7531 Background: Mutations in KRAS are present in ~25% of patients with advanced NSCLC. Preclinical data support the role of mammalian target of rapamycin (mTOR) in KRAS mediated oncogenesis. Ridaforolimus is an inhibitor of mTOR which has been shown to have efficacy in advanced endometrial cancer and soft tissue sarcoma. Everolimus, another mTOR inhibitor was previously evaluated in unselected patients with advanced NSCLC and found to have a response rate <5%. We hypothesized that by enrichment for patients with NSCLC and KRAS mutations, treatment with ridaforolimus would be associated with prolonged stable disease relative to available standard treatments for NSCLC. Methods: Patients with stage IIIB/IV non-small cell lung cancer with KRAS mutation who had received prior chemotherapy for NSCLC began treatment with oral ridaforolimus 40 mg once daily on a 5 day/week schedule. After 8 weeks, patients with >30% tumor shrinkage remained on ridaforolimus and patients with >20% tumor growth discontinued treatment. Patients with stable disease were randomized 1:1 to placebo or ridaforolimus. The primary endpoint of the study was progression-free survival (PFS) after randomization. Results: 79 patients were enrolled (40 women, median age 58 [range 28-85]). The overall response rate (CR+PR) at 8 weeks was 1/79 (1%, 95% CI 0-7%).  28 patients with stable disease at 8 weeks were randomized to ridaforolimus or placebo.  Median PFS based on investigator assessment from randomization was significantly longer with ridaforolimus (4 months) than placebo (2 months, p=0.013, HR 0.36).  Median OS from randomization was 18 months in the ridaforolimus treated arm and 5 months in the placebo treated group, (HR 0.46, p=0.09).  The most common grade ≥3 adverse events were fatigue (10%), mucositis/stomatitis (10%), pneumonia (10%), dyspnea (9%), diarrhea (6%), and hyperglycemia (6%). Conclusions: In patients with KRAS mutant NSCLC who had stable disease after 8 weeks of ridaforolimus, ridaforolimus was associated with prolonged progression-free survival.  Further evaluation of ridaforolimus in this patient population is warranted.

PurposeTo evaluate the efficacy of cetuximab added to first-line gemcitabine/platinum in chemotherapy-naïve patients with advanced non–small-cell lung cancer (NSCLC).Patients and MethodsIn this noncomparative, randomized trial, chemotherapy-naïve patients with recurrent/metastatic NSCLC (stage IV or stage IIIB with malignant pleural effusion) were eligible. Patients received cisplatin (75 mg/m2IV, every 3 weeks) or carboplatin (area under the concentration-versus-time curve of 5 intravenously [IV], every 3 weeks), and gemcitabine (1,250 or 1,000 mg/m2IV, days 1 and 8) plus cetuximab (400 mg/m2IV day 1, followed by 250 mg/m2weekly), in arm A, or chemotherapy alone, in arm B. Response rate was the primary end point; safety, progression-free survival, and overall survival were secondary end points.ResultsSixty-five patients were randomly assigned to arm A and 66 to arm B. Partial responses were observed in 18 patients (27.7%; 95% CI, 17.3 to 40.2) in arm A and 12 (18.2%; 95% CI, 9.8 to 29.6) in arm B. Median progression-free survival was 5.09 months for arm A (95% CI, 4.17 to 5.98) and 4.21 months (95% CI, 3.81 to 5.49) in arm B. Median overall survival was 11.99 months (95% CI, 8.80 to 15.18) and 9.26 months (95% CI, 7.43 to 11.79) in arms A and B, respectively. Overall toxicity was acceptable and consistent with the profiles of the individual agents.ConclusionFirst-line treatment with cetuximab plus gemcitabine/platinum is well tolerated and can be administered safely in patients with advanced NSCLC. Differences in response rate, progression-free survival, and overall survival suggest that the addition of cetuximab to platinum/gemcitabine may improve clinical outcomes. Larger studies are in progress to address this hypothesis.

Metabolomic Profiling

Background: Despite remarkable success of immunotherapies with checkpoint blockade antibodies targeting programmed cell death protein 1 (PD-1), the majority of patients with non-small-cell lung cancer (NSCLC) have yet to receive durable benefits. We used the metabolomic profiling of early on-treatment serum to explore predictors of clinical outcomes of anti-PD-1 treatment in patients with advanced NSCLC.Methods: We recruited 74 Chinese patients who had stage IIIB/IV NSCLC-proven tumor progression and were treated with PD-1 inhibitor. The study was comprised of a discovery cohort of patients treated with nivolumab and two validation cohorts of patients receiving tislelizumab or nivolumab. Serum samples were collected 2–3 weeks after the first infusion of PD-1 inhibitor. Metabolomic profiling of serum was performed using ultrahigh performance lipid chromatograph-mass spectrometry. The serum metabolite biomarkers were identified using an integral workflow of nontargeted metabolomic data analysis.Results: A serum metabolite panel consisting of hypoxanthine and histidine was identified and validated as a predictor of response to PD-1 blockade treatment in patients with advanced NSCLC. High levels of both hypoxanthine and histidine in early on-treatment serum were associated with improved progression-free survival [hazard ratio (HR) = 0.078, 95% confidence interval (CI), 0.027–0.221, p &lt; 0.001] and overall survival (HR = 0.124, 95% CI, 0.039–0.397, p &lt; 0.001) in the discovery cohort. The serum metabolite panel showed a high sensitivity and specificity in distinguishing responders and non-responders in the validation cohorts 1 and 2, with an area under the receiver-operating characteristic curve of 0.933 and 1.000, respectively. High levels of serum hypoxanthine and histidine were correlated with improved progression-free survival in the validation cohort 1 (HR = 0.137, 95% CI, 0.040–0.467, p = 0.001) and in the validation cohort 2 (HR = 0.084, 95% CI, 0.009–0.762, p = 0.028).Conclusion: Our results revealed that hypoxanthine and histidine in early on-treatment serum are predictive biomarkers of response to PD-1 blockade therapy in patients with advanced NSCLC. The serum biomarker panel would enable early identification of NSCLC patients who may benefit from PD-1 blockade therapy.

18177 Background: The efficacy and safety of a combined regimen of topotecan and etoposide was tested in patients with relapsed or refractory small-cell lung cancer. Methods: From October 2003 to May 2005, 23 patients who have failed to the previous irinotecan and platinum chemotherapy received intravenous topotecan 1mg/m2 (day 1–5) followed by intravenous etoposide 80mg/m2 (day 1–3). Treatment was repeated every 21 days for a maximum of 6 cycles. Results: Twelve patients were refractory to first-line chemotherapy. Seventeen patients (73.9%) were male and the median age was 63 years. ECOG performance status was 0–1 in 13 (56.5%) patients. The median cycles of chemotherapy was 3. Twenty one patients were assessable for response evaluation. The overall response rate was 17.4% (0 CR, 4 PR, 7 SD, 10 PD) under the intent-to-treat analysis. After a median follow- up of 20.8 months, median progression free survival was 4.7 months and median overall survival was 9.5 months. The estimated 1-year survival rate was 38.7%. In sensitive relapsed patients, 2 achieved tumor response and median progression free survival and overall survival were 5.5 months and 14.5 months. All patients were assessable for toxicity and major toxicities were myelosuppression. Grade 3/4 neutropenia and thrombocytopenia occurred in 18 (78.3%) and 12 (52.2%) patients, respectively. Grade 3/4 febrile neutropenia occurred in 2 patients (8.7 %) and infection in 3 patients (13.0%). There was one treatment-related death due to pneumonia. Conclusions: This salvage regimen failed to demonstrate a considerable response rate compared with monotherapy for relapsed or refractory SCLC. However, the combination of topotecan and etoposide could be further studied for sensitive relapsed patients pretreated with irinotecan and platinum No significant financial relationships to disclose.

e14530 Background: Baselinehigh neutrophil to lymphocyte ratio (NLR) has been associated with inferior overall survival in patients with stage III/IV NSCLC. Inflammation and neutrophilic infiltrates in the tumor microenvironment appear to inhibit anti-tumor immune response. We suspect that NLR might reflect the level of inflammation in tumor microenvironment. The objectives of this study were to evaluate potential relationships between pretreatment NLR and and PFS and OS in advanced NSCLC patients treated with second-line nivolumab or pembrolizumab. Methods: Patients with stage IV NSCLC who received at least one cycle of nivolumab or pembrolizumab after first-line treatment with a platinum doublet between January 2015 and December 2016 were included. Patient demographics including NLR at baseline, date of starting immunotherapy, and date of progression were recorded. The association between NLR and duration of response was assessed using a Mann-Whitney-Wilcoxon test. A cutoff of NLR of 3.5 and 5.0 based on published data (ref) were analyzed for differences in median overall survival and progression free survival. Results: 113 patients were analyzed: median age 68, male/female 38.9%/61.1%, 15% never smoked. The median PFS for patients with NLR < 5 was 4.14 months vs. 2.27 months in those with NLR > 5 (p = 0.031). Overall survival was also impacted by NLR. There were a total of 29 deaths in the cohort, 24 of these occurred in patients with NLR > 3.5 and 5 were in patients with NLR < 3.5. A lower NLR at baseline was significantly associated with improved overall survival (p = 0.036). Conclusions: A low baseline NLR is associated with superior progression free survival and overall survival in metastatic non-small cell lung cancer patients treated with nivolumab or pembrolizumab. These findings suggest that evaluating mediators of inflammation might help to identify potential therapeutic targets which could enhance effectiveness of PD-1 immune check point inhibitors in advanced NSCLC.

e20509 Background: Response Evaluation Criteria in Solid Tumors (RECIST) has been widely utilized to evaluate the new therapeutic strategies in cancer, however, RECIST fails to differentiate the heterogeneity of response in highly active therapies. Depth of response (DepOR), defined as maximum percent change in tumor size compared with baseline, may provide a new strategy to evaluate disease response. In the present study, we studied the association between DepOR and progression-free survival (PFS) in patients with advanced non-small cell lung cancer (NSCLC) treated with epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI). Methods: Advanced NSCLC patients harboring EGFR driver mutation (L858R or 19del) treated with EGFR-TKI from August 2014 to July 2017 in two sites were retrospetively collected for analysis. Patients were divided into four groups by maximal tumor shrinkage (Q1 = 1-25%, Q2 = 26-50%, Q3 = 51-75%, Q4 = 76-100%). Kaplan-Meier curves were plotted for PFS by DepOR and the hazard ratio (HR) was determined through univariable and multivariable Cox regression models. Results: In total, 265 patients were included for analysis. The number for Group Q1-Q4 was 91, 73, 65 and 36, respectively. The greater DepOR was significantly associated with a longer PFS (Log-rank P for trend < 0.0001). The DepOR vs PFS analyses HR were 0.58 (0.42-0.80) for Q2, 0.49 (0.35-0.69) for Q3 and 0.33 (0.22-0.50) for Q4 compared with Q1. In the multivariable cox regression model, abnormal LDH, brain metastasis and male were also found to be associated with poorer PFS (P < 0.05). Conclusions: Greater DepOR was significantly associated with a longer PFS in advanced NSCLC treated with EGFR-TKI, suggesting that it may be a useful clinical outcome to more efficiently evaluate the response of targeted therapy.

Purpose To conduct analyses exploring trial-level and patient-level associations between overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) in advanced non–small-cell lung cancer (NSCLC) trials. Methods We identified 14 trials (N = 12,567) submitted to US Food and Drug Administration since 2003 of treatments for advanced NSCLC. Only randomized, active-controlled trials with more than 150 patients were included. Associations between trial-level PFS hazard ratio (HR), OS HR, and ORR odds ratio were analyzed using a weighted linear regression model. Patient-level responder analyses comparing PFS and OS between patients with and without an objective response were performed using pooled data from all studies. Results In the trial-level analysis, the association between PFS and ORR was strong (R2 = 0.89; 95% CI, 0.80 to 0.98). There was no association between OS and ORR (R2 = 0.09; 95% CI, 0 to 0.33) and OS and PFS (R2 = 0.08; 95% CI, 0 to 0.31). In the patient-level responder analyses, patients who achieved a response had better PFS and OS compared with nonresponders (PFS: HR, 0.40; 95% CI, 0.38 to 0.42; OS: HR, 0.40; 95% CI, 0.38 to 0.43). Conclusion On a trial level, there is a strong association between ORR and PFS. An association between ORR and OS and between PFS and OS was not established, possibly because of cross-over and longer survival after progression in the targeted therapy and first-line trials. The patient-level analysis showed that responders have a better PFS and OS compared with nonresponders. A therapy in advanced NSCLC with a large magnitude of effect on ORR may have a large PFS effect.

Abstract Purpose: Growing numbers of clinical trials test the efficacy of radiotherapy (RT) plus immune checkpoint inhibitors (ICIs), but the number of irradiated sites is not uniform. We aim to evaluate the efficacy of single-site RT plus immunotherapy in oligometastatic non-small cell lung cancer (NSCLC) with smaller disease burdens and low tumor heterogeneity. Methods: We retrospectively identified oligometastatic NSCLC (≤4 metastatic sites) patients treated with PD-1 pathway inhibitors with or without RT to a single lesion in our institution between 2018 and 2020. The primary endpoints were the best objective response rate (ORR) and progression-free survival (PFS) . Results: Of the 152 patients enrolled, 93 and 59 were identified as the ICI alone group and the ICI plus RT group, respectively. The addition of radiotherapy to ICI therapy significant increased the best ORR from 31.2% to 50.8%, p=0.015). The out-of-field (abscopal`) response rate could reach 41.3% (95% CI, 26.5%-56.1%) in the ICI plus RT group. Median progression-free survival was 8.9 months (95%CI, 4.7-13.1 months) with ICI alone versus 13.8 months (95% CI, 9.5-18.1 months) with ICI plus radiotherapy (hazard ratio [HR] 0.568; p=0.035). In an exploratory subgroup analysis of PFS, the addition of RT brought greater benefits in patients with aged <65 years (p=0.016), patients with ECOG PS=0 (p=0.048), patients with 1-2 metastatic sites (p=0.024). No unexpected adverse events or significantly increased toxicities were observed in the experimental arm.Conclusion: Single-site RT plus anti-PD-1 inhibitors significantly increased systemic responses and improved survival outcomes in oligometastatic NSCLC patients.

Abstract Background: AURA study reported 61% objective response rate and progression-free survival of 9.6 months with osimertinib in patients with EGFR/T790M+ non-small cell lung cancer. Due to lack of real-world data, we proposed this study to describe the experience with osimertinib in Spain.Methods: Post-authorization, non-interventional Special Use Medication Program, multicenter, retrospective study in advanced EGFR/T790M+ non-small cell lung cancer. 155 patients were enrolled (August 2016-December 2018) from 30 sites. Primary objective: progression-free survival. Secondary objectives: toxicity profile, objective response rate, and use of health service resources.Results: 70% women, median age 66. 63.9% were non-smokers and 99% had adenocarcinoma. Most had received at least one prior treatment (97%), 91.7% had received previous EGFR-tyrosine kinase inhibitors and 2.8% osimertinib as first-line treatment. At data cutoff, median follow-up was 11.8 months. 155 patients were evaluable for response, 1.3% complete response, 40.7% partial response, 31% stable disease and 11.6% progressive disease. Objective response rate was 42%. Median progression-free survival was 9.4 months. 49% reported an adverse event, the majority of which (78%) were grade 1 or 2. The resource cost study indicates early use is warranted. Conclusion: This study to assess the real-world clinical impact of osimertinib showed high drug activity in pretreated advanced EGFR/T790M+ non-small cell lung cancer, with manageable adverse events.Clinical trial registration number: NCT03790397

PURPOSE Here we report the results of a phase III study, to evaluate whether the addition of cisplatin to radiation therapy (XRT) would improve progression-free survival or overall survival for patients with locally advanced unresectable non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Two hundred forty patients with biopsy-proven unresectable NSCLC without distant metastases or lower-stage medically inoperable patients were randomized to one of two treatment arms. Arm A consisted of thoracic XRT alone, 60 to 65 Gy total tumor dose in daily fractions of 1.80 to 2.00 Gy; and arm B consisted of identical XRT with the addition of cisplatin 70 mg/m2 every 3 weeks for three cycles beginning on the first day of irradiation. RESULTS Two hundred fifteen patients were eligible and assessable. The overall response rate was 50% on the combination arm versus 38% on the XRT-alone arm (P = .076). The median progression-free survival time was 23 versus 22 weeks, respectively (P = .0537). The median survival time was 43 weeks on the combination arm versus 46 weeks on the XRT arm (Poverall = .3469). The 1-, 2-, and 5-year survival rates were 43%, 18%, and 5% on the combination arm versus 45% 13%, and 2% on the XRT arm, respectively. CONCLUSION Cisplatin, administered every 3 weeks, does not significantly improve response rate, progression-free survival, or overall survival when added to thoracic XRT for locally advanced unresectable NSCLC.
