Brief summary
A prospective, open-label, multi-center, Phase I/II study of L19IL2 in combination with Dacarbazine in patients with metastatic melanoma.
Detailed description
A prospective, open-label, multi-center, Phase I/II dose escalation study in which cohorts of 3-6 patients with metastatic melanoma will be assigned to receive escalating doses of L19-IL2 in combination with a fixed dose of Dacarbazine. After definition of MTD and RD during the phase II part of this study, 60 patients with Stage IV M1a and M1b melanoma will be randomized in a 1:1 ratio to receive open label the combination treatment at the RD (Arm 1) or DTIC monotherapy (Arm 2).
Interventions
DRUGL19IL2 - Ph I
During phase I part of the study, increasing dose of L19IL2 from one cohort to the next will be performed in steps of 160,000 IU/kg starting at 480,000 IU/kg (i.e., 0.48; 0.64; 0.80 MioIU/kg until MTD is reached).
DRUGL19IL2 at RD - Ph II
L19IL2 at RD will be administered to Arm 1 patients during phase II part of the study.
DRUGDTIC
Dacarbazine: 1 hour intravenous infusion on day 1 of each 21-cycle at a dosage of 1000 mg/m2 (fixed dose).

Adequate organ function: serum creatinine ≤ 1.5 x ULN, total bilirubin ≤ 30 mM/L (or mg/dL, ≤ 2.0 mg/dL), hepatic transaminases ≤ 2.5 x ULN, alkaline phosphatase ≤ 2.5 x ULN. 12. ANC count ≥ 1.5 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, hemoglobin \> 9 g/dL 13. Normal 12-lead ECG and normal bidimensional echocardiogram or MUGA 14.

Exclusion criteria
1. Pregnant or breastfeeding female 2. Primary ocular melanoma 3. Primary mucosal melanoma 4. Use of any investigational or other anti-cancer drug within 28 days or 5 half-lives, whichever is longer, preceding the first dose of DTIC and L19-IL2 5.
