Lori J.

There were 6 treatment-related deaths on the study.

  • In the SELECT trial, patients had to have disease progression at time of entry to be eligible. These patients had bad thyroid cancer that was progressive over a short period of time.
  • The side effects of lenvatinib are similar to those with other VEGFR multikinase inhibitors: hypertension, diarrhea, decreased appetite, weight loss, and rash.
  • There were 6 treatment-related deaths on the study: 2 were known toxicities of this class of drugs and 4 patients died due to generalized deterioration of their health.
  • In the context of this patient population, deaths are not uncommon with effective oncology drugs.
