About this study

Official title: Study of the Anti-EphA3 Monoclonal Antibody KB004 in Subjects With EphA3-Expressing Hematologic Malignancies

This is a global, multicenter, open-label, repeat-dose, Phase 1/2 study consisting of a Dose Escalation Phase (Phase 1) and a Cohort Expansion Phase (Phase 2). In both phases, KB004 will be administered by IV infusion once weekly as part of a 21-day dosing cycle.

Read the detailed description

The purpose of Phase 1 is to determine a maximum tolerated dose (MTD) for KB004 when administered to subjects with hematologic malignancies who meet the entry criteria. Phase 1 has completed enrollment July of 2014, the recommended Phase 2 dose is 250 mg. AML 20 mg Cohort completed enrollment Dec 2014.

The purpose of Phase 2 is to characterize preliminary clinical activity. The Phase 2 portion of the study consists of two parts:

  • Part A: Subjects with AML or MDS who meet the entry criteria
  • Part B: Subjects with MF who meet the entry criteria
Being tested
KB004, Monoclonal Antibody

What is being measured

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

  1. Phase 1: Determine a possible maximum tolerated dose (MTD)

    Measured: Once weekly for the first three weeks of study treatment

  2. Phase 2: To characterize preliminary clinical activity based on the International Working Group (IWG) criteria specific to the hematologic malignancy

    Measured: Evaluations at designated timepoints

Secondary outcomes (4)
  1. Phase 1: Examine clinical activity

    Measured: Evaluations at designated timepoints

  2. Phase 1/2: Safety and Tolerability

    Measured: Duration of study participation

  3. Phase 1/2: Pharmacokinetic profile

    Measured: Cycle 1: multiple timepoints. Thereafter, single samples at designated cycles

  4. Phase 1/2: Assess immunogenicity

    Measured: Cycle 1: multiple timepoints. Thereafter, single samples at designated cycles

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing KB004, Monoclonal Antibody in people with Myelodysplastic Syndrome (MDS) and Myelofibrosis (MF), run by Humanigen, Inc. at 9 sites in 2 countries.

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 7 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: paused, as of the sponsor's last update on 17 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Australia. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

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?

Phase 1: Determine a possible maximum tolerated dose (MTD) (time frame: Once weekly for the first three weeks of study treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01211691, which also lists 1 linked publication.

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 Nov 2015.
