Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Inclusion Criteria:
- Age >= 18 years
- Diagnosis of RRMM with progressive disease at study entry as per the International
Myeloma Working Group (IMWG) uniform criteria

- Serum M-protein >= 0.5 g/dL
- Urine M-protein >= 200 mg in a 24-hour collection
- Serum free light chain level >= 10 mg/dL provided the free light chain ratio is
abnormal
- For patients with EMD measurable disease by CT or MRI or the CT portion of the PET/CT: Must have at least one lesion that has a single diameter of ≥ 2 cm. Skin lesions can be used if the area is ≥ 2cm in at least one diameter and measured with a ruler.
- Bone marrow plasma cells >= 30%
- Patients with IgA myeloma in whom serum protein electrophoresis is deemed
unreliable, due to co-migration of normal serum proteins with the para protein in
the beta region, may be considered eligible as long as total serum IgA level is
elevated above normal range
- Prior treatment:
- Arm A: At least one of the following must be true: (1) Subjects must have been
previously treated with at least 3 prior lines of therapy, including a proteasome
inhibitor and an immunomodulatory drug (IMiD) (2) Subjects who are refractory to
carfilzomib and/or pomalidomide may enroll in Arm A using the quadruplet regimen,
SKPd, provided carfilzomib, pomalidomide and dexamethasone (KPd) triplet is not
the most recent line of prior therapy and that they have been previously treated
with at least 3 prior lines of therapy, including a proteasome inhibitor and an
IMiD. Carfilzomib/Pomalidomide refractory status is defined by the IMWG criteria:
disease that is nonresponsive (stable disease [SD] or progressive disease [PD])
while on therapy, or progresses within 60 days of last therapy in patients who
have achieved minimal response (MR) or better at some point previously before
then progressing in their disease course.
- Arm B: Subjects must have progressive disease and been exposed to up to 2 prior
lines of therapy, including a proteasome inhibitor and lenalidomide

phase of the study) and ability to adhere with the study visit schedule and other
protocol procedures

- Willingness to follow strict birth control measures as suggested by the study: Female
subjects of childbearing potential should be willing to use 2 methods of birth control
or be surgically sterile, or abstain from heterosexual activity for 28 days prior to
starting pomalidomide, during the course of the study, during any dose interruptions,
and through 30 days after last dose of pomalidomide and carfilzomib. Female subjects
of child bearing potential are those who 1) have achieved menarche at some point, 2)
have not undergone a hysterectomy or bilateral oophorectomy or 3) have not been
naturally postmenopausal (amenorrhea following cancer therapy does not rule out
childbearing potential) for at least 24 consecutive months (i.e., has had menses at
any time in the preceding 24 consecutive months). Note: Abstinence is acceptable if
this is the usual lifestyle and preferred contraception for the subject. Male subjects
must agree to practice abstinence or use an effective barrier method of contraception
starting with the first dose of carfilzomib or pomalidomide through 6 months after
last dose of pomalidomide and carfilzomib if sexually active with a female of
childbearing potential. Note: Abstinence is acceptable if this is the usual lifestyle
and preferred contraception for the subject. Other acceptable methods of contraception
are condoms with contraceptive foam, oral, implantable or injectable contraceptives,
contraceptive patch, intrauterine device, diaphragm with spermicidal gel, or a sexual
partner who is surgically sterilized or post-menopausal. All subjects must agree to
follow the local requirements for pomalidomide counseling, pregnancy testing, and
birth control; and be willing and able to comply with the local requirements (for
example, periodic pregnancy tests, safety labs, etc.)
