A retrospective study of bevacizumab only in adults with recurrent temozolomide (TMZ)-refractory anaplastic astrocytoma (AA) with a primary objective of determining progression free survival (PFS). There is no standard therapy for alkylator-resistant AA and hence a need exists for new therapies. Twenty-five patients (15 men; 10 women) ages 26-63 (median 50), with radiographically recurrent AA were treated. All patients had previously been treated with surgery, involved-field radiotherapy, and alkylator-based chemotherapy. Fourteen patients underwent repeat surgery. Patients were treated at second recurrence with bevacizumab (10 mg/kg), once every 2 weeks (defined as a single cycle). Neurological evaluation was performed every 2 weeks and neuroradiographic assessment following the initial two cycles of bevacizumab and subsequently after every four cycles of bevacizumab. All patients were evaluable for toxicity and response. A total of 360 cycles of bevacizumab (median 14 cycles; range 2-40) was administered. Bevacizumab-related toxicity included fatigue (14 patients; 2 grade 3), leukopenia (7; 1 grade 3), deep vein thrombosis (5; 2 grade 3), hypertension (5; 1 grade 3), anemia (4; 0 grade 3) and wound dehiscence (1; 1 grade 3). Sixteen patients (64%) demonstrated a partial radiographic response, 2 (8.0%) stable disease and 7 (28%) progressive disease following two cycles of bevacizumab. Time to tumor progression ranged from 1 to 20 months (median: 7). Survival ranged from 2 to 23 months (median: 9.0). 6-month and 12-month PFS were 60 and 20%, respectively. Bevacizumab demonstrated efficacy and acceptable toxicity in this cohort of adults with recurrent alkylator refractory AA.

A retrospective evaluation of single agent bevacizumab in adults with recurrent glioblastoma (GBM) with an objective of determining progression free survival (PFS). There is no standard therapy for recurrent GBM after failure of alkylator-based chemotherapy. A total of 50 adults, ages 36-70 years (median 64), with recurrent GBM were treated. All patients had previously been treated with surgery, concurrent radiotherapy and temozolomide, post-radiotherapy temozolomide and in 34 patients, one salvage regimen (PCV: 21, cyclophosphamide: 13). A total of 13 patients underwent repeat surgery. Patients were treated at first or second recurrence with bevacizumab, once every 2 weeks, defined as a single cycle. Neurological evaluation was performed every 2 weeks and neuroradiographic assessment following the initial 2 cycles of bevacizumab and subsequently after every 4 cycles of bevacizumab. A total of 468 cycles of bevacizumab (median 2 cycles; range 1-30) was administered. Bevacizumab-related toxicity included fatigue (16 patients; 4 grade 3), leukopenia (9; 1 grade 3), anemia (5; 0 grade 3), hypertension (7; 1 grade 3), deep vein thrombosis (4; 1 grade 3) and wound dehiscence (2; 1 grade 3). 21 patients (42%) demonstrated a partial radiographic response and 29 (58%) progressive disease following 1-2 cycles of bevacizumab. Time to tumor progression ranged from 0.5 to 15 months (median: 1.0 months). Survival ranged from 2 to 17 months (median: 8.5 months). 6-month and 12-month PFS were 42% and 22% respectively. Single agent bevacizumab demonstrated efficacy and acceptable toxicity in this cohort of adults with recurrent alkylator-refractory GBM.

Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, has shown promise in treating recurrent adult high-grade glioma (HGG). However, there is very little data on recurrent or progressive pediatric HGG treated with bevacizumab. We report the results of a single institution experience using bevacizumab and irinotecan in children who relapsed or progressed following standard therapy. Twelve pediatric patients with recurrent or progressive HGG received bevacizumab at 10 mg/kg every 2 weeks with irinotecan at 125 mg/m(2). Magnetic resonance imaging (MRI) was performed prior to therapy and every 8 weeks subsequently. Ten patients had supratentorial HGG; 2 had DIPG. Radiological responses were defined according to MacDonald's criteria. Progression-free survival (PFS), overall survival (OS), and toxicities were analyzed. Ten (83.3%) patients tolerated bevacizumab without serious toxicity. Therapy was discontinued in 1 patient because of anaphylaxis. Another patient developed grade III delayed wound healing and deep vein thrombosis. Two patients (16.7%) experienced a partial response after the first MRI. No complete radiographic responses were seen. Stable disease was noted in 4 (33.3%) patients. The median PFS and OS were 2.25 and 6.25 months, respectively. A diffuse invasive recurrence pattern was noted in 5 (45.5%) patients. Treatment tolerance, toxicity, and recurrence profiles were comparable to adult HGG patients treated with bevacizumab. However, the radiological response rate, response duration, and survival appeared inferior in pediatric patients. Genetic differences in pediatric gliomas might account for this difference.

Internal jugular vein thrombosis is much less common than deep venous thrombosis of lower limbs and is generally caused by an indwelling venous catheter or otological infection. Several cases of internal jugular vein thrombosis associated with malignancy have been also reported. Bevacizumab, a monoclonal neutralizing antibody against vascular endothelial growth factor, has shown benefits in the treatment of many types of malignancy and its use is increasing. Serious adverse effects, however, are associated with the use of bevacizumab, including venous thromboembolism. In this article, we present a rare case of non-small cell lung cancer complicated by pulmonary embolism due to internal jugular vein thrombosis associated with bevacizumab.

Bevacizumab is frequently used to treat patients with recurrent high-grade glioma (HGG), but responses are generally not durable. Panobinostat is a histone deacetylase inhibitor with anti-neoplastic and anti-angiogenic effects and may work synergistically with VEGF inhibitors. We performed a phase I study to evaluate the safety and tolerability of the combination of orally administered panobinostat with bevacizumab in patients with recurrent HGG. Patients with recurrent HGG were treated on a 3 + 3 trial design. Patients received bevacizumab 10 mg/kg every other week in combination with oral panobinostat. The starting dose of panobinostat was 20 mg three times per week, weekly (cohort 1). Due to concerns for thrombocytopenia with the weekly dosing regimen, the protocol was amended to examine an every other week regimen. Cohort 2 received panobinostat 20 mg three times per week, every other week, and cohort 3 received 30 mg three times per week, every other week. Dose-limiting toxicity during the first 30 days was used to determine the maximum-tolerated dose. Twelve patients (median age 50, median KPS 90) with recurrent HGG were enrolled. One dose-limiting toxicity (DLT) (Grade 3 thrombocytopenia) was observed in cohort 1. No DLTs were observed in cohorts 2 and 3. The following grade 3 toxicities were seen in one patient each: thrombocytopenia, hypophosphatemia, esophageal hemorrhage, and deep venous thrombosis. There were no grade 4 or 5 toxicities. There were three patients with partial responses and seven with stable disease. The recommended doses for further study are oral panobinostat 30 mg three times per week, every other week, in combination with bevacizumab 10 mg/kg every other week. A phase II clinical trial in recurrent HGG is underway.

Intravitreal bevacizumab (Avastin) has been used off label for various conditions, including proliferative sickle cell retinopathy (PSR). Some authors have reported a more rapid resolution of the vitreous haemorrhage in Goldberg stage 4 PSR. Following injection of 1.25 mg of bevacizumab in each eye in a case of PSR (right eye with stage 3 sea fan neovascularisation and left eye with organising vitreous haemorrhage), we recently found a surprising association with significant secondary hyphaema on the fifth day post injection in the eye with vitreous haemorrhage. After 4 weeks, there was a dramatic fibrotic resolution of the stage 3 sea fan in the other eye. Systemic bevacizumab as used in the management of colorectal cancer has been associated with bleeding diathesis in some cases, as well as with deep venous thrombosis. The rheological profile of bevacizumab is not clear-cut at the moment and the drug should therefore be used with caution in cases of stage 4 PSR.
