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.

—无需化疗、不开刀，精准杀死癌细胞 2025年12月29日，据日本《日经新闻》报道：日本冈山大学联合团队成功研发出一种“只攻击癌细胞”的病毒治疗药物，并已获得日本厚生劳动省申请上市审批。该疗法主要用于治疗食道癌，将成为全球首个获批的溶瘤病毒食道癌治疗药物，为无法接受化疗或手术的患者带来新的希望。 🔬 什么是病毒疗法？ 这款新型治疗药物名为 “Telomelysin（特罗美来新）”，是一种经过基因改造的腺病毒。研究团队对普通感冒病毒进行了精准改造，使其只能在癌细胞中复制增殖，而不会伤害正常细胞。 一旦进入肿瘤内部，病毒会在短时间内大量复制，直接破坏癌细胞结构，并进一步增强放射线治疗的效果，相当于在肿瘤内部“引爆”。 🧪 临床试验效果如何？ 研究团队自2002年起开展相关研究，并于2020年启动针对无法接受抗癌药物或手术的食道癌患者的临床试验。治疗方式为： • 在放射线治疗期间 • 通过内镜将病毒直接注入肿瘤部位 • 共进行3次给药 结果显示，在36名患者中，18个月后有18人癌症完全消失，消失率高达50%。 作为对比，日本癌症治疗权威的国立癌症研究中心数据显示： 👉 如果只是单纯放射线治疗的癌症消失率仅20%。 这意味着，新疗法在疗效上具有明显优势。 🌱 副作用更小，患者负担更低 与传统抗癌治疗相比，这种病毒疗法具有多项优势： • ❌ 不引起明显恶心、呕吐 • ❌ 不会导致免疫力显著下降 • ❌ 无需外科切开手术 • ✅ 通过口腔内镜操作，创伤极小 对体力较弱或高龄患者而言，安全性和耐受性更高。 🏥 何时能用上？ 此次上市申请由冈山大学校办的生物医药公司 Oncolys BioPharma 提交，未来将由富士胶片富山化学负责销售。 如果顺利，最快有望在2026年实现临床应用。 🔭 不止于食道癌 该研究负责人、冈山大学消化外科教授 藤原俊义 表示，未来希望将该病毒疗法拓展至其他癌种，比如胰腺癌，转移的乳腺癌等治疗方式的联合应用，以获得更强的整体治疗效果。 ✨开启希望之光 溶瘤病毒疗法被认为是继手术、放疗、化疗、免疫治疗之后，癌症治疗的重要新方向。此次食道癌领域的突破，不仅代表技术创新，也意味着更多“无路可走”的患者或将迎来新选择。 中国目前也有一些医院在研究该治疗方法五，但是还没获得批准。希望以后国内也有好的消息。
