Avastin plus PC demonstrated an increase in OS with Avastin given until disease progression or unacceptable toxicity

In Study E4599, patients who were responding or had stable disease after 6 cycles of Avastin plus PC continued on Avastin alone until disease progression or unacceptable toxicity1,3

- In Study E4599, 53% of patients in the Avastin plus PC arm continued with Avastin alone, and 50% of these patients received more than 5 cycles of Avastin alone2

Bevacizumab is the only FDA-approved agent for first-line metastatic non-squamous NSCLC that has an NCCN category 1 recommendation for continuation maintenance (based on high-level evidence and uniform consensus)4

Important treatment considerations—Dose modifications
- There are no recommended dose reductions
- Discontinue Avastin in patients with
- Gastrointestinal (GI) perforations (GI perforations, fistula formation in the GI tract, intra-abdominal abscess)
- Fistula formation involving an internal organ
- Wound dehiscence and wound healing complications requiring medical intervention
- Serious hemorrhage (ie, requiring medical intervention)
- Severe arterial thromboembolic event (ATE)
- Hypertensive crisis or hypertensive encephalopathy
- Reversible posterior leukoencephalopathy syndrome (RPLS) (symptoms usually resolve or improve within days, although some patients have experienced ongoing neurologic sequelae)
- Nephrotic syndrome
- Temporarily suspend Avastin for at least 4 weeks prior to elective surgery, severe hypertension not controlled with medical management, moderate to severe proteinuria pending further evaluation, and severe infusion reactions
- The safety of resumption of Avastin therapy in patients that experienced RPLS, ATE, and moderate to severe proteinuria is unknown
Indication
Avastin is indicated for the first-line treatment of unresectable, locally advanced, recurrent or metastatic non–squamous non–small cell lung cancer in combination with carboplatin and paclitaxel.
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 NSCLC, grade 3–5 (nonhematologic) and grade 4–5 (hematologic) adverse events in Study E4599 occurring at a ≥2% higher incidence in Avastin-treated patients vs controls were neutropenia (27% vs 17%), fatigue (16% vs 13%), hypertension (8% vs 0.7%), infection without neutropenia (7% vs 3%), venous thrombus/embolism (5% vs 3%), febrile neutropenia (5% vs 2%), pneumonitis/pulmonary infiltrates (5% vs 3%), infection with grade 3 or 4 neutropenia (4% vs 2%), hyponatremia (4% vs 1%), headache (3% vs 1%), and proteinuria (3% vs 0%)
