  • 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.

Who cannot join

  • 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.
Show all 9Show fewer
  • 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.

About this study

Official title: 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.

Being tested
ALX-0651, Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ALX-0651Biological

What is being measured

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

  1. Number of treatment emergent adverse events

    Measured: until 1 month after study drug administration

Secondary outcomes (2)
  1. maximum plasma concentration (Cmax) of ALX-0651

    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.

    Measured: from predose until 48 hours after study drug administration

  2. CD34 positive cell count in blood

    Measured: from predose until 14 days after study drug administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALX-0651 in people with Healthy Volunteers, run by Ablynx, a Sanofi company at 1 site in Netherlands.

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 10 inclusion and 9 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: stopped early, as of the sponsor's last update on 17 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. 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 was stopped early (reason given: Proof of principle established with completed SAD part). Results are not available in the source record.

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?

Number of treatment emergent adverse events (time frame: until 1 month after study drug administration). 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 17 Apr 2012.
