About this study

Official title: Panobinostat Combined With High-Dose Gemcitabine/Busulfan/Melphalan With Autologous Stem Cell Transplant for Patients With Refractory/Relapsed Myeloma

This phase II trial studies how well panobinostat, gemcitabine hydrochloride, busulfan, and melphalan before stem cell transplant work in treating patients with multiple myeloma that does not respond to treatment (refractory) or has returned (relapsed). Panobinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving high-dose chemotherapy, such as gemcitabine hydrochloride, busulfan, and melphalan, before a peripheral blood stem cell transplant helps kill any cancer cells that are in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. Previously collected stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the progression-free survival (PFS) in patients with refractory or relapsed myeloma receiving panobinostat/gemcitabine hydrochloride (gemcitabine)/busulfan/melphalan (panobinostat/Gem/Bu/Mel) with autologous stem-cell transplant, either as a first or a salvage stem-cell transplant.

SECONDARY OBJECTIVES:

  1. To evaluate the complete response (CR) rate. II. To determine the overall survival (OS). III. To determine the CR + very good partial remission (VGPR) rate. IV. To determine the overall response rate (ORR). V. To determine minimal residual disease posttransplant, measured by multiparametric flow cytometry (MFC).

VI. To describe the toxicity profile of panobinostat/Gem/Bu/Mel. VII. To analyze the predictive value of pretransplant levels in myeloma cells of X-box binding protein 1 (XBP1), inositol-requiring enzyme 1 (IRE1), unspliced XBP1 (XBP1u), sliced XBP1 (XPB1s), XBP1u/XPBs ratio and v-myc myelocytomatosis viral oncogene homolog (avian) (Myc), by analyzing their correlation with CR, VGPR+CR and response rate (RR).

VIII. To study the prognostic effect of pretransplant levels in myeloma cells of XBP1, IRE1, XBP1u, XPB1s, XBP1u/XPBs ratio and Myc, by analyzing their correlation with PFS and OS.

OUTLINE:

Patients receive panobinostat orally (PO) once daily (QD) on days -9 to -2, gemcitabine hydrochloride intravenously (IV) over 4 hours on days -8 and -3, busulfan IV over 3 hours on days -8 to -5, and melphalan IV over 30 minutes on days -3 and -2. Patients then undergo autologous peripheral blood stem cell transplant on day 0.

After completion of study treatment, patients are followed up at 1 month, 100 days, 6 months, 1 year, and then every 3-6 months for at least 2 years.

    Measured: 1 year

Secondary outcomes (2)
  1. Overall Survival (OS)

    Number of participants with refractory or relapse Myeloma who still remain alive two years post transplant

    Measured: Up to 2 years

  2. Participants Who Experienced Grade 3 or Higher Adverse Events

    Number of Participants who experienced grade 3 or higher Adverse Events during the first 100 days of the transplant.

    Measured: Up to day 100

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Autologous Hematopoietic Stem Cell Transplantation, Busulfan and Gemcitabine Hydrochloride in people with Plasma Cell Leukemia and Plasmacytoma, run by M.D. Anderson Cancer Center 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 20 inclusion and 24 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 18 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. 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 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?

Yes. Results are posted in the registry (first posted 18 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?

Progression Free Survival (PFS) (time frame: 1 year). 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 18 Mar 2025.
