Two recent studies have suggested that in patients with Covid19, treatment with hydroxychloroquine may shorten the duration of symptoms and improve viral clearance, an effect that appears most pronounce when combined with azithromycin. Hydroxychloroquine treatment may inhibit viral nucleic acid-mediated activation of various innate immune pathways, as well as blockade of lysosomal functions in cell types relevant for viral entry and antigen presentation. The purpose of the study is to determine if oral hydroxychloroquine monotherapy, or in combination with azithromycin results in clinical benefit in patients hospitalized with COVID19 pneumonia.

Novel corona virus (SARS-CoV-2) epidemic which stared from Wuhan in China is now a well established pandemic worldwide. After Italy, Spain, Germany, United Kingdom and USA, India is at the edge of becoming the next epicentre of this Pandemic. If adequate preventive and therapeutic measures are not taken, India has very high risk of affecting million of people with high mortality because of the large population along with very high population density. At present there are no definitive therapeutic drugs or vaccine are available for the treatment and prevention of SARS-CoV-2 infection. Symptomatic and supportive care are being given to COVID-19 cases along with isolation and quarantine measure are being taken for the suspected individual at risk for COVID-19 to limit the spread of the SARS-CoV-2 infection . Among the all the drugs being used for the treatment of COVID-19, hydroxychloroquine (HCQ), has given some rays of hope to battle against this deadly pandemic. HCQ has some anti viral effect against SARS-CoV in vitro. HCQ is quite safe and being used in rheumatology patients for lifelong without much side effect, so it allow for higher dose without any significant side effects and drug-drug interaction. Recently published clinical trial suggested HCQ can be used for the therapeutic purpose of the SARS-CoV-2 infection. Indian council of medical research (ICMR) has advised for HCQ prophylaxis for all asymptomatic health care workers involved in taking care of suspected or confirmed COVID-19 cases and all asymptomatic household contacts of labarotory confirmed COVID-19 cases. But there is still lack of significant scientific data to prove or disprove the efficacy of HCQ for the treatment and post exposure chemo-prophylaxis for SARS-CoV-2 infection. Being a tertiary care centre we are catering many states which include Punjab, hariyana, himachal Pradesh, Uttara khand, Uttar Pradesh. Among this Punjab have highest population of non residential Indian (NRI) and most of them have returned home. This put our institute to handle highest burden of suspected cases of SARS-CoV-2 in northern India. So we have planned this open level control clinical trial to evaluate the efficacy of post exposure prophylaxis (PEP) with HCQ for the prevention of COVID-19 in asymptomatic individuals who are at risk for SARS-CoV-2 infection. All asymptomatic individuals who have undertaken international travel in last 2 weeks and all asymptomatic individual with direct contact with laboratory confirmed cases will be advised for home quarantine for 2 weeks along with social distancing and personal hygiene. They will be given the option for taking HCQ prophylaxis. These quarantined asymptomatic individuals will be assigned into one post exposure prophylaxis (PEP) group and one control group as per inclusion and exclusion criteria. Individual who will not give consent for HCQ prophylaxis and those with contraindication for HCQ therapy like, hypersensitivity to HCQ or 4-aminoquinolone derivatives, patients with known retionopathy, cardiac arrhythmia, G6PD deficiency, psoriasis and pregnancy will be directly included in the control group. All symptomatic individual, and all health care workers related to suspected or proven COVID-19 will be excluded from the study. The PEP group will receive tablet HCQ 400 mg q 12 hourly on day one followed by 400 mg once weekly for 3 weeks (total cumulative dose of 2000 mg). The control group will not receive HCQ. Both the groups will receive standard care of therapy in the form of home quarantine for 2 weeks along with social distancing and personal hygiene. They will be followed up for 4 weeks telephonically or physically as and when required and will be enquired regarding development of any COVID-19 symptoms like fever, cough, sore throat, shortness of breath, diarrhoea, myalgia.During follow up nasopharyngeal and or throat swab of the participants will be taken for processing reverse transcription polymerase chain reaction (RTPCR) for the detection SARS-Cov-2 RNA to confirm CoVID-19. Samples for RTPCR will be taken when any asymptomatic participants become symptomatic and by the 5-14 days of contact in asymptomatic participants through in-hospital visit at the institute's communicable disease ward isolation. The participant with RTPCR positive and with or without symptoms will be defined as definite COVID-19 case and the RTPCR negative symptomatic participant will be defined as probable COVID-19 case. Asymptomatic participants with negative RTPCR will be defined as non-COVID case. Incidence of COVID-19 or probable COVID-19 or non-COVID case in previously asymptomatic participants will be compared between the PEP and control groups.
