Gastrointestinal

All three TE fistulas occurred during the bevacizumab maintenance phase of the study in the context of persistent esophagitis. Additionally, six other cases of TE fistula have been reported in other lung and esophageal cancer studies using bevacizumab and chemotherapy alone or with concurrent radiation treatment.

The incidence of gastrointestinal perforation (gastrointestinal perforation, fistula formation, and/or intraabdominal abscess) in patients with colorectal cancer and in patients with non-small cell lung cancer (NSCLC) receiving bevacizumab was 2.4% and 0.9%, respectively.^[Ref]

Very common (10% or more): Abdominal pain (up to 61%), vomiting (up to 52%), anorexia (up to 43%), constipation (up to 40%), diarrhea (up to 34%), stomatitis (up to 32%), dyspepsia (up to 24%), gastrointestinal hemorrhage (up to 24%), flatulence (up to 19%)

Common (1% to 10%): Dry mouth, colitis, constipation, nausea

Very rare (less than 0.01%): TE fistula, upper aerodigestive tract hemorrhage

Frequency not reported: Intestinal obstruction, intestinal necrosis, mesenteric venous occlusion, ileus, anastomotic ulceration, gastrointestinal perforation and wound dehiscence (complicated by intra-abdominal abscesses), tracheoesophageal fistulae^[Ref]

Cardiovascular

Risk factors for the development of arterial thromboembolic events have included a history of arterial thromboembolism prior to bevacizumab exposure, age 65 years and above, and bevacizumab therapy. These events have occurred at a higher rate in these high-risk groups.

In one study, the rate of congestive heart failure (defined as NCI-CTC grade 3 and 4) in the bevacizumab plus paclitaxel arm was 2.2% versus 0.3% in the control arm. Among patients receiving anthracyclines, the rate of CHF was 3.8% for bevacizumab treated patients and 0.6% for patients receiving paclitaxel alone. Congestive heart failure occurred in six of 44 (14%) patients with relapsed acute leukemia (a non-FDA approved indication) receiving bevacizumab and concurrent anthracyclines in a single arm study. The safety of continuation or resumption of bevacizumab in patients with cardiac dysfunction has not been studied.^[Ref]

Very common (10% or more): Hypertension (up to 34%), hypotension (up to 15%)

Common (1% to 10%): Deep vein thrombosis, congestive heart failure

Frequency not reported: Arterial thromboembolic events (including cerebrovascular accident (stroke), myocardial infarction, transient ischemic attack, angina), fatal arterial thrombotic events, cerebral ischemia, supraventricular tachycardia, both serious and non-serious hemorrhagic events^[Ref]

Nervous system

Very common (10% or more): Dizziness (up to 26%), sensory neuropathy (24%)

Common (1% to 10%): Confusion, abnormal gait, CNS hemorrhage, cerebrovascular ischemia

Rare (less than 0.1%): Brain-capillary leak syndrome (reversible posterior hyponatremia

hypertensive encephalopathy

Frequency not reported: Dysgeusia^[Ref]

RPLS is a neurological disorder associated with hypertension, fluid retention, and cytotoxic effects of immunosuppressive drugs on the vascular endothelium. The syndrome can present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present, but is not necessary for diagnosis. The onset of symptoms has been reported to occur from sixteen hours to one year after initiation of bevacizumab. Magnetic resonance imaging is necessary to confirm the diagnosis of RPLS.^[Ref]

Hematologic

Very common (10% or more): Leukopenia (37%), neutropenia (21%)

Common (1% to 10%): Thrombocytopenia

Frequency not reported: Hemorrhagic events, pancytopenia, febrile neutropenia, decreased hemoglobin, anemia, prothrombin time prolongations, infection with severe neutropenia^[Ref]

Frequency not reported: Pulmonary hypertension, fatal pulmonary hemorrhage, nasal septum perforation

Common (1% to 10%): Voice alteration^[Ref]

Patients with recent hemoptysis (greater than or equal to 1/2 tsp of red blood) should not receive bevacizumab.

In study 6, four of 13 (31%) bevacizumab-treated patients with squamous cell histology and two of 53 (4%) bevacizumab-treated patients with histology other than squamous cell, experienced serious or fatal pulmonary hemorrhage as compared to none of the 32 (0%) patients receiving chemotherapy alone. In study 5, the rate of pulmonary hemorrhage requiring medical intervention for the paclitaxel, carboplatin, plus bevacizumab arm was 2.3% (10 of 427) compared to 0.5% (2 of 441) for the paclitaxel plus carboplatin alone arm. There were seven deaths due to pulmonary hemorrhage reported by investigators in the paclitaxel, carboplatin, plus bevacizumab arm as compared to one in the paclitaxel plus carboplatin alone arm. Generally, these serious hemorrhagic events presented as major or massive hemoptysis without a history of minor hemoptysis during bevacizumab therapy.^[Ref]

Renal

Kidney biopsy of six patients with proteinuria showed findings consistent with thrombotic microangiopathy.

In study 5, patients age 65 and older receiving carboplatin, paclitaxel, and bevacizumab had a greater relative risk for proteinuria as compared to younger patients.^[Ref]

Very common (10% or more): Proteinuria (up to 36%)

Uncommon (0.1% to 1%): Nephrotic syndrome^[Ref]

Ocular

Very common (10% or more): Lacrimation increased

Postmarketing reports: Cases of serious ocular adverse reactions have been reported following unapproved intravitreal use of this drug compounded from vials approved for IV administration. These reactions included infectious endophthalmitis, intraocular inflammation such as sterile endophthalmitis, uveitis and vitreitis, retinal detachment, retinal pigment epithelial tear, intraocular pressure increased, intraocular hemorrhage (such as vitreous hemorrhage or retinal hemorrhage and conjunctival hemorrhage). Some of these reactions have resulted in various degrees of visual loss, including permanent blindness.^[Ref]

It has been suggested that reduction in macular edema after treatment may have resulted in anatomic changes at the fovea and may have triggered the visual hallucinations.^[Ref]
