135 Background: Black patients have a disproportionately high incidence and mortality from lung cancer. Despite the importance of clinical trials, there continue to be significant racial disparities in recruitment for pivotal registration studies. In 2016, the FDA recommended reporting racial enrollment with a minimum of 5 categories (White, Black, Asian, American Indian or Alaskan Native [AIAN] and Native Hawaiian or Pacific Islander [NHPI]). The International Committee of Medical Journal Editors also recommend reporting race and ethnicity. We evaluated race reporting and representation in registration trials for thoracic cancers. Methods: We reviewed the FDA website and identified all new drug licensing indications in thoracic malignancies (small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC) and mesothelioma) from 2006 to 2020. NSCLC was further classified as EGFR+, ALK+, other mutation and NOS (no driver mutation). Clinical trials cited on the licensing label for market authorization were recorded and the corresponding registration trial publication was identified. If race was unreported or underreported (defined as ≤3 groups) in the licensing study, then additional information was obtained from clinicaltrials.gov. We calculated the proportion of registration trials meeting FDA criteria and the proportion of each racial group in trials. Results: From 2006-2020, we identified 55 new licensing indications, involving 26 unique drugs; 5 approvals in SCLC, 49 approvals in NSCLC and 1 in mesothelioma. Prior to the FDA race reporting guidelines, 33% (6/18) of registration studies did not meet FDA requirements. This improved to 27% (10/37) after the guideline introduction. Overall 29,545 patients participated in thoracic registration trials; 66% White, 22% Asian, 2% Black, <1% AIAN, <1% NHPI, 1% other or multiple races and 9% unknown. Table shows race distribution by cancer subtype. Conclusions: Although improving, a substantial number of registrational clinical trials in thoracic oncology still do not report race per FDA guidance. In addition, Black individuals are disproportionately under-represented in registration trials. Greater efforts are needed for the inclusion of Black patients and other minorities in clinical trials.[Table: see text]

11523 Background: Sarcoma pts often receive aggressive, highly immunosuppressive therapy and may be at high risk for severe COVID-19. Demographics, outcomes and risk factors for pts with sarcoma and COVID-19 are unknown. We aimed to describe the course of COVID-19 in sarcoma pts and to identify factors associated with adverse outcomes. Methods: The COVID-19 and Cancer Consortium (NCT04354701) is an international registry of pts with cancer and COVID-19. Adult pts (≥18 years old) with a diagnosis of sarcoma and laboratory confirmed SARS-CoV-2 were included from 50 participating institutions. Data including demographics, sarcoma diagnosis and treatment, and course of COVID-19 infection were analyzed. Primary outcome was the composite rate of hospitalization or death at 30 days from COVID-19 diagnosis. Secondary outcomes were 30 day all-cause mortality, rate of hospitalization, O2 need, and ICU admission. Descriptive statistics and univariate Fisher tests are reported. Results: From March 17, 2020 to February 6, 2021, N=204 pts were included. Median follow up was 42 days. Median age was 58 years (IQR 43-67). 97 (48%) were male. 30 (15%) had ECOG performance status ≥2. 104 (51%) received cancer treatment, including surgery or radiation, within 3 months of COVID-19 diagnosis. 153 (75%) had active cancer, of whom 34 (22%) had lung metastases. 100 (49%) pts met the composite primary endpoint; 96 (47%) were hospitalized and 18 (9%) died within 30 days from COVID-19 diagnosis. 64 (31%) required oxygen, and 16 (8%) required ICU admission. Primary endpoint rates were similar for pts who received cytotoxic chemotherapy (38/58, 66%) or targeted therapy (16/28, 57%). Pts with higher rates of the primary endpoint included patients ≥60 years old (59% vs 40%, OR 2.04, 95% CI 1.12-3.74, p=0.016), pts with ECOG PS ≥2 vs 0-1 (90% vs 41%, OR 12.2, 95% CI 3.44-66.8, p<0.001), pts receiving any systemic therapy within 3 months of COVID-19 diagnosis (62% vs 39%, OR 2.65, 95% CI 1.43-4.97, p=0.001), and pts with lung metastases (68% vs 42%, OR 2.77, 95% CI 1.19-6.79, p=0.013). Primary endpoint rates were similar across sarcoma subtypes (Table). Conclusions: This is the largest cohort study of pts with sarcoma and COVID-19 to date. Sarcoma pts have high rates of complications from COVID-19. Older patients, those with poor performance status, those recently receiving systemic cancer therapy, and those with lung metastases appear to have worse outcomes.[Table: see text]

Abstract Background: Overall, patients with cancer experience a greater risk of adverse outcomes following SARS-CoV-2 infection; however, little is known for those with BC. Methods: CCC19 (NCT04354701) is an international cohort study aimed at investigating the impact of COVID-19 in patients with a history of or active cancer using de-identified data on patient demographics, cancer history, clinical course and outcomes of COVID-19. The current analysis includes patients from U.S. and Canada with invasive BC and laboratory-confirmed SARS-CoV-2 entered between March 17, 2020 and July 2, 2020. Co-primary outcomes were hospitalization during COVID-19 illness and 30-day all-cause mortality. Frequencies for categorical variables and medians (range) for continuous variables were estimated. Final presentation will include bivariable and multivariable Cox proportional hazards regression analysis to identify risk factors (including BC subtypes and therapies, for which data collection is ongoing) associated with 30-day all-cause mortality and severe COVID-19 illness (composite of any hospitalization requiring supplemental oxygen, admission to an intensive care unit [ICU], use of mechanical ventilation, or death). Results: During the study period, a total of 2683 patients with cancer and COVID-19 were accrued in the CCC19 registry including 529 (20%) with invasive BC. Among patients with BC, 352 (67%) were 60 years or older; 518 (98%) were women; 275 (52%) non-Hispanic White, 116 (22%) non-Hispanic Black, 70 (13%) Hispanic, 56 (11%) in other categorizations; 178 (34%) had a smoking history; 75 (14%) ECOG performance status ≥2; 191 (36%) with &gt;2 active comorbidities; 64 (12%) with AJCC stage IV disease at BC diagnosis; and 267 (50%) were on anti-cancer treatment including systemic therapy, radiation, or surgery within 3 months of COVID-19 diagnosis. At least 323 (61%) patients with BC had 30-day follow-up after COVID-19 diagnosis, and 35 (7%) had 90-day follow-up. COVID-19 illness at initial diagnosis required outpatient care in 288 (54%), inpatient care in 193 (36%), and ICU care in 40 (8%). Overall, 247 (47%) were hospitalized and 30-day all-cause mortality was 9%. 30-day all-cause mortality rates by receipt of major BC treatment modalities (within past 3 months) were: 10% for those on cytotoxic systemic therapy vs 5% and 12% for noncytotoxic systemic therapy and local therapy, respectively. The table shows hospitalization and mortality outcomes by major demographic and BC treatment strata. The final presentation will incorporate the latest patient accrual and evaluate independent clinical risk factors associated with serious COVID-19 outcomes in patients with BC. Conclusions: This represents the largest study to date of COVID-19 outcomes in patients with invasive BC. Nearly half of the patients with BC required hospitalization during their COVID-19 disease course and we observed a 9% 30-day all-cause mortality.

Abstract Among 2,186 U.S. adults with invasive cancer and laboratory-confirmed SARS-CoV-2 infection, we examined the association of COVID-19 treatments with 30-day all-cause mortality and factors associated with treatment. Logistic regression with multiple adjustments (e.g., comorbidities, cancer status, baseline COVID-19 severity) was performed. Hydroxychloroquine with any other drug was associated with increased mortality versus treatment with any COVID-19 treatment other than hydroxychloroquine or untreated controls; this association was not present with hydroxychloroquine alone. Remdesivir had numerically reduced mortality versus untreated controls that did not reach statistical significance. Baseline COVID-19 severity was strongly associated with receipt of any treatment. Black patients were approximately half as likely to receive remdesivir as white patients. Although observational studies can be limited by potential unmeasured confounding, our findings add to the emerging understanding of patterns of care for patients with cancer and COVID-19 and support evaluation of emerging treatments through inclusive prospective controlled trials. Significance: Evaluating the potential role of COVID-19 treatments in patients with cancer in a large observational study, there was no statistically significant 30-day all-cause mortality benefit with hydroxychloroquine or high-dose corticosteroids alone or in combination; remdesivir showed potential benefit. Treatment receipt reflects clinical decision-making and suggests disparities in medication access. This article is highlighted in the In This Issue feature, p. 1426
