The PIONEER Initiative: Precision Insights On N-of-1 Ex Vivo Effectiveness Research Based on Individual Tumor Ownership (Precision Oncology)

The PIONEER Initiative stands for Precision Insights On N-of-1 Ex vivo Effectiveness Research. The PIONEER Initiative is designed to provide access to functional precision medicine to any cancer patient with any tumor at any medical facility. Tumor tissue is saved at time of biopsy or surgery in multiple formats, including fresh and cryopreserved as a living biospecimen. SpeciCare assists with access to clinical records in order to provide information back to the patient and the patient's clinical care team. The biospecimen tumor tissue is stored in a bio-storage facility and can be shipped anywhere the patient and the clinical team require for further testing. Additionally, the cryopreservation of the biospecimen allows for decisions about testing to be made at a later date. It also facilitates participation in clinical trials. The ability to return research information from this repository back to the patient is the primary end point of the study. The secondary end point is the subjective assessment by the patient and his or her physician as to the potential benefit that this additional information provides over standard of care. Overall the goal of PIONEER is to enable best in class functional precision testing of a patient's tumor tissue to help guide optimal therapy (to date this type of analysis includes organoid drug screening approaches in addition to traditional genomic profiling).

Ultrasound-based Blood-brain Barrier Opening and Albumin-bound Paclitaxel for Recurrent Glioblastoma

Paclitaxel is among the most active agents against glioblastoma in preclinical models. However, its clinical use has been hampered by the blood-brain barrier (BBB). In this trial we will implant a novel device with 9 ultrasound emitters allowing to temporarily and reversibly open the BBB immediately prior to chemotherapy infusion with albumin-bound paclitaxel. In this phase 1 trial increasing doses of chemotherapy will be delivered as long deemed safe and prior patient had not experienced severe toxicity. Once the the recommended dosing has been established, additional patients will be treated in order to better evaluate the antitumor efficacy of this novel treatment. The device will be implanted at the time of surgical resection of the recurrent tumor. During that procedure a first test dose of the chemotherapy will be administered in the operating room after sonication (procedure of activating ultrasound and opening the BBB) and tissue concentrations in different parts of the resected tumor will be measured. In select patients, the sonication procedure will occur immediately after the test dose of chemotherapy is administered. The objectives of this trial are to establish a safe and effective dose of ABX, to demonstrate that the opening of the BBB increases chemotherapy concentration in the tumor, and to estimate how effective this treatment is in reducing the tumor burden and prolonging life.
