About this study

Official title: Carfilzomib/Cyclophosphamide/Dexamethasone with Maintenance Carfilzomib in Untreated Transplant-eligible Patients with Symptomatic MM to Evaluate the Benefit of Upfront ASCT

The Cardamon trial is a phase 2 trial using the standard chemotherapy drugs cyclophosphamide and dexamethasone in combination with a new drug called Carfilzomib in patients with multiple myeloma.

Read the detailed description

Multiple Myeloma is a cancer of the bone marrow and, for those patients that are young and fit enough, the disease is usually treated with chemotherapy (sometimes called induction chemotherapy) followed by a stem cell transplant using the patient's own stem cells (autograft or Autologous Stem Cell Transplant). Unfortunately almost all patients will experience a relapse at some point following this treatment. After relapse there are a number of treatment options but eventually the disease will become resistant to further therapy.

The use of an Autologous Stem Cell Transplant (or Transplant) after initial chemotherapy treatment has been shown in studies to increase the amount of time that patients are without symptoms of their myeloma before unfortunately their disease relapses. However, recently more effective induction chemotherapy regimens have been developed and patients treated with these new regimens are able to achieve higher and deeper responses than those previously treated on older regimens. Many also achieve complete or very good partial response, which was rare with the traditional chemotherapy regimens.

So, the investigators now do not know if giving patients an Autologous Stem Cell Transplant straight after their initial induction chemotherapy is the best thing to do. It may be that patients who respond well to a new drug containing regimen will obtain most benefit from their stem cells if these stem cells are frozen and stored, so that they can be used when their disease relapses.

In the Cardamon trial, the investigators will directly compare the outcome of patients who receive a transplant, versus those patients who do not and who instead receive Consolidation therapy. After induction treatment and stem cell harvest, patients will be randomly allocated to receive either a transplant or to receive consolidation therapy. Patients in the Cardamon trial will also be given maintenance treatment. This is treatment that is given on an ongoing basis, after the transplant or after the Consolidation therapy. The aim of maintenance treatment is to prolong disease response and delay the time to relapse.

In summary the purpose of the Cardamon study is:

  1. to confirm the high response rate to a new treatment regime that includes Carfilzomib plus 2 standard chemotherapy drugs used for the treatment of Multiple Myeloma,
  2. to investigate whether patients who respond well to this new Carfilzomib-containing induction regimen are able to maintain a long remission period without having an Autologous Stem Cell Transplant 'up-front', and
  3. to find out if maintenance treatment with Carfilzomib is able to further reduce the number of remaining myeloma cells in the bone marrow, using the Minimal Residual Disease test.

What is being measured

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

    Measured: Within 4 weeks of the end of induction treatment

  2. PFS

    Progression free survival at 2 years for both ASCT and non-ASCT (consolidation) arms

    Measured: 2 years after randomisation

Secondary outcomes (6)
  1. To assess toxicity and tolerability of CarCyDex and carfilzomib as maintenance therapy in untreated patients with symptomatic multiple myeloma

    Adverse Events (including peripheral neuropathy), dose reductions and delays, tolerability of the induction and maintenance regimens (treatment delays, discontinuation rates)

    Measured: From start of treatment until 30 days post end of maintenance treatment

  2. Disease response rate

    Disease response rate (sCR, CR, VGPR, PR) to CarCyDex induction

    Measured: Within 4 weeks of the end of induction treatment

  3. PFS

    PFS in both the ASCT and non-ASCT arms

    Measured: Assessed every 6 months from the end of treatment until 36 months post induction

  4. Overall survival

    Overall survival in both the ASCT and non-ASCT arms

    Measured: Assessed every 6 months from the end of treatment until 36 months post induction

  5. MRD conversion following treatment

    Improvement in disease response and conversion from MRD-positive to MRD-negative post ASCT and post Consolidation

    Measured: Baseline, Day 100 post ASCT or within 4 weeks of the end of consolidation treatment

  6. MRD conversion following maintenance

    Improvement in disease response and conversion from MRD-positive to MRD-negative after 6 months of maintenance treatment

    Measured: Baseline, after 6 months of maintenance

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Autologous Stem Cell Transplant (ASCT) and Consolidation with 4 cycles of CarCyDex in people with Multiple Myeloma, run by University College, London at 20 sites in United Kingdom.

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 21 inclusion and 14 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: under way, not looking for participants, as of the sponsor's last update on 6 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United Kingdom. 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?

This study is still under way. Results are not available in the source record yet.

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?

Response rate (time frame: Within 4 weeks of the end of induction 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 NCT02315716, 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 6 Dec 2024.
