Brief summary

This phase I/IIa trial studies the best dose and side effects of rintatolimod and interferon (IFN) alpha-2b in treating cancer patients with COVID-19 infection. Interferon alpha is a protein important for defense against viruses. It activates immune responses that help to clear viral infection. Rintatolimod is double stranded ribonucleic acid (RNA) designed to mimic viral infection by stimulating immune pathways that are normally activated during viral infection. Giving rintatolimod and interferon alpha-2b may activate the immune system to limit the replication and spread of the virus.

Detailed description

PRIMARY OBJECTIVES: I. To determine the safety of the combination of intravenous (i.v.) rintatolimod administered with or without i.v. IFN alpha (recombinant interferon alfa-2b \[Intron A\]) in patients with cancer with coronavirus disease 2019 (COVID-19). II. Determine the kinetics of viral load in nasopharyngeal swabs in the course of treatment and Days 7 and 14. SECONDARY OBJECTIVES: I. To assess the efficacy of the treatment combination in patients with cancer with COVID-19. II. Determine the kinetics of viral load in the peripheral blood in the course of treatment and Days 7 and 14. III. Determine the kinetics of changes of the immune subsets and circulating inflammatory mediators (including C-reactive protein \[CRP\], cytokines, chemokines, interferons) in peripheral blood in the course of treatment and Days 7 and 14. IV. Determine the induction of known mediators of antiviral immunity that include (myxovirus resistance gene, MxA; protein Kinase R (PKR); oligoadenylate synthetase-2 (OAS2); RNAse-L, IFN-stimulated gene-15 (ISG15); IFN-induced proteins with tetratricopeptide repeats (IFIT1) and IFN-inducible transmembrane protein 3 (IFITM3), TLR3, RIG-I, MDA5, IRF3, IRF7, in nasopharyngeal swabs material and blood cells of patients on all tiers of treatment. OUTLINE: This is a phase I, dose-escalation study of recombinant interferon alfa-2b followed by a phase II study. LEAD-IN PHASE: Patients receive rintatolimod IV over 2.5-3 hours on day 1 and day 3 (or 4). ARM I: Patients receive rintatolimod IV over 2.5-3 hours and recombinant interferon alfa-2b IV over 20 minutes on day 1 and on day 3 or 4 in the absence of disease progression or unacceptable toxicity. EXPANSION COHORT: ARM III: Patients receive rintatolimod IV over 2.5-3 hours along with standard of care. Patients are followed up at days 7, 14 and 30 after initiation of the study regimen.

Inclusion criteria

* INCLUSION CRITERIA (MAIN COHORT): * Patients with cancer, with the exception of patients with active acute leukemia and allogeneic hematopoietic stem cell transplant recipients. Patients may be on active therapy or received therapy (e.g., chemotherapy, radiation or surgery) within 7 years. Patients with active cancer who have not yet been treated (e.g. newly diagnosed cancer or early stage myelodysplastic syndrome \[MDS\] or chronic lymphocytic leukemia \[CLL\]) are eligible. Basal cell cancer and carcinoma in situ treated with local excision alone do not qualify for inclusion * Presence of symptomatic infection, defined by fever (temperature \[T\] \>= 38 degrees Celsius \[C\]) OR respiratory symptoms (cough, nasal congestion, or shortness of breath) OR lung infilitrates on chest X-ray or CT imaging. Diagnosis of COVID-19 is based on polymerase chain reaction (PCR) testing of respiratory samples. * Age equal to \>= 18 years or older (children are excluded because COVID-19 typically has a milder course in children, and lack of safety data of this regimen in children) * Platelet \>= 75,000/uL * Hemoglobin \>= 9 g/dL * Hematocrit \>= 27% * Absolute neutrophil count (ANC) \>= 1000/uL * Creatinine clearance \>= 50 mL/min (Cockcroft-Gault Equation-note: plasma creatine instead of serum is used at Roswell Park) * Total bilirubin =\< 2 X institutional upper limit of normal (ULN) * Aspartate transaminase (AST) (plasma) and alanine transferase (ALT) (plasma) =\< 2 X institutional ULN * Plasma amylase and lipase =\< 2 X institutional ULN * In the absence of COVID-19, a life expectancy of 6 months is expected * Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure * NOTE: For blood chemistry labs, Roswell Park clinical blood chemistries are performed on plasma unless otherwise indicated * EXPANSION COHORT: Patients with cancer or allogeneic stem cell transplant recipients with and without a cancer diagnosis * Patients with cancer may be on active therapy or received therapy (e.g., chemotherapy, radiation or surgery) within 7 years * Patients with active cancer who have not yet been treated (e.g. newly diagnosed cancer or early stage MDS or CLL) are eligible * Basal cell cancer and carcinoma in situ treated with local excision alone do not qualify for inclusion * Presence of symptomatic infection, defined by fever (T \>= 38.0 degrees C ) OR respiratory symptoms (cough, nasal congestion, or shortness of breath) OR lung infiltrates by chest X-ray or CT imaging. Diagnosis of COVID-19 is based on PCR testing of respiratory samples. Severe infection is excluded * Age equal to \>= 18 years or older (children are excluded because COVID-19 typically has a milder course in children, and lack of safety data of this regimen in children). In the absence of COVID-19, a life expectancy of 6 months is expected * Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure. There may be specific instances when the patient can't provide informed consent, e.g. they require mechanical ventilation and are sedated, in which case a health care proxy will be able to provide informed consent. Patients with temporary cognitive impairment will be consented once their capacity has returned. Patients with chronic cognitive impairment, e.g. dementia, that precludes informed consent will not be enrolled.
