• Specific Exclusion Criteria for R/R AML: Active graft-versus-host-disease requiring immunosuppressive treatment. Any immunosuppressive medication (eg, calcineurin inhibitors) must be stopped ≥4 weeks prior to the first dose of GEN3014. Please refer to the protocol section 5.2.2 for the full list of Exclusion criteria for the Expansion Part B (Randomized H2H).

• Specific Exclusion Criteria for RRMM: Autologous HSCT within 3 months of the first dose of GEN3014.
• Specific Exclusion Criteria for R/R AML: <5% blasts in blood or bone marrow at Screening.
• Specific Exclusion Criteria for R/R AML: Allogenic HSCT within 3 months of the first dose of GEN3014
• Primary central nervous system (CNS) tumor or known CNS involvement at Screening.

• Must be at least 18 years of age.
  • Specific Inclusion Criteria for RRMM: 10. Must have documented multiple myeloma as defined by the criteria below and have evidence of disease progression on the most recent prior treatment regimen based on IMWG criteria: • Prior documentation of monoclonal plasma cells in the bone marrow ≥ 10% or presence of a biopsy-proven plasmacytoma and • Measurable disease at baseline as defined by any of the following: - IgG, IgA, IgD, or IgM myeloma: Serum M-protein level ≥0.5 g/dL (≥ 5 g/L) or urine M-protein level ≥200 mg/24 hours; or - Light chain myeloma: Serum Ig free light chain (FLC) ≥10 mg/dL and abnormal serum Ig kappa lambda FLC ratio. Participants with RRMM must have exhausted standard therapies, at the investigator’s discretion.
• For anti-CD38 mAb-naive RRMM subjects: Subject received at least 3 prior lines of therapy including a PI and an IMiD in any order, or is double refractory to a PI and an IMiD; or subject received ≥ 2 prior lines of therapy if 1 of those lines included a combination of PI and IMiD. Note: Subjects should not have received any anti-CD38 antibody.
• For anti-CD38 mAb-treated RRMM participants: Participant has received at least 2 prior lines of therapy and must have discontinued daratumumab or isatuximab for at least 4 weeks prior to the first dose of GEN3014. Note: Participants should not have received any other anti-CD38 antibody except daratumumab or isatuximab.
• Potassium level ≥3.0 mEq/L (≥3.0 mmol/L); and corrected serum calcium ≤14.0 mg/dL (≤3.5 mmol/L) or free ionized calcium ≤6.5 mg/dL (≤1.6 mmol/L).
  • Specific Inclusion Criteria for R/R AML: 14. Relapsed or refractory AML, both de novo or secondary; must have failed all conventional therapy. Acute promyelocytic leukemia (APL) is excluded from this trial. Note: Relapse is defined by BM blasts ≥5% in patients who have been in complete remission (CR) previously, or reappearance of blasts in the blood, or development of extramedullary AML. Refractory is defined as not being able to achieve a CR after the initial therapy.
  • Specific Inclusion Criteria for R/R AML: 15. Subject with relapsed AML who received at least 2 prior therapies for AML with the exception of hydroxyurea.
  • Specific Inclusion Criteria for R/R AML: 16. Subject with refractory AML who received at least 1 prior line of therapy for AML with the exception of hydroxyurea.
  • Specific Inclusion Criteria for R/R AML: 17. Subject's life expectancy at Screening is judged to be at least 3 months.
