7. Participant has known active human immunodeficiency virus (HIV) infection.
8. Participant has active hepatitis B or C (HBV/HCV) infection.
9. Ongoing treatment with chronic, therapeutic dosing of anti-coagulants.
10. History of autoimmune hemolytic anemia or autoimmune thrombocytopenia.
11. History of concurrent second cancers requiring active, ongoing systemic treatment.
12. Participant has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study.
13. Participant has active, uncontrolled, or suspected infection. Other protocol defined inclusion/exclusion criteria could apply.

Arm && Interventions

Group	Intervention	Description
Administration of CC-96673	CC-96673	CC-96673 will be administered on a once weekly (Q1W) or once every 2 weeks (Q2W) schedule

Primary Outcome Measures

Name	Time	Method
Incidence of Adverse Events (AEs)	From enrollment until at least 28 days after completion of study treatment	An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a participant during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values, regardless of etiology. Any worsening (ie, any clinically significant adverse change in the frequency or intensity of a pre-existing condition) should be considered an AE.
Dose-limiting toxicity (DLT)	Up to approximately 18 months	Number of participants with a DLT
Maximum tolerated dose (MTD)	Up to approximately 18 months	Is defined as the dose level that can be given such that the estimated DLT probability is closest to approximately 30%.

Secondary Outcome Measures

Name	Time	Method
Overall response rate (ORR)	Up to 2 years after study treatment	Is defined as the percent of participants whose best response is CR or PR
Time to response (TTR)	Up to 2 years after study treatment	Is defined as the time from the first dose of CC-96673 to tumor response
Duration of response (DOR)	Up to 2 years after study treatment	Is defined as the time from tumor response to progression/death
Progression free survival (PFS)	Up to 2 years after study treatment	Is defined as the time from the first dose of CC-96673 to the first occurrence of disease progression or death from any cause
Pharmacokinetics - Cmax	Up to 24 Months	Maximum observed serum concentration of drug
Pharmacokinetics - AUC	Up to 24 Months	Area under the serum concentration-time curve
Pharmacokinetics - tmax	Up to 24 Months	Time of maximum observed serum concentration
Incidence of laboratory-reported positive responses of anti-CC-96673 antibodies	Up to 24 Months
