Phase 2 vs 3 vs 4 2 arm study vs 4 arm study Dose-based (200 vs 400 vs 600 mg) Frequenc-based ( Once vs twice vs trice per day) Duration-based (5 vs 10 vs 14 ... days)

Hydroxychloroquine

Country	Intervention	Objective	Design&Date	Strategy	Outcome
Renmin Hospital of Wuhan University, China	Hydroxychloroquine (HCQ) (Preprint article)	Treatment efficacy evaluation	February 4 to February 28, 2020 62 patients with confirmed COVID-19 diagnosis Participants were randomized in a parallel-group trial Males: 46.8%; Female: 53.2%; Mean age: 44.7 years. age and sex were adjusted between the control group and the HCQ group 31 patients treatment group	A 5-day HCQ (400 mg/d) treatment The HCQ effect was evaluated at baseline and 5 days after treatment by assessing the following: Time to clinical recovery (TTCR), clinical characteristics, and radiological results	TTCR, the body temperature recovery time and the cough remission time were significantly shortened in the HCQ treatment group (80.6%, 25 of 31of patients with improved pneumonia in the HCQ treatment group compared with the control group (54.8%, 17 of 31) 4 patients progressed to severe illness that occurred in the control group 2 patients with mild adverse reactions in the HCQ treatment group Conclusion: The use of HCQ could significantly shorten TTCR and promote the absorption of pneumonia in patients with COVID-19
Méditerranée Infection University Hospital Institute in Marseille, France	Hydroxychloroquine and azithromycin	Treatment efficacy evaluation	Early March to March 16th 36 out of 42 patients meeting the inclusion criteria 6 lost to follow up 20 hydroxychloroquine-treated patients 16 control patients Patients were included in a single-arm protocol Inclusion criteria: Age >12 years PCR documented SARS-CoV-2 carriage in nasopharyngeal sample at admission regardless of the clinical status Control was untreated patients from another center and cases refusing the protocol Endpoint: presence and absence of virus at Day6-post inclusion	600mg of HCQ daily 200 mg, three times per day for ten days Viral load in nasopharyngeal swabs was tested daily in a hospital setting Azithromycin: Added depending on the clinical presentation 500mg on day1 followed by 250mg per day, the next four days To prevent bacterial super-infection under daily electrocardiogram control	There was a statistically significant difference between treated patients and controls at days 3-4-5 and 6 (negative PCR) At day 6, 70% of HCQ-treated patients were virologically cured comparing with 12.5% in the control group (p= 0.001) HCQ vs HCQ-Azithromycin combination There was a statistically significant difference between treated patients and controls at days 3-4-5 and 6 (negative PCR) At day 6, 100% of patients treated with HCQ and azithromycin combination were virologically cured comparing with 57.1% in patients treated with HCQ only, and 12.5% in the control group (p < 0.001) Conclusion: HCQ is significantly associated with viral load reduction/disappearance in COVID-19 patients and its effect is reinforced by azithromycin
Marqués de Valdecilla University Hospital, Cantabria, Spain	HDQ	Chemoprophylaxis	Start scheduled for the second week of May 2020 Prospective, single center, double blind, randomised, controlled trial (RCT) 450 Adult health-care professionals (18-65 years) Working in areas of high exposure and high risk of transmission of SARS-COV-2	Oral Hydroxychloroquine 200mg, once-daily, for two months (HC group) or placebo (P group) Intervention: (n = 225): One 200 mg hydroxychloroquine sulfate coated tablet once daily for two months. Comparator (control group) (n = 225): One hydroxychloroquine placebo tablet (identical to that of the drug) once daily for two months In addition to the protective measures appropriate to the level of exposure established by the hospital. A serological evaluation every 15 days with PCR in case of seroconversion, symptoms or risk exposure.
Eight hospitals in Spain	Melatonin	Prophylaxis	Recruitement (May 21-31) 450 participants 225 in the experimental arm 225 in the placebo arm.	Experimental: Melatonin (Circadin®, 2 mg of melatonin orally before bedtime for 12 weeks. Comparator: Identical looking placebo, orally before bedtime for 12 weeks.
