NCT05438602

Do you or your child have symptomatic COVID-19? A clinical trial may be an option.

The FDA has granted Emergency Use Authorization for a 5-day course of PAXLOVID™ (nirmatrelvir/ritonavir) to treat COVID-19 in people at least 12 years of age with mild-to-moderate COVID-19 who are at risk of developing severe illness. However, people with weakened immune systems or other risk factors are more likely to have prolonged or treatment-resistant COVID-19.

This study is evaluating if a longer course of PAXLOVID™ may be beneficial for adults and adolescents with symptomatic COVID-19 who are immunocompromised.

Card Summary Component

Condition

COVID-19

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Age

12+ years

The age a person must be to participate in a clinical trial.

Sex

Male or Female

The sex of people who may participate in a clinical trial. Sex is a person’s classification based on assignment at birth. Eligibility based on sex is distinct from eligibility based on gender.

Each clinical study has its own guidelines for who can participate, called eligibility criteria. However, only the research study staff can determine if you qualify to enroll in the study.

What to expect

If you or your child is interested in participating, the study team will schedule a screening visit to determine if you/he/she can join the study.  

You or your child will be randomly assigned to receive the study drug PAXLOVID™ for 5, 10, or 15 days:

  • Group 1: 5 days PAXLOVID, 10 days placebo (no active ingredient)
  • Group 2: 10 days PAXLOVID, 5 days placebo (no active ingredient)
  • Group 3: 15 days PAXLOVID, 0 days placebo (no active ingredient)

All participants will take PAXLOVID™, and placebo (in case they are enrolled in groups 1 or 2), by mouth twice daily for 15 or 16 days, for a total of 30 doses. 

You or your child will be enrolled in the study for about 6 months and will need to attend at least 10 study visits during this time. These visits will be completed in clinic. If in-clinic visits are not feasible, alternate locations may be allowed. 

Length of study treatment

15 or 16 days (30 total doses)

Length of study treatment is the length of time the study participants will receive the study treatment.

Number of study visits

At least 10

Each clinical trial’s design specifies the number of study visits and the total length of the trial.

Long-term follow up

3-month and 6-month follow-up visits

Some studies require the study team to stay in contact with the participant for a period of time after the participant completes the main part of the study. This long-term follow up is to collect additional information on the study drug over time.

About the study medicine

PAXLOVID™ is a combination of the medicines nirmatrelvir and ritonavir. PAXLOVID™ was studied in a previous clinical trial of non-hospitalized adults with symptomatic COVID-19 who had at least 1 risk factor for progressing to severe COVID-19. The results from that study showed that participants who received PAXLOVID™ were less likely to be hospitalized or die from COVID-19 compared to participants who received a placebo.

PAXLOVID™ has not been approved, but has been authorized for emergency use by FDA under an EUA, for the treatment of mild-to-moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death.

The emergency use of PAXLOVID™ is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization revoked sooner.
