Qbiotics, page-103

There is a slide on pg 11 of the annual report depicting treatment of metastatic melanoma on forearm using TT as monotherapy and where keytruda had already been used for treatment

Previous treatment - keytruda 9 week washout prior to TT dosing
Complete response - Achieved by day 30 in in 3 injected and 4th non injected tumours (possible abscopal/ bystander effect)
No adverse effects reported, or additional treatment, wound intervention required.

Reason enough to be 'enthusiastic'
