Clinical Trial Summary

An Open Label, Multi-Center, Dose Escalation/Expansion, Phase 1/1b Study of IMU 201 (PD1-Vaxx), a B-Cell Immunotherapy as monotherapy or in combination with atezolizumab with or without chemotherapy, in Adults with Non-Small Cell Lung Cancer (IMPrinter).


Clinical Trial Description

Investigational Medicinal Product, IMU-201, consists of drug substance, APi2568, which is a B-cell epitope (amino acids 92-110 from PD-1) linked to a promiscuous T-cell epitope (amino acid residues 288-302 from measles virus fusion protein) via a 4-amino acid linker (Gly-Pro-Ser-Leu), and combined with Water for Injection (WFI) forms the drug product, IMU-201, which becomes PD1-Vaxx when emulsified with excipient Montanide ISA 720 VG. It is hypothesized that a polyclonal induced B-cell antibody response will be more effective or as effective with improved safety over current monoclonal antibody therapy. This phase 1/1b study is an open-label dose escalation/dose expansion study designed to assess the safety, tolerability, immunogenicity and efficacy of IMU-201 (PD1-Vaxx). Phase 1 monotherapy dose-escalation of IMU-201 (PD1-Vaxx), will enroll approximately 9-18 patients and establish the optimal monotherapy biological dose (mBOD). Once established, the dose cohort will be expanded to enroll additional 10 patients at the mBOD dose level. Phase 1b, a combination dose-escalation of IMU-201 (PD1-Vaxx) with atezolizumab and with or without chemotherapy, will enroll approximately 18-36 patients and establish the optimal combotherapy biological dose (cBOD). Once established, the dose cohort will be expanded to enroll additional 30 patients at the cBOD dose level. ;
