About this study

Official title: A Single-arm, Single Center, Pilot Study of Siltuximab, an Anti-IL6 Therapy, for Patients With Myelofibrosis

The main purpose of this investigational research study is to determine how safe and tolerable the study drug siltuximab is in patients with myelofibrosis (MF). This medication has been approved by the FDA for another condition (multicentric castleman's disease (MCD), but not for myelofibrosis (MF). In MCD, siltuximab resulted in improvement in symptoms and anemia. While MCD and MF are different diseases, they share some common features including a protein call interleukin-6 (IL-6) that may be important in causing symptoms of MCD and MF.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate safety and tolerability of the drug siltuximab in the myelofibrosis patient population.

SECONDARY OBJECTIVES:

  1. To determine clinical improvement (CI). II. To determine the overall response rate (ORR).

TERTIARY OBJECTIVES:

  1. To determine if siltuximab results in improvement in iron dysregulation. II. To determine changes in inflammatory stress that may correlate with clinical response.

OUTLINE:

Patients receive siltuximab intravenously (IV) over 60 minutes on day 1. Patients also undergo bone marrow biopsy and aspiration at baseline and at the end of treatment (within 30 days of last siltuximab dose) or as clinically indicated. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression, unacceptable toxicity, or patient decision to withdraw. Patients who are responding after 6 courses may receive additional siltuximab treatment for up to 1 year at the discretion of the study doctor.

After completion of study treatment, patients are followed up at 30 days.

What is being measured

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

  1. Incidence of Adverse Events

    To evaluate safety and tolerability of the drug siltuximab in the myelofibrosis patient population. Adverse events will be assessed by type, timing, frequency, and attribution and will be graded according to the NCI's common terminology criteria, version 4.03.

    Measured: Up to 30 days after last treatment

Secondary outcomes (4)

  1. Clinical Improvement (CI): changes in symptoms

    Changes in the baseline symptom burden using Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) questionnaire.

    Measured: At baseline and after cycle 3 (9 weeks)

  2. Clinical Improvement (CI): splenomegaly

    To determine spleen response, palpation will be used, using centimeters below the left costal margin, and if body habitus is prohibitive, by ultrasonography.

    Measured: At baseline and after cycle 3 (9 weeks)

  3. Clinical Improvement (CI): Anemia response

    Baseline hemoglobin level and/or transfusion-dependence will be recorded at baseline and compared to results after cycle 3

    Measured: At baseline and after cycle 3 (9 weeks)

  4. Overall Response Rate (ORR)

    The ORR will be assessed after 6 cycles of therapy using standard criteria published by the International Working Group for Myelofibrosis Research and Treatment which will evaluate for complete response, partial response, clinical improvement, or stable disease.

    Measured: After 6 cycles of treatment (18 weeks)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Bone Marrow Aspiration and Biopsy, Laboratory Biomarker Analysis and Siltuximab in people with Myelofibrosis and Polycythemia Vera, run by Northwestern University.

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 24 inclusion and 18 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: withdrawn, as of the sponsor's last update on 24 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

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 phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 withdrawn before enrolling participants, so there are no results.

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?

Incidence of Adverse Events (time frame: Up to 30 days after last treatment). 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 NCT02805868.

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 24 Oct 2016.
