Current Primary Outcome Measures ICMJE |
Biological response [ Time Frame: At 28 days post the second vaccine injection ] Based on at least a 3-fold increase in severe acute respiratory syndrome coronavirus 2 (SARSCoV-2)- neutralizing antibodies or interferon (IFN)-gamma levels. Will compare the immune response at day 28 post the second injection between GEO-CM04S1 and SOC mRNA SARS-CoV-2 vaccine using a one-sided stratified Cochran-Mantel-Haenszel test. The point estimate and 95% confidence interval will be calculated per arm for immune response at day 28 post the second injection. Bar charts will be generated to show the immune response rate by arm overall, and by arm and strata.

Official Title ICMJE | A Phase 2 Randomized, Multi-center Study of GEO-CMO4S1 (SARS-CoV-2 Vaccine) Versus mRNA SARS-CoV-2 Vaccine in Patients Post Cellular Therapy for Hematological Malignancies | ||||||||
Brief Summary | This phase 2 trial studies the immune response to GEO-CM04S1 (previously designated as COH04S1) compared to standard of care (SOC) mRNA SARS-COV-2 vaccine in patients with blood cancer who have received stem cell transplant or cellular therapy. GEO-CM04S1 belongs to a category called modified vaccinia Ankara (MVA) vaccines, created from a new version of MVA, called synthetic MVA. GEO-CM04S1 works by inducing immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The immune system is stimulated to produce antibodies against SARS-CoV-2 that would block the virus from entering healthy cells. The immune system also grows new disease fighting T cells that can recognize and destroy infected cells. Giving GEO-CM04S1 after cellular therapy may work better in reducing the chances of contracting coronavirus disease 2019 (COVID-19) or developing a severe form of COVID-19 disease in patients with blood cancer compared to SOC mRNA SARS-CoV-2 vaccine. |

Detailed Description | PRIMARY OBJECTIVE: I. Evaluate the biological activity and the role of timing of 2 injections of GEO-CM04S1 vaccine administered at 2.5e8 PFU/dose compared to SOC mRNA vaccine. SECONDARY OBJECTIVES: I. Assess safety of GEO-CM04S1 vaccine. II. Evaluation of SARS-CoV-2 S and N-specific Th1 vs Th2 polarization. III. Evaluate T-cell levels and function. IV. Evaluate activated/cycling and memory phenotype markers. V. Evaluate durability of immune responses. VI. Evaluate maintenance of immunity that can be associated with protection over the study period. EXPLORATORY OBJECTIVE: I. Surveillance for incidental COVID-19 infection during follow-up (1 year). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I : Patients receive one dose of GEO-CM04S1 intramuscularly (IM) in the upper arm on days 0 and 28. ARM II : Patients receive one dose of SOC mRNA SARS-CoV-2 vaccine IM in the upper arm on days 0 and 28. After the completion of study treatment, patients are followed up at days 7, 90, 120, 180, and 365. |
