Indication
Avastin is indicated for the treatment of glioblastoma as a single agent for adult patients with progressive disease following prior therapy. The effectiveness of Avastin in glioblastoma is based on an improvement in objective response rate. There are no data demonstrating an improvement in disease-related symptoms or increased survival with Avastin.
Durable Responses: BRAIN Study
For adult GBM patients with progressive disease following prior therapy: single-agent Avastin demonstrated clinically meaningful activity
Single-agent Avastin demonstrated an objective response for a clinically meaningful duration1,2

- CI=confidence interval.

- NCCN=National Comprehensive Cancer Network.
Boxed WARNINGS
- Gastrointestinal (GI) perforation
- Serious and sometimes fatal GI perforation occurs at a higher incidence (up to 2.4%) in Avastin-treated patients compared to controls. Discontinue Avastin for GI perforation
- Surgery and wound healing complications
- The incidence of wound healing and surgical complications, including serious and fatal complications, is increased in Avastin-treated patients
- Discontinue in patients with wound dehiscence. Discontinue at least 28 days prior to elective surgery
- Do not initiate Avastin for at least 28 days after surgery and until the surgical wound is fully healed
- Hemorrhage
- Severe or fatal hemorrhage, hemoptysis, GI bleeding, CNS hemorrhage, and vaginal bleeding are increased in Avastin-treated patients. Do not administer Avastin to patients with serious hemorrhage or recent hemoptysis
Response assessment based on WHO radiographic criteria and stable or decreasing steroid use in the BRAIN study1,4
- WHO=World Health Organization.

- Clinical assessments and MRI, using T1 and T2/FLAIR sequences, were independent review facility (IRF)-assessed by 2 different radiologists and an oncologist1,4

Boxed WARNINGS
- Gastrointestinal (GI) perforation
- Serious and sometimes fatal GI perforation occurs at a higher incidence in Avastin-treated patients compared to controls
- The incidences of GI perforation ranged from 0.3% to 2.4% across clinical studies
- Discontinue Avastin in patients with GI perforation
- Surgery and wound healing complications
- The incidence of wound healing and surgical complications, including serious and fatal complications, is increased in Avastin-treated patients
- Do not initiate Avastin for at least 28 days after surgery and until the surgical wound is fully healed. The appropriate interval between termination of Avastin and subsequent elective surgery required to reduce the risks of impaired wound healing/wound dehiscence has not been determined
- Discontinue Avastin at least 28 days prior to elective surgery and in patients with wound healing complications requiring medical intervention
- 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 Avastin. Across indications, the incidence of grade ≥3 hemorrhagic events among patients receiving Avastin ranged from 1.2% to 4.6%
- Do not administer Avastin to patients with serious hemorrhage or recent hemoptysis (≥1/2 tsp of red blood)
- Discontinue Avastin in patients with serious hemorrhage (ie, requiring medical intervention)
Additional serious adverse events
-
Additional serious and sometimes fatal adverse events with increased incidence in the Avastin-treated arm vs control included
- Non-GI fistula formation (≤0.3%)
- Arterial thromboembolic events (grade ≥3, 2.4%)
- Proteinuria including nephrotic syndrome (<1%)
-
Additional serious adverse events with increased incidence in the Avastin-treated arm vs control included
- Hypertension (grade 3–4, 5%–18%)
- Reversible posterior leukoencephalopathy syndrome (RPLS) (<0.1%)
- Infusion reactions with the first dose of Avastin were uncommon (<3%), and severe reactions occurred in 0.2% of patients
- Inform females of reproductive potential of the risk of ovarian failure prior to starting treatment with Avastin
Most common adverse events
-
Most common adverse reactions observed in Avastin patients at a rate >10% and at least twice the control arm rate were
- – Epistaxis
- – Headache
- – Hypertension
- – Rhinitis
- – Proteinuria
- – Taste alteration
- – Dry skin
- – Rectal hemorrhage
- – Lacrimation disorder
- – Back pain
- – Exfoliative dermatitis
- Across all studies, Avastin was discontinued in 8.4% to 21% of patients because of adverse reactions
Pregnancy warning
- Avastin may impair fertility
- Based on animal data, Avastin may cause fetal harm
- Advise patients of the potential risk to the fetus during and following Avastin and the need to continue adequate contraception for at least 6 months following the last dose of Avastin
- For nursing mothers, discontinue nursing or Avastin, taking into account the importance of Avastin to the mother
- In GBM Study AVF3708g, in patients receiving Avastin alone, the most frequently reported adverse events were infection (55%), fatigue (45%), headache (37%), hypertension (30%), epistaxis (19%), and diarrhea (21%). Of these, the incidence of grade ≥3 adverse events was infection (10%), fatigue (4%), headache (4%), hypertension (8%), and diarrhea (1%). Two deaths were possibly related to Avastin: 1 retroperitoneal hemorrhage and 1 neutropenic infection
- In GBM patients receiving Avastin alone or Avastin plus irinotecan,a the incidences of Avastin-related adverse events (grade 1–4) were bleeding/hemorrhage (40%), epistaxis (26%), CNS hemorrhage (5%), hypertension (32%), venous thromboembolic events (8%), arterial thromboembolic events (6%), wound healing complications (6%), proteinuria (4%), GI perforation (2%), and RPLS (1%). The incidences of grade 3–5 events in these 163 patients were bleeding/hemorrhage (2%), CNS hemorrhage (1%), hypertension (5%), venous thromboembolic events (7%), arterial thromboembolic events (3%), wound healing complications (3%), proteinuria (1%), and GI perforation (2%). Intracranial hemorrhage occurred in 8 of 163 patients; 2 patients had grade 3–4 hemorrhage
- aAvastin is not approved for use in combination with irinotecan.
