Summary of available clinical trials on nanomaterials-based tumor immunotherapy

NanomaterialsCargo moleculesIndicationsClinical stageKey findingsReferences
Cyclodextrin polymer-based nanoparticleSmall interfering RNA targeting the M2 subunit of ribonucleotide reductaseMelanoma, gastrointestinal cancer, prostate cancerPhase Ia/IbCALAA-01 pharmacokinetics revealed that peak concentration and exposure correlate with body weight across species.[241]
Poly-L-lysine, double-stranded RNA complex with polyinosinic-polycytidylic acidNY-ESO-1 antigen proteinAdvanced or recurrent esophageal cancerPhase ICombination of CHP-NY-ESO-1 with poly-ICLC induced superior antigen-specific T-cell responses compared to monotherapy.[242]
Poly-L-lysine, double-stranded RNA complex with polyinosinic-polycytidylic acidNY-ESO-1 antigen protein + monomideHigh-risk resected melanomaPhase I/IIThe CHP-NY-ESO-1 combination was well tolerated and effectively induced integrated CD4+ and CD8+ T-cell responses.[243]
Poly-L-lysine pullulan (CHP) nanoparticleNY-ESO-1 antigen proteinEsophageal cancerPhase I (NCT01003868)Tumor immunogenicity of the CHP-NY-ESO-1 vaccine was confirmed, showing promising therapeutic potential.[244]
Nanoparticle albuminHER2 protein 1–146HER2-expressing solid cancerPhase IHER2-specific CD8+ T-cell responses were successfully detected in patients.[245]
Nanoparticle albumin-bound (nab)-paclitaxel + atezolizumab (anti-PD-L1 antibody)-Unresectable locally advanced or metastatic triple-negative breast cancerPhase III (NCT02425891)Median progression-free survival was 7.5 months in PD-L1 positive patients treated with the nanoparticle-bound atezolizumab combination.[246]
Poly (beta-amino ester) based nanomaterialPlasmids encoding 19.4-1 BBZ CAR and a piggybac transposaseTo be determinedPhase I (projected 2020–2021)Efficient introduction of DNA plasmids leading to sustained disease remission with long-term therapeutic benefits.[247]
IL-15 super-agonist complexIL-15 super-agonist complex nanogelSolid cancer and lymphomasPhase IThe IL-15 super-agonist nanogel enabled high local cytokine concentrations while maintaining minimal systemic toxicity.[248]
