What is being measured

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

  1. Viral load

    Change from baseline in viral load of SARS-CoV-2 in throat swabs by RT-PCR on Day 6 (after last dose)

    Measured: Baseline through Day6

  2. Time to Sustained Alleviation

    Time to Sustained Alleviation of 5 COVID-19 signs/symptoms

    Measured: Baseline through Day28

Secondary outcomes (5)
  1. Viral load

    Changes of viral load compared to the baseline

    Measured: Baseline through Day28

  2. Time to Sustained Alleviation

    Time to Sustained Alleviation of target COVID-19 signs/symptoms

    Measured: Baseline through Day28

  3. Proportion of participants progress to a worsening status(higher score)

    WHO clinical progress scale(0 to 10)

    Measured: Baseline through Day28

  4. Adverse events

    Frequency of TEAE

    Measured: Baseline through Day28

  5. Maximum plasma concentration(Cmax)

    Plasma concentration of SSD8432

    Measured: Baseline through Day5

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing SSD8432 750mg in people with COVID-19, run by Jiangsu Simcere Pharmaceutical Co., Ltd..

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 7 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 24 May 2022. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Results are not available in the source record.

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

Contact Genqiang An (86-13520683611, angenqiang@simcere.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Viral load (time frame: Baseline through Day6). The study lists 2 primary outcomes in all. 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 24 May 2022.
