RESUMO
Immune checkpoint inhibitors (ICIs) plus chemotherapy has demonstrated efficacy in resectable non-small-cell lung cancer (NSCLC), yet the optimal period of neoadjuvant immunochemotherapy is undetermined. In a phase II study (neoSCORE, NCT04459611), more neoadjuvant therapy cycles appeared to provide greater pathological remission, and patients with squamous NSCLC had a better major pathological response rate than those with nonsquamous NSCLC. Sintilimab, a monoclonal anti-PD-1 antibody, has shown encouraging antitumor activity and safety in multiple cancers, including NSCLC. Here, we describe the study design of neoSCORE II (NCT05429463), a randomized, open-label, multicenter phase III trial comparing the efficacy and safety of three cycles with four cycles of neoadjuvant sintilimab plus platinum-based chemotherapy in resectable stage IIA-IIIB squamous NSCLC. Trial registration number: NCT05429463 (ClinicalTrials.gov).

Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

The mutation status of tumor tissue DNA (n = 389) of resected stage II-III non-squamous non-small-cell lung cancer (Ns-NSCLC) was analyzed using targeted deep sequencing as an exploratory biomarker study (JIPANG-TR) for the JIPANG study, a randomized phase III study of pemetrexed/cisplatin (Pem/Cis) vs vinorelbine/cisplatin (Vnr/Cis). The TP53 mutation, common EGFR mutations (exon 19 deletion and L858R), and KRAS mutations were frequently detected. The frequency of the EGFR mutation was significant among female patients. Patients with an EGFR mutation-positive status had a significantly shorter recurrence-free survival (RFS) time (24 mo vs not reached) (HR, 1.64; 95% CI, 1.22-2.21; P = .0011 for EGFR mutation status). Multivariable analysis identified both the pathological stage and EGFR mutation status as independent prognostic factors for RFS (HR, 1.78; 95% CI, 1.30-2.44; P = .0003 for disease stage; and HR, 1.57; 95% CI, 1.15-2.16; P = .0050 for EGFR mutation status). This study demonstrated that the EGFR mutation has either a poor prognostic or predictive impact on a poor response to postoperative chemotherapy with platinum doublet chemotherapy for stage II-III Ns-NSCLC patients. This result supports a role for mandatory molecular diagnosis of early-stage Ns-NSCLC for precision oncology and signifies the importance of adjuvant for the 3rd generation tyrosine kinase inhibitor rather than platinum-based chemotherapy. This study is registered with the UMIN Clinical Trial Registry (UMIN 000012237).

BACKGROUND: Rash eruptions are a common side-effect of pemetrexed, for which the administration of 8 mg/day of dexamethasone for 3 days from the day preceding pemetrexed administration is recommended. This study aimed to prospectively assess the effectiveness of prophylactic administration of low-dose dexamethasone for pemetrexed-induced rashes. METHODS: This single-arm, phase II study recruited patients with non-squamous non-small cell lung cancer and malignant pleural mesothelioma scheduled to receive chemotherapy including pemetrexed. Patients received 2 mg of dexamethasone daily from days 2 to 6 after chemotherapy with pemetrexed. The primary endpoint was the 3-week incidence of rash eruptions. RESULTS: Twenty-five patients were enrolled between September 2017 and May 2019. The incidence of rash after 3 weeks was 16.7%. Rashes erupted mainly on the upper half of the body, such as the chest and neck, and were of grades 1 and 2 in 2 patients each. No rashes of grade 3 or higher were observed, and there were no adverse events associated with additional corticosteroids. CONCLUSION: Prophylactic administration of low-dose dexamethasone for 5 days from the day after pemetrexed administration resulted in a milder incidence and severity of rash. These findings may provide a standard preventative strategy for pemetrexed-induced rashes. (Trial identifier: UMIN000025666).

BACKGROUND: Anti-programmed cell death protein (death-ligand) 1 [PD-(L)1] therapy alone [cancer immunotherapy (CIT)-mono] or combined with platinum-based chemotherapy (CIT-chemo) is used as the first-line treatment for patients with metastatic non-small-cell lung cancer (NSCLC). Our study compared clinical outcomes with CIT-mono versus CIT-chemo in the specific clinical scenario of non-squamous (Nsq)-NSCLC with a high PD-L1 expression of ≥50% [tumor proportion score (TPS) or tumor cells (TC)]. METHODS: This was a retrospective cohort study using a real-world de-identified database. Patients with metastatic Nsq-NSCLC with high PD-L1 expression initiating first-line CIT-mono or CIT-chemo between 24 October 2016 and 28 February 2019 were followed up until 28 February 2020. We compared overall survival (OS) and real-world progression-free survival (rwPFS) using the Kaplan-Meier methodology. Hazard ratios (HRs) were adjusted (aHR) for differences in baseline key prognostic characteristics using the inverse probability of treatment weighting methodology. RESULTS: Patients with PD-L1-high Nsq-NSCLC treated with CIT-mono (n = 351) were older and less often presented with de novo stage IV disease than patients treated with CIT-chemo (n = 169). With a median follow-up of 19.9 months for CIT-chemo versus 23.5 months for CIT-mono, median OS and rwPFS did not differ between the two groups [median OS: CIT-chemo, 21.0 months versus CIT-mono, 22.1 months, aHR = 1.03, 95% confidence interval (CI) 0.77-1.39, P = 0.83; median rwPFS: CIT-chemo, 10.8 months versus CIT-mono, 11.5 months, aHR = 1.04, 95% CI 0.78-1.37, P = 0.81]. CIT-chemo showed significant and meaningful improvement in OS and rwPFS versus CIT-mono only in the never-smoker subgroup, albeit among a small sample of patients (n = 50; OS HR = 0.25, 95% CI 0.07-0.83, interaction P = 0.02; rwPFS HR = 0.40, 95% CI 0.17-0.95, interaction P = 0.04). CONCLUSION: Except in the subgroup of never-smoker patients, sparing the chemotherapy in first-line CIT treatment does not appear to impact survival outcomes in Nsq-NSCLC patients with high PD-L1 expression.

BACKGROUND: Advanced non-squamous non-small cell lung cancer (NS-NSCLC) patients without driver gene mutations are usually treated with immune checkpoint inhibitors (ICIs) plus pemetrexed as maintenance therapy after first-line ICIs plus 4-6 cycles of pemetrexed/platinum. Some patients in the real world receive ICIs monotherapy as maintenance therapy. No clinical study has compared the efficacy and safety of ICIs with or without pemetrexed as maintenance therapy. METHODS: We performed a retrospective study analyzing clinical data of patients with NS-NSCLC who were diagnosed in Zhejiang Cancer Hospital from September 2018 to May 2021 and received maintenance therapy after 4-6 cycles of ICIs plus pemetrexed/platinum. Patients were divided into ICIs plus pemetrexed group and ICIs monotherapy group. Progression Free Survival 1 (PFS1) and PFS2, defined as the interval from the date of initial treatment and maintenance therapy to the date of systemic progression/death or the last follow-up, respectively. RESULTS: A total of 120 patients received ICIs with or without pemetrexed as maintenance therapy. Eighty-two patients received ICIs plus pemetrexed as maintenance therapy, and 38 patients received ICIs monotherapy. There were no statistically significant difference in median PFS1 between the ICIs monotherapy group and ICIs plus pemetrexed group (12.00 months vs. 12.07 months, P = 0.979). Among patients with PD-L1 TPS < 1%, the median PFS1 was worse with ICIs monotherapy (9.50 months vs. 14.20 months, P = 0.039). Among patients with PD-L1 TPS ≥50% or 1-49%, the median PFS1 in both groups was not statistically significant (P = 0.866, P = 0.589, respectively). Results for median PFS2 were similar to median PFS1, with statistically significantly different only in patients with PD-L1 TPS < 1% (P = 0.008). The 2-year survival rates of the two groups were similar (66.7% vs. 69.5%, P = 0.812). The incidence of fatigue was significantly higher in the ICIs plus pemetrexed group (P = 0.023). CONCLUSIONS: ICIs with or without pemetrexed can be used as maintenance therapy after first-line ICIs plus 4-6 cycles of pemetrexed/platinum in patients with advanced NS-NSCLC based on PD-L1 expression.

Objective: To evaluate sintilimab compared with other PD-L1 inhibitors in combination with platinum-based doublet chemotherapy as the first-line treatment of non-squamous non-small-cell lung cancer. Methods: A frequentist meta-analysis was used to compare outcomes, including progression-free survival, overall survival, objective response rate, time to response and safety profile. Results: The sintilimab combination arm had progression-free survival comparable to that of the pembrolizumab combination arm (hazard ratio [HR] = 1.00; 95% CI: 0.71, 1.41), the atezolizumab combination arm (HR: 0.81; 95% CI: 0.59, 1.10), the tislelizumab combination arm (HR: 0.75; 95% CI: 0.48, 1.16), the camrelizumab combination arm (HR: 0.80; 95% CI: 0.54, 1.20) and the nivolumab combination arm (HR: 0.72; 95% CI: 0.51, 1.02). Any grade or grade ≥3 adverse event was comparable between PD-L1 inhibitors. Conclusion: Sintilimab showed a comparable efficacy and safety profile when compared with other PD-L1 inhibitors combined with platinum-based doublet chemotherapy as the first-line treatment of locally advanced or metastatic non-squamous non-small-cell lung cancer.
Lung cancer is the most diagnosed cancer and the leading cause of cancer-related mortality in China. Non-small-cell lung cancer (NSCLC) accounts for 85% of all lung cancers, of which non-squamous NSCLC (nsqNSCLC) is the most frequent histologically, comprising 70% of NSCLC. Six different PD-L1 inhibitors (sintilimab, pembrolizumab, camrelizumab, atezolizumab, tislelizumab and nivolumab) in combination with chemotherapy have been approved as the first-line treatment of advanced/metastatic nsqNSCLC patients in China. Since there is no direct evidence of comparable efficacy and safety due to a lack of head-to-head trials among the PD-L1 inhibitors, an indirect comparison was conducted to evaluate sintilimab compared with other PD-L1 inhibitors in combination with platinum-based doublet chemotherapy. The results showed that sintilimab combined with platinum-based doublet chemotherapy showed progression-free survival, overall survival, objective response rate, time to response and safety profile comparable to other PD-L1 inhibitors in combination with platinum-based doublet chemotherapy as the first-line treatment of locally advanced or metastatic nsqNSCLC patients.

While fibroblast growth factor receptors (FGFRs) are involved in several biological pathways and FGFR inhibitors may be useful in the treatment of squamous non-small cell lung cancer (Sq-NSCLC), FGFR aberrations are not well characterized in Sq-NSCLC. We comprehensively evaluated FGFR expression, fusions, and variants in 40 fresh-frozen primary Sq-NSCLC (stage IA3−IV) samples and tumor-adjacent normal tissues using real-time PCR and next-generation sequencing (NGS). Protein expression of FGFR1−3 and amplification of FGFR1 were also analyzed. FGFR1 and FGFR4 median gene expression was significantly (p < 0.001) decreased in tumors compared with normal tissue. Increased FGFR3 expression enhanced the recurrence risk (hazard ratio 4.72, p = 0.029), while high FGFR4 expression was associated with lymph node metastasis (p = 0.036). Enhanced FGFR1 gene expression was correlated with FGFR1 protein overexpression (r = 0.75, p = 0.0003), but not with FGFR1 amplification. NGS revealed known pathogenic FGFR2,3 variants, an FGFR3::TACC3 fusion, and a novel TACC1::FGFR1 fusion together with FGFR1,2 variants of uncertain significance not previously reported in Sq-NSCLC. These findings expand our knowledge of the Sq-NSCLC molecular background and show that combining different methods increases the rate of FGFR aberrations detection, which may improve patient selection for FGFRi treatment.

The JIPANG study is a randomized phase III study of pemetrexed/cisplatin (Pem/Cis) versus vinorelbine/cisplatin (Vnr/Cis) for completely resected stage II-IIIA non-squamous non-small cell lung cancer (Ns-NSCLC). This study did not meet the primary endpoint (recurrence-free survival, RFS) but Pem/Cis had a similar efficacy to Vnr/Cis with a better tolerability. Tumor mutation burden (TMB) is thought to have a predictive value of immune checkpoint inhibitors. However, the relevance of TMB to cytotoxic chemotherapy remains unknown. This exploratory study investigates the relationship between tumor mutation profiles and clinical outcome of Pem/Cis. Formalin-fixed, paraffin-embedded tumor tissues (n = 389) were obtained from the patients. Mutation status of tissue DNA was analyzed by targeted deep sequencing. Epidermal growth factor receptor (EGFR) mutations were detected frequently in Ns-NSCLC (139/374). Patients without any EGFR mutations experienced longer RFS in the Pem/Cis arm versus Vnr/Cis arms. Pem/Cis in patients with high TMB (≥12-16 mut/Mb) tended to have improved survival. In patients with wild-type EGFR, TMB ≥ 12 mut/Mb was significantly associated with improved RFS with Pem/Cis versus Vnr/Cis (not reached vs 52.5 months; hazard ratio (HR) 0.477). It could be proposed that TMB was predictive of RFS benefit with Pem/Cis versus Vnr/Cis in Ns-NSCLC. Further investigation is required to determine whether TMB combined with EGFR mutation status could be used as a predictive biomarker.

BACKGROUND: Squamous cell carcinoma (SCC) is a main pathological type of non-small cell lung cancer. It is common among elderly patients with poor prognosis. We aimed to establish an accurate nomogram to predict survival for elderly patients (≥ 60 years old) with SCC based on the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: The gerontal patients diagnosed with SCC from 2010 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. The independent prognostic factors were identified using multivariate Cox proportional hazards regression analysis, which were utilized to conduct a nomogram for predicting survival. The novel nomogram was evaluated by Concordance index (C-index), calibration curves, net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA). RESULTS: 32,474 elderly SCC patients were included in the analysis, who were randomly assigned to training cohort (n = 22,732) and validation cohort (n = 9742). The following factors were contained in the final prognostic model: age, sex, race, marital status, tumor site, AJCC stage, surgery, radiation and chemotherapy. Compared to AJCC stage, the novel nomogram exhibited better performance: C-index (training group: 0.789 vs. 0.730, validation group: 0.791 vs. 0.733), the areas under the receiver operating characteristic curve of the training set (1-year AUC: 0.846 vs. 0.791, 3-year AUC: 0.860 vs. 0.801, 5-year AUC: 0.859 vs. 0.794) and the validation set (1-year AUC: 0.846 vs. 0.793, 3-year AUC: 0.863 vs. 0.806, 5-year AUC: 0.866 vs. 0.801), and the 1-, 3- and 5-year calibration plots. Additionally, the NRI and IDI and 1-, 3- and 5-year DCA curves all confirmed that the nomogram was a great prognosis tool. CONCLUSIONS: We constructed a novel nomogram that could be practical and helpful for precise evaluation of elderly SCC patient prognosis, thus helping clinicians in determining the appropriate therapy strategies for individual SCC patients.

PURPOSE: Cisplatin-pemetrexed is the first-line chemotherapy for advanced, metastatic non-squamous non-small cell lung cancer (NSCLC), but the risk of kidney toxicity limits the therapeutic schedule. We performed a retrospective study of patient survival at 1 year and glomerular filtration rate (GFR) outcomes in cisplatin-pemetrexed-treated NSCLC patients. METHODS: Patients (P) treated for NSCLC between 2008 and 2014 were divided into two groups according to GFR at diagnosis: G1 (GFR ≥ 90 mL/min/1.73 m2) and G2 (GFR between 60 and 89 mL/min/1.73 m2). GFR were compared in the two groups at 3 and 12 months. The following statistical methods were used: multivariate generalized estimating equation model for GFR outcome, Kaplan-Meier method for patient survival rate, and Cox model for analysing survival criteria. RESULTS: A total of 112 patients were included in the study (G1 = 87 P, G2 = 25 P). At 12 months, mean GFR significantly decreased by 28.4 mL/min/1.73 m2 (- 22.3%, p = 0.001) in G1 and. 13.8 mL/min/1.73 m2 (- 17.2%, p = 0.001) in G2. Median patient survival was 9.6 months (1.1-52.4) in G1 and 19.7 months (3.7-56.9) in G2. A better overall survival was significantly correlated with GFR between 60 and 89 mL/min/1.73 m2 at diagnosis (p = 0.04), and higher cumulated doses of pemetrexed (p = 0.003) and cisplatin (p = 0.001). CONCLUSION: The better survival rate in G2 and its correlation with pemetrexed and cisplatin treatments suggest that, until other therapeutic choices become available, a cautious increase in dosage could be investigated as a way to improve poor prognoses.

BACKGROUND: Nivolumab has shown a survival benefit compared with docetaxel as second-line treatment for patients with previously treated advanced squamous non-small cell lung cancer (NSCLC) in a randomized phase III trial. The experiences of patients and physicians in routine clinical practice are often different from those in a controlled clinical trial setting. We present data from the entire Italian cohort of patients with squamous NSCLC enrolled in a worldwide nivolumab NSCLC expanded access program. PATIENTS AND METHODS: Patients with pretreated advanced squamous NSCLC received nivolumab 3 mg/kg every 2 weeks for up to 24 months. Safety was monitored throughout; efficacy data collected included objective tumor response, date of progression, and survival information. RESULTS: The Italian cohort comprised 371 patients who received at least one dose of nivolumab. In the overall population, the objective response rate (ORR) was 18%, the disease control rate (DCR) was 47%, and median overall survival (OS) was 7.9 months (95% confidence interval 6.2-9.6). In subgroup analyses, ORR, DCR, and median OS were, respectively, 17%, 48%, and 9.1 months in patients previously treated with two or more lines of therapy (n = 209) and 8%, 40%, and 10.0 months in patients treated beyond disease progression (n = 65). In the overall population, the rate of any-grade and grade 3-4 adverse events was 29% and 6%, respectively. Treatment-related adverse events led to treatment discontinuation in 14 patients (5%). There were no treatment-related deaths. CONCLUSION: To date, this report represents the most extensive clinical experience with nivolumab in advanced squamous NSCLC in current practice outside the controlled clinical trial setting. These data suggest that the efficacy and safety profiles of nivolumab in a broad, real-world setting are consistent with those obtained in clinical trials. IMPLICATIONS FOR PRACTICE: Nivolumab is approved in the U.S. and Europe for the treatment of advanced non-small cell lung cancer (NSCLC) after failure of prior platinum-based chemotherapy. In this cohort of Italian patients with previously treated, advanced squamous NSCLC treated in a real-world setting as part of the nivolumab expanded access program, the efficacy and safety of nivolumab was consistent with that previously reported in nivolumab clinical trials.

BACKGROUND: There has been no study so far on gemcitabine continuous maintenance therapy targeting only squamous non-small-cell lung cancer (NSCLC) patients. This study aimed to assess the efficacy and safety of cisplatin plus gemcitabine followed by maintenance gemcitabine for chemotherapy- naïve Japanese patients with advanced squamous NSCLC. METHODS: The patients received 4 cycles of gemcitabine (1,000 mg/m2, days 1 and 8) and cisplatin (80 mg/m2, day 1) every 3 weeks, followed by gemcitabine alone as maintenance therapy every 3 weeks until disease progression or unacceptable toxicity. The primary end point of the study was progression-free survival (PFS) from the date of registration. RESULTS: From May 2013 to October 2018, 26 patients were enrolled, and 25 patients received ≥1 cycle of planned treatment. Eighteen patients (69.2%) received 4 cycles of cisplatin plus gemcitabine, and 16 patients (61.5%) received ≥1 cycle of maintenance gemcitabine. The median PFS from the date of registration was 5.3 months (95% CI 2.9-7.3 months). In 16 patients who received ≥1 cycle of maintenance gemcitabine, the median PFS from the date of maintenance gemcitabine initiation was 3.8 months (95% CI 2.3-5.2 months). Their median overall survival from the date of registration was 11.9 months (95% CI 7.5-26.5 months). During the maintenance therapy, adverse events (AEs) were mostly Common Terminology Criteria for AE grade 1. CONCLUSIONS: While this trial did not meet the primary endpoint, the sufficient efficacy and feasibility of gemcitabine maintenance therapy were suggested.

OBJECTIVE: To evaluate the efficacy and safety profile of first-line bevacizumab (Bev)-containing pemetrexed-platinum chemotherapy in a real-world Chinese cohort with advanced non-squamous non-small cell lung cancer (NS-NSCLC). METHODS: A total of 415 eligible patients with NS-NSCLC who received first-line pemetrexed-platinum chemotherapy at National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between February 2010 and September 2017 were reviewed retrospectively: 309 Bev(-) and 106 Bev(+) cases. Bev was administered at 7.5 mg/kg every 3 weeks in the Bev(+) group. To reduce the risk of a selection bias, a propensity score-matching (PSM) was conducted and 105 pairs of Bev(-) and Bev(+) cases were identified. RESULTS: The median duration of follow-up was 15.8 months. The median progression-free survival (PFS) was prolonged significantly in the Bev(+) group than in the Bev(-) group in overall (9.8vs. 7.8 months, P=0.006) and PSM pairs (9.8 vs. 6.6 months, P<0.001). Moreover, patients receiving maintenance therapy with pemetrexed plus Bev had longer PFS than those interrupted after induction chemotherapy, or those receiving mono-maintenance with pemetrexed (12.3vs. 4.8 vs. 8.6 months; P<0.001). Multivariate analyses revealed Bev to be one of the favorable prognostic factors for PFS, along with the predictor of maintenance therapy. CONCLUSIONS: First-line induction and maintenance therapy with Bev (7.5 mg/kg every 3 weeks) combined with pemetrexed-platinum chemotherapy was efficacious and superior to non-Bev chemotherapy in Chinese patients with advanced NS-NSCLC.
RESUMO
OBJECTIVES:: Never-smokers may be a distinct subgroup among patients with advanced non-small cell lung cancer, appearing to benefit less from immunotherapy than smokers. We report results from never-smokers enrolled in the Italian cohort of the nivolumab expanded access program in pre-treated patients with advanced squamous non-small cell lung cancer. MATERIALS AND METHODS:: Nivolumab (3 mg/kg every 2 weeks for ≤24 months) was available on physician request. Efficacy data included objective tumor response, date of progression, and survival information. Safety was monitored. RESULTS:: Overall, 371 patients received at least one dose of nivolumab, including 31 never-smokers (8%). Objective response rate, disease-control rate, and median overall survival were 23%, 45%, and 12.1 months (95% confidence interval: 3.7-20.4), respectively, in never-smokers, and 18%, 47%, and 7.9 months (95% confidence interval: 6.2-9.6), respectively, in the overall expanded access program population. Any-grade and grade 3-4 treatment-related adverse events were reported in 12 (39%) and 3 (10%) never-smokers, respectively, and in 109 (29%) and 21 (6%) patients, respectively, in the overall expanded access program population. Grade 3-4 treatment-related adverse events in non-smokers were increased transaminases (n = 2; 6%) and diarrhea (n = 1; 3%). Treatment-related adverse events led to treatment discontinuation in 4 non-smokers (17%) and in 26 patients (9%) overall. CONCLUSION:: Pre-treated never-smokers with advanced squamous non-small cell lung cancer in this Italian expanded access program demonstrated efficacy and safety that were consistent with those in the overall expanded access program population and clinical trials. These results suggest that a proportion of never-smoker patients with squamous non-small cell lung cancer may be responsive to immunotherapy. Other factors, such as the tumor mutational load and the status of programmed death-ligand 1, anaplastic lymphoma kinase, and epidermal growth factor receptor, might play a potential key role.

BACKGROUND: LUX-Lung 3 showed afatinib improved progression-free survival (PFS) compared with cisplatin plus pemetrexed in patients with epidermal growth factor receptor (EGFR) mutations. In this study, chemotherapy efficacy tended to differ between patients with Leu858Arg (L858R) point mutation and Exon 19 deletion (Del-19); PFS in L858R patients (8.1 months) was greater than in Del-19 patients (5.6 months). We investigated whether there is any difference in efficacy of cisplatin plus pemetrexed between Del-19 and L858R. METHODS: This study is a multicenter retrospective study. We reviewed medical records of patients who had received cisplatin plus pemetrexed as first line chemotherapy. Efficacies were evaluated between EGFR mutation status: Del-19 and L858R. Wild type cases were reference arm only, and not included in any statistical analysis. RESULTS: Among 304 patients, 78 (25.7%) harbored EGFR mutations: Del-19 (36/78 patients, 46.2%); and L858R (42/78, 53.8%). Median PFS of L858R group (9.4 months, 95% confidence interval [CI]: 7.0-12.6) was significantly longer than Del-19 group (5.5 months, 95% CI, 3.6-8.6) (p = 0.049). Response rate (RR) and OS presented no significant difference between L858R and Del-19. In multivariate analysis, EGFR mutation status (L858R versus Del-19) was the only significant factor for longer PFS (Hazard ratio [HR]: 0.78, 95% CI: 0.62-0.98) (p = 0.033). CONCLUSION: Our study indicated better efficacy of cisplatin plus pemetrexed in L858R than in Del-19 patients. In EGFR-mutant NSCLC, EGFR-TKIs are undoubtedly the premier therapy. However, in second line or later settings, cisplatin plus pemetrexed regimen may confer higher efficacy for L858R patients.

Background: Randomized controlled trial to evaluate synergy between taxane plus platinum chemotherapy and CADI-05, a Toll like receptor-2 agonist targeting desmocollin-3 as a first-line therapy in advanced non-small-cell lung cancer (NSCLC). Patients and methods: Patients with advanced NSCLC (stage IIIB or IV) were randomized to cisplatin-paclitaxel (chemotherapy group, N = 112) or cisplatin-paclitaxel plus CADI-05 (chemoimmunotherapy group, N = 109). CADI-05 was administered a week before chemotherapy and on days 8 and 15 of each cycle and every month subsequently for 12 months or disease progression. Overall survival was compared using a log-rank test. Computed tomography was carried out at baseline, end of two cycles and four cycles. Response rate was evaluated using Response Evaluation Criteria in Solid Tumors criteria by an independent radiologist. Results: As per intention-to-treat analysis, no survival benefit was observed between two groups [208 versus 196 days; hazard ratio, 0.86; 95% confidence interval (CI) 0.63-1.19; P = 0.3804]. In a subgroup analysis, improvement in median survival by 127 days was observed in squamous NSCC with chemoimmunotherapy (hazard ratio, 0.55; 95% CI 0.32-0.95; P = 0.046). In patients receiving planned four cycles of chemotherapy, there was improved median overall survival by 66 days (299 versus 233 days; hazard ratio, 0.64; 95% CI 0.41 to 0.98; P = 0.04) in the chemoimmunotherapy group compared with the chemotherapy group. This was associated with the improved survival by 17.48% at the end of 1 year, in the chemoimmunotherapy group. Systemic adverse events were identical in both the groups. Conclusion: There was no survival benefit with the addition of CADI-05 to the combination of cisplatin-paclitaxel in patients with advanced NSCLC; however, the squamous cell subset did demonstrate a survival advantage.

BACKGROUND: Immunotherapy can become a crucial therapeutic option to improve the prognosis of patients with non-small-cell lung cancer (NSCLC). Here, we evaluated the impact of programmed cell death ligand-1 (PD-L1) expression in surgically resected NSCLCs. METHODS: We estimated PD-L1 expression in 229 consecutive NSCLC specimens using rabbit polyclonal antibodies to human PD-L1 in a SP263 immunohistochemical assay and evaluated PD-L1 expression for potential associations with clinicopathological parameters and survival time. RESULTS: PD-L1 expression was significantly higher in tumors from men or current smokers. Squamous cell carcinoma histology was independently associated with high PD-L1 expression according to multivariate analysis (p = 0.015). The 5-year survival rate of patients was 70%, and the difference in the 5-year survival rate according to PD-L1 expression was not statistically significant (high expression group [67%] vs. low expression group [68%]); however, the squamous cell carcinoma group exhibited significantly lower 5-year survival rates as compared to the non-squamous cell carcinoma group (53 and 71%, respectively; p = 0.026). CONCLUSION: Here, we revealed high PD-L1 expression and poor prognosis observed in patients with surgically resected squamous NSCLC as compared with non-squamous NSCLC. Our results support the identification of patient subsets that most likely respond to anti-PD-1 therapy as the first step in precision medicine.

Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer. Methods In this phase II trial, chemotherapy-naïve patients with squamous cell lung cancer were enrolled to induction therapy with four cycles of carboplatin (at an area under the curve of 5 on day 1) and S-1 (80 mg/m(2)/day on days 1-14) in a 28-day cycle. Patients who achieved disease control after induction therapy received maintenance therapy with S-1 in a 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival after administration of maintenance therapy. Results Fifty-one patients were enrolled in the study. The median progression-free survival from the start of maintenance therapy was 3.0 months (95 % confidence interval, 2.5-3.5). The most common toxicities associated with maintenance therapy were anemia, thrombocytopenia, and fatigue, but they were not severe. Conclusion S-1 maintenance therapy might be a feasible treatment option in patients with squamous cell lung cancer.

BACKGROUND: According to the results of the KEYNOTE-407 trial, pembrolizumab plus platinum-based chemotherapy is the standard of care for patients with previously untreated advanced squamous non-small-cell lung cancer (NSCLC). Ubenimex, a potent aminopeptidase inhibitor, is an oral drug with immunostimulatory and antitumor activities. We aim to assess the safety and efficacy of ubenimex in combination with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. PATIENTS AND METHODS: This prospective, single-arm, multicenter, phase II clinical trial is conducted to confirm the tolerability and efficacy of the tested drugs. Patients with previously untreated advanced squamous NSCLC will receive a predetermined daily dose of ubenimex orally plus 4 cycles of pembrolizumab, nab-paclitaxel, and carboplatin, followed by continuous administration of ubenimex and pembrolizumab for a maximum of 2 years. To confirm tolerability, the daily dose of ubenimex will begin at level 1 (30 mg), which will be increased to levels 2 (60 mg) and 3 (120 mg) according to the escalation criteria, with a standard 3 + 3 design for achieving the target dose-limiting toxicity rate of 33%. The efficacy, safety, and tolerability of ubenimex at the determined dose level will be analyzed. The primary endpoint of the efficacy evaluation will be the objective response rate assessed by an independent review committee. CONCLUSIONS: This is the first study to evaluate the efficacy and safety of ubenimex combined with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. The results will help devise future treatment strategies.
