Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Confirmed diagnosis of multiple myeloma as defined by the International Myeloma Working Group (IMWG) criteria.
* Previously treated with at least 1 prior line of multiple myeloma (MM) therapy and must have documented disease progression during or after their most recent therapy.
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
* Must have at least 1 aspect of measurable disease, defined as one of the following;

1. Urine M-protein excretion \>=200 mg per 24-hour, or
2. Serum M-protein concentration \>=0.5 grams per deciliter (g/dL), or
3. Serum free light chain (FLC) assay: involved FLC level \>=10 mg per dL (\>=100 mg per liter) and an abnormal serum free light chain ratio (\<0.26 or \>1.65).
* All prior treatment-related toxicities (defined by National Cancer Institute Common Toxicity Criteria for Adverse Events \[NCI-CTCAE\] version 5.0) must be \<=Grade 1 at the time of enrollment, except for alopecia.
* Adequate organ function

Exclusion Criteria

* Intolerant to daratumumab.
* Refractory to daratumumab or any other anti-CD38 therapy (defined as progressive disease during treatment with anti-CD38 therapy, or within 60 days of completing that treatment).
* Intolerant to bortezomib, or refractory to bortezomib (defined as progressive disease during treatment with a bortezomib-containing regimen of 1.3 mg/m\^2 twice weekly, or within 60 days of completing that treatment). Note: participants with progressive disease during treatment with a weekly bortezomib regimen are allowed.
* Ongoing Grade 2 or higher peripheral neuropathy or neuropathic pain.
* Prior treatment with anti-B-cell maturation antigen (anti-BCMA) therapy.
* Prior allogenic stem cell transplant.
* Any serious and/or unstable pre-existing medical, psychiatric disorder or other conditions, including renal, liver, cardiovascular, or certain prior malignancies.
* Corneal epithelial disease
