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 |
- 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.
- 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
- 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
- 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
- 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
