About this study

Official title: A Randomized, Open-label, Phase 3 Study in Subjects With Relapsed and Refractory Multiple Myeloma Receiving Carfilzomib in Combination With Dexamethasone, Comparing Once-weekly Versus Twice-weekly Carfilzomib Dosing

The purpose of the study is to compare the progression-free survival (PFS) of once-weekly carfilzomib dosing in combination with dexamethasone to twice-weekly carfilzomib dosing in combination with dexamethasone in adults with relapsed and refractory multiple myeloma, previously treated with bortezomib and an immunomodulatory agent (IMiD).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CarfilzomibDrug

    Also called PR-171, PR171, Kyprolis® (carfilzomib) for Injection

    Carfilzomib was administered as an IV infusion

  • DexamethasoneDrug

    Commercially available dexamethasone was obtained by the investigational site.

Study groups in NCT02412878
Study groupRoleWhat they receive
Once-weekly Carfilzomib 20/70 mg/m² + DexamethasoneExperimentalParticipants received carfilzomib administered by intravenous (IV) infusion on days 1, 8, and 15 of each 28-day cycle (20 mg/m² on day 1 of cycle 1 and 70 mg/m² thereafter). Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.
Receives: Drug: Carfilzomib; Drug: Dexamethasone
Twice-weekly Carfilzomib 20/27 mg/m² + DexamethasoneExperimentalParticipants received carfilzomib administered by IV infusion on days 1, 2, 8, 9, 15, and 16 of each 28-day cycle (20 mg/m² on days 1 and 2 of cycle 1 and 27 mg/m² thereafter). Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.

What is being measured

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

  1. Progression Free Survival

    Progression-free survival (PFS) was defined as the time from randomization to the earlier of disease progression or death due to any cause.

    Disease status was assessed at a central laboratory with serum and urine protein electrophoresis, immunofixation, serum-free light chain (SFLC) assay, bone marrow sample evaluation, serum calcium, plasmacytoma evaluation, and skeletal survey. Response and disease progression were determined using a validated computer algorithm based on the International Myeloma Working Group-Uniform Response Criteria (IMWG-URC).

    Median PFS was derived using the Kaplan-Meier method; participants still alive with no disease progression were censored at the time of their last disease assessment.

    Measured: From randomization until the data cut-off date of 15 June 2017; median (minimum, maximum) follow-up time for PFS was 12.0 (0, 20) and 12.6 (0, 19) months in each treatment group respectively.

Secondary outcomes (4)
  1. Overall Response Rate

    Disease response was evaluated according to the IMWG-URC using a validated computer algorithm. Overall response rate was defined as the percentage of participants with a best overall response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR).

    sCR: As for CR, normal serum free light chain (SFLC) ratio and no clonal cells in bone marrow (BM).

    CR: No immunofixation on serum and urine, disappearance of any soft tissue plasmacytomas and < 5% plasma cells in BM biopsy; VGPR: Serum and urine M-protein detectable by immunofixation but not electrophoresis or ≥ 90% reduction in serum M-protein with urine M-protein <100 mg/24 hours. A ≥ 50% reduction in the size of soft tissue plasmacytomas if present at baseline.

    PR: ≥ 50% reduction of serum M-protein and reduction in urine M-protein by ≥ 90% or to < 200 mg/24 hours. A ≥ 50% reduction in the size of soft tissue plasmacytomas if present at baseline.

    Measured: Disease response was assessed every 28 days until progressive disease, up to the data cut-off date of 15 June 2017; median time on follow-up was 12.0 and 12.6 months in each treatment group respectively.

  2. Overall Survival

    Overall Survival (OS) was defined as the time from randomization to death due to any cause.

    Median overall survival was derived using the Kaplan-Meier method; participants still alive were censored at the date last known to be alive.

    Measured: From randomization until the data cut-off date of 15 June 2017; median (minimum, maximum) follow-up time for OS was 12.6 (0, 20) and 13.2 (0, 19) months in each treatment group respectively.

  3. Number of Participants With Adverse Events (AEs)

    The severity of adverse events was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03, where where Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Life-threatening; Grade 5 = Fatal.

    Treatment-related adverse events are adverse events considered related to at least 1 investigational product by the investigator, including those with unknown relationship.

    Measured: From first dose of study drug up to 30 days after last dose, up to the end of study; median (minimum, maximum) duration of treatment was 29.1 (0.1, 156.3) weeks and 38.0 (0.1, 158.3) weeks in each treatment group respectively.

  4. Plasma Carfilzomib Concentration During Cycle 2

    Concentrations of carfilzomib in plasma were measured using a validated assay method. The lower limit of quantification was 0.100 ng/mL.

    Measured: Cycle 2 day 1 predose, 15 minutes after the start of infusion (once-weekly carfilzomib only), end of infusion, and 30 minutes after the end of infusion

Where is the study taking place?

The record lists 140 sites in Japan, Italy, United States, Spain, Poland and 15 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 13 Dec 2018). 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 (time frame: From randomization until the data cut-off date of 15 June 2017; median (minimum, maximum) follow-up time for PFS was 12.0 (0, 20) and 12.6 (0, 19) months in each treatment group respectively.). 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 NCT02412878, which also lists 7 linked publications.

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 23 Sep 2022.
