691 Background: The primary objective was to assess the effect of concomitant RAM on the PK of IRI and its metabolite SN-38 when coadministered with FA and 5-FU. Methods: Key eligibility criteria included pts aged ≥18 years with metastatic or locally advanced malignant solid tumors resistant to standard therapy or for which no standard therapy was available, and an Eastern Cooperative Oncology Group performance status of 0 to 2. Pts received intravenous infusions of FOLFIRI and RAM 8 mg/kg on day 1 of a 2-week cycle. FOLFIRI was administered alone in cycle 1; RAM was administered followed by FOLFIRI in all subsequent cycles. Blood for PK was collected at regular intervals after infusions in cycles 1 and 2 to determine IRI and SN-38 plasma concentrations. Pts who completed the first 2 cycles of study treatment were included in the drug-drug interaction (DDI) population. All pts who received at least 1 dose of RAM or FOLFIRI were included in the safety population. Results: The safety population comprised 29 pts, and the DDI population included 25 of these 29 pts. The dose-normalized area under the concentration versus time curve from zero to infinity [AUC(0-∞)] and the maximum observed drug concentration (Cmax) of IRI and SN-38 were comparable between cycle 1 (FOLFIRI alone) and cycle 2 (RAM+FOLFIRI). The ratios of geometric least-squares (LS) means for IRI were 0.93 (90% CI; 0.83, 1.05) for AUC(0-∞) and 1.04 (90% CI; 0.97, 1.12) for Cmax. The ratios of geometric LS means for SN-38 were 0.95 (90% CI; 0.88, 1.04) for AUC(0-∞) and 0.97 (90% CI; 0.85, 1.12) for Cmax. The most prevalent treatment-emergent adverse events (TEAEs) were fatigue/asthenia (n=19, 65.5%), diarrhea (n=16, 55.2%), neutropenia (n=15, 51.7%), nausea (n=14, 48.3%), and decreased appetite and anemia (n=13 each, 44.8%). Grade ≥3 TEAEs were rare, except for neutropenia in 7 (24.1%) pts. Conclusions: The PKs of IRI and its metabolite, SN-38, were not affected when coadministered with RAM. RAM with FOLFIRI was well-tolerated in this study without new safety concerns. Clinical trial information: NCT01634555.

TPS3153 Background: Ataxia telangiectasia and Rad3-related (ATR) protein kinase plays a critical role in the DNA damage response by sensing and responding to DNA replication stress, and by inducing cell cycle arrest to prevent aberrant replication and mitotic catastrophe. Based on extensive preclinical and limited clinical evidence, ATR inhibition is a promising treatment strategy as monotherapy for patients with advanced tumors harboring synthetically lethal conditions, such as alternative lengthening of telomeres (ALT) and inactivating mutations in ARID1A and ATM. M1774 is a potent, selective, orally administered ATR inhibitor that has been shown to exert antitumor activity in patient-derived xenograft tumors and acute myeloid leukemia xenograft tumors that express the ATR inhibition sensitizing mixed lineage leukemia fusion protein. This study (NCT04170153) aims to evaluate the safety and tolerability, maximum tolerated dose, recommended dose for expansion (RDE) and pharmacokinetics (PK) of M1774 (part A1), the effect of food on M1774 PK (part A2), and the efficacy of M1774 in patients with tumors harboring selected mutations (part A3). An additional objective is to assess the pharmacodynamics of M1774 by measuring relative changes in baseline p-CHK1 and γ-H2AX expression in paired tumor biopsies and serial blood samples. Methods: Patients aged ≥18 years, with an Eastern Cooperative Oncology Group performance status ≤1, adequate baseline hematological, renal and hepatic function, and with locally advanced or metastatic disease refractory to standard therapy are eligible. Patients with tumors bearing loss-of-function (LoF) mutations (determined by site testing or a central trial assay) in ARID1A, ATM, or ATRX and/or DAXX as ALT status surrogate markers; and measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, will be enrolled in part A3. In the dose escalation phase (part A1 [open]), 18–24 patients are due to receive M1774 at a starting dose of 5 mg once daily. Dose escalation is determined by the safety monitoring committee and guided by a Bayesian 2-parameter logistic regression model. The preliminary food assessment (part A2) will follow a randomized two-sequence two-period crossover design in which ≤12 patients will be randomized (1:1) to receive a single dose of M1774 on Day –7 at the RDE (determined in part A1) in either a fed or fasted condition. After the food assessment, patients will subsequently receive M1774 according to the part A1 dosing schedule. In the preliminary efficacy study (part A3), patients (n = 20–24 for each of the three planned cohorts) with tumors harboring LoF mutations in the genes for ARID1A, ATM, ATRX and/or DAXX, will receive M1774 at the RDE. The primary efficacy endpoint is overall response (RECIST). The study is open and currently recruiting. Patients have been enrolled to seven cohorts in part A1 with no DLTs observed; dose escalation is ongoing. Clinical trial information: NCT04170153.

Treatment Patterns

414 Background: There are a lack of published real-world data on treatment patterns for patients with locally advanced or metastatic urothelial carcinoma (la/mUC) previously treated with programmed death 1/ligand 1 inhibitor (PD-1/L1i) therapy. The objective of this study was to characterize the clinical characteristics and treatments among patients with la/mUC following discontinuation of first-line (1L) or second-line (2L) PD-1/L1i therapy. Methods: We performed a retrospective chart review at 26 geographically diverse clinical sites in the US. Patients aged ≥18 years with histologically or cytologically confirmed urothelial carcinoma and radiographic evidence of metastatic or locally advanced disease were identified. Included patients had initiated and subsequently discontinued PD-1/L1i therapy in the 1L or 2L setting for la/mUC between May 15, 2016-July 31, 2018. All patients had follow-up through October 31, 2019. Data were summarized using descriptive statistics. Results: Among the 300 patients included in the chart review, 198 (66%) received PD-1/L1i therapy as 1L and 102 (34%) as 2L therapy. Mean (SD) age at la/mUC diagnosis was 69.4 (8.7) years, and a majority of patients were male (66.0%) and White (74.7%). Consistent with age, most patients (82.7%) had comorbidities at la/mUC diagnosis; 39.7% hypertension, 23.7% coronary artery disease, 17.7% pulmonary disease, and 9.3% renal disease. At initiation of therapy, a higher proportion of patients who received 1L PD-1/L1i therapy had an Eastern Cooperative Oncology Group performance status of 2 or more than patients who received 2L PD-1/L1i therapy (36.8% vs 22.5%, respectively). Following discontinuation of PD-1/L1i therapy, 34% (n = 68) received subsequent therapy in 2L and 29% (n = 30) in third-line (3L). The most common subsequent therapies in 2L were gemcitabine monotherapy (24%), gemcitabine plus cisplatin or carboplatin (22%), PD-1/L1i therapy (22%), and taxane monotherapy (19%). The most common subsequent therapies received in 3L were taxane monotherapy (50%), pemetrexed (17%), and PD-1/L1i therapy (16%). Overall, switching from one PD-1/L1i therapy to another distinct PD-1/L1i therapy occurred in approximately 20% of patients, with “better efficacy/survival” noted by treatment teams as the most common reason for switching therapy among this subgroup. Conclusions: In this real-world case series, only a minority of patients with la/mUC who discontinued PD-1/L1i therapy received subsequent therapy. Among those that did, no clear standard of care was observed and approximately one-fifth of patients were treated with a second PD-1/L1i therapy after the first failed to control disease. Collectively, the data highlight significant unmet need for patients with la/mUC who discontinue PD-1/L1i therapy.

TPS477 Background: In pts with LAPC, more effective systemic therapies may be associated with improved local control, delay of metastasis, and overall survival (OS). The phase III MPACT trial in pts with metastatic PC demonstrated longer OS (median, 8.7 vs 6.6 mos; HR, 0.72; P < 0.001) and an ≈ 3-fold greater shrinkage of primary tumors with nab-P + Gem vs Gem alone (−22.15% vs −7.02%), raising the possibility of improved local PC control with nab-P + Gem. LAPACT will assess the efficacy and safety of nab-P + Gem in LAPC. Methods: LAPACT will enroll treatment-naive pts (planned n ≈ 110) in the United States, Canada, and Europe with Eastern Cooperative Oncology Group performance status ≤ 1, confirmed unresectable LAPC, no distant metastases, and adequate organ function. Pts with mixed-origin tumors, any other malignancy within 5 years, peripheral neuropathy grade > 1, or clinically significant ascites are ineligible. Pts will receive nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 of each 28-day cycle. Pts without progressive disease (PD) or unacceptable toxicity after 6 cycles will receive investigator’s choice of surgery, chemoradiotherapy, or continued nab-P + Gem. If a major response is observed, surgery may occur prior to completing 6 cycles of nab-P + Gem. The primary endpoint is time to treatment failure (TTF; time from first therapy dose to discontinuation due to PD, start of a new non–protocol-defined anti-cancer therapy, or death). The study design allows for 80% power at a 1-sided α of 0.05 to detect a 30% increase over the 5.1-month median TTF observed for nab-P + Gem in the MPACT study. The secondary endpoints are disease control rate (DCR) after 6 cycles, overall response rate, progression-free survival, OS, safety, and quality of life. The exploratory endpoint is correlation of changes in circulating nucleic acids with PD and treatment response. An interim DCR analysis will occur after all pts have completed 6 cycles of nab-P + Gem, discontinued therapy due to PD, died, or started a new non–protocol-defined therapy before completing 6 cycles of therapy. Enrollment is ongoing (first pt enrolled in April 2015). Clinical trial information: NCT02301143.

Purpose To provide evidence-based recommendations to oncologists and others for treatment of patients with locally advanced, unresectable pancreatic cancer. Methods American Society of Clinical Oncology convened an Expert Panel of medical oncology, radiation oncology, surgical oncology, gastroenterology, palliative care, and advocacy experts and conducted a systematic review of the literature from January 2002 to June 2015. Outcomes included overall survival, disease-free survival, progression-free survival, and adverse events. Results Twenty-six randomized controlled trials met the systematic review criteria. Recommendations A multiphase computed tomography scan of the chest, abdomen, and pelvis should be performed. Baseline performance status and comorbidity profile should be evaluated. The goals of care, patient preferences, psychological status, support systems, and symptoms should guide decisions for treatments. A palliative care referral should occur at first visit. Initial systemic chemotherapy (6 months) with a combination regimen is recommended for most patients (for some patients radiation therapy may be offered up front) with Eastern Cooperative Oncology Group performance status 0 or 1 and a favorable comorbidity profile. There is no clear evidence to support one regimen over another. The gemcitabine-based combinations and treatments recommended in the metastatic setting (eg, fluorouracil, leucovorin, irinotecan, and oxaliplatin and gemcitabine plus nanoparticle albumin-bound paclitaxel) have not been evaluated in randomized controlled trials involving locally advanced, unresectable pancreatic cancer. If there is local disease progression after induction chemotherapy, without metastasis, then radiation therapy or stereotactic body radiotherapy may be offered also with an Eastern Cooperative Oncology Group performance status ≤ 2 and an adequate comorbidity profile. If there is stable disease after 6 months of induction chemotherapy but unacceptable toxicities, radiation therapy may be offered as an alternative. Patients with disease progression should be offered treatment per the ASCO Metastatic Pancreatic Cancer Treatment Guideline. Follow-up visits every 3 to 4 months are recommended.

Abstract Purpose: The presence of a sarcopenia adversely affects the prognosis of patients with pancreatic cancer. There is an emerging role for using computed tomography (CT) to calculate skeletal muscle index (SMI) and the presence of sarcopenia. The aim of this study was to assess if detecting ‘digital sarcopenia’ is feasible and can contribute to the management of patients with locally advanced pancreatic cancer (LAPC).Methods: Patients diagnosed with LAPC referred for endoscopic ultrasound guided biopsy (EUS-B) by our regional cancer network were identified. Age, body mass index (BMI), and Eastern Cooperative Oncology Group performance status (ECOG-PS) was noted. CT images were analysed for SMI and the presence of sarcopenia. Decision outcomes on receiving chemotherapy or not were collected from the regional oncology database. Results: In total 51/204 (25%) patients with LAPC who underwent EUS-B were not given chemotherapy and received BSC only. The prevalence of sarcopenia (p=0.0003), age ≥ 75 years old (p=0.03) and ECOG-PS 2-3 (p=0.01) were significantly higher in the patents receiving BSC only. Logistic regression analysis demonstrated that SMI was the only independent associated factor identifying patients with LAPC who were treated with BSC only and not chemotherapy after adjusting for age and ECOG-PS. Conclusion: Our study has shown that digital skeletal muscle analysis at the time of a diagnostic CT for patients with pancreatic cancer is feasible and can detect sarcopenia and malnourished patients who are much less likely to take up chemotherapy. These patients could be triaged to oncology assessment prior to EUS-B to avoid unnecessary investigations.

BackgroundThe benefit of immune checkpoint inhibitors (ICIs) in patients with leptomeningeal metastases (LMM) is unknown.MethodsWe undertook a phase II trial of pembrolizumab in patients with LMM from solid tumors. Eligible patients had radiologic/cytologic LMM and Eastern Cooperative Oncology Group performance status 0–1. Pembrolizumab was administered intravenously at 200 mg q3W until disease progression/unacceptable toxicity. The primary endpoint was central nervous system (CNS) response after four cycles, defined radiologically/cytologically/clinically. Serial cerebrospinal fluid (CSF) was assessed for tumor-derived DNA (t-DNA) aneuploidy and cytokines.ResultsThirteen of a planned 16 patients were treated between April 2017 and December 2019. The study closed early for poor accrual. Median age was 57 years (range: 22–79). Sixty-two percent of patients had tumors not traditionally ICI-responsive (hormone-receptor (HR)-positive breast carcinoma=39%; high-grade glioma=23%), while 38% had ICI-responsive tumors (non-small cell lung cancer (NSCLC)=23%, head and neck carcinoma=8%, cutaneous squamous carcinoma (CSC)=8%). CNS response was observed in 38% of patients at 12 weeks (95% CI 13.9% to 68.4%) by pre-defined criteria and LM-RANO, and 2 achieved durable complete responses (CSC=1, overall survival (OS) 3+ years; NSCLC=1, OS 9 months). Median CNS progression-free survival and OS was 2.9 months (95% CI 1.3 to NR) and 4.9 months (95% CI 3.7 to NR), respectively. Grade 3+ treatment-related adverse events occurred in 15% of patients. Sensitivity for LMM detection by t-DNA and cytopathology was 84.6% (95% CI 54.6% to 98.1%) and 53.9% (95% CI 25.1% to 80.8%), respectively. Pre-therapy and on-therapy CSF cytokine analysis demonstrated complete responders clustered together.ConclusionsPembrolizumab conferred a 38% CNS response rate in patients with LMM, a tolerable safety profile, and deep responses in selected patients with ICI-responsive tumors. CSF t-DNA may be sensitive for LMM detection, and immunologic subsets of CNS response warrant further study.Trial registration numberNCT03091478

Double Blind Study

TPS5092 Background: ENZA is approved to treat men with CRPC. TALA is a poly(ADP-ribose) polymerase (PARP) inhibitor that inhibits PARP1/PARP2 and traps PARP on DNA, preventing DNA damage repair (DDR), and causing cell death in BRCA1/2-mutated cells. TALA is approved in the US to treat germline BRCA1/2-mutated HER2- locally advanced/metastatic breast cancer. A combination of TALA with ENZA in mCRPC may improve clinical outcomes. TALAPRO-2 (NCT03395197) is a 2-part study to evaluate the efficacy, safety, pharmacokinetics and (patient) pt-reported outcomes of the combination treatment. The focus here is on P2 of TALAPRO-2. Methods: Approximately 860 pts are planned to be enrolled in P2 from multinational sites. Pts are aged ≥18 years, have asymptomatic/mildly symptomatic mCRPC, Eastern Cooperative Oncology Group performance status ≤1, no brain metastases, and have not received taxanes/novel hormonal therapy (NHT). P2 is a randomized double-blind study that will evaluate safety, efficacy, and pt-reported outcomes of TALA (0.5 mg QD) + ENZA (160 mg QD) vs placebo + ENZA (160 mg QD). Pts will be randomized to 1 of 2 treatment groups: TALA + ENZA, or matching placebo + ENZA. Randomization will be stratified by prior treatment with NHT for castration-sensitive prostate cancer (CSPC) or prior treatment with taxane-based chemotherapy for CSPC (yes/no) and DDR mutation status (deficient vs. nondeficient/unknown). The primary endpoint is radiographic progression-free survival (rPFS), defined as time to progression in soft tissue per RECIST v1.1 or in bone per PCWG3 criteria or death. The key secondary endpoint is overall survival (OS). Efficacy will be assessed by radiography every 8 weeks up to week 25 and every 8-12 weeks thereafter. The analyses of rPFS will be compared between TALA in combination with ENZA and placebo in combination with ENZA by using a 1-sided stratified log-rank test. OS will be evaluated separately in the all comers and the DDR-deficient populations. Pt recruitment is ongoing. Results: n/a. Conclusions: n/a. Clinical trial information: NCT03395197.

Purpose PF-00562271 is a novel inhibitor of focal adhesion kinase (FAK). The objectives of this study were to identify the recommended phase II dose (RP2D) and assess safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and antitumor activity of PF-00562271. Patients and Methods Part 1 was a dose escalation without and with food. Part 2 enrolled specific tumor types in an expansion at the RP2D and also assessed the effect of PF-00562271 on single-dose midazolam PK in a subgroup of patients. Results Ninety-nine patients (median age, 60 years; 98% with Eastern Cooperative Oncology Group performance status of 0 or 1) were treated in 12 fasting and three fed cohorts. The 125-mg twice-per-day fed dose was deemed the maximum-tolerated dose (MTD) and RP2D. Grade 3 dose-limiting toxicities included headache, nausea/vomiting, dehydration, and edema. Nausea was the most frequently observed toxicity (60% of patients, all grades 1 or 2 at RP2D). PF-00562271 exposure increased with increasing dose; serum concentration–time profiles showed characteristic nonlinear disposition. Steady-state exposures were reached within 1 week. On coadministration, geometric mean values of midazolam maximal observed serum concentration and area under the serum concentration–time curve increased by 60% and more than two-fold, respectively. Of 14 patients evaluable by [18F]fluorodeoxyglucose positron emission tomography in the expansion cohorts, seven metabolic responses were observed. With conventional imaging, 31 patients had stable disease at first restaging scans, and 15 of these remained stable for six or more cycles. Conclusion The MTD and RP2D of PF-00562271 is 125 mg twice per day with food. PF-00562271 displayed time- and dose-dependent nonlinear PK and is likely a potent CYP 3A inhibitor. This first-in-class study supports further investigation of FAK as a promising therapeutic target.

A 53-year-old man presented with a 6-month history of mild hoarseness, with no associated pain, dysphagia, or stridor. At nasoendoscopy, a lesion was detected involving the whole length of the left vocal cord, with abnormal mucosa also seen in the right ventricle ( Fig 1 ). The left vocal cord movement was impaired. There were no palpable neck nodes. Biopsy under anesthesia revealed moderately differentiated squamous cell carcinoma. He was a current smoker of 30 cigarettes per day (45 pack-year smoking history), and he consumed four standard drinks of alcohol per day. His Eastern Cooperative Oncology Group performance status was 1, and he had no significant comorbidities. Radiologic review of his outside computed tomography scan noted that it was of poor quality, and a magnetic resonance imaging scan was recommended, which showed low-volume T4a disease based on focal thyroid cartilage penetration ( Fig 2 ). A positron emission tomography (PET) scan revealed no evidence of nodal or distant metastasis.

The prevalence of sarcopenia (p = 0.0003), age ≥ 75 years old (p = 0.03), and ECOG-PS 2–3 (p = 0.01) were significantly higher in the patients receiving BSC only. Logistic regression analysis demonstrated that SMI was the only independent associated factor identifying patients with LAPC who were treated with BSC only and not chemotherapy after adjusting for age and ECOG-PS. Conclusion Our study has shown that computed tomographic skeletal muscle analysis at the time of a diagnostic CT for patients with pancreatic cancer is feasible and can detect sarcopenia and malnourished patients who are much less likely to take up chemotherapy. These patients could be triaged to oncology assessment prior to EUS-B to avoid unnecessary investigations.
