Effectiveness of Interferon-Beta for pleural mesothelioma

Clin Cancer Res. 2007 Aug 1;13(15):4456-66, A Phase I Clinical Trial of Single-Dose Intrapleural IFN-{beta} Gene Transfer for Malignant Pleural Mesothelioma and Metastatic Pleural Effusions: High Rate of Antitumor Immune Responses, Sterman DH, Recio A, Carroll RG, Gillespie CT, Haas A, Vachani A, Kapoor V, Sun J, Hodinka R, Brown JL, Corbley MJ, Parr M, Ho M, Pastan I, Machuzak M, Benedict W, Zhang XQ, Lord EM, Litzky LA, Heitjan DF, June CH, Kaiser LR, Vonderheide RH, Albelda SM.

This study evaluated single-dose intrapleural interferon-beta gene transfer in patients with malignant pleural mesothelioma and metastatic pleural effusions.

Subjects were evaluated for (a) toxicity, (b) gene transfer, (c) humoral, cellular, and cytokine-mediated immune responses, and (d) tumor responses.

Intrapleural interferon-beta was generally well tolerated. Gene transfer was documented in 7 of the 10 patients by demonstration of IFN-beta message or protein. Antitumor immune responses were elicited in 7 of the 10 patients and included the detection of cytotoxic T cells (1 patient), activation of circulating natural killer cells (2 patients), and humoral responses to known (Simian virus 40 large T antigen and mesothelin) and unknown tumor antigens (7 patients). Four of 10 patients showed meaningful clinical responses at day 60.

Intrapleural interferon-beta is a potentially useful approach for pleural mesotheliomia patients and should be investigated further for overall clinical efficacy.
