Study of Carfilzomib, Lenalidomide, Dexamethasone and Belantamab Mafodotin in Multiple Myeloma
Study of Carfilzomib, Lenalidomide, Dexamethasone and Belantamab Mafodotin in Multiple Myeloma
This research study is being done to learn if the study drug belantamab mafodotin, in
 combination with other standard medications, can improve multiple myeloma. This study will
 also help determine what effects, good and/or bad, this combination of study drugs have on
 subjects and their cancer, and to evaluate the overall response to this study treatment
 combination.
This is a phase I dose escalation and expansion study in RMM and RRMM followed by a single
 arm phase II expansion in high risk, NDMM. The phase I portion of the protocol will utilize a
 standard 3+3 dose escalation design to determine the maximum tolerated dose (MTD) and RP2D of
 the KRd-belantamab mafodotin combination. The phase II portion of the trial is a two-stage
 design that will assess the efficacy and safety of the combination in newly diagnosed,
 high-risk MM patients.
INCLUSION CRITERIA for all subjects:

 1. Written informed consent and HIPAA authorization for release of personal health
 information. NOTE: HIPAA authorization may be included in the informed consent or
 obtained separately.

 2. Age greater than or equal to 18 years at the time of consent. Because no dosing or
 adverse event data are currently available on the use of belantamab mafodotin as a
 single agent or in combination with KRd in subjects less than 18 years of age,
 children are excluded from this study.

 3. ECOG Performance Status of less than or equal to 2

 4. Demonstrate adequate organ function

 5. Adequate cardiac function as defined by a greater than 40% left ventricular ejection
 fraction (LVEF) by ECHO, cardiac MRI or MUGA

 1. Note for patients in phase II: if a cycle of pre-study induction therapy
 containing a PI or anthracycline was administered, assessment of the LVEF must be
 repeated.

 6. For those with symptomatic pulmonary disease with Grade 2 or higher symptoms (e.g.
 COPD, asthma) or other signs / symptoms of pulmonary disease, adequate pulmonary
 function as defined by a FEV1 greater than or equal to 50% of predicted and DLCO/VA
 greater than or equal to 50% of predicted

 7. Females of childbearing potential (FCBP) must have two negative serum pregnancy tests
 during screening: the first within 10-14 days prior to first dose of study treatment
 and the second within 24 hours prior to first dose of study treatment. NOTE: Females
 are considered of childbearing potential unless they are surgically sterile (have
 undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), are
 amenorrhoeic for less than 2 years without history of a hysterectomy and oophorectomy
 must have a follicle stimulating hormone value in the postmenopausal range upon
 screening evaluation; or are postmenopausal (at least 12 consecutive months with no

 from the time of informed consent, while on belantamab mafodotin and lenalidomide. If
 either drug is discontinued, 2 effective forms of contraception should be continued
 until at least 4 weeks after the last dose of lenalidomide, and 1 form of effective
 contraception should be continued until 4 months post last dose of belantamab
 mafodotin. FCBP should use effective contraception or abstinence from consent until 30
 days after last treatment with carfilzomib, and males with a partner of childbearing
 potential must use effective contraception or abstinence for at least 90 days post
 last dose of carfilzomib.

 disease during treatment or within 60 days after cessation of treatment

 2. A line of therapy is defined as one or more cycles of a planned treatment
 program.

 This may consist of one or more planned cycles of single-agent therapy or combination
 therapy, as well as a sequence of treatments administered in a planned manner. A new
 line of therapy starts when a planned course of therapy is modified to include other
 treatment agents (alone or in combination) as a result of disease progression,
 relapse, or toxicity. A new line of therapy also starts when a planned period of
 observation off therapy is interrupted by a need for additional treatment for the
 disease.

 1-21 of a 28-day cycle or its dosing equivalent based on renal function at the time of
 progression)

 INCLUSION CRITERIA - Phase II treatment for high-risk newly diagnosed MM:
