Brief Summary:

This study is being performed to evaluate the safety and efficacy of Dacarbazine and OrienX010 therapy in Untreated Patients With Unresectable Stage IIIb/IIIc or Stage IV(Mla/Mlb) Melanoma.

The study will be conducted in about 6 centres in China and total 165 patients will be enrolled. All eligible Patients will be randomized between Dacarbazine and OrienX010 in a 1:2 ratio, so 1/3 (55) patients will receive the Dacarbazine and 2/3 (110) patients will receive the OrienX010.

During the treatment phase, the patient will receive OrienX010 administration once biweekly or Dacarbazine once every 3 week until to the end of treatment (EOT). The duration of safety follow-up for adverse events (AEs) and serious adverse events (SAEs) will be to 90 days after the end of treatment. The details please refer to study schema.

For patients who have completed the study treatment and no disease progression, follow-up visits will take place every 3 months after the end of treatment visit until the occurrence of disease progression. If disease progression occurred, the investigator will collect the anticancer treatment information and survival of individuals until 80% death event.

After the end of study, if patient want to continue receiving the OrienX010 treatment and judged by investigator, sponsor will provide OrienX010 and Dacarbazine for free until disease progression/death or OrienX010 on marketing launch.

Arm Intervention/treatment
Experimental: treatment group

OrienX010 will be administered once every two weeks by intratumoral injection. The treatment dose , depends on the patient's tumour size, The maximum dose of OrienX010 in at each treatment , the expected accumulated dose in 10 mL. The investigator should be confirmed the injectable tumor size and adequate dose within 24 hours prior to treatment.

OrienX010 treatment will be continuous and extend from first dose of study medication until to complete response, clinical related progression disease (PDr), untolerated toxicities, lost to follow up, death or meet end of treatment criteria.

Biological: OrienX010 injection

OrienX010 to be used in this study have been developed and manufactured by OrienGene Biotechnology Ltd.

Dacarbazine to be used in this study was manufactured by Sinopharm A-Think Pharmaceutical Co., Ltd.

Other Name: Recombinant Human GM-CSF Herpes Simplex Virus Injection

Active Comparator: Control group
Dacarbazine will be administered once every three weeks by intravenous 1000mg/square meter. Dacarbazine treatment will be continuous and extend from first dose of study medication until to progression disease (PD), untolerated toxicities, lost to follow up, death or meet end of treatment criteria.
Drug: Dacarbazine (DTIC)
Dacarbazine to be used in this study was manufactured by Sinopharm A-Think Pharmaceutical Co., Ltd.

Primary Outcome Measures :
  1. PFS [ Time Frame: Every 12 weeks until subjects disease progressive, an average of 24 weeks ]
    Progression-free survival (PFS), defined as the first documentation of objective disease progression, according to Response Evaluation Criteria in Solid Tumors (RECIST v.1.1)

Secondary Outcome Measures :
  1. DCR [ Time Frame: through study completion, an average of 1 year ]
    Disease Control Rate (DCR), defined as the proportion of subjects with complete response, partial response, or stable disease for more than 3 months, according to RECIST v.1.1 criteria

  2. ORR [ Time Frame: through study completion, an average of 1 year ]
    Objective Response Rate (ORR), defined as complete or partial tumor response, according to RECIST v.1.1 criteria

  3. OS [ Time Frame: Approximately 3 years ]
    Overall survival defined as the time from randomization to death from any cause

  4. DRR [ Time Frame: through study completion, an average of 1 year ]
    Durable response rate (DRR) defined as objective response lasting continuously ≥ 6 months

  5. Quality of life assessment [ Time Frame: every 6 weeks up to 24 weeks, and then every 12 weeks up to the date of end of treatment,an average of 24 weeks ]

    Use EORTC QLQ-C30 to assess quality of life. The EORTC(European Organization for Research and Treatment of Cancer) QLQ-C30 (Quality of Life Questionnaire C30), is a cancer-specific quality of life instrument applicable to a broad range of cancer patients.

    QLQ-C30 contain 15 domain, The standard score for each domain from 0-100. higher scores mean a worse outcome.

  6. Incidence of treatment-related SAE and AE [ Time Frame: From date of enrolling to 90 days after end of treatment ]
    Number of participants with treatment-related serious adverse events (SAE) and adverse events that assessed by CTCAE v4.03
