研究概览
简要总结
The goal of this single center, double-blinded, placebo-controlled, and randomized Phase 1 trial is to determine if i.v. citicoline is safe and efficacious compared to i.v. saline/control in adults presenting with SARS CoV-2 infection complicated by acute hypoxemic respiratory failure. The main questions it aims to answer:
- Is citicoline safe in this patient population?
- Does citicoline have a benefit in terms of improving oxygenation?
- Does citicoline reduce overall severity of illness as reflected by standardized scales.
Patients will be assigned to i.v. treatment with citicoline or saline twice daily for 5 consecutive days. SpO2/FiO2 ratios will be recorded daily as per standard clinical practice to compare citicoline treatments at three different doses to placebo.
详细描述
SCARLET is a single center, double-blinded, placebo-controlled, and randomized Phase 1 trial of i.v. citicoline in adult patients of any sex, gender, age, or ethnicity who are present with acute hypoxemic respiratory failure due to SARS CoV-2 infection. The goals are safety over a range of doses based on the number of treatment related adverse events as assessed by CTCAE v.5, and demonstration of efficacy as reflected by SpO2/FiO2 measured at day 3 in hospitalized COVID infected patients with acute hypoxemic respiratory failure, as defined by requiring at least 4 liters nasal cannula oxygen supplementation to maintain the SpO2 above 90%. The trial will enroll 20 patients per dose for 3 citicoline doses (1, 5, and 10 mg/kg/day) along with 20 placebo-treated controls.

结局指标
主要结局
Safety of citicoline over a range of doses in COVID-19 patients presenting with acute hypoxemic respiratory failure.
时间窗: Until hospital discharge or up to 29 days
Safety will be assessed in each arm of the study: 1, 5, or 10 mg/kg/day citicoline by i.v. bolus or i.v. saline bolus for 5 consecutive days. Safety analysis will be performed based on a continuous safety monitoring rule to guide accrual suspension decisions based on number of treatment-related adverse events as assessed by the CTCAE v.5.0. The number of patients with an SAE that would warrant temporary suspension of accrual in a given group corresponds to a high posterior probability that the true SAE probability is greater than an acceptable level (i.e., Pr(pi \> 0.25 \| data) \> 0.85), where the posterior probability is determined from a Beta-Binomial distribution with Beta (1, 1) as the prior on pi.
Citicoline's effect on acute hypoxemic respiratory failure in COVID-19 patients.
时间窗: Day 3
The primary clinical outcome will be measured on Day 3: lowest recorded SpO2/FiO2 ratio.
次要结局
- Effect of citicoline on COVID specific disease severity scale in patients with acute COVID associated hypoxemic respiratory failure.(Through day 8)
- Effect of citicoline on Sequential Organ Failure Score (SOFA) in patients with COVID associated acute respiratory failure.(Through day 8)
