About this study

Official title: A Single-Dose, Randomized, Double-Blind, Placebo-Controlled, Positive-Controlled, Four-Way Crossover Study to Investigate the Effect of BL-8040 (Motixafortide) on the QTc Interval in Healthy Subjects

The study will assess the corrected QT (QTc) effects (electrocardiogram [ECG]) of motixafortide (BL-8040) 1.25 mg/kg (therapeutic dose) and 2 mg/kg (supratherapeutic dose) following a single subcutaneous (SC) injection relative to placebo in approximately 40 healthy subjects.

Read the detailed description

This is a randomized, double-blind (in respect to BL-8040 and BL-8040-matching placebo dosing), placebo- and positive-controlled, 4-period, 4-way crossover study in healthy subjects.

A continuous 12-lead cardiodynamic ECG recording will be collected for approximately 24 hours on Day -1 of Period 1 for use in the optimized individual corrected QTc (QTcI) baseline calculations.

On Day 1 of Period 1, subjects will be randomized to 1 of 12 treatment sequences. Each treatment sequence comprises 4 treatment periods.

On Day 1 of each period, subjects will receive single-dose SC injection of BL-8040 (therapeutic or supratherapeutic dose), single-dose SC injection of BL-8040-matching placebo, or a single oral dose of moxifloxacin. Cardiodynamic readings, plasma pharmacokinetic (PK) samples, and blood pharmacodynamic (PD) samples will be collected at different time points prior to dosing and up to 24 hours postdose in each period, as appropriate.

There will be a washout period of 5-7 days between dosing in each period.

All subjects who received at least one dose of any study drug (including subjects who terminate the study early) will return to the clinical research unit (CRU) 7 ± 2 days after the last dose for follow-up procedures, and to determine if any adverse event (AE) has occurred since the last study visit.

    Assessment of the QTc effects of motixafortide 1.25 mg/kg and 2 mg/kg following a single SC injection relative to placebo in healthy subjects by evaluation of the relationship between the plasma concentration of motixafortide and ΔΔQTcI (change from baseline in QTcI)

    Measured: Cardiodynamic ECG recordings on Day 1 (day of dosing) at different time points prior to dosing and up to 24 hours post-dose in each period (each period is 24 hours long, a total of 4 periods)

Secondary outcomes (6)
  1. Evaluation of AEs, 12-lead Safety ECGs, Vital Signs, Clinical Laboratory Tests, and Physical Examinations.

    Evaluation of safety (by assessing adverse events (AEs), ECGs, vital signs, clinical lab tests, physical examination) and tolerability (by assessing AEs) of single therapeutic and supratherapeutic SC injections of motixafortide in healthy subjects as well as of placebo and moxifloxacin.

    Measured: During the entire study. For each participant starting from Screening until End of Study Visit - approximately 1 month.

  2. PK (AUC0-t and AUC0-inf) of Single Therapeutic and Supratherapeutic SC Injections of Motixafortide (BL-8040) in Healthy Subjects.

    Evaluation of pharmacokinetics (PK) (AUC0-t and AUC0-inf) of single therapeutic and supratherapeutic SC injections of motixafortide in healthy subjects.

    Measured: Blood for motixafortide PK is collected prior to dosing and at 13 different timepoints following dosing up to 24 hours

  3. PK (AUC%Extrap) of Single Therapeutic and Supratherapeutic SC Injections of Motixafortide (BL-8040) in Healthy Subjects.

    Evaluation of PK (AUC%extrap) of single therapeutic and supratherapeutic SC injections of motixafortide in healthy subjects.

    AUC%extrap = (1 - AUC0-t/AUC0-inf) x 100

    Measured: Blood for motixafortide PK is collected prior to dosing and at 13 different timepoints following dosing up to 24 hours

  4. PK (Cmax) of Single Therapeutic and Supratherapeutic SC Injections of Motixafortide (BL-8040) in Healthy Subjects.

    Evaluation of PK (Cmax) of single therapeutic and supratherapeutic SC injections of motixafortide in healthy subjects.

    Measured: Blood for motixafortide PK is collected prior to dosing and at 13 different timepoints following dosing up to 24 hours

  5. PK (Tmax) of Single Therapeutic and Supratherapeutic SC Injections of Motixafortide (BL-8040) in Healthy Subjects.

    Assessment of the effect of single therapeutic and supratherapeutic SC injections of motixafortide on Heart Rate (a non-QT interval ECG parameter) by change from baseline (in bpm).

    "Change from Baseline" at the Baseline timepoint (predosing) is defined as zero.

    Baseline was the average of the derived ECG intervals from the 3 ECG timepoints prior to dosing (-0.75, -0.5, and -0.25 hours) on Day 1.

    Descriptive statistics of ECG parameters (HR) by-timepoint analysis of Change-from-Baseline values was done.

    Measured: ECG recording from prior to dosing (3 timepoints) until 24 hours following administration (13 timepoints after dosing)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 2 mg/kg BL-8040 and 400 mg Moxifloxacin (1x400 mg tablet) in people with Healthy Subjects, run by BioLineRx, Ltd. at 1 site in United States.

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 11 inclusion and 40 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: finished, as of the sponsor's last update on 21 Mar 2025. 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 United States. 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?

Yes. Results are posted in the registry (first posted 21 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

QTc Effect of Single Subcutaneous (SC) Injections of Motixafortide (BL-8040) 1.25 mg/kg and 2 mg/kg (time frame: Cardiodynamic ECG recordings on Day 1 (day of dosing) at different time points prior to dosing and up to 24 hours post-dose in each period (each period is 24 hours long, a total of 4 periods)). 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 21 Mar 2025.
