TGen has proven a fertile environment for Dr. Dhruv’s background in bioengineering to gain a translational thrust through development and characterization of patient derived models of cancer for utilization in precision medicine. Malignant tumors when present in the brain present the highest challenge with most dismal prognosis and very limited treatment options. This sets the stage for his major research initiatives: 

1. The most common and most aggressive primary brain tumor, glioblastoma (GB), defies management by surgery, radiation, and conventional chemotherapy. One of the major foci of Dr. Dhruv’s lab is to develop and deploy preclinical models of GB to practice precision medicine.  Dr. Dhruv uses comprehensive molecular characterization (including DNA and RNA Sequencing) combined with targeted therapeutics to discover relationships predictive of in vivo tumor response.  As Assistant Professor in the Brain Tumor Unit (BTU) he oversees the use of 75 patient derived xenograft (PDX) models of GB. Multiple vibrant collaborations with academic and pharmaceutical partners access these models for testing targeted therapeutics and understanding how best to match drug to vulnerable tumor. In addition, these models provide a rich platform for testing novel bioinformatic tools to improve precision medicine algorithms.    

2. Establish clinical partnerships to move novel therapeutics into clinical trials for treatment of GB.  We are currently collaborating with Barrow Neurological Institute (BNI) for a very novel Phase 0 clinical trial to investigate BBB permeability of the Wee1 inhibitor AZD1775. Additionally, we carried out correlative studies using PDX resources developed by BTU to identify molecular markers of response for AZD1775. 

3. Establish clinical partners to access retrospective clinical trial specimens to discover a genomic context of vulnerability for targeted therapeutics and validate the identified signature using PDX resources developed by BTU. We are currently collaborating with Northwestern University and Baylor Scott & White Research Institute to validate the genomic context of vulnerability to Arsenic Trioxide in GB.

4. Among the more encouraging advances in the field of cancer research over the last decade is the emergence of “local control” of cancer using frontline therapies. Such advances, while celebrated, underscore the aggressive regrowth of cancer cells in distant organs, accounting for 95% of all cancer deaths. A diagnosis of central nervous system (CNS) recurrence is not uncommon in patients with breast cancer and an estimated 10% to 30% of all breast cancer patients will eventually develop brain metastases. The diagnosis of breast cancer brain metastases is associated with the shortest survival time compared with other sites of metastatic spread and with progressive neurologic deficits that result in a reduced quality of life. Dr. Dhruv’s lab develops preclinical models of breast tumor metastasis to the brain for use in evidence-based precision medicine.

Dr. Dhruv joined TGen as a post-doctoral fellow in 2009 under the mentoring of Dr. Michael Berens. Dr. Dhruv did his first post-doctoral fellowship at ASU developing a novel drug delivery system for treatment of GB. He obtained his MS and PhD degrees in Bioengineering from Utah State University.
