Time frame: Tumor response was assessed at weeks 12 and 24 and then at least every 3 months up to the end of treatment; median duration of treatment was 23.1 weeks (range: 3 to 141 weeks).
Duration of response (DOR) was calculated only for those participants with an objective response and defined as the longest interval from an initial objective response (complete response or partial response) to disease progression per the modified WHO criteria or death, whichever occurred earlier; otherwise, DOR was censored at the last evaluable tumor assessment for participants who did not die or progress.

Durable response rate is defined as the percentage of participants with a complete response or partial response maintained continuously for at least 6 months (183 days).
Complete response: disappearance of all index and non-index lesions.
Partial Response:≥ 50% reduction in size of all index lesions and any new measurable lesions.
Time frame: From first dose until 60 days after last dose of talimogene laherparepvec; The median actual follow-up time was 28.9 weeks (range: 4 to 151 weeks).
Overall Survival (OS) was defined as the interval from first dose of talimogene laherparepvec to death from any cause; participants still alive were censored at the last known alive date.
Time frame: From the first administration of talimogene laherparepvec up to 30 days after the last administration of talimogene laherparepvec; median duration of treatment was 23.1 weeks (range: 3 to 141 weeks).
The Common Terminology Criteria for Adverse Events version 3.0 was used to grade severity of adverse events, based on the following general guideline: Grade 1 = Mild AE Grade 2 = Moderate AE Grade 3 = Severe AE Grade 4 = Life-threatening or disabling AE Grade 5 = Death related to AE. A serious adverse event was defined as an adverse event that meets at least 1 of the following serious criteria:
Treatment-related adverse events (TRAEs) are defined as adverse events possibly caused by talimogene laherparepvec, as assessed by the investigator.
