For most advanced solid tumors, current therapy is inadequate at improving quality of life, slowing progression of disease, prolonging survival, and providing a cure. Hence, there is a continuous need for innovative, safer and more effective anti-cancer therapies. Our study is based on the dependence receptor paradigm and the associated therapeutic strategy. In preclinical models, preventing Netrin-1 interaction with its receptors is sufficient to trigger Netrin-1-expressing tumor cell death in vitro as well as tumor growth and metastasis inhibition in vivo. This indicates that a therapeutic approach based on Netrin-1/Netrin-1 receptors interaction inhibition is both feasible and promising. NP137 is a "first-in-class" humanized monoclonal antibody targeting the Netrin-1 ligand, a secreted protein recently described as a driver of tumor initiation and progression. NP137 demonstrated anti-tumor activity as a single agent in several pre-clinical models of cancer, including breast and lung cancer. Taken together, several studies strongly support the rational for preclinical development and clinical evaluation of a highly potent and selective anti-Netrin-1 antibody in cancer patients. The proposed study is an open label, multicenter, Phase I dose escalation study to assess the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) and preliminary anti-tumor activity of NP137 administered every 2 weeks (Q2W) as single agent in patients with locally advanced or metastatic solid tumors. This trial will be the First in Human (FIH) study for NP137; there is no clinical experience with this antibody in the clinic. The study consists of 3 parts: Part 1) a dose escalation part to define the Maximum tolerated dose and the Recommended Phase II dose (MTD /RP2D) of NP137 as well as to research some PD biomarkers (Biological collection cohorts) - This part is now completed with Last Patient In on December 20th 2018 - Part 2) an expansion part#1 to investigate NP137 clinical activity as a single agent by collecting the 3-month objective response rate (ORR3m). Part 3) an expansion part#2 to investigate NP137 clinical activity as a single agent by collecting the 3-month objective response rate (ORR3m) in RH+ patients with endometrial carcinoma.
