ClinConnect Summary

This is a non-randomised, single-centre Phase I/II study of the combination of the oncolytic virus, TVEC, administered by intra-tumoural (i.t.) injection in combination with isolated limb perfusion with melphalan and tumour necrosis factor in patients with advanced extremity tumours.

The safety of T-VEC administered by i.t. injection followed by isolated limb perfusion will be assessed in an initial safety run in comprised of six subjects as described below.

Cohort 1: The first subject will be recruited and will receive an initial dose of T-VEC 4-6 weeks prior to isolated limb perfusion.
