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.

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

We hypothesize that recovered COVID-19 patients suffer long term cardiovascular and pulmonary complications, which can be detected by point of care ultrasound. The goal is to comprehensively delineate the long term cardiovascular and pulmonary ultrasound findings in recovered COVID-19 patients, identify risks factors for prolonged heart/lung injury, evaluate long term effects of applied treatment, and assess late medication/vaccine side effects in COVID-19 patients.

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.

In order to prevent reinfection, it is needed to detect the cellular-mediated immune response to the Sars-CoV-2 infection. The first goal of this study will be to detect the cellular-mediated immune response in patients affected by COVID-19 (with or without vaccination) and healthy subjects who undergone vaccination program. The second goal of this study will be to identify the genetic and epigenetic biomarkers that influence individual immunological response and clinical evolution to the severe manifestations of the COVID-19.

This study is meant to assess the lung mechanics in SARS-CoV-2 induced acute respiratory failure. A precise characterisation of lung mechanics and heart-lung-interactions might allow a better understanding of SARS-CoV-2 induced acute respiratory failure and thus lead to better mechanical ventilation strategies. This monocentric, observational study of critically ill COVID-19 patients in the ICU, will employ impedance tomography, right-heart catheterization, oesophageal pressure measurements, indirect calorimetry as well as classic mechanical ventilation parameters to characterise the mechanical characteristics of the lung as well as the heart-lung interactions in SARS-CoV-2 induced acute respiratory failure.
