Brief Summary: Purpose of this study is to evaluate efficacy of hydroxychloroquine (HCQ) in reducing progression of Corona Virus Disease 2019 (COVID - 19) and achieving viral clearance.
Condition or disease :I COVID-19 ntervention/treatment :Drug: Hydroxychloroquine Sulfate Phase: Phase III
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Covid19 Progression | Drug: HCQ | Phase 3 |
This study explores efficacy of HCQ (400mg BD on D0 and 200mg BD D1-D5) in reducing progression of Mild Covid-19 patients and decreasing viral load.
Participants of study will be randomized 2:1 to receive either Active drug or standard of care (SOC) treatment respectively. We aim to demonstrate reduced COVID-19 progression and early viral clearance in individuals on HCQ therapy.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 540 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Randomization rules were designed by Dr. Wasim Alamgir together with principal investigators and implemented by an independent statistician who was not involved in data analysis. Stratified random sampling was applied to stratify all eligible patients according to age, gender and comorbidities. Computerized random number generator was used and allocation was done in 2:1 sequence. Cards with each group assignment number randomly generated by computer were placed in sequentially numbered envelopes that were opened as the patients were enrolled |
Masking: | None (Open Label) |
Masking Description: | Neither patients, nor investigators, nor statisticians were masked to treatment assignment. Lab staff who performed sampling for PCR, basic blood tests and other routine measurement were unaware of treatment information. |
Primary Purpose: | Treatment |

Arm | Intervention/treatment |
---|---|
No Intervention: Standard of Care (SOC)
Patients selected in supportive arm will be given daily standard doses of oral Vit C (2g), Vit D (alfacalcidiol 1µg), Zinc (50mg) and paracetamol (as required).

Experimental: HCQ arm
Patients selected in experimental arm will be given Tab HCQ (400mg BD on D0 followed by 200mg BD D1-D5) in addition to supportive treatment

Drug: HCQ
Tab HCQ 400mg 12 hourly day 0 followed by tab HCQ 200mg 12 hrly for next 5 days
Other Name: HCQ + Standard of Care (SOC) |
- Number of Participants With Progression [ Time Frame: 5 days ]After start of treatment, development of fever > 101 F for > 72 hours, shortness of breath by minimal exertion (10-Step walk test), derangement of basic lab parameters (ALC < 1000 or raised CRP) or appearance of infiltrates on CXR during course of treatment was labeled as progression irrespective of PCR status
- Viral Clearance [ Time Frame: 14 days ]PCR negativity on day 7 and 14 after admission
