Brief Summary

Protocol summary Title A Prospective, randomized, adaptive phase II/III clinical trial, controlled, open-label, chemoprevention, 3-arms, parallel, multi-centred, to A Prospective, randomized, clinical trial, controlled, open-label, 3-arms, parallel, multi-centred, chemoprevention of COVID-19: Hydroxychloroquine Post Exposure Prophylaxis For COVID-19 Study Periods \& Duration of Treatment Study Duration: 6 months Approval (IRB and regulatory bodies) 1 month Recruitment and follow-up: 3 months Analysis, report writing and submission of publications 1 month This study is a parallel study of one period with an expected duration of treatment (for each subject) of 28 days, Objectives

  • To evaluate if hydroxychloroquine with the proposed dose can provide potent chemoprophylaxis against the development of COVID-19 positive patients in subjects who had primary exposure to COVID-19 positive patients.
  • To measure the incidence of potential adverse drug reaction rates for giving hydroxychloroquine for prevention of COVID-19 amongst close contacts
  • To provide early analysis of results and redefine sample size accordingly.
  • identifying subjects most likely to benefit during the phase II and focusing recruitment efforts on them during phase III
  • stopping one arm or the whole trial at an early stage for success or lack of efficacy based on phase II study results Design Prospective, Randomized, open-label, three-arm, parallel, adaptive phase II/III controlled study in which subjects will be randomly assigned in a 1:1:1 ratio as per the following: Arm-1: hydroxychloroquine 800mg (400mg twice daily) given orally on day 1, (loading dose) hydroxychloroquine. Then 400mg (200mg 2 tablets) on day 2,3, 4 and 5. Arm-2: hydroxychloroquine 400mg (200mg twice daily) Given orally first day (loading dose), then 200mg once daily on day 2,3, 4 and 5. Arm-3: No Intervention- SARS-CoV-2 surveillance Standard control measures in the country of interest such as self isolation, good personal hygiene and good nutrition.

Outcome Measures

Primary Outcomes (2)

  • Incidence rate of COVID-19 on day 14 according to positive results of RT-PCR rate at day 14

    Study will seek to find direct correlation between the administration of Hydroxychloroquine and incidence of COVID-19: A reduced positive RT-PCR samples in subjects who were exposed to COVID-19patients. Positive RT-PCR samples in close contacts on day 14 of randomization.

    14 days

  • Safety and adverse events (AEs) incidence rate at day 14

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Primary contacts, described below, aged 18 to 65 years and having provide Written informed consent by the patient, by the patient's legal /authorized representative as applicable.
  • According to below criteria, as soon as a new subject in identified, he/she will be consented for reaching his contacts according to below criteria. The research team within 48 hours of index case identification will call his/her contacts who fulfill below criteria for participation in the trial. All potential participants will be tested using RT-PCR and IgM and IgG antibodies to rule out current or previous disease status.
  • Contact is a person free from COVID-19 who experienced any one of the following exposures during the 2 days before and the 14 days after the onset of symptoms of a probable or confirmed case:
