TPS8653 Background: The 5-year progression free survival (PFS) rate of patients with metastatic, PD-L1 negative, non-small cell lung cancer (NSCLC) remains poor, ranging from approximately 2% to 10% with standard immunotherapy-based treatment regimens. Based on promising anti-tumor activity in the phase 1 CodeBreaK 101 study, with partial responses observed in 62% (8/13) of PD-L1 negative patients in the first-line setting, we hypothesize that sotorasib plus platinum doublet chemotherapy will demonstrate durable clinical response and improved outcomes in this population. CodeBreaK 202 (NCT05920356) is a global phase 3 randomized study evaluating the efficacy of sotorasib versus pembrolizumab in combination with platinum doublet chemotherapy as first-line treatment for metastatic or locally advanced, PD-L1 negative, KRAS G12C-mutated NSCLC. Methods: Patients will be randomized 1:1 to either sotorasib 960 mg once daily or pembrolizumab administered in combination with carboplatin and pemetrexed for 4 cycles, followed by maintenance treatment with sotorasib or pembrolizumab administered in combination with pemetrexed. Key eligibility criteria include treatment-naïve metastatic or locally advanced stage IIIB/C disease that is not amenable to definitive chemoradiation, PD-L1 <1% expression, presence of KRAS G12C mutation, non-squamous tumor histology, and absence of actionable genomic alterations such as EGFR mutations and ALK rearrangements. Patients with both treated and untreated brain metastases are eligible if clinically asymptomatic. The primary endpoint is PFS per RECIST v1.1 by blinded independent central review (BICR). Key secondary endpoints include overall survival and objective response rate. Exploratory endpoints include intra-cranial PFS per RANO-BM criteria. Approximately 750 patients are planned to be enrolled and recruitment began on November 18, 2023. Contact Amgen Medical Information for more information: medinfo@amgen.com .

TPS8657 Background: Most patients (pts) with advanced non-small cell lung cancer (NSCLC) will receive treatment with immunotherapy and develop tumor resistance. Several trials investigating combination therapy have not shown benefit over chemotherapy. Additional therapeutic options are needed. Complex clinical trials increase barriers to enrollment. Pragmatic trial designs may overcome challenges with accrual and representativeness in the appropriate setting. S1800A was a randomized phase II trial within Lung-MAP that showed a statistically significant improvement in overall survival (OS) with PR versus SOC for pts with advanced NSCLC who had tumor progression on prior chemotherapy and immunotherapy (JCO 2023). As a follow-on, we designed a pragmatic, randomized, registration intent trial to validate OS results and enhance representative accrual reflecting real-world practice. Methods: S2302 is a registration-intent randomized trial for pts who previously received PD-(L)1 inhibitor therapy for at least 84 days and platinum-based therapy, stratified by immediate prior line of therapy including PD-(L)1 inhibition (yes/no) and PS (0/1 v. 2). Pts are randomized to PR or investigator’s choice SOC (recommended to be based on NCCN guidelines). The primary objective is to compare OS between the arms. The only secondary objective is to summarize serious and unexpected high-grade (Grade 3-4) treatment-related adverse events and all Grade 5 adverse events. The accrual goal is 700 pts based on a design with 85% power to detect a hazard ratio of 0.77, using a 1-sided 2.5% level log-rank test. Estimated accrual duration is 24 months. As of January 2024, 286 pts were randomized, and enrollment is ongoing. S2302 Pragmatica-Lung presents a novel and potentially practice-changing paradigm to conduct a study with a combination of FDA approved drugs with well-known safety profiles and limited toxicity overlap. There are no onerous radiology or specimen requirements, and SOC treatment is provided as per FDA-approved package inserts and institutional policies. The goal is to empower practicing clinicians to enroll pts they see every day by reducing the study barriers and burden of clinical trial participation. The resulting pts enrolled will be more representative than other registration-intent trials. This approach allows the trial to reach more patients and holds the potential to better inform the field across a more representative set of pts with broader impact.

TPS9601 Background: Immune checkpoint inhibitors (ICI) improved outcomes of patients (pts) with advanced melanoma. Nevertheless, a significant number have immune-mediated adverse event (iAE). Due to the impact on quality of life and other therapeutic options, early identification of pts with increased risk of iAE is needed. CD8 immuno-PET with [89Zr] crefmirlimab berdoxam (Zr-Df-IAB22M2C) has shown to be a specific tool to visualize CD8+ T cells mediating both anti-tumor immune response and inflammatory adverse effects rendering this an innovative evaluation method in the field of immuno-oncology. Methods: Trial design: Open-label, single-arm, single center study to determine if CD8+ T-cell infiltration evaluated by immune-PET provides diagnostic gain in early detection of severe iAE. Pts with irresectable stage III/IV melanoma receiving nivolumab + ipilimumab (NIVO+IPI) may be included. Primary objective: Feasibility of early detection of iAE by semiquantitative assessment of CD8+ T-cell infiltration using immune-PET. Secondary objectives: 1) Prediction of iAE using immuno-PET for semiquantitative assessment of CD8+ T-cell infiltration; 2) Correlation between CD8+ T-cell infiltration in metastasis and lymphoid organs and response. Baseline Imaging. To assess glucose metabolism in metastases, primary and secondary lymphatic organs [18F] FDG PET/CT (60 min p.i. 1.5 MBq/KG/BW) is performed on a high sensitivity PET/CT with large field of view (Siemens Vision Quadra). Immediately after PET/CT data acquisition, pts are injected with [89Zr] crefmirlimab berdoxam (37 MBq ±20%) and undergo immuno-PET/CT 24 hours p.i. to detect CD8+ T-cells in metastases and lymphoid organs. NIVO+IPI is administered immediately after completion of [89Zr] crefmirlimab berdoxam-PET/CT. Blood samples are taken for immune cell composition analysis, activation state, proteomic investigation (cytokine/chemokines) as well as metabolic profile. Therapy Phase Imaging: Three weeks after first ICI cycle and before second cycle, follow-up PET/CT are performed with both radiotracers [18F]FDG and [89Zr] crefmirlimab berdoxam following the identical protocol described above.

Published: June 2024

TPS9603 Background: Melanoma brain metastases (MBM) are a leading cause of morbidity and mortality for patients with advanced melanoma. Modern systemic therapies are insufficient at controlling MBM, resulting in median overall survival (OS) of <1 year. Adoptive T cell therapy, using tumor infiltrating lymphocytes (TIL), has demonstrated efficacy in treating advanced melanoma. Lifileucel (LN-144), an autologous TIL product, was recently shown to be safe and effective for patients with PD-1 refractory melanoma. However, no trials have yet explored lifileucel in patients with active MBM. Methods: This single-center pilot trial (NCT05640193) aims to enroll 10 pts with asymptomatic MBM from non-uveal melanoma to receive lifileucel. Patients must have ≥1 intracranial lesion measuring 5-30mm visible on MRI to be used as a target lesion for modified (m)RECIST measurement, progression on prior anti-PD-1 therapy (with or without anti-CTLA-4), progression on targeted therapy (if BRAF V600E/K-mutated), ECOG PS ≤1, ≥1 resectable lesion(s) (≥1.5 cm), recovered from prior surgery/anticancer treatment-related AEs (grade ≤1). Patients are ineligible if they have symptomatic MBM and/or require corticosteroids of ≥10 mg/day of prednisone or equivalent. Lifileucel is generated from resected tumor in a centralized GMP process. The regimen includes nonmyeloablative lymphodepletion with cyclophosphamide 750 mg/m2 on days 1-3 and fludarabine 30 mg/kg on days 1-4 (reduced dose compared with standard lifileucel protocol), lifileucel infusion, and up to 6 doses of high-dose IL-2. The primary endpoint is feasibility, defined as ≥7/10 patients who undergo tumor resection successfully receiving lifileucel infusion. Secondary endpoints are safety, feasibility of manufacturing lifileucel in patients with MBM, and brain metastasis response rate (BMRR) per mRECIST 1.1. Exploratory endpoints include overall objective response rate by mRECIST 1.1, best extracranial response rate, intracranial progression-free survival (PFS), overall PFS, OS. Extensive correlative analyses of peripheral blood mononuclear cells, plasma, tumors, and cerebrospinal fluid are planned to better understand MBM growth, treatment resistance, and response of the central nervous system to lifileucel.

TPS9607 Background: A significant portion of patients (pts) with advanced MEL develop resistance to immune checkpoint inhibitors (ICI). The gut microbiome is a major tumor-extrinsic regulator of ICI response. In mice, gut microbiota modulate therapeutic activity of ICI, and administration of certain gut commensals or responder-derived fecal microbiota transplantation (R-FMT) promotes anti-PD-1 efficacy in melanoma-bearing mice. In the LEAP-004 trial, P+L produced 21% ORR in PD-1 R/R MEL with Gr3+ TRAE 45.6%. Longitudinal analyses of gut microbiome samples from ICI-treated cancer pts suggests key species including Actinobacteria and Firmicutes are associated with favorable response. We and others have previously demonstrated that microbiome modulation using R-FMT reversed PD-1 non-response in PD-1 R/R MEL. In PD-1 naïve MEL, healthy donor FMT (hdFMT) augments benefit of PD-1 monotherapy. We hypothesized that intestinal dysbiosis mediates PD-1 resistance in PD-1 R/R MEL, microbiome modulation may reverse TKI toxicity, and that R-FMT may resensitize MEL to PD-1 blockade. Methods: This is an investigator-initiated, randomized, phase II trial of P+L vs. P+L+R-FMT in PD-1 R/R MEL. Pts must have measurable disease per RECIST v1.1, no active CNS metastases (or if present, previously treated and stable on repeat imaging), and no contraindications to FMT administration. R-FMT is derived from non-obese, advanced MEL with durable response (mPFS ≥24 months) following prior PD-1 ICI, with no recent (≤1 month) antibiotic exposure. Donors are screened broadly for infectious agents including SARS-CoV-2 using bookend screening. R-FMT is processed to make fecal infusates and orally bioavailable capsules. Eligible pts are randomized 1:1 to either P+L [P 200mg every 3 weeks (Q3W) along with L 20mg orally once daily] or P+L+R-FMT. R-FMT is administered endoscopically on D1, and D42, and thereafter via capsules until progression or unacceptable toxicity. Response is assessed at D73, and thereafter Q12W. Pts undergo biopsies at baseline and W8, with optional biopsy at progression. Primary endpoint: ORR assessed using RECIST v1.1 by Blinded Independent Central Review (BICR). Secondary endpoints include: safety, progression-free survival (PFS), overall survival (OS), and landmark PFS/OS. Key translational endpoints include immune activation (tumor tissue, blood), metagenomic engraftment, and transcriptomic analyses of intestinal luminal myeloid cells and exfoliome. The null hypothesis that the true ORR is 20% will be tested versus a one-sided alternative hypothesis of ≥50%. This design has a type I error rate 0.10 and power 0.8 when the true response rate is 0.25. Enrollment has commenced. Clinical trial information: NCT06030037 .

TPS9608 Background: Metastatic melanoma (MM) patients who have progressed following immune checkpoint inhibitors (ICI; anti–PD-1/CTLA-4 therapy) and targeted agents (BRAF/MEK inhibitors) have limited treatment options and dismal prognosis. An autologous tumor-infiltrating lymphocytes (TIL) therapy (LN-144, lifileucel) has demonstrated efficacy and durable responses in heavily pretreated advanced melanoma. In a phase II study of TIL therapy (lifileucel) with traditional lymphodepletion (LD), using fludarabine 25 mg/m2 for 5 days and cyclophosphamide (Cy) 60 mg/kg for 2 days, in 153 MM patients previously treated with ICI and BRAF/MEK inhibitors, an overall response rate (ORR) of 31% was noted, and the median duration of response (DOR) was not reached after 27.6 month follow up. We hypothesize that a reduced dose of Flu/Cy LD for TIL therapy will have similar TIL expansion and persistence post-infusion, resulting in similar efficacy with a reduced toxicity profile. Methods: Study NCT06151847 is a single-center, open-label phase II pilot trial evaluating the efficacy, in vivo persistence, and safety of TIL therapy after reduced dose Flu/Cy LD. Key inclusion criteria include unresectable or metastatic melanoma (stage IIIC-IV) with disease progression after one or more lines of therapy. Four of the 12 planned patients have been enrolled as of February 2, 2024. Central TIL manufacturing from at least a 1.5 cm tumor specimen involves ex vivo expansion through cell culture in the presence of the interleukin (IL)-2 and an anti-CD3 monoclonal antibody (1-150 x109 viable cells). Patients will receive an outpatient reduced-dose Flu/Cy LD regimen of Flu (30 mg/m2 on days -4, -3, -2, -1) and Cy (750 mg/m2 on days -4, -3, -2). Infusion of TIL will be performed on day 0 followed by high-dose IL-2 (600,000 IU/kg up to 6 doses). The primary objective will be to ascertain TIL persistence using T-cell receptor (TCR) sequencing at day 42 which will be compared to historical data already generated utilizing traditional Flu/Cy LD. The secondary objectives will be to evaluate the efficacy parameters including ORR, DOR, progression-free survival (PFS), and overall survival (OS), and the safety profile of TIL in combination with a reduced dose Flu/Cy LD regimen. Exploratory objectives will involvecorrelative analyses to characterize the immunome and microenvironment. If TIL persistence is roughly equivocal between the reduced and high-dose Flu/Cy LD regimens, the design of a larger-scale trial using reduced-dose Flu/Cy LD for TIL therapy may be considered. Study follow-up will continue for one year. Clinical trial information: NCT06151847 .

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. We report 4-year results of the phase II randomized AtezoTRIBE study. Eligible patients with metastatic colorectal cancer (mCRC) received first-line fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI)/bevacizumab (control group, n = 73) or FOLFOXIRI/bevacizumab plus atezolizumab (experimental group, n = 145). We present overall survival (OS) and updated outcomes according to tumor immune-related biomarkers, both in the intention-to-treat (ITT) population and the cohort of patients with proficient mismatch repair (pMMR) tumors. Median follow-up was 45.2 months (IQR, 42.6-49.2). In the ITT population, median OS was 33.0 and 27.2 months for experimental and control groups, respectively (hazard ratio [HR], 0.78 [80% CI, 0.61 to 0.98]; P = .084). An interaction effect between Immunoscore Immune-Checkpoint (IC) and treatment arm was observed ( Pint, .089), with higher benefit from atezolizumab in the Immunoscore IC-high group. In the pMMR cohort (N = 202), median OS was 30.8 and 29.2 months for experimental and control groups, respectively (HR, 0.80 [80% CI, 0.63 to 1.02]; P = .117). Interactions between treatment group and tumor mutational burden (TMB) and Immunoscore IC were reported ( Pint, .043 and .092, respectively), with patients bearing TMB-high and Immunoscore IC-high tumors deriving higher benefit from the addition of atezolizumab. First-line FOLFOXIRI/bevacizumab plus atezolizumab improves OS in patients with mCRC. In the pMMR group, patients with Immunoscore IC-high and/or TMB-high tumors are identified as a subgroup of interest to further develop this treatment.
Economic Analysis of On-Street Parking with Urban Delivery
Authors: Xu Zhengtian , Sun Xiaotong 
Published: June 2024

The surge in online shopping has dramatically increased the demand for short-term curb access for package pickups and deliveries, leading to heightened competition for limited curb space. This paper addresses the problem of how the unique parking demand of deliverers, particularly their parking duration for delivery attempts linked to parking space availability, affects the dynamics of urban curb parking systems. We develop continuum models of a curb parking system and perform analytical analyses to understand the dynamics and steady-state properties of the system under the influence of increased urban deliveries. We conduct comparative statics to examine how various curb management measures, such as pricing, parking duration caps, and dedicated delivery bays, influence the equilibrium conditions, followed by comparisons of the theoretical capacity of these measures. We further demonstrate the working mechanism of delivery bays and their role in forestalling specific failures within a hybrid system with both general parkers and deliverers. Finally, we investigate curb management strategies in nonstationary operational contexts and prescribe the optimal strategies therein. Our findings offer valuable insights into the unique properties that deliverers introduce to curb parking dynamics, highlighting the need for a strategic reevaluation of current management practices. We find that pricing strategies for metered parking to general parkers prove to be more efficient and flexible compared with other interventions. Notably, our analysis suggests that when curb parking pricing is optimally calibrated, the necessity for dedicated delivery bays diminishes. Furthermore, we reveal that optimal curb management strategies could diverge in response to surges in demand, depending on whether the increase sources from general parkers or deliverers. To be effective, the sizing of delivery bays must align with the underlying causes of parking scarcity.

Topology optimization of blazed gratings under conical incidence
Authors: Ans Simon , Zamkotsian Frédéric , Demésy Guillaume 
Published: June 2024

A topology optimization method is presented and applied to a blazed diffraction grating in reflection under conical incidence. This type of grating is meant to disperse the incident light on one particular diffraction order, and this property is fundamental in spectroscopy. Conventionally, a blazed metallic grating is made of a sawtooth profile designed to work with the ±1st diffraction order in reflection. In this paper, we question this intuitive triangular pattern and look for optimal opto-geometric characteristics using topology optimization based on finite element modelling of Maxwell’s equations. In practical contexts, the grating geometry is mono-periodic, but it is enlightened by a 3D plane wave with a wave vector outside of the plane of invariance. Consequently, this study deals with the resolution of direct and inverse problems using the finite element method in this intermediate state between 2D and 3D: the so-called conical incidence. A multi-wavelength objective is used in order to obtain a broadband blazed effect. Finally, several numerical experiments are detailed. Our numerical results show that it is possible to reach a 98% diffraction efficiency on the −1st diffraction order if the optimization is performed on a single wavelength, and that the reflection integrated over the [400,1500] nm wavelength range can be 29% higher in absolute terms, 56% in relative terms, than that of the sawtooth blazed grating when using a multi-wavelength optimization criterion (from 52% to 81%).
