Professional Bio: 

Dr. Abraham Jacob is an Otologist/Neurotologist who specializes in the treatment and rehabilitation of complex ear and lateral skull base diseases.   He is double board-certified in Otolaryngology as well as Otology, Neurotology, and Cranial Base Surgery.  Dr. Jacob obtained his medical degree at the University of Michigan Medical School, completed internship and Otolaryngology-Head and Neck residency at Washington University School of Medicine in St. Louis, and was a fellow in Otology, Neurotology, and Cranial Base Surgery at The Ohio State University.  He is an Associate Professor with Tenure at UA, Vice Chair of Otolaryngology, and the Director of the UA Ear Institute – the most comprehensive ear program in the Southwest. 

Dr. Jacob is an Associate Professor of Otolaryngology.  He has a strong track record in drug development that includes designing and performing all the necessary in vitro and animal studies required for the small molecule HDAC inhibitor, AR42, to receive Orphan Drug status from the FDA and European Agency in 2012.  This drug is now registered on clinicaltrials.gov for a multicenter human trial in neurofibromatosis type 2 patients. His lab has also recently developed, validated, and published a novel high throughput zebrafish behavioral assay that can be used as a platform for drug discovery targeting hearing loss.  He has key collaborations in the field of drug development, including collaborations with Cochlear Corporation and Sanofi-Aventis.  Through these collaborations, he brings his experience in clinical and translational research and drug development into alignment with the knowledge and insight of some of the world’s best laboratories, where they are working to deliver pharmacological tools for hypothesis development, validation and, therapeutics development.

In addition to running a fully functioning molecular biology laboratory focused on preclinical drug development for skull base schwannomas/meningiomas as well as sensorineural hearing loss, Dr. Jacob has partnered with several implantable hearing device manufacturers for device related clinical trials, including Cochlear Corporation (Expanded Indications Study), and Envoy Medical (Post-Market 0205 Study).  He also serves as PI on a third study, Advanced Bionics (Cochlear Implants and Cognitive Function Study), focusing on how hearing loss influences the health and functioning of older adults, and the role that cochlear implants might have in ameliorating cognitive decline resulting from auditory deprivation.

Finally, as the only university based, academic Neurotologist in Arizona, Dr. Jacob's program at UA Ear Institute is optimally positioned for the development and implementation of research and clinical trials for skull base schwannomas/meningiomas as well as studies on hearing loss.

Summary of Research Activity: 

Dr. Jacob's research interests include the pathobiology of NF2-associated tumors such as vestibular schwannomas and meningiomas and in small molecule target identification and development for these diseases.  His experience includes executing in vitro and in vivo studies for the small molecule HDAC inhibitor, AR42, which received Orphan Drug status from the FDA and European Agency in 2012.  Dr. Jacob’s research  is also focused on the prevention, detection, treatment, and rehabilitation of chemotherapy-induced hearing loss (ototoxicity).
