Nonfluent Variant Primary Progressive Aphasia (nfvPPA)

The goal of this exploratory study is to evaluate the effect of neflamapimod in participants with nonfluent variant primary progressive aphasia (nfvPPA). We aim to evaluate the safety, pharmacokinetics and clinical effects of neflamapimod of participants with nfvPPA.

The goal of this clinical trial is to learn whether a personalized, multi-component, virtual speech language treatment program can improve communication and quality of life for adults with primary progressive aphasia (PPA) and their primary communication partners. The study will enroll participants who speak English and/or Spanish. The main questions the study aims to answer are: * Is the telerehabilitation program feasible and acceptable for people with PPA and their study partners? * Do participants with PPA and study partners find treatment beneficial? * What patterns of treatment response are seen in participants? * Which outcome measures are most useful for evaluating changes in communication and quality of life? Researchers will compare participants who receive intervention immediately to participants assigned to a waitlist control group (who will receive treatment after a delay) to see whether participation in the treatment program is associated with improvements in communication and quality of life. Participants will: * Take part in speech language therapy sessions delivered by video visit that combine restorative, compensatory, and partner-focused communication strategies. Treatment may take place after a waiting period. * Receive education and communication training together with their partner. * Complete speech, language, and cognitive assessments. * Complete questionnaires about communication abilities, daily functioning, and quality of life.
