Molecular Profiling in Guiding Individualized Treatment Plan in Adults With Recurrent/Progressive Glioblastoma

Completed

• Conditions: Adult Glioblastoma
• Interventions: Other: specialized tumor board recommendation

• Registration Number: NCT02060890
• Lead Sponsor: University of California, San Francisco

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.

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.

Exclusion Criteria

• Uncontrolled concurrent illness including psychiatric illness, or situations that would limit compliance with the study requirements or the ability to willingly give written informed consent

Eligibility for treatment using the specialized Tumor Board recommendations

• Patients must have fully recovered from any toxicity associated with surgery
• Must begin treatment no longer than 35 calendar days from surgery
• Must have KPS at least 60
• Must have Absolute Neutrophil Count (ANC) at least 1500/mm3, platelets at least 125,000/mm2, Hg at least 8 gm/dl

• Must have baseline MRI within 14 days prior to starting cycle 1, day 1 of treatment (+/- 3 days)
• Additional laboratory guidelines will be based upon therapies suggested by the specialized Tumor Board based upon anticipated, known toxicities of those agents and must be within at least 1.5 x upper normal limits of institutional normal limits
• Patient must agree to follow the recommended treatment regimen, including clinic visits, laboratory, imaging, and toxicity assessments

Arm && Interventions

Group	Intervention	Description
Group A	specialized tumor board recommendation	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.

Primary Outcome Measures

Name	Time	Method
Number of Participants Who Received Treatment Recommendations Within 35 Days of Surgery	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

Name	Time	Method
Number of Patients Who Chose to Pursue Treatment	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
