Research & Publications

Research Summary

Dr Budimirovic has steadily contributed as a child psychiatrist, and main clinician, to the Fragile X Research Program at the Kennedy Krieger Institute. His research activities have focused on characterizing social behavior determinants of ASD status in Fragile X Syndrome (FXS) (Budimirovic et al., 2006; Kaufmann et al., 2008). The 2006 paper has been cited 53 times to date, as we generated a model that contributed to the field aimed at identification of the FXS-specific Social Avoidance factor structure. The finding was then validated by a multisite effort using a 10-times larger sample (Sansone et al., 2012), which is of much relevance as the key outcome measure for unfolding targeted treatments in FXS and ASD (Berry-Kravis et al., 2012). The aforementioned findings have also served as the foundation for several competitive applications submitted to NIH RO1 and other funding agencies. The research effort has also resulted in an invited critical review (Budimirovic & Kaufmann, 2011), cited 40 times to date in journals with impact factor above 5 such as Molecular Autism and Cell Reports, and poster presentations at national conferences. Most recently, Dr Budimirovic accomplished a fruitful collaboration with the Section on Cellular Signaling head by Dr. Stojiljkovic at NICHD, NIH, on cellular mechanisms underlying prolactin-related effects of two widely prescribed antipsychotics, which resulted in a publication in Nature Sci. Rep (Kucka et al., 2015).

Next, as the PI, Dr. Budimirovic continues to build up a sampling (FMRP blood draws) effort for a March 2013-present IRB NA_00069920 approved study ‘Genotype-Phenotype: High Resolution FMR1 Genetic and Epigenetic Molecular Assessments in Fragile X Patients.’ The study uses the novel PCR method that precisely quantifies the FMR1 alleles aimed at advancing an understanding of autism in fragile X mutations.

It is noteworthy that Dr. Budimirovic remains active on the FXCRC CTC (database-CDC fund renewed in August of 2015), FXCRC FORWARD Data Interest Group Cognition/Behavior/Sleep (database driven, CDC), FORWARD Data Interest Group Psychopharmacology-Behavior (database driven, CDC).

Clinical Trial Keywords

fragile x; autism spectrum disorder; anxiety; developmental disabilities; mood disorders; ADHD; sleep disorders

Clinical Trials

To date, Dr Budimirovic participated in a total of 28 clinical trials not only in the field of pediatric and adult FXS but also in idiopathic ASD, pediatric depression, anxiety, mood and sleep disorders, pediatric and adult ADHD. Currently, Dr. Budimirovic remains the main Sub-Investigator physician at KKI’s CTU, with variable percentage effort for 12 ongoing clinical trials. In addition, several new clinical trials are expected to be approved soon by JHH IRB.
