COVID-19 Clinical Trials and Expanded Access

Hope Biosciences is conducting a research study of an investigational product called allogeneic adipose-derived mesenchymal stem cells (abbreviated as HB-adMSCs) as treatment for patients suspected to have COVID-19. The study purpose is to evaluate the safety and efficacy of four IV infusions of either placebo or HB-adMSCs in subjects with COVID-19.

Starting an early home management and monitoring of patients with suspected or confirmed COVID-19 to ensure a rapid and adequate transfer to hospital care. Assess the feasibility of home monitoring in a pilot study to possibly extend it to a larger scale.

In November 2019, Wuhan city in China, became the center of an outbreak of pneumonia due to a novel coronavirus SARS-CoV-2, which disease was named coronavirus disease 2019 (COVID19) in February, 2020. The COVID19 is much more dangerous for people over 60 with a death rate of 3.6% after 60, 8.0% after 70 and 14.8% after 80 -and according to our Italian colleagues over 20% after 90- against 2.3% in the general population. The elderly patients who died most often had multiple comorbidities and in particular: cardiovascular disease (10.5% mortality), diabetes (7.3%), chronic respiratory disease (6.3%) and hypertension (6%). These elderly patients with COVID19 are therefore very fragile and require treatment that fights the virus but is also adapted to their state of health and age. Most of current therapeutic trials worldwide exclude people aged over 75 years, which is precisely the age group affected by COVID19. We therefore propose to carry out a therapeutic trial specific to the elderly with drugs at doses that are bearable for these patients. Using the WHO, clinicaltrial, pubmed and the Chinese CCDC/CHCTR websites to find the better drugs adapted to elderly people, we decided after concertation between infectiologists and geriatricians to do a four arms clinical trial during two weeks twice a day: Hydroxychloroquine 200mg, Telmisartan 40mg, Azithromycin 250mg and standard care. We therefore hypothesize that one or more of these treatments may have a beneficial effect in controlling COVID19, without major and repeated side effects in elderly patients.

This is a randomized, open label, adaptive platform trial to compare the effectiveness of antithrombotic and additional strategies for prevention of adverse outcomes in COVID-19 positive inpatients

Rationale: Currently there are no approved treatments for COVID-19. In the Dutch treatment protocol guideline (SWAB) designated treatment is supportive care with the option to add chloroquine base (CQ) or hydroxychloroquine (HCQ). CQ and HCQ are implemented because of their in vitro activity, results from small animal studies, and anecdotal patient's data. There are no published randomized studies with these medications in patients with disease caused by any coronavirus. Objective: To evaluate if treatment with only supportive care or addition of one of two anti-COVID_19 agents (chloroquine or hydroxychloroquine) results in less disease progression in patients with moderate to severe COVID-19 who require hospital admission. Study design: Multicentre, cluster randomized cross-over, open label trial. Hospitals will be randomly allocated to one of 3 treatment arms in sequential periods of one week: chloroquine base versus hydroxychloroquine versus supportive care without any drug presumed active against SARS-COV-2. Patients will be treated based on the date of inclusion. Study population: Adults aged of 18 years and older with moderate to severe, with a NEWS-2 score ≤ 5, laboratory confirmed COVID-19, who require hospital admission in a ward outside the Medium Care or Intensive Care. Intervention (if applicable): Depending on the treatment arm, the study subject will receive only supportive care or an addition with one of the two agents active against SARS-CoV-2 (chloroquine or hydroxychloroquine). Main study parameters/endpoints: Disease progression defined as a NEWS-2 score ≥ 7 within 14 days, or admission to Medium Care or Intensive Care Unit, or death.

This study will enroll 40 symptomatic outpatients tested positive for Coronavirus 2019 (COVID-19). Patients to be randomized 1:1 to Telmisartan (40 mg) vs placebo to be administered orally once daily x 21 days. Daily, the study patients will be asked to keep a record of the severity of their fever, dyspnea and fatigue and take their blood pressure (BP) and temperature. Study visits to occur on day 1 (entry), day 4, day 10 and day 21. Oro-pharyngeal swabs, and approximately 25 cc of blood will be collected at each study visit for safety labs and for the evaluation of the renin-angiotensin system (RAS) system and for various blood biomarkers of inflammation, coagulation and fibrosis.

This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, is shed in the stools of patients who are infected.

This is a prospective observational registry of COVID-19 recovered patients who are no longer symptomatic. This Registry is intended to serve as a pool of individuals that can participate in studies associated with serological testing, characterization of immunity and immune response, vaccine development, and convalescent plasma donors.

Trial to Evaluate the Efficacy and Safety of Nitazoxanide (NTZ) for Pre- and Post Exposure Prophylaxis of COVID-19 and Other Viral Respiratory Illnesses (VRI) in Healthcare Workers and Others at Increased Risk of SARS-CoV-2 Infection

Emergence of Covid-19 virus is associated with high frequency of extremely severe clinical pictures, with minor signs of CNS impairment (e.g. anosmia, headache). Since neurotropism is a common feature of coronavirus infection in animals, the investigators examine if indirect signs of CNS lesion are observed in association with severe Covid-19 infection.
