Brief summary: This is a two-stage phase I clinical trial with oncolytic viruses BS-006 in recurrent or metastasis cervical cancer patients who failed in second line treatment.

Detailed description: This trial includes accelerated dose-escalation stage and dose-expansion stage. An engineered modification oncolytic viruses, BS-006, derived from type II herpes simplex virus strain are planed to be injected into the tumor every two weeks until disease progression or unacceptable toxicity or withdrawn of consent or no lesion suitable for injection or death. In dose-escalation stage, there are three dose levels (1 million, 10 millions, 100 millions 50 % cell culture infectious dose (CCID50)/ml) . Treatment dose will escalate to next higher level if no dose limiting toxicity happens for one time of injection in 3 subjects. Maximal tolerable dose is defined as the highest dose with no more than one dose limiting toxicity and is recommended for dose expansion stage. In dose-expansion stage, 15 subjects will be enrolled. BS-006 viruses will be injected into proper tumor lesions every 2 weeks until disease progression or unacceptable toxicity or withdrawn of consent or no lesion suitable for injection or death. Radiology assessment will repeat every 6 weeks. Dose interruption, not reduction, is permitted in this stage.

5. Radiological confirmed progression after at least 2 lines prior treatment or intolerable toxicity events occur during the second or later line treatment: 1) Neoadjuvant or adjuvant chemotherapy for no less than 2 cycles should be regarded as a separate treatment line if disease progress within 6 months after treatment finish;2) Regional treatment such as brachytherapy, radiofrequency ablation and artery embolization therapy should not be considered as a treatment line; 3) Treatment shift due to toxicity without radiological progression should not be counted as a separate line;
6. At least one measurement lesion according to RECIST 1.1;
7. At least one lesion with maximum diameter is larger than 1cm and surgically accessibility;
8. Patients must have recovered from prior treatment related toxicity to CTCAE grade 1 or 0;

12. Patients must have fully recovered from suspected or diagnosed genital herpes beyond 3 months;
13. Patients or their legally authorized representative must be willing and able to sign the informed consent form (ICF) and to adhere to the protocol requirement;
14. Women of childbearing potential must agree to use highly effective contraceptive methods in while on study drug and for at least 3 months after the last injection of BS-006. The pregnancy test within 7 days prior to the first injection must be negative.

2. Central nerve system metastasis;
3. Lesions met the requirement outlined in the inclusion criteria are unsafe for injection evaluated by investigators;
4. Severe comorbidities of any organs, including but not limit to myocardial infarction within 6 months, unstable angina pectoris, congestive heart failure, grade 3 or higher hypertension per CTCAE, cardiac arrhythmias, uncontrolled diabetes, fever of unknown reason, active digest ulcer and chronic obstructive pulmonary disease;
5. History of central nervous system infectious or demyelinating disease;
6. Severe infectious disease requiring constant antibiotic treatment;
7. Systematic glucocorticoids use within 2 weeks or glucocorticoids need for a long term;
