About this study

Official title: A Randomized, Double-blind, Placebo-controlled, 2-Part Study of Orally Administered AK0529 to Evaluate the Safety, Tolerability, Pharmacokinetics and Antiviral Effect of Single and Multiple Dosing in Hospitalized Infants With Respiratory Syncytial Virus Infection

VICTOR is a randomized, double-blind, placebo-controlled, multicenter, 2-part study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and antiviral effect of single and multiple dosing of AK0529 in infants hospitalized with RSV infection.

Read the detailed description

Globally, Respiratory Syncytial Virus (RSV) is recognized as the leading cause of respiratory tract infections in infants and young children and a major cause of hospitalization due to severe respiratory infection. Despite four decades of effort, there are still no effective methods to control RSV infection. Treatment of RSV has been limited to supportive measures. There is an urgent need for safe and effective drugs to treat and prevent RSV disease.

AK0529 is an investigational antiviral agent that targets the RSV fusion protein on the surface of the viral envelope and exerts antiviral activity against RSV by inhibiting viral entry into host cells and preventing fusion protein induced cell-cell fusion. AK0529 was generally well tolerated in healthy volunteers.

This study is designed as a randomized, double-blind, placebo-controlled, multicenter, phase 2 study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and antiviral effect of single and multiple dosing of AK0529 in infants hospitalized with RSV infection. It will consist of two parts, Part 1 and Part 2. Each part will consist of three phases, a pre-treatment phase, a treatment phase and post-treatment follow-up phase.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AK0529Drug

    AK0529 is a novel compound being developed for the treatment of RSV infection. The enteric coated drug pellets with sugar core can be administered orally with apple sauce/purée or yoghurt, or by flushing with 10% dextrose water via a nasogastric or other feeding tube, or upon a glucose wafer.

  • PlaceboDrug

    The placebo was made with the same smell and appearance as AK0529 but without the active ingredients. The placebo supplements are composed primarily of microcrystaline cellulose pellet.

What is being measured

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

  1. Incidence of Adverse Events during the study

    Measured: Day -4 to single dose Day 7 (Part 1) and Day -3 to multiple dose Day 14 (Part 2)

  2. Subject withdrawals due to Adverse Events

    Measured: Day -4 to single dose Day 7 (Part 1) and Day -3 to multiple dose Day 14 (Part 2)

Secondary outcomes (8)
  1. Area under the plasma concentration-time curve from time 0 to infinity (AUC)

    For patients without intravenous cannulation, samples will be collected at pre-dose, 2, 6 and 12 hours post-dose on Day 1.

    Measured: Pharmacokinetic samples will be taken predose, 2, 4, 6, 12, 18, 24 hours postdose on Day 1, 48 hours postdose (Part 1 and Part 2) and Day 5 (Part 2 )

  2. Maximum plasma concentration of AK0529 (Cmax)

    For patients without intravenous cannulation, samples will be collected at pre-dose, 2, 6 and 12 hours post-dose on Day 1.

    Measured: Pharmacokinetic samples will be taken predose, 2, 4, 6, 12, 18, 24 hours postdose on Day 1, 48 hours postdose (Part 1 and Part 2) and Day 5 (Part 2 )

  3. Plasma concentration of AK0529 at 12 hours postdose (C12)

    For patients without intravenous cannulation, samples will be collected at pre-dose, 2, 6 and 12 hours post-dose on Day 1.

    Measured: Pharmacokinetic samples will be taken predose, 2, 4, 6, 12, 18, 24 hours postdose on Day 1, 48 hours postdose (Part 1 and Part 2) and Day 5 (Part 2 )

  4. Apparent total body clearance (CL/F)

    For patients without intravenous cannulation, samples will be collected at pre-dose, 2, 6 and 12 hours post-dose on Day 1.

    Measured: Pharmacokinetic samples will be taken predose, 2, 4, 6, 12, 18, 24 hours postdose on Day 1, 48 hours postdose (Part 1 and Part 2) and Day 5 (Part 2 )

  5. Apparent central compartment volume of distribution (Vc/F)

    For patients without intravenous cannulation, samples will be collected at pre-dose, 2, 6 and 12 hours post-dose on Day 1.

    Measured: Pharmacokinetic samples will be taken predose, 2, 4, 6, 12, 18, 24 hours postdose on Day 1, 48 hours postdose (Part 1 and Part 2) and Day 5 (Part 2 )

  6. Area under curve change of viral load

    The antiviral effects in infants hospitalized with RSV are to be determined by measuring the RSV viral load area under the curve in nasal, pharyngeal and tracheal washes / aspirates from baseline to last administration of study medication (Day 5).

    Measured: From baseline to Day 5

  7. Incidence of F-protein genotypes

    The incidence of F-protein genotypes associated with reduced sensitivity to IMP will be evaluated.

    Measured: Specimen will be collected predose and 24 hours postdose on Day 1 (Part 1) and on Day 1-5 (Part 2).

  8. Change of symptom score

    To evaluate the change of RSV related symptom score in AK0529 arms compared with the change in placebo arm after treatment. The total score is reported with a range from 0 to 12. A decreasing value of total score represents clinical improvement. Subscales are not applicable in this symptom score.

    Measured: From baseline to Day 1 (Part 1) and up to Day 5 after multiple drug administration (Part 2).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AK0529 in people with RESPIRATORY SYNCYTIAL VIRUS INFECTIONS, run by Shanghai Ark Biopharmaceutical Co., Ltd. at 28 sites in 8 countries.

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 5 inclusion and 20 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: finished, as of the sponsor's last update on 20 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 28 sites in Malaysia, Taiwan, Lebanon, Turkey (Türkiye), Australia and 3 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

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

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of Adverse Events during the study (time frame: Day -4 to single dose Day 7 (Part 1) and Day -3 to multiple dose Day 14 (Part 2)). 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?

On the ClinicalTrials.gov record for NCT02654171, which also lists 2 linked publications.

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 20 Feb 2024.
