Intratumoral Administration of L19IL2/L19TNF
|ClinicalTrials.gov Identifier: NCT02076633|
Recruitment Status : Completed
First Posted : March 3, 2014
Last Update Posted : May 27, 2015
This Phase II study is an uncontrolled, multicenter, prospective study for patients with malignant melanoma of the skin in clinical stage III or stage IV M1a.
Twenty Patients will be treated with a mixture of L19IL2 and L19TNF once weekly for up to 4 weeks.
The dose will be distributed among the lesions via multiple intralesional injections.
The proportion of patients with complete response at week 12 will be calculated.

L19IL2 is a recombinant fusion protein composed of a fully human recombinant monoclonal antibody (L19) and the human recombinant interleukin-2 (IL-2).
IL2, is a potent stimulator of the immune response. It has a central role in the regulation of T cell responses and effects on other immune cells such as natural killer cells, B cells, monocyte/macrophages and neutrophils. IL2 can induce tumor regression through its ability to stimulate a potent cell-mediated immune response in vivo.
L19TNF is a recombinant fusion protein composed of a fully human recombinant monoclonal antibody (L19) and the human tumor necrosis factor-alpha, a primary mediator of immune regulation and inflammation.
As an anti-tumor agent, TNF exerts its major effects via a preferential toxicity for the endothelial cells of the tumor-associated vasculature and an increase of the antitumor immune response. Given at sufficient doses (e.g. intratumorally or in the ILP setting with melphalan), TNF causes significant tumor shrinkage in solid cancer subjects.
This phase II signal generating study is designed to test the efficacy and safety of an intratumorally administered mixture of L19IL2 + L19TNF in patients suffering from metastatic melanoma. It is well documented that the intratumoral administration of IL-2 leads to a high response rate and unexpectedly favorable longtime outcome and several tumor responses have been observed in clinical trials of Philogen, both using intratumorally administered L19IL2 and L19TNF in the ILP setting.
Preclinical data produced within the Philogen group now suggest that the intratumoral administration of a mixture of L19IL2 and L19TNF could be even more effective. After only one intratumoral administration of a mixture of L19IL2 and L19TNF tumors disappeared completely while neither L19IL2 nor L19TNF monotherapy was nearly as effective.
