CAPTURE: Cancer and COVID-19 antiviral immune monitoring study
2020
Introduction: Certain retrospective and registry-based studies have indicated a higher risk of COVID-19 adverseoutcomes in cancer, but a detailed understanding of the immune response in cancer patients and the impact ofcancer therapy is needed CAPTURE is a pan-cancer, prospective longitudinal study established in response to theunique challenges of SARS-CoV-2 pandemic for the care of cancer patients Experimental Procedures: CAPTURE is a multicenter, UK-based longitudinal cohort study that commencedrecruitment in May 2020 Study participants are recruited from a broad range of cancer types and cancerinterventions and irrespective of their SARS-CoV-2 status, in order to capture both the nominator and thedenominator In addition to cancer patients, the study participants also include health care workers (HCW) for thepurpose of studying transmission dynamics Detailed clinical, epidemiologic, and demographic data are collectedfrom all participants alongside a range of biologic samples that underpin case definitions and will facilitate immunemonitoring All participants will be followed up longitudinally for up to five years Results: The overarching aim is to establish a prospective and unbiased understanding of the susceptibility andmorbidity of COVID-19 in cancer patients and the patterns of viral nosocomial transmission We will follow uppatients long-term to understand the extent and duration of immunity and how immunity is impacted by cancer type, stage, and therapy Our comprehensive sampling will help to draw a detailed picture of immune response to SARS-CoV-2 in cancer patients by monitoring active infection, antibody response, and T-cell activation, supplemented bydetailed immunophenotyping, transcriptome, TCR/BCR sequencing, and germline profiling for HLA typing andidentification of disease-associated polymorphisms Finally, while there is a well-established correlation of circulatingcytokine levels and Covid-19 severity, CAPTURE will identify early indicators of a maladapted inflammatoryresponse in cancer patients by cytokine and chemokine profiling to establish early biomarkers of disease severity Within the first month, we have recruited 95 participants (54% cancer patients, 46% HCWs) with matching swabs, plasma, PBMC, and whole blood for RNA sequencing Two longitudinal samples were collected on average Resultsfrom antigen and antibody profiling within this cohort will be presented at the meeting Conclusion: CAPTURE will provide a detailed understanding of the interaction between immune response toSARS-CoV-2, cancer, and cancer treatments Results will be informative in a wider health care context in order tominimize harm and maximize cancer outcomes in a sustainable manner Furthermore, given inherent and iatrogenicdefects in discreet immune cell subsets, this is a key patient cohort to inform a wider understanding of the immuneresponse to SARS-CoV-2
