In our studies, entinostat dramatically improved sensitivity to the rhabdomyosarcoma chemotherapeutics & radiation (see our publications in Genes & Development and Science Signaling). The Phase I study is underway (clinicaltrials.gov NCT02780804) … the race is on to generate the data enabling the Phase II clinical trial. But can we do better? We believe so by study of SMARCA4 and its inhibitors.

The goal of this preclinical study is to validate marizomib as a treatment for medulloblastoma.

Gleevec inhibits the BCR-ABL oncogene in childhood and adult leukemias, but the drug is taken for years because “reserve cells” can lead to relapse if gleevec treatment is stopped too early. This pilot project explores why the gleevec-indifferent reserve cells may exist, based on unexpected preliminary data that leads to a radical new way to think of fusion oncogenes.

The mission of the ASPS/Xp11 RCC/PEComa/EHE Cancers Consortium is to catapult the discovery of treatment options for these cancers that share common molecular features (e.g., TFE3 gene fusions). Our goal is to advance novel drug and drug combinations to clinical trial for these cancers.

Embryonal tumors with abundant neuropil and true rosettes (ETANTR) is a rare category of brain tumors of children that generally occurs in the cerebrum (but not exclusively) and has a median survival of only 9-13 months. Due to the severe nature of this tumor and the scarcity of preclinical resources necessary to make drug screens possible, our consortium will start by developing cell lines and mouse models and then create shareable central resource(biorepository) for cell lines and mouse models.

Approximately 100 patients are diagnosed with hepatoblastoma each year in the United States, and for the 20% of patients with unresectable or metastatic hepatoblastoma exist limited options. We propose preclinical validation studies of the drug volasertib, which targets the Polo-like kinase 1 (PLK1) oncogene in hepatoblastoma.

Alveolar rhabdomyosarcoma is a cancer of the soft tissues. Local control for rhabdomyosarcoma is an important clinical challenge, and recurrence at the tumor resection bed can be a gateway to progression and metastasis. Our project seeks to put the types of cutting edge, non-chemotherapy medicines used by internists into the hands of the surgeon for the purpose of preventing local recurrence at the earliest possible moment.

Osteosarcoma is a difficult cancer to have, a difficult cancer to treat, and a difficult cancer to understand. Osteosarcoma afflicts children, adults, pet dogs and even mice – a perfect storm to understand what drives this disease by looking at what is in common in all of these patients. Despite the need for better treatments and the despite efforts of the brightest and most innovative clinical trialists over the last 25 years, we remain unable to understand the key therapeutic targets of this disease

We need to move from a fragmented collection of osteosarcoma knowledge to a centralized one that is shared freely – and co-developed by patients and families.

We propose a pilot study to (1) design a computational model of patient-specific flow conditions in the vicinity of a brain tumor leptomeningeal metastasis, and (2) to experimentally test whether drug exposures under those flow conditions would be effective against medulloblastoma tumor cells that represent the biology of the patient’s tumor.

Can we define a new standard of care for every subgroup of children battling aRMS? This project is important because many children, teens and young adults with alveolar rhabdomyosarcoma need new treatment options. When metastatic, the five-year survival rate is only 8%. We want aRMS to be universally survivable

Generating data as efficiently and accurately as possible, we plan to have drug – genetic matches for each type of embryonal rhabdomyosarcoma … and to publish this data, but also to share it in real time with pediatric oncologists of eRMS patients who may have scientific interest.

This multi-disciplinary approach to accelerating discovery of therapies for childhood cancer is made possible by a joint effort of our scientific director Dr. Keller and our Board member, Sunit Rikhi, former VP of the Intel custom foundry. Together, our teams of biologists and engineers will maximize automation and the design of new devices and biomaterials that address challenges in the treatment of cancer as well as prevention of recurrence, ultimately improving outcomes for children with cancer.

An outstanding field of basic scientists and clinical investigators have explored the chemical space (druggable space) for osteosarcoma and have pioneered an efficient system of rapidly-completed phase II studies in the Children’s Oncology Group. Drugs have included RANKL inhibitors, anti-disialoganglioside antibodies, irreversible tubulin inhibitors, and anti-glycoprotein NMB conjugates – among others.

EPS does not yet have a long history of international clinical data collection, with centralized imaging, histology slides or specimen collection (e.g., for future DNA and RNA studies). The purpose of this proposal is to empower a centralized resource of all available EPS data and resources so that Big Data (machine learning) can answer key questions around EPS care. Goals include Patient-oriented Registry & Biobank, Proteomics, Cutting-edge Database & Sequence Analysis Pipelines, Synchronization and Sharing, Outreach and Portability and Publication.
