Abstract:

Purpose::

A multicenter, randomized, open-label, phase II study (HERIZON; NCT02795988) was conducted to evaluate the clinical and immunologic efficacy of HER-Vaxx (IMU-131), a B-cell, peptide-based vaccine targeting HER2 overexpressed in 6% to 30% of gastroesophageal adenocarcinomas (GEA).

Patients and Methods::

Patients (n = 36) with GEA were treated with standard-of-care chemotherapy (n = 17) or HER-Vaxx plus chemotherapy (n = 19), using the recommended phase 2 dose for the vaccine. Overall survival (OS; primary endpoint), safety, progression-free survival (PFS), clinical response (secondary endpoints), and vaccine-induced HER2-specific antibody levels in serum and correlation with tumor response rates (exploratory endpoints) were investigated.

Results::

A 40% OS benefit [HR, 0.60; median OS, 13.9 months; 80% confidence interval (CI), 7.52–14.32] for patients treated with HER-Vaxx plus chemotherapy compared with OS of 8.31 months (80% CI, 6.01–9.59) in patients that received chemotherapy alone. A 20% PFS difference was obtained for the vaccination arm (HR, 0.80; 80% CI, 0.47, 1.38). No additional toxicity due to HER-Vaxx was observed. The vaccine-induced high levels of HER2-specific total IgG and IgG1 antibodies (P < 0.001 vs. controls) that significantly correlated with tumor reduction (IgG, P = 0.001; IgG1, P = 0.016), had a significant capacity in inhibiting phosphorylation of the intracellular HER2-signaling pathways, mediated antibody-dependent cellular cytotoxicity, and decreased immunosuppressive FOXP3+ regulatory T cells.

Conclusions::

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 with 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.

Abstract:

Purpose::

HER2/neu is overexpressed in up to 30% of gastroesophageal adenocarcinomas (GEA) and linked to poor prognosis. Recombinant mAbs to treat HER2/neu-overexpressing cancers are effective with limitations, including resistance and toxicity. Therefore, we developed a therapeutic B-cell epitope vaccine (IMU-131/HER-Vaxx) consisting of three fused B-cell epitopes from the HER2/neu extracellular domain coupled to CRM197 and adjuvanted with Montanide. This phase Ib study aimed to evaluate the optimal/safe dose leading to immunogenicity and clinical responses (https//clinicaltrials.gov/ct2/show/NCT02795988).

Patients and Methods::

A total of 14 patients with HER2/neu-overexpressing GEA were enrolled, and dose escalation (10, 30, 50 μg) was performed in three cohorts (C). Immunogenicity was evaluated by HER2-specific Abs and cellular responses, clinical responses by CT scans according to RECIST version 1.1.

Results::

IMU-131 was safe without vaccine-related significant local/systemic reactions or serious adverse events. A total of 11 of 14 patients were evaluable for changes in tumor size and vaccine-specific immune responses. One patient showed complete, 5 partial responses, and 4 stable diseases as their best response. HER2-specific IgG levels were dose dependent. In contrast to patients in C1 and C2, all patients in C3 mounted substantial HER2-specific Ab levels. In addition, cellular vaccine responses, such as Th1-biased cytokine ratios and reduced regulatory T cell numbers, were generated. Progression-free survival was prolonged in C3, correlating with the vaccine-specific humoral and cellular responses.

Conclusions::

IMU-131 was well tolerated and safe. The induced HER2-specific Abs and cellular responses were dose dependent and correlated with clinical responses. The highest dose (50 μg) was recommended for further evaluation in a phase II trial, with chemotherapy + IMU-131 or chemotherapy alone, which is currently ongoing.

Abstract Background HER2/neu is overexpressed in 15% - 25% of gastric cancers. IMU-131 is a B-cell peptide vaccine composed of 3 epitopes of the extracellular domain of HER2/neu. Antibodies against IMU-131 peptides elicit antitumor activity in vitro and a phase I study demonstrated safety and immunogenicity in Her-2 +/ ++ breast cancer patients. Methods IMU-131 was given to patients with HER2/neu positive gastric cancer in an open-label phase 1b dose escalation trial with 14 Asian and Eastern European sites. Each patient received IMU-131 on Days 0, 14, and 35, with cisplatin and 5-fluorouracil or capecitabine every 21 days. Patients remained on study until disease progression. Ongoing patients received boosters at D98 then every 84 days. Results 14 patients were enrolled with 10 HER2 overexpressing (7 x HER2 +++, 3 x HER2 ++ FISH positive) and 4 HER2 ++ expressing tumors. Mean age was 57 yo (range of 21 - 79) with ECOG scores of 0 or 1 in 7 patients each. There were 9 Asian and 5 Caucasian patients with 5 females and 9 males. Dose levels were 10, 30 and 50 µg with 3, 6, and 5 patients respectively. 11 patients received all 3 doses and 3 patients received only 2 doses due to disease progression. P467 and HER2 antibodies were generated at all dose levels with patients dosed at 50µg responding to the vaccine with equally high antibody levels. There were no DLTs or SAEs related to IMU-131. Of the 14 patients dosed 11 were evaluable for tumor progression at day 56 and later. Of those patients, the best response was 1 CR, 5 PR, 4 SD and 1 PD. Two patients, both dosed at 50µg IMU-131, remain on study after D266, with one patient’s tumor reduced by approximately 80% from 177mm at baseline to 37mm at D266. Conclusions Safety data indicate that IMU-131 is well tolerated with no significant local or systemic reactions. There were no dose-limiting toxicities observed, no significant injection site reactions and no IMU-131 related SAEs. The 50µg dose produced the most consistent P467 and HER-2 specific antibodies compared to 10 and 30µg doses with preliminary response data demonstrating 50µg of IMU-131 is associated with tumor size reduction. The 50µg dose of IMU-131 is being used in the phase 2 study. Clinical trial identification Identifier: NCT02795988. Legal entity responsible for the study Imugene Ltd. Funding Imugene Ltd.

Imugene's oncolytic virotherapy VAXINIA and B cell immunotherapy HER-Vaxx featured at the AACR Annual Meeting 2024

Oncolytic virus CF33-hNIS (VAXINIA) alone or in combination with KEYTRUDA is a safe treatment option for advanced cancer patients.Encouraging VAXINIA efficacy, including a complete response (CR) and two partial responses (PRs), has warranted cohort expansions in biliary tract cancer and other tumour types.Compared to chemotherapy alone, vaccination with HER-Vaxx was associated with a 40% overall survival benefit.HER-Vaxx induced HER2-specific antibody levels correlate with tumour reduction. SYDNEY, Australia, April 09, 2024 (GLOBE NEWSWIRE) -- Imugene Limited (ASX: IMU), a clinical stage immuno-oncology company, is pleased to announce poster presentations featuring its CF33 oncolytic virotherapy VAXINIA and B cell immunotherapy HER-Vaxx at the American Association for Cancer Research (AACR) Annual Meeting 5-10 April 2024, in San Diego, CA. Daneng Li, M.D., a City of Hope associate professor in the Department of Medical Oncology & Therapeutics Research commented, “The results show that our novel oncolytic virus — both alone or in combination with immunotherapy — has the ability to control various cancer types previously resistant to other treatment options, and these early results provide patients with hope of a new treatment option for cancers refractory to standard treatment.” Imugene Managing Director & CEO Leslie Chong said: "Preliminary data from the MAST trial demonstrates encouraging anti-tumour activity with our oncolytic virus CF33-hNIS (VAXINIA). Notably, one patient with cholangiocarcinoma, or biliary tract cancer, achieved an immunological complete response (CR), meaning the disappearance of all signs of their cancer after treatment with VAXINIA, with no known recurrence after one year. These encouraging results warrant further investigation in patients will biliary tract cancer and other cancers. In addition, further analysis of the T cell repertoire reveals that T cell diversity may serve a predictive biomarker, which can be used to prospectively identify appropriate patients for treatment.” Details on the poster presentations are below: Presentation Title: Oncolytic virus CF33-hNIS for the treatment of advanced cancerAbstract Presentation Number: CT182Session Date and Time: Tuesday April 9, 2024, 9:00 AM - 12:30 PM PTSession Title: First-in-Human Phase I Clinical Trials 2Presenter: Daneng Li, MD Highlights include: At the data cut-off of 19 December 2023, there were 31 efficacy-evaluable patients in the MAST study. In the intratumoural (IT) cohorts, 7 of 16 (44%) injected lesions had a reduction in tumour burden and 3 lesions were completely eradicated. Three of the IT treated patients had an objective response: 1 complete response by iRECIST in a patient with cholangiocarcinoma and 2 partial responses by RECIST in patients with melanoma. In the intravenous (IV) cohorts, 9 of 17 (53%) patients achieved stable disease as their best response. Patients who received prior checkpoint blockade therapy derived clinical benefit with and without pembrolizumab. Viral replication, assessed by SPECT, was higher in patients who had a reduction in tumour burden.Patients with a higher level of T cell diversity in peripheral blood (pre-treatment) respond better to VAXINIA therapy, consistent with the known mechanism of action of oncolytic virotherapies and their ability to promote an anti-tumour T cell response.Both IT- and IV-treated patients have promising immunological changes in on-treatment tumour biopsies (including increases in cancer fighting CD8 T cells and PD-L1 expression) indicated that VAXINIA can transform the tumour microenvironment.Several patients have had prior treatment with checkpoint blockade, including a stable disease cholangiocarcinoma patient and two melanoma partial response patients. This suggests that VAXINIA +/- checkpoint inhibitor combination could be used in the checkpoint therapy refractory setting, which is seeing a growing and unmet market in oncology, by altering the tumour microenvironment. Presentation Title: 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 studyPoster Number: CT215Session Date and Time: Tuesday April 9, 2024, 9:00 AM - 12:30 PM PTSession Title: Phase II Clinical Trials 1Presenter: Joshua Tobias Ph.D. Highlights include: HER-Vaxx treatment produced robust anti-HER2-IgG and IgG1 antibody response (p<0.001).HER-Vaxx induced HER2-specific antibodies able to mediate antibody-dependent cell cytotoxicity (ADCC) and inhibit intracellular HER2 phosphorylation and correlated with tumour reduction.The HER-Vaxx induced HER2-specific antibodies demonstrate a similar mechanism of action to HERCEPTINâ validating B cell immunotherapy as an alternative anti-cancer agent to monoclonal antibodies. About the MAST TrialThe multicenter Phase 1 MAST trial commenced by delivering a low dose of VAXINIA to patients with metastatic or advanced solid tumours who have had at least two prior lines of standard of care treatment. The City of Hope-developed oncolytic virus has been shown to shrink colon, lung, breast, ovarian and pancreatic cancer tumours in preclinical laboratory and animal models¹. Overall, the study aims to recruit cancer patients across approximately 10 trial sites in the United States and Australia. The clinical trial is titled “A Phase I, Dose Escalation Safety and Tolerability Study of VAXINIA (CF33- hNIS), Administered Intratumorally or Intravenously as a Monotherapy or in Combination with Pembrolizumab in Adult Patients with Metastatic or Advanced Solid Tumours (MAST).” The trial commenced in May 2022 and is anticipated to run for approximately 24 months while being funded from existing budgets and resources.

Gastric Cancer Overview Stomach cancer is cancer that begins within the stomach or on the stomach wall. It is also known as gastric cancer. Stomach cancer is more common in the elderly. People aged 75 and above account for approximately 50 out of every 100 cases (around 50%). It affects men more than women. The exact gastric cancer causes are not known. Stomach cancer is linked to Helicobacter pylori, a bacteria that lives in the stomach. The most common gastric cancer symptoms are difficulty swallowing (dysphagia), weight loss, persistent indigestion (dyspepsia), feeling full after eating small amounts, feeling or being sick, and fatigue due to low red blood cell count (anaemia). Several tests, such as ultrasound, imaging tests, blood tests, and others, are used for gastric cancer diagnosis. Gastric cancer patients can receive a variety of treatments. Standard gastric cancer treatment consists of seven types: surgery, endoscopic mucosal resection, chemotherapy, radiation therapy, chemoradiation, targeted therapy, and immunotherapy.

Merck’s Keytruda Adds Advanced Endometrial Carcinoma to Winning Roster

Courtesy of Kena Betancur/Getty Images Merck’s Keytruda has become an approved treatment for yet another indication: unresectable or metastatic advanced endometrial carcinoma. Know more about it here. Keytruda is an approved treatment for endometrial carcinoma. (Courtesy of Kena Betancur/Getty Images) Merck ’s Keytruda (pembrolizumab) has become a Food and Drug Administration (FDA) -approved treatment for yet another indication- unresectable or metastatic advanced endometrial carcinoma that is microsatellite instability-high or mismatch repair (MSI-H or dMMR). This announcement adds another win to Merck’s trophy case, as the biologic has already impressed the biopharmaceutical industry with an extensive array of indications, including for three other gynecological cancers. Keytruda is an anti-programmed death receptor therapy that utilizes monoclonal antibodies to block interactions between PD-1 and ligands. This interaction typically results suppresses T lymphocyte activation, allowing the proliferation of tumor cells. Patients must have attempted systemic therapy treatments without success and cannot be candidates for curative surgery or radiation. About the Trial of Keytruda for Endometrial Carcinoma The KEYNOTE-158 Phase II trial ( NCT02628067 ) is a non-randomized, open-label trial that spans 27 study locations and involves various cohorts to evaluate Keytruda intervention of a multitude of advanced solid tumors. The cohort of endometrial carcinoma patients is comprised of 90 patients aged between 35 and 56 and resulted in a 46% treatment response rate. The treatment regimen included an intravenous injection every three weeks for up to two years, so long as the patient did not display signs of disease progression or toxicity. Patients underwent an average of 8.3 months of treatment before reaching either of these points. For 68% of the patients who responded to treatment, the positive physiological response continued for at least 12 months, with a smaller cohort experiencing 24 months of response. The classification of endometrial carcinoma as MSI-H or dMMR accounts for 30% of cases. Previously, combination therapy with lenvatinib was approved, indicated for advanced endometrial carcinoma that is not categorized as MSI-H or dMMR. Over 65,000 women are diagnosed with endometrial carcinoma, and 12,500 fatalities are attributed to the disease annually. Endometrial carcinoma is the most prevalent of uterine cancers. Along with endometrial carcinoma, Keytruda has been approved for treatment of non-small cell lung cancer, unresectable or metastatic melanoma, recurrent head and neck squamous cell carcinoma, Hodgkin lymphoma, B-cell lymphoma, urothelial carcinoma, non-muscle-invasive bladder cancer and microsatellite instability-high or mismatch repair deficient cancer. Additionally, ongoing clinical trials are investigating Keytruda indicated for ovarian cancer, triple-negative breast cancer, metastatic castration-resistant prostate cancer , advanced-stage lung cancer, renal cell carcinoma and solid tumors with certain biomarkers. The biologic will likely continue to impress, as it is involved in over 1,700 clinical trials, evaluating how broad the treatment can reach. Humanized monoclonal antibody treatments such as Keytruda have been heavily represented in the news since the onset of the COVID-19 pandemic, as the immunotherapeutic mechanism works to heighten the body’s immune response. Other than using it to treat endometrial carcinoma, a Phase II collaboration with Imugene was also announced last week that will investigate the safety and efficacy of Keytruda in combination with Imugene’s HER-Vaxx., an immunotherapeutic B-cell activator. The collaboration, nextHERIZON, seeks to gather data on how patients with metastatic HER-2/neu over-expressing of gastroesophageal junction adenocarcinomas respond to the combination therapy. Keytruda has been granted Orphan Drug Designation for research into rare cancers, in exchange for market exclusivity that aids in Merck’s financial successes.
