Summary:
The main goal of this phase II study is to evaluate the overall response rate of
isatuximab, belantamab mafodotin, pomalidomide, and dexamethasone in relapsed and
refractory multiple myeloma. The study drugs provided for research purposes are
isatuximab and belantamab mafodotin.
Detailed description:
This is a phase II study of isatuximab, belantamab mafodotin, pomalidomide, and
dexamethasone in relapsed and refractory multiple myeloma. Approximately 50 participants
will take part in this research study. The primary objective is determining the overall
response rate of the treatment. Treatment is until progression, adverse events, or
withdrawal of consent.

negative/trace.
- Patient has adequate hepatic function, as evidenced by each of the following:
- Serum bilirubin values < 1.5 × ULN. Isolated bilirubin ≥ 1.5 × ULN is acceptable if
bilirubin is fractionated and direction bilirubin <35%. Patients with elevated
bilirubin due to Gilbert's syndrome may be permitted with PI approval (e.g. total
bilirubin <3 mg/dL and normal direct bilirubin); and

Patients with elevated bilirubin due to Gilbert's syndrome may be permitted with PI
approval (e.g. total bilirubin <3 mg/dL and normal direct bilirubin).
- Must be able to take acetylsalicylic acid (ASA) daily as prophylactic
anticoagulation. Patients intolerant to ASA may use low molecular weight heparin,
apixaban, rivaroxaban, or equivalent.

and be willing and able to comply with the requirements of the Pomalyst REMS
program.

testing as required in the Pomalyst REMS program and agree to use a highly effective
method of contraception during the study for 4 months after the last dose of
treatment in the study (see Appendix) and agrees not to donate eggs (ova, oocytes)
for the purpose of reproduction during this period). A WOCBP must have a negative
highly sensitive serum pregnancy test within 72 hours before the first dose of study
intervention and agree to use a highly effective method of contraception during the
study and for 4 months after the last dose of belantamab mafodotin. Note: non
childbearing potential defined as follows (by other than medical reasons):
- ≥ 45 years of age and has not had menses for > 1 year

hysterectomy and oophorectomy must have a follicle stimulating hormone value in
the postmenopausal range upon screening evaluation
- Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation.
Documented hysterectomy or oophorectomy must be confirmed with medical records
of the actual procedure or confirmed by an ultrasound. Tubal ligation must be
confirmed with medical records of the actual procedure.
- A man who is sexually active with a WOCBP (even if they have undergone a successful
vasectomy) must agree to use a barrier method of birth control e.g. either condom
with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap
(diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository
for 6 months after receiving the last dose of study drug.
- Male participants must refrain from donating sperm for 6 months after the last dose
of study drug.

antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs]) must
be screened for hepatitis B virus (HBV) DNA levels. Those with positive HBV viral
load will be excluded. Exception: subjects with serologic findings suggestive of HBV
vaccination (anti-HBs positivity as the only serologic marker) and a known history
of prior HBV vaccination do not need testing for HBV DNA.

response, defined as aviremia at least 12 weeks after completion of antiviral
therapy).

gastrointestinal, respiratory, or inflammatory illness that could preclude study

the preceding 12 months.
- Unstable liver or biliary disease
- Active bacterial, viral, or fungal infection
- Patient has any other medical, psychiatric, or social condition that would preclude
