Safety and Pharmacokinetic Study of Escalating Multiple Doses of an Iron Chelator in Patients With Iron Overload

February 8, 2012 updated by: FerroKin BioSciences, Inc.

A PHASE 1b OPEN LABEL, MULTI-CENTER, ESCALATING MULTIPLE DOSE STUDY TO ASSESS THE SAFETY, TOLERABILITY, PHARMACOKINETICS AND PHARMACODYNAMICS OF FBS0701 IN PATIENTS WITH TRANSFUSIONAL IRON OVERLOAD

The purpose of this research study is to study the safety of increasing doses of FBS0701, and to see how quickly the study medication is absorbed and how quickly it disappears from the bloodstream. FBS0701 is a new, oral iron chelator - a medication taken by mouth that increases the body's elimination of iron. Iron chelators are used in patients who develop iron overload from their transfusions. Four increasing doses of FBS0701 will be tested during this study. The study will start with the lowest dose given to 4 patients (3 mg/kg/day. The next group of 4 patients will receive the next high dose (8mg/kg/day only after the results of the first 4 patients are examined and it is determined safe to continue. Participating patients will take the study medication for 7 days and be followed for 28 days after their last dose to determine if they have any reactions to the study medication - therefore a total of 35 days on study. Patients will need to give up to 17 blood samples over the screening period and first 15 days of the study (a total of about 9 tablespoons). Patients will not need to stay overnight in the clinic but will need to visit the clinic 10 times for screening and on-study visits over the 35 days. Patients currently taking an iron chelator will need to stop that treatment for up to 22 days (up to 5 days before they start the study and for 15 days during the study). The results of this study will be helpful in determining the safety of the drug and the best doses of FBS0701 to be used in the next study which will assess the effectiveness of this new iron chelator.

Study Overview

Status

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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
