Abstract Background There is no strong evidence that any drug is beneficial either for the treatment of SARS-CoV-2 disease or for post-exposure prophylaxis. Therefore, clinical research is crucial to generate results and evaluate strategies against COVID-19. Primary care (PC) centers, the first level of care in the health system, are in a favorable position to carry out clinical trials (CD), as they work with a large volume of patients with varied profiles (from acute to chronic pathologies). During the COVID-19 pandemic, the need for hospital admission and mortality is higher in people > 60 years. Therefore, this is a target population to try to reduce the serious complications and lethality of COVID pneumonia and to avoid overloading the hospital system. Given the pharmacological properties of colchicine (anti-inflammatory and anti-fibrotic, possible inhibition of viral replication, and inhibitory effect on coagulation activation), early treatment with colchicine may reduce the rate of death and serious pulmonary complications from COVID-19 in vulnerable patients. Methods The COLCHICOVID study is a randomized, multicenter, controlled, open-label parallel group (2:1 ratio), phase III clinical trial to investigate the efficacy of early administration of colchicine in reducing the development of severe pulmonary complications associated with COVID-19 infection in patients over 60 years of age with at-risk comorbidities. Discussion This is a pragmatic clinical trial, adapted to usual clinical practice. The demonstration that early administration of colchicine has clinical effectiveness in reducing the complications of SARS-CoV-2 infection in a population highly susceptible may mitigate the health crisis and prevent the collapse of the health system in the successive waves of the coronavirus pandemic. In addition, colchicine is a well-known medicine, simple to use in the primary care setting and with a low cost for the health system. Trial registration ClinicalTrials.govNCT04416334.

11523 Background: Ewing 2008R1 (EudraCT2008-003658-13, Sponsor UKM) was conducted in 12 countries. It evaluated the effect of zolendronic acid (ZOL) maintenance therapy on event-free (EFS, primary endpoint) and overall survival (OS) from randomization in standard risk Ewing Sarcoma (EwS). Methods: Phase III, open label, prospective, multi-center, randomized controlled clinical trial. Eligible patients (pts) had localized EwS with either good histological response to induction chemotherapy and/or small tumors ( < 200ml). Pts received 6 cycles VIDE induction and 8 VAI (male) or 8 VAC consolidation (female) and were randomized to receive either 9 cycles of maintenance ZOL or no further treatment (control;ctrl). ZOL cycles started parallel to the 6th consolidation cycle. Randomization was stratified by tumor site (pelvis/no pelvis). Two-sided adaptive inverse-normal 4-stage design, changed after the 1st interim analysis via Müller-Schäfer method. Initial sample size 448 pts, type I error rate 5%, power 80%. Results: 284 pts were randomized between 2009 and 2018 (142 ZOL / 142 ctrl). With a median follow-up of 3.9 years, the primary endpoint EFS was not significantly different between the ZOL and ctrl group in the adaptive design (HR 0.74, 95% CI 0.43-1.28, intention to treat). 3-year (3y) EFS rates were 84.0% (95% CI 77.7-90.8%) for ZOL vs 81.7% (95% CI 75.2-88.8%) for ctrl. Results were similar in the per protocol collective. Cause-specific HR for local recurrence in ZOL was csHR 0.30 (95% CI 0.08 -1.09; p = 0.07), for metastatic progress/new metastases csHR 1.0 (CI 0.5-2.2), for combined relapse/progress csHR 0.3 (95% CI 0.1-1.7), for second malignancies csHR 4.0 (95% CI 0.45-36.1) compared to ctrl. The 3y OS was 92.8% (95% CI 88.4-97.5%) for ZOL and 94.6% (95% CI 90.9-98.6%) for ctrl. For ZOL the 5y OS was 87.3% (95% CI 80.7-94.5%) and 89% (95% CI 83.7-95.9%) for ctrl. Noticeable more renal, neurological and gut toxicities were observed for ZOL (p < 0.05), with severe renal toxicities occurring more often in the ZOL arm (p = 0.003). Conclusions: In patients with standard risk localized Ewing Sarcoma there is no benefit from maintenance treatment with zoledronic acid, but significant side effects were observed.

527 Background: Microvascular invasion (MVI) is a risk factor for recurrence after hepatectomy for hepatocellular carcinoma (HCC) patients. This study aimed to investigate to efficacy and safety of postoperative adjuvant transarterial infusion chemotherapy (TAI) with FOLFOX regimen for HCC patients with MVI. Methods: In this prospective, phase III, randomized, open-labeled, controlled clinical trial, HCC patients with histologically confirmed MVI were randomly assigned (1:1) after hepatectomy to receive either 1-2 cycles adjuvant TAI (AT group) or follow-up without any adjuvant treatment (FU group). The primary endpoint was disease-free survival (DFS), the secondary endpoints are overall survival (OS) and safety. Results: Between June, 2016 and April 2019, 127 patients were randomly assigned to AT group (n=63) or FU group (n=64). Clinicopathological characteristics were balanced between the two groups. The 6-, 12-, and 18-month OS rates for AT group were 100.0%, 97.7%, and 97.7%, and were 94.5%, 89.6%, and 78.5% for FU group, respectively. The 6-, 12-, and 18-month DFS rates for AT group were 84.7%, 61.8%, and 58.7%, and were 62.9%, 48.1%, and 38.6% for FU group, respectively. The OS and DFS were significantly better in AT group than in FU group (p=0.037 and 0.023, respectively). No patients in AT group experienced grade 3 or more severe adverse events (AEs). Conclusions: Adjuvant TAI after hepatectomy may bring survival benefits of OS and DFS for HCC patients with MVI. Clinical trial information: NCT03192618.
