- Part 1: Number Of Participants Experiencing Dose-limiting Toxicities (DLTs) [ Time Frame: Cycle 1 (Up to 28 days for non-hematologic DLTs and up to 42 days for hematologic DLTs) ]DLTs will be based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0 and will be defined as any of following events: Grade 3 or higher toxicity assessed by the investigator as related to BGB-11417 treatment; and Grade 4 or higher regimen-related organ toxicities

- Part 2: Complete Response (CR) or better [ Time Frame: Upon study termination (Baseline up to first documentation of disease progression [PD] or death from any cause [approximately 4 years]) ]defined as the proportion of patients with a documented CR or sCR
- Part 1: Area under the plasma concentration-time curve (AUC) [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: Maximum observed plasma concentration (Cmax) [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: Time to reach Cmax (tmax) [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: After steady-state: AUC last,ss [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: After steady-state: Cmax, ss [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: After steady-state: trough plasma concentration (Ctrough) ss [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 1: After steady-state: time to reach Cmax (tmax,ss) [ Time Frame: At the end of Cycle 1 (each cycle is 28 days) ]
- Part 2: Time to response (TTR) as assessed by investigator [ Time Frame: Upon study termination (Baseline up to first documentation of disease progression [PD] or death from any cause [approximately 4 years]) ]TTR is defined as the time from start of treatment to first documentation of response of Partial Response (PR) or better
- Part 2: Duration of response (DOR) as assessed by investigator [ Time Frame: Upon study termination (Baseline up to first documentation of disease progression [PD] or death from any cause [approximately 4 years]) ]DOR is defined as the time from the date of the first documented response (PR or better) after treatment initiation until the date of first documented disease progression or death due to MM, whichever occurs first. DOR will be analyzed using the same methods as the PFS analysis, but only for patients who have achieved an overall response of at least PR. The distribution of DOR will be summarized by the Kaplan-Meier method.
- Part 2: Progression-free survival (PFS) as assessed by investigator [ Time Frame: Upon study termination (Baseline up to first documentation of disease progression [PD] or death from any cause [approximately 4 years]) ]PFS is defined as time from start of treatment to the first documentation of disease progression or death, whichever occurs first
- Part 2: Overall survival (OS) as assessed by investigator [ Time Frame: Upon study termination (Baseline up to approximately 4 years) ]OS defined as the time from start of treatment to the date of death due to any cause

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
- A confirmed diagnosis of multiple myeloma (must have an M-component in serum and/or urine)
Measurable disease defined as:
i. M-spike ≥ 500mg/dL, or ii. Urine protein M-spike of ≥ 200 mg/day, or iii. Serum free light chains ≥ 10 mg/dL, and an abnormal κ:λ ratio
Participant has documented relapsed or progressive MM on or after any regimen or who are refractory to the most recent line of therapy.
i. Relapsed MM is defined as previously treated MM that progresses and requires initiation of salvage therapy but does not meet the criteria for refractory MM.
ii. Refractory MM is defined as disease that is nonresponsive (failure to achieve minimal response or development of progressive disease) while on primary or salvage therapy or progresses within 60 days of last therapy.
- Participants in Part 1 should have failed all other available options including having had ≥ 3 prior lines of therapy including a proteasome inhibitor, IMiD agent, and an anti-CD38 monoclonal antibody.
Participants in Part 2 should have had and failed ≥ 1 but ≤ 7 prior lines of therapy and will have had prior treatment with both a proteasome inhibitor and an IMiD agent.
Note: A line of therapy consists of greater ≥ 1 complete cycle of a single agent, a regimen consisting of combination of several drugs, or a planned sequential therapy of various regimens. Induction therapy with consolidation and maintenance following stem cell transplant is considered a single line of therapy.
- Prior treatment with carfilzomib is allowed but the patient must not be considered carfilzomib refractory and not have had carfilzomib within the past 6 months
