Abstract Background: ICI are widely used in the treatment of various cancer types. It has been hypothesized that ICI could confer an increased risk of severe acute lung injury or other complications associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: We analyzed data from 113 patients with laboratory-confirmed COVID-19 while on treatment with ICI without chemotherapy in 19 hospitals in North America, Europe, and Australia. Data collected included details on symptoms, comorbidities, medications, treatments and investigations for COVID-19, and outcomes (hospital admission, ICU admission, and mortality). Results: The median age was 63 years (range 27–86); 40 (35%) patients were female. Most common malignancies were melanoma (n=64, 57%), non-small cell lung cancer (n=19, 17%), and renal cell carcinoma (n=11, 10%); 30 (27%) patients were treated for early (neoadjuvant/adjuvant) and 83 (73%) for advanced cancer. Most patients received anti-PD-1 (n=85, 75%), combination anti-PD-1 and anti-CTLA-4 (n=15, 13%), or anti-PD-L1 (n=8, 7%) ICI. Comorbidities included cardiovascular disease (n=31, 27%), diabetes (n=17, 15%), and pulmonary disease (n=14, 12%). Symptoms were present in 68 (60%) patients; 46 (68%) had fever, 40 (59%) cough, and 23 (34%) dyspnea. Overall, ICI was interrupted in 58 (51%) patients. At data cutoff, 33 (29%) patients were admitted to hospital, 6 (5%) to ICU, and 9 (8%) patients died. COVID-19 was the primary cause of death in 7 patients, 3 of whom were admitted to ICU. Cancer types in patients who died were melanoma (2), non-small cell lung cancer (2), renal cell carcinoma (2), and others (3); all (9) patients had advanced cancer. Administered treatments were oxygen therapy (8), mechanical ventilation (2), vasopression (2), antibiotics (7), antiviral drugs (4), glucocorticoids (2), and anti-IL-6 (2). Of all hospitalized patients, 20 (61%) had been discharged and 4 (12%) were still in hospital at data cutoff. Conclusion: The mortality rate of COVID-19 in patients on ICI is higher than rates reported for the general population without comorbidities but may not be higher than rates reported for the cancer population. Despite these preliminary findings, COVID-19 patients on ICI may not have symptoms and a proportion may continue ICI. Correlative analyses are ongoing and will be presented.
