About this study

Official title: A Multicenter, Randomized, Double Blind, Placebo-Controlled, Phase 3 Study to Determine if RTB101 Prevents Clinically Symptomatic Respiratory Illness in the Elderly

The purpose of this study is to determine if RTB101 prevents illness associated with respiratory tract infections in people ≥65 years of age.

Read the detailed description

RTB-101-205 is a randomized, double-blind, placebo-controlled, multicenter, parallel-group, Phase 3 study to determine if RTB101, a selective TORC1 inhibitor, prevents illness associated with respiratory tract infections (defined as clinically symptomatic respiratory illness) in adults ≥65 years of age. This trial is being conducted in follow up to two Phase 2 trials in older adults in which RTB101 10 mg administered once daily for up to 16 weeks during winter cold and flu season was observed to reduce the incidence of respiratory illness associated with respiratory tract infections.

Being tested

What is being measured

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

  1. Percentage of subjects with clinically symptomatic respiratory illness

    Measured: Through Week 16

Secondary outcomes (7)
  1. Percentage of subjects with clinically symptomatic respiratory illness associated with ≥1 laboratory-confirmed pathogen(s)

    Measured: Through Week 16

  2. Rate of clinically symptomatic respiratory illness (with or without an associated laboratory-confirmed pathogen)

    Measured: Through Week 16

  3. Rate of clinically symptomatic respiratory illnesses associated with ≥1 laboratory-confirmed pathogen(s)

    Measured: Through Week 16

  4. Time to alleviation of moderate and severe respiratory illness symptoms due to clinically symptomatic respiratory illness

    Measured: Through Week 16

  5. Percentage of subjects with severe respiratory illness symptoms due to clinically symptomatic respiratory illnesses

    Measured: Through Week 16

  6. Number of participants with treatment-emergent adverse events as assessed by CTCAE v5.0

    Measured: Through Week 20

  7. Rate of clinically symptomatic respiratory illnesses associated with specific laboratory-confirmed viruses

    Descriptive statistics will be provided for the rate of clinically symptomatic respiratory illnesses associated with specific laboratory-confirmed viruses. No formal statistical tests will be conducted.

    Measured: Through Week 16

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dactolisib in people with Clinically Symptomatic Respiratory Illness, run by Restorbio Inc..

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 3 inclusion and 8 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 22 Nov 2019. 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 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?

Percentage of subjects with clinically symptomatic respiratory illness (time frame: Through Week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04139915, which also lists 1 linked publication.

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 22 Nov 2019.
