  1. Data are number of patients (%). This table included all grade treatment-related adverse events occurring in at least 10% of patients and all grade 3–5 events
  2. §One patient developed volvulus during treatment and resulted in death, which was deemed uncertainly related to geptanolimab treatment by investigator
  3. #The death was deemed uncertainly related to treatment
  4. *Treatment-related adverse events were defined as an adverse event related, possibly related or uncertainly related to treatment, as assessed by the investigator
