analysis in patients with low and high disease burden (based on ctDNA levels). Clinical benefit was most notable in patients with low disease burden at study entry. Low baseline ctDNA levels (eg at study entry) is a likely prognostic and predictive factor. Overall survival data remain immature, with mature data expected in the second half of 2025. GRANITE continues to demonstrate a favorable safety and tolerability profile. Tillkännagivande • Oct 24

New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: €6.70m (US$7.33m) This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$112m free cash flow). Shares are highly illiquid. Earnings are forecast to decline by an average of 8.0% per year for the foreseeable future. Market cap is less than US$10m (€6.70m market cap, or US$7.33m).

Gritstone Bio Announces Interim Phase 2 Data for Granite Individualized Neoantigen Targeting Immunotherapy in Frontline Metastatic Microsatellite Stable Colorectal Cancer Gritstone bio, Inc. announced encouraging interim Phase 2 data from the ongoing Phase 2 study evaluating GRANITE, its individualized neoantigen targeting immunotherapy, in frontline microsatellite stable colorectal cancer (MSS-CRC). The randomized, controlled study is designed to evaluate the clinical benefit of maintenance therapy with GRANITE (GRT-C901/GRT-R902) in combination with immune checkpoint inhibitors in addition to fluoropyrimidine/bevacizumab versus fluoropyrimidine/bevacizumab alone. Overall progression-free survival (PFS) data show an encouraging benefit for GRANITE patients (HR=0.79 [95% CI, 0.42-1.50]). As expected, the greatest benefit was observed in the 50% of patients with lower disease burden at study entry, as measured by circulating tumor DNA (ctDNA) at study baseline. (HR=0.62 [95% CI, 0.23-1.70]). Continued follow-up is needed to fully assess GRANITE effects and determine whether a plateau of improved PFS (indicating durable clinical benefit) is achieved. The most recent ctDNA assessments for the 20 patients who remain without disease progression (per RECIST) were supportive of potential benefit from treatment with GRANITE: 12 of 13 GRANITE patients had stable ctDNA titers below the assay limit of quantitation (LOQ); 4 of 7 control patients exhibited the same characteristic. Concurrently, Gritstone announced that it has engaged Raymond James as its financial advisor to support the Company in exploring and reviewing potential value-maximizing strategies. Gritstone does not intend to discuss or disclose further developments regarding the exploration of strategic alternatives unless and until its Board of Directors has approved a definitive action or otherwise determined that further disclosure is appropriate or required by law. 104 patients were randomized 1:1 in the study: 69 patients (39 GRANITE arm, 30 control arm) are included in the treated analysis below. Demographics and clinical characteristics were balanced between arms (stage, sidedness, presence of liver metastases), with the vast majority (80%) of patients having liver metastases in the treated analysis. Thirty-five patients did not advance to study treatment after oxaliplatin, most commonly due to withdrawing consent (n=15), disease progression (n=8), and other reasons (n=12) (12 in GRANITE arm; 23 in control arm). Interim data demonstrated an emerging PFS benefit to all GRANITE recipients (study not statistically powered for PFS) 21% relative risk reduction of progression or death with GRANITE vs. standard of care (SOC) control in all treated population (HR=0.79 [95% CI, 0.42-1.50]) 33% (13/39) GRANITE and 23% (7/30) of control patients remain on study and free of progression Last ctDNA assessment is below the assay LOQ in 12/13 GRANITE and 4/7 control patients Clinical benefit was most notable in patients with low disease burden (defined as patients with ctDNA equal to or below the trial population median value at study entry) 38% relative risk reduction of progression or death with GRANITE vs. SOC control with low ctDNA subgroup (HR=0.62 [95% CI, 0.23-1.70]) Low baseline ctDNA is a likely prognostic and predictive factor Immune data were consistent with clinical activity Functional neoantigen-specific T cells were observed in all 16/16 GRANITE patients tested by ELISPOT Association of PFS and peak ex vivo ELISPOT responses was apparent, suggesting that ex vivo ELISPOT may be a surrogate for PFS GRANITE demonstrated a favorable safety and tolerability profile No patients discontinued study treatment due to an adverse event (AE) Common adverse events were the mild systemic and local effects associated with any potent vaccine, i.e. transient flu-like illness One treatment-related serious AE (fatigue) occurred in the GRANITE arm (patient continued GRANITE treatment without recurrence upon recovery) Gritstone plans to review the PFS data with FDA in the coming months and agree on next steps to advance GRANITE, including a potential Phase 2 or 3 trial using ctDNA levels as eligibility criteria.

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 0.3% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Shares are highly illiquid. Earnings are forecast to decline by an average of 0.3% per year for the foreseeable future. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$184m net loss in 3 years).

Nature Medicine Publishes Interim Results from Gritstone Bio's Phase 1/2 Study of "Off-The-Shelf" Neoantigen Vaccine Platform (SLATE) Gritstone bio, Inc. announced that a paper detailing the development of its “off-the-shelf” neoantigen platform, SLATE, recently published in Nature Medicine. The paper, “A shared neoantigen vaccine combined with immune checkpoint blockade for advanced metastatic solid tumors: phase 1 trial interim results,” describes a novel immunodominance hierarchy of tumor neoantigens (including KRAS) that Gritstone discovered in Phase 1 translational studies and leveraged to develop SLATE-KRAS, a “pure” KRAS-directed candidate that demonstrated superior immunogenicity to the initial version in a subsequent Phase 2 study and is currently being evaluated in a novel cell therapy-vaccine combination study run by Steven A. Rosenberg of the National Cancer Institute (NCT06253520). Results from the SLATE 1/2 Study: The data published in Nature Medicine report the interim safety, tolerability and immunogenicity results from the Phase 1 portion of the Phase 1/2 clinical trial (NCT03953235) assessing the off-the-shelf vaccine SLATEv1 in patients with advanced/metastatic solid tumors. SLATEv1 utilizes a heterologous ChAd68 followed by samRNA-based vaccine regimen encoding 20 shared neoantigens targeting multiple recurrent mutations in several oncogenes, including KRAS, TP53, BRAF and CTNNB1. Neoantigens were identified using Gritstone bio’s proprietary neoantigen prediction platform, EDGETM, and selected based on shared mutation and matched HLA frequencies in patient populations with solid tumors. Biased T cell responses toward HLA-matched TP53 neoantigens encoded in the vaccine relative to KRAS neoantigens expressed by the patients’ tumors, indicated a previously unknown hierarchy of neoantigen immunodominance that may impact the therapeutic efficacy of multi-epitope shared neoantigen vaccines. These data led to the development of SLATE-KRAS, a vaccine focused on KRAS-derived neoantigens that subsequently was evaluated in the Phase 2 portion of the clinical study. Initial Phase 2 data suggesting an increased vaccine induced T cell response were presented in September 2022. New Risk • Apr 12

Gritstone Bio Announces Update to Comparative Phase 2B Covid-19 Clinical Trial Gritstone bio, Inc. announced that it is now preparing to launch the Phase 2b head-to-head trial of its next-generation COVID-19 vaccine in the Fall of 2024 rather than 1Q24. This is to allow use of fully GMP-grade raw materials in the vaccine, which is expected to increase the regulatory utility of the trial. This project has been supported in whole or in part with federal funds from the U.S. Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50123C00062. The CORAL-BARDA study is an intended 10,000 participant, randomized Phase 2b double-blinded study to compare the efficacy, safety, and immunogenicity of Gritstone bio’s next-generation COVID-19 vaccine candidate with an approved COVID-19 vaccine. The goal of this study is to determine whether Gritstone bio’s next-generation vaccine candidate, a self-amplifying mRNA (samRNA) vaccine, can provide better and longer protection against COVID-19 than the currently FDA-approved vaccines. Self-amplifying mRNA (samRNA) is rapidly emerging as a well-tolerated, scalable and widely-applicable platform technology which can be used to develop multiple vaccines simply by changing the sequence of the antigen (the target of the immune system) that is encoded in the vector RNA and delivered in a lipid nanoparticle. Like traditional mRNA vaccines, samRNA vaccines use the host cell’s translation system to convert mRNA to protein target antigens in order to stimulate immunity. Unlike traditional mRNA, samRNA creates multiple copies of the antigen RNA once in the cell, potentially leading to extended duration and magnitude of antigen expression. Gritstone designs novel immunogens, the vaccine regions encoding virus antigens, and includes both Spike antigen (similar to first-generation COVID-19 vaccines) and evolutionarily conserved, non-Spike antigens likely to drive T cell responses in its next-generation COVID-19 vaccines. Potential benefits of this samRNA “Spike plus” approach include (1) strong and durable induction of neutralizing antibodies to Spike, (2) broad and durable T cell immunity (CD4+ and CD8+) to multiple viral proteins, (3) potency at lower doses (dose sparing), and (4) refrigerator stability.

Gritstone bio, Inc. Announces Updated Overall Survival Results from Granite Phase 1/2 Study and Poster At Sitc 2022 Gritstone bio, Inc. announced updated overall survival (OS) results from its Phase 1/2 study evaluating GRANITE, an individualized vaccine-based immunotherapy, for the treatment of advanced solid tumors. These results, along with results from a clinicopathologic analysis of metastatic MSS-CRC patients with and without a molecular response, will be presented via a poster at the Society for Immunotherapy of Cancer (SITC) 37th Annual Meeting. The Phase 1/2 study is evaluating the safety, immunogenicity, and clinical activity of GRANITE in combination with PD-1 checkpoint inhibitor, nivolumab and subcutaneous anti-CTLA-4 antibody ipilimumab in advanced solid tumors. This study enrolled and treated 29 patients with previously treated, metastatic solid tumors including patients with colorectal cancer, gastroesophageal adenocarcinoma, and non-small cell lung cancer. Of 13 patients with MSS-CRC, 6 experienced a molecular response defined as =30% reduction in circulating tumor DNA (ctDNA) and continue to have an overall survival advantage compared to those patients without a molecular response. Updated OS data from GRANITE Phase 1/2: 6 of 13 treated patients with MSS-CRC had a molecular response and the observed median overall survival in this group will now exceed 22 months (median OS not yet reached versus 7.8 months in those without a molecular response). This compares to a median overall survival not yet reached and exceeding 18 months as reported in May 2022. Clinicopathologic characteristics from GRANITE Phase 1/2: 4 of 6 patients with molecular response had liver metastasis. All patients had PD-L1 expression <1% and low levels of IFNg-related gene expression. Median tumor mutational burden was 2.9 and 3.6 mutations/MB in those with and without molecular response, respectively. Reported Earnings • Nov 05

Gritstone bio, Inc. Presents Positive Initial Phase 2 Data in Late-Line Solid Tumor Patients Treated with KRAS-Directed Immunotherapy at ESMO 2022 Gritstone bio, Inc. presented positive safety, immunogenicity, and early efficacy data from its SLATE program, an off-the-shelf vaccine program targeting shared neoantigens, in combination with immune checkpoint blockade, for patients with advanced solid tumors at the 2022 European Society for Medical Oncology (ESMO) Congress. The presentation included initial data with SLATE-KRAS, a shared mutant KRAS-specific neoantigen vaccine candidate, in addition to updated data using the first version of the vaccine candidate (SLATE v1), which contains both KRAS and non-KRAS neoantigens. The data were presented by Chrisann Kyi, MD of Memorial Sloan Kettering Cancer Center during a mini-oral presentation on Saturday, September 10, 2022. This Phase 1/2 study (NCT03953235) is evaluating the safety, immunogenicity, and early clinical activity of both SLATE v1 and SLATE-KRAS in combination with PD-1 checkpoint inhibitor Opdivo® (nivolumab) and subcutaneous anti-CTLA-4 antibody Yervoy® (ipilimumab) in patients with metastatic solid tumors harboring select KRAS mutations. SLATE v1 targets 20 shared neoantigens from KRAS, TP53, ß-catenin, and BRAF genes, while SLATE-KRAS is optimized to exclusively target KRAS neoantigens including the highly prevalent G12C, G12D, G12V and Q61H driver mutations. Gritstone developed the KRAS-optimized candidate (SLATE-KRAS) after initial testing of SLATE v1 suggested non-KRAS neoantigens (including TP53) might exhibit immunodominance over KRASmut, thus attenuating efficacy. A total of 38 patients with advanced solid tumors have been enrolled in the study across cohorts using SLATE v1 (n=26) or SLATE-KRAS (n=12). The majority of patients enrolled (31/38) had either advanced non-small cell lung cancer (NSCLC; n=18) or microsatellite stable colorectal cancer (MSS-CRC; n=13). In the Phase 1/2 study, both SLATE-KRAS and SLATE v1 vaccine-based immunotherapies demonstrated: A favorable safety and tolerability profile Majority of treatment-related adverse events were Grade 1/2, with three = Grade 3 events reported with SLATE v1 and no = Grade 3 events reported with SLATE-KRAS Consistent and potent immunogenicity Induction of KRAS-specific CD8+ T cells: 55% of patients treated with SLATE-KRAS versus 31% of patients treated with v1 (by ex vivo ELISpot assay) Early objective evidence of efficacy as measured by reduction in ctDNA (molecular response) 39% (7/18) molecular response rate in evaluable patients with MSS-CRC and NSCLC. Evaluable subjects had detectable KRASmut ctDNA at baseline and a post-baseline sample. All patients with NSCLC had progressed on prior (chemo)immunotherapy. In 18 patients with NSCLC, a molecular response was correlated with extended OS. NSCLC patients with a molecular response demonstrated a median OS (9.6 months) more than double those without (4.5 months). The OS analysis included patients with no detectable ctDNA or no data at baseline (n=7) in the no molecular response group. At the time of data cut-off, there were insufficient evaluable patients in the CRC patient set to support a similar analysis. Additionally, treatment with SLATE-KRAS induced a molecular response (normalization of tumor markers and reduction in ctDNA) and clinical benefit were observed in a patient with Stage IV KRAS G12V mutant MSS-CRC and multiple liver metastases who had progressed on two prior therapies.

Gritstone bio, Inc. Publishes Interim Results from Gritstone bio’s Phase 1/2 Study of GRANITE, Individualized Neoantigen Vaccine for Solid Tumors Gritstone bio, Inc. announced that interim results from the Phase 1/2 trial of GRANITE, its individualized, vaccine-based immunotherapy candidate for solid tumor cancers, were published on August 15, 2022 in Nature Medicine. The paper, “Individualized, heterologous chimpanzee adenovirus and self-amplifying mRNA neoantigen vaccine for advanced metastatic solid tumors: phase 1 trial interim results,” details results demonstrating that GRANITE generated strong, persistent, and functional tumor-specific CD4+ and CD8+ T cell responses that have potential broad applicability across a range of disease settings. The published data were originally presented at the European Society for Medical Oncology (ESMO) Congress 2021, and acted as the basis for launching two randomized, controlled studies of GRANITE, including a Phase 2/3 trial that has registrational intent (GRANITE-CRC-1L). Since initiation of the Phase 1/2 study, Gritstone has followed study participants and observed increased overall survival (OS) in colorectal cancer (CRC) patients who demonstrated a molecular response (measured by a reduction in circulating tumor DNA [ctDNA] levels from baseline) versus those who did not. As of May 2022, median OS of this subgroup (treated third-line CRC patients who demonstrated a molecular response) exceeded 18 months with the median not yet reached. This compares to median OS of 7.8 months for patients who did not demonstrate a molecular response, results which are generally consistent with extensive prior data from patients receiving various third-line therapies. Baseline characteristics of these two patient populations are similar. The Phase 1/2 study remains ongoing. GRANITE is now being evaluated in two randomized studies in earlier-stage disease; 1) GRANITE-CRC-1L (NCT05141721), a Phase 2/3 trial in newly diagnosed metastatic, microsatellite-stable colorectal cancer (MSS-CRC) that has registrational intent. The first patient was treated in this study in July 2022, and initial results from this study are expected in the second half of 2023. 2) GRANITE-ADJUVANT (NCT05456165), a phase 2 study in patients with high-risk stage II/III colon cancer who are ctDNA+ after definitive surgery. Gritstone’s neoantigen-based immunotherapies are engineered to elicit a significant T cell response (particularly CD8+ cytotoxic T cells) against mutation-derived tumor-specific neoantigens (TSNA), that Gritstone identifies using its proprietary artificial intelligence platform, EDGE™. GRANITE is an individualized neoantigen-based immunotherapy and uses a priming adenoviral vector (GRT-C901) and self-amplifying mRNA vector (GRT-R902) to deliver personalized immunotherapy containing the relevant neoantigens. GRANITE was granted Fast Track designation by the U.S. Food and Drug Administration for the treatment of MSS-CRC. Tillkännagivande • Aug 11

Gritstone Announces Results from Preclinical Study of Its Self-Amplifying Mrna (Samrna) Vaccine Against Sars-Cov-2 Published in Nature Communications Gritstone bio, Inc. announced results from a preclinical study evaluating a self-amplifying mRNA (samRNA) vaccine candidate against SARS-CoV-2 were published in Nature Communications, in an article titled “Low-dose self-amplifying mRNA COVID-19 vaccine drives strong protective immunity in non-human primates against SARS-CoV-2 infection”. The results of the study, which were previously pre-printed in bioRxiv, show that the samRNA vaccine candidate induced broad and potent neutralizing antibodies and T cell immune responses following administration to non-human primates (NHP) at low doses, and that these immune responses were protective against SARS-CoV-2 challenge. Since the pre-publication of these data in November 2021, Gritstone disclosed initial results from a Phase 1 study of a samRNA vaccine candidate demonstrating similar outcomes against SARS-CoV-2. The company is currently evaluating samRNA vaccines for coronaviruses and other infectious diseases. Gritstone is currently evaluating four distinct SARS-CoV-2 product candidates across three different Phase 1 clinical trials containing various Spike variants plus additional highly conserved non-Spike T cell epitope sequences (and also full-length nucleocapsid) within its CORAL program. These studies include homologous and heterologous prime-boost regimens. All three of these studies are ongoing, and data from all are expected during the second half of 2022.

Gritstone Bio, Inc. Announces Positive Clinical Results from First Cohort of A Phase 1 Study (CORAL-BOOST) Evaluating A T Cell-Enhanced Self-Amplifying mRNA (SamRNA) Vaccine Against COVID-19 Gritstone bio, Inc. announced positive Phase 1 clinical data from the first cohort (10 µg dose of CORAL self-amplifying mRNA (samRNA) vaccine) of its CORAL-BOOST study, demonstrating both strong neutralizing antibody responses to Spike and robust CD8+ T cell responses. Recognizing the increased focus on T cell immunity as a key source of protection against current and future Spike variants, Gritstone’s CORAL program is developing a second-generation COVID-19 vaccine designed to drive both robust neutralizing antibodies and induce broad CD8+ T cell immunity. CORAL-BOOST, one of four trials in the company’s CORAL program, is evaluating the safety, reactogenicity, and immunogenicity of a samRNA vaccine directed against Spike and highly conserved non-Spike T cell epitopes (TCE) as a booster against SARS-CoV-2 in healthy adults =60 years (n=20 at two dose levels) who previously received two doses of AstraZeneca's first-generation COVID-19 vaccine AZD1222 (Vaxzevria). Results from First Cohort: A single 10 µg dose of the CORAL program’s samRNA vaccine administered to healthy adults =60 years (n=10) at least 22 weeks after two-dose series of Vaxzevria induced: New CD8+ T cell responses across a wide set of non-spike epitopes, including many validated T cell targets in convalescent individuals, demonstrating the potential for variant-proof immunity. Proportion of responses to TCE targets assessed by ELISpot: 36% Nucleoprotein (N), 22% Membrane (M) and 42% ORF3a. A boost to pre-existing T cell responses to Spike epitopes believed to be additive to antibody-based clinical protection conferred by Spike-dedicated vaccines: 120 at peak treatment day vs. 55 at pre-boost (Spot-forming units per 106 cells; assessed by IFNy ELISpot). Broad and potent neutralizing antibodies against SARS-CoV-2 Spike protein, at levels consistent with published data from higher doses of first-generation mRNA vaccines in a similar clinical context (COV-BOOST study; Munro et al., Lancet 2021). 2,370 Geomean ID50 titer values observed at day 29 against Wild Type variant vs. 108 at treatment day 1 (approx. 20-fold increase), 503 Geomean ID50 titer values observed at day 29 against Beta variant vs. 50 at treatment day 1 (approx. 10-fold increase) and 525 Geomean ID50 titer values observed at day 29 against Delta variant vs. 69 at treatment day 1 (approx. 8-fold increase) CORAL’s samRNA vaccine was well-tolerated and demonstrated a favorable safety profile with no grade 3/4 adverse events or unexpected reactogenicity or safety events in ten healthy adults =60 years. The CORAL-BOOST Phase 1 study is ongoing in the United Kingdom and has now dose escalated as planned to a 30 mg dose. Based on these positive Phase 1 data, Gritstone is amending this trial to increase enrollment to 120 subjects and evaluate the addition of a second samRNA-Spike-TCE dose, potentially enabling more rapid advancement into a pivotal study. Immunogenicity and reactogenicity data for additional cohorts is anticipated in coming months. Tillkännagivande • Dec 01
Gritstone bio, Inc Announces Omicron Variant of SARS-CoV-2 has Minimal Impact on the T Cell Epitopes (Targets) Contained within Gritstone’s Self-Amplifying mRNA COVID-19 Vaccines Gritstone bio, Inc. announced that the SARS-CoV-2 T cell epitopes (TCEs) administered within its self-amplifying mRNA (SAM) COVID-19 vaccines are minimally impacted by mutations found within the Omicron (B.1.1.529) variant, reinforcing the platform’s potential to address emerging variants of concern. The recently described Omicron variant, first identified in South Africa on November 9, 2021, was designated a Variant of Concern (VOC) by the World Health Organization (WHO) on November 26, 2021. Early evidence suggests that Omicron carries an increased risk of re-infection, and sequence analysis has revealed many mutations in Spike, including both the N terminal domain (NTD) and receptor binding domain (RBD), which may reduce clinical effectiveness of existing vaccines and/or therapeutic antibodies. Gritstone’s CORAL program is a second-generation SARS-CoV-2 vaccine platform delivering a stabilized Spike protein and highly conserved TCEs derived from other SARS-CoV-2 viral genes, offering the potential for more durable protection and broader immunity against SARS-CoV-2 variants. Delivery vectors can comprise self-amplifying mRNA (SAM), a chimpanzee adenovirus (ChAd), or both (mix-and-match). Sequence analysis suggests that Gritstone’s TCEs are minimally impacted by Omicron. Specifically, of the 146 non-Spike TCE delivered within Gritstone's vaccine currently in clinical trials in the UK and US, only 3 (~2%) are impacted by Omicron. Similar minimal impact of Omicron is observed in two new vaccine TCE constructs expected to enter clinical trials in South Africa before year end. Tillkännagivande • Sep 21
Gritstone Announces Dosing of First Volunteer in Trial Evaluating Self-Amplifying mRNA as a COVID-19 Vaccine Booster and Immunogenicity Enhancer Gritstone bio, Inc. announced that the first volunteer has been dosed in a Phase 1 trial evaluating the ability of GRT-R910, a self-amplifying mRNA (SAM) second generation SARS-CoV-2 vaccine to boost and expand the immunogenicity of first-generation COVID-19 vaccines in subjects 60 years of age or older. This single-center study is being conducted in collaboration with The University of Manchester and Manchester University NHS Foundation Trust in the United Kingdom. GRT-R910 is part of Gritstone’s CORAL program, a second-generation COVID-19 vaccine platform that uses a SAM vector formulated with lipid nanoparticles to deliver a broad set of antigens against SARS-CoV-2 that includes both stabilized spike protein and highly conserved viral protein regions containing T cell epitopes. By virtue of self-amplification, extended duration and magnitude of antigen production with SAM vaccines may offer the opportunity of lowering vaccine doses or eliminate the need for repeat administrations, and has potential to safely elicit strong, durable and broad immune responses across SARS-CoV-2 variants.

Gritstone Oncology, Inc. Advances Development of Second Generation Vaccine Against SARS-CoV-2 Gritstone Oncology, Inc. announced that it is advancing development of a second generation vaccine against SARS-CoV-2, the virus that causes COVID-19, with potential for both prolonged protection and potency against Spike mutants. Gritstone and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have entered into a clinical trial agreement to initiate clinical testing. A Phase 1 clinical trial, expected to be conducted through the NIAID-supported Infectious Diseases Clinical Research Consortium (IDCRC), is in development. The Bill & Melinda Gates Foundation (Gates Foundation) is supporting the preclinical evaluation of the vaccine. Through a license agreement with the La Jolla Institute for Immunology (LJI), one of the leading global organizations dedicated to studying the immune system, Gritstone has access to validated SARS-CoV-2 epitopes that have been identified through LJI’s studies of hundreds of patients recovering from COVID-19. Using these epitopes and the company’s proprietary Gritstone EDGETM and vaccine platform technologies, Gritstone is developing a novel vaccine against COVID-19, containing Spike (similar to first generation vaccines) but also additional viral epitopes that offer good targets for T cell immunity. Gritstone uses both self-amplifying mRNA and adenoviral vectors to deliver the SARS-CoV-2 viral antigens. The vaccine may have pan-SARS/coronavirus potential to protect against future coronavirus pandemics. The company has received a grant from the Gates Foundation to support the preclinical evaluation of the vaccine. NIAID is supporting development of the Phase 1 clinical trial through the IDCRC.

Gritstone Oncology, Inc. Advances into Phase 2 Expansion Cohorts for its Personalized Neoantigen Immunotherapy GRANITE and its Off-the-Shelf Neoantigen Immunotherapy SLATE Gritstone Oncology, Inc. announced that it has begun dosing patients in the Phase 2 expansion cohorts of the Phase 1/2 clinical studies for GRANITE and SLATE, its neoantigen-based immunotherapies. The Phase 2 portion of the GRANITE Phase 1/2 study (GO-004) includes a cohort for patients with microsatellite stable colorectal cancer (MSS CRC) who have progressed on FOLFOX/FOLFIRI therapy and a second cohort for patients with gastro-esophageal cancer (GEA) who have progressed on chemotherapy. GRANITE was granted Fast Track designation by the U.S. Food and Drug Administration for the treatment of MSS CRC. In the Phase 2 part of the SLATE Phase 1/2 study (GO-005), the company has begun enrolling non-small cell lung cancer patients with relevant KRAS mutations who have progressed on prior immunotherapy, and patients with tumors where a relevant TP53 mutation exists. Gritstone’s neoantigen-based immunotherapies are engineered to elicit a significant T-cell response (particularly CD8+ cytotoxic T cells) against mutation-derived tumor-specific neoantigens, or TSNA, that are identified by the company using its proprietary Gritstone EDGETM artificial intelligence platform and tumor HLA peptide sequencing. Data demonstrating the neoantigen identification capabilities of EDGE were published in Nature Biotechnology. GRANITE is Gritstone’s personalized immunotherapy that consists of two components: first, a priming adenoviral vector is used to deliver a cassette of 20 patient-specific TSNA derived from the patient’s own tumor; and second, the same personalized TSNA cassette is delivered using a self-amplifying RNA vector in a repeated boost sequence. GRANITE is being evaluated in combination with immune checkpoint blockade in a Phase 1/2 clinical study, referred to as GO-004. GRANITE was granted Fast Track designation by the U.S. Food and Drug Administration for the treatment of MSS CRC. Is New 90 Day High Low • Sep 25
