About this study

Official title: Safety And Efficacy Of Hydroxychloroquine For At Risk Population (SHARP) Against COVID-19- A Cluster Randomized Controlled Trial (SHARP COVID-19 RCT)

The Coronavirus Disease 2019 (COVID-19) pandemic has placed tremendous stress on the global economy since its outbreak in December 2019. Currently, with nearly 1.3 million confirmed cases, there is still no effective way to contain the disease. The transmission of COVID-19 occurs via direct (prolonged close interaction, within 2 meters for more than 30 minutes) and indirect (fomites) contacts. Locally, the risk of COVID-19 infection in household contacts of confirmed cases is about 4%. These at-risk individuals are identified through contact tracing and infectious may be preventable using post-exposure-prophylaxis (PEP). However, there has yet to be a single effective, safe, and affordable pharmacological agent with such capabilities. Hydroxychloroquine (HCQ) is a cheap anti-malarial and immunomodulatory agent which may potentially be used as PEP against COVID-19. HCQ is capable of blocking the invasion and intracellular replication of the virus. Existing studies have reported efficacy of HCQ in treating COVID-19, with reduced time to clinical recovery and few reports of patients suffering from significant side effects. However, existing studies are largely limited by their small sample sizes. Furthermore, there has yet to be a published trial on HCQ's role in PEP. This cluster randomized trial will evaluate the safety and efficacy of oral HCQ PEP, taken over for 5 days, in reducing the number of infected household contacts of confirmed COVID-19 patients under home quarantine. Comparison will be made between HCQ PEP (treatment group) and no treatment (control group). Subjects will be followed up over a course of 28 days, with daily symptom monitoring conducted over phone calls. Positive outcomes from this study will provide a means for us to battle the COVID-19 pandemic.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. positive serology or reverse transcriptase (RT-PCR) for COVID-19 up until day 28.

    COVID-19 infection

    Measured: Until day 28

Secondary outcomes (2)
  1. Positive serology at day 28.

    Serology

    Measured: 28 days

  2. Symptoms of COVID-19.

    COVID-19

    Measured: Until day 28

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted10 Apr 2020
  2. Study startApr 2020 (estimated)
  3. Primary completionAug 2020 (estimated)
  4. Study completionOct 2020 (estimated)

Why it stopped: The number of patients with COVID-19 in Singapore was coming down for the community and the concerns about the potential side effects particularly when the baseline ECG and serum electrolytes was not proposed.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hydroxychloroquine Sulfate 200 milligram (mg) Tab in people with Coronavirus Infection and Hydroxychloroquine Adverse Reaction, run by Tan Tock Seng Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 8 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

positive serology or reverse transcriptase (RT-PCR) for COVID-19 up until day 28. (time frame: Until day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2020.
