Abstract

Purpose: TNFerade is a second-generation replication-deficient adenovector carrying a transgene encoding human tumor necrosis factor α under control of a radiation-induced promoter. The objective of this study was to assess the tolerance of combining TNFerade and radiation therapy in patients with soft tissue sarcomas of the extremity. Experimental Design: TNFerade was administered in combination with single-daily fractionated radiation therapy in 14 patients with soft tissue sarcoma of the extremities. Three escalating dose levels of TNFerade (4 × 109 -4 × 1011 particle units) were planned, given in 1 log increments by intratumoral injections, twice weekly during week 1 and once weekly during weeks 2-5 of radiation therapy. Results: TNFerade was with well tolerated with no dose-limiting toxicities noted. Grade 1-2 chills (50.0%), fever (43.0%), fatigue (36.0%), and flu-like symptoms (21.0%) were the most common side effects. Serum-tumor necrosis factor α levels were low in all of the patients (<15 pg/mL). No patients had virus-detected blood, sputum, or urine cultures. Of the 13 evaluable patients, 11 received TNFerade preoperatively, and 2 received the treatment for palliation. Eleven patients (85%) showed objective or pathological tumor responses (2 complete and 9 partial), and 1 had stable disease. Partial responses were achieved despite some of these tumors being very large (up to 675 cm2). Of the 11 patients who underwent surgery, 10 (91%) showed a pathological complete response/partial response. Conclusion: TNFerade + radiation therapy was well tolerated in the treatment of patients with soft-tissue sarcoma of the extremity. The high number of objective responses observed warrants additional studies of this approach in a larger controlled prospective trial.
