COVID-19 Clinical Trials and Expanded Access

The search for novel therapies to address the ongoing coronavirus (COVID-19) pandemic is ongoing. No proven therapies have been identified to prevent progression of the virus. Preliminary data suggest that inhaled nitric oxide (iNO) could have benefit in preventing viral progression and reducing reliance on supplemental oxygen and ventilator support. Expanded access allows for iNO to be delivered via the portable INOpulse delivery system for the treatment of COVID-19.

The purpose of this study is to find out if estrogen, a female sex hormone, given as a patch placed on skin of COVID19 positive or presumptive positive patients for 7 days can reduce the severity of COVID19 symptoms compared to regular care. This study has two study groups. One group will receive the study drug, a single-use Climara 25cm2 estrogen patch. The other group will receive standard of care. Participants will be asked questions about their symptoms for up 6 times in up to 45 days.

The performance of 3 different sampling methods (2 nasopharyngeal swabs, 1 oropharyngeal swab) for the detection of SARS-CoV-2 with real-time reverse transcriptase polymerase chain reaction will be compared.

In this study, investigators will determine whether the early addition of HT-CCP to standard treatment improves the clinical outcome (as assessed by the Modified WHO Ordinal Scale) of patients with COVID-19 who are hospitalized but not yet in moderate or severe ARDS.

It is a multicenter, national, randomized 1:1 ratio, controlled, parallel, open study. Patients with severe ARDS-CoVid19 will be included in the trial within the first 24 hours. Patients will be randomized to one of the treatment groups: - SEV group: 25 patients with Sevoflurane sedation by inhalation, starting at 6 ml/h and changing every 15 minutes until an adequate level of sedation is achieved (BIS 40-50) - PRO group: 25 patients standard sedation with intravenous propofol, starting with 2 mg/kg/h and changing every 15 minutes until an adequate level of sedation is achieved ( BIS 40-50)

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.

I. Study Design: This is a single-arm feasibility study to assess the safety and efficacy of anti-SARS-CoV-2 convalescent plasma (CP) in 1. intubated, mechanically ventilated patients with confirmed COVID-19 pneumonia by chest X-ray or chest CT. 2. hospitalized patients with acute respiratory symptoms between 3 and 7 days after the onset of symptoms, with COVID-19. II. Study Population: 1. Population 1: Mechanically ventilated intubated COVID-19 patients aged 18 years or older. 2. Population 2: Hospitalized COVID-19 patients aged ≥18 years of age with respiratory symptoms within 3 to 7 days from the beginning of illness. III. Study Agent: SARS-CoV-2 convalescent plasma (1-2 units; ~200-400 mL at neutralization antibody titer >1:160.

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.
