5. Pregnant or breastfeeding females.
6. Active, unstable cardiovascular function, as indicated by the presence of symptomatic ischemia, or Uncontrolled clinically significant conduction abnormalities (eg, patients with ventricular tachycardia on anti-arrhythmics are excluded; patients with first degree atrioventricular block or asymptomatic left anterior fascicular block/right bundle branch block will not be excluded), or Congestive heart failure of New York Heart Association Class ≥3 or known left ventricular ejection fraction <40%, or Myocardial infarction within 3 months prior to C1D1.
7. Subjects with active hepatitis B virus (Hep B) are allowed if antiviral therapy for hepatitis B has been given for >8 weeks and viral load is <100 IU/ml prior to first dose of trial treatment.

Subjects with Human Immunodeficiency Virus (HIV) who have cluster of differentiation 4-positive (CD4+) T-cell counts ≥ 350 cells/µL and no history of AIDS-defining opportunistic infections in the last year are allowed.
8. Any active gastrointestinal dysfunction interfering with the patient's ability to swallow tablets, or any active gastrointestinal dysfunction that could interfere with absorption of study treatment.
9. Inability or unwillingness to take supportive medications such as anti-nausea and anti-anorexia agents as recommended by the National Comprehensive Cancer Network® (NCCN) Clinical Practice Guidelines in Oncology (CPGO) (https://www.nccn.org/guidelines/category_3) for antiemesis and anorexia/cachexia (palliative care).
10. Any active, serious psychiatric, medical, or other conditions/situations that, in the opinion of the Investigator, could interfere with treatment, compliance, or the ability to give informed consent.
11. Contraindication to any of the required concomitant drugs or supportive treatments.
12. Patients unwilling or unable to comply with the protocol or known mental or physical illness that would interfere with cooperation with the requirements of the trial or confound the results or interpretation of the results of the trial and, in the opinion of the treating investigator, would make the patient inappropriate for entry into the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Fraction of Participants Achieving Overall Response	Overall response rate (ORR) will be reported as the fraction of participants achieving either complete response (CR) or partial response (ORR = CR + PR) to study treatment. Response to therapy will be assessed by treating physician using International Myeloma Working Group 2016 response criteria.	Up to 3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	Overall survival (OS) will be defined as the time elapsed from the start of treatment until death. For surviving patients, follow-up will be censored at the date of last contact.	Up to 3 years
Duration of Response (DoR)	Duration of response is defined as the elapsed time from date of partial response (PR) or better to the date of progressive disease (PD) or death, whichever is first.	Up to 3 years
Minimal Residual Disease Negative Complete Response Rate	Minimum residual disease negative (MRD negative) complete response (CR) rate will be reported as the fraction of participants achieving CR who show less than one myeloma cell per million bone marrow cells after protocol therapy. Response to therapy will be assessed using International Myeloma Working Group 2016 response criteria.	Up to 3 years
Progression-Free Survival (PFS)	Progression-free survival (PFS) will be defined as the time elapsed from the start of treatment to the date of documented progression or death, whichever comes first. For surviving participants without progression who begin alternative treatment, PFS will be censored at the last date of documented progression-free status prior to starting alternative treatment. Similarly, losses to follow up will be censored at the last date of documented progression-free status.	Up to 3 years
Rate of Treatment-Emergent Adverse Events	Safety and tolerability of assigned protocol treatment will be reported as the rate of treatment-related toxicity, including serious adverse events (SAEs), grade 3 or higher adverse events, and all-grade adverse events (AEs), in study participants using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, as assessed by treating physician.	Up to 10 months
