Despite the recent introduction of novel anti-multiple myeloma (MM) agents, high risk MM remains with poor prognosis and a therapeutic challenge.
Elotuzumab (ELO) is a humanized monoclonal antibody that recognizes CS1/CD139, a molecule highly expressed in MM cells. The ELO (10 mg/kg), lenalidomide (LEN) and dexamethasone (DEX) combination achieves high overall response rates (ORR) and long progression-free survival (PFS) for patients with relapsed/refractory disease (RR) MM and those with impaired renal function. However, its efficacy for MM patients with high risk characteristics is still unknown.
Pomalidomide (POM) is a recently approved immunomodulatory agent (IMiD) that produces response rates for high-risk RRMM patients when used in combination with DEX and other agents, including the proteasome inhibitor (PI) bortezomib (BTZ). POM has also demonstrated activity for LEN refractory patients.
Carfilzomib (CFZ) is a potent second generation PI that has shown to be efficacious for IMiD and BTZ refractory patients as well as high risk patients carrying cytogenetic abnormalities.
In this study, the investigators propose to evaluate efficacy and safety of elotuzumab in combination with pomalidomide, dexamethasone and carfilzomib for high-risk relapsed refractory multiple myeloma patients.
The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.
The following criteria is provided for health care professionals.
Subjects must be adults (age ≥ 18 years at the time of signing the informed consent document) and must meet all of the following inclusion criteria to be enrolled in the study:
† A WOCBP (women of childbearing potential) is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months) WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug (s) plus 5 half-lives of study drug plus 30 days (duration of ovulatory cycle) for a total of 120 days post-treatment completion. Subject must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, and at least 28 days before she starts taking study drugs. WOCBP must also agree to ongoing pregnancy testing. All subjects must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. See Section 10.3.5.2, Appendix 4 and Appendix 5. Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug plus 5 half-lives of the study drug plus 90 days (duration of sperm turnover) for a total of 154 days post-treatment completion. Men must agree to use a latex condom during sexual contact with a WOCBP even if they have had a vasectomy. All subjects must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. See Section 10.3.5, Appendix 4 and Appendix 5
Subjects meeting any of the following exclusion criteria are not to be enrolled in the study:
