Intratumoral Injection of Recombinant Human Endostatin Adenovirus (EDS01) for the Treatment of Recurrent or Metastatic Head and Neck Tumors
A Phase I Clinical Trial of Intratumoral Injection of Recombinant Human Endostatin Adenovirus (EDS01) Combined With Toripalimab for the Treatment of Recurrent or Metastatic Head and Neck Tumors
West China Hospital
9 participants
Mar 27, 2026
INTERVENTIONAL
Conditions
Summary
This single-center, Phase 1 study is evaluating the safety, tolerability, and preliminary antitumor activity of recombinant human endostatin adenovirus injection (EDS01) given by intratumoral injection in combination with toripalimab in adults with recurrent or metastatic head and neck tumors, including nasopharyngeal carcinoma, whose disease has progressed after platinum-based systemic therapy or who are not suitable for further platinum treatment. A total of 9 participants will be enrolled in 3 planned dose groups of EDS01. EDS01 will be injected directly into an accessible tumor lesion on Days 0 and 7, and toripalimab 240 mg will be administered intravenously on Day 1 of each treatment cycle for up to 4 cycles, unless disease progression or unacceptable toxicity occurs. The study will evaluate treatment-related adverse events as well as preliminary efficacy outcomes, including tumor response, disease control, and time to progression, using clinical assessments, laboratory tests, imaging, and follow-up after treatment.

Interventions
Recombinant human endostatin adenovirus injection (EDS01) is administered by intratumoral injection into an accessible tumor lesion on Days 0 and 7 of each 21-day cycle. Three planned dose levels are evaluated across study cohorts: 1.0×10\^11 VP. Treatment may continue for up to 4 cycles unless disease progression or unacceptable toxicity occurs.
Recombinant human endostatin adenovirus injection (EDS01) is administered by intratumoral injection into an accessible tumor lesion on Days 0 and 7 of each 21-day cycle. Three planned dose levels are evaluated across study cohorts: 5.0×10\^11 VP. Treatment may continue for up to 4 cycles unless disease progression or unacceptable toxicity occurs.
