    Abstract: Five percent to 9% of pancreatic ductal adenocarcinomas (PDACs) develop in patients with a germline BRCA1/2 or PALB2 (g BRCA/PALB2+) mutation. Phase IB data from a trial that used cisplatin, gemcitabine, and veliparib treatment demonstrated a high response rate (RR), disease control rate (DCR), and overall survival (OS) in this population. We designed an open-label, randomized, multicenter, two-arm phase II trial to investigate cisplatin and gemcitabine with or without veliparib in g BRCA/PALB2+ PDAC. PATIENTS AND METHODS Eligible patients had untreated g BRCA/PALB2+ PDAC with measurable stage III to IV disease and Eastern Cooperative Oncology Group performance status of 0 to 1. Treatment for patients in arm A consisted of cisplatin 25 mg/m 2 and gemcitabine 600 mg/m 2 intravenously on days 3 and 10; treatment for patients in arm B was the same as that for patients in arm A, and arm A also received veliparib 80 mg orally twice per day on days 1 to 12 cycled every 3 weeks. The primary end point was RRs of arm A and arm B evaluated separately using a Simon two-stage design. Secondary end points were progression-free survival, DCR, OS, safety, and correlative analyses. RESULTS Fifty patients were evaluated by modified intention-to-treat analysis. The RR for arm A was 74.1% and 65.2% for arm B ( P = .55); both arms exceeded the prespecified activity threshold. DCR was 100% for arm A and 78.3% for arm B ( P = .02). Median progression-free survival was 10.1 months for arm A (95% CI, 6.7 to 11.5 months) and 9.7 months for arm B (95% CI, 4.2 to 13.6 months; P = .73). Median OS for arm A was 15.5 months (95% CI, 12.2 to 24.3 months) and 16.4 months for arm B (95% CI, 11.7 to 23.4 months; P = .6). Two-year OS rate for the entire cohort was 30.6% (95% CI, 17.8% to 44.4%), and 3-year OS rate was 17.8% (95% CI, 8.1% to 30.7%). Grade 3 to 4 hematologic toxicities for arm A versus arm B were 13 (48%) versus seven (30%) for neutropenia, 15 (55%) versus two (9%) for thrombocytopenia, and 14 (52%) versus eight (35%) for anemia. CONCLUSION Cisplatin and gemcitabine is an effective regimen in advanced g BRCA/PALB2+ PDAC. Concurrent veliparib did not improve RR. These data establish cisplatin and gemcitabine as a standard approach in g BRCA/ PALB2+ PDAC.

    Abstract: Early detection and management of symptoms in patients with cancer improves outcomes. However, the optimal approach to symptom monitoring and management is unknown. InSight Care is a mobile health intervention that captures symptom data and facilitates patient-provider communication to mitigate symptom escalation. PATIENTS AND METHODS: Patients initiating antineoplastic treatment at a Memorial Sloan Kettering regional location were eligible. Technology supporting the program included the following: a predictive model that identified patient risk for a potentially preventable acute care visit; a secure patient portal enabling communication, televisits, and daily delivery of patient symptom assessments; alerts for concerning symptoms; and a symptom-trending application. The main outcomes of the pilot were feasibility and acceptability evaluated through enrollment and response rates and symptom alerts, and perceived value evaluated on the basis of qualitative patient and provider interviews. RESULTS: The pilot program enrolled 100 high-risk patients with solid tumors and lymphoma (29% of new treatment starts v goal of 25%). Over 6 months of follow-up, the daily symptom assessment response rate was 56% (the goal was 50%), and 93% of patients generated a severe symptom alert. Patients and providers perceived value in the program, and archetypes were developed for program improvement. Enrolled patients were less likely to use acute care than were other high-risk patients. CONCLUSION: InSight Care was feasible and holds the potential to improve patient care and decrease facility-based care. Future work should focus on optimizing the cadence of patient assessments, the workforce supporting remote symptom management, and the return of symptom data to patients and clinical teams.

    Abstract: 2027 Background: Early detection and management of symptoms in patients with cancer improves outcomes, however, the optimal approach to symptom monitoring and management is unknown. This pilot program uses a mobile health intervention to capture and make accessible symptom data for high-risk patients to mitigate symptom escalation. Methods: Patients initiating antineoplastic treatment at a Memorial Sloan Kettering regional location were eligible. A dedicated staff of RNs and nurse practitioners managed the patients remotely. The technology supporting the program included: 1) a predictive model that identified patients at high risk for a potentially preventable acute care visit; 2) a patient portal enabling daily ecological momentary assessments (EMA); 3) alerts for concerning symptoms; 4) an application that allowed staff to review and trend symptom data; and 5) a secure messaging platform to support communications and televisits between staff and patients. Feasibility and acceptability were evaluated through enrollment (goal ≥25% of new treatment starts) and response rates (completion of 〉 50% of daily symptom assessments); symptom alerts; perceived value based on qualitative interviews with patients and providers; and acute care usage. Results: Between October 15, 2018 and July 10, 2019, the pilot enrolled 100 high-risk patients with solid tumors and lymphoma initiating antineoplastic treatment (median age: 66 years, 45% female). This represented 29% of patients starting antineoplastics. Over six months of follow-up, the response rate to the daily assessments was 56% and 93% of patients generated a severe symptom alert (Table). Both patients and providers perceived value in the program and 5,010 symptom-related secure messages were shared between staff and enrolled patients during the follow-up period. There was a preliminary signal in acute care usage with a 17% decrease in ED visits compared to a cohort of high-risk unenrolled patients. Conclusions: This pilot program of intensive monitoring of high-risk patients is feasible and holds significant potential to improve patient care and decrease hospital resources. Future work should focus on the optimal cadence of EMAs, the workforce to support remote symptom management, and how best to return symptom data to patients and clinical teams. [Table: see text]

    Abstract: 4154 Background: ctDNA provides opportunities for identifying targeted therapies, a source to conduct NGS when tissue acquisition is infeasible, detection of minimal residual disease (MRD), and identification of resistance mutations. There are limited large data sets to inform clinical utility and limited correlation of NGS of ctDNA and tumor in PC. Herein, we evaluate the ctDNA detection rate in multiple cohorts of PC and report the ctDNA-tissue genotype concordance in PC at Memorial Sloan Kettering (MSK). Methods: Pts with PC at MSK who had ctDNA prospectively collected using the MSK-ACCESS 129 gene ctDNA NGS assay, were identified. ctDNA detection was defined as the identification of a mutation, copy number (no.) alteration or structural variant. Tissue-based NGS using MSK-IMPACT gene assay was performed for pts with adequate tissue, and matched with ctDNA by date. Clinical, pathologic and outcome data were abstracted. Data are summarized with descriptive statistics. Overall survival (OS) estimated by Kaplan-Meier method from date of ctDNA draw to death/last follow up. Results: From 08/2019 to 07/2022, N= 414 pts with PC and ≥ 1 ctDNA sample included. Median age 69 years (range 29-92), female N=206 (50%). Stage at ctDNA collection: Stage I-III N= 203 (49%); Stage IV N= 211 (51%). ctDNA detection rate by no. of involved organs; 0 organs (MRD), N=7/30 (23%); 1-2 organs, N=158/270 (58.5%); 3-4 organs, N=82/102 (80.4%); 〉 5 organs, 12/12 (100%). CtDNA detection rate by site of metastasis; Liver only, 75/99 (76%); peritoneum only, 15/25 (60%); lung only, 10/22 (45%). In pts with detected ctDNA median CA 19-9 was 494 U/mL (range 0, 247674) vs 100 U/mL (range 1, 22360) in pts with undetected ctDNA. In pts with detected ctDNA median CEA was 7 ng/mL (range 1, 2020) vs 4 ng/mL (range 1, 99) in pts with undetected ctDNA. In stage IV untreated pts, median OS 13 months(m) (95% CI; 7.3, 16) and 10 m (95% CI; 5.6, -) for ctDNA detected vs undetected, respectively. ctDNA detection rates by stage, and concordance between ctDNA and tissue-based NGS for common driver mutations KRAS, TP53, CDKN2A and SMAD4 in N=131 matched pairs are summarized in the table. Conclusions: ctDNA detection rates are high (89%) in pts with untreated stage IV PC, with high concordance between ctDNA and tissue-based NGS (87% - 95%). In untreated stage I-III PC, detection and concordance rates are lower ( 〈 50%). Detection rates are associated with disease burden, site of metastasis, CA 19-9/CEA levels. ctDNA is a promising tool in detection of somatic alterations in PC, particularly in stage IV disease, and is a complementary adjunct to tumor-based NGS.

    Abstract: 639 Background: gBRCA 1,2 mutations occur in 5-8% PDAC. Platinum and poly-ADP ribose polymerase inhibitors (PARPi) effective in BRCA-mut cancers. Phase I GC + V high RR 78%; combination may delay resistance in PDAC (O’Reilly, Cancer, 2018). Herein, we evaluate GC +/- V in a multi-national, randomized phase II trial. Methods: Eligibility: Untreated germline (g)BRCA, PALB2 mut PDAC; measurable stage III/IV; ECOG 0-1. Randomized 1:1 Arm A or B. Treatment: Arm A: G 600 mg/m2 IV, C 25 mg/m2 IV, d3 and 10, V 80 mg PO BID day 1-12, all q 3 weeks or Arm B: GC only. Primary endpoint: RECIST 1.1 response rate (RR). Simon 2-stage per arm: null hypothesis 10% vs promising 28%; type I, II error 10%. Secondary endpoints: progression-free survival (PFS), OS (m), disease control rate (CR+PR+SD), safety and correlative analyses. PFS, OS compared between arms using log-rank test and RR, DCR using Fisher’s exact test between arms. Results: N = 52 enrolled 01/14- 11/18. N = 2 withdrew Arm B. N = 50 for ITT. Male = 22 (44%), Female = 28. Median age = 64 years (range 37-82). BRCA1 N = 12, BRCA2 N = 35, PALB2 N = 3. Stage III N = 8; Stage IV N = 42. Hematologic Toxicity: Arm A vs Arm B: Gd 3-4 neutropenia 13 (48%) vs 7 (30%); Gd 3-4 platelets 15 (55%) vs 2 (9%); Gd 3-4 anemia 14 (52%) vs 8 (35%). Non-hematologic toxicity similar Arm A vs B. Exploratory analyses (combined Arms): Med OS if 〉 4 m platinum → PARPi: 23 m (95%CI 6.5- 53.9). Med OS by BRCA: BRCA1: 14 m (8.1- 18.5); BRCA2: 20.2 m (12.3- 24.4). Med OS by ECOG: ECOG 0: 23 m (13.8- 24.5); ECOG 1: 14.3 (8.1 vs 16.4). Two-year OS rate for entire cohort: 30.6% and 3-year OS: 17.8%. Conclusions: GC +/- V very active in gBRCA/PALB2 mut PDAC with high RR, PFS, OS with both A, B significantly exceeding threshold RR. Improved DCR arm A vs B, but with greater heme toxicity A vs B. Study confirms GC as reference treatment in gBRCA/PALB2 with durable survival in subset. Funding: National Cancer Institute, CTEP, Lustgarten Foundation, AbbVie.

    Abstract: e16082 Background: Clonal hematopoiesis (CH) represents non-random clonal selection of bone marrow-derived cells marked by somatic mutations in certain genes. The presence of CH is associated with development of atherosclerosis and leukemia, and accelerated by toxic exposures (chemotherapy, radiation, smoking) and aging (Jaiswal et al. NEJM 2017; Abelson et al. Nature 2018). The impact of these genetic alterations on cellular function is unknown, especially in the broader context of immunity and in response to cancer therapy. To determine the contribution of CH to therapeutic response and hematologic toxicity in cancer patients, we examined the outcomes of patients treated with cytotoxic and immunotherapy in relationship to CH status. Methods: We evaluated patients with metastatic colorectal cancer (CRC) or esophagogastric cancer (EGC). DNA extracted from whole blood and tumor tissue were sequenced in tandem as part of the MSK-IMPACT hybridization capture-based sequencing assay. CH was defined as any mutation with a VAF of at least 2%, present in at least 10 reads, with at least 2:1 blood:tumor reads, or 1.5:1 blood:lymph node that was not found in gnomAD with a frequency 〉 0.005. Additional filtering and putative driver definitions (CH-PD) were described by Bolton et al. Nature Genetics 2020. Multivariate survival analyses were performed using a Cox Proportional Hazard model correcting for CH, CH-PD, prior smoking, prior chemotherapy, prior radiation, MSI status, and age at cancer diagnosis. Results: 654 patients with EGC (n = 348) and CRC (n = 306) who began treatment between 2006 and 2020 were included in the analysis. CH was present in 34.5% and 24.4% of each group, and 17.2% and 12.9% harbored CH-PD, respectively. CH and CH-PD were both associated with older age and smoking history, and CH was also associated with prior radiation and MSI-high status (p 〈 0.05). Patients with CH or CH-PD receiving first-line (1L) therapy for CRC or EGC demonstrated no difference in mPFS after multivariate analysis, though 1L EGC patients with CH-PD had inferior mOS (p = 9e-5). There was no difference in pre-1L WBC, ANC, or ALC, nor in G-CSF or PEG-G-CSF doses administered during 1L therapy between patients with CH or CH-PD versus those without. Similarly, presence of CH or CH-PD had no impact on mPFS or mOS in patients receiving immune checkpoint blockade (ICB) without concurrent chemotherapy after multivariate survival analysis. Conclusions: We confirmed that the mere presence of CH is not prognostic for overall survival, but that EGC patients with CH-PD mutations have inferior overall survival, which is consistent with previous findings. Presence of CH or CH-PD was not associated with differences in baseline leukocyte counts nor need for G-CSF support, nor did it impact PFS in either tumor type, suggesting limited utility of CH in solid tumor clinical decision-making.

    Abstract: 1578 Background: Acute care visits (emergency department [ED] visits or inpatient admissions) for patients with cancer are growing disproportionately. Traditional oncology care models have not effectively identified and managed at-risk patients to prevent acute care. A next step is to harness advances in technology and mobile applications to enable patients to report symptoms any time, enabling “digital hovering” - intensive monitoring and management of high-risk patients. Our objective was to evaluate a digital platform that identifies and remotely monitors high-risk patients initiating intravenous antineoplastic therapy with the goal of preventing unnecessary acute care visits. Methods: This was a single-institution matched cohort quality improvement study conducted at an NCI-designated cancer center between January 1, 2019 and March 31, 2020. Eligible patients were those initiating intravenous antineoplastic therapy who were identified as high-risk for seeking acute care. Patients were identified as high-risk for an acute care visit by their oncologist with decision support from a web-based machine learning model. Enrolled patients’ symptoms were monitored using a digital platform. The platform is integrated into the EMR and includes: 1) a secure patient portal enabling communication and daily delivery of electronic patient-reported outcomes symptom assessments; 2) clinical alerts for concerning symptoms; and 3) a symptom trending application. A dedicated team of registered nurses and nurse practitioners managed reported symptoms. These clinicians acted as an extension of the primary oncology team, assisting with patient management exclusively through the platform. The primary outcomes evaluated were incidence of ED visits and inpatient admissions within six months of intravenous antineoplastic initiation. Results: Eighty-one high-risk patients from the intervention arm were matched by stage and disease with contemporaneous high-risk control patients. Matched cohorts had similar baseline characteristics, including age, sex, race, and treatment. ED visits and hospitalizations within six months of treatment initiation were analyzed using cumulative incidence analyses with a competing risk of death. The cumulative incidence of an ED visit for the intervention cohort was 0.27 (95% CI: 0.17, 0.37) at six months compared to 0.47 (95% CI: 0.36, 0.58) in the control group (p = 0.01). The cumulative incidence of an inpatient admission was 0.23 (95% CI: 0.14, 0.33) in the intervention group versus 0.41 (95% CI: 0.30, 0.51) in the control group (p = 0.02). Conclusions: The narrow employment of technology solutions to complex care delivery challenges in oncology can improve outcomes and innovate care. This program was a first step in using a digital platform and a remote team to improve symptom care in the home for high-risk patients.

    Abstract: 6535 Background: Monitoring and managing patient reported outcomes (PROs) has been recommended for oncology patients on active treatment but can be time and resource intensive. Identifying patients likely to benefit and the optimal frequency of PRO capture is still under investigation. We tested the feasibility of monitoring patients who are high-risk risk for acute care with daily PROs. Methods: Using data from our institution, we developed a model that employs over 400 clinical variables to calculate a patient’s risk of an emergency room visit within 6 months following the onset of treatment. From October 15, 2018 to January 23, 2019, we enrolled patients identified as high risk through a technology-enabled program to monitor and manage those patients’ symptoms. Enrolled patients entered PRO assessments daily via an online portal. Symptoms were monitored and managed by a centralized clinical team. Tiered notifications informed the team of concerning or escalating symptoms. We assessed how frequently patients completed symptom assessments and the frequency of symptom notifications. Results: During the pilot, 28 patients were identified as high risk and enrolled in the program (median age 65; 64% percent female). Disease types were: 15 (54%) thoracic, 7 (25%) gynecologic, 6 (21%) gastrointestinal. Median time in the program was 50 (6-98) days. Patients completed 840 of 1,350 assessments (62%). There were 328 assessments that triggered moderate alerts (39%) and 220 that triggered severe alerts (26%). The table describes the prevalence of symptoms at the patient-level. Conclusions: A model can be employed to identify high-risk patients in collaboration with clinicians. Our adherence rate with a daily symptom assessment was similar to those found in studies of less frequent PRO capture. Future work will expand to a larger patient population with other cancer types, evaluate impact on outcomes, and assess optimal frequency for PRO collection and alert thresholds. [Table: see text]

    Abstract: 405 Background: PEGPH20 (P) degrades hyaluronan (HA), a key component of pancreatic adenocarcinoma (PDAC) tumor microenvironment, leading to reduction of tumor interstitial pressure, decompression of tumor blood vessels and improvement in delivery of chemotherapeutics. A prior study of P with chemotherapy in PDAC (HALO-202) found an increased risk of thromboembolic (TE) events, 43%, effectively reduced with subcutaneous enoxaparin treatment. Rivaroxaban (R) is a safe and effective oral anticoagulant for treating cancer-related TE. Methods: 28 patients with advanced PDAC, KPS ≥ 70 and without prior TE were enrolled from January to June 2017. Patients received treatment with PAG (P; 3 µg/kg IV 2x/wk x 3 wks in C1, then 1x/wk x 3 wks in C2+, plus AG) every 28 days, with R (15 mg twice daily for 21 days, followed by 20 mg once daily). Primary endpoint is symptomatic TE event rate; secondary endpoints include PFS, OS, major bleeding rate and RR. Results: All 28 patients are evaluable for efficacy and safety. Key patient characteristics: age = 62 (range 45-76), M/F = 15/13, stage III/IV = 4/24, KPS 70/80/90 = 1/13/14. Median follow-up is 5.4 mo. No symptomatic and one grade 2, asymptomatic TE event (DVT) occurred (1/28 = 3.6%). Two grade 3 GI hemorrhages occurred. Best responses: partial response 11 (39%), stable disease 13 (46%), progressive disease 4 (14%), and overall disease control rate of 86%. Median PFS and OS have not been reached. Conclusions: Interim analysis shows R is safe and effectively prevents TE events in patients receiving PAG. Responses and disease control rate are encouraging in this tumor HA-level unselected patient population. Updated safety and efficacy data will be reported. Clinical trial information: NCT02921022.
