π§ͺ AMPLIFY-NEOVAC Trial
The AMPLIFY-NEOVAC Trial is a Phase I multicenter clinical trial investigating the combination of an IDH1 R132H-targeted peptide vaccine with an antiβPD-L1 immune checkpoint inhibitor in patients with newly diagnosed IDH1-mutant astrocytomas.
π― Objective
To evaluate the safety, tolerability, and immunogenicity of a combination immunotherapy:
- IDH1 R132H peptide vaccine (used in the NOA-16 trial)
- Atezolizumab (a PD-L1 immune checkpoint inhibitor)
π₯ Patient Population
- Adults with newly diagnosed WHO grade III or IV IDH1 R132H-mutant astrocytomas
- Must have completed standard-of-care therapy (surgery and radiotherapy)
- Patients with or without prior temozolomide exposure may be included
π Rationale
- NOA-16 showed the IDH1 R132H vaccine is safe and immunogenic
- Adding a PD-L1 inhibitor may enhance T cell infiltration and sustain immune responses by preventing T cell exhaustion
- The goal is to amplify anti-tumor immunity and improve long-term outcomes
π¬ Study Design
- Open-label, Phase I
- Two arms:
- IDH1 vaccine alone
- IDH1 vaccine + atezolizumab
- Evaluates:
- Adverse events
- Vaccine-specific T cell responses
- Tumor progression-free survival (PFS)
π Key Points
- Atezolizumab is already approved for several cancers (lung, bladder) and blocks PD-L1 β PD-1 signaling
- The vaccine uses the same 20-mer peptide from NOA-16, targeting the IDH1 R132H mutation
- The trial will help determine if combining checkpoint blockade with vaccination improves response durability
π§ Challenges
- Immune-related adverse events due to checkpoint inhibition
- Blood-brain barrier may limit immune cell access
- Small patient population (IDH1-mutant astrocytomas are rare)
π Connection to NOA-16
- NOA-16 demonstrated feasibility and immune activation using the IDH1 vaccine alone
- AMPLIFY-NEOVAC builds on this by aiming to strengthen and prolong the anti-tumor immune response
π Summary
The AMPLIFY-NEOVAC Trial is an important next step in personalized glioma immunotherapy, exploring whether checkpoint blockade can synergize with neoantigen vaccination to generate deeper, longer-lasting anti-tumor responses in patients with IDH1 R132H-mutant gliomas.
