  • Platelets ≥ 100,000/μL
  • Hemoglobin ≥ 90 g/L (9g/dL)
  • Total Bilirubin ≤ 3 x ULN
  • AST(SGOT)/ALT(SGPT)/Alkaline Phosphatase ≤ 3 x ULN Or ≤5x ULN if due to liver involvement by tumor

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

Treatments listed in the registry

  • Memantine Hydrochloride (Drug): Memantine (5mg) is an N-methyl-D-aspartate (NMDA) receptor antagonist given in 21-day cycles over six months in combination with Bevacizumab and Atezolizumab. Each week memantine will be escalated by 5mg as tolerated
  • Bevacizumab (Drug): Bevacizumab (15mg/kg) is a vascular endothelial growth factor inhibitor given in 21-day cycles over six months in combination with Memantine and Atezolizumab.
  • Atezolizumab (Drug): Atezolizumab (1200mg) is a programmed death-ligand 1 (PD-L1) blocking antibody given in 21-day cycles over six months in combination with Memantine and Bevacizumab
