17 Clinical Trials for Various Conditions
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
This study looks at the safety and effectiveness of Aviptidil in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with Aviptidil plus current standard of care (SOC), or with placebo plus current SOC.
This study looks at the safety and effectiveness of Remdesivir in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with Remdesivir plus current standard of care (SOC), or with placebo plus current SOC.
The purpose of the study is to evaluate whether ibuzatrelvir is effective and safe in adults and adolescents with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible participants will be randomly assigned (by chance) to receive ibuzatrelvir or matching placebo orally for 5 days. Co-administration of locally available standard of care is allowed. The total duration of the study is around 6 months.
Chronic olfactory dysfunction, both hyposmia and parosmia, from the COVID-19 pandemic is a growing public health crisis with up to 1.2 million people in the United States affected. Olfactory dysfunction impacts one's quality of life significantly by decreasing the enjoyment of foods, creating environmental safety concerns, and affecting one's ability to perform certain jobs. Olfactory loss is also an independent predictor of anxiety, depression, and even mortality. Recent research by our group (unpublished data) and suggests that parosmias, moreso than hyposmias, can result in increased rates of anxiety, depression, and even suicidal ideation. While the pandemic has increased the interest by the scientific community in combating the burgeoning health crisis, few effective treatments currently exist for olfactory dysfunction. Persistent symptoms after an acute COVID-19 infection, or "Long COVID" symptoms, have been hypothesized to be a result of sympathetic positive feedback loops and dysautonomia. Stellate ganglion blocks have been proposed to treat this hyper-sympathetic activation by blocking the sympathetic neuronal firing and resetting the balance of the autonomic nervous system. Studies prior to the COVID-19 pandemic have supported a beneficial effect of stellate ganglion blocks on olfactory dysfunction, and recent news reports and a published case series have described a dramatic benefit in both olfactory function and other long COVID symptoms in patients receiving stellate ganglion blocks. A previous pilot study using stellate ganglion blocks of 20 participants with persistent COVID-19 olfactory dysfunction resulted modest improvements in subjective olfactory function, smell identification, and olfactory-specific quality-of-life, but it lacked a control group. Therefore, we propose a double-blinded, placebo-controlled randomized clinical trial assessing the efficacy of a stellate ganglion block versus saline injection in a total of up to 140 participants with persistent COVID-19-associated olfactory dysfunction.

Participants in the study will be treated with either MP0420 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H5.
This study looks at the safety and effectiveness of AZD7442 in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either a AZD7442 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H4.
This study looks at the safety and effectiveness of BRII-196/BRII-198 in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either BRII-196/BRII-198 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H3.
This study looks at the safety and effectiveness of VIR-7831 in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either VIR-7831 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H2.
This study looks at the safety and effectiveness of LY3819253 in treating COVID-19 in people who have been hospitalized with the infection. Participants in the study will be treated with either LY3819253 plus current standard of care (SOC), or with placebo plus current SOC. This is ACTIV-3/TICO Treatment Trial H1.
A Study to Learn About the Medicine Called Nirmatrelvir Used in Combination With Ritonavir in People with Weakened Immune Systems or at Increased Risk for Poor Outcomes who are Hospitalized Due to Severe COVID-19
In this Phase 4, open-label trial, participants of the ACTIV-3/TICO clinical trial at selected sites who received certain pre-specified blinded investigational agents or placebo as part of that trial, and who have since achieved sustained recovery, and who are still \[TICO assignment\] blinded and who are still within 28 to 90 days after initial TICO randomization, will be randomized in this 2x2 factorial design to one of four groups: (i) immediate versus 12 week deferral of first dose administration and also (ii) one dose only, versus two doses to be given 4 weeks apart of the Moderna mRNA-1273 or the Pfizer BNT162b2 vaccine (mRNA vaccines). Choice of Moderna or Pfizer vaccine is determined based on availability at the site. The choice is individual, although participants vaccinated twice should receive the same type of vaccine for both injections. The primary objectives of this 2x2 factorial design are (i) to estimate the difference in neutralizing antibody (NAb) response to the mRNA vaccine from baseline to Week 48 among participants vaccinated early versus deferred, and (ii) to estimate the difference in NAb response to this vaccine among participants vaccinated once versus twice. The primary analyses will be carried out in participants randomized to placebo in TICO. Analyses will also be carried out for those who receive the investigational agent(s) studied in TICO. A key secondary objective is to ascertain the effect, if any, of SARS-CoV-2 monoclonal antibodies, and other interventions that have been studied in hospitalized COVID-19 subjects, on natural and vaccine-induced immunity. Participants will remain blinded to the interventions received in the ACTIV-3/TICO study, however allocation to the timing of vaccination and to one or two vaccinations in this (VATICO) study is not blinded.
This study looks at the safety and effectiveness of different drugs in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with either a study drug plus current standard of care (SOC), or with placebo plus current SOC.
Drug studies often look at the effect one or two drugs have on a medical condition, and involve one company. There is currently an urgent need for one study to efficiently test multiple drugs from more than one company, in people who have tested positive for COVID-19 but who do not currently need hospitalization. This could help prevent disease progression to more serious symptoms and complications, and spread of COVID-19 in the community. This study looks at the safety and effectiveness of different drugs in treating COVID-19 in outpatients. In Phase II, participants in the study will be treated with either a study drug or with placebo. In protocol version 7.0, participants in Phase III of the study will be treated with either a study drug or active comparator drug. Participants assigned to the bamlanivimab agent/placebo arm and will have 28 days of intensive follow-up following study drug administration, followed by limited follow-up through 24 weeks in phase II and in phase III. All other investigational agents and their corresponding placebo arms will involve 28 days of intensive follow-up, followed by limited follow-up through 72 weeks in phase II and phase III. Additional study visits may be required, depending on the agent.
