- BACKGROUND
2.1 Study Disease(s)
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus disease 2019 (COVID-19). Since initial detection of the virus, more than 10 million cases of COVID-19 have been confirmed worldwide, and COVID-19 is responsible for more than 505,500 deaths. The United States has seen over 2.5 million cases of COVID-19 and 126,000 deaths from this disease (as of June, 30, 2020). SARS-CoV-2 is efficiently transmitted from person-to-person and the World Health Organization (WHO) has declared coronavirus disease 2019 (COVID-19) to be a pandemic.
COVID-19 primarily spreads through the respiratory tract, by droplets, respiratory secretions, and direct contact. Current data suggest an incubation period of 1-14 days, in most cases 3-7 days. The virus is highly transmissible in humans and causes severe problems especially in the elderly and people with underlying chronic diseases. COVID-19 patients typically present with specific, similar symptoms, such as fever, malaise, and cough. Most adults or children infected with SARS-CoV-2 have presented with mild flu-like symptoms, but a few patients are in critical condition and rapidly develop acute respiratory distress syndrome (ARDS), respiratory failure, multiple organ failure, and death. The case fatality rate increases with the severity of illness and can reach up to 49% in critically ill patients.
Unfortunately, specific and effective therapies for COVID-19 are highly limited. Recent evidence suggest that administration of the anti-viral agent, Remdesivir, to hospital inpatients with COVID-19 decreases time to recovery from 15 to 11 days and decreases mortality at 14 days from 11.9% to 7.1%. A preliminary, unpublished analysis from a large, multicenter, randomized, open-label trial for hospitalized patients in the United Kingdom showed that patients who were randomized to receive dexamethasone had a reduced rate of mortality compared to those who received standard of care. This benefit was observed in patients with severe COVID-19 and was greatest in those who required mechanical ventilation at enrollment (RECOVERY Trial). These 2 agents are considered in the standard of care (SOC) for treating patients with COVID-19. However, additional therapies with larger effect sizes and that are administered at earlier stages to prevent progression to severe COVID-19 are critically needed.
2.1.1 IND (Investigational New Drug) Agent(s)
The PI has filed an IND with cross-reference letter from Novartis and has received a Safe to Proceed determination (IND #152065).The rationale for the proposed starting dose is based on the standard renal transplantation dose, which has a time-honored profile of safety in this population.
2.2 Rationale
Severe COVID-19. Initial reports from cases identified between February 12 to March 16 in the United States (U.S.) show rates of hospitalization for COVID-19 to be 21-31%, intensive care unit (ICU) admissions to be 5- 12%, and fatality to be 2%-3%. High-risk groups for severe COVID-19 have been identified as the elderly population and those with underlying comorbidities such as cardiovascular disease, liver disease, pulmonary disease, renal disease, and diabetes mellitus.
Severe COVID-19 results from a dysregulated hyperimmune state. Severe symptoms of COVID-19 are associated with a hyperimmune response referred to as a cytokine storm. In one study, all 41 patients with COVID-19 admitted to the hospital demonstrated elevated plasma levels of cytokines and chemokines compared with healthy volunteers that included IL (Interleukin) -1, -1R, -7, -8, -9, -10, and basic FGF2, GCSF, GMCSF, IFN-γ, IP10, MCP1, M1P1A, MIP1B, PDGF, TNF-α, and VEGF. Patients admitted to the ICU had higher levels of IL-2, IL-7, IL-10, GCSF, IP10, MCP1, MIP1A, and TNF-α than patients who did not require ICU admission. Emerging data has shown that early rapid SARS-CoV-2 replication causes massive epithelial and endothelial cell death that initiates a cytokine storm and vascular leakage, causes pyroptosis in macrophages and lymphocytes, and results in exhaustion of T cells and NK (Natural Killer) cells.
COVID-19 similarities to hemophagocytic lymphohistiocytosis (HLH). HLH is an under-recognized, hyperinflammatory syndrome characterized by a fulminant and fatal cytokine storm and multi-organ failure. In adults, HLH is most commonly triggered by viral infections and occurs in 3.7% to 4.3% cases of sepsis. Cardinal features include unremitting fever, cytopenias, and hyperferritinemia. Pulmonary involvement (including ARDS) occurs in ~50% of patients. Each of these clinical features and a highly overlapping cytokine profile is seen in severe COVID-19. This demonstrates that the clinical presentation and pathologic mechanisms of severe COVID-19 is similar to, or is HLH.
Cyclosporine (CSA) suppresses hyperimmune states. Calcineurin inhibitors such as CSA suppress the phosphatase activity of calcineurin, which results in decreased IL-2 production and IL-2 receptor expression. This interrupts a central pathway of T-cell activation and dampens T cell responses and their associated cytokine storms. CSA is approved by the FDA for three indications including 1) prophylaxis of organ rejection in kidney, liver, and heart transplants, 2) treatment of severe active rheumatoid arthritis, and 3) treatment of adult severe recalcitrant plaque psoriasis. It is critical to consider whether dampening of T-cell responses using CSA would curtail the vigor of T-cell hyperactivity in COVID-19 disease and provide an opportunity for these patients to recover.
CSA for COVID-19. Proposed is the use of the calcineurin inhibitor, CSA, for the treatment of patients with COVID-19. This is based on: 1) observations that COVID-19 disease is associated with a hyperimmune response very similar to HLH, for which treatment with CSA is effective and recommended, 2) COVID-19 is associated with dysregulated macrophage activation similar to macrophage activation syndrome (MAS) which is also therapeutically suppressed by CSA, and 3) in vitro studies demonstrating that CSA specifically inhibits the replication of coronaviruses including SARS-CoV-2 with a high degree of specificity.
CSA specifically inhibits coronavirus replication. Coronaviruses are RNA viruses with large genomes that enter host cells through binding of its transmembrane spike protein with angiotensin-converting enzyme 2 (ACE2) receptors expressed by host target cells, which is the same mechanism utilized by SARS-CoV (i.e., SARS). Cyclophilins appear to play a critical role in the replication of many viruses including coronaviruses, HIV, and hepatitis C virus. Although the exact mechanisms are not yet well understood, in vitro studies suggest that the coronavirus' nonstructural protein (Nsp) and nucleocapsid protein bind to cyclophilins, and knockdown of cyclophilin expression results in near complete inhibition of coronavirus replication. These data show that viral protein binding to cyclophilins is an important step for successful coronavirus replication, and inhibition of this interaction by CSA prevents viral replication. An important study demonstrated that CSA dominantly inhibited replication of human coronavirus 229E (HCoV-229E), mouse hepatitis virus (MHV), and SARS, and that treatment with increasing doses of CSA caused a dose-dependent decrease in SARS-CoV replication in human cells in vitro without affecting cell viability. The same group demonstrated that CSA inhibited replication of MERS-CoV without affecting cell viability of mock-infected cells. An independent group demonstrated that increasing concentrations of CSA treatment of SARS-CoV-infected human cells resulted in a dose-dependent decrease in viral replication, and inhibited the replication of other coronaviruses, including human CoV-NL63, CoV-229E, feline CoV serotypes I and II, porcine transmissible gastroenteritis virus (TGEV), avian infection bronchitis virus (IBV), and two isolates of SARS-CoV. Taken together it is proposed a dual mechanism in which (1) calcineurin inhibition by CSA inhibits the phosphorylation of NFAT-P, thus preventing the production of IL-2 and other proinflammatory cytokines, and (2) CSA inhibits viral replication of coronaviruses, likely through blockade of calcineurin, causing the inhibition of cyclophilins required for viral replication. Most recently, it was demonstrated that CSA is highly specific and effective at inhibiting SARS-CoV-2 replication in various human cells, via inhibition of Cyclophilin.
Safety of CSA in COVID-19. Since April 2020 mounting evidence from various patient populations has strongly suggested that CSA can be used safely in patients with COVID-19. It was recently demonstrated that patients with "Immune Mediated Inflammatory Diseases" (IMID) on various immunosuppressive drugs related to CSA have a "significantly reduced incidence of SARS-CoV-2 infection". It was reported no significant increase in the incidence or severity of COVID-19 disease in patients undergoing CSA therapy for Psoriasis, but rather suggested a potentially milder disease in these patients. Another study of over 4000 patients in Madrid, Spain demonstrated "a universal relationship between the use of Cyclosporine A and better outcomes" in patients with COVID-19 disease. In line with the findings from Spain, Cavagna in Italy observed that transplant patients with ongoing Calcineurin Inhibitor therapy developed only mild symptoms of COVID-19 disease and concluded that "Calcineurin inhibitor-based immunosuppressive regimens appear safe" in COVID-19 disease and should not be discontinued. These recent clinical outcomes data suggest that the use of CSA in patients with COVID-19 is safe and potentially effective.
2.3 Correlative Studies Background
Correlative studies in this protocol are included as secondary endpoints and are based on: 1) serum inflammatory markers used clinically as biomarkers to monitor the severity of COVID-19 (CRP, d-dimer, ferritin, ANC, absolute lymphocyte count, WBC (White Blood Cells), PLT), and 2) SARS-CoV-2 viral load by a clinical PCR (Polymerase Chain Reaction) test.
