A Dose Finding Study of CC-96673 in Participants With Relapsed or Refractory Non-Hodgkin's Lymphoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this Phase 1 study is to evaluate the safety and tolerability of CC-96673 in adult participants with Relapsed or Refractory Non-Hodgkin's Lymphoma (R/R NHL). The study will be conducted in 2 parts: Part A, monotherapy dose escalation and Part B, monotherapy dose expansion.

Eligibility Criteria
-----------------
Inclusion Criteria: Participants must satisfy the following criteria to be enrolled in the study: Participant (male or female) is ≥ 18 years of age at the time of signing the informed consent form (ICF). Participant must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted. Participant is willing and able to adhere to the study visit schedule and other protocol requirements. Participant must have a history of NHL that has relapsed or progressed. Participant has an ECOG PS of 0 or 1. Participants must have acceptable laboratory values as specified in the protocol. Exclusion Criteria: Participant has cancer with symptomatic central nervous system (CNS) involvement Participant is on chronic systemic immunosuppressive therapy or corticosteroids or subjects with clinically significant graft-versus-host disease (GVHD). Intranasal, inhaled, topical, or local corticosteroid injections, or steroids as premedication for hypersensitivity reactions are exceptions to this criterion. Inadequate cardiac function or significant cardiovascular disease Participant has received prior investigational therapy directed at CD47 or SIRPα. Participant had major surgery ≤ 2 weeks prior to starting CC-96673. Participant is a pregnant or lactating female or intends to become pregnant during participation of the study. Participant has known active human immunodeficiency virus (HIV) infection. Participant has active hepatitis B or C (HBV/HCV) infection. Ongoing treatment with chronic, therapeutic dosing of anti-coagulants. History of autoimmune hemolytic anemia or autoimmune thrombocytopenia. History of concurrent second cancers requiring active, ongoing systemic treatment. Participant has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study. Participant has active, uncontrolled, or suspected infection. Other protocol defined inclusion/exclusion criteria could apply.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of Adverse Events (AEs) | 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. | From enrollment until at least 28 days after completion of study treatment | 
| Dose-limiting toxicity (DLT) | Number of participants with a DLT | Up to approximately 18 months | 
| Maximum tolerated dose (MTD) | Is defined as the dose level that can be given such that the estimated DLT probability is closest to approximately 30%. | Up to approximately 18 months | 

Secondary Outcome Measures

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