About this study

Official title: A Double-Blind, Placebo-Controlled, Randomized, Single Ascending Dose Study to Investigate Safety, Tolerability, and Pharmacokinetics of ALS-008176 in Healthy Japanese Adult Subjects

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of ALS-008176 following oral administration of single ascending dose of ALS-008176 in healthy Japanese adult participants.

Read the detailed description

This is a double-blind (test or experiment in which neither the person giving the treatment nor the patient knows which treatment the patient is receiving), placebo-controlled, randomized (study medication assigned to participants by chance) and single-center study of ALS-008176. The duration of study will be approximately 6 weeks for each participant. The study consists of 3 parts: Screening Phase (28 days before study commences on Day 1); double-blind Treatment Phase (single oral dose of ALS-008176 or placebo on Day 1 under fasted condition); and Follow up Phase (up to 14 days after study drug administration). All the eligible participants will be randomly assigned to receive either a single oral dose of ALS-008176 or placebo in each group. The planned doses will be escalated in a stepwise fashion if the safety and tolerability in the preceding dose is found acceptable. Participants in Group 1 will receive ALS-008176, 250 milligram (mg) or placebo, Group 2 will receive ALS-008176, 500 mg or placebo and Group 3 will receive ALS-008176, 750 mg or placebo. Study drug will be administered following a 10-hour overnight fast. Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Pharmacokinetics of ALS-008176, ALS-008206, ALS-008112, and its metabolite ALS 008144 will be evaluated primarily. Participants' safety will be monitored throughout the study.

What is being measured

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

  1. Maximum Plasma Concentration (Cmax) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    The Cmax is the maximum observed plasma concentration of ALS 008176, ALS-008206, ALS-008112, and ALS-008144.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  2. Time to Reach the Maximum Plasma Concentration (Tmax) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    The Tmax is the time to reach the maximum observed plasma concentration of ALS 008176, ALS-008206, ALS-008112, and ALS-008144.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  3. Time of Last Measurable Plasma Concentration (Tlast) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    Time of last measurable (non-below quantification limit [non-BQL]) plasma concentration.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  4. Area Under the Plasma Concentration-Time Curve From Time 0 to Time of the Last Observed Quantifiable Concentration (AUC [0-last]) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    The AUC (0-last) is the area under the plasma ALS 008176, ALS-008206, ALS-008112, and ALS-008144 concentration-time curve from time 0 to time of the last observed (non-BQL) quantifiable concentration, calculated by linear-linear trapezoidal summation.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  5. Area Under the Plasma Concentration-Time Curve From 0 to Infinite Time (AUC[0-infinity]) Post Dose of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    The AUC (0-infinity) is the area under the plasma concentration-time curve from time 0 to infinite time, calculated as the sum of AUC (0-last) and C(last)/lambda(z), in which AUC(0-last) is area under the plasma ALS 008176, ALS-008206, ALS-008112, and ALS-008144 concentration-time curve from time zero to time of the last quantifiable concentration, C(last) is the last observed (non-BQL) quantifiable concentration and lambda(z) is elimination rate constant. Extrapolations of more than 20.00% of the total AUC are reported as approximations.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  6. Percentage of Area Under the Plasma Concentration-Time Curve Obtained by Extrapolation (%AUC[infinity,ex])

    The %AUC[infinity,ex] is calculated by dividing the difference of AUC(0-infinity) and AUC(0-last) by AUC(0-infinity) and then multiplying by 100, (AUC[0-infinity] - AUC[0-last])*100/AUC[0-infinity].

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  8. Apparent Terminal Elimination Rate Constant (Lambda [z]) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

    The Lambda (z) determined by linear regression of the terminal points of the ln-linear plasma concentration-time curve.

    Measured: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose

  9. Apparent Initial Half-life (t[1/2alpha]) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALS-008176 (250 mg), ALS-008176 (500 mg) and ALS-008176 (750 mg) in people with Respiratory Syncytial Virus Infections, run by Janssen Pharmaceutical K.K. at 1 site in Japan.

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 7 inclusion and 5 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 11 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Maximum Plasma Concentration (Cmax) of ALS 008176, ALS-008206, ALS-008112, and ALS-008144 (time frame: Pre-dose; 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120 and 144 hours post-dose). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Jul 2016.
