Study Description

Brief Summary:

This current study will use a new treatment approach based on each patient's tumor genomic profiling consisting of whole genome sequencing, exome analysis, and RNA sequencing as well as predictive modeling. This new treatment strategy has shown promising results in adult patients with other solid tumors.

Condition or disease	Intervention/treatment
Adult Glioblastoma	Other: specialized tumor board recommendation

Detailed Description:

Patients with recurrent glioblastoma who are candidates for surgery for their clinical management will have tumor tissue taken at the time of surgery. Tissue samples will be obtained from the contrasting edge as well as infiltrating margins. Circulating tumor DNA will also be taken from blood samples before, and after surgery and every 2 months. Genomic profiling of the tumor tissue will be performed and a Molecular Tumor Board will review the profiling within 28 to 35 days of surgery. If specific potential targets are amenable to treatment, a treatment recommendation will be made. Up to 4 drugs could be suggested to the treating physician. The patient and the treating physician may or may not choose to use the recommendation. Any drug from the US Pharmacopeia may be chosen. If the treatment as suggested is given, patients will be followed for toxicity and efficacy, including progression and survival. If the treatment is not given, patients will be followed for progression and survival.

Groups and Cohorts

Group/Cohort

Intervention/treatment

Group A; Patients will undergo collection of tumor at the time of tumor resection and after confirmation of tumor progression and will have blood samples drawn pre-surgery and during standard of care follow-up visits. Patients will then be provided with a specialized tumor board recommendations for personalized treatment options for up to 4 medications based on the specimen analysis results within 35 days of surgery. Patients may then elect to initiate recommended therapy within 42 days of surgery.

Other: specialized tumor board recommendation; feasibility of a specialized tumor board to come up with treatment recommendations no later than 35 days from surgery.; Other Name: standard of care therapy

Outcome Measures

Primary Outcome Measures :

1. Number of Participants Who Received Treatment Recommendations Within 35 Days of Surgery [ Time Frame: 35 days from surgery to making genomic informed treatment recommendation ]
   To demonstrate feasibility, we would want the treatment recommendation to be fully complete within 35 calendar days in at least 85% of patients for which sufficient RNA and DNA is available.

Secondary Outcome Measures :

1. Number of Patients Who Chose to Pursue Treatment [ Time Frame: Within 35 days from surgery to making genomic informed treatment recommendation ]
   Number of patients who chose to pursue treatment based on these genomics-informed treatment recommendations

Other Outcome Measures:

1. Successful Generation of Patient-derived Xenograft (PDX) Genomic Models [ Time Frame: Within 12 months after tissue collection ]
   Number of patient-derived xenograft (PDX) models successfully derived from patient tumor samples.
2. Number of Participants Reaching 12 Months Progression Free Survival [ Time Frame: 12 month progression free survival ]
   Treatment efficacy derived from specialized Tumor Board suggestion, defined by 12 month progression free survival.

Biospecimen Retention:   Samples With DNA

Surgery is done and a "core" specimen (from the enhancing component of tumor) and one or more tissue biopsies of the surrounding "rim" are obtained and processed for shipment to TGen for NGS and transcriptome profiling.

Blood is obtained prior to and 24 hours following surgery for assessment of any circulating tumor DNA in blood.

Blood for circulating tumor DNA is collected every 28 days (+/- 7 days).

Whole blood samples will be immediately sent to Ashion for extraction of DNA. Isolated DNA will be quantitated by spectrophotometry, and the distribution of molecular weights in the preparations will be visualized by gel electrophoresis. Blood derived DNA samples will be aliquoted and kept at Ashion at -20 degrees Celsius until use in molecular studies

Criteria

Inclusion Criteria:

• Have a life expectancy of at least 3 months
• Patients must have a diagnosis of histologically confirmed Glioblastoma that is felt on imaging to be progressive despite standard of care treatment
• at least 18 years of age
• Patient is a good medical candidate for a standard of care surgical procedure
• Patients may enroll independent of number of prior therapies, but must have received prior radiation therapy
• Patients must have a performance status (KPS) of at least 60.

Exclusion Criteria:
