ClinConnect Summary

This clinical trial is studying a medication called neflamapimod to see if it can help people with a type of language disorder called nonfluent variant primary progressive aphasia (nfvPPA). This condition makes it hard for people to speak smoothly and form sentences correctly. The study aims to find out if neflamapimod is safe to use, how the body processes the drug, and whether it has any positive effects on language and communication in people with nfvPPA.

People who might be eligible for this study are adults between 40 and 75 years old who have been diagnosed with nfvPPA based on specific speech and language features. Participants need to have a reliable study partner who can attend visits with them, and both must be comfortable speaking and understanding English. During the study, participants can expect regular visits where their language abilities, safety, and overall health will be monitored. Some medical conditions or recent treatments may prevent someone from joining, so the research team will carefully review each person’s health history. This study is currently recruiting participants, and it offers a chance to contribute to research that may improve treatments for this challenging condition.
