Case series with targeted therapy based on NGS screening.

Series Approach Therapy decision criteria Outcome parameters Results/Signs of activity Comment
Lazaridis et al. [126]

Retrospective, mostly 2nd relapse

n = 41 gliomas screened, 36/41 with actionable target, 18/36 with targeted therapy

NGS panel, IHC panel, Seq (TERT), FISH (CCDKN2A/B)

Known BBB penetration

Molecular tumor board decision

PFS/OS of 16 rGBM with vs. 16 without targeted therapy

mPFS 3.8 vs. 2.0 months

PFS6 25 vs. 20%

mOS 13 vs. 4 months (P < 0.05)

High PFS > 7 months and PFS2‐PFS1 > 5 months in Dabrafenib/trametinib (n = 2)

Cabozantinib (n = 2)

Reproduced the known activity of BRAF inhibitors

Median 1 prior treatment

Precision therapy aspect of Cabozantinib difficult to analyze due to the multikinase activity including VEGFR inhibition

Renovanz et al. [122]

Prospective

n = 262 GBM screened, 41 treated based on NGS results, 36 evaluable for response

NGS panel, RNA seq, IHC panel

Some signs of activity with FGFR‐fusion or mTOR‐directed therapy

> 2 lines of prior treatment

Large cohort, also reporting on other CNS tumor entities

Blumenthal et al. [124]

Retrospective

n = 43 (GBM, AA), 41/43 with actionable targets, 13/43 treated

NGS panel

Treatment decision by physician's choice

Response, duration of treatment, mOS

no response with EGFR, MEK, CDK4/6, or mTOR‐directed therapy

mOS 4.6 months, longest OS 10 months (EGFR‐directed afatinib)

No clear signs of activity, even with combination treatment

Median 1 prior treatment

Small and heterogenous cohort

Feasibility of approach shown

Sign of activity in a single GBM patient

Padovan et al. [123]
