Clinical Trial 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

Type Measure Description Time frame Safety issue
Primary Percentage of Participants with =1 Adverse Event (AE) [cohort C and D] 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. Up to approximately 57 months
Primary Percentage of Participants Discontinuing from Study Therapy Due to AE (cohort C and D) 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. Up to approximately 57 months
Primary Percentage of Participants with Dose-Limiting Toxicity (DLT) [cohort C] 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. Up to approximately 57 months
Primary 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] 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. Up to approximately 57 months
Primary ORR per Lugano Response Criteria as Assessed by Investigator (cohort C) 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. Up to approximately 57 months
Primary ORR per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria as Assessed by Investigator ORR, defined as the percentage of participants who achieve a CR or PR per iwCLL criteria as assessed by investigator will be reported. Up to approximately 57 months
Secondary Duration of Response (DOR) per Lugano Response Criteria as Assessed by BICR (cohorts A, B, D (FL), and E) 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. Up to approximately 57 months
Secondary DOR per Lugano Response Criteria as Assessed by Investigator (cohort C) 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. Up to approximately 57 months
Secondary DOR per iwCLL Criteria as Assessed by Investigator (cohorts D [CLL] and F) 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. Up to approximately 57 months
Secondary Percentage of Participants with =1 AE (cohorts A, B, E, and F) 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. Up to approximately 57 months
Secondary Percentage of Participants Discontinuing from Study Therapy Due to AE (cohorts A, B, E, and F) 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. Up to approximately 57 months
