About

This phase II trial investigates whether patients greater than or equal to 65 years of age diagnosed with myeloma or another plasma cell malignancy will have better outcomes with transplant followed by maintenance therapy, as primarily measured by progression-free survival, versus non-transplant approaches.

Full description

PRIMARY OBJECTIVES:

I. To evaluate the progression-free survival (PFS) from the start of dexamethasone, cisplatin, Adriamycin (doxorubicin),Cytoxan (cyclophosphamide), etoposide (DPACE) for all participants who have had at least one day of protocol treatment.

II. To evaluate how well such therapy is tolerated in patients mainly over the age of 65 years by assessing severe complications (intensive care unit [ICU] admission, death) and the percentage of participants able to complete the full course of therapy.

SECONDARY OBJECTIVES:

I. To evaluate Quality-Of-Life post-transplant using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire QLQ-C30 and QLC-MY20.

OUTLINE:

INDUCTION THERAPY: Patients receive dexamethasone orally (PO) on days 1-4 and 8-11, cisplatin intravenously (IV) continuously, doxorubicin hydrochloride IV continuously, cyclophosphamide IV, and etoposide IV on days 1-4. Patients then receive pegfilgrastim subcutaneously (SQ) on days 6 and 13 and undergo collection of stem cells when white blood cell (WBC) and cluster of differentiation (CD)34 counts are within program range. Following stem cell collection, patients may receive interim dexamethasone PO on days 1-4, every 14 days at the discretion of the treating physician.

TRANSPLANT: Beginning between 4 weeks to 6 months after the first day of induction therapy, patients receive as transplant conditioning regimen dexamethasone PO on days -4 to -1 and days +2 through +5, bortezomib IV bolus on days -4, -1, 2, and 5, thalidomide PO on days -4 to 5, and melphalan IV on days -4 and -1. Patients undergo autologous peripheral blood stem cell transplant (PBSCT) on day 0. Between transplant and consolidation therapy, patients receive dexamethasone PO on days 1-4 every 21 days and thalidomide PO daily.

CONSOLIDATION THERAPY: If administered, post-transplant consolidation may begin 4-6 weeks after transplant but should occur no more than 4 months later. Most patients will not receive consolidation. Those that do will receive dexamethasone PO on days 1-4 and 8-11, thalidomide PO on days 1-11, bortezomib IV on days 1, 4, 8, and 11, cisplatin IV continuously, doxorubicin hydrochloride IV continuously, cyclophosphamide IV continuously, and etoposide IV continuously on days 1-4.

MAINTENANCE THERAPY YEAR 1: Beginning 6 weeks-6 months after consolidation therapy or 4 weeks to 6 months after transplant if consolidation is skipped, patients receive bortezomib IV bolus on days 1, 4, 15, and 18, thalidomide PO QD on days 1-28, and dexamethasone PO on days 1-4 and 15-18. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

MAINTENANCE THERAPY YEAR 2: Patients receive bortezomib IV on days 1, 4, 15, and 18, cyclophosphamide PO or IV on days 1 and 15, and dexamethasone PO QD on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at least once annually at the study center, but serum for MM marker results will be sent to the study site for close monitoring of PFS .

Inclusion criteria

Participants must have had a diagnosis of symptomatic multiple myeloma (MM), MM + amyloidosis, or POEMS (osteosclerotic myeloma: polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) requiring treatment; participants with a previous history of smoldering myeloma will be eligible if there is evidence of progressive disease requiring chemotherapy; Note that study participants do not need to have active disease at the time of study entry, as participants may have received up to 12 months of prior chemotherapy, which might have induced a response
Protein criteria must be present at diagnosis (quantifiable M-component of IgG, IgA, IgD, or IgE and/or urinary kappa or lambda light chain, Bence-Jones protein, or Free Kappa Light Chain or Free Lambda Light Chain) in order to evaluate response. Non-secretory participants are eligible provided the participant has > 20% plasmacytosis OR multiple (≥3) plasmacytomas or lesions on MRI at the time of diagnosis or study enrollment , OR the presence of lesions on PET/CT scan or skeletal survey at diagnosis or study enrollment.
Participants must have received ≤12 months of prior chemotherapy for this disease without evidence of progressive disease with treatment. Participants may have received prior radiotherapy provided approval has been obtained from the PI. Participants with a history of radiation who have a platelet count <150,000 due to radiation (disease, chemo, and other factors have been ruled out) will be excluded from this study.
Participants must not have had a prior transplant
Participants must be 65-85 years of age at the time of study entry.
Ejection fraction by echocardiogram (ECHO) or multigated acquisition scan (MUGA) of >= 40% performed
Participants must have adequate pulmonary function studies (PFTs), >= 50% of predicted on mechanical aspects (forced expiratory volume in 1 second [FEV^1}, forced vital capacity [FVC]) and diffusion capacity (diffusion capacity of the lung for carbon monoxide [DLCO]) >= 50% of predicted (adjusted for hemoglobin); if the participant is unable to complete pulmonary function tests (PFTs) due to disease-related pain or other circumstances that make it difficult to reliably perform PFTs, documentation of pulmonary function adequate for transplant will occur via a CT scan without evidence of major pulmonary disease, and arterial blood gas results
Participants must have a creatinine < 3 mg/dl and a GFR >30mL/min/1.73m2
Participants must have a performance status of 0-2 based on Eastern Cooperative Oncology Group (ECOG) criteria; participants with a poor performance status (3-4) based solely on bone pain will be eligible, provided there is documentation to verify this
Participants must sign the most current institutional review board (IRB)-approved study (informed consent form) ICF

Exclusion criteria

Prior autologous or allogeneic transplant
Progressive disease on prior treatment
Platelet count < 30 x 10^9/L, unless myeloma-related; if MM-related (hypercellular marrow biopsy of > 80% and packed with at least 80% plasma cells) the enrolling investigator must document this
> Grade 3 neuropathy
Known hypersensitivity to bortezomib, boron, or mannitol
Uncontrolled diabetes on appropriate therapy
Recent (=< 6 months) myocardial infarction, unstable angina, difficult to control congestive heart failure, uncontrolled hypertension on appropriate therapy, or difficult-to-control cardiac arrhythmias
Participants must not have a creatinine >3 mg/dl or a GFR <30mL/min/1.73m2.
Participants must not have a concurrent malignancy unless it can be adequately treated by non-chemotherapeutic intervention; participants may have a history of prior malignancy, provided that he/she has not had any chemotherapy within 365 days of study entry AND that life expectancy exceeds 5 years at the time of study entry
Participants must not have life-threatening co-morbidities

Once recovered, participants start thalidomide daily and dexamethasone x 4 days every 21 days.
