|Official Title:||A Dose Finding Pharmacokinetic Study of the Tumour-targeting Human L19IL2 Monoclonal Antibody-Cytokine Fusion Protein in Patients With Advanced Solid Tumours|
- To determine the maximum tolerated dose (MTD) and recommended dose (RD) of the human L19IL2 fusion-cytokine. [ Time Frame: 21 days ]
- To determine the pharmacokinetic profile. [ Time Frame: 5 days ]
- To determine the qualitative and quantitative toxicity profile. [ Time Frame: 21 days ]
- To assess the presence of anti-fusion protein antibodies in treated patients. [ Time Frame: 18 weeks ]
- To evaluate the safety profile of repeated administrations of L19IL2 in patients treated at the RD. [ Time Frame: 1 year ]
- To identify early signs of antitumour activity. [ Time Frame: 1 year ]

Route: i.v. infusion (60 min) Patients will receive a minimum of 2 cycles of treatment. Each cycle is comprised of treatment on Days 1, 3 and 5 followed by a 16 days rest (1 cycle= 21 days). Patients may receive up to 4 further cycles of treatment (max. of 6 cycles in total). Patients will be initially recruited into the study in cohorts of 3 and the starting dose of L19IL2 will be 5 Mio IU IL2 equivalent. Five steps of dose escalation are planned: 5, 10, 20, 30 and 40 Mio IU IL2 equivalent). After the MTD has been established, the RD will be determined. A further 12 patients (with RCC) will receive the RD dose for a minimum of 2 cycles. For patients in the RD part of the study, patients can switch to maintenance therapy. Maintenance therapy consists of 15 Mio IU IL2 every 2 weeks. The maximum duration of the study for a patient is 12 months.
This is an open-label, non-randomised, multicentre, Phase I/II study to assess safety, pharmacokinetics (PK), and early signs of activity of L19-IL2 monotherapy.
In the first part of the study, there will be 5 dose escalation steps in sequential cohorts of patients with advanced solid tumours. In the second part of the study, patients with advanced RCC will be given a fixed dose of L19IL2 at the RD.
