NCT03833180

Brief Summary

The purpose of this study is to evaluate the safety, pharmacokinetics, immunogenicity, and efficacy of zilovertamab vedotin given intravenously (IV) across a range of dose levels in participants with previously treated hematological cancers including acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), Burkitt lymphoma (BL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), lymphoplasmacytoid lymphoma/Waldenström macroglobulinemia (LPL/WM), mantle cell lymphoma (MCL), marginal zone lymphoma (MZL), Richter transformation lymphoma (RTL), and T-cell non-Hodgkin lymphoma (NHL).

Outcome Measures

Primary Outcomes (2)

  • Maximum tolerated dose (MTD) of zilovertamab vedotin

    Participants will receive zilovertamab vedotin according to Schedule 1, 2, or 3. The MTD will be determined by the number of participants who experience a dose limiting toxicity (DLT). The MTD will be defined as the highest tested dose level at which ≥6 participants have been treated and which is associated with a Cycle 1 DLT in ≤17% of the participants.

    Cycle 1 (Up to 21 Days)

  • Recommended Dosing Regimen (RDR)

    Selection of the RDR will be based on consideration of short- and long-term safety information together with available pharmacokinetic, pharmacodynamic, and efficacy data. The RDR may be the MTD or may be a lower dose within the tolerable dose range.

    Cycle 1 (Up to 21 Days)

Secondary Outcomes (37)

  • Average number of zilovertamab vedotin infusions administered

    Up to 5 months

  • Number of participants with a treatment-emergent adverse event (TEAE)

    Up to approximately 3.5 years

  • Number of participants with a DLT

    Cycle 1 (Up to 21 Days)

  • Number of participants with a serious adverse event (SAE)

    Up to approximately 3.5 years

  • Number of participants with an adverse event of special interest (AESI)

    Up to approximately 3.5 years

  • +32 more secondary outcomes

  • Uncontrolled ongoing systemic bacterial, fungal, or viral infection.
  • Known diagnosis of liver cirrhosis.

  • Prior solid organ transplantation.
  • Major surgery within 4 weeks before the start of study therapy.
  • Prior therapy with a receptor tyrosine kinase-like orphan receptor 1 (ROR1)-directed therapy.
  • Has ongoing corticosteroid therapy (exceeding 30 mg daily of prednisone equivalent). Prednisone equivalent dosing must have been stable for at least 4 weeks prior to Cycle 1 Day 1 (C1D1). If corticosteroid treatment is required for lymphoma symptom control prior to C1D1, up to 100 mg per day of prednisone equivalent can be given for up to 5 days. In that case, all tumor assessments must have been completed prior to the start of corticosteroid treatment.
