Study Description

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. Parts A and B will consist of 3 periods: Screening, Treatment, and Follow-up.

  • Condition or Disease:Lymphoma, Non-Hodgkin
  • Intervention/Treatment: Drug: CC-96673
  • Phase: Phase 1

Detailed Description

Outcome Measures

  • Primary Outcome Measures: 1. Incidence of Adverse Events (AEs) [ Time Frame: 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.
  • 2. Dose-limiting toxicity (DLT) [ Time Frame: Up to approximately 18 months ]
    Number of participants with a DLT
  • 3. Maximum tolerated dose (MTD) [ Time Frame: 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: 1. Overall response rate (ORR) [ Time Frame: Up to 2 years after study treatment ]
    Is defined as the percent of participants whose best response is CR or PR
  • 2. Time to response (TTR) [ Time Frame: Up to 2 years after study treatment ]
    Is defined as the time from the first dose of CC-96673 to tumor response
  • 3. Duration of response (DOR) [ Time Frame: Up to 2 years after study treatment ]
    Is defined as the time from tumor response to progression/death
  • 4. Progression free survival (PFS) [ Time Frame: 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
  • 5. Pharmacokinetics - Cmax [ Time Frame: Up to 24 Months ]
    Maximum observed serum concentration of drug
  • 6. Pharmacokinetics - Cmin [ Time Frame: Up to 24 Months ]
    Observed serum concentration of drug at the end of a dosing interval
  • 7. Pharmacokinetics - AUC [ Time Frame: Up to 24 Months ]
    Area under the serum concentration-time curve
  • 8. Pharmacokinetics - tmax [ Time Frame: Up to 24 Months ]
    Time of maximum observed serum concentration
  • 9. Pharmacokinetics - t1/2 [ Time Frame: Up to 24 Months ]
    Terminal half-life
  • 10. Pharmacokinetics - CL [ Time Frame: Up to 24 Months ]
    Total body clearance
  • 11. Pharmacokinetics - Vss [ Time Frame: Up to 24 Months ]
    Volume of distribution at steady-state
  • 12. Pharmacokinetics - Accumulation ratio [ Time Frame: Up to 24 Months ]
    Accumulation ratio
  • 13. Presence of Anti-drug antibodies (ADA) [ Time Frame: Up to 24 Months ]
    Determined by using a validated bridging immunoassay with electrochemiluminescence detection
  • 14. Frequency of Anti-drug antibodies (ADA) [ Time Frame: Up to 24 Months ]
    Determined by using a validated bridging immunoassay with electrochemiluminescence detection

Eligibility Criteria

  • Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
  • Sexes Eligible for Study: All
  • Accepts Healthy Volunteers: No


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 tumor accessible for biopsies. 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.

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.
