Trial summary

This phase II trial studies how well panobinostat, carfilzomib, and dexamethasone work in treating patients with multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory). Panobinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Read more about this study

About this study

Official title: CLBH589DUS108T: Panobinostat With Carfilzomib and Dexamethasone for Relapsed/Refractory Multiple Myeloma: Correlation With In Vitro Chemosensitivity Testing

This phase II trial studies how well panobinostat, carfilzomib, and dexamethasone work in treating patients with multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory). Panobinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as carfilzomib and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Using multiple myeloma cells from patients' blood samples, the researchers will do laboratory tests to look at how well each of the drugs, alone and in different combinations, kill multiple myeloma cells. If the laboratory tests work well, they may be used in the future to help plan treatment for future patients.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To correlate in vitro drug sensitivity testing with clinical response by determining the rate of in vitro drug sensitivity to panobinostat, carfilzomib, and dexamethasone singly and in combination, doublets and triplets.

SECONDARY OBJECTIVE:

  1. To monitor response rates (partial response [PR], very good partial response [VGPR], and complete response) using the International Myeloma Working Group Uniform Response Criteria for Multiple Myeloma.

EXPLORATORY OBJECTIVE:

  1. Progression free survival and overall survival will be assessed for up to 3 years after last dose.

OUTLINE:

Patients receive panobinostat orally (PO) on days 1, 3, 5, 15, 17, and 19. Patients also receive carfilzomib intravenously (IV) and dexamethasone PO on days 1, 2, 8, 9, 15, and 16. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood and/or bone marrow samples for testing via in vitro chemosensitivity assay.

After completion of study treatment, patients are followed up every 3 months for up to 3 years.

What is being measured

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

  1. Best Overall Response, by Subject

    Assessed using the International Myeloma Working Group Uniform Response Criteria for Multiple Myeloma. Key: 1 = very good partial response (VGPR); 2 = partial response (PR); 3 = minimal response (MR); 4 = stable disease (SD); 5 = progressive disease (PD). Please see IC50 and CI results in the other primary outcome measures.

    Measured: 14 months

  2. Multiple Myeloma Cells In-vitro Drug Sensitivity to Panobinostat, by Subject

    Multiple myeloma cells are added to assay with panobinostat. Cell viability and IC50 is determined. IC50 is the inhibitory concentration that kills 50% of cells. Results are reported in concentrations E-9.

    Measured: At baseline

  3. Multiple Myeloma Cells In-vitro Drug Sensitivity to Carfilzomib, by Subject

    Multiple myeloma cells are added to assay with carfilzomib. Cell viability and IC50 is determined. IC50 is the inhibitory concentration that kills 50% of cells.

    Measured: At baseline

  4. Multiple Myeloma Cells In-vitro Drug Sensitivity to Dexamethasone, by Subject

    Multiple myeloma cells are added to assay with dexamethasone. Cell viability and IC50 is determined. IC50 is the inhibitory concentration that kills 50% of cells. Results are reported in concentrations E-6.

    Measured: At baseline

  5. Synergy of Panobinostat and Carfilzomib in Combination, Per Subject.

    Concentration of carfilzomib and panobinostat in combination leading to 90% growth inhibition of multiple myeloma cells in-vitro. The combination index (CI) is calculated using formula: CI = ([D1] in the combination / [D1] alone) + ([D2] in the combination / [D2] alone). Key: CI = 1 no synergy; CI<1 synergy; CI>1 antagonism.

    Measured: At baseline

  6. Synergy of Panobinostat and Dexamethasone in Combination, Per Subject

    Concentration of panobinostat and dexamethasone in combination leading to 90% growth inhibition of multiple myeloma cells in-vitro. The combination index (CI) is calculated using formula: CI = ([D1] in the combination / [D1] alone) + ([D2] in the combination / [D2] alone). Key: CI = 1 no synergy; CI<1 synergy; CI>1 antagonism.

    Measured: At baseline

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Carfilzomib, Chemosensitivity Assay and Dexamethasone in people with Recurrent Plasma Cell Myeloma and Refractory Plasma Cell Myeloma, run by University of Washington 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 14 inclusion and 20 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 9 May 2022. 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 9 May 2022). 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?

Best Overall Response, by Subject (time frame: 14 months). The study lists 6 primary outcomes in all. 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 9 May 2022; AzTrials last refreshed its copy on 7 Nov 2026.
