Clinical Trial Summary

This study is being conducted to test the possibility that a combination of three drugs, pomalidomide and everolimus with dexamethasone, may improve patient responses when compared with use of either drug alone, with dexamethasone in refractory/relapsed multiple myeloma.


Description:

Given that pomalidomide is an FDA approved drug for patients with relapsed or progressive myeloma, and everolimus has been shown to have single agent activity in relapsed myeloma, it seems reasonable to combine these two active drugs in patients with relapsed/refractory disease. Given that low dose dexamethasone dramatically improved the response rate of pomalidomide, this drug will be added to the combination.

Eligibility Inclusion Criteria:

Age > 18 years

Relapsed or progressive multiple myeloma (MM) (Progressive Disease), defined as a 25% increase from the lowest response value in ANY of the following:

Serum M-protein (absolute increase =0.5 g/dL)

There is an unequivocal increase in the size of previously existing lesions; or

The development of an otherwise unexplained serum calcium >11.5 mg/dL

Have received 1, but no more than 4 prior treatment regimens or lines of therapy for MM (Induction therapy followed by stem cell transplant & consolidation/maintenance therapy will be considered as one line of therapy)

Evaluable MM with, at least one of the following, assessed within 21 days prior to randomization:

Serum M-protein = 0.5 g/dL, or Urine M-protein = 200 mg/24 hour, or

In absence of detectable serum or urine M-protein, serum FLC (SFLC) > 100 mg/L (involved light chain) and/or an abnormal kappa/lamda ratio (>4:1 or <2:1), or

A female of child-bearing potential is considered to be any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

- No hysterectomy or bilateral oophorectomy; or

- Not naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).

Male patients must use an effective barrier method of contraception during study and for 3 months following the last dose if sexually active with a female of child-bearing potential.

Exclusion Criteria:

Have had chemotherapy or radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.

Receiving any other investigational agents. Minimum 4 week "washout" period is required.

History of allergic reactions attributed to compounds of similar chemical or biologic composition to pomalidomide, everolimus, or other agents used in the study.

Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Pregnant or nursing (due to the rick for congenital abnormalities and the potential of this regimen to harm nursing infants).

Glucocorticoid therapy (prednisone > 30 mg/day or equivalent) within 14 days prior to randomization.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes).

Plasma cell leukemia or circulating plasma cells = 2 × 10^9/L.

Waldenstrom's Macroglobulinemia.

Patients with known amyloidosis.

Focal radiation therapy within 7 days prior to randomization. Radiation therapy to an extended field involving a significant volume of bone marrow within 21 days prior to randomization (i.e., prior radiation must have been to less than 30% of the bone marrow).

Immunotherapy within 21 days prior to randomization.

Myelodysplastic syndrome

Major surgery (excluding kyphoplasty) within 28 days

Known cirrhosis.

Significant neuropathy (Grades 3 to 4, or Grade 2 with pain) within 14 days

Ongoing graft-vs-host disease.

Using CYP3A4 inhibitors such as Ketoconazole, Ritonavir, Itraconazole, Erythromycin, Clarithromycin, Nelfinavir, Fluconazole, Amiodarone, Cyclosporine, Diltiazem, nefazadone,fluvoxamine, verapamil, chloramphenicol, Indinavir or saquinavir within 7 days of treatment.

Study Design

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment


Intervention

Drug:
Combination therapy
Following determination of the maximum tolerated dosages in the phase I portion of this study, all patients enrolled in the extension portion will receive the predetermined dosage combination of pomalidomide, everolimus and dexamethasone. Cycles will span 28 days. Dosage schedules will be: Everolimus daily for 28 days of a 28 day cycle; Pomalidomide daily for 21 days of a 28 day cycle Dexamethasone once weekly (on days 1,8,15,22) of a 28 day cycle.

Outcome

Type Measure Description Time frame Safety issue
Primary Maximum Tolerated Dosage (MTD)(Phase I) The Maximum Tolerated Dose (MTD) will be determined by first identifying the dose level at which >= 30% of patients experience a Dose Limiting Toxicity (DLT) according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0, over a 28 day cycle. DLT will be defined based on the rate of drug-related grade 3-5, non-hematological adverse events experienced within the first 4 weeks (1 cycle) for each combined dosage scheme. The MTD will be defined as one dosage level below which DLT was observed in >= 30% of patients. 2 years Yes
Secondary Toxicity Profile The toxicity profile will be described by specific adverse event rates among patients experiencing > grade 3 hematologic events (lasting >7 days) or grades 3-5 non-hematologic adverse events, according to NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0, over a 28 day cycle. Specific events will be described as the numbers of patients experiencing them within each treatment cohort. 2 years Yes
Secondary Anti-tumor Effect Anti-tumor effect will be assessed based on serum protein electrophoresis (SPEP) of the monoclonal protein (M-protein) and plasma concentrations of K/L free light chains (FLC) after each 28-day cycle. Descriptive statistics will be used for this measurement.
Complete response (CR): disappearance of any M-protein and FLC as measured by SPEP and/or FLC. Pre-existing plasmacytomas must have completely resolved.
Partial response (PR): >50% reduction in M-protein and >50% reduction in the difference between involved and uninvolved FLC. Any plasmacytoma must have decreased in size by >50%.
Stable disease: not meeting criteria for CR, PR, or progressive disease (PD). PD: >25% increase from baseline in serum or urine M-protein (serum M-protein must increase by > 0.5 gm/dl; urine M-protein must increase by >200 mg /24 hr); or development of new plasmacytomas or new lytic bone lesions; or a measurable increase in the size of these lesions; or hypercalcemia (>11.5 mg/dl) attributed to MM.
3.5 years No
Secondary Overall Response Rate (RR) ORR is the percentage of patients with a > Partial Response (PR). Response is assessed based on serum protein electrophoresis (SPEP) of the monoclonal protein (M-protein) and plasma concentrations of K/L free light chains (FLC) after each 28-day cycle.
Complete response (CR): disappearance of any M-protein and FLC as measured by SPEP and/or FLC. Pre-existing plasmacytomas must have completely resolved.
PR: >50% reduction in M-protein and >50% reduction in the difference between involved and uninvolved FLC. Any plasmacytoma must have decreased in size by >50%.
Stable disease: not meeting criteria for CR, PR, or progressive disease (PD). PD: >25% increase from baseline in serum or urine M-protein (serum M-protein must increase by > 0.5 gm/dl; urine M-protein must increase by >200 mg /24 hr); or development of new plasmacytomas or new lytic bone lesions; or a measurable increase in the size of these lesions; or hypercalcemia (>11.5 mg/dl) attributed to MM.
