Abstract BACKGROUND Comprehensive next generation sequencing (NGS) is available through many academic institutions and commercial entities, and is incorporated in practice guidelines for glioblastoma (GBM). We retrospective evaluated the practice patterns and utility of incorporating NGS data into routine care of GBM patients at a clinical trials-focused academic center. METHODS We identified 1,011 consecutive adult patients with histologically confirmed GBM with OncoPanel testing, a targeted exome NGS platform of 447 cancer-associated genes at Dana Farber Cancer Institute (DFCI), from 2013-2019. We selected and retrospectively reviewed clinical records of all IDH-wildtype GBM patients treated at DFCI. RESULTS We identified 557 GBM IDH-wildtype patients, of which 227 were male (40.7%). OncoPanel testing revealed 833 single nucleotide variants and indels in 44 therapeutically relevant genes (Tier 1 or 2 mutations) including PIK3CA (n=51), BRAF (n=9), FGFR1 (n=8), MSH2 (n=4), MSH6 (n=2) and MLH1 (n=1). Copy number analysis revealed 509 alterations in 18 therapeutically relevant genes including EGFR amplification (n= 186), PDGFRA amplification (N=39) and CDKN2A/2B homozygous loss (N=223). Median overall survival was 17.5 months for the whole cohort. Seventy-four therapeutic clinical trials accrued 144 patients in the upfront setting (25.9%) and 203 patients (36.4%) at recurrence. Altogether, NGS data for 107 patients (19.2%) were utilized for clinical trial enrollment or targeted therapy indications. High mutational burden (>17mutations/Mb) was identified in 11/464 samples (2.4%); of whom 3/11 received immune checkpoint blockade. Four patients received compassionate use therapy targeting EGFRvIII (rindopepimut, n=2), CKD4/6 (abemaciclib, n=1) and BRAFV600E (dabrafenib/trametinib, n=1). CONCLUSION While NGS has greatly improved diagnosis and molecular classification, we highlight that NGS remains underutilized in selecting therapy in GBM, even in a setting where clinical trials and off-label therapies are relatively accessible. Continued efforts to develop better targeted therapies and efficient clinical trial design are required to maximize the potential benefits of genomically-stratified data.

Abstract BACKGROUND Personalized anti-tumoral therapies may currently be proposed on the basis of immuno-histochemistry, but also next-generation sequencing and comparative genomic hybridization. ProfiLER trial explored the feasibility, efficacy and the impact of molecular profiling for patients with solid or hematological advanced cancers including brain tumors. MATERIAL AND METHODS Patients with primary brain tumors, pre-treated with at least one line of anti-cancer treatment, could be included in this multicentric prospective trial. A molecular profile (next-generation sequencing and comparative genomic hydridization) was established on fresh or archived sample. Weekly molecular tumor board analysed results to propose as far as possible a molecular targeted therapy. RESULTS between February 2013 and December 2015, 141 patients with primary brain tumor were enrolled. One hundred five samples were further analyzed as 30 samples were excluded, and 6 are on-going. The rate of screen failure was 16/33 for stereotactic biopsy (49%) versus 11/104 (11%) for removal. The main representative histologic type of tumors were glioblastoma (n=46, 43,8%), low grade glioma (n=26, 24,8%), high grade glioma (n=12, 11,4%) and atypical and anaplastic meningioma (n=8, 7,6%). Median delay between the diagnostic of the primitive tumor and the inclusion in ProfiLER study was 2.7 years (0.2 - 29 years). Median delay between the consent and the results of the multidisciplinary meeting was 2.8 months (1–7.1 months). Forty-three patients (41%) presented at least one “druggable molecular alteration”. The most frequently altered genes were CDKN2A (n=18, 29%), EGFR (n=12, 20%), PDGFRa (n=8, 13%), PTEN (n=8, 13%), CDK4 (n=7, 11%), KIT (n=6, 10%), PIK3CA (n=5, 8%), MDM2 (n=3, 5%). Sixteen patients could not have a proposition of specific treatment due to death before MBT (n=5, 31.3%), lack of available clinical trials (n=9, 56%), or ambiguous results (n=2, 12.5%). Among the 27 patients (26%) for whom a specific therapy has been proposed, only six patients ultimately received a medical targeted therapy (everolimus n=3, erlotinib n=1, ruloxitinib n=1, sorafenib n=1). Four patients discontinued the treatment for toxicity, the 2 others for clinical progression. CONCLUSION routine high-throughput sequencing is feasible for brain tumors but delays should be reduced to be able to propose targeted therapies to patients fit enough to benefit from experimental treatment. Macroscopic surgery is the best way to obtain workable samples. Specific panel genes for neurologic tumors should be developed, as well as change of practices concerning exclusion criteria in clinical trials.

Purpose: Successful clinical trial accrual targeting uncommon genomic alterations will require broad national participation from both National Cancer Institute (NCI)–designated comprehensive cancer centers and community cancer programs. This report describes the initial experience with clinical trial accrual after next-generation sequencing (NGS) from three affiliated non–NCI-designated cancer programs. Materials and Methods: Clinical trial participation was reviewed after enrollment of the first 200 patients undergoing comprehensive genomic profiling by NGS as part of an institutional intuitional review board–approved protocol at three affiliated hospitals in Rhode Island and was compared with published experience from NCI-designated cancer centers. Results: Patient characteristics included a median age of 64 years, a median of two lines of prior therapy, and a predominance of GI carcinomas (58%). One hundred sixty-four of 200 patients (82%) had adequate tumor for NGS, 95% had genomic alterations identified, and 100% had variants of unknown significance. Fifteen of 164 patients (9.2%) enrolled in genotype-directed clinical trials, and three patients (1.8%) received commercially available targeted agents off clinical trials. The reasons for nonreceipt of NGS-directed therapy were no locally available matching trial (48.6%), ineligibility (33.6%) because of comorbidities or interim clinical deterioration, physician's choice of a different therapy (6.8%), or stable disease (11%). Conclusion: This experience demonstrates that a program enrolling patients in specific targeted agent clinical trials after NGS can be implemented successfully outside of the NCI-designated cancer program network, with comparable accrual rates. This is important because targetable genes have rare mutation rates and clinical trial accrual after NGS is low.

584 Background: Tumor genomic profiling has become critical in the identification of targeted therapeutic options for patients (pts) with advanced malignancies. Mutational frequencies and their therapeutic importance vary among tumor types. This analysis was undertaken to characterize the landscape of genomic alterations in gastrointestinal (GI) malignancies found in a large academic institutional practice, and to determine the frequency of alteration-specific targeted therapy selection based on genomic profiling. Methods: Adult pts with GI malignancies presenting to the Ohio State University Comprehensive Cancer Center oncology clinics were offered next generation sequencing through FoundationOne testing as part of routine clinical care. Institutional review board approval was obtained to retrospectively analyze results from FoundationOne testing performed between 2012 and 2015. Results: 265 pts with GI malignancies underwent successful genomic profiling. 1205 genomic alterations were found, with an average of 4.5 per tumor (range 0-20); 365 (30%) of these were potentially actionable and most often found in colorectal or gastroesophageal tumors. 14 pts (5.3%) had actionable alterations in MET, CDKN2A/B, FGFR2, KRAS, BRAF, or NF2 that led to enrollment in genotype-directed clinical trials or off label use of targeted therapies beyond standard of care. Pt performance status at the time of genomic alteration identification was a significant factor in precluding genotype-directed therapy. One variant of unknown significance involving FGFR2 identified at initial testing subsequently became actionable and led to pt enrollment on a clinical trial. One pt with rectal cancer was found to have a KRAS wild-type and BRAF mutant primary but KRAS mutant and BRAF wild-type liver metastasis. Conclusions: Genomic profiling of GI malignancies through next generation sequencing is feasible and can lead to genotype-directed therapy selection; however, it should be considered early in the pt’s course to optimize use of targeted therapies through clinical trials. Consideration should be given to serial tumor testing to identify emerging genomic alterations for optimal therapy selection.

3073 Background: Widespread integration of systematized next generation sequencing (NGS)-based precision oncology is hindered by numerous barriers. Hence, we developed the Strata trial (NCT03061305), a screening protocol to determine the impact of scaled precision oncology. Methods: We implemented no-cost NGS on formalin fixed paraffin embedded (FFPE) clinical samples for all patients with advanced tumors, a common portfolio of partnered therapeutic clinical trials, and robust infrastructure development across the Strata Precision Oncology Network. Results: Across the network of 17 centers, specimens from 8673/9222 (94%) patients were successfully tested in the Strata CLIA/CAP/NCI-MATCH accredited laboratory using comprehensive amplicon-based DNA and RNA NGS. Patients were tested with one of three StrataNGS test versions; the most recent panel assesses all classes of actionable alterations (mutations, copy number alterations, gene fusions, microsatellite instability, tumor mutation burden and PD-L1 expression). Median surface area of received FFPE tumor samples was 25mm2 (interquartile range 9-95mm2), and the median turnaround time from sample receipt to report was 6 business days. 2577 (27.9%) patients had highly actionable alterations, defined as alterations associated with within-cancer type FDA approved or NCCN guideline recommended therapies (1072 patients), NCI-MATCH trial arms (1467 patients), Strata-partnered therapeutic trials (327 patients), or specific alteration-matched FDA approved therapies in patients with cancers of unknown primary (71 patients). Of the 1467 patients matched to an NCI-MATCH trial arm, 15 enrolled. Of the 327 patients matched to one of nine Strata-partnered clinical trials, 77 (24%) were screen failures, while 250 (76%) have either enrolled or are being actively followed for enrollment upon progression. Conclusions: Through streamlined consent methods, electronic medical record queries, and high throughput laboratory testing at no cost to patients, we demonstrate that scaled precision oncology is feasible across a diverse network of healthcare systems when paired with access to relevant clinical trials. Clinical trial information: NCT03061305.
