This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

Researchers are testing whether an antiviral tablet called S-217622 can prevent symptomatic COVID-19 in people who live with someone who has symptoms. The trial enrolls household contacts of a person with symptomatic COVID-19 and gives them either the antiviral or a placebo for a short period. The main goal is to see how many people in each group test positive for SARS-CoV-2 and develop COVID-19 symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
S-217622, an experimental antiviral tablet
What this could lead to
If it works, people exposed to COVID-19 at home could take a short course of tablets to avoid getting sick, similar to how Tamiflu is used for flu.
What could go wrong
The antiviral may not prevent enough infections to be useful, or it may only work against certain variants. Like any drug, it can cause side effects, and a phase 3 trial is needed to know if benefits outweigh risks.

Inclusion Criteria: Index Participants Only 1 index participant from each household will be enrolled in the study. Participants are eligible to be included as an index participant if all of the following criteria apply: 1. Pediatric participants or adult participants (of any age) 2. The index participant must: 1. Have at least 1 COVID-19 symptom within 24 hours before the index participant providing informed consent. COVID-19 symptom(s) must be deemed by the investigator as related to the current SARS-CoV-2 infection (not related to preexisting comorbidities) or deemed as preexisting and worsened due to SARS-CoV-2 infection. 2. Must have positive SARS-CoV-2 test (a nucleic acid amplification test or antigen test) from any respiratory tract specimen from a sample collected prior to randomization of the participant 3. Must have a potential study participant who can participate in the study after onset of COVID-19 symptoms in an index participant Study Participants Multiple study participants from the same household are allowed to be enrolled in the study. The study intervention randomization will be performed based at the study participant's level. Participants will be eligible to be included in the study only if all of the following criteria apply: 1. ≥ 12 years of age at the time of signing the informed consent 2. Has a negative screening for SARS-CoV-2 infection, as determined by SARS-CoV-2 test (a nucleic acid amplification test or antigen test) from any respiratory tract specimen (for example, oropharyngeal, nasopharyngeal or nasal swab, or saliva). 3. Has lived in household with index participant and will continue to live in same household and share common areas such as dining rooms and bathrooms until the end of the study 4. Must not be considered by the investigator or subinvestigator to have SARS-CoV-2 infection and: 1. No measured fever at Screening (defined as body temperature ≥ 38.0°Celsius \[C\] per tympanic or rectal thermometer or ≥ 37.5°C per axillary, oral, or forehead/temporal thermometer) 2. No COVID-19 symptoms at Screening (if a participant has COVID-19-like symptoms caused by comorbidities, only 1 symptom will be allowed) 5. Capable and willing to complete a participant diary 6. a. Male participants: Participants with partners that are woman of childbearing potential (WOCBP) must agree to use effective contraception. Participants with pregnant partners must agree to use effective contraception. b. Female participants: A female participant is eligible to participate if she is not pregnant or breastfeeding, and the following conditions applies: * Is not a WOCBP or * All of the following apply: * Is a WOCBP and using a contraceptive method that is effective as described in the protocol. * A WOCBP must have a negative urine pregnancy test within 24 hours before the first dose of study intervention period. * If a urine pregnancy test cannot be confirmed as negative (for example, an ambiguous result), a serum pregnancy test must be negative. * Additional requirements for pregnancy testing during and after study intervention as described in the protocol. * The investigator/subinvestigator will review medical history, menstrual history, and recent sexual activity to decrease the risk of inclusion of a woman with an early undetected pregnancy. 7. Participant must be randomized ≤ 72 hours from onset of COVID-19 symptoms in the index participant. Exclusion Criteria: Study Participants: Participants will be excluded from the study if any of the following criteria apply: 1. Tested positive for SARS-CoV-2 in the past 6 months. 2. Have an underlying disease requiring systemic corticosteroids (excluding topical), antipyretics/analgesics, or immunosuppressive agents. 3. Known current renal impairment defined as creatinine clearance \< 30 milliliters/minute by Cockcroft Gault or requiring dialysis. 4. Participants with severe liver dysfunction, such as known history of cirrhosis or liver decompensation (including ascites, variceal bleeding, or hepatic encephalopathy). 5. Received approved, authorized, or investigational convalescent plasma, or other anti- SARS-CoV-2 biologic products within 3 months of the Screening Visit 6. Received approved, authorized, or investigational anti-SARS-CoV-2 monoclonal antibodies (mAbs) in the last 6 months. 7. Received any SARS-CoV-2 vaccine within 6 months prior to the Screening Visit or is expected to receive a SARS-CoV-2 vaccine or other approved, authorized, or investigational postexposure prophylaxis treatments until the end of the study. 8. Participants who have used any of the following drugs within 14 days prior to enrollment: 1. Strong cytochrome P450 (CYP) 3A inducer 2. Products containing St. John's wort 9.
