- Intolerant to the anti-CD38 previously received or,

- Progression after initial response on anti-CD38 therapy with a washout period
inferior to 9 months before the first dose of isatuximab SC or IV.

- Participant did not achieve a minimal response or better to at least one of the
previous lines of treatment (ie, primary refractory disease is not eligible).

- Received any investigational drug within 14 days or 5 half-lives of the
investigational drug, whichever is longer.

- Prior anti-cancer therapy within 14 days.

- Any >Grade 1 adverse reaction unresolved from previous treatments according to the
NCI-CTCAE v5.0. The presence of alopecia or peripheral neuropathy = Grade 2 without
pain is allowed.

- Previous allogeneic stem cell transplantation with active Graft Versus Host Disease or
being under immunosuppressive therapy in the last 2 months previously to the inclusion
in the trial.

- Daily requirement for corticosteroids.

- Known to be HIV+ or to have hepatitis A or uncontrolled or active hepatitis B virus
(HBV) infection (patients with positive HBsAg [HBsAg] and/or HBV DNA) or active HCV
(HCV) infection (positive HCV RNA and negative anti-HCV).

- Active tuberculosis and severe infections requiring treatment with antibiotic
parenteral administration.

- Any clinically significant, uncontrolled medical conditions that, in the
Investigator's opinion, would expose excessive risk to the patient or may interfere
with compliance or interpretation of the study results.

- History of erythema multiforme or severe hypersensitivity to prior immunomodulatory
drugs (IMiDs).

- Hypersensitivity or history of intolerance to immunomodulatory drugs (IMiDs),
dexamethasone, mannitol, pregelatinized starch, sodium stearyl fumarate, histidine (as
base and hydrochloride salt), arginine hydrochloride, poloxamer 188, sucrose or any of
the other components of study therapy that are not amenable to premedication with
steroids and histamine H2 blockers or would prohibit further treatment with these
agents.

- Inability to tolerate thromboprophylaxis.

Summary
Brief summary
Primary Objectives:

- To evaluate the safety and tolerability of isatuximab administered subcutaneously (SC)
versus intravenously (IV)

- To assess the safety and tolerability (including local injection site tolerability) of
isatuximab using the (investigational) isatuximab injector device

- To evaluate the pharmacokinetics (PK) of SC and IV isatuximab

Secondary Objectives:

- To estimate absolute bioavailability of SC and IV isatuximab

- To measure receptor occupancy (RO) after isatuximab SC versus IV administration

- To assess efficacy of isatuximab after SC and IV administration

- To assess patient expectations prior to and patient experience and satisfaction after SC
administration

- To evaluate potential immunogenicity of SC or IV isatuximab
