ABSTRACT
Background: L is a novel anticancer agent that inhibits trans-activated transcription and modulates the tumor microenvironment. L is approved by the FDA for metastatic SCLC patients (pts) with progressive disease (PD) on or after platinum-based chemotherapy (CT). The LUPER study is assessing the safety, tolerability, and preliminary efficacy of L+P as second-line regimen for SCLC pts after failure of platinum- based CT. Phase 1 data are presented here. Methods: In this phase 1/2 trial (NCT04358237), adult pts with histologically confirmed SCLC, PD to a previous CT-containing regimen (≥4 weeks before study initiation), no prior exposure to immunotherapy, ECOG PS of 0-1, and measurable disease as per RECIST 1.1 are eligible. Pts with treated, stable, and asymptomatic brain metastases (BMs) are allowed. A 3+3 dose-escalation was done to determine the recommended phase 2 dose (RP2D) of L+P. L was dosed at 2.4 mg/m2 and 3.2 mg/m2 IV Q3W in the dose level (DL)1 and 2, respectively, in combination with fixed dose of P (200 mg IV Q3W). The RP2D was the highest DL at which 0/3 pts or ≤1/6 pts experienced dose-limiting toxicities (DLTs) during the first cycle. Treatment was administered until PD, unacceptable toxicity, or consent withdrawal. Secondary endpoints include safety as per CTCAE 5.0, preliminary efficacy, and pharmacokinetics. Results: Thirteen pts were enrolled across 3 hospitals in Spain (DL1, n = 7;DL2, n = 6). Median age was 66 (range 43-78) years, 46.2% were female, 61.5% had ECOG PS of 1, 38.5% had platinum-free interval < 90 days, 30.8% had LDH > upper normal limit, and 15.4% had BMs. One DLT (G3 asthenia) and one G4 neutropenia lasting > 3 days (controlled with G-CSF prophylaxis upon C2, without requiring dose delay or modification) occurred in the DL1. No DLT were reported in the DL2. The RP2D was identified as 3.2 mg/m2 L and 200 mg P IV Q3W. At data cutoff (Jan 21, 2022), 5 (38.4%) pts remained on treatment (1 pt in DL1 discontinued due to COVID-19 in cycle 1). Median duration of treatment was 2.1 (0-11.8) months, 5 (38.5%) pts had ≥8 cycles, and median relative dose intensity of L and P were 91.1% and 95.7%, respectively. Immune-related AEs (G2 pneumonitis;G3 ALT increased) led to P discontinuation in 2 (15.4%) pts. Responses were shown in both DLs, with ORR of 30.8% (1 confirmed complete response and 3 partial responses);3 pts had stable disease (SD;including 1 patient with SD > 12 weeks) and 5 (38.5%) pts experienced PD. Conclusions: This is the first report to demonstrate a manageable safety profile and preliminary efficacy of second-line L+P for relapsed SCLC pts. This combination warrants further confirmation in the ongoing expansion phase 2.
ABSTRACT
Introducción Nos proponemos analizar las complicaciones neurológicas de los pacientes con infección grave por SARS-CoV-2 que han requerido ingreso en unidad de cuidados intensivos (UCI). Pacientes y métodos Estudio descriptivo retrospectivo, observacional, de pacientes consecutivos ingresados en UCI por infección respiratoria grave por SARS-CoV-2 desde el 1 de abril hasta el 1 de junio de 2020. Resultados Registramos 30 pacientes con síntomas neurológicos, 21 hombres (72,40%), edad media: 57,41 años ± 11,61 desviación estándar (DE). Estancia media en UCI: 18,83 ± 14,33 DE. A nivel sindrómico: 28 pacientes (93,33%) con síndrome confusional agudo, 15 (50%) con patología neuromuscular, 5 (16,66%) con cefalea, 4 (13,33%) con patología cerebrovascular y 4 (13,33%) con encefalopatías/encefalitis. Punción lumbar normal en 6 pacientes (20%). La RMN craneal o TAC craneal mostró alteraciones en 20 casos (66,6%). Se realizó EEG en todos los pacientes (100%), alterado en 8 pacientes (26,66%). En 5 de los 15 pacientes con miopatía clínica se ha podido confirmar con ENMG. Hemos encontrado relación entre la mayor edad y los días de ingreso en UCI (p = 0,002;IC 95%: 4,032-6,022;OR: 3,594). Conclusiones La infección grave por COVID-19 afecta mayoritariamente a hombres, similar a lo descrito en otras series. La mitad de nuestros pacientes presenta una miopatía aguda, y casi la totalidad de los pacientes salen de la UCI con síndromes confusionales agudos que evolucionan a una resolución completa, sin correlacionarse con los resultados del EEG o de pruebas de neuroimagen. La mayor edad se asocia con un mayor número de días de estancia en UCI.
ABSTRACT
Introduction/Background: COVID-19 is the disease caused by SARSCov2. Various prognostic factors have been studied and described. Atrial fibrillation (AF) is an arrhythmia associated with increased complications and mortality in acute situations. The onset of AF in patients hospitalized for COVID-19 could associate a worse prognosis during admission and in the short term. Purpose: The objective of this study is to evaluate the adverse events in the population admitted for COVID-19 that develops AF as well as its possible prognostic value. Methods: Retrospective, cohort study on 391 patients admitted for COVID- 19 in a tertiary hospital. Descriptive and comparative analysis between those with new onset AF versus those who had AF previously in terms of: baseline characteristics, In hospital mortality, bleeding and thrombotic phenomena. Follow-up during three months after discharge. Univariate and multivariate analysis of in-hospital and three-months mortality is also performed. Results: 391 patients were included. 21 of them developed AF. These patients are older, more hypertensive and with more history of cardiopathy. At admission, they presented higher mortality (52.4% vs 19.7%;p<0.001) and bleeding (19% vs 8.4%;p<0.001), also compared to those with previous AF (not significant). New onset AF is not an independent predictor of in-hospital mortality, but rather an independent predictor of three-month mortality. In-hospital mortality predictors are: age >70 years, BCRSS scale >2 points, and severe hypotension. Three-month mortality predictors are: high-sensitive T-troponin <50ng/dl, age >70 years, BCRSS scale >2, creatinine >1.5 mg/dl and new-onset AF. Conclusions: New onset AF appears in 5,3% of these hospitalized patients, who have greater comorbidity, bleeding and in-hospital mortality as well as three-months mortality. New onset AF is not an independent predictor of in-hospital mortality but rather an independent predictor of mortality during the first three months after discharge (Figure Presented).
ABSTRACT
INTRODUCTION: We analysed the neurological complications of patients with severe SARS-CoV-2 infection who required intensive care unit (ICU) admission. PATIENTS AND METHODS: We conducted a retrospective, observational, descriptive study of consecutive patients admitted to the ICU due to severe respiratory symptoms secondary to SARS-CoV-2 infection between 1 April and 1 June 2020. RESULTS: We included 30 patients with neurological symptoms; 21 were men (72.40%), and mean age (standard deviation [SD]) was 57.41 years (11.61). The mean duration of ICU stay was 18.83 days (14.33). The neurological conditions recorded were acute confusional syndrome in 28 patients (93.33%), neuromuscular disease in 15 (50%), headache in 5 (16.66%), cerebrovascular disease in 4 (13.33%), and encephalopathies/encephalitis in 4 (13.33%). CSF analysis results were normal in 6 patients (20%). Brain MRI or head CT showed alterations in 20 patients (66.6%). EEG was performed in all patients (100%), with 8 (26.66%) showing abnormal findings. In 5 of the 15 patients with clinical myopathy, diagnosis was confirmed with electroneuromyography. We found a correlation between older age and duration of ICU stay (P=.002; 95%CI: 4.032-6.022; OR: 3,594). CONCLUSIONS: Severe COVID-19 mainly affects men, as observed in other series. Half of our patients presented acute myopathy, and almost all patients left the ICU with acute confusional syndrome, which fully resolved; no correlation was found with EEG or neuroimaging findings. Older age is associated with longer ICU stay.
