• Actual Enrollment: 9 participants
• Allocation: Non-Randomized
• Intervention Model: Single Group Assignment
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: An Open-Label, Uncontrolled, Single Center, Phase I Trial to Assess the Safety of VM206RY in Subjects With Expression of Her2 in Breast Cancer

Arms and Interventions

Arm	Intervention/treatment
Experimental: CohortⅠ; VM206DNA 6mg and VM206Ad 3*10^9VP injected into the brachial muscle	Biological: VM206DNA; Biological: VM206Ad
Experimental: CohortⅡ; VM206DNA 12mg and VM206Ad 3*10^9VP injected into the brachial muscle	Biological: VM206DNA; Biological: VM206Ad
Experimental: CohortⅢ; VM206DNA 24mg and VM206Ad 3*10^9VP injected into the brachial muscle	Biological: VM206DNA; Biological: VM206Ad

Outcome Measures

Primary Outcome Measures :

1. Adverse events (including serious adverse events and adverse events lead to treatment discontinuation) will be described according to severity and to their relationship with the study drug and injection procedure. [ Time Frame: Up to 24 weeks ]

Secondary Outcome Measures :

1. Dose Limiting Toxicity (DLT) and Maximum Tolerated Dose (MTD) [ Time Frame: Up to 8 weeks ]
   DLT was defined as adverse events higher than grade 3 based on NCI CTCAE version 4.0 with respect to their relationship with the study drug and injection procedure until 2 weeks after final injection. MTD was defined as the highest dose evaluated for which less than 1/3 of the participants experienced DLT.
2. Analysis of HER2 specific antibody formation in plasma at pre and post injection using ELISA or FACS [ Time Frame: Up to 24 weeks ]
3. Analysis of HER2 specific CTL response on PBMC at pre and post injection using IFN-gamma ELISPOT [ Time Frame: Up to 24 weeks ]
4. Assessment of tumor response based on the Response Evaluation Criteria in Solid Tumors (RECIST version 1.1) [ Time Frame: Up to 24 weeks ]
5. Change of HER2 level in plasma at pre and post injection using ELISA [ Time Frame: Up to 24 weeks ]
6. Analysis of GM-CSF level in plasma at pre and post injection using ELISA [ Time Frame: Up to be confirmed as negative ]
7. Analysis of VM206Ad in whole blood at pre and post injection using Q-PCR [ Time Frame: Up to be confirmed as negative ]
