Timing of of corticosteroids administration is very important in COVID19 cases for therecovery and decrease the mortality.

The primary objective of this study is to provide expanded access of S-nitrosylationtherapy for the treatment of severe acute respiratory syndrome coronavirus (SARS-CoV2)infection.

Time to recover of Anosmia and / or ageusia and early corticosteroid use

This study is an open-label, single-arm study to evaluate the safety and efficacy ofAstrostem-V, allogenic adipose tissue derived mesenchymal stem cells (AdMSC), in patientswith COVID-19 pneumonia. After each subject completes 12-Weeks visit (Visit 12) and thedata management team confirms all individual data have no issue, the individual databasewill be locked and the blinding will be open for the statistical analysis.

Prospective, single center, randomized, open label, parallel group, 2-arm study assessingthe clinical benefit in term of enhancement of overall response rate of Isatuximab incombination with CellProtect as compared to Isatuximab for the treatment of patients withnewly diagnosed multiple myeloma who are eligible for stem cell transplantation (SCT) asmaintenance after SCT.

The Can nebulised HepArin Reduce morTality and time to Extubation in Patients withCOVID-19 Requiring mechanical ventilation Meta-Trial (CHARTER-MT) is a prospectivecollaborative individual patient data analysis of randomised controlled trials and earlyphase studies. Individual studies are being conducted in multiple countries, includingAustralia, Ireland, the USA, and the UK.Mechanically ventilated patients with confirmed or strongly suspected SARS-CoV-2infection, hypoxaemia and an acute pulmonary opacity in at least one lung quadrant onchest X-ray, will be randomised to nebulised heparin 25,000 Units every 6 hours orstandard care (open label studies) or placebo (blinded placebo controlled studies) for upto 10 days while mechanically ventilated. All trials will collect a minimum core dataset.The primary outcome for the meta-trial is ventilator-free days during the first 28 days,defined as being alive and free from mechanical ventilation. Individual studies may haveadditional outcomes.

Background: There are no proven therapies specific for pulmonary dysfunction in patientswith acute hypoxemic respiratory failure (AHRF) caused by infections (includingCovid-19). The full spectrum of AHRF ranges from mild respiratory tract illness to severepneumonia, acute respiratory distress syndrome (ARDS), multiorgan failure, and death. Theefficacy of corticosteroids in AHRF and ARDS caused by infections remains controversial.Methods: This is a multicenter, randomized, controlled, open-label clinical trial testingdexamethasone in mechanically ventilated adult patients with established AHRF (includingARDS) caused by confirmed pulmonary or systemic infections, admitted in a network ofSpanish ICUs. Eligible patients will be randomly assigned to receive dexamethasone:either 6 mg/d x 10 days or 20 mg/d x 5 days followed by 10 mg/d x 5 days. The primaryoutcome is 60-day mortality. The secondary outcome is the number of ventilator-free daysat 28 days. All analyses will be done according to the intention-to-treat principle.

Currently, there is no approved treatment for COVID-19 in France, either for the acutephase, nor for the late chronic phase. the investigator suggest that nintedanib has thepotential to block the development of lung fibrosis when initiated early enough toinhibit the activation of mesenchymal cells and the progression of virus-inducedpulmonary fibrosis. Computerized Tomography (CT) manifestations of fibrosis or fibrousstripes are described in COVID-19 (Ye, Eur Radiol 2020). Pan et al observed fibrousstripes in 17% patients in the early phase of the disease (Pan, Eur Radiol 2020). Ye etal observed bronchiectasis in 2 patients (15.4%) and evidence of pulmonary fibrosis in 3patients (23.7%) at HRCT performed at 4 weeks (Ye, Eur Radiol 2020). Long term data arestill lacking in patients with COVID-19 and the investigators do not know how manypatients will have fibrotic sequelae from the acute illness.

The primary objective of this study is to evaluate the effect of additional estradiolestrogen therapy on clinical response and mortality in non-severe COVID-19 patients

This is an open-label, randomized, multi-centre study where hospitalized subjects will berandomized in a 2:1 ratio to receive Isoquercetin (IQC-950AN) in addition to standard ofcare or standard of care only for 28 days following confirmation of a COVID-19 infection.
