Summary

Single arm phase I/II trial to evaluate the safety and efficacy of the combination of bevacizumab, with ipilimumab plus nivolumab, and hypofractionated stereotactic radiotherapy (hSRT) in patients with symptomatic melanoma brain metastases (MBM).

Conditions

  • Melanoma Brain Metastases

Interventions

DRUG

Bevacizumab

Bevacizumab is a humanised monoclonal antibody with molecular weight 167kD that inhibits all isoforms of the vascular endothelial growth factor (VEGF) and is produced from a Chinese hamster ovary mammalian system. It has high specificity for isoform-A and has a half-life of \~21 days.

DRUG

Ipilimumab

Ipilimumab is an immune checkpoint inhibitor (ICI) that targets anti-tumour immunity. Ipilimumab is a recombinant human immunoglobulin monoclonal antibody that binds CTLA4 and blocks the interaction between CD80/86 and CTLA4.

DRUG

Nivolumab

Nivolumab ia an immune checkpoint inhibitor (ICI) that targets anti-tumour immunity. Nivolumab is a fully human monoclonal IgG4 antibody targeting PD-1 which demonstrates activity across a range of tumours.

RADIATION

Hypofractionated stereotactic radiotherapy

Hypofractionated stereotactic radiotherapy (hSRT) will be delivered to previously untreated brain metastases in eligible participants. hSRT will be delivered to all symptomatic brain metastases, all brain metastases \>1 cm and all brain metastases located in eloquent areas of the brain. hSRT will be commenced after the first cycle of nivolumab plus ipilimumab and completed before the second cycle of nivolumab plus ipilimumab. hSRT should be commenced within 1 week from the planning MRI.
