- Dose Escalation Part A: To determine the maximum tolerated dose (MTD) of SAR442085
administered as a single agent in patients with relapsed or refractory multiple myeloma
(RRMM), and determine the recommended Phase 2 dose (RP2D) for the subsequent Expansion
- Dose Expansion Part B: To assess the antitumor activity of single agent of SAR442085 at
the RP2D in patients with RRMM
- To characterize the safety profile of SAR442085
- To characterize the pharmacokinetics (PK) profile of SAR442085 when administered as a
- To evaluate the potential immunogenicity of SAR442085
- To assess preliminary evidence of antitumor activity in the Dose Escalation Part A

toxicity, withdrawal of informed consent, or other reason why investigator considers it
appropriate to discontinue study medication. Once permanently discontinued, study medication
cannot be restarted at later timepoint.

induction regimen with autologous stem cell transplantation, followed by maintenance
regimen). (2) Prior therapy for multiple myeloma has included at least 1 proteasome
inhibitor (bortezomib, carfilzomib, ixazomib), at least 1 immunomodulatory agent
(lenalidomide, thalidomide, pomalidomide) and at least 1 steroid. (3) Prior therapy
has not included an anti-CD38 monoclonal antibody.
