Precision Medicine in Practice: Timely Use of Tumor NGS Remains Suboptimal in Common Cancers

RR

SUMMARY: Next-generation sequencing (NGS) has revolutionized the management of advanced cancers by enabling identification of tumor-specific genomic alterations for which targeted therapies are now available. National guidelines recommend early and routine NGS testing for patients with advanced or metastatic solid tumors to inform treatment decisions. In the United States, the five most prevalent advanced or metastatic solid tumors include advanced Non-Small Cell Lung Cancer (aNSCLC), metastatic Breast Cancer (mBC), metastatic Prostate Cancer (mPC), advanced Colorectal Cancer (aCRC), and metastatic Pancreatic Cancer (mPanC). For these malignancies, the integration of NGS has become increasingly critical in guiding targeted therapy selection and improving survival outcomes. Despite the approval of multiple targeted therapies for these malignancies, real-world utilization of NGS remains inconsistent.

In this study presented at the 2025 ASCO Annual Meeting, Chehade and colleagues,  evaluated patterns in NGS testing and its timing, relative to patient mortality.

Study Overview: This retrospective analysis leveraged the Flatiron Health EHR-derived de-identified database across 280 cancer clinics, spanning data from 2011 onward. The study included patients with a diagnosis of aNSCLC, mBC, mPC, aCRC, or mPanC, all of whom had records of NGS testing and a documented date of death. The researchers identified 86,536 patients with advanced non-small cell lung cancer, 36,000 with metastatic breast cancer, 35,702 with advanced colorectal cancer, 24,105 with metastatic prostate cancer and 14,964 with metastatic pancreatic cancer. About a third of patients from each cancer group received NGS testing (NSCLC, 36.3%; breast cancer, 32.1%; colorectal cancer, 41%; prostate cancer, 30.9%; and pancreatic cancer, 35.4%).

Patients were categorized based on the interval between receipt of NGS results and death:

  • More than 3 months before death
  • Within 3 months of death
  • After death

Key Findings Across cancer types, only 30% to 40% of patients received NGS testing. Among those who were tested and had a recorded date of death, the timing of NGS was as follows:

Timing of First NGS aNSCLC (N=19,958) mBC (N=5,689) mPC (N=3,397) aCRC (N=8,553) mPanC (N=3,957)
>3 mo before death          72.3%        81.6%        85.4%        85.0%         71.1%
Within 3 mo of death          25.6%        16.9%        13.5%        13.7%         26.5%
After death          2.1%        1.5%        1.1%        1.3%         2.4%

Notably, up to one in four patients with NSCLC or pancreatic cancer received their first NGS results within 3 months of death, a timeframe often too late for actionable therapeutic intervention.

Interpretation and Implications Despite advances in molecularly targeted therapies and growing guideline support for comprehensive genomic profiling, real-world testing patterns remain suboptimal:

  • Low uptake: Only about a third of eligible patients undergo NGS testing.
  • Late testing: A substantial proportion of tested patients receive results within 3 months of death.
  • Missed opportunities: Many patients are never tested—or are tested too late to benefit from life-extending therapies.

These findings highlight ongoing gaps in precision oncology implementation, especially in community-based settings.

Next Steps & Recommendations To improve the utility of NGS in oncology, efforts should focus on:

  • Earlier testing: At diagnosis or at first progression of advanced disease.
  • Workflow integration: Embedding NGS into routine clinical pathways.
  • Education: Raising awareness among clinicians and patients about the benefits of timely testing.
  • Health system support: Addressing barriers such as reimbursement, turnaround times, and tissue availability.

Conclusion: Real-World Data from this large retrospective analysis reveal late-stage testing and underutilization of life-prolonging genomic profiling. This study underscores an urgent need to optimize the timing and uptake of NGS testing in patients with advanced solid tumors. Earlier and broader testing is essential to ensure patients have access to the most effective, personalized treatment strategies, and to avoid the missed potential of life-extending therapies.

Subcutaneous administration overview

While immune checkpoint inhibitors have emerged as key treatment options for certain types of cancer, they are primarily delivered through intravenous (IV) administration,3 creating a need for alternative routes of administration.4-5 A subcutaneous (SC) injection may reduce the time preparing and administering treatment compared to IV delivery, offer practice flexibility that may free up infusion chairs, and deliver treatment faster.3,5 “Infusion centers are overwhelmed. Infusion chairs may open up if we transition to approved SC options,” remarked Dr George.

Evaluation of comparable PK, efficacy, and safety of SC OPDIVO Qvantig with IV nivolumab

OPDIVO Qvantig is formulated with hyaluronidase to increase the dispersion and absorption of SC nivolumab.1 CheckMate 67T, a randomized, open-label, phase 3 noninferiority trial, was designed to compare the PK, efficacy, and safety of OPDIVO Qvantig (delivered as a SC injection) with IV nivolumab.1,4

 OPDIVO QVANTIG, as monotherapy, is indicated for the first-line treatment of adult patients with intermediate- or poor-risk advanced renal cell carcinoma (RCC), following treatment with intravenous nivolumab and ipilimumab combination therapy. OPDIVO QVANTIG is not indicated in combination with ipilimumab for the treatment of renal cell carcinoma. Please see additional 16 indications below.

OPDIVO QVANTIG is associated with the following Warnings and Precautions: severe and fatal immune-mediated adverse reactions including pneumonitis, colitis, hepatitis and hepatotoxicity, endocrinopathies, nephritis with renal dysfunction, dermatologic adverse reactions, other immune-mediated adverse reactions; complications of allogeneic hematopoietic stem cell transplantation (HSCT); embryo-fetal toxicity; and increased mortality in patients with multiple myeloma when OPDIVO QVANTIG is added to a thalidomide analogue and dexamethasone, which is not recommended outside of controlled clinical trials.

Please see Important Safety Information for OPDIVO QVANTIG below and US Full Prescribing Information for OPDIVO QVANTIG.

CheckMate 67T was a phase 3, randomized (1:1), open-label, noninferiority trial evaluating OPDIVO Qvantig (1,200 mg of nivolumab and 20,000 units of hyaluronidase) compared to intravenous nivolumab, in adult patients with advanced or metastatic clear-cell renal cell carcinoma (ccRCC) who received prior systemic therapy.1,4 Patients were stratified by weight (<80 kg versus ≥80 kg) and International Metastatic RCC Database Consortium (IMDC) risk score (favorable vs intermediate vs poor risk).1 A total of 495 patients were randomized to receive either OPDIVO Qvantig every 4 weeks subcutaneously (n=248) or nivolumab 3 mg/kg every 2 weeks intravenously (n=247).1,4 The co-primary endpoints were time-averaged serum concentration over 28 days (Cavgd28) and minimum serum concentration at steady state (Cminss).4 The key powered secondary endpoint was overall response rate, as assessed by blinded independent central review. The minimum follow-up time was 8 months.4

Pharmacokinetic, efficacy, and safety results

CheckMate 67T demonstrated that the PK of OPDIVO Qvantig was noninferior to that of intravenously administered nivolumab.1,4*

 

OPDIVO Qvantig resulted in a safety profile comparable with IV nivolumab.1 Dr George noted, “Safety was similar between administration methods. Rates of adverse reactions were similar for IV and SC nivolumab administration.”6 Please see safety table below for more information.

Summary and conclusions

OPDIVO Qvantig resulted in comparable PK, efficacy, and safety to IV nivolumab and may be the right option for your eligible patients.1 This 3-5 minute SC injection option may reduce the steps required for preparation and time needed for administration compared to IV nivolumab.1,2* There is no need for IV preparation, dilution, weight-based dose calculations, or port access with OPDIVO Qvantig.1 According to Dr George, “For my appropriate patients, it gives me flexibility. It may save administration time.* For eligible patients, it’s great to have this subcutaneous treatment option.”

IMPORTANT SAFETY INFORMATION 

Severe and Fatal Immune-Mediated Adverse Reactions

  • Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO QVANTIG. Early identification and management are essential to ensure safe use of OPDIVO QVANTIG. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
  • Withhold or permanently discontinue OPDIVO QVANTIG depending on severity (please see Section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO QVANTIG interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over for at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.
  • Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

  • Immune-mediated hepatitis occurred in 2.4% (6/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (1.6%), and Grade 2 (0.8%) adverse reactions. Intravenous nivolumab in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to intravenous nivolumab alone. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. With the combination of intravenous nivolumab and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% (35/320) of patients. 

Immune-Mediated Endocrinopathies

  • OPDIVO QVANTIG can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO QVANTIG depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated.
  • Adrenal insufficiency occurred in 2% (5/247) of patients receiving OPDIVO QVANTIG, including Grade 3 (0.8%) and Grade 2 (1.2%) adverse Adrenal insufficiency occurred in 4.7% (15/320) of patients with RCC who received intravenous nivolumab with cabozantinib, including Grade 3 (2.2%) and Grade 2 (1.9%) adverse reactions. Hypophysitis occurred in 0.6% (12/1994) of patients treated with single agent intravenous nivolumab, including Grade 3 (0.2%) and Grade 2 (0.3%). Thyroiditis occurred in 0.4% (1/247) of patients receiving OPDIVO QVANTIG, including a Grade 1 (0.4%) adverse reaction.
  • Hyperthyroidism occurred in 0.8% (2/247) of patients receiving OPDIVO QVANTIG, including Grade 2 (0.4%) adverse reactions. Hypothyroidism occurred in 9% (23/247) of patients receiving OPDIVO QVANTIG, including Grade 2 (5.7%) adverse reactions.
  • Grade 3 diabetes occurred in 4% (1/247) of patients receiving OPDIVO QVANTIG.

  • OPDIVO QVANTIG can cause immune-mediated
  • Grade 2 immune-mediated nephritis and renal dysfunction occurred in 1.2% (3/247) of patients receiving OPDIVO QVANTIG.

Immune-Mediated Dermatologic Adverse Reactions

  • OPDIVO QVANTIG can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome, toxic epidermal necrolysis (TEN), and DRESS (drug rash with eosinophilia and systemic symptoms), has occurred with PD-1/PD-L1 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative Withhold or permanently discontinue OPDIVO QVANTIG depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information).
  • Immune-mediated rash occurred in 7% (17/247) of patients, including Grade 3 (0.8%) and Grade 2 (2.8%) adverse reactions.

Other Immune-Mediated Adverse Reactions

  • The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO QVANTIG or intravenous nivolumab as single agent or in combination with chemotherapy or immunotherapy, or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions: cardiac/vascular: myocarditis, pericarditis, vasculitis; nervous system: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur; gastrointestinal: pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis; musculoskeletal and connective tissue: myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica; endocrine: hypoparathyroidism; other (hematologic/immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.
  • Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation

  • Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO QVANTIG. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO QVANTIG and allogeneic HSCT.
  • Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO QVANTIG prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

  • Based on its mechanism of action and data from animal studies, OPDIVO QVANTIG can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of nivolumab to cynomolgus monkeys from the onset of organogenesis through delivery resulted in increased abortion and premature infant Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO QVANTIG and for 5 months after the last dose.

Increased Mortality in Patients with Multiple Myeloma when Nivolumab Is Added to a Thalidomide Analogue and Dexamethasone

  • In randomized clinical trials in patients with multiple myeloma, the addition of a PD-1 blocking antibody, including intravenous nivolumab, to a thalidomide analogue plus dexamethasone, a use for which no PD-1 or PD-L1 blocking antibody is indicated, resulted in increased Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Lactation

  • There are no data on the presence of nivolumab or hyaluronidase in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment and for 5 months after the last dose of OPDIVO Qvantig.

AI Tool SCORPIO Predicts Overall Survival in Patients Receiving Therapy with Immune Checkpoint Inhibitors

RR

SUMMARY: Immune checkpoint inhibitors (ICIs) have dramatically transformed the management and prognosis of various malignancies. By enhancing the ability of the immune system to identify and destroy cancer cells, ICIs have provided significant improvements in treatment outcomes across a range of tumor types.

Currently, Tumor Mutational Burden (TMB) and PD-L1 expression are the primary biomarkers approved by the FDA for predicting ICI efficacy. While these biomarkers have shown promise, they exhibit limited accuracy and face significant practical limitations, such as the need for sufficient tumor tissue for TMB analysis and the lack of standardized protocols for PD-L1 ImmunoHistoChemistry (IHC). These challenges underscore the need for a predictive model that is more accessible, cost-effective, and applicable across diverse healthcare settings.

Machine learning is a a branch of artificial intelligence that enables algorithms to learn from data, and identify key patterns and make predictions based on available clinical and biological data. SCORPIO is an AI-based model that was developed to address this clinical need, and provides an accurate and scalable tool for predicting patient responses to ICIs.

Study Design: The present study employed a machine learning approach to predict the efficacy of ICIs across a range of cancer types. By using routine blood tests as well as clinical characteristics, and utilizing data from diverse populations and cancer types, SCORPIO aimed to provide a broadly applicable predictive tool that could be used in real-world clinical settings to guide treatment decisions, with the goal of improving precision medicine. SCORPIO was developed and validated using retrospective data from multiple cohorts, including internal data from two major cancer centers (Memorial Sloan Kettering Cancer Center and Mount Sinai Health System, as well as data from 10 global Phase 3 clinical trials.

Participants: This study encompassed a total of 9,745 patients treated with ICIs across 21 different cancer types. The participants came from diverse backgrounds, including varying ethnicities, socioeconomic statuses, comorbidities, and health literacy levels, which added to the robustness of this model and real-world applicability. The study included data from patients at Memorial Sloan Kettering Cancer Center (2,000 patients), Mount Sinai Health System (1,159 patients), and global clinical trials (4,447 patients), representing the largest dataset in cancer immunotherapy to date.

Data Collection Methods: The SCORPIO model was trained using routine blood test results and basic clinical variables such as age, gender, cancer type, and prior treatments. The model was validated across multiple datasets to ensure that it could accurately predict both overall survival (OS) and Clinical Benefits (Response Rate and stable disease) for patients treated with ICIs. This study utilized machine learning algorithms to identify patterns in this data and make predictions about patient outcomes.

Analysis Techniques: Time-dependent Area Under the receiver operating characteristic Curve (AUC) was used to evaluate the predictive accuracy of SCORPIO for OS across different time points (6, 12, 18, 24, and 30 months). The performance of this model was compared to existing FDA-approved biomarkers, including TMB and PD-L1 immunostaining, to assess its superiority in predicting patient outcomes.

Results: The SCORPIO model demonstrated strong predictive performance in multiple cohorts. In internal testing, SCORPIO achieved median time-dependent AUC values of 0.763 and 0.759 for predicting OS at various time points, significantly outperforming TMB, which achieved AUC values of 0.503 and 0.543. SCORPIO also outperformed TMB for predicting clinical benefit, with AUCs of 0.714 and 0.641, compared to TMB’s 0.546 and 0.573. Additionally, SCORPIO was able to predict clinical outcomes more accurately than PD-L1 IHC. 
External validation using data from 10 global phase 3 clinical trials and a real-world cohort from Mount Sinai Health System further supported the predictive power of SCORPIO. Despite the heterogeneity in the Mount Sinai Health System cohort, performance of SCORPIO remained consistent, demonstrating its potential for broad applicability in different patient populations and healthcare settings. While SCORPIO performed consistently well for Overall Survival prediction, its ability to predict Clinical Benefit varied across cancer types and cohorts, indicating that while the model is reliable for survival prognosis, there may still be challenges in accurately predicting Response Rate or stable disease in some contexts.

Conclusion: The SCORPIO model represents a significant advancement in the field of cancer immunotherapy. By leveraging routine blood tests and basic clinical data, SCORPIO provides a highly accurate and accessible method for predicting patient response to ICIs, surpassing the performance of existing FDA-approved biomarkers like TMB and PD-L1 IHC. Its consistent performance across diverse patient populations and cancer types makes it a promising tool for precision oncology.

This model could revolutionize the way physicians identify patients who are most likely to benefit from ICIs, offering a cost-effective, scalable alternative to current biomarkers that rely on complex genomic and immunologic assays. The widespread use of SCORPIO in clinical practice could improve patient outcomes by guiding more personalized treatment decisions, especially in settings where resources for advanced biomarker testing are limited. Future studies will focus on further refining the model to enhance its ability to predict clinical benefit across all cancer types and patient cohorts.

FDA Highlights Importance of DPD Deficiency Discussions with Patients Prior to Capecitabine or Fluorouracil Treatment

RR

SUMMARY: It is estimated that about 3-8% of the Caucasian population have a partial DPD (DihydroPyrimidine Dehydrogenase) deficiency and 0.3% have a complete DPD deficiency. Asian and African populations may be at greater risk of DPD deficiency. More than 8,000 toxic reactions and 1,300 deaths each year are attributed to Fluorouracil and Capecitabine.

The FDA has issued an update regarding the labeling of Capecitabine and 5-FU to raise awareness about the risks linked to DPD deficiency. Healthcare providers are urged to familiarize themselves with these risks and ensure that patients are informed before treatment about the potential for severe and potentially life-threatening side effects associated with DPD deficiency. Providers are also encouraged to discuss DPD testing options with patients.

Fluoropyrimidines, which include both 5-FU and its prodrug Capecitabine, are chemotherapy drugs used to treat cancer. The enzyme DPD, encoded by the DPYD gene, is responsible for breaking down more than 80% of Fluorouracil in the body. In patients with specific genetic variants of the DPYD gene, known to cause a significant reduction or absence of DPD activity (referred to as complete DPD deficiency), there is an elevated risk of severe toxic reactions such as mucositis, diarrhea, neutropenia, and neurotoxicity, which can be fatal. Even patients with partial DPD activity (partial DPD deficiency) may face increased risks of these dangerous side effects.

As part of Project Renewal, the FDAs Oncology Center of Excellence has updated the product labels for both Capecitabine and Fluorouracil to include important information about DPD deficiency. This revision highlights the need for healthcare providers to discuss the possibility of DPD deficiency with patients prior to initiating treatment.

  • Capecitabine or 5-FU should not be recommended for use in patients known to have certain homozygous or compound heterozygous DPYD variants that result in complete DPD deficiency. No dose has been proven safe for patients with complete DPD deficiency.
  • There is insufficient data to recommend a specific dose in patients with partial DPD deficiency.
  • All healthcare providers should inform patients of the potential for serious and life-threatening adverse reactions due to DPD deficiency. Providers should discuss with their patient whether the patient should be tested for genetic variants that are associated with an increased risk of serious adverse reactions from the use of Capecitabine or 5-FU.
  • Providers should consider testing prior to initiating Capecitabine or Fluorouracil to reduce the risk of serious adverse reactions.
  • Providers should be aware of the signs and symptoms associated with adverse reactions due to DPD deficiency and advise patients to immediately contact their provider if these occur, including severe mucositis, diarrhea, neutropenia, and neurotoxicity.
  • Providers should withhold or permanently discontinue Capecitabine or 5-FU based on clinical assessment of the onset, duration, and severity of the observed adverse reactions in patients with evidence of acute early-onset or unusually severe reactions, which may indicate complete DPD deficiency.
  • Four DPYD variants have been associated with impaired DPD activity in White populations, and one variant has been associated with impaired activity in individuals of African ancestry.

The FDA approved Uridine Triacetate (VISTOGARD®) in 2015, for the emergency treatment of adult and pediatric patients, who had severe or life-threatening toxicities within 4 days of treatment, following an overdose of 5-FU or Capecitabine . Uridine Triacetate is a Pyrimidine analog and following oral administration is deacetylated by nonspecific esterases, yielding Uridine in the circulation. Uridine is a direct antagonist of 5-FU and competitively inhibits 5-FU from incorporating in normal tissues, thus reducing cell damage and cell death.
