D-serine AudRem: R33 Phase
D-serine Augmentation of Neuroplasticity-based Auditory Learning in Schizophrenia: R33 Phase
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. nov. 2.
Rövid összefoglaló (regiszter, angolul)
Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the D-serine treatment over 16 weeks of a program designed to measure auditory plasticity.

Ki nem vehet részt
Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.
Korábbi kezelés
- Participation in study of investigational medication/device within 4 weeks
- Subjects with suicidal ideation with intent or plan (indicated by affirmative answers to items 4 or 5 of the Suicidal Ideation section of the baseline C-SSRS) in the 6 months prior to screening or subjects who represent a significant risk of suicide in the opinion of the investigator
Más betegség
- Presence of positive history of unstable significant medical or neurological illness
Laborértékek
- Pregnant women or women of child-bearing potential, who are either not surgically-sterile or for outpatients, using appropriate methods of birth control. Women of child-bearing potential must have a negative serum beta-hCG pregnancy test at screening.
Egyéb
- Substance abuse (excluding nicotine) within last 60 days
- ECG abnormality that is clinically significant in the context of study participation in the opinion of the study cardiologist
- Current clozapine use. Clozapine is excluded for two reasons: to avoid the potential confound of treatment resistant patients and because of clozapine's intrinsic NMDA agonist
- Positive toxicology screen for any substances of abuse
