Personalized Vaccines Show Promise for Hard-to-Treat Cancers
(Cancer Health)
- "Mark Yarchoan, MD...presented findings from a Phase I/II trial of a personalized vaccine for hepatocellular carcinoma (HCC), the most common type of primary liver cancer. Often caused by viral hepatitis, fatty liver disease or heavy alcohol use, HCC is typically diagnosed late, and it is one of the leading causes of cancer-related death worldwide."

Personalized Neoantigen DNA Vaccine (GNOS-PV02) and Pembrolizumab Develop Antitumor Poly-Functional Neoantigen-Specific CD4+ and CD8+ Effector T Cells in Advanced Hepatocellular Carcinoma Therapy
(ASGCT 2024)
- "Our data shows that the personalized DNA-based vaccine in combination with pembrolizumab generates a significant poly-functional neoantigen-specific antitumor CD8+ and CD4+ T cell responses, including T cell clonal expansion and infiltration to the tumor. These features could explain the mechanism of action behind the clinical activity observed in advanced HCC patients."

- "'Essentially GNOS-PV02 aims to (educate) the immune system to recognize antigens that are present in the cancer so that the immune system can better recognize and attack cancer cells,' explained lead study author Mark Yarchoan, MD...'Despite recent advances in the treatment of HCC, only a minority of patients respond to contemporary systemic treatments and the prognosis for patients with advanced disease is inferior to most other tumor types,' Yarchoan said."

Detection of circulating tumor DNA predicts survival in advanced HCC patients treated with personalized therapeutic DNA cancer vaccine in combination with immune checkpoint blockade
(AACR 2024)
- P1/2 | "NeXT Personal®, an ultra-sensitive tumor-informed ctDNA assay was used to longitudinally track ctDNA in advanced hepatocellular carcinoma (HCC) patients treated with GNOS-PV02 (a personalized therapeutic DNA cancer vaccine) in combination with pembrolizumab.Advanced unresectable or metastatic HCC patients that progressed on, or were intolerant to, first-line TKI therapy were enrolled into the Phase 1b/2a GT-30 study [NCT04251117]. ctDNA clearance was observed in all 3 CR patients with a lead time of 483, 126 and 105 days compared with MRI.This ultra-sensitive ctDNA assay shows significant association between ctDNA change and clinical response and survival, and can be used to accurately predict clinical outcome. The convenience of non-invasive liquid biopsy and rapid availability of data could enable the use of ctDNA to allow real-time monitoring of personalized cancer immunotherapy."

Tracking MRD and neoantigen targets using a tumor-informed liquid biopsy platform in HCC patients treated with personalized cancer vaccine and pembrolizumab.
(ASCO 2023)
- P1/2 | "We used an ultra-sensitive, tumor-informed ctDNA platform to longitudinally track tumor neoantigen targets and monitor molecular residual disease (MRD) in advanced HCC patients (pts) being treated with a DNA personalized therapeutic cancer vaccine (GNOS-PV02). Highly sensitive tracking of MRD and neo-antigenic variants over the course of therapy was achieved using a single assay. We show that ctDNA can sensitively monitor disease status non-invasively, potentially leading to accurate clinical outcome prediction. Additionally, the ease of sample handling, analysis, and rapid availability of data could enable the use of ctDNA monitoring to allow real-time dynamic personalized cancer immunotherapy."

Effect of personalized immunization with GNOS-PV02 of patients with hepatocellular carcinoma on TCR clonal expansion, tumor infiltration, and vaccine-specific reactivity.
(ASCO 2023)
- P1/2 | " Paired blood and tumor biopsy samples from patient #8 enrolled in the GT-30 study were collected before and after treatment with GNOS-PV02 (1mg) + plasmid-encoded IL-12 (0.3mg) + Pembrolizumab (200mg). PTCV treatment resulted in neoantigen-specific T cell responses, clonal expansion in the periphery and primary lesion, and tumor infiltration of T cells with an activated phenotype. TCR-engineered high-frequency T cells found in the tumor are reactive to PTCV-encoded neoantigens post-treatment. These results may account for the observed objective decrease in the primary tumor size."

HCC is resistant to immune checkpoint therapies in the majority of patients due to the largely immune excluded tumor microenvironment. Therapies that can bring CD8+ T cells into the tumor microenvironment, such as effective therapeutic cancer vaccines targeting cancer neoantigens, can reprogram the tumor microenvironment for checkpoint inhibitor therapy,' stated Mark Yarchoan..."

Profound shrinkage and control of the liver lesion resulted, now continuing for over a year. A metastatic adrenal lesion newly developed four months post initial treatment, the neoantigen content of which was similar but not identical to the liver primary lesion: while 16 of the original liver neoantigens remain, all four of the vaccine epitopes with strongest T cell responses were absent in the adrenal lesion....Abstract #692 summarizes the use of circulating tumor DNA (ctDNA) analysis in the GT-30 trial, to monitor tumor burden (progression or reduction). It was concluded that ctDNA may be a useful tool for monitoring disease in a patient specific manner."
