OH2 Injection in Solid Tumors

Get Involved

Study Purpose

This phase I study evaluates the safety and efficacy of OH2 as single agent or in combination with Keytruda, an anti-PD-1 antibody, in patients with malignant solid tumors (Melanoma). OH2 is an oncolytic virus developed upon genetic modifications of the herpes simplex virus type 2 strain HG52, allowing the virus to selectively replicate in tumors. Meanwhile, the delivery of the gene encoding human granulocyte macrophage colony-stimulating factor (GM-CSF) may induce a more potent antitumor immune response.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 75 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. The non-operative stage III or stage IV malignant tumor patients with clear diagnosis by pathology and/ or cytology; breast cancer, gastrointestinal adenocarcinoma, liver cancer, cervical cancer, malignant melanoma, head and neck tumors, Priority inclusion in soft tissue sarcomas (mainly for melanoma patients at the dose extension phase). 2. The absence of a conventional effective treatment or treatment failure or recurrence by a conventional method. 3. Male or female patients, aged 18 ≤ 75 years (including boundary value), general physical condition score ECOG 0 ≤ 1, expected survival time more than 3 months. 4. Prior anti-tumor treatment (including endocrine, chemical/ radiotherapy,targeted therapy) was over 4 weeks (more than 6 weeks of discontinuation using nitroso-and mitomycin-based chemotherapy) and was recovered to grade 1 from the side effects of prior treatment. 5. Those who have undergone major surgery will have to undergo surgery for four weeks. 6. There is at least one measurable lesion that is suitable for intratumoral injection. According to RECIST version 1.1, it is determined that at least once the CT or MRI examination shows the tumor lesion, it is possible to measure the tumor focus. The measured tumor focus is defined as the longest diameter ≥ 10 mm and the scanning thickness is not more than 5.0 mm. For lymph node lesions, the short diameter is ≥ 15 mm. 7. There is no serious dysfunction of the main organs. 8. (a) WBC≥3.0×109／L，ANC≥2.0×109／L ，PLT≥100×109／L，Hb≥90 g/L； (b) BUN and Scr. were in the upper limit of 1.5 times of the normal value; (c) TBIL≤ 1.5 times the upper limit of the normal value. (d) ALT and AST ≤ 2.5 times the upper limit of normal value; The value of patients with liver metastasis did not exceed 5 times the upper limit of normal value. (e) Coagulation function is normal (PT and APPT are within 1.5 times of the upper limit of normal value). 9. Female subjects and their spouses received effective contraceptives during and within 3 months of treatment. 10. Subjects with herpes in the reproductive organs needed three months after the end of herpes. 11. The informed consent was voluntarily signed and the expected compliance was good.

Exclusion Criteria:

(use of combination drugs only) 4. Treated with PD-1/PD-L1 or PD-L2 monoantigens or inhibitors that have been used or used in the past. (use of combination drugs only) 5. Autoimmune diseases requiring systemic treatment (e.g. steroids or immunosuppressants) during the first 2 years of treatment, such as autoimmune pneumonia, glomerular nephritis, vasculitis and other symptoms of autoimmune diseases; Except for wind or child asthma. (use of combination drugs only) 6. Have uncontrolled primary or brain metastatic tumors. 7. Suffering from uncontrolled mental illness, infectious diseases. 8. The lesions cannot meet the requirements of injection capacity in the tumor body. 9. Pregnant or lactating women. 10. Other experimental therapies or antiviral therapy are used or are being used within 4 weeks of treatment. 11. Other clinical studies have been taken in the past 4 weeks. 12. Allergy to herpes virus and drug ingredients. 13. The researchers believe that there is any reason why the patient is not suitable to participate in this trial.

Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1/Phase 2
