Summary

The purpose of this study is to describe the safety, tolerability and early signs of efficacy of the antibody-cytokine fusion protein IL12-L19L19 in patients with advanced or metastatic solid carcinomas, after previous immune checkpoint blockade therapy.

The primary objective of the study is to evaluate the safety of IL12-L19L19 and to establish MTD in order to establish a recommended dose (RD).

The secondary objectives of the study are to assess early signs of efficacy, the determination of pharmacokinetic (PK) properties and the immunogenicity of IL12-L19L19.

Conditions

  • Advanced Solid Tumor
  • Metastatic Solid Tumor

Interventions

DRUG

IL12-L19L19

Part I - The dose escalation is designed with an initial accelerated phase followed by a standard 3+3 design. Cohorts contain one patient until first instance of moderate toxicity or a DLT in the DLT observation period (28 days). With the second occurrence of moderate toxicity or occurrence of a DLT the accelerated phase will be terminated and the dose escalation will continue with a 3+3 dose escalation. Initiation of the study treatment for an individual subject will occur not less than 7 days after initiation of the study treatment for the previous patient. Not more than 2 patients are to be treated simultaneously within their DLT observation period (i.e., Day 1 to Day 28). Part II - Dose expansion: Once the dose escalation is completed, additional 20 patients will be enrolled at the RD to better understand the safety profile and to explore early signs of efficacy in different disease indications.

DRUG

IL12-L19L19

Patients initially receive 8 consecutive administrations of IL12-L19L19 every week. At the end of this eight weeks treatment window, a tumor assessment is performed and those patients who achieve a clinical benefit (SD, PR, CR) may continue treatment with IL12-L19L19 as a biweekly maintenance therapy until disease progression, unacceptable toxicity, withdrawal of consent, at the discretion of the investigator or up to 1 year from study treatment start.
