LOTIS-2: Haematological and laboratory TEAEs were generally manageable and reversible1

Haematological TEAEs & Laboratory TEAEs
  • Haematological parameters tended to partially recover between ZYNLONTA cycles2
  • The most common Grade 3 or higher AEs were neutropenia, thrombocytopenia and increased GGT levels2
    • Increased GGT levels was not associated with any severe hepatic events2
  • Dose reductions due to ZYNLONTA AEs occurred in 8% of patients2
    • More than half of dose reductions (≥4%) were due to increased GGT levels2
  • Dose modifications or interruptions due to an AE occurred in 47% of patients3
    • AEs leading to dose delay in ≥5% of patients were neutropenia, thrombocytopenia and increased GGT levels3
  • Most patients (55%) were ≥65 years of age. No overall differences in safety or efficacy were observed between older (>65 years) and younger patients2

 

Dose delays were mostly short (<1 week) and enabled patients to continue with ZYNLONTA2
