e21209 Background: Immune checkpoint inhibitors (ICI) are now the standard of care in the treatment of non-small cell lung cancer (NSCLC). ICIs may be used as monotherapy or in combination with chemotherapy. Increased recruitment of inflammatory cells in the tumor micro-environment is associated with a poor response to ICIs. Although obesity is a risk factor for many types of cancers, including lung cancer, it is associated with a low systemic inflammation state. This creates an effect known as the “obesity paradox,” resulting in better treatment-related outcomes in overweight and obese patients receiving ICIs. However, in obese patients, the neutralizing interleukin (IL) - 1β level is high, which can decrease the responsiveness to ICI. We aim to study the effect of increased weight on treatment-related outcomes in NSCLC patients receiving ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs, such as pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab, alone or in combination with chemotherapy. Overweight was defined as having a BMI of 25 – 29.9 while obesity was defined as having a BMI of ≥ 30. Overall survival (OS), progression free survival (PFS), best radiographic response, and the time to achieve radiographic response were evaluated. Cox regression univariate and multivariate analyses were performed. Logistic regression and Chi-square tests were applied. Results: Of the 178 patients with NSCLC, 81% had adenocarcinoma, and 19% had squamous, adenosquamous, or large cell carcinoma. The majority of patients were female (56.2% vs. 43.8%). Overall, 48.6% patients were overweight or obese. The objective response rate (ORR) was 45.1% and the disease control rate (DCR) was 75.8%. The ORR was 37% in overweight/obese patients compared to 52% in patients with a normal weight (p = 0.06). The DCR was 76% vs. 73.9%, (p = 0.7). The median time to achieve the best radiographic response was 3.7 months in overweight/obese patients compared to 2.5 months in those of normal weight (p = 0.2). A considerably higher proportion of the patients progressed in overweight/obese category (80.7% vs. 69.3%, P = 0.08). However, there was no significant difference in median PFS between the two categories (7.4 vs. 8.1 months, P = 0.2). The overall survival was not significant different between both categories (15.9 vs. 16.8 months, P = 0.5). Conclusions: Our study suggests that obesity and overweight status can result in a low response rate to ICIs in NSCLC patients and can delay the time to achieve the best radiographic response per RECIST criteria. However, we did not observe any significant impact on the overall or progression-free survival. A large, population-based study will help to elucidate the impact of weight on the responsiveness to ICI.

e21202 Background: Increased systemic inflammatory state and increased inflammation within tumor micro-environment (TME) have been associated with a worse prognosis and lower responsiveness to immune checkpoint inhibitors (ICI). Systemic inflammatory immune index (SII) reflects the changes in the systemic inflammatory matrix. Studies have shown the association of SII with cancer survival and treatment outcomes. We aim to study the effect of SII on treatment outcomes in non-small cell lung cancer (NSCLC) patients being treated with ICI. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs (pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab) alone or in combination with chemotherapy. SII is the product of platelets multiplied by neutrophils divided by lymphocytes. Baseline and 8-week SIIs were obtained. Radiographic response, duration of radiographic response (date of best response to radiographic progression), overall survival (OS), and progression-free survival (PFS) were evaluated. A high SII was defined as a value greater than the median SII. Cox regression univariate and multivariate analyses were performed. Logistic regression, t-test, and Chi-square tests were applied. Results: Overall, 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. The majority of the patients were female (56.2% vs. 43.8%). Median SII at baseline was 1335. The objective response rate (ORR) was 45.1%. The disease control rate was 75.8%. The ORR was 51% in patients receiving ICI first-line compared to 35% in those who received ICI as a second-line therapy. At baseline, there was no difference in the mean SII between responders and non-responders (2146.2 vs. 1917.5, P = 0.5); however at 8 weeks, the mean SII was significantly lower in responders compared to non-responders (1198.8 vs. 2880.2, P = 0.02). A total of 15 (10.9%) patients were found to have pseudoprogression or mixed response on follow-up imaging. Among these, 11(73.3%) patients had low SII at 8 weeks (P = 0.04). The median OS was significantly higher in patients with low SII at baseline (29.6 months vs. 10.1 months, P = 0.001 95% CI 10.6 – 22.1). Similarly, there was a significant difference in median PFS in patients with low SII (14.6 months vs. 6.7 months, P = 0.002, 95% CI 5.6 – 11.6). There was no correlation between high or low SII on the incidence of immune-related adverse events. Conclusions: SII may have significant impact on OS and PFS and could be serially monitored to assess the response to ICI. A low SII may help to differentiate pseudoprogression vs. true progression. Prospective studies are needed to validate these findings. Further, it will be interesting to see if SII could be incorporated into predictive models to determine the duration of cytotoxic therapy in selected patients.

PURPOSE We conducted a randomized trial to investigate the value of the addition of cisplatin to teniposide (VM26) and to investigate the schedule dependence of the topoisomerase II inhibitor VM26, in advanced non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS Two hundred twenty-five NSCLC patients were randomized to receive VM26 120 mg/m2 on days 1, 3, and 5 or 360 mg/m2 on day 1 only, either as a single drug or in combination with cisplatin 80 mg/m2 on day 1. Cycles were repeated every 3 weeks. Response rates, side effects, and survival were compared according to the 2 x 2 factorial design of this study. RESULTS The response rate of the two cisplatin-containing arms was superior to that of the two arms that contained VM26 only (22% v 6%, P < .001); progression-free survival and survival times were also longer in the cisplatin-containing arms (median, 4.3 v 2.2 months, P = .003; median 7.2 v 5.9 months, P = .008, respectively). Toxicity was significantly higher in the cisplatin-containing arms; the most frequent side effects were leukopenia, nausea and vomiting, and alopecia. The schedule of VM26 did not significantly influence the response rate, progression-free survival interval, or survival duration. However, the response rate of the 1-day administration was significantly lower than that of the 3-day administration when given as single drugs. CONCLUSION The addition of cisplatin to VM26 improves the response rate, progression-free survival interval, and survival duration over VM26 alone, although at the cost of a significant increase in toxicity. Cisplatin should be considered as the basis for combination chemotherapies in advanced NSCLC.

e21137 Background: Immune checkpoint inhibitors (ICI) are the standard of care in the treatment of non-small cell lung cancer (NSCLC). ICIs are commonly used in combination with chemotherapy but may be used as monotherapy in selected cases. Registration trials have shown a response rate of 40–50% in such patients and a durable response in some patients. However, there are no reliable predictive markers that determines the response and its durability. Recruitment of the inflammatory cells in the tumor microenvironment (TME) can determine the response to ICIs and an increased inflammatory state can be a poor prognostic factor. Peripheral inflammatory markers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) can reflect the inflammatory changes within the TME. We aim to study the effect of high NLR and PLR on the radiographic response and its durability in NSCLC patients treated with ICIs. Methods: We conducted a retrospective analysis on 178 NSCLC patients treated with ICIs such as pembrolizumab, nivolumab, ipilimumab/nivolumab or atezolizumab either alone or in combination with chemotherapy. Radiographic response, and the duration of radiographic response (date of best response to radiographic progression), NLR, and PLR were calculated at baseline and 8 weeks since the start of ICI. High NLR and PLR was defined as greater than the median NLR and PLR values. Cox regression univariate and multivariate analyses were performed. Logistic regression and Chi-square tests were applied. Results: Overall 81% patients had adenocarcinoma and 19% patients had squamous, adenosquamous or large cell carcinoma. Majority of the patients were female (56.2% vs. 43.8%). The objective response rate (ORR) was 45.1% and the disease control rate (DCR) was 75.8%. The ORR was 51% in patients receiving ICI as first line therapy compared to 35% in patients who received ICI as a second line therapy. There was statistically significant difference in median duration of response in patients with high vs. low NLR (9.8 months vs. 18 months, P = 0.01, 95% CI 10.9– 26.2) and high vs. low PLR (9.0 months vs. 17 months, P = 0.03 95% CI 10.9–24.33) at baseline. The baseline odds ratio (OR) of response in the high NLR and high PLR group was 0.73 (P = 0.5, 95% CI 0.36–1.64) and 0.63 (P = 0.2, 95% CI 0.32–1.23), respectively. However, the odds to respond to ICI decreased significantly in patients with high NLR and PLR at 8 weeks [NLR (OR = 0.16, P = 0.0001, 95% CI 0.06–0.43)] and [PLR (OR = 0.27, P = 0.005, 95% CI 0.1–0.6). Conclusions: NLR and PLR may be reliable surrogate markers determining the durability of response to ICI in NSCLC patients. Standard imaging studies and serial monitoring may be beneficial to monitor the response to ICIs. However, prospective studies are needed to develop predictive and prognostic models utilizing these indices.

Background: Immune checkpoint inhibitors (ICI) plus radiotherapy (RT) have been suggested as an emerging combination in non-small cell lung cancer (NSCLC) patients. However, little is known about the magnitude of its benefits and potential clinical predictors. Objective: To assess the effects of this combination on the increase in overall and progression-free survival. Data sources: The MEDLINE and CANCERLIT (1970–2020) electronic databases were searched, and the reference lists of included studies were manually searched. Study selection: Studies were included if they were comparative studies between combination ICI-RT and ICI or RT alone in advanced or metastatic NSCLC patients. Overall survival (OS) was analyzed according to the treatment strategy. Data extraction: Data on population, intervention, and outcomes were extracted from each study, in accordance with the intention-to-treat method, by two independent observers and combined using the DerSimonian method and Laird method. Results: Compared to ICI or RT alone, ICI-RT significantly increased the 1-year and 3-year OS RR by 0.75 (95% CI 0.64–0.88; p = 0.0003) and 0.85 (95% CI 0.78–0.93; p = 0.0006), respectively. Furthermore, there was a statistically significant benefit on 1- and 3-year progression-free survival (RR 0.73 (95% CI, 0.61–0.87; p = 0.0005) and RR 0.82 (95% CI 0.67–0.99; p = 0.04), respectively). Conclusions: In patients with advanced or metastatic NSCLC, combination ICI-RT increases 1- and 3-year OS and progression-free survival compared to ICI or RT alone.

Abstract Background: This study was designed to evaluate the treatment effect of S-1 following PEM-containing treatment. Methods: This retrospective study included patients with advanced (c-stage III or IV, UICC 7th) or recurrent NSCLC who received S-1 monotherapy following the failure of previous PEM-containing chemotherapy at 6 hospitals in Japan. Primary endpoint: Overall response rate (ORR). Secondary endpoint: Disease control rate (DCR), time to treatment failure (TTF), progression-free survival (PFS), and overall survival (OS). Results: A total of 53 NSCLC patients met the criteria. Forty-six patients had adenocarcinoma (88.7%) and no patients had squamous cell carcinoma. Thirty-one patients (58.5%) received the standard S-1 regimen and 18 patients (34.0%) received the modified S-1 regimen. ORR was 1.9% (95% confidential interval (CI): 0.00-10.1%). Median TTF, PFS, and OS were 65 days, 84 days, and 385 days, respectively. Conclusion: Although there were several limitations in this study, the ORR of S-1 after PEM in patients with non-SQ NSCLC was low compared to the historical control. It might be one of the choices to avoid S-1 treatment in PEM-treated patients who need tumor shrinkage.

Immunotherapy with immune checkpoint inhibitors (ICIs) has changed the therapeutic management of advanced non-small cell lung cancer (aNSCLC) over the last decade. However, there is an unmet need for clinically useful biomarkers in this patient subgroup. The aim of this study was to combine baseline clinical characteristics of aNSCLC patients, in the form of a scoring system, and to investigate its predictive and prognostic value in NSCLC patients treated with ICIs. A total of 112 patients with advanced (stages IIIA to IV) NSCLC, treated with nivolumab or pembrolizumab, were enrolled in this study. Patras Immunotherapy Score (PIOS) was developed based on four of the studied parameters (performance status (PS), body mass index (BMI), age, and lines of treatment (LOT), which were incorporated into our formula (PS × BMI/ LOT × age). PIOS score was strongly associated with best overall responses (BOR), with those patients having benefit/good response (stable disease (SD) or partial (PR) or complete response (CR), achieving a higher score compared to patients who developed progressive disease (PD) (p < 0.001). Furthermore, PIOS score was associated with progression-free survival (PFS), since high-score patients had longer PFS (p < 0.001, hazard ratio (HR) = 0.469). Moreover, PIOS was associated with post-immunotherapy overall survival (OS), with high-score patients having improved OS (log-rank p = 0.019). This study suggests that a combination of baseline parameters, which give rise to PIOS score, may predict the best response of NSCLC patients treated with anti-program cell death -1 (PD-1) monotherapy as well as it may have a potent prognostic value for PFS and post immunotherapy OS.

9530 Background: The SWI/SNF chromatin remodeling complex is reported to be involved in sensitivity and resistance to immune checkpoint inhibitor (ICI). However, their role in non-small cell lung cancer (NSCLC) remains unclear. We examined the relationship between SWI/SNF complex mutations and clinical outcomes of ICI in patients with NSCLC. Methods: Of 1017 lung cancer patients enrolled in LC-SCRUM-IBIS, 350 patients were analyzable for whole-exome sequencing (WES). WES data were used to analyze the presence of mutations in 29 major subunits of the SWI/SNF complexes. ARID1A and SMARCA4 mutations were also evaluated in a targeted NGS panel (Oncomine comprehensive assay, OCA). PD-L1 expression by 22C3, tissue tumor mutational burden (tTMB) by WES, STK11 and KEAP1 mutations by WES or OCA were also assessed. Durable clinical benefit (DCB) including CR, PR and SD > 6 mos to ICI, progression-free survival (PFS) and overall survival (OS) were compared in status of each of SWI/SNF complex mutations and other factors. Results: At least one mutation in any subunits of the SWI/SNF complex was present in 28% of NSCLC patients. The most common mutated subcomplexes were SMARCA4 (12%), BAF (7%: ARID1A, 4%), non-canonical BAF (3%), PBAF (3%), and SMARCA2 (2%). Of 101 NSCLC patients treated with PD-1/PD-L1 inhibitors, SMARCA4 mutations tended to be associated with lower DCB (16 vs 31%) and shorter median PFS (1.9 vs 3.6 m) and OS (7.4 vs 18.1m). Patients with ARID1A mutations tended to have better clinical outcomes (DCB, 40 vs 28%) compared to those without mutations. No significant associations were found between PD-L1 expression and SMARCA4 or ARID1A mutations. Patients with STK11/KEAP1 mutations had lower rate of PD-L1 expression (TPS > 50%) (18% vs 48%, P = 0.03) and worse clinical outcomes (DCB, 6 vs 33%) compared to those without mutations. There was no significant association between a tTMB status and clinical outcome. Conclusions: SMARCA4 and ARID1A mutations appear to affect clinical outcomes of ICI in NSCLC patients. These findings indicate that SWI/SNF complex mutations may serve as a predictive biomarker for ICI in NSCLC patients.

e21636 Background: Afatinib is an irreversible ErbB family blocker, which is approved for the treatment of advanced non-small cell lung cancer (NSCLC) patients with activating EGFR mutations. Here we report the final results of the prospective non-interventional study (NIS) GIDEON, which was initiated to investigate the efficacy and tolerability of afatinib in the daily clinical routine in Germany. Methods: EGFR-mutated NSCLC patients were treated with afatinib according to label until progression, death or discontinuation. Efficacy (progression-free survival (PFS) rate at 12 months, objective response rate, ORR; disease control rate, DCR; progression-free survival, PFS and overall survival, OS) was prospectively assessed by investigators. Data about tolerability were collected during routine treatment. Results: In total, 161 patients were enrolled at 41 sites in Germany, 152 patients received at least one dose of afatinib (treated set; TS) and 146 patients were treated according to the protocol (PPS). The majority of patients for the entire TS had exon 19 deletions (64.5%), followed by L858R point mut. (22.4%) and uncommon mut. (exon 18-21 point mut.; 13.1%). The primary objective was PFS-rate at 12 months, which was 50.2% in the PPS. Median PFS amounted to 12.2 months. ORR and DCR were 74.6% and 91.5% in the PPS, respectively. Median OS was 30.4 months with 1- and 2-year survival rates of 79.1% and 57.7%, respectively. Among pat. with uncommon EGFR-mut., the 12-months PFS rate was 40.2% with a mPFS of 10.7 months. ORR and DCR were 83.3% and 91.7%, respectively. The most frequent documented adverse drug reactions (ADRs) were diarrhea and rash/acne with 13.8% and 7.2% of grade 3 but no grade 4 or higher. Conclusions: Afatinib is a standard therapy for patients with activating EGFR mut. in Germany. The final results of this prospective NIS confirm the robust clinical data for afatinib in the clinical routine setting, including patients with uncommon exon 18-21 point mutations. Clinical trial information: NCT02047903.
