Around the world, researchers are working extremely hard to develop new treatments and interventions for COVID-19 with new clinical trials opening nearly every day. This directory provides you with information, including enrollment detail, about these trials. In some cases, researchers are able to offer expanded access (sometimes called compassionate use) to an investigational drug when a patient cannot participate in a clinical trial.
The information provided here is drawn from ClinicalTrials.gov. If you do not find a satisfactory expanded access program here, please search in our COVID Company Directory. Some companies consider expanded access requests for single patients, even if they do not show an active expanded access listing in this database. Please contact the company directly to explore the possibility of expanded access.
Emergency INDs
To learn how to apply for expanded access, please visit our Guides designed to walk healthcare providers, patients and/or caregivers through the process of applying for expanded access. Please note that given the situation with COVID-19 and the need to move as fast as possible, many physicians are requesting expanded access for emergency use. In these cases, FDA will authorize treatment by telephone and treatment can start immediately. For more details, consult FDA guidance. Emergency IND is the common route that patients are receiving convalescent plasma.

This project will provide novel data using a large cohort of more than 3000 transplanted patients. Risk and protective factors for SARS-CoV-2 infection and COVID-19 disease severity will be identified. The proportion of patients who develop antibodies after infection will be revealed. In this way the presence of these antibodies can be evaluated as a test for prior infection. Our study additionally will demonstrate how long these antibodies remain present and whether they are protective against a new infection.

Combination of Chemopreventive agents (All- Trans Retinoic Acid and Tamoxifen) as potential treatment for the Lung Complication of COVID-19 Abstract Angiotensin-converting enzyme (ACE2) protein found on the cell membranes is the target of SARS-CoV-2 for entering into the host cells. Viral spike protein-binding with ACE2 down-regulates it. As ACE2 is known to protect the lung from injuries, SARS-CoV-2-induced ACE2 deficiency may expose patients to lung damage. In this Review, we use established and emerging evidence based on the findings of previous studies and researches to propose a testable hypothesis that Combination of chemopreventive agents (All Trans Retinoic acid and Tamoxifen) can be tested to prevent inflammatory complication in severe acute respiratory syndrome coronavirus 2 infection via two mechanisms by inhibiting bradykinin B1,B2 receptors expression and upregulating the depleted ACE2 in COVID-19 . Bradykinin B1 receptors are not expressed under physiological conditions but are induced under inflammatory conditions. Here we hypothesize that permanent attack and invasion of COVID-19 to lung epithelial cells via binding to ACE2 leads to tissue injury and inflammation and that increases BK levels and BK-B2-receptor (B2R) stimulation A study reported that tissue injury and inflammation increases BK levels and BK-B2-receptor (B2R) stimulation. We suggest that Bradykinin mediates and induces lung injury, proinflammatory cytokines and inflammation likely precipitates life threatening respiratory complications in COVID-19. Further experiments showed that BK treatment stimulated IL-6 production On the other hand a study reported that cells treated with Retinoic acid and Tamoxifen for 48 h significantly decreased the BK-B2 receptor protein levels (70.3 ± 0.6% vs. 100% of control, P < 0.05). Retinoids inhibit bradykinin B1 receptor-sensitized responses and this action could participate in their anti-inflammatory and immunomodulatory effects. In addition retinoic acid, is known to possess in vivo anti-inflammatory, anti-platelet and fibrinolytic activities. A study investigated the in vitro thrombin and platelet aggregation inhibitory activities of retinoic acid and retinaldehyde.Retinoic acid, retinaldehyde and retinol exhibited potent inhibition of thrombin, with IC50 values of 67μg/ml, 74μg/ml and 152μg/ml, respectively for the inhibition of thrombin (Sigma); and 49μg/ml, 74μg/ml and 178μg/ml, respectively for the inhibition of thrombin (plasma). Amongst vitamin A and its derivatives, retinoic acid showed the highest inhibition of both the forms of thrombin. Beside the effectiveness of TAM on cancer cells, it also has other effects on numerous microbes including parasite, fungi, bacteria, and some viruses such as Ebola virus and human immunodeficiency virus (HIV).Furthermore Tamoxifen can block the action of interleukin 6 and inhibit neutrophils. A study demonstrated that tamoxifen has side effects associated with neutropenia. Since tamoxifen can cause neutropenia and subsequently influence the neutrophil-to-lymphocyte ratio (NLR) value In addition it has anti malarial effect similar to chloroquine In conclusion Keywords: COVID 2019 , Retinoic acid, Endosomal toll-like receptor 3,T Cells, IFN type1, AT1, ACE2,TMPRSS2

Based on the literature, it seems likely that a nutritional intervention with nicotinamide (a form of vitamin B3) can support the therapy of SARS-CoV-2 infection (COVID-19). A pilot phase of the COVit trial showed an effect of nicotinamide on the time to complete resolution of COVID-19 symptoms. In addition, diarrhoea is a common symptom of COVID-19. Therefore, in a second part of the study, 420 symptomatic patients each with confirmed SARS-CoV-2 infection are to take 1,000 mg nicotinamide (500 mg conventional nicotinamide and 500 mg nicotinamide released in a controlled manner in the intestine) or corresponding placebos per day in a blinded fashion for 4 weeks. The primary endpoint of the trial is the occurrence of individual COVID-19 symptoms over time (primary analysis time point: week 2). Secondary endpoints focus on the severity of COVID-19 symptoms, the post-COVID-19 syndrome (PCS), anti-SARS-CoV-2 antibody levels, and the time to resolution of individual or all symptoms. Exploratory endpoints include the WHO clinical scale for COVID-19, development of severe COVID-19, fatigue, quality of life and biomarkers. Patients are approached after positive testing and give their informed consent online. After randomised distribution of the trial supplements, patients are interviewed by telephone about their disease course at baseline (week 0), week 2, week 4, week 6 and after 6 months. Stool samples are collected from up to 400 patients at the same timepoints. In addition to blood count and standard blood profile, various inflammatory markers and the metabolome, in particular tryptophan metabolism, are examined in the blood of up to 20 selected patients. In these patients, the viral strain is determined by sequencing from nasopharyngeal swabs. In selected patients, short-term pharmacokinetics of nicotinamide, nicotinic acid and nicotinuric acid as well as of metabolites of nicotinamide and tryptophan are investigated. In the stool, changes in the microbiome (in 100-300 patients) as well as metagenome and metabolome (in a subgroup) will be analysed. The study is expected to produce rapid results on whether nicotinamide supplementation can alleviate the disease course of COVID-19. Moreover, a follow-up interview, a smell test, a cognitive test and anti-SARS-CoV-2 antibody levels after at least 6 months will be used to investigate whether the supplementation has any influence on PCS as well as the immune reaction against SARS-CoV-2.

Stopping the SARS-CoV2 spread is essential to control the pandemic cause by this virus. A great effort is being made to carry out surveillance, case detection and contact control protocols in order to detect and isolate those contagious subjects. Since both symptomatic and asymptomatic subjects can be contagious, a surveillance system based on the presence of symptoms is not enough, requiring to perform diagnostic tests in a large number of subjects, such as asymptomatic contacts or high-prevalence populations, and repeatedly. Moreover, the speed in obtaining results is crucial in order not to delay the isolations of positive subjects. The polymerase chain reaction (PCR) is an expensive test which requires specialized equipment and personnel with a delay in results of 24-48 hours. In addition, its high sensitivity can mean that subjects without infective capacity have a positive result. In contrast, antigen detection tests (ADTs) are cheap and easy to perform, having a result in few minutes. They have shown high sensitivity and specificity in symptomatic subjects, specially in the first week of symptoms when the viral load is high. This could be very useful for the study of asymptomatic contacts to detect those with potential contagiousness quick, easily and cheaply. However, there is no evidence to support the use of ADTs in this group of subjects. For this reason, the investigators propose to carry out a study to compare the diagnostic efficacy of ADTs versus PCR in the group of subjects considered to be close contacts of SARS-Cov2 positive patients in the health area of Cáceres.

COVID-19 is known to affect the respiratory system but may also have an impact on other organ systems, including the brain. A number of severely ill patients also presents neurological symptoms that may be the result of COVID-19 associated brain damage. The aim of this study is to investigate the presence, type, and severity of brain damage as well as the neurological and neuropsychological sequelae of COVID-19 infection. Further, the impact of this infection on daily life functioning, quality of life, and the emotional well-being of family members will be assessed. In this multicenter study, 6-9 months after hospital discharge patients will undergo a 3-T MRI scan and a neuropsychological examination. Additionally, both patients and their family members will answer several questionnaires at 6- 9 and 12-15 months after hospital discharge. COVID-19 patients previously admitted to a general hospital ward will be compared with patients previously admitted to the intensive-care unit. The proposed study will create a more comprehensive picture of the prolonged COVID-19 effects on the brain, mental, and cognitive well-being. The findings will aid patient care and rehabilitation.
