Title:

1536P - HERIZON: A phase II study of HER-Vaxx (IMU-131), a HER2-targeting peptide vaccine plus standard of care chemotherapy in patients with HER2+ advanced stomach cancer - Dose-dependent anti-cancer antibodies correlating with improved clinical outcome

Published date:
10/16/2023
Excerpt:
Pients were randomized to chemotherapy alone (n=17) or HER-Vaxx (50μg dose, n=19; 100μg, n=7) plus chemotherapy….Vaccination with HER-Vaxx in patients with Her2-overexpressing GC at doses of 50μg and 100μg led to an anti-tumour effect that correlated with anti-Her2 IgG antibody levels.

Title:

HERIZON: A phase 2 study of HER-Vaxx (IMU-131), a HER2-targeting peptide vaccine, plus standard of care chemotherapy in patients with HER2-overexpressing metastatic or advanced gastric/GEJ adenocarcinoma— Overall survival analysis.

Published date:
01/17/2023
Excerpt:
Analysis showed a 42% survival benefit for patients treated with HER-Vaxx plus chemotherapy compared to chemotherapy alone. This translated into an OS HR of 0.580 (80% 2-sided CI: 0.362, 0.927) with a statistically significant p-value of 0.066. The median OS for patients receiving HER-Vaxx plus chemotherapy was 13.9 (7.5, 14.3) months, compared to 8.3 (6.0, 9.6) months in patients treated with chemotherapy alone....These data demonstrate that in patients with HER2 over-expressing gastric/GEJ cancer active HER2 immunization with HER-Vaxx is safe and provides relevant clinical benefit over standard of care chemotherapy.

Title:

74MO - HERIZON overall survival results: A study of IMU-131, a HER2 targeting peptide vaccine, plus standard of care chemotherapy in patients with HER2 overexpressing metastatic or advanced gastric/GEJ cancer

Published date:

Excerpt:
Analysis showed a 42% survival benefit for patients treated with IMU-131 plus chemotherapy compared to chemotherapy alone….The median OS for patients receiving IMU-131 plus chemotherapy was 13.9 months, compared to 8.3 months in patients treated with chemotherapy alone....These results demonstrate that active immunization with the B-lymphocyte stimulating HER2 vaccine, IMU-131 (HER-Vaxx), may provide treatment benefits consistent with traditional monoclonal antibodies with a corresponding adaptive immune response without added toxicity.
