[PMID: 39059398 DOI: 10.1016/s2213-2600(24)00171-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 05/20/2024] [Accepted: 05/21/2024] [Indexed: 07/28/2024]
Abstract
BACKGROUND Currently approved targeted treatment for ROS1-rearranged non-small-cell lung cancer (NSCLC) has either inadequate intracranial activity or CNS-related toxicities. We evaluated the efficacy and safety of foritinib, a novel ALK and ROS1 inhibitor, in patients with advanced ROS1-rearranged NSCLC. METHODS This two-part (phase 2a and 2b), multicentre, single-arm, open-label, phase 2 study was done in 29 centres in China. Eligible participants were adults (aged ≥18 years) with histologically or cytologically confirmed ROS1-rearranged, locally advanced or metastatic stage IIIB-IV NSCLC, with an Eastern Cooperative Oncology Group performance status of 2 or less. Patients who had previously received no or one ROS1 inhibitor were enrolled into phase 2a, and patients who were naive to ROS1 inhibitor therapy were enrolled into phase 2b cohort 1. Participants in phase 2a received 80, 120, 160, or 210 mg foritinib succinate (foritinib) orally once daily over 21-day cycles; patients in phase 2b received the recommended phase 2 dose of 160 mg. The primary endpoint was objective response rate, assessed by the independent review committee in the full analysis set (ie, all participants who received at least one dose of study treatment). The safety analysis set included all participants who received at least one dose of study treatment and had available safety assessments. This study is ongoing and is registered with ClinicalTrials.gov, NCT04237805. FINDINGS Between March 26, 2020, and Dec 29, 2022, 104 patients were enrolled and treated. Six patients who had previously received more than one ROS1 inhibitor were enrolled in phase 2a before a protocol amendment stating that patients in this phase should have received no more than one ROS1 inhibitor; these patients were included in the safety analysis but excluded from the efficacy analysis of the ROS1-inhibitor-pretreated cohort. Therefore, the efficacy analysis set (n=98) included 42 patients from phase 2a (17 who were ROS1 inhibitor naive and 25 who had previously received ROS1 inhibitor) and 56 patients from phase 2b cohort 1. In phase 2a, the objective response rate was 94% (95% CI 71-100; 16 of 17 patients) in patients who were ROS1 inhibitor naive and 40% (21-61; ten of 25) in patients who had previously received ROS1 inhibitor. In phase 2b cohort 1, the objective response rate was 88% (95% CI 76-95; 49 of 56 patients). In a prespecified exploratory analysis in 41 patients with CNS metastases at baseline, the objective response rate was 100% (95% CI 48-100; five of five patients) in patients in phase 2a who were ROS1 inhibitor naive, 40% (16-68; six of 15) in patients in phase 2a who had previously received ROS1 inhibitor, and 90% (70-99; 19 of 21) in patients in phase 2b cohort 1. Grade 3-4 treatment-related adverse events occurred in 33 (32%) of 104 patients; the most common were hyperglycaemia (12 [12%] patients) and electrocardiogram prolonged QT interval (six [6%]). Serious treatment-related adverse events occurred in 11 (11%) patients, with hyperglycaemia (six [6%]) being most common. No treatment-related adverse events led to death. INTERPRETATION Foritinib showed systemic and intracranial antitumour activity and good tolerability in ROS1-inhibitor-naive patients with ROS1-rearranged NSCLC. Foritinib represents a promising treatment for these patients, especially in those with CNS metastases.

Abstract
On November 15, 2023, the U.S. Food and Drug Administration (FDA) granted traditional approval to repotrectinib (Augtyro, Bristol Myers Squibb Corporation) for the treatment of adult patients with locally advanced or metastatic receptor tyrosine kinase encoded by the ROS1 gene (ROS1)-positive non-small cell lung cancer (NSCLC). The approval was based on TRIDENT-1, a single-arm trial with multiple cohorts of patients with ROS1 fusion-positive (hereafter "ROS1-positive") NSCLC (NCT03093116), who were either treatment naïve or had received prior ROS1 tyrosine kinase inhibitor (TKI) and/or platinum-based chemotherapy. The primary efficacy outcome measure is objective response rate (ORR) assessed by blinded independent central review (BICR) using response evaluation criteria in solid tumors version 1.1. ORR was assessed in 71 patients who were ROS1 TKI naïve and 56 patients who had received a prior ROS1 TKI. Among the 71 patients who were ROS1 TKI naïve, the ORR was 79% (95% CI, 68-88), median duration of response was 34.1 months (95% CI, 26-NE). In patients who had received a prior ROS1 TKI and no prior chemotherapy, the ORR was 38% (95% CI, 25-52). The median duration of response was 14.8 months (95% CI, 7.6-NE); BICR-assessed responses were observed in CNS metastases in patients in both cohorts and in patients who developed resistance mutations following prior TKI therapy. The most common (>20%) adverse reactions were dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, ataxia, fatigue, cognitive disorders, and muscular weakness. A unique feature of this ROS1 TKI approval is the inclusion of robust evidence of efficacy in patients with ROS1-positive NSCLC who had progressed on prior ROS1 TKIs.

Abstract
Immune checkpoint inhibitors (ICIs) are an approved therapy for the management of various advanced neoplasms. Limited reviews focus on the influence of this therapy resulting in pancreatitis. This review discusses the relationship between ICIs and their effects on the pancreas, including the incidence of pancreatitis, immunotherapy, programmed cell death 1 (PD-1) receptors, driver mutations, programmed death ligand 1 (PD-L1), and immune-related adverse events. Additionally, it focuses on the clinical presentations, diagnosis, case studies, and mechanisms by which ICIs activate different pathways to cause pancreatitis. We conducted a comprehensive literature search using PubMed, Cochrane Library, and Google Scholar databases to identify relevant studies on ICI-associated pancreatitis. The review explores the incidence and epidemiology of ICI-induced pancreatitis, its clinical presentation, diagnostic criteria, and management strategies.The overall incidence of ICI-induced pancreatitis is estimated at 1-2%, with higher rates observed in combination therapy. Clinical presentations range from asymptomatic enzyme elevations to severe pancreatitis. Diagnosis relies on a combination of clinical symptoms, elevated pancreatic enzymes, and imaging findings, with MRI and endoscopic ultrasound showing promise in early detection. Management strategies include IV fluid administration, pain control, and nutritional support. The efficacy of corticosteroids remains controversial, and alternative immunosuppressants are being explored for steroid-refractory cases. Long-term monitoring is crucial due to the risk of chronic pancreatitis and pancreatic insufficiency. This review highlights the need for further research to elucidate the exact mechanisms of ICI-associated pancreatic injury, develop predictive biomarkers, and refine treatment protocols. As ICI use continues to expand, a thorough understanding of this adverse event is essential for optimizing patient care and outcomes in cancer immunotherapy.

Abstract
Despite ROS1 fusion-positive NSCLC accounting for approximately 1% to 2% of NSCLC, there is a long list of ROS1 tyrosine kinase inhibitors (TKIs) being developed in addition to three approved ROS1 TKIs, crizotinib, entrectinib and repotrectinib. Here, we categorized ROS1 TKIs by their structures (cyclic versus noncyclic) and inhibitory abilities (active against solvent front mutation G2032R or central β-sheet #6 [Cβ6] mutation L2086F) and summarized their reported clinical activity in order to provide a dashboard on how to use these ROS1 TKIs in various clinical situations. In addition, the less known Cβ6 mutation ROS1 L2086F confer resistances to next-generation ROS1 TKIs (repotrectinib, taletrectinib, and potentially NVL-520) that can be overcome by cabozantinib as documented in published patient reports and potentially by certain L-shaped type I ROS1 TKIs including ceritinib and gilteritinib, which is approved as a FLT3 inhibitor for relapsed refractory FLT3+ acute myeloid leukemia but have published preclinical activites against ROS1 (and ALK). Future clinical trials should investigate cabozantinib and gilteritinib to repurpose them as ROS1 TKIs that can target ROS1 L2086F Cβ6 mutation.

Clinical Benefit from Docetaxel +/- Ramucirumab Is Not Associated with Mutation Status in Metastatic Non-Small-Cell Lung Cancer Patients Who Progressed on Platinum Doublets and Immunotherapy. Cancers (Basel) 2024; 16:935. [PMID: 38473297 PMCID: PMC10931294 DOI: 10.3390/cancers16050935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/07/2024] [Accepted: 02/21/2024] [Indexed: 03/14/2024] Open
Abstract
Docetaxel +/- ramucirumab remains the standard-of-care therapy for patients with metastatic non-small-cell lung cancer (NSCLC) after progression on platinum doublets and immune checkpoint inhibitors (ICIs). The aim of our study was to investigate whether the cancer gene mutation status was associated with clinical benefits from docetaxel +/- ramucirumab. We also investigated whether platinum/taxane-based regimens offered a better clinical benefit in this patient population. A total of 454 patients were analyzed (docetaxel +/- ramucirumab n=381; platinum/taxane-based regimens n=73). Progression-free survival (PFS) and overall survival (OS) were compared among different subpopulations with different cancer gene mutations and between patients who received docetaxel +/- ramucirumab versus platinum/taxane-based regimens. Among patients who received docetaxel +/- ramucirumab, the top mutated cancer genes included TP53 (n=167), KRAS (n=127), EGFR (n=65), STK11 (n=32), ERBB2 (HER2) (n=26), etc. None of these cancer gene mutations or PD-L1 expression was associated with PFS or OS. Platinum/taxane-based regimens were associated with a significantly longer mQS (13.00 m, 95% Cl: 11.20-14.80 m versus 8.40 m, 95% Cl: 7.12-9.68 m, LogRank P=0.019) than docetaxel +/- ramcirumab. Key prognostic factors including age, histology, and performance status were not different between these two groups. In conclusion, in patients with metastatic NSCLC who have progressed on platinum doublets and ICIs, the clinical benefit from docetaxel +/- ramucirumab is not associated with the cancer gene mutation status. Platinum/taxane-based regimens may offer a superior clinical benefit over docetaxel +/- ramucirumab in this patient population.

Abstract
Neurotrophic tyrosine receptor kinase (NTRK) has been a remarkable therapeutic target for treating different malignancies, playing an essential role in oncogenic signaling pathways. Groundbreaking trials like NAVIGATE led to the approval of NTRK inhibitors by the Food and Drug Administration (FDA) to treat different malignancies, significantly impacting current oncology treatment. Accurate detection of NTRK gene fusion becomes very important for possible targeted therapy. Various methods to detect NTRK gene fusion have been applied widely based on sensitivity, specificity, and accessibility. The utility of different tests in clinical practice is discussed in this study by providing insights into their effectiveness in targeting patients who may benefit from therapy. Widespread use of NTRK inhibitors in different malignancies could remain limited due to resistance mechanisms that cause challenges to medication efficacy in addition to common side effects of the medications. This review provides a succinct overview of the application of NTRK inhibitors in various types of cancer by emphasizing the critical clinical significance of NTRK fusion gene detection. The discussion also provides a solid foundation for understanding the current challenges and potential changes for improving the efficacy of NTRK inhibitor therapy to treat different malignancies.

Dailah HG, Hommdi AA, Koriri MD, Algathlan EM, Mohan S. Potential role of immunotherapy and targeted therapy in the treatment of cancer: A contemporary nursing practice. Heliyon 2024; 10:e24559. [PMID: 38298714 PMCID: PMC10828696 DOI: 10.1016/j.heliyon.2024.e24559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Revised: 01/09/2024] [Accepted: 01/10/2024] [Indexed: 02/02/2024] Open
Abstract
Immunotherapy and targeted therapy have emerged as promising therapeutic options for cancer patients. Immunotherapies induce a host immune response that mediates long-lived tumor destruction, while targeted therapies suppress molecular mechanisms that are important for tumor maintenance and growth. In addition, cytotoxic agents and targeted therapies regulate immune responses, which increases the chances that these therapeutic approaches may be efficiently combined with immunotherapy to ameliorate clinical outcomes. Various studies have suggested that combinations of therapies that target different stages of anti-tumor immunity may be synergistic, which can lead to potent and more prolonged responses that can achieve long-lasting tumor destruction. Nurses associated with cancer patients should have a better understanding of the immunotherapies and targeted therapies, such as their efficacy profiles, mechanisms of action, as well as management and prophylaxis of adverse events. Indeed, this knowledge will be important in establishing care for cancer patients receiving immunotherapies and targeted therapies for cancer treatment. Moreover, nurses need a better understanding regarding targeted therapies and immunotherapies to ameliorate outcomes in patients receiving these therapies, as well as management and early detection of possible adverse effects, especially adverse events associated with checkpoint inhibitors and various other therapies that control T-cell activation causing autoimmune toxicity. Nurses practice in numerous settings, such as hospitals, home healthcare agencies, radiation therapy facilities, ambulatory care clinics, and community agencies. Therefore, as compared to other members of the healthcare team, nurses often have better opportunities to develop the essential rapport in providing effective nurse-led patient education, which is important for effective therapeutic outcomes and continuance of therapy. In this article, we have particularly focused on providing a detailed overview on targeted therapies and immunotherapies used in cancer treatment, management of their associated adverse events, and the impact as well as strategies of nurse-led patient education.

[PMID: 37048797 PMCID: PMC10094844 DOI: 10.3390/jcm12072714] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 03/26/2023] [Accepted: 04/01/2023] [Indexed: 04/14/2023] Open
Abstract
The term osteomalacia (OM) refers to a series of processes characterized by altered mineralization of the skeleton, which can be caused by various disorders of mineral metabolism. OM can be genetically determined or occur due to acquired disorders, among which the nutritional origin is particularly relevant, due to its wide epidemiological extension and its nature as a preventable disease. Among the hereditary diseases associated with OM, the most relevant is X-linked hypophosphatemia (XLH), which manifests in childhood, although its consequences persist into adulthood where it can acquire specific clinical characteristics, and, although rare, there are XLH cases that reach the third or fourth decade of life without a diagnosis. Some forms of OM present very subtle initial manifestations which cause both considerable diagnosis and treatment delay. On occasions, the presence of osteopenia and fragility fractures leads to an erroneous diagnosis of osteoporosis, which may imply the prescription of antiresorptive drugs (i.e., bisphosphonates or denosumab) with catastrophic consequences for OM bone. On the other hand, some radiological features of OM can be confused with those of axial spondyloarthritis and lead to erroneous diagnoses. The current prevalence of OM is not known and is very likely that its incidence is much higher than previously thought. Moreover, OM explains part of the therapeutic failures that occur in patients diagnosed with other bone diseases. Therefore, it is essential that clinicians who treat adult skeletal diseases take into account the considerations provided in this practical review when focusing on the diagnosis and treatment of their patients with bone diseases.

Abstract
Lung cancer is the leading cause of cancer-related mortality worldwide. The discovery of tyrosine kinase inhibitors effectively targeting EGFR mutations in lung cancer patients in 2004 represented the beginning of the precision medicine era for this refractory disease. This great progress benefits from the identification of driver gene mutations, and after that, conventional and new technologies such as NGS further illustrated part of the complex molecular pathways of NSCLC. More targetable driver gene mutation identification in NSCLC patients greatly promoted the development of targeted therapy and provided great help for patient outcomes including significantly improved survival time and quality of life. Herein, we review the literature and ongoing clinical trials of NSCLC targeted therapy to address the molecular pathways and targeted intervention progress in NSCLC. In addition, the mutations in EGFR gene, ALK rearrangements, and KRAS mutations in the main sections, and the less common molecular alterations in MET, HER2, BRAF, ROS1, RET, and NTRK are discussed. The main resistance mechanisms of each targeted oncogene are highlighted to demonstrate the current dilemma of targeted therapy in NSCLC. Moreover, we discuss potential therapies to overcome the challenges of drug resistance. In this review, we manage to display the current landscape of targetable therapeutic patterns in NSCLC in this era of precision medicine.

Do Early Phase Oncology Trials Predict Clinical Efficacy in Subsequent Biomarker-Enriched Phase III Randomized Trials? Target Oncol 2022; 17:665-674. [PMID: 36197635 DOI: 10.1007/s11523-022-00920-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/16/2022] [Indexed: 10/10/2022]
Abstract
BACKGROUND Promising early phase trial results of biomarker-targeted therapies have occasionally led to regulatory approval. OBJECTIVE We examined if early phase trials were predictive of efficacy in randomized controlled trials (RCTs) with matching treatment settings. PATIENTS AND METHODS Cancer drug RCTs conducted between January 2006 and March 2021 were identified through Clinicaltrials.gov. Biomarker-enriched RCTs and associated matching early phase trials were included. Trial pairs were compared using objective response rate (ORR) and progression-free survival (PFS). We examined whether early phase trials results were associated with RCT results using logistic regression. RESULTS The search yielded 2157 unique RCTs and 27 RCTs pairing with early phase trials were included. Based on average difference of trial pairs, ORR was similar (1.6%; 95% confidence interval (CI) - 2.5 to 5.6, p = 0.50) and median PFS was higher in early phase trials (2.0 months; 95% CI 0.9-3.0, p < 0.05). On an individual pair basis, there was large variability in difference for ORR (range - 23.9 to 20.2%) and median PFS (range - 0.8 to 7.4 months). The probability of the RCT meeting its primary endpoint is 95% (95% prediction interval (PI) 72.8-99.3%) when the early phase trial ORR is 77.7%. CONCLUSIONS Overall, in early phase trials, ORR has minimal bias and median PFS appears to be slightly overestimated. Substantial variability between trials suggests early phase trial results may be inconsistent with subsequent RCT. Early phase trial results may be associated with RCTs meeting their primary endpoint when ORR is very high; however, caution must be exercised when using early phase trials as representative of RCTs.

Abstract
Background: Aberrant mesenchymal–epithelial transition/hepatocyte growth factor (MET/HGF) regulation presented in a wide variety of human cancers. MET exon 14 skipping, copy number gain (CNG), and kinase domain mutations/arrangements were associated with increased MET activity, and considered to be oncogenic drivers of non-small cell lung cancers (NSCLCs). Methods: We retrospectively analyzed 564 patients with MET alterations. MET alterations were classified into structural mutations or small mutations. MET CNG, exon 14 skipping, gain of function (GOF) mutations, and kinase domain rearrangement were defined as actionable mutations. Results: Six hundred thirty-two MET mutations were identified including 199 CNG, 117 exon 14 skipping, 12 GOF mutations, and 2 actionable fusions. Higher percentage of MET structural alterations (CNG + fusion) were detected in advanced NSCLC patients. Moreover, MET CNG was enriched while exon 14 skipping was rare in epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI)-treated advanced NSCLC patients. Ten of the 12 MET GOF mutations were also in EGFR-TKI-treated patients. Fifteen (68.1%) of the 22 patients treated with crizotinib or savolitinib had a partial response. Interestingly, one patient had a great response to savolitinib with a novel MET exon 14 skipping mutation identified after failure of immune-checkpoint inhibitor. Conclusions: Half of the MET alterations were actionable mutations. MET CNG, exon 14 skipping and GOF mutations had different distribution in different clinical scenario but all defined a molecular subgroup of NSCLCs for which MET inhibition was active.

[PMID: 34589973 PMCID: PMC8474193 DOI: 10.1016/j.jtocrr.2020.100108] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Accepted: 10/12/2020] [Indexed: 11/11/2022] Open
Abstract
Introduction Taletrectinib (AB-106/DS-6051b) is an oral, potent selective ROS1 and pan-NTRK tyrosine kinase inhibitor (TKI). Preclinically, taletrectinib has activity against ROS1 G2032R solvent-front mutation. Methods Patients with ROS1+ NSCLC enrolled into two phase 1 studies conducted in United States (U101, NCT02279433) and Japan (J102, NCT02675491) were analyzed for objective response rate (ORR) by the Response Evaluation Criteria in Solid Tumors version 1.1, progression-free survival, and safety. Results A total of 22 patients with ROS1+ NSCLC out of the total 61 patients enrolled were analyzed. Taletrectinib was given at the oral dose of 400 mg, 600 mg, 800 mg, and 1200 mg once daily and 400 mg twice daily as part of the dose-escalation schema. Data cutoff was August 19, 2020. Median follow-up time for all 22 patients was 14.9 months (95% confidence interval [CI]: 4.1–33.8). A total of 18 patients with ROS1+ were assessable for response. The confirmed ORR for ROS1 TKI-naive patients (N = 9) was 66.7% (95% CI: 35.4–87.9) with a disease control rate of 100% (70.1–100). The confirmed ORR for crizotinib pretreated patients (N = 6) was 33.3% (95% CI: 9.7–70.0) with a disease control rate of 88.3% (95% CI: 443.6–97.0). The median progression-free survival for ROS1 TKI-naive patients (N = 11) was 29.1 months (95% CI: 2.6–not reached) and 14.2 months (95% CI: 1.5–not reached) for crizotinib-refractory only patients (N = 8). The most common treatment-related adverse events were alanine transaminase elevations (72.7%), aspartate transaminase elevations (72.7%), nausea (50.0%), and diarrhea (50.0%). Grade 3 or higher adverse events were alanine transaminase elevations (18.2%), aspartate transaminase (9.1%), and diarrhea (4.5%). Conclusions Taletrectinib (AB106/DS6051b) has a meaningful clinical activity in patients with advanced ROS1+ NSCLC who are ROS1 TKI-naive or crizotinib-refractory and a manageable safety profile.

Abstract
Precision medicine is essential for the modern care of a patient with cancer. Comprehensive molecular profiling of the tumor itself is necessary to determine the presence or absence of certain targetable abnormalities or biomarkers. In particular, lung cancer is a disease for which targetable genomic alterations will soon guide therapy in the majority of cases. In this comprehensive review of solid tumor-based biomarkers, we describe the genomic alterations for which targeted agents have been approved by the United States Food and Drug Administration (FDA). While focusing on alterations leading to approvals in a tumor-agnostic fashion (MSI-h, TMB-h, NTRK) and on those alterations with approvals in multiple malignancies (BRAF, ERBB2, RET, BRCA, PD-L1), we also describe several biomarkers or indications that are likely to lead to an approved drug in the near future (e.g., KRAS G12C, PD-L1 amplification, HER2 overexpression in colon cancer, HER2 mutations in lung cancer). Finally, we detail the current landscape of additional actionable alterations (EGFR, ALK, ROS1, MET) in lung cancer, a biomarker-rich malignancy that has greatly benefitted from the precision oncology revolution.

Abstract
Non-small cell lung cancer (NSCLC) is a lethal non-immunogenic malignancy and proto-oncogene ROS-1 tyrosine kinase is one of its clinically relevant oncogenic markers. The ROS-1 inhibitor, crizotinib, demonstrated resistance due to the Gly2032Arg mutation. To curtail this resistance, researchers developed lorlatinib against the mutated kinase. In the present study, a receptor-ligand pharmacophore model exploiting the key features of lorlatinib binding with ROS-1 was exploited to identify inhibitors against the wild-type (WT) and the mutant (MT) kinase domain. The developed model was utilized to virtually screen the TimTec flavonoids database and the retrieved drug-like hits were subjected for docking with the WT and MT ROS-1 kinase. A total of 10 flavonoids displayed higher docking scores than lorlatinib. Subsequent molecular dynamics simulations of the acquired flavonoids with WT and MT ROS-1 revealed no steric clashes with the Arg2032 (MT ROS-1). The binding free energy calculations computed via molecular mechanics/Poisson-Boltzmann surface area (MM/PBSA) demonstrated one flavonoid (Hit) with better energy than lorlatinib in binding with WT and MT ROS-1. The Hit compound was observed to bind in the ROS-1 selectivity pocket comprised of residues from the β-3 sheet and DFG-motif. The identified Hit from this investigation could act as a potent WT and MT ROS-1 inhibitor.

Abstract
Introduction: Gene fusions are frequent chromosomal aberrations in solid tumors. In Lung cancer (LC) several druggable-fusions involving tyrosine kinase receptor genes have been described, including ALK, ROS1, RET and NTRK. In non-small cell lung cancer, testing for targetable fusions has become a part of routine clinical practice, greatly impacting therapeutic choice for patients with these aberrations. Although substantial technologies for gene fusion detection have been implemented over time including; cytogenetic, Fluorescence in situ hybridization (FISH), Immunohistochemistry (IHC), Retro-transcription Real-Time PCR (RT-qPCR), to Next Generation Sequencing (NGS), nCounter system (Nanostring technology), several critical issues remain. To date, only the companion diagnostic tests FISH and IHC for ALK-rearrangements and NGS for ROS1-rearrangments were approved. Other fusion approved tests are currently unavailable.Areas covered: In this review, we explore current diagnostic problems of gene fusion detection relative to the technologies available, in order to clarify future standardization of analyses which determine therapeutic choices.Expert opinion: The establishment of a gold standard, an effective diagnostic algorithm, and a standardized interpretation for the analysis of each druggable-fusions in lung cancer is essential for adequate therapeutic management.

Hess LM, Han Y, Zhu YE, Bhandari NR, Sireci A. Characteristics and outcomes of patients with RET-fusion positive non-small lung cancer in real-world practice in the United States. BMC Cancer 2021; 21:28. [PMID: 33402119 PMCID: PMC7786962 DOI: 10.1186/s12885-020-07714-3] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 12/07/2020] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Contradictory and limited data are available about the presentation and outcomes of patients with RET-fusion positive metastatic NSCLC as compared to patients without RET fusions. This observational study utilizing a linked electronic health records (EHR) database to genomics testing results was designed to compare characteristics, tumor response, progression-free (PFS) and overall survival (OS) outcomes by RET fusion status among patients with metastatic NSCLC treated with standard therapies. METHODS Adult patients with metastatic NSCLC with linked EHR and genomics data were eligible who received systemic anti-cancer therapy on or after January 1, 2011. Adjusted, using all available baseline covariates, and unadjusted analyses were conducted to compare tumor response, PFS and OS between patients with RET-fusion positive and RET-fusion negative disease as detected by next-generation sequencing. Tumor response outcomes were analysed using Fisher's exact test, and time-to-event analyses were conducted using Cox proportional hazards model. RESULTS There were 5807 eligible patients identified (RET+ cohort, N = 46; RET- cohort, N = 5761). Patients with RET fusions were younger, more likely to have non-squamous disease and be non-smokers and had better performance status (all p < 0.01). In unadjusted analyses, there were no significant differences in tumor response (p = 0.17) or PFS (p = 0.06) but OS was significantly different by RET status (hazard ratio, HR = 1.91, 95% CI:1.22-3.0, p = 0.005). There were no statistically significant differences by RET fusion status in adjusted analyses of either PFS or OS (PFS HR = 1.24, 95% CI:0.86-1.78, p = 0.25; OS HR = 1.52, 95% CI: 0.95-2.43, p = 0.08). CONCLUSIONS Patients with RET fusions have different baseline characteristics that contribute to favorable OS in unadjusted analysis. However, after adjusting for baseline covariates, there were no significant differences in either OS or PFS by RET status among patients treated with standard therapy prior to the availability of selective RET inhibitors.

Abstract
On May 8, 2020, the FDA granted accelerated approval to selpercatinib for (i) adult patients with metastatic RET fusion-positive non-small cell lung cancer (NSCLC), (ii) adult and pediatric patients ≥12 years of age with advanced or metastatic RET-mutant medullary thyroid cancer who require systemic therapy, and (iii) adult and pediatric patients ≥12 years of age with advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine refractory (if radioactive iodine is appropriate). Approval was granted on the basis of the clinically important effects on the overall response rate (ORR) with prolonged duration of responses observed in a multicenter, open-label, multicohort clinical trial (LIBRETTO-001, NCT03157128) in patients whose tumors had RET alterations. ORRs within the approved patient populations ranged from 64% [95% confidence interval (CI), 54-73] in prior platinum-treated RET fusion-positive NSCLC to 100% (95% CI, 63-100) in systemic therapy-naïve RET fusion-positive thyroid cancer, with the majority of responders across indications demonstrating responses of at least 6 months. The product label includes warnings and precautions for hepatotoxicity, hypertension, QT interval prolongation, hemorrhagic events, hypersensitivity, risk of impaired wound healing, and embryo-fetal toxicity. This is the first approval of a drug specifically for patients with RET alterations globally.

Abstract
The FDA-approved entrectinib on August 15, 2019, for the treatment of adult and pediatric patients 12 years of age and older with solid tumors that have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have progressed following treatment or have no satisfactory alternative therapy. Approval was based on demonstration of a durable overall response rate of 57% (95% confidence interval: 43-71), including a complete response rate of 7%, among 54 entrectinib-treated patients with 10 different tumor types harboring an NTRK fusion enrolled in one of three single-arm clinical trials. The durations of response ranged from 2.8 months to 26.0+ months; 68% of responses lasted ≥ 6 months. The most serious toxicities of entrectinib are congestive heart failure, central nervous system effects, skeletal fractures, hepatotoxicity, hyperuricemia, QT prolongation, and vision disorders. Adverse reactions were manageable through dose interruptions (46%), dose reductions (29%), or discontinuation of entrectinib (9%). This is the third approval of a cancer drug for treatment of a tissue agnostic, biomarker-defined cancer.

Abstract
ROS1 fusion-positive (ROS1+) NSCLC was discovered in 2007, the same year as the discovery of ALK-positive (ALK+) NSCLC but has trailed ALK+ NSCLC in terms of development. There seems to be a differential response to ROS1 inhibitors, which depend on fusion partners (CD74, SLC34A2, or SDC4); thus, knowledge of the fusion partners in ROS1+ NSCLC is important. To date (end of February 2020), we have identified 24 unique 5' fusion partners of ROS1 in ROS1+ NSCLC from published literature and congress proceedings. Thus, we published this catalog for easy reference.

Abstract
This work summarizes the benefit and risk of the results of clinical trials submitted to the US Food and Drug Administration of therapies for the treatment of non-small cell lung cancer (NSCLC) using number needed to benefit (NNB) and number needed to harm (NNH) metrics. NNB and NNH metrics have been reported as potentially being more patient centric and more intuitive to medical practitioners than more common metrics, such as the hazard ratio, and valuable to medical practitioners in complementing other metrics, such as the median time to event. This approach involved the characterization of efficacy and safety results in terms of NNB and NNH of 30 clinical trials in advanced NSCLC supporting US Food and Drug Administration approval decisions from 2003 to 2017. We assessed trends of NNB over time of treatment (eg, for programmed death 1 inhibitors) and variation of NNB across subpopulations (eg, characterized by epidermal growth factor receptor mutation, programmed death ligand 1 expression, Eastern Cooperative Oncology Group performance status, age, and extent of disease progression). Furthermore, the evolution of NNB of treatments for advanced NSCLC was charted from 2003 to 2017. Across subpopulations, NNB, on average, was 4 patients for approved targeted therapies in molecularly enriched populations, 11 patients for approved therapies in nonmolecularly enriched populations, and 23 patients for withdrawn or unapproved therapies. Furthermore, the NNB analysis showed variation for attributes of epidermal growth factor receptor mutations, level of programmed death 1 expression, Eastern Cooperative Oncology Group performance status, etc. When considering the best-case subpopulations and available drugs, the NNB frontier reduced from an estimated value of 7.7 in 2003 to an estimated value of 2.5 in 2017 at the estimated median overall survival-equal to 6 months-of an untreated patient.

Abstract
OPINION STATEMENT The MET exon 14 skipping mutation is found in approximately 3% of lung adenocarcinomas and slightly more than 2% of lung squamous cell carcinomas. In recent years, more and more evidence has shown that MET inhibitors have achieved good anti-tumor effect in patients with MET exon 14 skipping mutation, suggesting that MET exon 14 skipping mutation may be a new target for NSCLC patients. Patients with positive MET exon 14 skipping mutation are recommended to be administered MET inhibitors, and crizotinib is recommended by the NCCN guideline. Due to the presence of gene amplification, second site mutation, bypass activation, and pathological type transformation, one of the inevitable problems of targeted therapy is drug resistance. If type I MET inhibitors (crizotinib, capmatinib, tepotinib, savolitinib) drug resistance is developed, type II MET inhibitors (cabozantinib, glesatinib, merestinib) can be considered.

Abstract
Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide and has a poor prognosis. Current treatments for advanced NSCLC included traditional chemotherapy, radiotherapy, targeted therapy, and immunotherapy. The efficacy of targeted therapy relies on oncogene addiction. Mesenchymal-epithelial transition factor (MET) gene can encode unconventional receptor tyrosine kinases with pleiotropic functions, when signals are abnormally activated, it can initiate and maintain tumor transformation, promote cell proliferation, survival, tumor invasion and angiogenesis. Thus, it is a promising therapeutic target. Previous studies have shown that elevated levels of HGF and/or overexpression of c-Met are associated with poor prognosis in lung cancer. In preclinical and clinical trials, c-MET inhibitors have shown some antitumor activity in NSCLC. Although the efficacy results of MET inhibitors in Phase III clinical trials are disappointing, given the molecular heterogeneity of NSCLC, only subgroups of patients with MET gene alterations may benefit from c-MET inhibitors. The challenge for the future is to screen out the potential beneficiaries. To solve this problem, there is need for large data analysis for the detection methods and treatment effects, to establish standards that meet the MET activation status, and determine reliable thresholds to achieve effective patient stratification and clinical decision making. This article summarized the structure of the hepatocyte growth factor (HGF)/c-Met axis, the different mechanisms of MET addiction, as well as MET amplification as acquired resistance mechanism to epidermal growth factor receptor-tyrosine kinase inhibitors, the latest advances of MET inhibitors, and immuotherapy in the treatment of NSCLC with MET alterations.

Abstract
BACKGROUND ROS1 gene fusion represents a specific subtype of non-small cell lung cancer (NSCLC). Crizotinib is recommended for ROS1-positive NSCLC due to its favorable outcome in published clinical trials. However, due to the low incidence of ROS1-positive NSCLC, there is limited information on real-world clinical outcomes in patients treated with either crizotinib or platinum-based doublet chemotherapy. METHODS Outcomes were recorded in 102 patients with stage Ⅲb or Ⅳ NSCLC who were treated at four Chinese hospitals between April, 2010 and June, 2019. RESULTS Of the 102 patients followed, 71.6% were females, 81.4% were non-smokers, and 98.0% had adenocarcinoma. First-line treatment with crizotinib achieved a significantly longer median progression-free survival (PFS) compared with platinum-based chemotherapy (14.9 months vs 8.5 months, respectively; P < .001). Next-generation sequencing (NGS) identified 61 patients who had ROS1 fusion variants, including CD74 (n = 33) and non-CD74 (n = 28) variants. In patients harboring CD74 fusion variants, the median PFS with first-line crizotinib treatment was significantly longer than in those harboring non-CD74 fusion variants (20.1 months vs 12.0 months, respectively; P = .046). However, in patients treated with platinum-based chemotherapy, there was no significant difference in PFS between the CD74 and non-CD74 variant groups (8.6 months vs 4.3 months, respectively; P = .115). Overall survival (OS) was not reached. CONCLUSIONS First-line therapy with crizotinib is more beneficial than platinum-based chemotherapy in patients with advanced NSCLC with different ROS1 fusion variants. Patients harboring CD74 fusion variants appear to respond better to crizotinib.

Abstract
OBJECTIVES Food and Drug Administration (FDA) approved crizotinib for advanced ROS1-rearranged (ROS1+) non-small-cell lung cancer (NSCLC) patients due to a single-arm study PROFILE 1001. However, there is no direct comparison between crizotinib and platinum-pemetrexed chemotherapy. MATERIALS AND METHODS Clinical data of advanced ROS1+NSCLC patients treated with first-line crizotinib or platinum-pemetrexed chemotherapy between August 2010 and December 2017 were analyzed. RESULTS Seventy-seven patients were eligible, including 30 (39.0%) in the crizotinib group and 47 (61.0%) in the platinum-pemetrexed chemotherapy group. The median follow-up was 28.1 months (95% confidence interval [CI]: 19.2-39.0). The objective response rate (ORR) of crizotinib (86.7%, 95% CI: 73.3-96.7) was higher than that of platinum-pemetrexed chemotherapy (44.7%, 95% CI: 29.8-57.4, P < .001). The disease control rate (DCR) was 96.7% (95% CI: 90.0-100) in the crizotinib group and 85.1% (95% CI: 74.5-95.7) in the chemotherapy group (P = .140). Significantly longer progression-free survival (PFS) was observed in the patients treated with crizotinib (18.4 months, 95% CI: 6.4-30.3) versus platinum-pemetrexed chemotherapy (8.6 months, 95% CI: 6.9-10.3, P < .001). Overall survival (OS) was also compared between the two groups and no significant difference was seen (Not reach vs 28.4 months [95% CI: 20.7-36.0], P = .176). Notably, a total of 37 patients have treatment crossover after the failure of first-line treatment. Among those patients, difference in OS was not statistically significant between seven patients who have given first-line crizotinib (38.6 months, 95% CI: 0-81.0) and 30 patients who have given platinum-pemetrexed chemotherapy initially (32.8 months, 95% CI: 11.9-53.8, P = .805). CONCLUSIONS Our results suggested that first-line crizotinib had higher ORR and longer PFS than platinum-pemetrexed chemotherapy in patients with advanced ROS1+NSCLC, but the differences were not observed for OS.

Abstract
ALK and ROS1 kinases have become promising therapeutic targets since Crizotinib was used to treat non-small-cell lung cancer clinically. Aiming to explore new potent inhibitors, a series of 2-amino-4-(1-piperidine) pyridine derivatives that stabilized a novel DFG-shifted conformation in the kinase domain of ALK were designed and synthesized on the base of lead compound A. Biological evaluation highlighted that most of these new compounds could also potently inhibit ROS1 kinase, leading to the promising inhibitors against both ROS1 and ALK. Among them, the representative compound 2e stood out potent anti-proliferative activity against ALK-addicted H3122 and ROS1-addicted HCC78 cell lines (IC50 = 6.27 μM and 10.71 μM, respectively), which were comparable to that of Crizotinib. Moreover, 2e showed impressive enzyme activity against clinically Crizotinib-resistant ALKL1196M with an IC50 value of 41.3 nM, which was about 2-fold more potent than that of Crizotinib. 2e also showed potent inhibitory activity in about 6-fold superior to Crizotinib (IC50: 104.7 nM vs. 643.5 nM) in Ba/F3 cell line harboring ROS1G2032R. Furthermore, molecular modeling disclosed that all the representative inhibitors could dock into the active site of ALK and ROS1, which gave a probable explanation of anti Crizotinib-resistant mutants. These results indicated that our work has established a path forward for the generation of anti Crizotinib-resistant ALK/ROS1 dual inhibitors.

Abstract
AIM To determine factors associated with survival in de novo stage IV, non-small cell lung cancer (NSCLC) patients possessing epidermal growth factor receptor mutations (EGFRmut+ ) receiving tyrosine kinase inhibitors (TKI) in the first-line setting. METHODS The Glans-Look Lung Cancer Database was used to retrospectively review stage IV EGFRmut+ NSCLC patients diagnosed 2010-2016 receiving first-line TKI. Patients with overall survival times in the upper quartile (≥34 months) were designated "long-term survivors" (LTS), the remaining deemed "average-term survivors" and characteristics between these groups were compared in univariate analysis, and multivariable models constructed to determine predictors of outcome. RESULTS Of 170 eligible patients, median overall survival was 21 months. LTS were significantly more likely to be of Asian ethnicity, be never-smokers and not possess brain or bone metastases at diagnosis. Asian and non-Asian patients were comparable, save for an increased propensity of Asian patients to be never smokers and have normal-range BMI. Multivariable analysis revealed Asian ethnicity [hazard ratio (HR) = 0.65; P = 0.016] and never-smoking history (HR = 0.65; P = 0.034) as indicators of improved outcome, and presence of brain metastasis at diagnosis an indicator of poor outcome (HR = 2.21; P < 0.001). CONCLUSIONS Analysis of this population-based cohort identifies never-smoking history and absence of brain metastasis along with Asian ethnicity as an independent prognosticators of favorable outcome, and reveals Asian patients to be clinicopathologically similar to non-Asian patients. These findings suggest Asian patients represent a unique subpopulation within EGFRmut+ NSCLC who may possess different biological underpinnings of NSCLC.

Abstract
The ros1 kinase is an oncogenic driver in non-small-cell lung cancer (nsclc). Fusion events involving the ROS1 gene are found in 1%-2% of nsclc patients and lead to deregulation of a tyrosine kinase-mediated multi-use intracellular signalling pathway, which then promotes the growth, proliferation, and progression of tumour cells. ROS1 fusion is a distinct molecular subtype of nsclc, found independently of other recognized driver mutations, and it is predominantly identified in younger patients (<50 years of age), women, never-smokers, and patients with adenocarcinoma histology. Targeted inhibition of the aberrant ros1 kinase with crizotinib is associated with increased progression-free survival (pfs) and improved quality-of-life measures. As the sole approved treatment for ROS1-rearranged nsclc, crizotinib has been demonstrated, through a variety of clinical trials and retrospective analyses, to be a safe, effective, well-tolerated, and appropriate treatment for patients having the ROS1 rearrangement. Canadian physicians endorse current guidelines which recommend that all patients with nonsquamous advanced nsclc, regardless of clinical characteristics, be tested for ROS1 rearrangement. Future integration of multigene testing panels into the standard of care could allow for efficient and cost-effective comprehensive testing of all patients with advanced nsclc. If a ROS1 rearrangement is found, treatment with crizotinib, preferably in the first-line setting, constitutes the standard of care, with other treatment options being investigated, as appropriate, should resistance to crizotinib develop.

Abstract
NTRK gene fusions involving either NTRK1, NTRK2 or NTRK3 (encoding the neurotrophin receptors TRKA, TRKB and TRKC, respectively) are oncogenic drivers of various adult and paediatric tumour types. These fusions can be detected in the clinic using a variety of methods, including tumour DNA and RNA sequencing and plasma cell-free DNA profiling. The treatment of patients with NTRK fusion-positive cancers with a first-generation TRK inhibitor, such as larotrectinib or entrectinib, is associated with high response rates (>75%), regardless of tumour histology. First-generation TRK inhibitors are well tolerated by most patients, with toxicity profiles characterized by occasional off-tumour, on-target adverse events (attributable to TRK inhibition in non-malignant tissues). Despite durable disease control in many patients, advanced-stage NTRK fusion-positive cancers eventually become refractory to TRK inhibition; resistance can be mediated by the acquisition of NTRK kinase domain mutations. Fortunately, certain resistance mutations can be overcome by second-generation TRK inhibitors, including LOXO-195 and TPX-0005 that are being explored in clinical trials. In this Review, we discuss the biology of NTRK fusions, strategies to target these drivers in the treatment-naive and acquired-resistance disease settings, and the unique safety profile of TRK inhibitors.

Abstract
The FDA approved pembrolizumab on May 23, 2017, for the treatment of adult and pediatric patients with unresectable or metastatic, microsatellite instability-high (MSI-H), or mismatch repair deficient (dMMR) solid tumors that have progressed following prior treatment and who have no satisfactory alternative treatment options and for the treatment of unresectable or metastatic MSI-H or dMMR colorectal cancer that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. The FDA granted the approval based on an understanding of the biology of MSI-H/dMMR across different tumors along with the clinically important effects on overall response rate (ORR) observed in patients who were enrolled in 1 of 5 single-arm clinical trials. The ORR was 39.6% among 149 patients with 15 different tumor types (95% confidence interval, 31.7-47.9), with a 7% complete response rate. The duration of response ranged from 1.6+ months to 22.7+ months, with 78% of responses lasting ≥6 months. Overall, the adverse event profile of pembrolizumab was similar to the adverse event profile observed across prior trials that supported the approval of pembrolizumab in other indications. This approval of pembrolizumab is the first time that the FDA has approved a cancer treatment for an indication based on a common biomarker rather than the primary site of origin.

Abstract
AIMS The growing number of genomically targeted therapies has made genomic testing an important part of the care for patients with non-small cell lung cancer. However, limited tissue availability, cost and long turnaround times can create barriers to efficient genomic testing and subsequent treatment. Effective approaches to reduce these barriers are needed. METHODS 302 advanced lung adenocarcinomas from consecutive patients seen at University Hospitals Cleveland Medical Center (UHCMC) were tested inhouse using a hybrid DNA/RNA next-generation sequencing (NGS) panel. Sample testing was reflexed from pathology for all stage III or IV tumours. Genomic alterations were tiered according to their clinical relevance and reported with guideline-recommended therapies. Clinical implications of genomic testing results were assessed by manual chart review. RESULTS With a sample cohort consisting of 64% biopsies, 16% excisions/resections and 20% fine needle aspirations, the assay was reliable with a 95% success rate. The average turnaround time from receipt of unstained formalin-fixed paraffin embedded slides to reporting was 4.8±2.1 days, half of the recommended 10 days and similar to single-gene testing. Alterations with Food and Drug Administration-approved or the National Cancer Center Network guideline-recommended targeted therapies were found in 18% of cases. Within this group, 60% of patients went on genomically driven therapies. CONCLUSIONS We found our reflexed inhouse NGS assay to be reliable, cost-effective and efficient. Incorporation of reflex testing with our NGS assay led to an expansion of successful genomic profiling for all guideline-recommended alterations, and by including an expanded number of alterations within our panel we obtained clinically useful information outside the guidelines without changing cost or efficiency. This approach has enabled UHCMC clinicians to efficiently initiate genomically driven therapies for patients with lung adenocarcinoma.

Abstract
Introduction Lung cancer is the leading cause of cancer mortality worldwide, despite advances in management, especially with targeted agents and immunotherapy. Numerous oncogenes have been identified that control the growth of these malignancies. Anaplastic lymphoma kinase (ALK) is a tyrosine kinase that develops distorted functioning as a result of chromosomal rearrangement. Crizotinib, a tyrosine kinase inhibitor (TKI), was approved by the Food and Drug Administration (FDA) in 2011 for the treatment of advanced ALK-positive non-small-cell lung cancer (NSCLC). Patients and methods In this chart review, we compiled data from two cancer hospitals in Kuwait and Saudi Arabia which were collected from patients with advanced NSCLC treated between January 2013 and September 2017 with crizotinib after diagnosed with ALK-positive disease. Crizotinib 250 mg BID was given orally with/without food intake. We assessed overall survival (OS), objective response rate (ORR), progression-free survival (PFS), duration of the response, and dose reduction/cessation. Results De-identified data from 38 subjects were compiled. Their median age was 53 years, 65.8% were male, the 1-year OS was 88%, and the PFS was 16.5 months. Two cases (5.3%) had a complete response (CR), while 17 (44.7%) had a partial response (PR). Side effects of grade III/IV occurred, including elevated transaminase levels, diarrhea, and prolonged QT intervals, in 8% patients, with dose reduction in six patients (15.8%). Conclusion In NSCLC, crizotinib is a viable treatment option with good response and tolerable toxicity for patients with ALK-positive advanced disease.

Abstract
The abnormal expression of c-ros oncogene1 receptor tyrosine kinase (ROS1) has been identified as clinically actionable oncogenic driver in non-small-cell lung cancer. Since crizotinib was approved by the US FDA for the treatment of advanced ROS1-positive non-small-cell lung cancer, ROS1 kinase has become a promising therapeutic target. Under the guidance of some advanced computer-assisted technologies, such as structure-based drug design, homology modeling and lipophilic efficiency parameters, several potent and selective inhibitors against wild-type and mutant ROS1 were designed and synthesized. In this article, we will review a series of scaffolds targeting ROS1 kinase from the hit-to-drug evolution strategies of their representative compounds and it is hoped that these design strategies would facilitate medicinal chemists to optimize the process of drug design.

Abstract
Lung cancer, the leading cause of cancer deaths worldwide, is characterized with malignant cell growth. Advances in next-generation sequencing has helped us further understand RNA and identify novel circular RNAs (circRNAs) that may be useful in the early diagnosis and treatment of lung cancer. Similar to other noncoding RNAs, circRNAs present diverse biological functions in normal and disease states, including various types of cancers. This review focuses mainly on the poorly understood functions of circRNA in lung cancer. This paper also summarizes the recent advances in circRNA biogenesis, analyzes the role of circRNAs in cancers, and discusses the potential mechanisms of circRNAs in lung cancer.

Abstract
This article summarizes the FDA review of the efficacy supplement supporting approval of dabrafenib and trametinib administered concurrently for BRAF V600E‐mutant non‐small cell lung cancer. On June 22, 2017, the Food and Drug Administration expanded indications for dabrafenib and trametinib to include treatment of patients with metastatic non‐small cell lung cancer (NSCLC) harboring BRAF V600E mutations. Approval was based on results from an international, multicenter, multicohort, noncomparative, open‐label trial, study BRF113928, which sequentially enrolled 93 patients who had received previous systemic treatment for advanced NSCLC (Cohort B, n = 57) or were treatment‐naïve (Cohort C, n = 36). All patients received dabrafenib 150 mg orally twice daily and trametinib 2 mg orally once daily. In Cohort B, overall response rate (ORR) was 63% (95% confidence interval [CI] 49%–76%) with response durations ≥6 months in 64% of responders. In Cohort C, ORR was 61% (95% CI 44%–77%) with response durations ≥6 months in 59% of responders. Results were evaluated in the context of the Intergroupe Francophone de Cancérologie Thoracique registry and a chart review of U.S. electronic health records at two academic sites, characterizing treatment outcomes data for patients with metastatic NSCLC with or without BRAF V600E mutations. The treatment effect of dabrafenib 150 mg twice daily was evaluated in 78 patients with previously treated BRAF mutant NSCLC, yielding an ORR of 27% (95% CI 18%–38%), establishing that dabrafenib alone is active, but that the addition of trametinib is necessary to achieve an ORR of >40%. The most common adverse reactions (≥20%) were pyrexia, fatigue, nausea, vomiting, diarrhea, dry skin, decreased appetite, edema, rash, chills, hemorrhage, cough, and dyspnea. Implications for Practice. The approvals of dabrafenib and trametinib, administered concurrently, provide a new regimen for the treatment of a rare subset of non‐small cell lung cancer (NSCLC) and demonstrate how drugs active for treatment of BRAF‐mutant tumors in one setting predict efficacy and can provide supportive evidence for approval in another setting. The FDA also approved the first next‐generation sequencing oncology panel test for simultaneous assessment of multiple actionable mutations, which will facilitate selection of optimal, personalized therapy. The test was shown to accurately and reliably select patients with NSCLC with the BRAF V600E mutation for whom treatment with dabrafenib and trametinib is the optimal treatment.

Abstract
BACKGROUND advanced-stage non-small cell lung cancer (NSCLC) is characterized by having limited treatment options and thus a poor prognosis. However, new treatment options, in the form of targeted agents (TA), have emerged during recent years. This systematic review aims to provide an overview of the accessible literature in PubMed evaluating TA used on NSCLC patients, and the resulting survival outcomes. METHOD this systematic literature review was conducted by reviewing all relevant literature in PubMed. Six separate searches were performed: Three searches where controlled entry terms were used and three free text searches. Furthermore, other relevant publications were included manually. A total of seventy-two studies met the search criteria and were thus further analyzed and evaluated. RESULTS In the included studies, various TAs and their effect on different molecular targets have been evaluated. Clinical responses vary considerably among the different genetic aberrations. The majority of studies evaluated TA for epidermal growth factor receptor (EGFR) mutations and TA for echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) rearrangements. Studies regarding the use of TA for Rat sarcoma (RAS), rapidly accelerated fibrosarcoma (RAF), ROS proto-oncogene 1 (ROS1) rearrangement, Receptor tyrosine-protein kinase erbB-2 (ERBB2), Phosphatidylinositol 3-kinase (PIK3CA)/v-akt murine thymoma viral oncogene homolog; protein kinase B(AKT)/Phosphatase and tensin homolog deleted on chromosome 10(PTEN), The mammalian target of rapamycin (mTOR), and Mesenchymal-epithelial transition factor (MET) were included as well. In general, studies comparing treatment outcomes in EGFR-mutated patients and EML4-ALK (ALK) rearranged patients after use of either TA or standard chemotherapy, present significant better results after TA. CONCLUSIONS This systematic review provides an overview of available literature in PubMed regarding NSCLC and TA. Included studies point toward that TA appears to be a promising therapeutic tool in treating NSCLC patients and use of TA is expected to result in improved treatment outcomes.

Abstract
CONTEXT - Patients with non-small cell lung cancer harboring ALK receptor tyrosine kinase ( ALK), ROS proto-oncogene 1 ( ROS1), and ret proto-oncogene ( RET) gene rearrangements can benefit from specific kinase inhibitors. Detection of fusion genes is critical for determining the best treatment. Assessing rearrangements in non-small cell lung cancer remains challenging, particularly for lung cytology. OBJECTIVE - To examine the possible application of the multiplex, transcript-based NanoString system (NanoString Technologies, Seattle, Washington) in the evaluation of fusion genes in lung adenocarcinoma samples. DATA SOURCES - This study is a narrative literature review. Studies about NanoString, gene fusions, and lung adenocarcinoma were collected from PubMed (National Center for Biotechnology Information, Bethesda, Maryland). We found 7 articles about the application of the NanoString system to detect fusion genes on formalin-fixed, paraffin-embedded tumor tissues and one article evaluating the adequacy of lung cytologic specimens for NanoString gene expression analysis. CONCLUSIONS - To maximize the yield of molecular tests on small lung biopsies, the NanoString nCounter system has been suggested to detect fusion genes. NanoString fusion gene assays have been successfully applied on formalin-fixed, paraffin-embedded tissues. Although there are only a few studies available, the application of NanoString assays may also be feasible in lung cytology. According to available data, the NanoString system could strengthen the routine molecular characterization of lung adenocarcinoma.

Abstract
Background Crizotinib is recommended as first-line therapy in ROS1-driven lung adenocarcinoma. However, the optimal first-line therapy for this subgroup of lung cancer is controversial according to the available clinical data. Case presentation Here, we describe a 57-year-old man who was diagnosed with stage IIIB lung adenocarcinoma and EGFR/KRAS/ALK-negative tumors. The patient received six cycles of pemetrexed plus cisplatin as first-line therapy and then pemetrexed as maintenance treatment, with a progression-free survival (PFS) of 42 months. The patient relapsed and underwent re-biopsy. EZR-ROS1 fusion mutation was detected by next-generation sequencing (NGS). The patient was prescribed crizotinib as second-line therapy and achieved a PFS of 6 months. After disease progression, lorlatinib was administered as third-line therapy, with a favorable response. Conclusions Prolonged PFS in patients receiving pemetrexed chemotherapy might be related to the EZR-ROS1 fusion mutation. Lorlatinib is an optimal choice in patients showing crizotinib resistance.

Abstract
With the aim of discovering potential and selective inhibitors targeting ROS1 kinase, we rationally designed, synthesized and evaluated two series of novel 2-amino-pyridine derivatives with 1-phenylethoxy at C-3 and C-4 position. The enzymic assays results indicated that six of the new compounds 13b-13d and 14a-14c showed remarkably higher inhibitory activities against ROS1 kinase. The most promising compounds, 13d and 14c displayed the most desired ROS1 inhibitory activity with IC50 values of 440 nM and 370 nM respectively. Furthermore, 13d and 14c displayed ROS1 inhibitory selectivity of about 7-fold and 12-fold, relative to that of ALK sharing about 49% amino acid sequence homology in the kinase domains. They also showed good anti-proliferative effects against ROS1-addicted HCC78 cell lines with the IC50 values of 8.1 μM and 65.3 μM, respectively. Moreover, molecular docking and molecular dynamics simulation studies disclosed that compound 14c and 13d shared similar binding poses with Crizotinib except the selective binding site of ROS1. It also gave a probable molecular explanation for their activity and selectivity, which the methoxyl group in benzene ring was the crucial to the selectivity to ROS1 versus ALK.

Abstract
The c-ros oncogene 1 (ROS1) has proven to be an important cancer target for the treatment of various human cancers. The anaplastic lymphoma kinase inhibitor crizotinib has been granted approval for the treatment of patients with ROS1 positive metastatic non-small-cell lung cancer by the Food and Drug Administration on 2016. However, serious resistance due to the secondary mutation of glycine 2032 to arginine (G2032R) was developed in clinical studies. Loratinib (PF-06463922), a macrocyclic analog of crizotinib, showed significantly improved inhibitory activity against wild-type (WT) ROS1 and ROS1G2032R mutant. To provide insights into the inhibition mechanism, molecular dynamics simulations and free energy calculations were carried out for the complexes of loratinib with WT and G2032R mutated ROS1. The apo-ROS1WT and apo-ROS1G2032R systems showed similar RMSF distributions, while ROS1G2032R-loratinib showed significantly higher than that of WT ROS1-loratinib, which revealed that the binding of loratinib to ROS1G2032R significantly interfered the fluctuation of protein. Calculations of binding free energies indicate that G2032R mutation significantly reduces the binding affinity of loratinib for ROS1, which arose mostly from the increase of conformation entropy and the decrease of solvation energy. Furthermore, detailed per-residue binding free energies highlighted the increased and decreased contributions of some residues in the G2032R mutated systems. The present study revealed the detailed inhibitory mechanism of loratinib as potent WT and G2032R mutated ROS1 inhibitor, which was expected to provide a basis for rational drug design.

Abstract
INTRODUCTION Mitosis is necessary to sustain life and is followed immediately by cell division into two daughter cells. Microtubules play a key role in the formation of the mitotic spindle apparatus and cytokinesis at the end of mitosis. Various anti-microtubule agents such as taxanes and vinca alkaloids are widely used in the treatment of advanced non-small cell lung cancer (NSCLC) but their use is associated with hematologic toxicity profile, acquired resistance and hypersensitivity reactions. Areas covered: The Nab-paclitaxels are the more recent antimitotic agents approved in NSCLC showing a better tolerability and activity when compared to previous ones. Despite this, the outcome of patients with advanced non-small cell lung cancer is poor. Due to the key role of mitosis, research is focused on the identification of new mitotic drug targets other than microtubule inhibitors, such as cell cycle targets, aurora kinases and Polo-like kinases. Expert opinion: Despite improvements in chemotherapeutic choices and supportive care, the majority of patients experience a deteriorating quality of life and significant toxicities associated to a poor outcome. Thus, the therapeutic management of patients with advanced NSCLC represents an ongoing challenge and novel agents targeting mitosis are under investigation.

Abstract
INTRODUCTION The discovery of activating genetic and their use as predictive biomarkers for targeted therapy, such as tyrosine kinase inhibitors (TKIs), has changed the treatment paradigm of non-small cell lung cancer (NSCLC). As a result, epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) TKIs have become the standard first-line treatment. Since then, other kinds of targetable oncogenic alterations have been identified in NSCLC. Several novel, molecularly-targeted TKIs have now achieved regulatory approval, while many others are currently in early- or late-phase clinical trial testing. These TKIs have significantly impacted and changed clinical outcomes for advanced NSCLC. Areas covered: In this review, the authors discuss recent evidence and progress in targeted therapies, especially small molecular tyrosine kinase inhibitors, matched with their biomarkers for the treatment of advanced NSCLC. Expert commentary: Although targeted therapies dramatically improve the outcome of patients with NSCLC harboring specific oncogenic alterations, molecular and clinical resistance almost invariably develops. New TKIs specifically active in molecular subgroups of NSCLC or the resistance setting have now been developed. The development of additional TKIs and rational combinations may further improve outcomes of NSCLC.

Abstract
Importance Novel intermediate end points may be useful to detect signals of early activity and prioritize new therapies to treat patients with advanced malignant neoplasms, including metastatic non-small cell lung cancer (mNSCLC). Objective To explore milestone rate, a proposed intermediate end point for immunotherapy trials. Data Sources Trials submitted to the US Food and Drug Administration with more than 150 patients and in which the intention-to-treat population was assessed were identified. Study Selection An initial meta-analysis identified 14 randomized clinical trials for treatment of mNSCLC with active controls submitted to the US Food and Drug Administration from January 1, 2003, through December 31, 2013. An additional 11 randomized clinical trials submitted from January 1, 2014, through December 31, 2016 were included. Data Extraction and Synthesis Two investigators abstracted data and pooled data to compare trial-level milestone ratios with conventional end points. Main Outcomes and Measures Trial-level milestone ratios for milestone rates were calculated for overall response rate (ORR) within 6 months, 9-month progression-free survival (PFS), 9-month overall survival (OS), and 12-month OS. A weighted linear regression model evaluated associations between milestone ratios and hazard ratios (HRs). Experimental and control arms of trials testing immunotherapy, targeted therapy, and other trials were pooled to compare Kaplan-Meier survival estimates in the 3 therapeutic classes. Results A total of 20 013 unique patients (65.4% male and 34.6% female; mean age, 60 [range, 18-92] years) with advanced lung cancer were identified in 25 unique trials. A moderate association was observed between 12-month OS milestone ratio and OS HR (R2 = 0.80; 95% CI, 0.63-0.91) and 9-month OS milestone ratio and OS HR (R2 = 0.67; 95% CI, 0.49-0.82). No associations were observed between 9-month PFS milestone ratio and OS HR (R2 = 0.19; 95% CI, 0.03-0.49) or 6-month ORR and OS HR (R2 = 0.05; 95% CI, 0.0001-0.31). The aggregated Kaplan-Meier analysis of immunotherapy trials vs chemotherapy revealed an OS HR of 0.69 (95% CI, 0.63-0.75) and PFS HR of 0.82 (95% CI, 0.76-0.89). Targeted therapy trials vs chemotherapy had an OS HR of 0.98 (95% CI, 0.80-1.19) and PFS HR of 0.48 (95% CI, 0.42-0.56). Conclusions and Relevance This analysis of milestone rates suggests a moderate association between OS milestones at 12 or 9 months and OS HR but not 9-month PFS or 6-month ORR milestones and OS HR. Although OS at 12 months had the strongest association with OS HR, it may not be the optimal time for future trials, which will increasingly have immunotherapy as the control, deploy new biomarker-enrichment strategies, and likely enroll patients with longer survival. Milestone rates may be useful as a complementary tool to summarize or interpret trial results or as a secondary end point in exploratory studies.
