Efficacy and Safety of Four Escalating Dose Regimens of TPI ASM8 in Patients With Allergic Asthma

November 14, 2013 updated by: Pharmaxis

A Single Center, Open Label, Stepwise, Dose Profiling Study to Evaluate the Efficacy and Safety of Four Dose Regimens of Inhaled TPI ASM8 in Patients With Allergic Asthma

During this proposed clinical trial, the investigators intend to evaluate the pharmacodynamic anti-inflammatory properties and safety of TPI ASM8, by investigating the effect on sputum eosinophils and the airway responses during an allergen challenge at different dose levels.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The early and late asthmatic response were both significantly attenuated by the highest dose of ASM8. The methacholine challenge and other parameters (ECP, mRNA knockdown on CCR3 and B-Chain of IL-3-Il-5 and GMCSF were attenuated by ASM8.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Sputum eosinophils (%) on Day 4 versus Screening for each dose level.
Time Frame: 7 and 24 hrs post-allergen challenge
7 and 24 hrs post-allergen challenge

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Safety and tolerability.
Time Frame: Throughout the study
Throughout the study
Plasma and sputum pharmacokinetic profile at the two highest dose levels.
Time Frame: Dose level 3 and 4
