“Dual Checkpoint Blockade Falls Short in Newly Diagnosed uMGMT GBM
Objective
Evaluate if ipilimumab + nivolumab (w/o temozolomide) + RT survival vs. standard RT + temozolomide in uMGMT glioblastoma
Methods
- Phase II/III RCT, 159 pts, KPS ≥ 70, gross/subtotal resection.
- RT 60 Gy/30fx (IMRT) ± TTFields.
- Experimental arm: ipi 1 mg/kg q4wk × 4 + nivo 3 mg/kg q2wk until progression; no TMZ.
Results
- No PFS benefit: 7.7 mo (ipi+nivo) vs. 8.5 mo (TMZ) (HR 1.47)
- OS immature (~13 mo both arms)
- Similar grade 3–4 AE rates; 2 immune-related deaths
Takeaway:
- TMZ remains standard for uMGMT GBM—dual ICI not superior.”
