April 16, 2012 updated by: Ablynx

A Phase I, Single-centre, Randomised, Single-blinded, Placebo-controlled Single Ascending Dose Study, Followed by an Open-label Extension, Evaluating the Safety, Pharmacokinetics, Pharmacodynamics and Efficacy of ALX-0651, Administered Intravenously to Healthy Male Volunteers

The purpose of this first-in-man Phase I study is to determine whether the CXCR4-inhibitor ALX-0651 is safe and effective after single or multiple intravenous administrations to healthy male volunteers.

Study Overview

Status

Status

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

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.
52

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 55 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Healthy male volunteers, aged >= 18 and <= 55 at screening.
  • Willing to consent to using an effective contraceptive method for at least 3 months after test substance administration.
  • Non-smokers, or ex-smokers abstinent from tobacco for at least 1 year.
  • Body mass index (BMI): 19 - 29 kg/m2 (extremes included).
  • Haematology and chemistry parameters within normal range or showing no clinically relevant deviations, as judged by the Medical Investigator. For haematology, haemoglobin and white blood cell (WBC) count must be within normal limits. For chemistry, calcium, alkaline phosphatase (ALP), (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) and lactate dehydrogenase (LDH) must be within normal limits.
  • Normal electrocardiogram, showing no clinically relevant deviations, as judged by the Investigator. QTc <= 450 ms.
  • No history or presence of diseases of the kidneys, heart, lungs, liver, gastrointestinal tract or endocrine organs, or other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs.
  • No history of clinically relevant allergies.
  • Obtained, signed and dated informed consent.
  • Ability and willingness to comply with protocol requirements.

Exclusion Criteria:

  • Intake of any prescribed systemic or topical medication within 14 days prior to dosing.
  • Intake of vitamin A derivates or retinoids within 30 days prior to the start of drug administration.
  • History of thrombosis.
  • Chronic infection or acute significant infection or fever within the last 5 weeks prior to the start of test substance administration.
  • Subjects with any abnormality of the spleen (confirmed by echography) or history of splenic disease, or subjects that underwent splenectomy in the past.
  • Blood donation (>500 ml) or a comparable blood loss within three months prior to the start of drug administration.
  • Subjects who, in the investigator's opinion, may not be capable of following the study schedule for any reason, with special emphasis on eligibility for the aphaeresis procedure.
  • Participation in an investigational drug study within 60 days prior to drug administration, or within less than 6 times the terminal elimination half-life of the test substance used in the respective trial (whichever is longer).
  • Malignancy, or prior malignancy, with a disease-free interval of < 5 years after diagnosis and intervention, except curative treatment for non-melanoma skin cancer or resected carcinoma in situ.

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
Number of treatment emergent adverse events
Time Frame: until 1 month after study drug administration
until 1 month after study drug administration

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
Measure Description
Time Frame
maximum plasma concentration (Cmax) of ALX-0651
Time Frame: from predose until 48 hours after study drug administration
Plasma concentration of ALX-0651 will be determined at different timepoints between predose and 48 hours after the last study drug administration. The maximum plasma concentration (Cmax) of ALX-0651 will be derived from the resulting plasma concentration versus time plots.
from predose until 48 hours after study drug administration
CD34 positive cell count in blood
Time Frame: from predose until 14 days after study drug administration
from predose until 14 days after study drug administration

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
