Rintega (rindopepimut)

The analysis revealed that combination therapies generally demonstrated superior efficacy compared to the single ones, while monotherapies exhibited greater potency than temozolomide (TMZ). In terms of median progression-free survival (PFS), the combinations of Afatinib plus TMZ (SUCRA: 62.28%), rindopepimut (CDX-110) plus TMZ (SUCRA: 62.27%), and depatuxizumab mafodotin (Depatux M) plus TMZ (SUCRA: 54.4%) ranked among the top tier. For median overall survival (OS), the combinations of CDX-110 plus TMZ (SUCRA: 68.8%), Depatux M plus TMZ (SUCRA: 68.3%), and Nimotuzumab plus TMZ (SUCRA: 52.5%) were positioned in the upper echelon. In terms of prolonging both median PFS and median OS in GB, CDX-110 plus TMZ and Depatux M plus TMZ have shown slightly better than comparable therapies. However, further clinical trials are needed to confirm the effectiveness of other drugs in this respect.

For example, the CDX-110 (rindopepimut) NeoAg peptide vaccine derived from the EGFRvIII deletion mutant in combination with temozolomide and radiotherapy has shown efficacy in treating EGFRvIII-harboring glioblastoma multiforme (GBM) patients undergone surgery in multiple Phase I and II clinical trials. The efficacy of NeoAg-targeting peptide vaccines may be further improved by combining with other modalities such as tyrosine kinase or immune checkpoint inhibitor (ICI) therapy, which are currently being tested in animal models and clinical trials. Herein, we review the most current basic and clinical research progress on EGFR-targeted peptide vaccination for the treatment of NSCLC and other solid tumor types.

With respect to cancer vaccines, rindopepimut has been well-studied in glioblastoma (GBM) patients with the EGFRvIII mutation, with early results from phase II trials showing possible efficacy in carefully selected GBM patients...However, it is important to keep in mind that the field is still in its infancy and many clinical trials are still early-phase. Several, clinical trials are currently underway to further explore the role of immunotherapy for CNS malignancies.

Regorafenib, rindopepimut and neoadjuvant programmed death 1 (PD-1) inhibitors are promising agents for rGBM, while regorafenib is effective in both O-methylguanine DNA methyltransferase (MGMT) promoter methylated and unmethylated patients. Temozolomide rechallenge and alkylating agents combined with bevacizumab can be useful for patients with MGMT methylation, and patients with isocitrate dehydrogenase (IDH) mutations or second recurrence can benefit from vocimagene amiretrorepvec (Toca 511). Some phase I trials on targeted therapy and immunotherapy have shown positive results, and results from further studies are expected. In addition to the analysis of existing clinical trial results, forthcoming trials should be well designed, and patients are encouraged to participate in appropriate clinical trials.
