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.

Outcome Measures

Primary Outcomes (1)

• PFS

  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)

  Every 12 weeks until subjects disease progressive, an average of 24 weeks

Secondary Outcomes (6)

  through study completion, an average of 1 year

• OS

  Approximately 3 years

• DRR

  through study completion, an average of 1 year

  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

Study Arms (2)

treatment group

EXPERIMENTAL

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

Control group

ACTIVE COMPARATOR

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)
