AgentPhaseStatusStudy TypeDescription

IFN- 2 (NCT00004897)Active, not recruiting( 15–45)Open-label trialPatients with stage I–III esophageal cancer receive combination chemotherapy and recombinant IFN- followed by surgery and/or RT
3 (NCT00054561)Completed ( )Multicenter randomized controlled trialTo compare the combination of isotretinoin, recombinant IFN- , and vitamin E with observation only in patients with stage III or IV HNSCC

Pegylated IFN- 2b2 (NCT00276523)Completed ( )Randomized controlled trialPegylated IFN- 2b at 3 different dose levels is compared with no treatment prior to resection of stage II–IV HNSCC

IL-22 (NCT00006033)Completed ( )Multicenter open-labelTo compare IL-2 gene with methotrexate in the treatment of recurrent or refractory stage III/IV HNSCC
3 (NCT00002702)Recruiting ( )Multicenter randomized, controlled trialTo compare surgery and RT with and without rIL-2 in patients with SCC of the mouth or oropharynx

IL-121/2 (NCT00004070)Active, not recruiting ( 28–34)Multicenter rising-dose studyPatients with unresectable, recurrent, or refractory HNSCC receive IL-12 gene twice during week 1 and once weekly during weeks 2–7

ALT-801 (a recombinant fusion protein with an IL-2 component)1 (NCT00496860)Recruiting ( )Multicenter dose-escalation studyTo determine the MTD of ALT-801 in previously treated patients with progressive metastatic malignancies, including HNC

IRX-22 (NCT00210470)Closed ( )Multicenter open-label trialStudy of IRX-2 with cyclophosphamide, indomethacin, and zinc in patients with newly diagnosed, resectable stage II–IV HNSCC. The study is being conducted to confirm the safety and biological effect of the IRX-2 regimen in the same population to be studied in a planned randomized phase 3 trial. The primary focus will be on observations made from the start of treatment through the planned surgical resection of the primary tumor.

HNC: head and neck cancer; HNSCC: head and neck squamous cell carcinoma; IFN: interferon; IL: interleukin; MTD: maximum tolerated dose; RT: radiotherapy.
