LENVIMA® IMPORTANT SAFETY INFORMATION

LENVIMA® (lenvatinib capsules) is indicated:

  • Renal Cell Carcinoma (RCC) in combination with pembrolizumab, for the treatment of adult patients with advanced (not amenable to curative surgery or radiation) or metastatic RCC with no prior systemic therapy for metastatic RCC.
  • Endometrial Carcinoma (EC) in combination with pembrolizumab, for the treatment of adult patients with advanced endometrial carcinoma that is not microsatellite instability high (MSI-H) or mismatch repair deficient (dMMR), who have disease progression following prior platinum-based systemic therapy, and are not candidates for curative surgery or radiation.

 

Clinical use:

  • The safety and efficacy of LENVIMA® have not been established in patients < 18 years of age

Most serious warnings & precautions:

Hypertension and its complications, including fatal artery dissection

Cardiovascular: Cardiac failure, including fatal cases

Arterial thromboembolism (ATE), including fatal cases

Gastrointestinal perforation and fistula formation, including reactions leading to death

Hepatic/Biliary/Pancreatic: Hepatotoxicity/hepatic failure, including fatal cases

Renal: Renal failure and impairment, including fatal cases. The primary risk factor identified was dehydration/hypovolemia due to diarrhea and vomiting

Hematologic: Hemorrhage, including fatal cases

Neurologic: Posterior reversible encephalopathy syndrome (PRES)

Other relevant warnings and precautions:

  • Prior anticancer treatments
  • QTc prolongation; correct electrolyte abnormalities in all patients. Avoid use with electrolyte-disrupting drugs
