Patients underwent treatment at Lesion A with radiation (XRT) with 2 Gy per day on Days 1 and 2. Starting after XRT on Day 2, patients received five weekly intratumoral injections at the treated site (Lesion A) with the TLR9 agonist, SD-101. Treatment response was evaluated 90-day and 180-days post-treatment and every 6 months thereafter. FNA biopsies were collected pretreatment (Day 1) and post-initial treatment (Day 9) at Lesion A and, if available, at a single distal site, Lesion B.
