About this study

Official title: A Phase I, Randomized, Vehicle-Controlled, Double-Blind (Sponsor Open) Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single and Repeat Topical Administration of BOS-475 in Healthy Subjects and Patients With Psoriasis

This study was conducted to evaluate the safety and tolerability of BOS-475 following single and repeat topical administration to healthy participants (Part A), and to evaluate the safety and tolerability of 42-day repeat topical administration of BOS-475 to participants with plaque psoriasis (Part B).

Read the detailed description

In Part A, healthy participants were randomized to receive a single dose application of BOS-475 or vehicle cream. Following a washout period, participants received 7 days of repeated dosing with BOS-475 or vehicle cream on the back, followed by 7 days of repeated dosing of BOS-475 or vehicle cream over the facial area (excluding eye lids and areas around the mouth).

In Part B, participants with mild to moderate stable plaque psoriasis affecting up to 15% of their body surface area were randomized to receive 6 weeks of topical treatment of BOS-475 or vehicle cream.

What is being measured

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

  1. Parts A and B: Number of participants with any adverse event (AEs) and any serious adverse event (SAE)

    Measured: up to Week 8

  2. Parts A and B: Change from baseline in the application site tolerability assessment score

    Change from baseline in the application site tolerability assessment score was measured using the Topical Application Site Tolerability Assessment Scale (5-point scale ranging from 0-no irritation to 4-very severe irritation).

    Measured: up to Week 8

  3. Parts A and B: Number of participants with any clinically significant change from baseline in clinical laboratory parameter values

    Measured: up to Week 8

  4. Parts A and B: Number of participants with any clinically significant change from baseline in vital sign values

    Measured: up to Week 8

  5. Parts A and B: Number of participants with any clinically significant change from baseline in electrocardiogram (ECG) findings

    Measured: up to Week 8

Secondary outcomes (2)
  1. Part A: Plasma concentration of BOS-475

    Measured: Day 1, predose and 1, 2, 4, 8, 24, 48, and 72 hours postdose; Days 5, 8, 9, and 10, predose; Day 11, predose and 1, 2, 4, 8, and 24 hours postdose; Days 15 to 17, predose; Day 18, predose and 1, 2, 4, 8, and 24 hours postdose

  2. Part B: Plasma concentration of BOS-475

    Measured: Days 1, 2, 8, 21, 28, and 35: predose. Day 14: predose; 1 (±15 minutes [min]), 2 (±15 min), 4 (±30 min), and 8 (±2 hours [hr]) hr postdose. Day 15: predose (24 hr [±2 hr] postdose from previous dose on Day 14); at time of study visits on Days 43 and 56

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BOS-475 in people with Psoriasis, run by Boston Pharmaceuticals at 3 sites in Australia.

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 21 inclusion and 17 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 18 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Australia. 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 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?

Parts A and B: Number of participants with any adverse event (AEs) and any serious adverse event (SAE) (time frame: up to Week 8). The study lists 5 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 18 Nov 2020.
