IMPORTANT SAFETY INFORMATION AND INDICATION
IMPORTANT SAFETY INFORMATION AND INDICATIONS
Warnings and Precautions
- Gastrointestinal Perforations and Fistulae. Serious and sometimes fatal gastrointestinal perforation occurred at a higher incidence in patients receiving bevacizumab products compared to patients receiving chemotherapy. The incidence ranged from 0.3% to 3% across clinical studies. Non-GI fistulae incidence ranged from <1% to 1.8%, and was highest in patients with cervical cancer. Avoid ZIRABEV in patients with ovarian cancer who have evidence of recto-sigmoid involvement by pelvic examination or bowel involvement on CT scan or clinical symptoms of bowel obstruction. Discontinue for gastrointestinal perforations, tracheoesophageal fistula, grade 4 fistula, or fistula formation involving any internal organ
- Surgery and Wound Healing Complications. The incidence of wound healing and surgical complications, including serious and fatal complications, is increased in bevacizumab-treated patients. In patients who experience wound healing complications during ZIRABEV treatment, withhold ZIRABEV until adequate wound healing. Withhold for at least 28 days prior to elective surgery. Do not administer for at least 28 days following major surgery and until adequate wound healing. The safety of resumption of bevacizumab products after resolution of wound healing complications has not been established. Discontinue for wound healing complications of necrotizing fasciitis
- Hemorrhage. Severe or fatal hemorrhage, including hemoptysis, GI bleeding, hematemesis, central nervous system hemorrhage, epistaxis, and vaginal bleeding occurred up to 5-fold more frequently in patients receiving bevacizumab. In clinical studies, the incidence of grade ≥3 hemorrhagic events among patients receiving bevacizumab ranged from 0.4% to 7%. Do not administer ZIRABEV to patients with serious hemorrhage or a recent history of hemoptysis (≥1/2 tsp of red blood). Discontinue ZIRABEV in patients who develop grade 3-4 hemorrhage
- Additional serious and sometimes fatal adverse events with increased incidence in the bevacizumab-treated arm vs chemotherapy arm included:
- Arterial thromboembolic events (ATE) (grade ≥3, 5%, highest in patients with GBM). Discontinue in patients who develop a severe ATE
-
Renal injury and proteinuria. Monitor proteinuria during ZIRABEV therapy. Patients with a 2+ or greater urine dipstick reading should undergo 24-hour urine collection. Withhold for proteinuria ≥2 grams per 24 hours and resume when less than 2 grams per 24 hours. Discontinue in patients who develop nephrotic syndrome
- Grade 3-4 proteinuria ranged from 0.7% to 7% in clinical studies
- Nephrotic syndrome (<1%)
- Additional serious adverse events with increased incidence in the bevacizumab-treated arm vs chemotherapy arm included:
- Venous thromboembolism events (VTE) (grade ≥3, 11% seen in Study GOG-0240). Discontinue ZIRABEV in patients with a grade 4 VTE, including pulmonary embolism
- Hypertension (grade 3-4, 5%-18%). Monitor blood pressure during treatment and, for ZIRABEV-associated hypertension, continue monitoring after discontinuation. Withhold for severe hypertension. Discontinue for hypertensive crisis or hypertensive encephalopathy
- Posterior reversible encephalopathy syndrome (PRES) (<0.5%). Discontinue ZIRABEV in patients who develop PRES. Symptoms usually resolve or improve within days after discontinuing bevacizumab products, although some patients have experienced ongoing neurologic sequelae
- Congestive heart failure (CHF) (grade ≥3 left ventricular dysfunction, 1%). Discontinue ZIRABEV in patients who develop CHF
- Infusion-related reactions. Infusion-related reactions with the first dose of bevacizumab occurred in <3% of patients, and severe reactions occurred in 0.4% of patients. Decrease the rate of infusion for mild infusion-related reactions. Interrupt the infusion in patients with clinically significant infusion-related reactions and consider resuming at a slower rate following resolution. Discontinue in patients who develop a severe infusion-related reaction and administer appropriate medical therapy
- Ovarian failure. Inform females of reproductive potential of the risk of ovarian failure prior to initiating treatment with ZIRABEV
Pregnancy Warning
- Based on the mechanism of action and animal studies, bevacizumab products may cause fetal harm
- Advise female patients that bevacizumab products may cause fetal harm and to inform their health care provider of a known or suspected pregnancy
- Advise females of reproductive potential to use effective contraception during treatment with ZIRABEV and for 6 months after the last dose of ZIRABEV
- Advise nursing women that breastfeeding is not recommended during treatment with ZIRABEV and for 6 months following their last dose of treatment
- Bevacizumab products may impair fertility
Most Common Adverse Events
- Across studies, the most common adverse reactions observed in bevacizumab patients at a rate >10% were:
- Epistaxis, headache, hypertension, rhinitis, proteinuria, taste alteration, dry skin, hemorrhage, lacrimation disorder, back pain, exfoliative dermatitis
- Across all studies, bevacizumab was discontinued in 8% to 22% of patients because of adverse reactions
