Market Data and Key Metrics Changes - The company is focusing on expanding immunotherapy benefits to patients with solid tumors, particularly in the underserved colorectal cancer market, which is a leading cause of cancer deaths [110]. - The ongoing collaboration with BARDA for a Phase 2b study in COVID-19 highlights the company's commitment to infectious disease alongside oncology [84][112]. Company Strategy and Development Direction - The company aims to leverage its neoantigen-directed cancer vaccine technology to address the unmet needs in cold tumors, particularly in metastatic colorectal cancer, which has limited treatment options [10][110]. - The strategic focus includes enhancing partnerships and collaborations to support both oncology and infectious disease programs, with an emphasis on non-dilutive funding sources [86][112]. Management's Comments on Operating Environment and Future Outlook - Management expressed optimism about the upcoming mature PFS data expected in Q3 2024, which could provide significant insights into the efficacy of the GRANITE program [89][107]. - The company is preparing for an end-of-Phase 2 meeting with the FDA to discuss Phase 3 trial designs and endpoints, indicating a proactive approach to regulatory engagement [130][110].

Question: How will ctDNA be used as a biomarker in future studies? - The company plans to explore ctDNA as a surrogate for clinical endpoints, with ongoing analyses to refine its predictive capabilities [127][43]. Question: Will the company continue to stratify by ctDNA in Phase 3? - The intention is to treat all patients without stratification once mature data is available, focusing on the overall efficacy of the product [157][159].
