Safety and Tolerability Trial of Inhaled Alpha1-Proteinase Inhibitor (Human), Hydrophobic Chromatography Process (Alpha-1 HC) in Subjects With Cystic Fibrosis

January 11, 2016 updated by: Grifols Therapeutics LLC

A Three Week Dose Escalation, Randomized, Double-Blind, Placebo-Controlled Trial to Assess the Safety and Tolerability of 100 mg or 200 mg of Inhaled Alpha-1 HC, Once a Day in Subjects With Cystic Fibrosis.

This was a randomized, double-blind, placebo-controlled, dose escalation study to assess the safety and tolerability of 100 mg and 200 mg of inhaled Alpha-1 HC administered once a day for three weeks in subjects aged 18 years and older with cystic fibrosis (CF). The treatment duration in this study was intended to provide multi-dose safety information prior to proceeding to longer durations of exposure.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Deemed by the Investigator to be a suitable candidate for serial collection of expectorated sputum.

Exclusion Criteria:
