First in Human Study to Test the Safety and Preliminary Efficacy of PPSGG in Patients With Anti-MAG Neuropathy

Anti-MAG Neuropathy Clinical Trial

Official title: First in Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of PPSGG (PN-1007) in Anti-MAG Neuropathy Patients

Status Terminated

Clinical Trial Summary

In this study, the new drug called PPSGG (PN-1007) will be tested. Preliminary studies conducted in animals suggest PPSGG (PN-1007) might be a good treatment for reducing levels of anti-MAG antibodies in patients with anti-MAG neuropathy.

This is the first research of PPSGG (PN-1007) in people and its main purpose is to test its safety and acceptability in patients. In this study it will be examined how the drug is changed by and removed from the body and checked for signs that the drug may be truly effective against anti-MAG neuropathy. PPSGG (PN-1007) will be tested at several different doses.

Clinical Trial Description

PPSGG (PN-1007) is intended to bind anti-MAG IgM autoantibodies, the underlying cause of anti-MAG neuropathy, in a highly selective manner, resulting in their neutralization and removal from the circulation. This allows specific targeting of anti-MAG IgM in the circulation and circumvents unspecific immunosuppression associated with current treatment strategies.

This is a Phase I/IIa, First in Human (FiH), multicenter, single and multiple ascending dose escalation trial of PPSGG (PN-1007), an antibody scavenger of pathogenic anti-MAG immunoglobulin M (IgM) autoantibodies for treatment of anti-MAG neuropathy. The aim of the study is to assess the safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of PPSGG (PN-1007) in a SAD and a MAD phase in an adaptive trial in anti-MAG neuropathy patients. ;
