Brief Summary:

The purpose of this study is to assess the safety and tolerability of zilovertamab vedotin as monotherapy and in combination in participants with select B-cell lymphomas including mantle cell lymphoma (MCL), Richter's transformation lymphoma (RTL), follicular lymphoma (FL), and chronic lymphocytic leukemia (CLL). This study will also evaluate zilovertamab vedotin as monotherapy and in combination with respect to objective response rate.

  • Cohort A: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 2 prior systemic therapies including a Bruton's tyrosine kinase inhibition/inhibitor (BTKi), and post therapy chimeric antigen receptor T (CAR-T) cell therapy or ineligible for CAR-T cell therapy
  • Cohort B: Participants with relapsed or refractory RT disease after at least 1 prior systemic therapy
  • Cohort C: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 1 prior systemic therapy and no prior exposure to a non-covalent BTKi
  • Cohort D: Participants with relapsed or refractory FL and CLL relapsed or refractory disease after at least 2 prior systemic therapies and have no other available therapy
  • Cohort E: Participants with relapsed or refractory FL after at least 2 prior systemic therapies and have no other available therapy
  • Cohort F: Participants with relapsed or refractory CLL after at least 2 prior systemic therapies and have no other available therapy

The primary study hypothesis is that zilovertamab vedotin monotherapy has an increased Objective Response Rate (ORR) per Lugano Response Criteria as assessed by blinded independent central review (BICR).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants with ≥1 Adverse Event (AE) [cohort C and D] [ Time Frame: Up to approximately 57 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants with MCL, FL, and CLL who experienced an AE will be reported.

  2. Percentage of Participants Discontinuing from Study Therapy Due to AE (cohort C and D) [ Time Frame: Up to approximately 57 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants with MCL, FL, and CLL who discontinued study treatment due to an AE will be reported.

  3. Percentage of Participants with Dose-Limiting Toxicity (DLT) [cohort C] [ Time Frame: Up to approximately 57 months ]
    The Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0 will be used to grade the severity of AEs. DLTs for participants with MCL as assessed by investigator will be reported.

  4. Objective Response Rate (ORR) per Lugano Response Criteria as Assessed by Blinded Independent Central Review (BICR) [cohorts A, B, E and FL participants in D] [ Time Frame: Up to approximately 57 months ]
    ORR, defined as the percentage of participants who achieve a complete response (CR) or partial response (PR) per Lugano Response Criteria as assessed by BICR will be reported.

  5. ORR per Lugano Response Criteria as Assessed by Investigator (cohort C) [ Time Frame: Up to approximately 57 months ]
    ORR, defined as the percentage of participants who achieve a complete response (CR) or partial response (PR) per Lugano Response Criteria as assessed by investigator will be reported.

  6. ORR per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria as Assessed by Investigator [ Time Frame: Up to approximately 57 months ]
    ORR, defined as the percentage of participants who achieve a CR or PR per iwCLL criteria as assessed by investigator will be reported.


Secondary Outcome Measures :
  1. Duration of Response (DOR) per Lugano Response Criteria as Assessed by BICR (cohorts A, B, D (FL), and E) [ Time Frame: Up to approximately 57 months ]
    DOR, defined as the time from the first documented evidence of CR or PR per Lugano Response Criteria as assessed by BICR, until disease progression or death due to any cause, whichever occurs first, will be reported.

  2. DOR per Lugano Response Criteria as Assessed by Investigator (cohort C) [ Time Frame: Up to approximately 57 months ]
    DOR, defined as the time from the first documented evidence of CR or PR per Lugano Response Criteria as assessed by investigator, until disease progression or death due to any cause, whichever occurs first, will be reported.

  3. DOR per iwCLL Criteria as Assessed by Investigator (cohorts D [CLL] and F) [ Time Frame: Up to approximately 57 months ]
    DOR, defined as the time from the first documented evidence of CR or PR per iwCLL criteria as assessed by investigator, until disease progression or death due to any cause, whichever occurs first, will be reported.

  4. Percentage of Participants with ≥1 AE (cohorts A, B, E, and F) [ Time Frame: Up to approximately 57 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants with MCL, RTL, FL, and CLL who experienced an AE will be reported.

  5. Percentage of Participants Discontinuing from Study Therapy Due to AE (cohorts A, B, E, and F) [ Time Frame: Up to approximately 57 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The percentage of participants with MCL, RTL, FL, and CLL who discontinued study treatment due to an AE will be reported.
