Study of [11C]CPPC to Assess the Safety and Tolerability in Patients With ALS

Amyotrophic Lateral Sclerosis Clinical Trial

Official title:
A Phase 1 Study to Assess the Safety and Tolerability of PET Imaging With [11C]CPPC [5-cyano-N-(4-(4-[11C]Methylpiperazin-1-yl)-2-(Piperidin-1-yl)Phenyl)Furan-2-carboxamide] Radioligand in Patients With Amyotrophic Lateral Sclerosis

Clinical Trial Summary

The goal of this study is to evaluate the safety of using the [5-cyano-N-(4-(4-[11C]Methylpiperazin-1-yl)-2-(Piperidin-1-yl)Phenyl)Furan-2-carboxamide] ([11C]CPPC) radiotracer in positron emission tomography (PET) imaging of people with amyotrophic lateral sclerosis (ALS). The investigators are also interested to see whether use of this radiotracer reveals imaging differences between patients with ALS and healthy patients.

Clinical Trial Description

This is a Phase 1 study of safety and tolerability of an investigational radiotracer drug called [5-cyano-N-(4-(4-[11C]Methylpiperazin-1-yl)-2-(Piperidin-1-yl)Phenyl)Furan-2-carboxamide] ([11C]CPPC). A radiotracer is a substance that chemically marks certain structures in the body. In this case, [11C]CPPC highlights structures expressing colony stimulating factor receptor (CSF1R), a receptor that is expressed on microglial cells. A safety and tolerability study is looking to see if there are any unanticipated, possibly harmful, effects of the use of the radiotracer in humans. However, ultimately, the investigators would like to know if this drug can be used to make better images of the brain for patients with amyotrophic lateral sclerosis (ALS), which could help doctors better understand the disease and help take care of patients with ALS. This study will use a radiotracer to look for a chemical receptor which ALS patients have more of in the brain. After receiving the radiotracer, participants' brains will be scanned with a positron emission tomography (PET) imaging machine. ;
