The aim of this single-arm, phase II study was to estimate the tumor response rate and safety profile of erlotinib HCl (erlotinib, Tarceva, OSI-774) monotherapy in patients with refractory, recurrent, HER1/EGFR-positive epithelial ovarian tumors, who had failed prior taxane and/or platinum-based chemotherapy. Thirty-four patients received 150 mg erlotinib orally once daily for up to 48 weeks or until disease progression or dose-limiting toxicity. Two patients had partial responses, lasting 8+ and 17 weeks, giving an objective response rate of 6% (95% confidence interval [CI], 0.7-19.7%). Fifteen patients (44%) had stable disease, and 17 patients (50%) had progressive disease. Median overall survival was 8 months (95% CI, 5.7-12.7 months), with a 1-year survival rate of 35.3% (95% CI, 19.8-53.5%). Patients with rash survived significantly longer than those without (P= 0.009), correlating with rash grade. Erlotinib was generally well tolerated. The most frequent erlotinib-related adverse events were rash (68%) and diarrhea (38%). Erlotinib had marginal activity but was generally well tolerated. The safety profile appears more favorable than typically experienced with standard chemotherapeutic agents, which is encouraging in these heavily pretreated patients. Combination of erlotinib with chemotherapy or other targeted agents should be considered.

Background Observational studies have consistently described poor clinical outcomes and increased ICU mortality in patients with severe coronavirus disease 2019 (COVID-19) who require mechanical ventilation (MV). Our study describes the clinical characteristics and outcomes of patients with severe COVID-19 admitted to ICU in the largest health care system in the state of Florida, United States. Methods Retrospective cohort study of patients admitted to ICU due to severe COVID-19 in AdventHealth health system in Orlando, Florida from March 11th until May 18th, 2020. Patients were characterized based on demographics, baseline comorbidities, severity of illness, medical management including experimental therapies, laboratory markers and ventilator parameters. Major clinical outcomes analyzed at the end of the study period were: hospital and ICU length of stay, MV-related mortality and overall hospital mortality of ICU patients. Results Out of total of 1283 patients with COVID-19, 131 (10.2%) met criteria for ICU admission (median age: 61 years [interquartile range (IQR), 49.5–71.5]; 35.1% female). Common comorbidities were hypertension (84; 64.1%), and diabetes (54; 41.2%). Of the 131 ICU patients, 109 (83.2%) required MV and 9 (6.9%) received ECMO. Lower positive end expiratory pressure (PEEP) were observed in survivors [9.2 (7.7–10.4)] vs non-survivors [10 (9.1–12.9] p = 0.004]. Compared to non-survivors, survivors had a longer MV length of stay (LOS) [14 (IQR 8–22) vs 8.5 (IQR 5–10.8) p< 0.001], Hospital LOS [21 (IQR 13–31) vs 10 (7–1) p< 0.001] and ICU LOS [14 (IQR 7–24) vs 9.5 (IQR 6–11), p < 0.001]. The overall hospital mortality and MV-related mortality were 19.8% and 23.8% respectively. After exclusion of hospitalized patients, the hospital and MV-related mortality rates were 21.6% and 26.5% respectively. Conclusions Our study demonstrates an important improvement in mortality of patients with severe COVID-19 who required ICU admission and MV in comparison to previous observational reports and emphasizes the importance of standard of care measures in the management of COVID-19.

Consolidation therapy with oregovomab did not significantly improve TTR overall. A set of confirmatory phase III studies has been initiated to determine whether the SFLT population derives benefit from oregovomab treatment.
