A prior open label study has shown that transcutaneous vagus nerve stimulation [tVNS] can improve the health of some patients with postacute sequelae of SARS-CoV-2 infection (PASC), severely affected enough to also fulfill criteria for myalgic encephalomyelitis / chr...

The platform protocol is designed to be flexible so that it is suitable for a range of study settings and intervention types. Therefore, the platform protocol provides a general protocol structure that can be shared by multiple interventions and allows comparative an...

COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the dise...

The goal of this clinical study is to test if obeldesivir (formerly GS-5245) is safe and effective for the treatment of coronavirus disease 2019 (COVID-19) in participants who have a standard risk of developing severe illness. This study will also measure how much o...

Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-lik...

The primary objective of the study is to evaluate the effect of casirivimab+imdevimab, compared with placebo, in preventing symptomatic SARS-CoV-2 infection in immunocompromised participants. The secondary objectives of the study are: - To evaluate the safety and tolera...

Substudy A: The study will evaluate the safety, tolerability, and efficacy of a booster dose of BNT162b2 when administered to participants having previously received 2 doses of BNT162b2 at least 6 months prior to randomization. The study is designed to describe ...

The primary objective of the Outpatient Treatment with Anti-Coronavirus Immunoglobulin (OTAC) (INSIGHT 012) trial is to compare the safety and efficacy of a single infusion of anti-COVID-19 hyperimmune intravenous immunoglobulin (hIVIG) versus placebo among adults wi...

The purpose of this research study is to identify patients with GU disease with active or past COVID-19 infection. Participants will be asked to: - Complete an Online COVID-19 Questionnaire. - Disclose if the patient has or had Genitourinary cancer or beni...

Leveraging a natural experiment approach, the investigators will examine rapidly changing telemedicine and in-person models of care during and after the COVID-19 crisis to determine whether certain patients could safely choose to continue telemedicine or telemedic...

There is surge in COVID infected patients in New York City with a shortage of hospital beds, ICU beds and ventilators. Strategies to reduce the need for all of the above are immediately needed. Further, few interventions are targeted in COVID infected patients early...

Endothelial injury as a consequence of SARS-CoV-2 infection leads to a dysregulated host inflammatory response and activation of coagulation pathways. Macro- and micro-vascular thrombosis may contribute to morbidity, organ failure, and death. Therapeutic anticoagulati...
