Interacts with people at least twice a week without a mask (e.g., grocery shopping, dinner with grandchildren, eating at a restaurant, going to the movies, etc.) or are living in a multigenerational home.

Inclusion criteria

to be assessed only at Randomization:

If on stable COPD maintenance therapy this should be stable for at least 2 months prior to randomization. Changes allowed with Sponsor approval (i.e., change within same class due to financial considerations and clinically stable).

Clinically stable with no other exacerbations or respiratory infections (viral or bacterial) within 2 months prior to randomization.

The presence of RV (without a co-infection) at the time of randomization based on an approved molecular diagnostic test.

To be randomized, participants must have at least 3 E-RS scores completed within the previous 35 days to establish a PSB.

Exclusion

Pregnant or nursing or expected to become pregnant during the study period. Experiencing a current/active or prior exacerbation within 2 months of the Screening Visit (these participants should be rescreened after the exacerbation has been resolved for two months).

Participants with other primary causes of chronic airflow limitation:

  • Including but not limited to: asthma alone (COPD with asthmatic features is acceptable), CF, bronchiolitis obliterans, fibrosis such as TB, IPF, non-CF bronchiectasis with multi-lobe involvement or other major respiratory diagnosis (e.g., allergic bronchopulmonary aspergillosis), etc.

Any disorder, for example, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, hematological, psychiatric impairment that is not medically stable, or other major physical impairment that is not considered by the investigator medically stable/controlled.

Participants with hepatitis B are excluded. Participants on a stable treatment for HIV can be permitted with permission from the medical monitor. Participants with hepatitis C should be treated and confirmed HCV RNA negative prior to enrollment. (Testing performed at the Screening Visit).

In the Investigator's opinion, the participant has any clinically significant laboratory abnormality including an abnormality that indicates clinically significant hematologic, hepatobiliary, or renal disease.

Presence of clinically significant out-of-range cardiac interval on the screening ECG including a QTcF > 450 msec (men) and a QTcF > 460 msec (women).

Medications that are potent CYP2C8, CYP3A4 or CYP2C19 inducers that would reduce exposures of VPV.

Medications that are potent CYP2C8, CYP3A4, or CYP2C19 inhibitors that would increase exposures of VPV.

Medications that are substrates of MATE1, OAT3, P-gp, and BCRP for which elevated concentrations are associated with serious and/or life-threatening reactions.

Use of either of the following treatments:

  • Chronic oral/systemic steroids >10 mg per day (inhaled corticosteroids are permitted).
  • Continuous oxygen via nasal cannula of >2 L/min at the time of Screening or during the Asymptomatic Phase. (Participants on continuous oxygen may have the rate increased during physical exercise/ exertion or to cover any situationally induced decompensation, so long as the participant will resume a continuous rate of ≤2 L/min thereafter).

Participation in another investigational drug study within 5 half-lives prior to Screening and during the study is prohibited. This includes approved drugs being evaluated for a new indication. Observational studies are permitted.

Participants who have taken VPV in another clinical trial.

Exclusion criteria

to be assessed only at Randomization:

Primary outcomes

  1. Evaluating Respiratory Symptoms (E-RS)

    Time frame: Baseline Period/Asymptomatic Phase: Daily for 12 weeks Treatment/Follow-Up Periods: Daily for up to 42 days

    11-item E RS collected as part of the 14-item EXAcerbations of Chronic pulmonary disease Tool (EXACT PRO®) scale, with data from the additional 3 items from the EXACT PRO scale used for exploratory purposes only. The PSB will be calculated as the mean of the E-RS scores collected in the -35 to -6 days prior to RV symptom onset. If the E-RS score has not returned to PSB at the time of Day 28 Visit, the participant will complete the E-RS daily until Day 42. The questions are asked about how the participant feels today and will be collected at night.

Secondary outcomes

  1. Patient Global Impression of Severity (PGIS)

    Time frame: Baseline Period/Asymptomatic Phase: Daily for 12 weeks Treatment/Follow-Up Periods: Daily for up to 42 days

    The PGIS is one question, 'Please rate the overall severity of your respiratory symptoms today? (none, mild, moderate, severe, very severe).'

  2. Wisconsin Upper Respiratory Symptom Survey - 11

    Time frame: Treatment/Follow-up Periods: Daily for 28 days

    The questions are asked about how the participant feels today or within the last 24 hours. The questionnaire will be completed at night.
