Clinical Trial Summary

The purpose of this study is to develop a novel platform for allo-SCT in multiple myeloma (MM) with the idea of maximizing anti-myeloma effect with conditioning and minimizing GvHD (graft versus host disease). Specifically, the investigators will use the Flu/Mel (fludarabine and melphalan) regimen. For GvHD prophylaxis, the investigators use the Hopkins PT-Cy (post-transplant cyclophosphamide) platform with the novelty of adding tocilizumab as both an anti-myeloma therapy and as a method to reduce GvHD. IL-6 has an important role in promoting the growth of myeloma cells and progression of disease.

• No active hepatitis

• Negative for HTLV and HIV

• Not pregnant

• Normal bone marrow and organ function as defined below within 14 days prior to first study drug dose (conditioning regimen):

• Total bilirubin = 2.5 mg/dl

• AST (SGOT) and ALT (SGPT) = 2.5 x ULN

• Creatinine = 2.0 x ULN OR estimated creatinine clearance = 30 mL/min/1.73 m2 by Cockcroft-Gault Formula (See Appendix C)

• Oxygen saturation = 90% on room air

• LVEF = 40%

• FEV1 and FVC = 40% predicted, DLCOc = 40% predicted

• Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry through Day +100 visit. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.

• Able to understand and willing to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

• Receiving renal replacement therapy, hemodialysis, or peritoneal dialysis.

• Presence of another concurrent malignancy requiring treatment.

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

• Presence of an uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Pregnant and/or breastfeeding.

• Previous treatment with tocilizumab (TCZ).

• Immunization with a live/attenuated vaccine within 28 days prior to conditioning.

• Any history of recent serious bacterial, viral, fungal, or other opportunistic infections, precluding a stem cell transplant according to the treating physician.

• Serologic evidence of HIV

• Active infection with Hepatitis A, B, or C. Active infection is defined as serologic positivity and elevated liver function tests.

• History of tuberculosis

• Active infection with EBV as defined as EBV viral load = 10,000 copies per mL of whole blood; EBV viral load testing is only required if the patient has clinical signs or symptoms suggestive of active EBV infection

• Active infection with CMV as defined as CMV viral load = 10,000 copies per mL of whole blood; CMV viral load testing is only required if the patient has clinical signs or symptoms suggestive of active CMV infection

• History of complicated diverticulitis, including fistulae, abscess formation or gastrointestinal (GI) perforation.

• Pre-existing CNS demyelination or seizure disorders

• Major surgery within preceding 8 weeks

• Body weight >150kg

• History of severe allergic or anaphylactic reactions to human, humanized, or murine monoclonal antibodies.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and tolerability of regimen as measured by grade and frequency of adverse events	Adverse events will be graded using NCI CTCAE v4.0 and summarized by grade and frequency	Day +100	Yes
Secondary	Cumulative incidence and severity of acute GvHD		6 months	Yes
Secondary	Cumulative incidence and severity of chronic GvHD		1 year	Yes
Secondary	Non-relapse mortality (NRM)	-NRM is defined as death occurring in a patient from causes other than disease relapse or progression	1 year	Yes
Secondary	Non-relapse mortality (NRM)	-NRM is defined as death occurring in a patient from causes other than disease relapse or progression	Day +100	Yes
Secondary	Progression-free survival (PFS)	-PFS is defined as the duration from transplant to time of first progression, death, relapse after CR, or the date the patient was last known to be in remission.	1 year	No
Secondary	Overall survival (OS)	-OS is defined as the duration from the time of transplant to death or last follow-up.	1 year	No
Secondary	Time to neutrophil engraftment	Neutrophil engraftment is defined as ANC > 0.5 × 10^9/L × 3 consecutive daily assessments. The first of 3 consecutive days for which ANC > 0.5 × 10^9/L will be recorded as the date of neutrophil engraftment. Time to neutrophil engraftment will be calculated as the time from the date of the ASCT to the date of neutrophil engraftment.; Non-engraftment is defined as failure to reach an ANC > 0.5 × 10^9/L × 3 consecutive daily assessments by Day +30.	Day +30	No
Secondary	Time to platelet engraftment	Platelet engraftment is defined as an untransfused platelet measurement > 20,000/ x10^9/L × 3 consecutive daily assessments. The first of 3 consecutive days for which the untransfused platelet measurement is > 20,000 x 10^9/L will be recorded as the date of platelet engraftment. Time to platelet engraftment will be calculated as the time from receiving the date of ASCT to the date of platelet engraftment.
