Trial Outcomes & Findings for Cyclophosphamide, Carfilzomib, Thalidomide, and Dexamethasone in Treating Patients With Newly Diagnosed Active Multiple Myeloma (NCT NCT01057225)

NCT ID: NCT01057225

Last Updated: 2017-12-12

Results Overview

To establish the maximum tolerated dose of carfilzomib given in combination with oral cyclophosphamide and thalidomide and dexamethasone. For this protocol, dose-limiting toxicity (DLT) will be defined as an adverse event attributed (definitely, probably, possibly) in the first or second cycle for patients enrolled to Dose Levels -1 and 0 and in the first cycle only for patients enrolled to Dose Levels 1 and 2. We are reporting the number of DLTs

PRIMARY outcome

Timeframe: Following the first 4 cycles of treatment (28 day cycles)

Population: All enrolled patients who began treatment were evaluated for safety and response.

The proportion of patients who have at least a confirmed very good partial response will be calculated by taking the number of patients with a very good partial response or a complete response divided by the total number of patients. A complete response is defined as: * Negative immunofixation of the serum and urine * If at on study, only the measurable non-bone marrow parameter was FLC, normalization of FLC ratio * \< 5% plasma cells in bone marrow * Disappearance of any soft tissue plasmacytomas A very good partial response is defined as: * Serum and urine M-component detectable by immunofixation but not on electrophoresis or * If at on study, serum measurable, ≥ 90% or greater reduction in serum Mcomponent * Urine M-component \<100 mg per 24 hour

SECONDARY outcome

Timeframe: From baseline to progression or death up to 3 years

Population: All of the 64 participants that were eligible and began treatment were evaluated.

PFS was defined as the time from registration to progression or death due to any cause. Progression was defined as any one or more of the following: • Increase of 25% from lowest confirmed response in: Serum M-component (absolute increase must be ≥ 0.5 g/dl)c Urine M-component (absolute increase must be ≥ 200 mg/24 hour) If at on study, only the measurable non-bone marrow parameter was FLC, the difference between involved and uninvolved FLC levels (absolute increase must be \>10 mg/dl) Bone marrow plasma cell percentage (absolute % must be 10%)d Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas • Development of hypercalcemia (corrected serum calcium \>11.5 mg/dl) that can be attributed solely to the plasma cell proliferative disorder

SECONDARY outcome

Timeframe: From baseline to end of active treatment

Population: All enrolled patients who began treatment were evaluated for safety and response.

The time from the date of registration to the date at which the patient is removed from treatment due to progression, adverse events, or refusal. If the patient is considered to be a major treatment violation or is taken off study as a non-protocol failure, the patient will be censored on the date they were removed from treatment. The distribution of time to treatment failure will be estimated using the method of Kaplan-Meier

Survival Time (Phase II)
NA months
The median and 95% confidence interval for the survival time could not be estimated due to too few deaths.

SECONDARY outcome

Timeframe: 12 months

Population: All of the 64 participants that were eligible and began treatment were evaluated.

Progression-free survival time is defined as the time from registration to the earliest date of documentation of disease progression. If a patient dies without a documentation of disease progression the patient will be considered to have had disease progression at the time of their death. If the patient is declared to be a major treatment violation, the patient will be censored on the date the treatment violation was declared to have occurred. In the case of a patient starting treatment and then never returning for any evaluations, the patient will be censored for progression 1 day post-registration. This is reported as the percentage of patients alive and progression free at the 12 month mark.

Progression Free Survival (12 Month)
85 percentage of participants at 12 months
Interval 71.0 to 93.0

SECONDARY outcome

Timeframe: 24 months

Population: All of the 64 participants that were eligible and began treatment were evaluated.

Progression-free survival time is defined as the time from registration to the earliest date of documentation of disease progression. If a patient dies without a documentation of disease progression the patient will be considered to have had disease progression at the time of their death. If the patient is declared to be a major treatment violation, the patient will be censored on the date the treatment violation was declared to have occurred. In the case of a patient starting treatment and then never returning for any evaluations, the patient will be censored for progression 1 day post-registration. This is reported as the percentage of patients alive and progression free at the 24 month mark.
