Tumor size reduction and overall survival improvement in HER2-overexpressing cancer patients vaccinated with HER-Vaxx, a B-cell peptide-based vaccine, plus standard-of-care chemotherapy
(SABCS 2024)
- P1/2 | "We have previously identified three peptides representing B cell epitopes on HER2 extracellular domains, comprising trastuzumab's binding site... In gastric/GEJ cancer patients, HER-Vaxx plus standard chemotherapy improves OS, the vaccine-induced immune responses are significantly associated with tumor size reduction, and a favorable safety profile compared to standard-of-care chemotherapy alone is exhibited. This study suggests a possible inclusion of HER-Vaxx as first line treatment modality in HER2-overexpressing cancers."

Final results of the phase II trial of HER-Vaxx, a B-cell peptide-based vaccine plus standard care of chemotherapy in patients with HER2-overexpressing advanced gastric cancer - (HERIZON)
(ESMO 2024)
- P1/2 | "HER-Vaxx is a B cell peptide-based anti-HER2 vaccine (IMU-131) comprising trastuzumab's binding site... HER-Vaxx plus standard chemotherapy improves the OS benefit and reduces tumor burden, which correlates with vaccine-induced immune response, and exhibits a favorable safety profile compared to standard-of-care chemotherapy alone. HER-Vaxx vaccine is suggested as a first-in-class immunotherapy in combination with standard chemotherapy."

Phase II trial of HER-Vaxx, a B cell peptide-based vaccine, in HER2-overexpressing advanced gastric cancer patients under platinum-based chemotherapy (HERIZON).
(PubMed, Clin Cancer Res)
- P1/2 | "HER-Vaxx plus standard chemotherapy exhibits an excellent safety profile and improves OS. Furthermore, vaccine-induced immune response was significantly associated with reduced tumor size compared to standard-of-care chemotherapy. The presented vaccination approach may substitute for treatment with trastuzumab, upon unavailability or toxicity, based on further evidence of equivalent treatment efficacy."

Frontline vaccination with the B-cell peptide compound HER-Vaxx (IMU-131), combined with standard-of-care chemotherapy induces high levels of HER2-specific antibodies mediating ADCC and intracellular phosphorylation inhibition resulting in overall survival benefit in patients with HER2+ metastatic or advanced gastric/GEJ adenocarcinoma - Final results from Phase II/HERIZON study
(AACR 2024)
- P1/2 | "HER-Vaxx is a B cell peptide-based anti-HER2 vaccine (IMU-131) comprising trastuzumab's binding site...Chemotherapy consisted of oxaliplatin plus capecitabine and was started at day 0, repeated every 21 days for a maximum of 6 cycles... The previously shown safety profile of HER-Vaxx, along with the improved clinical and antibody responses in HER2-overexpressing GC patients shown here, validate the proof of concept for a first-in-class B-cell immunotherapy based on HER2 B-cell peptides. Clinical trials evaluating further treatment with HER-Vaxx in HER2+ GC are ongoing."

Preclinical and Clinical Observations Implying Combination Therapy to Enhance the Efficacy of the Her-2/neu B-Cell Peptide-Based Vaccine HER-Vaxx and to Prevent Immune Evasion.
(PubMed, Int J Mol Sci)
- "Her-2/neu-targeting therapy by passive application with trastuzumab is associated with acquired resistance and subsequent metastasis development, which is attributed to the upregulation of tumoral PD-L1 expression and the downregulation of Her-2/neu...The downregulation of Her-2/neu and the upregulation of PD-L1 were observed in a patient's primary tumor at the disease progression time point but not prior to vaccination (Her-2/neu IHC: 3 to 0, FISH: 4.98 to 1.63; PD-L1 CPS: 0% to 5%). Our results further underline the need for combination therapy by targeting PD-L1 to prevent metastasis formation and immune evasion of Her-2/neu-positive and PD-L1-negative tumor cells."

(ESMO 2023)
- P1b/2 | "Background HER-Vaxx is a B cell peptide-based anti-Her2 vaccine (IMU-131) comprising B cell epitopes located within trastuzumab's binding site...Chemotherapy consisted of oxaliplatin plus capecitabine and was started at day 0, repeated q. 21 days for a maximum of 6 cycles...Moreover, the vaccine-induced IgG antibodies had the capacity to inhibit intracellular phosphorylation of Her2 and exhibited binding to the gastric cancer cell line N87 overexpressing Her2. Conclusions 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."

Prevention of metastasis formation by combination therapy targeting Her2 and PD-L1 in Her2-expressing tumors based on observed efficacious vaccination against Her2-positive tumors
(ESMO 2023)
- P1b/2 | "We have formulated a Her2 vaccine (HER-Vaxx), comprising B-cell peptide from the trastuzumab binding site, inducing anti-tumor immune responses and immunological memory in pre-clinical and clinical investigations...Conclusions These results strongly suggest an immune evasive tumor cell response with an upregulation of PD-L1 expression in both, the clinical and preclinical settings. A combination therapy targeting both Her2 and PD-L1 in Her2-overexpressing tumors might efficiently prevent metastasis formation and immune evasion."
