Brief Summary:

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.

Malignant Melanoma, Skin Drug: L19IL2+L19TNF Phase 2

Detailed Description:

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.

Arm Intervention/treatment
Experimental: L19IL2 + L19TNF
One arm, intratumoral injections of 10 Mio IU of L19IL2 and 312 μg L19TNF. Weekly administration for all combined leasions
Drug: L19IL2+L19TNF
Patients will be treated with intratumoral injections of 10 MioIU L19IL2 and 312μg L19TNF once weekly for up to 4 weeks.

Primary Outcome Measures :
  1. Rate of patients with complete response (CR) of L19IL2 treated Index/Non-Index lesions at week 12. [ Time Frame: Week 12 ]

Secondary Outcome Measures :
  1. Efficacy of L19IL2/L19TNF treated Index/non treated lesions [ Time Frame: week 12, 24 and 36 ]
    • Rate of patients with CR, PR and SD of all metastases at week 12, 24 and 36 (objective response rate according to RECIST v 1.1)
    • Duration of objective response and disease control of all metastases
    • Median overall survival (mOS)

  2. Overall survival (OS) [ Time Frame: 1 year ]
  3. Safety of the combination treatment with L19IL2 and L19TNF [ Time Frame: 1 year ]
    Evaluation of the type and the number of adverse events eventually present

  • History of HIV infection or infectious hepatitis B or C
  • Presence of active infections (e.g. requiring antimicrobial therapy) or other severe concurrent disease, which, in the opinion of the investigator, would place the patient at undue risk or interfere with the study.
