Request a sample and discover the recent advances in oncolytic virus drugs @ Key Factors Driving the Oncolytic Virus Therapy Market Growing Cancer Incidence: The global rise in cancer prevalence, especially in hard-to-treat solid tumors, has intensified demand for novel, effective treatment modalities. Conventional therapies such as chemotherapy and radiation often have significant side effects and limited long-term efficacy, motivating the adoption of immunotherapeutic alternatives like oncolytic virus therapies. Increasing Understanding of Cancer Biology: Growing knowledge of cancer biology has enabled the development of oncolytic virus therapies that selectively target and destroy cancer cells while sparing healthy cells. Advancements in Viral Engineering: These advances are enabling more precise, targeted oncolytic virus therapies, significantly expanding the global oncolytic virus therapy market. Rising Adoption of Personalized Medicine: Oncolytic virus therapies align closely with personalized treatment approaches by enabling tailored viral constructs and immunomodulatory payloads based on tumor genomics. What is Oncolytic Virus Therapy? Oncolytic virus therapy is an innovative form of cancer treatment that uses genetically engineered or naturally occurring viruses to selectively infect and destroy cancer cells. These viruses replicate inside tumor cells, causing them to burst while leaving healthy cells largely unharmed. As the cancer cells break apart, they release tumor antigens that help activate the body's immune system, enhancing its ability to recognize and attack remaining cancer cells. This dual action, direct tumor destruction and immune stimulation, makes oncolytic virus therapy a promising approach in modern oncology, often used alongside other treatments such as immunotherapy or chemotherapy. Applications of Oncolytic Virus Therapy Oncolytic virus (OV) cancer therapies can be used for both diagnosis and treatment of cancer. OVs can function as cancer vaccines by boosting tumor-specific T-cell responses. Oncolytic viruses can be engineered with immunostimulatory molecules to enhance immune activation. OVs show strong synergy when combined with other immunotherapies, such as checkpoint inhibitors. Oncolytic Viruses in Combination with Chemotherapy Chemotherapy works systemically, unlike surgical resection or radiotherapy. It remains essential for treating patients with disseminated (widespread) cancer. Because chemotherapy is systemic, it is often combined with oncolytic viruses (OVs), which typically require localized delivery to achieve a strong antitumor effect. Systemically administered OVs have shown limited therapeutic benefit in several clinical trials. Delivering OVs effectively to metastatic sites remains a major challenge. Therefore, using chemotherapy as a systemic adjuvant to localized OV therapy is of significant clinical interest and is currently being actively investigated. Oncolytic Virus Market Analysis: Drug Profile IMLYGIC: Amgen IMLYGIC (talimogene laherparepvec), developed by Amgen, is a first-of-its-kind oncolytic viral therapy for melanoma that cannot be surgically removed. It combines direct tumors destruction with immune system stimulation. The therapy is based on a genetically engineered herpesvirus engineered to preferentially infect and destroy cancer cells, releasing GM-CSF to trigger a broader anti-tumor immune response. In the Phase III OPTiM trial, IMLYGIC produced durable responses in about 16% of patients, compared with 2% with GM-CSF alone, and overall responses in roughly 26%. Patients at earlier disease stages achieved better outcomes, with some achieving long-term control. The treatment is usually well tolerated, with most adverse effects being mild and resembling flu symptoms. Although its independent effect on survival and deep organ metastases is modest, its value is most evident when combined with checkpoint inhibitors. Early data show response rates approaching 56%, and ongoing studies aim to further define these synergistic benefits. As the first FDA-approved oncolytic virus in the West, IMLYGIC has validated the broader concept of viral immunotherapy and is now being explored as a component of combination immuno-oncology approaches. Oncorine: Shanghai Sunway Biotech Oncorine, also known as H101, is a genetically engineered adenovirus with an E1B gene deletion developed by Shanghai Sunway Biotech in China. It is administered alongside chemotherapy to treat nasopharyngeal carcinoma and head and neck cancers. Its approval and effective clinical use have significantly advanced oncolytic virus–based cancer immunotherapy. Marketed as Recombinant Human Adenovirus Type 5 Injection, Oncorine became the first oncolytic virus approved for cancer treatment by the Chinese State Food and Drug Administration (CFDA) in November 2005. Since its introduction, it has demonstrated a favorable safety profile and notable antitumor activity across various cancers and malignant pleural effusions. Exploratory clinical studies have also evaluated Oncorine for treating liver cancers, pancreatic cancer, cervical cancer, malignant melanoma, and metastatic liver tumors.

This collaboration includes preclinical in vitro and in vivo studies, followed by a Phase I investigator-initiated trial to be conducted exclusively in China at premier CAR-T clinical centers. The approach utilizes Imugene's CF33-CD19 virus to induce CD19 expression on tumor cells, rendering them susceptible to targeting by CD19 CAR-T therapies, a transformative "mark and kill" strategy. In July 2025, Calidi Biotherapeutics, Inc., a clinical-stage biotechnology company pioneering the development of targeted therapies with the potential to deliver genetic medicines to distal sites of disease, announced that it received Fast Track designation from the U.S. Food and Drug Administration (FDA) for CLD-201 (SuperNova), the company's allogeneic adipose stem-cell loaded oncolytic virus for the treatment of soft tissue sarcoma. In June 2025, Oncolytics Biotech presented a poster demonstrating the role of pelareorep in activating anti-tumor immunity in PDAC. In May 2025, Candel Therapeutics, Inc. announced that the U.S. Food and Drug Administration (FDA) had granted Regenerative Medicine Advanced Therapy (RMAT) designation to CAN-2409 (aglatimagene besadenovec), the Company's biological immunotherapy lead candidate, for the treatment of newly diagnosed localized prostate cancer in patients with intermediate-to-high-risk disease. CAN-2409 was also previously granted FDA Fast Track designation for the same indication. In May 2025, Elicera Therapeutics AB announced that it had entered into a Material Transfer Agreement (MTA) with University Hospital Tübingen in Germany. Under the agreement, the company's oncolytic virus candidates ELC-100 and ELC-201 will be included in tests aimed at developing a new type of companion diagnostic to predict the potential success of a novel neuroendocrine neoplasm (NEN) therapy, immuno-virotherapy. In April 2025, Hangzhou ConVerd Co., Ltd. announced that the first Phase IIa clinical study of hV01, ConVerd's first oncolytic vaccinia virus product, had successfully completed first patient dosing, with the subject in good condition. This phase IIa clinical study investigates the administration of a single dose of recombinant human IL-21 oncolytic poxvirus injection (hV01) per cycle for the treatment of patients diagnosed with advanced sarcoma and cervical cancer. It is important to note that the indication is for advanced sarcoma and recurrent or metastatic cervical cancer for which there is no standard of care available at this stage of the treatment process, or where standard of care has failed.

New data show 100% (6/6) objective response rate (ORR) with EO2463 in previously untreated patients with follicular lymphoma needing treatment in combination with rituximab (SIDNEY Cohort 3)Of the 6 patients, 5 had a complete response (CR), 1 partial response (PR)Patients with follicular lymphoma in watch-and-wait setting (SIDNEY Cohort 2) showed a 52.6% ORR with EO2463 monotherapy Paris, France – 9 DECEMBER 2025 (08:30 CET)Enterome, a clinical-stage company pioneering OncoMimics™, a new class of off-the-shelf, multi-targeted in vivo immune therapies that induce a fast and potent expansion of memory T-cells to fight cancer, today presents highly encouraging updated interim data from two cohorts of patients with low tumor-burden follicular lymphoma in the ongoing SIDNEY Phase 2 trial of its lead OncoMimics™ immunotherapy EO2463. The data were presented at the 67th meeting of the American Society for Hematology (ASH) in Orlando, Florida. In Cohort 3, 100% (6/6) ORR was achieved with EO2463 plus rituximab as first-line treatment for previously untreated patients with low tumor-burden follicular lymphoma in need of treatment. In this feasibility assessment among the 6 patients, 5 had a complete response, and one a partial response. The median time to OR was 17 weeks, and to CR 18 weeks. These results marked an improvement over preliminary data submitted in the abstract for ASH. “These new results are encouraging, despite the limited number of patients. The potent and rapid expansion of specific CD8 T-cells induced by EO2463 supports our understanding that OncoMimics™ trigger memory T-cells to generate sustained immune responses. The data suggest that the combination therapy given as a first-line treatment in patients with low-tumor burden follicular lymphoma should be evaluated in further studies,” said Dr Stephen Smith, principal study investigator at the Fred Hutchinson Cancer Center, University of Washington, Seattle, WA, USA, who presented the data. Data from Cohort 2 continue to show that EO2463 monotherapy produces excellent response rates when offered to patients with newly diagnosed follicular lymphoma or marginal zone lymphoma as an alternative to the standard watch-and-wait regime. Previously undisclosed data from 19 evaluable patients with follicular lymphoma showed a 52.6% ORR as of October. The ORR in the total group of 21 patients with follicular lymphoma or marginal zone lymphoma was 47.6% (14.3% CR and 33.3% PR). Current standard of practice is that, while patients often have visibly swollen lymph nodes, no treatment other than watchful waiting is suggested, as long as they do not show troublesome symptoms. Nevertheless, these patients often are understandably anxious about their disease, which progresses in the majority of cases, and then leads to a decreased quality of life. “These new data with EO2463 contribute more compelling evidence and further strengthen our belief in the potential of our OncoMimics™ multi-targeted in vivo immune therapies for blood cancers. I’m looking forward to initiating Phase 3 testing of EO2463 in patients in the watch-and-wait setting in 2026,” said Pierre Belichard, CEO of Enterome. Follicular Lymphoma, one of several types of indolent Non-Hodgkin Lymphoma, is a difficult to treat chronic condition with relapses, characterized by slow progression and few symptoms, and reduced life expectancy. It is usually diagnosed by the appearance of swollen lymph nodes, and the early stages of the disease can be characterized by a lack of troublesome symptoms such as night sweats, fever or weight loss. There is a widespread consensus among leading investigators on the need for a well-tolerated and effective monotherapy to stop or slow progression for patients in the watch-and-wait setting. EO2463 is an innovative, off-the-shelf OncoMimics™ active immunotherapy that combines four synthetic peptides. These non-self, microbial-derived peptides correspond to CD8 HLA-A2 epitopes that exhibit molecular mimicry with the B lymphocyte-specific lineage markers CD20, CD22, CD37, and CD268 (BAFF receptor). It also includes the helper peptide (CD4+ epitope) universal cancer peptide 2 (UCP2). The unique ability of EO2463 to selectively target multiple B cell markers enables the destruction of malignant B lymphocytes. By ensuring broad target coverage across malignant B cells, this novel approach aims to simultaneously improve safety and maximize efficacy, reducing the tumor cells’ capacity to develop immune-resistance mechanisms such as antigen escape. OncoMimics™ consist of bacteria-derived peptide antigens that closely mimic tumor-associated antigens (TAAs) of solid tumors, or cell linage markers as for B cell lymphomas. These antigens induce a fast and potent in vivo expansion of cytotoxic memory CD8+ T cells that were primed by gut bacteria, and are cross-reactive with TAAs/B cell markers. Because the peptides are “non-self”, OncoMimics™ avoid the self-tolerance that limits many cancer immunotherapies to enable rapid, potent, and durable responses to tumors. The synthetically produced peptides are designed in silico, mining Enterome’s proprietary database of 23 million commensal bacteria genes. Each product combines multiple high-affinity peptides to broaden target coverage and mitigate tumor heterogeneity. OncoMimics™ are easy to manufacture, store, distribute and administer as an “off-the-shelf” subcutaneous injection. OncoMimics™ have achieved rapid and potent responses in clinical testing in over 230 patients to date, with a benign safety profile. Enterome SA (www.enterome.com) is a privately held clinical-stage biopharmaceutical company developing OncoMimics™, a breakthrough in in vivo immune therapies for cancer. The three most advanced product candidates have shown positive early data in Phase 2 clinical development in more than 230 patients across solid tumors and hematological malignancies, showing correlation between clinical efficacy and induced immunogenicity and a benign safety profile, activating large quantities of endogenous memory T-cells.
