A Double-blind, Multi-center, Multi-regional, Randomized controlled, Phase 3 Clinical Trial to Evaluate the Efficacy and Safety of CKD-314 in Hospitalized Adult Patients Diagnosed with COVID-19
Currently, several drugs including Remdesivir, hydroxychloroquine, chloroquine, ritonavir+lopinavir, Tocilizumab, Arbidol and interferon are under randomised controlled trials (RCTs) for efficacy and/or safety evaluations in patients with COVID-19 in different countries. Remdesivir (GS-5734) is among these investigational drugs and some studies reported promising results. Remdesivir is a nucleotide analogue intravenous pro-drug developed by Gilead Sciences, an American biopharmaceutical company, for treatment of Ebola virus during the 2014 Ebola outbreak in Western Africa. Remdesivir shows broad-spectrum antiviral activity against many RNA viruses including SARS-CoV-2 through blocking RNA polymerase thereby terminating RNA transcription. Remdesivir was among the first treatments used in China as the outbreak emerges and it has been reported as potential treatment options for COVID-19 in the USA, China and Italy.
The study will evaluate the immunogenicity, safety and efficacy of vaccines against severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) in oncohematological patient population and compare the results with patients without prior oncohematological disease. The study is comprised of retrospective and prospective parts. In retrospective part, biobanked residual biological patient material and data will be used. In prospective part, vaccinated oncohematological patients and vaccinated patients without prior oncohematological disease will be invited to participate in long-term follow-up. The subjects will be invited for blood sample collection every three months from the second vaccine dose administration, i.e. 3 mos., 6 mos., 9 mos. etc. When the study subject receives booster dose, additional blood samples for immunogenicity analyses will be collected up to 14 days before and 4-8 weeks after the booster vaccine dose. The follow-up time points occurring every three months will be counted from the last vaccine's dose. Ten time points in total will be collected and tested for humoral and cellular immunogenicity. For safety analysis patient self-documented systemic events (fever, fatigue, headache, chills, vomiting, diarrhea, new or worsened muscle pain, and new or worsened joint pain) occurring up to 7 days following each vaccine dose will be systematized and compared between oncohematological patients and healthy individuals. For efficacy analysis, polymerase chain reaction assay (PCR) confirmed symptomatic disease rates, hospitalization rates and mortality rates will be assessed.
This project seeks to test the efficacy of a brief eHealth intervention in an international randomized controlled trial (RCT) to increase COVID-19 knowledge and protective behaviors, and reduce psychological distress among LGBT people. This project involves enrolling racially diverse samples of lesbian, gay, bisexual and transgender people in three cities, randomizing 900 people (stratified among cisengender men, cisgender women, and transgender people) to either the immediate behavioral intervention or the waitlist control condition. Participants will complete a baseline survey, a follow-up survey 2 weeks post-intervention, and a final survey 2 months after the post-intervention survey. Primary outcomes are COVID-19 transmission knowledge, COVID-19 protective behaviors, and psychological distress.
COVID-19 poses a substantial risk to elderly populations; understanding how to get elders vaccinated against the virus is therefore a policy priority. An experiment with elders in Tamil Nadu, India will be used to evaluate interventions policymakers might use to raise vaccination rates amongst the elderly. The particular interventions being tested are: calling elders to inform them about vaccination; encouragement of a "buddy system," whereby elders are accompanied to the vaccination site by another adult who could also get the vaccine; and seeding vaccination information with "gossips," individuals who elders identify as being good at spreading information in the elders' communities. The interventions are phone-based, and can be implemented quickly and at low cost. This makes them promising strategies the Tamil Nadu government and other governments could use to vaccinate elderly populations against COVID-19.
Vaccination against the new coronavirus (SARS-CoV-2) was extended to patients at risk of severe forms of Covid-19, including in particular patients with autoimmune and inflammatory diseases treated by immunosuppressants and/or biologics. In this particular population, the effectiveness of vaccines, in particular influenza and pneumococcal vaccinations, is often reduced, especially in case of treatment with rituximab and / or methotrexate. Regarding the SARS-CoV-2 vaccine, the studies that allowed the marketing authorization of the available vaccines did not include patients treated with immunosuppressants or immunomodulators. Thus, the impact of treatments on the production of neutralizing antibodies and specific T lymphocytes is not known. The goal of this study is to assess the immune response to the SARS-CoV-2 vaccine in patients with autoimmune and inflammatory diseases treated with immunosuppressants or immunomodulators.
COVID-19 (SARS-CoV2 virus) was declared a global pandemic by the WHO on 11th March 2020. Currently there are no drugs proven to prevent COVID-19 or to reduce the severity of illness if given as prophylaxis. Although vaccines are now available, there remains a need for other prophylactic agents until vaccine use becomes widespread globally and effectiveness and durability is established, particularly in immunocompromised individuals, for whom vaccine responses may be suboptimal. Efforts are underway to repurpose established drugs with well understood drug interactions and safety profiles. PROTECT-V is a platform trial to test prophylactic interventions against SARS-CoV2 infection in vulnerable patient populations at particularly high risk of COVID-19 and its complications, seeking to identify treatments that either might prevent the disease from occurring or may reduce the number of cases where the disease becomes serious or life-threatening. In PROTECT-V, multiple agents can be evaluated on the same platform across vulnerable populations, with the option of adding additional treatments at later time points as these become available. The expectation is for as many sites as possible to recruit to all available trial treatments at any time, however, the platform structure and randomisation/data collection systems allow sites to open the trial treatment arms according to their capacity. The trial opened with intranasal niclosamide and matched placebo, aiming to recruit 1500 vulnerable renal patients in February 2021. A parallel study protocol, was conducted in India, sponsored by The George Institute. Recruitment of around 750 Indian patients was completed in with the rest of the study arm recruitment in November 2022. The Niclosamide arm of the study was completed in June 2023. The second agent, intranasal and inhaled ciclesonide and matched placebo, was meant to be added to the platform in mid-2022 in the same renal patient population however it was unable to be included due to other factor. Sotrovimab and matched placebo have been added to the platform in August 2022 which aim to recruit approximately 800-1000 patients from the main study population with additional patient groups with primary immunodeficiency, any Haematology or Oncology patient who is currently receiving or has received chemotherapy or who is immunocompromised as a result of their disease or treatment, those with a diagnosis of an autoimmune or inflammatory disease receiving immunosuppression and also haematopoietic stem cell transplant recipients.
The pandemic caused by the novel coronavirus SARS-CoV-2 has resulted in substantial global morbidity and mortality including in Oklahoma and caused unprecedented interruptions in nearly all aspects of our lives. The population of the state of Oklahoma is at particular risk to SARS-CoV-2 due to its large rural population, strained healthcare system, and poor overall health. The Community-Engaged Approaches to Testing in Community and Healthcare Settings for Underserved Populations (CATCH-UP) program will involve both practice-based and community-based approaches to maximize the reach of the RADx-UP consortium, broaden the potential perspectives that could be captured, and compare the effectiveness of strategies. The interventions will be pragmatic to allow CATCH-UP to respond to changing attitudes, barriers, and environments as the pandemic progresses as well as expected technology developments to produce more effective viral testing that can provide rapid results to patients. The investigators will assist 50 small primary care practices to implement guidelines-based testing and patient education about COVID-19 and risk mitigation strategies. The project's community-based approach is designed to rapidly respond to community testing needs by deploying mobile testing sites that will provide operational support to increase the efficiency and the existing capacity for state-wide testing by Oklahoma's public health authorities. Together, the investigators estimate that the CATCH-UP program will result in at least 105,000 SARS-CoV-2 tests performed during the first year of implementation. A comprehensive, ongoing evaluation will be performed to analyze patient and provider attitudes, barriers and facilitators of viral testing, identified health disparities caused by COVID-19, effectiveness of the intervention in both settings, and to allow robust collaboration with other RADx-UP consortium sites.
