Clinical Trial Summary

Explore stem cell collection with or without bortezomib with in-vivo purging in multiple myeloma.

Description:

High dose chemotherapy with autologous stem cell transplant has resulted in improved overall survival and is currently considered an effective first line therapy applicable to the majority of patients with multiple myeloma. However disease relapse is inevitable and remains the primary cause of mortality in this cohort. The purpose of this study is to estimate the proportion of subjects with plasma cell contamination of harvested stem cell product in standard and treatment arms. The study will explore whether or not in-vivo purging of malignant tumor plasma cells will improve progression free survival (PFS) for patients. The study will consist of two groups: Group A: Standard of Care (SOC) stem cell collection without in-vivo purging with bortezomib. Granulocyte colony-stimulating factor (G-CSF) and Mozobil used if needed. Group B: Bortezomib 1.3mg/m^2 will be given subcutaneously (SQ) on days -11 and -8 followed by Granulocyte colony-stimulating factor (G-CSF) on days -4 through -1 prior to stem cell harvest (day 0).

Eligibility

Inclusion Criteria:

• Subjects must meet all of the inclusion criteria to participate in this study.
• Ability to understand, and the willingness to sign a written Informed Consent Form
• Diagnosis of multiple myeloma undergoing planned autologous stem cell transplantation
• Age = 18 years
• Karnofsky Performance Status (KPS) 70 or above, Eastern Cooperative Oncology Group (ECOG) 0, 1 or 2
• Adequate organ and marrow function as defined below:
• leukocytes = 3,000/micro Liter (mcL)
• absolute neutrophil count = 1,500/mcL
• platelets = 100,000/mcL
• total bilirubin within normal institutional limits NOTE: For this study, subjects with bilirubin levels > 1.5 Upper Limit of Normal (ULN) are excluded from enrollment in this study.
• Aspartate Aminotransferase (AST) ( Serum Glutamic Oxaloacetic Transaminase [SGOT]) = 2.5 X institutional upper limit of normal
• Alanine Aminotransferase (ALT) (Serum Pyruvic Glutamic Transaminase [SPGT]) = 2.5 X institutional upper limit of normal
• creatinine within normal institutional limits
• Women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days following completion of therapy. Should a woman or partner become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician and the investigator immediately.
• A woman of child-bearing potential is any female (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the

following criteria:

• Has not undergone a hysterectomy or bilateral oophorectomy; or
• Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)

Exclusion Criteria:

• Subjects meeting any of the exclusion criteria at baseline will be excluded from study participation.
• Current or anticipated use of other investigational agents. NOTE the following clarification for this study: Prohibited Concurrent Therapy: Participation in clinical trials with other investigational agents that are not included in this trial, within 14 days of the start of this trial until 2 weeks after participant has received the last dose of bortezomib for mobilization.
• Hypersensitivity to bortezomib, boron or mannitol or Granulocyte colony-stimulating factor (G-CSF)
• Subject has received > 6 months of lenalidomide (Revlimid®) therapy prior to stem cell collection
• Subject has known brain metastases. Presence of brain metastases should be excluded from this clinical trial because of poor prognosis and because patients often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
• Grade 3 or higher peripheral neuropathy
• Bilirubin levels > 1.5 ULN
• Uncontrolled inter-current illness including, but not limited to
• ongoing or active infection
• symptomatic congestive heart failure
• unstable angina pectoris
• cardiac arrhythmia
• psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant or nursing: There is a potential for congenital abnormalities and for this regimen to harm nursing infants.

Intervention

Drug:
• Bortezomib
Bortezomib will be given to Group B participants by injection under the skin 11 days and 8 days before stem cell collection.
• Granulocyte colony-stimulating factor (G-CSF)
Granulocyte colony-stimulating factor (G-CSF) will be given to all participants by injection under the skin 4 days and 1 day before stem cell collection, and then continued until the stem cell collection is completed.
• Mozobil
Mozobil will be given to all participants by injection under the skin only if needed per Investigator.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Multiparametric Flow Cytometry - Minimum Residual Disease	Estimate the proportion of subjects with plasma cell contamination (defined as >0.01% and at least 100 cellular events) of harvested stem cell product by multi parametric flow cytometry (MFC) from patients with myeloma undergoing autologous stem cell collection 1) by standard of care mobilization using Granulocyte colony-stimulating factor (G-CSF) with or without Mozobil and 2) after two doses of bortezomib as in vivo purging plus standard of care using G-CSF with or without Mozobil.	Day 0 for all subjects (Day 0 is the day of stem cell collection)
Secondary	Multiparametric Flow Cytometry - Cluster of Differentiation 34 (CD34)Assessment	Estimate the proportion of subjects who have a successful collection of stem cells (> 2 million Cluster of Differentiation 34 (CD34) cells/Kg of body weight) for autologous transplant in both treatment groups.	Within the first 30 days after stem cell collection
Secondary	Cluster of Differentiation 34 (CD34) Enumeration	Estimate the percentage of Cluster of Differentiation 34 (CD34) positive cells in circulating peripheral blood as a measure of mobilization on the days of collection.	Within the first 30 days after stem cell collection
