ABSTRACT

Nezulcitinib (TD-0903), a lung-selective pan-Janus-associated kinase (JAK) inhibitor designed for inhaled delivery, is under development for treatment of acute lung injury associated with coronavirus disease 2019 (COVID-19). This two-part, double-blind, randomized, placebo-controlled, single ascending dose (part A) and multiple ascending dose (part B) phase I study evaluated the safety, tolerability, and pharmacokinetics (PK) of nezulcitinib in healthy participants. Part A included three cohorts randomized 6:2 to receive a single inhaled dose of nezulcitinib (1, 3, or 10 mg) or matching placebo. Part B included three cohorts randomized 8:2 to receive inhaled nezulcitinib (1, 3, or 10 mg) or matching placebo for 7 days. The primary outcome was nezulcitinib safety and tolerability assessed from treatment-emergent adverse events (TEAEs). The secondary outcome was nezulcitinib PK. All participants completed the study. All TEAEs were mild or moderate in severity, and none led to treatment discontinuation. Overall (area under the plasma concentration-time curve) and peak (maximal plasma concentration) plasma exposures of nezulcitinib were low and increased in a dose-proportional manner from 1 to 10 mg in both parts, with no suggestion of clinically meaningful drug accumulation. Maximal plasma exposures were below levels expected to result in systemic target engagement, consistent with a lung-selective profile. No reductions in natural killer cell counts were observed, consistent with the lack of a systemic pharmacological effect and the observed PK. In summary, single and multiple doses of inhaled nezulcitinib at 1, 3, and 10 mg were well-tolerated in healthy participants, with dose-proportional PK supporting once-daily administration.

ABSTRACT

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved into an emergent global pandemic. Coronavirus disease 2019 (COVID-19) can manifest on a spectrum of illness from mild disease to severe respiratory failure requiring intensive care unit admission. As the incidence continues to rise at a rapid pace, critical care teams are faced with challenging treatment decisions. There is currently no widely accepted standard of care in the pharmacologic management of patients with COVID-19. Urgent identification of potential treatment strategies is a priority. Therapies include novel agents available in clinical trials or through compassionate use, and other drugs, repurposed antiviral and immunomodulating therapies. Many have demonstrated in vitro or in vivo potential against other viruses that are similar to SARS-CoV-2. Critically ill patients with COVID-19 have additional considerations related to adjustments for organ impairment and renal replacement therapies, complex lists of concurrent medications, limitations with drug administration and compatibility, and unique toxicities that should be evaluated when utilizing these therapies. The purpose of this review is to summarize practical considerations for pharmacotherapy in patients with COVID-19, with the intent of serving as a resource for health care providers at the forefront of clinical care during this pandemic.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread worldwide and is also an important disease in Japan. Thus, the optimal treatment strategy for severe COVID-19 should be established urgently. The effects of combination treatment with baricitinib-a Janus kinase inhibitor, remdesivir, and dexamethasone (BRD) are unknown. METHODS: Patients who received combination therapy with BRD at the Japanese Red Cross Medical Center were enrolled in the study. All patients received baricitinib (≤14 d), remdesivir (≤10 d), and dexamethasone (≤10 d). The efficacy and adverse events were evaluated. RESULTS: In total, 44 patients with severe COVID-19 were enrolled in this study. The 28-d mortality rate was low at 2.3% (1/44 patients). The need for invasive mechanical ventilation was avoided in most patients (90%, 17/19 patients). Patients who received BRD therapy had a median hospitalization duration of 11 d, time to recovery of 9 d, duration of intensive care unit stay of 6 d, duration of invasive mechanical ventilation of 5 d, and duration of supplemental oxygen therapy of 5 d. Adverse events occurred in 15 patients (34%). Liver dysfunction, thrombosis, iliopsoas hematoma, renal dysfunction, ventilator-associated pneumonia, infective endocarditis, and herpes zoster occurred in 11%, 11%, 2%, 2%, 2%, 2%, and 2% of patients, respectively. CONCLUSIONS: Combination therapy with BRD was effective in treating severe COVID-19, and the incidence rate of adverse events was low. The results of the present study are encouraging; however, further randomized clinical studies are needed.

ABSTRACT

BACKGROUND: Older adults are at the highest risk of severe disease and death due to COVID-19. Randomized data have shown that baricitinib improves outcomes in these patients, but focused stratified analyses of geriatric cohorts are lacking. Our objective was to analyze the efficacy of baricitinib in older adults with COVID-19 moderate-to-severe pneumonia. METHODS: This is a propensity score [PS]-matched retrospective cohort study. Patients from the COVID-AGE and Alba-Score cohorts, hospitalized for moderate-to-severe COVID-19 pneumonia, were categorized in two age brackets of age <70 years old (86 with baricitinib and 86 PS-matched controls) or ≥70 years old (78 on baricitinib and 78 PS-matched controls). Thirty-day mortality rates were analyzed with Kaplan-Meier and Cox proportional hazard models. RESULTS: Mean age was 79.1 for those ≥70 years and 58.9 for those <70. Exactly 29.6% were female. Treatment with baricitinib resulted in a significant reduction in death from any cause by 48% in patients aged 70 or older, an 18.5% reduction in 30-day absolute mortality risk (n/N: 16/78 [20.5%] baricitinib, 30/78 [38.5%] in PS-matched controls, p < 0.001) and a lower 30-day adjusted fatality rate (HR 0.21; 95% CI 0.09-0.47; p < 0.001). Beneficial effects on mortality were also observed in the age group <70 (8.1% reduction in 30-day absolute mortality risk; HR 0.14; 95% CI 0.03-0.64; p = 0.011). CONCLUSIONS: Baricitinib is associated with an absolute mortality risk reduction of 18.5% in adults older than 70 years hospitalized with COVID-19 pneumonia.

ABSTRACT

OBJECTIVES: Baricitinib is supposed to have a double effect on SARS-CoV2 infection. Firstly, it reduces the inflammatory response through the inhibition of the Januse-Kinase signalling transducer and activator of transcription (JAK-STAT) pathway. Moreover, it reduces the receptor mediated viral endocytosis by AP2-associated protein kinase 1 (AAK1) inhibition. We propose the use of baricinitib to prevent the progression of the respiratory insufficiency in SARS-CoV2 pneumonia in onco-haematological patients. In this phase Ib/II study, the primary objective in the safety cohort is to describe the incidence of severe adverse events associated with baricitinib administration. The primary objective of the randomized phase (baricitinib cohort versus standard of care cohort) is to evaluate the number of patients who did not require mechanical oxygen support since start of therapy until day +14 or discharge (whichever it comes first). The secondary objectives of the study (only randomized phase of the study) are represented by the comparison between the two arms of the study in terms of mortality and toxicity at day+30. Moreover, a description of the immunological related changes between the two arms of the study will be reported. TRIAL DESIGN: The trial is a phase I/II study with a safety run-in cohort (phase 1) followed by an open label phase II randomized controlled trial with an experimental arm compared to a standard of care arm. PARTICIPANTS: The study will be performed at the Institut Català d'Oncologia, a tertiary level oncological referral center in the Catalonia region (Spain). The eligibility criteria are: patients > 18 years affected by oncological diseases; ECOG performance status < 2 (Karnofsky score > 60%); a laboratory confirmed infection with SARS-CoV-2 by means of real -time PCR; radiological signs of low respiratory tract disease; absence of organ dysfunction (a total bilirubin within normal institutional limits, AST/ALT≤2.5 X institutional upper limit of normal, alkaline phosphatase ≤2.5 X institutional upper limit of normal, coagulation within normal institutional limits, creatinine clearance >30 mL/min/1.73 m2 for patients with creatinine levels above institutional normal); absence of HIV infection; no active or latent HBV or HCV infection. The exclusion criteria are: patients with oncological diseases who are not candidates to receive any active oncological treatment; hemodynamic instability at time of study enrollment; impossibility to receive oral medication; medical history of recent or active pulmonary embolism or deep venous thrombosis or patients at high-risk of suffering them (surgical intervention, immobilization); multi organ failure, rapid worsening of respiratory function with requirement of fraction of inspired oxygen (FiO2) > 50% or high-flow nasal cannula before initiation of study treatment; uncontrolled intercurrent illness (ongoing or severe active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements); allergy to one or more of study treatments; pregnant or breastfeeding women; positive pregnancy test in a pre-dose examination. Patients should have the ability to understand, and the willingness to sign, a written informed consent document; the willingness to accept randomization to any assigned treatment arm; and must agree not to enroll in another study of an investigational agent prior to completion of Day +28 of study. An electronic Case Report Form in the Research Electronic Data Capture (REDCap) platform will be used to collect the data of the trial. Removal from the study will apply in case of unacceptable adverse event(s), development of an intercurrent illness, condition or procedural complication, which could interfere with the patient's continued participation and voluntary patient withdrawal from study treatment (all patients are free to withdraw from participation in this study at any time, for any reasons, specified or unspecified, and without prejudice). INTERVENTION AND COMPARATOR: Treatment will be administered on an inpatient basis. We will compare the experimental treatment with baricitinib plus the institutional standard of care compared with the standard of care alone. During the phase I, we will define the dose-limiting toxicity of baricitinib and the dose to be used in the phase 2 part of the study. The starting baricitinib dose will be an oral tablet 4 mg-once daily which can be reduced to 2 mg depending on the observed toxicity. The minimum duration of therapy will be 5 days and it can be extended to 7 days. The standard of care will include the following therapies. Antibiotics will be individualized based on clinical suspicion, including the management of febrile neutropenia. Prophylaxis of thromboembolic disease will be administered to all participants. Remdesivir administration will be considered only in patients with severe pneumonia (SatO2 <94%) with less than 7 days of onset of symptoms and with supplemental oxygen requirements but not using high-flow nasal cannula, non-invasive or invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO). In the randomized phase, tocilizumab or interferon will not be allowed in the experimental arm. Tocilizumab can be used in patients in the standard of care arm at the discretion of the investigator. If it is prescribed it will be used according to the following criteria: patients who, according to his baseline clinical condition, would be an ICU tributary, interstitial pneumonia with severe respiratory failure, patients who are not on mechanical ventilation or ECMO and who are still progressing with corticoid treatment or if they are not candidates for corticosteroids. Mild ARDS (PAFI <300 mmHg) with radiological or blood gases deterioration that meets at least one of the following criteria: CRP >100mg/L D-Dimer >1,000µg/L LDH >400U/L Ferritin >700ng/ml Interleukin 6 ≥40ng/L. The use of tocilizumab is not recommended if there are AST/ALT values greater than 10 times the upper limit of normal, neutrophils <500 cells/mm3, sepsis due to other pathogens other than SARS-CoV-2, presence of comorbidity that can lead to a poor prognosis, complicated diverticulitis or intestinal perforation, ongoing skin infection. The dose will be that recommended by the Spanish Medicine Agency in patients ≥75Kg: 600mg dose whereas in patients <75kg: 400mg dose. Exceptionally, a second infusion can be assessed 12 hours after the first in those patients who experience a worsening of laboratory parameters after a first favourable response. The use of corticosteroids will be recommended in patients who have had symptoms for more than 7 days and who meet all the following criteria: need for oxygen support, non-invasive or invasive mechanical ventilation, acute respiratory failure or rapid deterioration of gas exchange, appearance or worsening of bilateral alveolar-interstitial infiltrates at the radiological level. In case of indication, it is recommended: dexamethasone 6mg/d p.o. or iv for 10 days or methylprednisolone 32mg/d orally or 30mg iv for 10 days or prednisone 40mg day p.o. for 10 days. MAIN OUTCOMES: Phase 1 part: to describe the toxicity profile of baricitinib in COVID19 oncological patients during the 5-7 day treatment period and until day +14 or discharge (whichever it comes first). Phase 2 part: to describe the number of patients in the experimental arm that will not require mechanical oxygen support compared to the standard of care arm until day +14 or discharge (whichever it comes first). RANDOMISATION: For the phase 2 of the study, the allocation ratio will be 1:1. Randomization process will be carried out electronically through the REDcap platform ( https://www.project-redcap.org/ ) BLINDING (MASKING): This is an open label study. No blinding will be performed. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): The first part of the study (safety run-in cohort) will consist in the enrollment of 6 to 12 patients. In this population, we will test the toxicity of the experimental treatment. An incidence of severe adverse events grade 3-4 (graded by Common Terminology Criteria for Adverse Events v.5.0) inferior than 33% will be considered sufficient to follow with the next part of the study. The second part of the study we will perform an interim analysis of efficacy at first 64 assessed patients and a definitive one will analyze 128 assessed patients. Interim and definitive tests will be performed considering in both cases an alpha error of 0.05. We consider for the control arm this rate is expected to be 0.60 and for the experimental arm of 0.80. Considering this data, a superiority test to prove a difference of 0.20 with an overall alpha error of 0.10 and a beta error of 0.2 will be performed. Considering a 5% of dropout rate, it is expected that a total of 136 patients, 68 for each study arm, will be required to complete study accrual. TRIAL STATUS: Version 5.0. 14th October 2020 Recruitment started on the 16th of December 2020. Expected end of recruitment is June 2021.

ABSTRACT

Importance: Baricitinib, an oral selective Janus kinase 1 and 2 inhibitor, effectively reduced disease severity in moderate to severe atopic dermatitis (AD) in 2 phase 3 monotherapy studies. Objective: To assess the efficacy and safety of 4 mg and 2 mg of baricitinib in combination with background topical corticosteroid (TCS) therapy in adults with moderate to severe AD who previously had an inadequate response to TCS therapy. Design, Setting, and Participants: This double-blind, placebo-controlled, phase 3 randomized clinical trial, BREEZE-AD7 (Study of Baricitinib [LY3009104] in Combination With Topical Corticosteroids in Adults With Moderate to Severe Atopic Dermatitis) was conducted from November 16, 2018, to August 22, 2019, at 68 centers across 10 countries in Asia, Australia, Europe, and South America. Patients 18 years or older with moderate to severe AD and an inadequate response to TCSs were included. After completing the study, patients were followed up for up to 4 weeks or enrolled in a long-term extension study. Interventions: Patients were randomly assigned (1:1:1) to receive 2 mg of baricitinib once daily (n = 109), 4 mg of baricitinib once daily (n = 111), or placebo (n = 109) for 16 weeks. The use of low-to-moderate potency TCSs was allowed. Main Outcomes and Measures: The primary end point was the proportion of patients achieving a validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) score of 0 (clear) or 1 (almost clear), with a 2-point or greater improvement from baseline at week 16. Results: Among 329 patients (mean [SD] age, 33.8 [12.4] years; 216 [66%] male), at week 16, a vIGA-AD score of 0 (clear) or 1 (almost clear) was achieved by 34 patients (31%) receiving 4 mg of baricitinib and 26 (24%) receiving 2 mg of baricitinib compared with 16 (15%) receiving placebo (odds ratio vs placebo, 2.8 [95% CI, 1.4-5.6]; P = .004 for the 4-mg group; 1.9 [95% CI, 0.9-3.9]; P = .08 for the 2-mg group). Treatment-emergent adverse events were reported in 64 of 111 patients (58%) in the 4-mg group, 61 of 109 patients (56%) in the 2-mg group, and 41 of 108 patients (38%) in the placebo group. Serious adverse events were reported in 4 patients (4%) in the 4-mg group, 2 (2%) in the 2-mg group, and 4 (4%) in the placebo group. The most common adverse events were nasopharyngitis, upper respiratory tract infections, and folliculitis. Conclusions and Relevance: A dose of 4 mg of baricitinib in combination with background TCS therapy significantly improved the signs and symptoms of moderate to severe AD, with a safety profile consistent with previous studies of baricitinib in AD.

ABSTRACT

BACKGROUND: Severe coronavirus disease 2019 (Covid-19) is associated with dysregulated inflammation. The effects of combination treatment with baricitinib, a Janus kinase inhibitor, plus remdesivir are not known. METHODS: We conducted a double-blind, randomized, placebo-controlled trial evaluating baricitinib plus remdesivir in hospitalized adults with Covid-19. All the patients received remdesivir (≤10 days) and either baricitinib (≤14 days) or placebo (control). The primary outcome was the time to recovery. The key secondary outcome was clinical status at day 15. RESULTS: A total of 1033 patients underwent randomization (with 515 assigned to combination treatment and 518 to control). Patients receiving baricitinib had a median time to recovery of 7 days (95% confidence interval [CI], 6 to 8), as compared with 8 days (95% CI, 7 to 9) with control (rate ratio for recovery, 1.16; 95% CI, 1.01 to 1.32; P = 0.03), and a 30% higher odds of improvement in clinical status at day 15 (odds ratio, 1.3; 95% CI, 1.0 to 1.6). Patients receiving high-flow oxygen or noninvasive ventilation at enrollment had a time to recovery of 10 days with combination treatment and 18 days with control (rate ratio for recovery, 1.51; 95% CI, 1.10 to 2.08). The 28-day mortality was 5.1% in the combination group and 7.8% in the control group (hazard ratio for death, 0.65; 95% CI, 0.39 to 1.09). Serious adverse events were less frequent in the combination group than in the control group (16.0% vs. 21.0%; difference, -5.0 percentage points; 95% CI, -9.8 to -0.3; P = 0.03), as were new infections (5.9% vs. 11.2%; difference, -5.3 percentage points; 95% CI, -8.7 to -1.9; P = 0.003). CONCLUSIONS: Baricitinib plus remdesivir was superior to remdesivir alone in reducing recovery time and accelerating improvement in clinical status among patients with Covid-19, notably among those receiving high-flow oxygen or noninvasive ventilation. The combination was associated with fewer serious adverse events. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT04401579.).

ABSTRACT

BACKGROUND: Baricitinib is approved for the treatment of rheumatoid arthritis (RA). The authors retrospectively investigated adverse events (AEs) by data-mining a self-reporting database to better understand toxicities, especially since it has been used during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A reporting odds ratio (ROR) was used to detect the risk signals from the data in the US Food and Drug Administration (FDA) adverse event reporting system database (FAERS). The definition relied on system organ class (SOCs) and preferred terms (PTs) by the Medical Dictionary for Regulatory Activities (MedDRA). RESULTS: The search retrieved 1,598 baricitinib-associated cases within the reporting period: 86 PTs with significant disproportionality were retained. Infections including 'herpes zoster,' 'oral herpes,' and 'herpes virus infection' were found at a similar rate to those reported in trials, and such events were rare. Reports emerged for several thrombotic adverse events, while these events were also rare. Unexpected safety signals as opportunistic infections were detected. Serious outcomes as death and life-threatening outcomes accounted for 9.76% of the reported cases. CONCLUSIONS: The incidence of these AEs does not appear above the background expected. These data are consistent with routine clinical observations and suggest the importance of pharmacovigilance.

ABSTRACT

OBJECTIVES: To determine if a specific immunomodulatory intervention reduces progression of COVID-19-related disease to organ failure or death, compared to standard of care (SoC). TRIAL DESIGN: Randomised, parallel 3-arm (1:1:1 ratio), open-label, Phase IV platform trial of immunomodulatory therapies in patients with late stage 1 or stage 2 COVID-19-related disease, with a diagnosis based either on a positive assay or high suspicion of COVID-19 infection by clinical and/or radiological assessment. PARTICIPANTS: Patients aged 18 and over, with a clinical picture strongly suggestive of COVID-19-related disease (with/without a positive COVID-19 test) AND a Risk count (as defined below) >3 OR ≥3 if risk count includes "Radiographic severity score >3". A risk count is calculated by the following features on admission (1 point for each): radiographic severity score >3, male gender, non-white ethnicity, diabetes, hypertension, neutrophils >8.0 x109/L, age >40 years and CRP >40 mg/L. Patients should be considered an appropriate subject for intervention with immunomodulatory therapies in the opinion of the investigator and be able to be maintained on venous thromboembolism prophylaxis during the inpatient dosing period, according to local guidelines. The complete inclusion and exclusion criteria as detailed in the additional file 1 should be fulfilled. Patients will be enrolled prior to the need for invasive mechanical ventilation, cardiac or renal support. Participants will be recruited across multiple centres including initially at Cambridge University Hospitals NHS Foundation Trust, King's College Hospital NHS Foundation Trust, Guy's and St Thomas' NHS Foundation Trust, University Hospital of Wales, Gloucestershire Royal Hospitals NHS Foundation Trust and The Royal Wolverhampton NHS Trust. INTERVENTION AND COMPARATOR: Each active comparator arm will be compared against standard of care (SoC). The immunomodulatory drugs were selected from a panel of licenced candidates by a drug evaluation committee, which considered potential efficacy, potential toxicity, scalability and novelty of each strategy. The initial active arms comprise baricitinib and ravulizumab. Baricitinib will be given 4 mg orally (once daily (OD)) on days 1-14 or until day of discharge. The dose will be reduced to 2 mg OD for patients aged > 75 years and those with an estimated Cockcroft Gault creatinine clearance of 30-60 ml/min. Ravulizumab will be administered intravenously once according to the licensed weight-based dosing regimen (see Additional file 1). Each active arm will be compared with standard of care alone. No comparisons will be made between active arms in this platform trial. MAIN OUTCOMES: The primary outcome is the incidence (from baseline up to Day 14) of any one of the events (whichever comes first): death, invasive mechanical ventilation, extra corporeal membrane oxygenation, cardiovascular organ support (inotropes or balloon pump), or renal failure (estimated Cockcroft Gault creatinine clearance <15ml/min). RANDOMISATION: Eligible patients will be randomised using a central web-based randomisation service (Sealed Envelope) in a 1:1:1 ratio, stratified by site to one of the treatment arms or SoC. BLINDING (MASKING): This is an open-label trial. Data analysis will not be blinded. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): There is no fixed sample size for this study. Serial interim analyses will be triggered by an Independent Data Monitoring Committee (IDMC), including analysis after 125 patients are recruited to each arm, 375 in total assuming 3 arms. Additional interim analyses are projected after 229 patients per arm, and potentially then after 469 per arm, but additional analyses may be triggered by the IDMC. TRIAL STATUS: TACTIC-R Protocol version number 2.0 date May 20, 2020, recruitment began May 7, 2020 and the end trial will be the date 18 months after the last patient's last visit. The recruitment end date cannot yet be accurately predicted. TRIAL REGISTRATION: Registered on EU Clinical Trials Register EudraCT Number: 2020-001354-22 Registered: 6 May 2020 It was registered on ClinicalTrials.gov ( NCT04390464 ) and on ISRCTN (ISRCTN11188345) FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.

ABSTRACT

In December 2019, a novel coronavirus was identified in patients in Wuhan, China. The virus, subsequently named severe acute respiratory syndrome coronavirus-2, spread worldwide and the disease (coronavirus disease 2019 or COVID-19) was declared a global pandemic by the World Health Organization in March 2020. Older adults and individuals with comorbidities have been reported as being more vulnerable to COVID-19. Patients with chronic liver disease (CLD) have compromised immune function due to cirrhosis and are more susceptible to infection. However, it is unclear if patients with CLD are more vulnerable to COVID-19 and its complications than other populations. The high number of severe cases of COVID-19 has placed an unusual burden on health systems, compromising their capacity to provide the regular care that patients with CLD require. Hence, it is incredibly crucial at this juncture to provide a set of interim recommendations on the management of patients with CLD during the current COVID-19 outbreak.

ABSTRACT

A hyperinflammatory response to severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection, reminiscent of cytokine release syndrome, has been implicated in the pathophysiology of acute respiratory distress syndrome and organ damage in patients with coronavirus disease 2019 (COVID-19). Agents that inhibit components of the pro-inflammatory cascade have garnered interest as potential treatment options with hopes that dampening the proinflammatory process may improve clinical outcomes. Baricitinib is a reversible Janus-associated kinase (JAK)-inhibitor that interrupts the signaling of multiple cytokines implicated in COVID-19 immunopathology. It may also have antiviral effects by targeting host factors that viruses rely for cell entry and by suppressing type I interferon driven angiotensin-converting-enzyme-2 upregulation. However, baricitinib's immunosuppressive effects may be detrimental during acute viral infections by delaying viral clearance and increasing vulnerability to secondary opportunistic infections. The lack of reliable biomarkers to monitor patients' immune status as illness evolves complicates deployment of immunosuppressive drugs like baricitinib. Furthermore, baricitinib carries the risk of increased thromboembolic events, which is concerning given the proclivity towards a hypercoagulable state in patients with COVID-19. In this article, we review available data on baricitinib with an emphasis on immunosuppressive and antiviral pharmacology, pharmacokinetics, safety, and current progress in COVID-19 clinical trials.
