LCI-HEM-MYE-CRD-002: Carfilzomib-Revlimid-Dexamethasone-Elotuzumab in Relapsed/Refractory Multiple Myeloma

LCI-HEM-MYE-CRD-002: A Phase II Study of Carfilzomib- Revlimid-Dexamethasone-Elotuzumab in Relapsed/Refractory Multiple Myeloma

The study drug elotuzumab, has been clinically shown to be effective in treating relapsed/refractory MM in combination with either bortezomib, or lenalidomide and dexamethasone. Elotuzumab in combination with lenalidomide and dexamethasone is currently approved by the Food and Drug Administration (FDA) for the treatment of patients with multiple myeloma. Carfilzomib is also FDA approved for treating multiple myeloma and frequently given in combination with lenalidomide and dexamethasone for treatment of relapsed/refractory MM. Based on these findings, this study will look at how subjects with relapsed/refractory MM respond to a combination treatment with the following drugs: elotuzumab, carfilzomib, lenalidomide and dexamethasone. The combination of these four drugs is not FDA approved and is experimental.

Study Overview

• Status: Completed
• Conditions: Multiple Myeloma
• Intervention / Treatment: Drug: Elotuzumab

Detailed Description

This single arm, open-label phase II study is designed with the primary objective of evaluating the efficacy of induction therapy comprised of 4 cycles of carfilzomib, lenalidomide, dexamethasone and elotuzumab (KRd+elotuzumab) in terms of very good partial response or better (VGPR+) in subjects with relapsed and/or refractory MM, and comparing to relevant historical controls. Post induction, all subjects will undergo disease evaluation for assessment of the primary endpoint. Maintenance therapy comprised of elotuzumab and lenalidomide (R+elotuzumab) will start directly after induction and continue until relapse or progression.

Description

Inclusion Criteria

Subject must meet all of the following applicable inclusion criteria to participate in this study:

1. Written informed consent and HIPAA authorization for release of personal health information signed by the subject or his/her legally authorized representative.
2. Age >= 18 years at the time of consent.
3. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2 (see Appendix A, Section 18.1).

4. Documented history of relapsed and/or refractory multiple myeloma per IMWG 2016 criteria [22] as defined below (biochemical and/or clinical relapse per IMWG criteria); (NOTE: subjects refractory to bortezomib and/or lenalidomide are eligible; subjects who previously received carfilzomib are eligible provided they experienced a minimal response or better and relapsed >60 days after completion of treatment [see exclusion criteria #2]):

   1. Relapse is defined as progression of disease after an initial response to previous treatment, more than 6 months after discontinuation of treatment.
   2. Refractory is defined as lack of response to previous treatment, progression of disease during treatment, or progression of disease within 6 months of discontinuation of treatment.
5. Prior treatment with one line (and no more than one line) of systemic therapy for MM; NOTE: A new line of therapy is considered to start when a planned course of therapy is modified to include other treatment agents (alone or in combination) as a result of progressive disease (PD), relapse, or toxicity or when a planned period of observation off therapy is interrupted by a need for additional treatment for the disease. Induction therapy and stem cell transplant followed by planned maintenance therapy (provided there is no intervening PD) are considered to be a single line.
6. Subject must have recovered from any treatment-induced toxicities to ≤ grade 1 or baseline

7. Adequate washout from previous therapy:

   1. Prior chemotherapy is completed >3 weeks prior to day 1 of treatment (6 weeks for melphalan, nitrosoureas or monoclonal antibodies).
   2. Autologous transplant completed (referring to day of stem cell infusion) >12 weeks prior to day 1 of treatment; allogeneic transplant >16 weeks prior to day 1 of treatment.
   3. Prior radiotherapy completed at least 2 weeks prior to day 1 of treatment.
   4. Corticosteroid therapy at a dose equivalent to dexamethasone >4mg/day has been completed at least 2 weeks prior to day 1 of treatment.

8. Measurable disease defined as:

   1. Serum M-protein > 0.5 g/dL OR
   2. Urine M-protein ≥200 mg/24 h OR
   3. Involved free light chain (FLC) level ≥10 mg/dL provided serum FLC ratio is abnormal.
9. Demonstrate adequate organ function within 1 week of day 1 of treatment as defined in the table in Sec.tion 3.2 of protocol (#8)
10. Adequate cardiac function as defined by ≥45% Left Ventricular Ejection Fraction (LVEF) by ECHO or MUGA within 28 days prior to day 1 of treatment.
11. Females of childbearing potential (FCBP) must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to day 1 of treatment, and be willing to undergo serial serum or urine pregnancy testing. NOTE: Females are considered of child bearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are postmenopausal (at least 12 consecutive months with no menses without an alternative medical cause).

12. FCBP must be willing to use a highly effective contraceptive method (i.e., achieves a failure rate of <1% per year when used consistently and correctly) plus a second contraceptive method (considered acceptable [failure rate of >1% per year] or highly effective) from the time of informed consent until 6 months after the last protocol prescribed therapy has been discontinued. NOTE: estrogens may further increase the risk of thrombosis (beyond that associated with lenalidomide) and their use should be based on a benefit-risk decision. For the highly effective contraceptive method, a method with low user dependency is preferable but not required (see tables, adapted from:

    http://www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf).

13. Male subjects (even those who have had a vasectomy) who are sexually active with a FCBP must be willing to use latex or synthetic condoms from the time of informed consent until 180 days after the last protocol prescribed therapy has been discontinued. The FCBP partner should also consider contraception recommendations (see inclusion #11).
14. As determined by the enrolling physician, ability of the subject to understand and comply with study procedures for the entire length of the study.

Exclusion Criteria

Subjects meeting any of the criteria below may not participate in the study:

1. Discontinuation of previous lenalidomide, carfilzomib or dexamethasone due to intolerance.
2. If previously treated with carfilzomib, lack of response, progression during or relapsed within 60 days after completion of treatment.
3. Any infection, at the time of screening, requiring systemic therapy (i.e. involving IV antibiotics) (NOTE: at discretion of investigator, subjects with uncomplicated urinary tract infections may be eligible).
4. Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study, and any female subject must agree not to donate eggs during the study and for 4 months after the last protocol prescribed therapy has been discontinued).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With VGPR or Better Response to Induction	The primary endpoint is a binary variable determined for each subject indicating whether the subject achieved a very good partial response (VGPR), complete response (CR), or stringent complete response (sCR) to induction treatment with KRd-Elo, as defined by the IMWG 2016 response criteria. Per IMWG 2016 criteria, VGPR is defined as serum/urine M-protein detectable by immunofixation but not electrophoresis OR >= 90% reduction in serum M protein plus urine M-protein <100 mg/24 h. CR is defined as negative immunofixation on serum and urine, disappearance of any soft tissue plasmacytomas, and <5% plasma cells in bone marrow aspirates. sCR is defined as CR plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry.	From enrollment to the disease response determined at the end of the induction part of regimen (4 cycles of KRd-Elo was planned, but some subjects progressed before the end of induction). The median length of induction was 16 weeks.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	OS is defined as the duration from treatment start date to the date of death from any cause. Subjects who are alive or lost to follow up at the time of the analysis will be censored at the last known date they were alive.	From date of treatment start to date of death, or censored as described; assessed for approximately 5 years.
Progression Free Survival (PFS)	PFS is defined as the duration of time from treatment start date to first occurrence of either progressive disease (PD) or death. PD must be objectively determined per IMWG 2016 criteria, where progression date is date of last assessment that identified PD. If subject died without documented PD, progression date will be death date. For surviving subjects who do not have PD, PFS will be censored at the date of last disease assessment. For subjects who received subsequent anti-cancer therapy prior to documented PD, PFS will be censored at the date of last disease assessment prior to commencement of subsequent therapy. Subjects who have an initial PFS event immediately following 2 or more consecutive missed assessments will be censored at date of last assessment prior to missed assessments.	From treatment start date to date of progression/death, or censored as described; assessed for approximately 3 years.
Time to Disease Progression (TTP)	TTP is defined as the duration of time from treatment start date to first occurrence of either progressive disease (PD) or death related to disease progression. PD must be objectively determined per IMWG 2016 criteria, where progression date is date of last assessment that identified PD. If a subject died for causes related to disease progression then progression date will be date of death. If a subject died for causes other than disease progression, TTP will be censored at the date of other cause mortality. For surviving subjects who do not have PD, TTP will be censored at the date of last disease assessment. For subjects who received subsequent anti-cancer therapy prior to documented PD, TTP will be censored at the date of last disease assessment prior to commencement of subsequent therapy. Subjects who have an initial TTP event immediately following 2 or more consecutive missed assessments will be censored at date of last assessment prior to missed assessments.	From treatment start date to date of progression/death, or censored as described; assessed for approximately 3 years.
Time to Next Treatment (TTNT)	TTNT will be calculated from the time of treatment start until the start of the first subsequent anti-cancer therapy after all protocol directed therapy is completed. For surviving subjects who do not receiving subsequent therapy, TTNT will be censored at the last contact date. For subjects who die before beginning subsequent anti-cancer therapy, TTNT will be censored at the date of death	From treatment start date to date of next treatment, or censored as described; assessed for approximately 3 years.
Number of Subjects With an Objective Response	Objective response was determined for each subject as a binary variable indicating whether the subject achieved a best overall response of partial response (PR), very good partial response (VGPR), complete response (CR), or stringent complete response (sCR) at any time on study treatment as determined by IMWG 2016 response criteria. Per IMWG 2016 criteria, PR is defined as at least 50% reduction of serum M-protein plus reduction in 24 hour urinary M-protein by 90% or to <200 mg/24h. VGPR is defined as serum/urine M-protein detectable by immunofixation but not electrophoresis OR >= 90% reduction in serum M protein plus urine M-protein <100 mg/24 h. CR is defined as negative immunofixation on serum and urine, disappearance of any soft tissue plasmacytomas, and <5% plasma cells in bone marrow aspirates. sCR is defined as CR plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry.	From enrollment to best response while on study treatment; subjects remained on treatment until disease progression or death or unacceptable toxicity. Subjects were on treatment for a median of 12 months.
Duration of Response (DoR)	DoR will be calculated for each subject with a partial response, very good partial response, complete response, or stringent complete response on study treatment. The DoR intervals will be calculated from the time of the first assessment that identified response until disease progression or death. The censoring mechanism for DoR will be the same as described for PFS.	From time of first response to date of progression/death, or censored as described; assessed for approximately 3 years.
