Brief Summary:
A phase 1/2a, first-in-human trial to evaluate the safety and tolerability of LAVA-051 in patients with relapsed or refractory Chronic Lymphocytic Leukemia (CLL), Multiple Myeloma (MM), or Acute Myeloid Leukemia (AML).

Condition or disease Intervention/treatment Phase
Chronic Lymphocytic Leukemia Multiple Myeloma Acute Myeloid Leukemia Biological: LAVA-051 Phase 1 Phase 2

Detailed Description:
An open-label, phase 1/2a dose escalation trial with disease-specific expansion cohorts to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary anti-tumor activity of LAVA-051 in patients with relapsed or refractory CLL, MM, or AML.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 102 participants
Allocation: N/A
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/2a Open-label Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, Immunogenicity and Antitumor Activity of LAVA-051 in Patients With Relapsed or Refractory CLL, MM, or AML
Actual Study Start Date : July 12, 2021
Estimated Primary Completion Date : September 24, 2024
Estimated Study Completion Date : December 30, 2024

Arm Intervention/treatment
Experimental: LAVA-051

In part 1 (dose escalation) LAVA-051 will be administered via intravenous infusion with dose escalation

In part 2 (dose expansion) patients will receive LAVA-051 at the dose established in part 1 of the study

Biological: LAVA-051
In part 1 and part 2, LAVA-051 will be administered via intravenous infusion

Primary Outcome Measures :
  1. Part 1 & Part 2 - Frequency and severity of AEs: [ Time Frame: Approximately 6 months ]
    Frequency, severity, and grading of Adverse Events using the Common Terminology Criteria and grading for Adverse Events (CTCAE) v5.0. CRS will be evaluated using the ASTCT.

  2. Part 1 - Frequency and type of DLT [ Time Frame: First 28 days of treatment ]
    A DLT is defined as an adverse event that is unrelated to disease progression, intercurrent illness, or concomitant medications and is occurring during the first 28 days of treatment. These events will be classified according to the CTCAE v5.0; CRS will be evaluated according to the ASTCT consensus criteria

Secondary Outcome Measures :
  1. Part 1 & Part 2: Number of participants with an antitumor response [ Time Frame: Approximately 6 months ]
    Antitumor response for CLL per iwCLL guidelines, MM per IMWG-based response criteria, and AML per ELN criteria

  2. Part 1 & Part 2: Pharmacokinetics of LAVA-051, area under the plasma concentration versus time curve (AUC) [ Time Frame: Approximately 6 months ]
    Area under the plasma concentration versus time curve (AUC) of LAVA-051 will be assessed in all patients treated with LAVA-051

  3. Part 1 & Part 2: Incidence and prevalence anti-LAVA-051 antibodies [ Time Frame: Approximately 6 months ]
    Development of antibodies (anti-drug antibodies) to LAVA-051 will be evaluated
