入选标准
- •Male or female age ≥ 18 years with histologically confirmed diagnosis of melanoma and unresected stage IIIB, IIIC, IVM1a, IVM1b, or IVM1c regardless of prior line of therapy. Subject is candidate for intralesional therapy administration into cutaneous, subcutaneous, or nodal disease and must also have measurable disease, serum lactate dehydrogenase ≤ 1.5 x upper limit of normal, and Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and adequate hematologic, hepatic, and renal organ function.
排除标准
- •Subject must not have clinically active cerebral metastases, greater than 3 visceral metastases (this does not include lung metastases or any nodal metastases associated with visceral organs) or any bone metastases melanoma, primary ocular or mucosal melanoma, history or evidence of symptomatic autoimmune pneumonitis, glomerulonephritis, vasculitis, or symptomatic autoimmune disease, or evidence of immunosuppression for any reason. Subject known to have acute or chronic active hepatitis B or hepatitis C infection, or human immunodeficiency virus infection will also be excluded. Subject who has active herpetic skin lesions or prior complications of herpes simplex virus type 1 ( HSV-1) infection (eg, herpetic keratitis or encephalitis), and/or requires intermittent or chronic systemic (intravenous or oral) treatment with an antiherpetic drug (eg, acyclovir), other than intermittent topical use will also be excuded. Subject must not have received previous treatment with talimogene laherparepvec.
研究组 & 干预措施
Talimogene Laherparepvec
Talimogene laherparepvec was administered by intralesional injection into injectable cutaneous, subcutaneous, and nodal lesions at an initial dose of 10⁶ plaque-forming units (PFU) per mL followed by a dose of 10⁸ PFU/mL 21 days after the initial dose and every 14 days thereafter.
Participants were treated with talimogene laherparepvec until they achieved a complete response (CR), all injectable tumors had disappeared, clinically relevant (resulting in clinical deterioration or requiring change of therapy) disease progression per modified World Health Organization (WHO) response criteria beyond 6 months of therapy, or intolerance of study treatment, whichever occurred first.

结局指标
主要结局
Percentage of Participants With Detectable Talimogene Laherparepvec Deoxyribonucleic Acid (DNA) During the First Three Cycles
时间窗: Cycles 1 and 2 on days 1 (pre-dose and 1, 4, and 8 hours post-dose), 2, 3, 8, and 15 (cycle 1 only), cycle 3 on day 1 (pre-dose) and day 8, and cycle 4 on day 1 (pre-dose).
Talimogene laherparepvec DNA was measured using a quantitative polymerase chain reaction (qPCR) method. The percentage of participants with detectable talimogene laherparepvec DNA in blood or urine at any time during cycles 1 to 3 is reported. The first cycle was 21 days in length, and subsequent cycles were 14 days in length.
