TPS10085 Background: Novel checkpoint inhibitors are a promising treatment for advanced melanoma, as only a fraction of patients have durable responses to current FDA-approved immunotherapy. Lymphocyte activation gene 3 (LAG3) is an inhibitory checkpoint receptor on CD4+ and CD8+ T cells, where engagement results in suppression of T cell activation and proliferation. LAG3 and PD1 are co-expressed on T cells during T cell receptor signaling and are down-regulated after antigen clearance. Persistent stimulation leads to prolonged LAG3 and PD1 expression and to T cell exhaustion, a possible mechanism of resistance to immunotherapy. Both LAG3 and PD1 are expressed on tumor-infiltrating T cells in melanoma. Murine tumors treated with both anti-LAG3 and anti-PD1 have demonstrated increased tumor regression than tumors in mice treated with either single agent. Further, a phase I trial has demonstrated safety of combined anti-LAG3 monoclonal antibody, relatlimab and anti-PD1 monoclonal antibody, nivolumab. Methods: This phase II, single-center clinical trial is designed to enroll treatment naive patients with unresectable or metastatic melanoma to ultimately receive combined relatlimab and nivolumab after a lead-in arm where patients are randomized to receive relatlimab, nivolumab, or the combination for the first 4 week cycle. For the lead-in phase, patients will have baseline and post-treatment blood and tumor sampling. Disease assessment by imaging will occur after the lead-in phase at 4 weeks. After completion of the lead-in phase, all patients proceed to combination therapy with disease assessment at 12-week intervals. The primary endpoint for the lead-in phase is to evaluate changes in immune cell populations in peripheral blood and tumor with the single agents and combination treatment. The primary endpoint for the combination phase is best overall anti-tumor response. Secondary clinical endpoints include progression-free survival, overall survival, duration of response and toxicity. Exploratory endpoints are to determine the mechanistic effects of anti-LAG3 and anti-PD1 on the blood and tumor microenvironment, cytokine signatures, and correlation of these with clinical response. The study is currently accruing with enrollment of 9 out of 42 patients. Clinical trial information: NCT03743766.

TPS1114 Background: Immunotherapy combined with chemotherapy is being studied in metastatic breast cancer, and may have durable outcomes. Chest wall recurrence represents a difficult to treat subtype of breast cancer with a poor prognosis, with lymphovascular invasion in the primary tumor a significant risk factor. Given the inflammatory nature of this disease and the association of programmed cell death 1 (PD-1) expression with lymphovascular invasion, we hypothesized that the combination of pembrolizumab, an anti-PD-1 antibody, with carboplatin may be effective as treatment for breast cancer chest wall recurrences. Methods: This randomized phase II study is enrolling 84 patients with breast cancer involving the chest wall, who may also have distant metastases. Patients receive treatment with pembrolizumab 200 mg and carboplatin AUC 5 every 3 weeks for 6 cycles (Arm A, n = 56) followed by maintenance pembrolizumab +/- carboplatin (Arm Ax), or carboplatin AUC 5 every 3 weeks for 6 cycles (Arm B, n = 28) with an option to cross-over to pembrolizumab +/- carboplatin on progression (Arm Bx). Patients with all disease subtypes, triple-negative, hormone receptor positive/HER2- after 2 prior lines of hormone therapy, and HER2+ disease (with the option to continue trastuzumab) are eligible, with no limit on the number of prior therapies. Prior platinum chemotherapy is allowed in the absence of overt disease progression. Patients undergo clinical assessment with every cycle of treatment including chest wall photography, scans (CT chest, abdomen, and pelvis) every 2 cycles, and have peripheral blood and chest wall biopsies collected at baseline and the start of cycle 3 for correlative studies. The primary endpoint is the disease control rate in the chest wall and distant sites at 18 weeks of treatment based on RECIST 1.1. The study is powered to determine a 20% difference in disease control between arms (hazard ratio 0.52, α = 0.10, β = 0.20). Additional endpoints include response by tumor programmed death ligand 1 (PD-L1) status and irRECIST, progression-free survival, and toxicity. Chest wall tumor samples will be analyzed for changes in tumor immune composition, and PD-L1 and MYC oncogene expression, based on preclinical data to suggest that PD-L1 may be upregulated by MYC. Peripheral blood samples will be evaluated for changes in PD-L1 expression, cell-free DNA, and circulating tumor cells with treatment. The study is enrolling patients at 7 sites within the Translational Breast Cancer Research Consortium (TBCRC), with current enrollment of 38/84 patients. Clinical trial information: NCT03095352 .

TPS11567 Background: Ewing sarcoma (ES) is a rare, aggressive bone and soft tissue cancer that predominantly afflicts adolescents and young adults. Novel therapeutic agents are needed as there are no approved targeted treatments for this disease. ES is characterized by a chromosomal translocation resulting in an EWS/ETS fusion oncoprotein, a transcription factor that results in aberrant gene expression leading to ES progression. Lysine specific demethylase 1 (LSD1) associates with EWS/ETS oncoproteins to alter gene expression and contribute to disease progression. Directly inhibiting EWS/ETS is challenging and little progress has been made, though targeting LSD1 presents a viable therapeutic strategy for ES. Seclidemstat (SP-2577, Salarius Pharmaceuticals) is a first-in-class, orally bioavailable, small molecule with reversible and noncompetitive selective inhibition of LSD1 at low nanomolar concentrations (IC50: 25-50 nM). Seclidemstat inhibits LSD1’s scaffolding functions and enzymatic activity to help reverse aberrant gene expression. In vitro data show that treatment with seclidemstat, or seclidemstat analog, modulates EWS/ETS transcriptional activity, down-regulating oncogene expression and up-regulating tumor-suppressor gene expression. In in vivo xenograft studies (e.g., SK-N-MC, A673), mice treated with seclidemstat show significant tumor growth inhibition/regression vs the control vehicle group. Methods: This phase 1/2 clinical study of seclidemstat is being conducted in relapsed or refractory ES (NCT03600649). The trial is an open-label, non-randomized dose-escalation/dose-expansion study designed to determine the maximum tolerated dose through single-patient dose escalation followed by traditional 3+3 design. The primary objective is to assess seclidemstat’s safety and tolerability while secondary objectives include pharmacokinetics, efficacy and exploratory pharmacodynamic markers. Patients must be ≥12 years old, have received at least 1 prior line of therapy including a prior camptothecin-based regimen, with a life expectancy > 4 months. All patients receive seclidemstat twice-daily (BID) as oral tablets until unacceptable toxicity or disease progression. Patients are followed for survival until the end of study. The trial is currently recruiting across 8 locations in the United States. Upon identification of the recommended phase 2 dose, that cohort will be expanded to enroll a total of 20 patients. Clinical trial information: NCT03600649 .

TPS11569 Background: ADP-A2M4 specific peptide enhanced affinity receptor (SPEAR) T-cells are genetically engineered to target MAGE-A4+ tumors in the context of HLA-A*02. MAGE-A4 has been described as having high expression in synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCLS) [1, 2]. This Phase 2 trial was initiated based on the favorable benefit:risk profile of ADP-A2M4 observed in a Phase 1 trial (NCT03132922) of ADP-A2M4 which demonstrated compelling clinical responses in patients with SS. Methods: This Phase 2, open-label trial (SPEARHEAD-1; NCT04044768) is designed to evaluate the efficacy, safety and tolerability of ADP-A2M4 in patients with advanced/metastatic SS or MRCLS who are HLA-A*02 positive and whose tumors express the MAGE-A4 protein. Enrolled patients are to undergo apheresis, and their isolated T-cells are then transduced with the MAGE-A4c1032 TCR, and expanded. Prior to ADP-A2M4 infusion, patients are to receive lymphodepleting chemotherapy consisting of fludarabine (30 mg/m2/day x 4 days) and cyclophosphamide (600 mg/m2/day x 3 days). Patients are to receive 1 – 10 × 109 transduced T-cells. An independent Data Safety Monitoring Board will review ongoing safety and benefit:risk during the interventional phase of the study. Disease will be assessed by independent review per RECIST v1.1 by CT/MRI at weeks 4, 8, 12, 16, 24, and every 2 months thereafter until confirmed disease progression. As of 24 Jan 2020, there were 17 clinical sites open in the US, one in Canada, and two in Spain. References: 1. Iura K, et al.

TPS12125 Background: Neurotoxicity is one of the most significant and disabling side effects of oxaliplatin and frequently limits the cumulative amount that can be used. The mechanism of oxaliplatin-induced neurotoxicity remains uncertain, although our preliminary studies suggest that oxaliplatin uptake by organic cation transporter 2 (OCT2) into mouse and rat dorsal root ganglion is a prerequisite for oxaliplatin-induced peripheral neuropathy. The activity of OCT2 is dependent on tyrosine phosphorylation by the SRC-kinase family member Yes1, which is highly sensitive to inhibition by several FDA-approved, small molecule kinase inhibitors such as dasatinib. We have previously shown that pre-treatment with oral dasatinib prevented acute and chronic oxaliplatin-induced peripheral neuropathy in mouse and rat models. Methods: This is a phase Ib dose-finding study of dasatinib given in combination with mFOLFOX6 with or without bevacizumab. The study explores the hypothesis that the addition of dasatinib prior to oxaliplatin will inhibit OCT2 activity and reduce oxaliplatin-induced neuropathy. This hypothesis will be tested in a Bayesian Phase 1b trial with adaptive dose selection using efficacy-toxicity trade-offs (modified toxicity-efficacy probability interval dose-finding design) in patients with confirmed stage IV colorectal cancer who are candidates for mFOLFOX6 with bevacizumab therapy. Patients who have documented peripheral neuropathy or prior exposure to oxaliplatin will be excluded. The primary objective is to determine the recommended Phase 2 dose which is defined as the lowest intermittent dose of dasatinib that affects serum biomarkers of OCT2, including methylnicotinamide and creatinine, by ≥2-fold without influencing the clearance of oxaliplatin by > 20%. The following doses will be used: oxaliplatin 85mg/m2 IV, 5FU bolus 400mg/m2 IV bolus with Leucovorin 400mg/m2, bevacizumab 5mg/kg, followed by infusional 5FU 2400mg/m2 IV over 46 hours given on a day 1 and 15 schedule every 28 days. Dasatinib will be administered at one of 2 dose levels – 100mg or 140mg po. Dasatinib will be given 24 hours and 30 mins prior to oxaliplatin on C1D14, C1D15 respectively and repeated on C1D28 and C2D1. Secondary objectives include evaluation of the influence of dasatinib on the pharmacokinetics of oxaliplatin and vice versa. Quality of life will be explored using the CIPN20 questionnaire. The trial opened to enrollment in Dec 2019 (NCT04164069) and is accepting patients. Clinical trial information: NCT04164069 .

TPS12126 Background: The undertreatment of pain in patients with advanced or metastatic cancer is well described in cancer research. Overcoming barriers that prevent successful use of opioid analgesics for cancer pain requires a clear understanding of how individuals use oral medications at home. The Proteus Discover is a digital medicine program (DMP) consisting of an FDA-approved ingestible sensor made of dietary minerals co-encapsulated with patients’ medications, a wearable sensor patch, and a mobile device app that enables patients to electronically transmit their medication adherence patterns. Use of the DMP has demonstrated improved clinical outcomes vs. usual care in patients with diabetes and hypertension, shown superiority over directly-observed therapy in tuberculosis and has been studied in the treatment of patients with hepatitis C, HIV, cancer and severe mental illness, but it has not been previously studied with opioids or in monitoring cancer-related pain. Methods: We are conducting a multicenter pilot study at SWOG NCORP sites to test the feasibility of using the DMP to monitor opioid use in the treatment of metastatic cancer pain. Eligible patients must have a diagnosis of metastatic cancer, have a baseline Brief Pain Inventory worst pain score of ≥3, be deemed by their physician to need initiation or up-titration of oxycodone-acetaminophen for pain control, and be able to read English. Primary outcomes include: (1) study accrual of 60 patients within six months of study activation at all participating sites; (2) patient retention defined as ≥50 patients completing the study, and; (3) adherence to the DMP defined as ≥66% of patients wearing the sensor patch for ≥28 days of the 42-day observation period. Secondary outcomes include change in Brief Pain Inventory pain scores, opioid medication consumption, number of safety alert triggers for high consumption, hospital or emergency room visits for pain, activity levels, and frequency of changes to the pain control regimen. The study will enroll patients at six sites; the first patient was enrolled on 1/20/2020. If successful, this study will inform design of a randomized controlled trial of the DMP vs. usual care in optimizing medication utilization and controlling cancer-related pain.

Published: May 2020

TPS1597 Background: This randomized trial is intended to determine whether tomosynthesis (TM) should replace the current standard for breast cancer (BC) screening, digital mammography (DM). It is hypothesized that the population of women assigned TM screening for 3-5 rounds will have fewer advanced cancers than the population assigned to DM screening. Methods: 164,946 women, ages 45 to 74 years who present for screening mammography and consent to participate will be enrolled across 150 sites in the US, Canada and abroad. Women will be randomized to TM or DM. The frequency and number of screening examinations over a five year period will vary based on menopausal status and whether they have specific risk factors, including - hormone use, family history of BC, deleterious genes, prior benign breast biopsy with diagnosis of LCIS or atypia any kind, or dense breasts. Blood and buccal cells will be collected from as many enrolled women as are willing to provide the samples. All breast biopsies during the trial will undergo gene expression analysis for the PAM50 and other progression pathways (PAM50-plus). All subjects enrolled will be followed long term for at least eight years. The primary endpoint is the proportion of participants who have an advanced breast cancer diagnosed at any time within 4.5 years of randomization in to the trial. Secondary endpoints include measures of diagnostic and predictive performance; rates of recall, biopsy, and interval cancers, prevalence of breast cancer subtypes, and tumor subtype based on PAM50-plus analysis. As of January 17th 2020, there are 104 sites open and 21,452 women enrolled in the trial. The DSMC last reviewed the trial in June 2019 and suggested that the trial continue as planned. Clinical trial information: NCT03233191.

TPS2087 Background: Making personalized diagnostics and treatments a reality for every cancer patient necessitates comprehensively capturing the patient journey. Real-world data has shown promise for the future of clinical research and advancing precision medicine. However, certain limitations exist such as data quality management as well as bias and confounding factors associated with retrospective analyses. We present a multi-stakeholder platform to prospectively collect and link real-world clinico-genomic, imaging, and outcomes data to longitudinal blood genomic profiling for lung cancer. Methods: This study is enrolling approximately 1000 patients with metastatic non-small cell lung cancer or extensive-stage small cell lung cancer who will initiate standard-of-care systemic anti-neoplastic treatment, regardless of line of therapy, at 20 community oncology and academic practices within the Flatiron Health network. Relevant clinical data points from both structured and unstructured fields will be collected through the electronic health records via technology-enabled abstraction, eliminating the need for case report forms. Digital pathology and clinical images at standard-of-care visits will be collected. Blood samples for circulating tumor DNA (ctDNA) profiling using FoundationOne Liquid will be collected at three timepoints: enrollment, first tumor assessment, and end of treatment. Tumor tissue samples may be submitted at baseline for genomic profiling using FoundationOne CDx. Overall survival follow-up will occur until death, withdrawal of consent, loss to follow-up, or end of study. The objectives are to evaluate 1) the feasibility of building a scalable, prospective platform and 2) the associations between ctDNA and real-world clinical outcomes, including overall survival. Enrollment is ongoing. Clinical trial information: NCT04180176.

TPS2088 Background: ICIs have become the therapeutic standard for many cancers but are associated with unique and diverse irAEs that often occur at home. Appropriately timed and specific interventions are critical to recovery. Thus, there is a need to effectively & efficiently monitor in real time pts treated with ICIs. To improve outcomes, we have activated a clinical trial developed to determine the feasibility and safety of an electronically enabled strategy to remotely monitor symptoms and prompt communication that will guide and inform specific patient-driven “course corrections” in response to potential irAEs. Methods: This is an adaptive prospective trial that uses a mobile irAE-specific PRO application we developed to monitor and alert the care team in real time when severe symptoms are reported. In parallel with the mobile symptom collection, serum and urine biomarkers are collected at baseline, first tumor restaging, and upon the development of irAEs. Optional stool microbiome analyses are also performed. To facilitate the generalizability of our inferences, we are using broad inclusion criteria: ECOG performance status ≤3; any line of ICI given as standard of care or as part of therapeutic clinical trials; elderly pts are included. Because the relationship between PROs and irAEs is currently undefined, we designed our trial to use adaptive symptom thresholds that will notify the healthcare team of suspicion for irAEs. The mobile application will use these dynamic thresholds to determine whether or not to alert the healthcare team. The positive and negative predictive value of each symptom for identifying subsequent irAEs will be assessed at scheduled interim analysis time points. The care teams’ responses to the alerts, and all of the clinical outcomes for the pts over time will be collected as part of the trial. The primary goal of the trial is the assessment of the predictive power of the mobile PRO symptom collection in combination with serum and urine markers to identify grade 2 or higher adverse events that require intervention (e.g., dose modifications, hospitalizations, and therapeutic interventions) within two weeks of symptom onset. Effective remote monitoring of irAEs will leverage our understanding of ICI toxicity and empower pts to be effective partners in their care. The trial has currently enrolled 17 pts towards the enrollment target of 100 pts. Clinical trial information: PA19-0095 .
