Spots Global Cancer Trial Database for Bevacizumab and ICIs + hSRT in Symptomatic Melanoma Brain Metastases

Study Description

Brief 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).

Detailed Description: Despite significantly improved clinical outcomes for patients with metastatic melanoma, the subset of patients with symptomatic MBM still fare poorly with treatment. The current standard of care for this group of patients is combined immune checkpoint blockade with ipilimumab and nivolumab, with local treatment with neurosurgery or stereotactic radiotherapy added for larger/more symptomatic lesions. Bevacizumab has demonstrated evidence in the treatment of cerebral radiation necrosis and in a case series, promising symptomatic benefit in this group of patients. With strong empirical evidence of the ability to wean patients from steroids, mechanistically, bevacizumab may augment anti-tumour immunity from immune checkpoint blockade. Bevacizumab will be administered 7 days prior to combination immunotherapy with ipilimumab and nivolumab and then given 28 days later to coincide with the second cycle of ipilimumab and nivolumab and thereafter every 3 weeks. The starting dose will be 7.5mg/kg, given intravenously, for a total of four cycles, and is consistent with the existing literature on the treatment of cerebral radiation necrosis. This trial aims to determine the safety of bevacizumab, in combination with ipilimumab, nivolumab and hSRT, defined as no more than 1/6 patients experiencing a bevacizumab-related SAE in the initial phase of the study.
