Additionally, WGS can identify unique SVs that may be missed by conventional methods and enables clinical benefits such as HLA typing for potential transplant (alloHCT) or diagnostic refinement by retroviral insertion (e.g. HTLV-1). These findings demonstrate the potential for integration of WGS into clinical practice to enhance personalized treatment strategies.

"This study aimed to predict patient outcomes to immune checkpoint inhibitors (ICI) by developing an integrated DNA/RNA ICI biomarker. A de-identified pan-cancer cohort from the Tempus multimodal real-world database was utilized to develop and validate the Immune Profile Score (IPS) algorithm that leverages Tempus xT (DNA sequencing) and xR (RNA sequencing). The researchers found that IPS status can be used to stratify patient cohorts and prognosticate ICI-treatment response....The team analyzed real-world imaging patterns from a cohort of 4,147 advanced cancer patients treated with immune checkpoint inhibitors (ICI) across five solid tumor types....Incorporating these patterns into a microsimulation model, the team demonstrated that using the molecular biomarker in conjunction with CT imaging provided substantial cost savings and reduced inappropriate therapy compared to imaging alone, with the most benefit observed in small cell lung cancer (SCLC) treated with ICI-chemotherapy."

In this large, real-world translational research cohort of pts with HR+ MBC, low-level AURKA copy number gain was common. These data report the first evidence suggesting that low-level amplifications in AURKA, which conventional sequencing platforms miss, can provoke meaningful changes in gene expression as assessed via RNA transcriptome analysis. Further, low-level AURKA amplifications predict inferior outcomes on CDK4/6i for pts with HR+ MBC.

Ethics Approval Tempus AI, Inc. has been granted an IRB exemption (Advarra Pro00072742) permitting the use of de-identified clinical, molecular, and multimodal data in order to derive or capture results, insights, or discoveries.Download figure Open in new tab Download powerpoint Abstract 188 Figure 1

Background NDI-101150, an oral, selective, small molecule inhibitor of HPK1, is being studied as monotherapy and in combination with pembrolizumab. Ethics Approval This multicenter study was approved by the relevant Ethics Board at each study site. All participants gave informed consent before taking part.

Given updated diagnosis, definitive concurrent chemoradiation (CRT, 7000 cGy in 35 fractions) with weekly cisplatin was administered...NUT IHC staining was negative, as has been reported due to tissue fixation. With inconsistent diagnostic tools for an already rare malignancy, our case highlights the role early NGS can play in diagnosis of unique cases that can alter management.

"Tempus AI, Inc...today announced the launch of a new program specifically geared towards using algorithms to surface patients who are more likely to test positive for actionable biomarkers, and who should receive confirmatory testing in accordance with clinical guidelines. This program is part of the larger Tempus Next platform, which is designed to identify care gaps and equip clinicians with actionable insights at the point of care. The new Next program is now available and initially focused on the identification of care gaps associated with the human epidermal growth factor receptor 2 (HER2) testing recommended under clinical guidelines for patients with select metastatic cancers....As part of the initial launch, Tempus has built an algorithm that runs as part of xR, the company’s RNA sequencing assay, to help surface patients who are particularly likely to benefit from on-guideline immunohistochemistry (IHC) testing."

"Overall, these data suggest that MSI/dMMR CRC harboring RAS mutations are less immunogenic and appear to contain a lower tumor inflammatory profile of TIME than RASwt or BRAF V600E mutated tumors. Further analysis and validation are needed to confirm our data."

"In this retrospective analysis, Tempus EHR integrations increased ordering of comprehensive NSCLC NGS by 53%. Despite study limitations such as the incomplete resolution into internal alternate sequencing workflows, this large-scale analysis provides further evidence that EHR-based workflow improvements reduce the barrier to appropriate sequencing."

"In this large, real-world cohort of pts with metastatic NSCLC, DDRmt was associated with distinct TIME patterns including high TMB, MSI-H, and modest changes in immune cell infiltrates. These findings warrant further studies to understand how DDR pathway alterations mediate changes in the TIME to inform novel combinatorial immunotherapeutic approaches in NSCLC. >1Median (IQR)."

LUSC MAGE-A4HIGH tumors had a differentiated TiME profile. Our findings are consistent with an INFLAMLOWVASCLOW phenotype possibly indicative of an "immune desert" [Desbois et al 2020]. In contrast, LUAD MAGE-A4HIGH tumors had an INFLAMHIGHVASCLOW phenotype indicating that MAGE-A4 associations with TiME may be histology dependent in NSCLC.

This work revealed the presence of multiple SPs - characterized by distinct clinical and molecular traits. Further work will be able to contextualize STT response data using SPs to facilitate STT biomarker discovery.

In this post-hoc analysis study, we examine whether the PurIST subtypes can distinguish patients likely to respond to FOLFIRINOX (FFX) versus Gemcitabine + nab-paclitaxel (GnP). A cohort of de-identified PDAC patients was selected from the Tempus Oncology Database following an IRB-approved protocol... In this real-world cohort of advanced PDAC patients, we showed that classical patients with low ECOG scores had superior OS with 1L FFX treatment compared to 1L GnP. These findings demonstrate the potential for PurIST to aid in optimal treatment selection for patients with advanced PDAC.

This is the largest known data set exploring the genomic and immune landscape of BTC with ARID1A, PBRM1 and BAP1 alterations. Macrophages were the dominant immune cell TME and may be a target of interest. Co-alteration profile is distinct between ARID1A- vs PBRM1- and/or BAP1-altered BTC.

Analysis of this resource – encompassing a diverse collection of cancer types, HLA genotypes, and mutational/viral contexts – revealed a subset of TCRs enriched with allele-specific neo-antigens. This dataset is a valuable resource for TCR therapeutic discovery, and can help identify naturally occuring TCRs that may minimize on-target, off-tumor toxicity.

"Tempus...introduces its standalone RNA next-generation sequencing assay, Tempus xR. xR is a whole transcriptome panel for solid tumors, reporting clinically relevant fusions for more than 100 targeted genes, as well as altered splicing for MET Exon 14 and EGFRvIII."
