    Abstract: 6508 Background: Physicians in the community have a broad range of experience using genomics data to inform treatment decisions. They typically have a heavier patient load than found in academic centers and treat a variety of tumor types. Genomic data has been reportedly used less than anticipated, even when results were actionable. Monthly didactic molecular tumor boards have been implemented in a number of cancer centers to try to fill gaps in knowledge. Methods: A weekly virtual consultative molecular tumor board (MTB) was implemented (Mar 2016) at an academic hybrid, multi-site community-based cancer institute to provide rapid molecularly-driven treatment guidance to physicians, augment genomics education, provide supporting documents for off-label use and clinical trials. A baseline survey was performed prior to first MTB. MTB assessments were summarized and provided to treating physician. Data was abstracted from the electronic medical records and clinical trials management system. Descriptive statistics were utilized to summarize utilization of MTB and treatment recommendations. Results: Genomics testing with a large panel (~600 genes) was requested for 809 patients (Jun 2015-Feb 2017). The MTB received 81 requests for review from 32 physicians from 14 locations. Most commonly reviewed disease sites were lung, ovary, pancreatic, colon, breast and head and neck cancers; 37% of reviews requested were for rare tumors. Median time to review request was 15 days from receipt of results. MTB recommendations were followed in 70% of cases, 16% continued current/other therapy, 11% declined rapidly (hospice/died), and 3% of patients decided against recommendations. Forty-four (44) percent were screened for recommended clinical trials; 26% went on study. Conclusions: Implementation of a weekly virtual consultative MTB facilitates molecularly-driven treatment decisions in community setting, especially in rare tumor types and enhances clinical trial accruals.

    Abstract: Clinical trials of novel and targeted agents increasingly require biomarkers for eligibility. Precision oncology continues to evolve, but challenges hamper broad use of molecular profiling (MP) that could increase the number of patients benefiting from targeted therapy. We implemented an integrated clinical genomics program (CGP), including a virtual Molecular Tumor Board (MTB), and examined its impact on MP use and impact on clinical trial accrual in a multisite regional-based cancer system with an emphasis on effects for isolated clinicians. METHODS We assessed MP and MTB use from 2010 to 2020 by practice location, physician experience, and patient characteristics. Use of MTB-recommended treatments was assessed. Clinical trial enrollment was evaluated for patients with MP versus MP and MTB review. RESULTS After CGP implementation, the number of physicians using MP and the number of MP tests increased ≥ 10-fold. The proportion of Hispanic patients with MP was the same as that in the system (both 2%) with marginal differences observed in the proportion of African Americans tested compared with the system population (16% v 19%). Physicians followed MTB treatment recommendations in 74% of cases. Rapid clinical decline was the most common reason why physicians did not follow MTB recommendations. Clinical trial accrual was 15% (669 of 4,459) for patients with MP alone and 28% (94 of 334) with both MP and MTB review. Clinical trial availability and patient out-of-pocket costs affected MP use. CONCLUSION Integrating CGP into clinical workflow with decision support tools, trial matching, and management of patient costs led to increased use of MP by physicians with all levels of experience, enhanced clinical trial accrual, and has the potential to reduce disparities in MP.

    Abstract: e18000 Background: Genomic testing requires greater quality than routine clinical diagnostic tests. As genomic testing proliferates and becomes more widespread, adjustments in processes may be needed by community-based pathology, radiology, and surgery groups. Both tissue quality and quantity parameters are essential for successful completion of next-generation sequencing (NGS) panels. Methods: A NGS genomic platform ( 〉 600 genes) was implemented in a hybrid academic community-based cancer institute, with success/failure rates recorded.. Data were collected from the electronic medical records and biorepository data system. Descriptive statistics assessed success or failure rates by tissue quality or quantity with subgroup analyses by disease sites (primary/metastases), collection procedure, and specimen age. Results: From 6/2015-2/2017, 809 NGS tests yielded 143 (17%) failures [specimen quality (34%) and specimen quantity (66%)]. Of the failed tests, specimens were collected from 26 primary disease sites [lung (21%)] and 18 metastatic sites [liver (29%), lymph node (19%), and lung, omentum, brain, and peritoneal specimens (all 〈 10%)]. Of the failed tests, all bronchoscopy, EBUS, and peritoneal fluid specimens and the majority of FNAs (78%) were due to insufficient tissue quantity, whereas surgical resection or excision had more issues with quality of the specimen (60%). Of note, surgical specimens ranged from 2005-2016; NGS quality initiatives were implemented system-wide in 2015, leading to substantially fewer failed tests. Cores biopsies had fewer quantity (24%) or quality (18%) issues. The number of tests failing due to insufficient quantity also declined due to education and communication processes implemented. Conclusions: The majority of NGS tests provided valuable information. Implementation of systematic tissue collection (core biopsies) and processing, for primary lung and lung and liver metastases using core biopsies consistently provided the fewest failures and implementing NGS-specific processes improved NGS success rates.

    Abstract: e16501 Background: High-dose interleukin-2 (HD IL-2) was the first approved immune-oncology (IO) agent based on proven clinical efficacy in renal cell carcinoma (RCC) and metastatic melanoma, but its use was limited due to significant toxicities. Multiple next-generation IL-2 agents designed to retain efficacy while improving tolerability are in development. Yet, understanding of genomic markers that define optimized target pharmacology is incomplete. Newer evaluation techniques not available at the time of previous HD IL-2 experience may allow for identification of pertinent genomic markers. In this retrospective study, we report for the first time, RNA sequencing (RNAseq) of peripheral blood mononuclear cell (PBMC) samples from metastatic (mRCC) patients before, during and after HD IL-2 treatment. Detailed immunogenomic responses to HD IL-2 treatment with insight into traditional flow cytometry (FC) are presented. Methods: PBMC samples were collected for n = 23 HD IL-2 treated mRCC patients between 2009 and 2015 on Day 1, 3 and 5. Patient samples underwent prior FC analysis described elsewhere (Foureau et al, 2014; Cancer Immunol. Immunother. 63(12)). RNAseq was performed using NovaSeq6000 (Illumina) paired end sequencing on bulk PBMC samples from immediately before (Day 1), during (Day 3) and post-treatment (Day 5) Cycle 1 and/or Cycle 2 of the first course of HD IL-2. Individual genes and signatures for immune and proliferation differences were analyzed. Results: RNAseq analysis of PBMC samples demonstrated that CD8+ T cells transiently decreased in the blood during treatment but recovered to baseline on Day 5, and CD4 Treg cells increased on Day 3 and Day 5, which confirmed prior FC findings. TCR clonality was unchanged which indicates that T cell recovery and expansion is widespread and not driven by a specific subset of T cells. Additional notable insights included increased monocytes at Day 3, with the opposite for NK and B cells (Day 3 decrease and Day 5 expansion). Using a novel GeneCentric proliferation signature, increased expression was noted on Day 3 and Day 5 vs. Day 1, reflecting pronounced IL-2 induced proliferation. Conclusions: Immunogenomics provided further detail regarding IL-2 activity in addition to recapitulating several parameters from FC. Expression analysis of minimally invasive PBMC samples demonstrates the importance of this novel genomic approach to understand the pharmacology of IL-2 and related derivatives.

    Abstract: 11519 Background: Doxorubicin has been the traditional standard therapy for treatment of advanced soft tissue sarcoma (STS). The addition of cytotoxic agents leads to increased toxicity with minimal improvement in efficacy. Pembrolizumab monotherapy has demonstrated activity and tolerability in previous study of advanced STS. This study combined pembrolizumab with doxorubicin to determine safety and efficacy in the frontline setting. Methods: This single-center, single-arm, phase 2 trial enrolled subjects with unresectable or metastatic STS and no prior anthracycline therapy. Subjects were treated with pembrolizumab 200 mg IV and doxorubicin 60 mg/m2 (75 mg/m2 dose escalation per investigator discretion) IV every 3 weeks. The primary endpoint of safety, based on Bayesian stopping rules, evaluated if the severe or life-threatening treatment emergent adverse event (TEAE) rate exceeded 0.55. Secondary endpoints included overall survival (OS), objective response rate (ORR), and progression free survival (PFS). Efficacy and safety were based on RECIST 1.1 and CTCAE v 4.0, respectively. Kaplan-Meier methods evaluated time to event outcomes. Results: From 4/2017 to 12/2019, 30 subjects (53% female, median age 61.5 years, 10 patients 〉 70 years (33%)) were enrolled in the study with 6 (20%) patients still on treatment and 27 evaluable for response. The most common histologic subtypes were leiomyosarcoma (33%) and liposarcoma (23%), and a majority of patients demonstrated high grade disease (60%). Current analysis shows a median follow-up of 9.9 months. One subject experienced a stopping rule event (grade 3 autoimmune disorder). ORR was 33% (95% CI 17-54%), with documented disease control in 78% (95% CI 57.7-91.4%) of patients. Eight (30%) patients achieved a partial response, one (4%) patient achieved a complete response and 12 (44%) patients had stable disease. Preliminary results demonstrate median PFS of 6.9 months (PFS-6 mo: 52%) and median OS of 15 months (OS-6 mo: 81%) compared to historical PFS-6mo of 4.6 months and OS of 12.8 months with doxorubicin alone. 1 Most common grade 3+ TEAEs included neutropenia (11 [37%]), febrile neutropenia (6 [20%] ), anemia (5 [17%]), and nausea (4 [13%] ). Molecular and biomarker analysis is currently in progress. Conclusions: The combination of pembrolizumab with doxorubicin has manageable toxicity and preliminary promising activity in the treatment of anthracycline-naive advanced soft tissue sarcomas.

    Abstract: Agents can enter clinical development for cancer prevention either initially or after previous development for a different indication, such as arthritis, with both approaches consuming many years of development before an agent is fully evaluated for cancer prevention. We propose the following, third approach: reverse migration, that is, importing agents, targets, and study designs to personalize interventions and concepts developed in advanced cancer to the setting of cancer prevention. Importing these “ready-made” features from therapy will allow reverse migration to streamline preventive agent development. We recently reported the Biomarker-integrated Approaches of Targeted Therapy for Lung Cancer Elimination (BATTLE) trial of personalized lung cancer therapy and now propose the reverse migration development of personalized lung cancer prevention based on the BATTLE model.

    Abstract: Patients with unresectable dedifferentiated liposarcoma (DDLPS) have poor overall outcomes. Few genomic alterations have been identified with limited therapeutic options. Experimental Design Patients treated at Levine Cancer Institute with DDLPS were identified. Next generation sequencing (NGS), immunohistochemistry (IHC), and fluorescence in situ hybridization (FISH) testing were performed on tumor tissue collected at diagnosis or recurrence/progression. Confirmation of genomic alterations was performed by orthologous methods and correlated with clinical outcomes. Univariate Cox regression was used to identify genomic alterations associated with clinical outcomes. Results Thirty‐eight DDLPS patients with adequate tissue for genomic profiling and clinical data were identified. Patient characteristics included: median age at diagnosis (66 years), race (84.2% Caucasian), and median follow‐up time for the entire cohort was 12.1 years with a range from approximately 3.5 months to 14.1 years. Genes involved in cell cycle regulation, including MDM2 (74%) CDK4 (65%), and CDKN2A (23%), were amplified along with WNT/Notch pathway markers: HMGA2, LGR5, MCL1, and CALR (19%–29%). While common gene mutations were identified, PDE4DIP and FOXO3 were also mutated in 47% and 34% of patients, respectively, neither of which have been previously reported. FOXO3 was associated with improved overall survival (OS) (HR 0.37; p  = 0.043) along with MAML2 (HR 0.30; p  = 0.040). Mutations that portended worse prognosis included RECQL4 (disease‐specific survival HR 4.67; p  = 0.007), MN1 (OS HR = 3.38; p  = 0.013), NOTCH1 (OS HR 2.28, p  = 0.086), and CNTRL (OS HR 2.42; p  = 0.090). Conclusions This is one of the largest retrospective reports analyzing genomic aberrations in relation to clinical outcomes for patients with DDLPS. Our results suggest therapies targeting abnormalities should be explored and confirmation of prognostic markers is needed. Dedifferentiated liposarcoma is one of the most common subtypes of soft tissue sarcoma yet little is known of its molecular aberrations and possible impact on outcomes. The work presented here is an evaluation of genetic abnormalities among a population of patients with dedifferentiated liposarcoma and how they corresponded with survival and risk of metastases. There were notable gene mutations and amplifications commonly found, some of which had interesting prognostic implications.

    Abstract: Doxorubicin is standard therapy for advanced soft-tissue sarcoma (STS) with minimal improvement in efficacy and increased toxicity with addition of other cytotoxic agents. Pembrolizumab monotherapy has demonstrated modest activity and tolerability in previous advanced STS studies. This study combined pembrolizumab with doxorubicin to assess safety and efficacy in frontline and relapsed settings of advanced STS. Patients and Methods: This single-center, single-arm, phase II trial enrolled patients with unresectable or metastatic STS with no prior anthracycline therapy. Patients received pembrolizumab 200 mg i.v. and doxorubicin (60 mg/m2 cycle 1 with subsequent escalation to 75 mg/m2 as tolerated). The primary endpoint was safety. Secondary endpoints included overall survival (OS), objective response rate (ORR), and progression-free survival (PFS) based on RECIST v1.1 guidelines. Results: Thirty patients were enrolled (53.3% female; median age 61.5 years; 87% previously untreated) with 4 (13.3%) patients continuing treatment. The study met its primary safety endpoint by prespecified Bayesian stopping rules. The majority of grade 3+ treatment-emergent adverse events were hematologic (36.7% 3+ neutropenia). ORR was 36.7% [95% confidence interval (CI), 19.9–56.1%], with documented disease control in 80.0% (95% CI, 61.4–92.3%) of patients. Ten (33.3%) patients achieved partial response, 1 (3.3%) patient achieved complete response, and 13 (43.3%) patients had stable disease. Median PFS and OS were 5.7 months (6-month PFS rate: 44%) and 17 months (12-month OS rate: 62%), respectively. Programmed cell death ligand-1 (PD-L1) expression was associated with improved ORR, but not OS or PFS. Conclusions: Combination pembrolizumab and doxorubicin has manageable toxicity and preliminary promising activity in treatment of patients with anthracycline-naive advanced STS.

    Abstract: Further advances of targeted cancer therapy require comprehensive in-depth profiling of somatic mutations that are present in subpopulations of tumor cells in a clinical tumor sample. However, it is unclear to what extent such intratumor heterogeneity is present and whether it may affect clinical decision-making. To study this question, we established a deep targeted sequencing platform to identify potentially actionable DNA alterations in tumor samples. METHODS We assayed 515 formalin-fixed paraffin-embedded (FFPE) tumor samples and matched germline DNA (475 patients) from 11 disease sites by capturing and sequencing all the exons in 201 cancer-related genes. Mutations, indels, and copy number data were reported. RESULTS We obtained a 1000-fold mean sequencing depth and identified 4794 nonsynonymous mutations in the samples analyzed, of which 15.2% were present at & lt;10% allele frequency. Most of these low level mutations occurred at known oncogenic hotspots and are likely functional. Identifying low level mutations improved identification of mutations in actionable genes in 118 (24.84%) patients, among which 47 (9.8%) otherwise would have been unactionable. In addition, acquiring ultrahigh depth also ensured a low false discovery rate ( & lt;2.2%) from FFPE samples. CONCLUSIONS Our results were as accurate as a commercially available CLIA-compliant hotspot panel but allowed the detection of a higher number of mutations in actionable genes. Our study reveals the critical importance of acquiring and utilizing high sequencing depth in profiling clinical tumor samples and presents a very useful platform for implementing routine sequencing in a cancer care institution.
