RESUMEN
BACKGROUND: ALK tyrosine kinase inhibitors (TKIs) have revolutionized the treatment and largely improved the survival outcomes of patients with NSCLC harboring ALK rearrangements. Different ALK TKI compounds have demonstrated antitumor activity in these patients and are available in clinical practice. However, clinical expertise across countries varies according to local regulatory approval of different drugs, identifying multiple treatment scenarios to comply with international guidelines and clinical practice. METHODS: A virtual webinar was held on July 2023 to discuss the state of the art and future perspectives in the treatment of ALK rearrangement in advanced NSCLC in Italy. The faculty hosting the webinar was composed of eight medical oncologists from different regions of Italy with clinical expertise in treating patients with lung cancer. Live-shared notes were used to produce a report to serve as the basis of a review manuscript on the topic. RESULTS: Alectinib and brigatinib are the preferred front-line treatment options in Italy, pending approval of the front-line medicine lorlatinib, which would be considered among the choices. Due to a local regulatory limitation of second-line lorlatinib, which is not allowed after front-line brigatinib, alectinib is commonly the preferred front-line choice to follow a sequence of alectinib, followed by lorlatinib, followed by platinum plus pemetrexed chemotherapy. Age and performance status were not considered per se as clinical features influencing treatment choice. However, treatment compliance is deemed a relevant factor in decision making with regard to the number of pills to be administered. In general, given the availability of alternative choices, the spectrum of patients' comorbidities and polypharmacotherapy interactions should be taken into account in treatment selection according to the toxicity profile of each compound. In addition, several issues were debated with regard to improving treatment outcomes, including testing, brain metastases, and management of an oligoprogressive disease. CONCLUSIONS: The treatment scenario of ALK-positive disease is dynamically evolving. Furthermore, not all FDA- and EMA-approved compounds are approved in Italy with the same indications. This influences therapeutic opportunities and increases the need for greater clinical expertise to help and guide treatment selection.

INTRODUCTION: Brigatinib is a potent next-generation ALK tyrosine kinase inhibitor approved for treatment-naive and crizotinib-refractory advanced ALK-positive (ALK+) NSCLC. We evaluated brigatinib after other next-generation ALK tyrosine kinase inhibitors. METHODS: In this single-arm, phase 2, ALK in Lung Cancer Trial of brigAtinib-2 (NCT03535740), patients with advanced ALK+ NSCLC whose disease progressed on alectinib or ceritinib received brigatinib 180 mg once daily (after 7-d 90-mg lead-in). Primary end point was independent review committee (IRC)-assessed overall response rate (ORR). Circulating tumor DNA (ctDNA) was analyzed. RESULTS: Among 103 patients (data cutoff: September 30, 2020; median follow-up [range]: 10.8 [0.5-17.7] mo), confirmed IRC-ORR was 26.2% (95% confidence interval [CI]: 18.0-35.8), median duration of response, 6.3 months (95% CI: 5.6-not reached), and median progression-free survival (mPFS), 3.8 months (95% CI: 3.5-5.8). mPFS was 1.9 months (95% CI: 1.8-3.7) in patients with ctDNA-detectable baseline ALK fusion (n = 64). Among 86 patients who progressed on alectinib, IRC-ORR was 29.1% (95% CI: 19.8-39.9); mPFS was 3.8 months (95% CI: 1.9-5.4). Resistance mutations were present in 33.3% (26 of 78) of baseline ctDNA; 54% (14 of 26) of mutations were G1202R; 52% (33 of 64) of patients with detectable ALK fusion had EML4-ALK variant 3. Most common all-grade treatment-related adverse events were increased creatine phosphokinase (32%) and diarrhea (27%). The mean dose intensity of brigatinib (180 mg once daily) was 85.9%. CONCLUSIONS: In ALK in Lung Cancer Trial of brigAtinib-2, brigatinib was found to have a limited activity in patients with ALK+ NSCLC post-ceritinib or post-alectinib therapy. mPFS was longer with brigatinib in patients without baseline detectable plasma ALK fusion.

Introduction: ALK rearrangement is the only druggable oncogenic driver detectable by immunohistochemistry (IHC) not requiring further confirmation of positivity in accessing first-line specific inhibitors. ALK-positive patients experience clinical benefit from pemetrexed-based chemotherapy possibly due to lower thymidylate synthase (TS) levels. This study assesses agreement with three different ALK IHC clones in 37 FISH-positive NSCLC. TS expression by real time (RT)-PCR was compared with ALK FISH-negative cases. Materials and methods: 37 ALK FISH-positive NSCLC cases diagnosed between 2010 and 2015 in 7 Italian centres were investigated with ICH using three different anti-ALK antibodies (ALK1, 5A4 and D5F3). Staining for ALK1 and 5A4 was graded as 0+,1+,2+, and 3+, while the scoring for D5F3 was recorded as negative or positive. Proportion agreement analysis was done using Cohen's unweighted kappa (k). TS and ß-actin expression levels were analysed by quantitative RT-PCR. Comparison between TS expression in ALK FISH-positive specimens and a control cohort of ALK FISH-negative ones was performed with the Mann-Whitney and Kruskal-Wallis tests. Results: Considering 2+ and 3+ as positive, the proportion of IHC agreement was 0.1691 (95% CI 0-0.4595) for ALK1/5A4, 0.1691 (95% CI 0-0.4595) for ALK1/D5F3, and 1 for D5F3/5A4. Considering 3+ as positive, it was 0.1543 (95% CI 0-0.4665) for ALK1/ 5A4, 0.0212 (95% CI 0-0.1736) for ALK1/D5F3, and 0.2269 (95% CI 0-0.5462) for 5A4/D5F3. Median TS expression was 6.07 (1.28-14.94) and ALK-positive cases had a significant lower TS expression than ALK-negative tumours (p = 0.002). Conclusions: IHC proved to be a reliable tool for the diagnosis of ALK-rearranged NSCLC. D5F3 and 5A4 clones have the highest percentage of agreement. TS levels are significantly lower in FISH-positive patients.

Family history of cancer (FHC) is a hallmark of cancer risk and an independent predictor of outcome, albeit with uncertain biologic foundations. We previously showed that FHC-high patients experienced prolonged overall (OS) and progression-free survival (PFS) following PD-1/PD-L1 checkpoint inhibitors. To validate our findings in patients with NSCLC, we evaluated two multicenter cohorts of patients with metastatic NSCLC receiving either first-line pembrolizumab or chemotherapy. From each cohort, 607 patients were randomly case-control matched accounting for FHC, age, performance status, and disease burden. Compared to FHC-low/negative, FHC-high patients experienced longer OS (HR 0.67 [95% CI 0.46-0.95], p = 0.0281), PFS (HR 0.65 [95% CI 0.48-0.89]; p = 0.0074) and higher disease control rates (DCR, 86.4% vs 67.5%, p = 0.0096), within the pembrolizumab cohort. No significant associations were found between FHC and OS/PFS/DCR within the chemotherapy cohort. We explored the association between FHC and somatic DNA damage response (DDR) gene alterations as underlying mechanism to our findings in a parallel cohort of 118 NSCLC, 16.9% of whom were FHC-high. The prevalence of ≥ 1 somatic DDR gene mutation was 20% and 24.5% (p = 0.6684) in FHC-high vs. FHC-low/negative, with no differences in tumor mutational burden (6.0 vs. 7.6 Mut/Mb, p = 0.6018) and tumor cell PD-L1 expression. FHC-high status identifies NSCLC patients with improved outcomes from pembrolizumab but not chemotherapy, independent of somatic DDR gene status. Prospective studies evaluating FHC alongside germline genetic testing are warranted.

Epidermal growth factor receptor (EGFR) exon 20 insertions occur rarely among different cancer types, with the highest frequency reported among non-small-cell lung cancer (NSCLC) patients, particularly adenocarcinomas (ADCs). Exon 20 insertions fall back in the tyrosine kinase domain, and can be clustered into two principal groups represented by in frame insertions and three to 21 bp (corresponding to 1-7 amino acids) duplications within amino acids 762 and 774. The identification of these alterations is key for an adequate management of NSCLC patients due to the possibility to treat these patients with specific targeted therapies. Next generation sequencing (NGS) technology, able to detect several hotspot gene mutations for different patients simultaneously, is the best detection approach due to its higher sensitivity and specificity compared to other techniques. Here we reviewed the principal biological characteristics, the main detection technologies and treatment options for NSCLC patients harbouring EGFR exon 20 insertions.

BACKGROUND: Improved outcome in tobacco smoking patients with non-small cell lung cancer (NSCLC) following immunotherapy has previously been reported. However, little is known regarding this association during first-line immunotherapy in patients with high PD-L1 expression. In this study we compared clinical outcomes according to the smoking status of two large multicenter cohorts. METHODS: We compared clinical outcomes according to the smoking status (never smokers vs. current/former smokers) of two retrospective multicenter cohorts of metastatic NSCLC patients, treated with first-line pembrolizumab and platinum-based chemotherapy. RESULTS: A total of 962 NSCLC patients with PD-L1 expression ≥50% who received first-line pembrolizumab and 462 NSCLC patients who received first-line platinum-based chemotherapy were included in the study. Never smokers were confirmed to have a significantly higher risk of disease progression (hazard ratio [HR] = 1.49 [95% CI: 1.15-1.92], p = 0.0022) and death (HR = 1.38 [95% CI: 1.02-1.87], p = 0.0348) within the pembrolizumab cohort. On the contrary, a nonsignificant trend towards a reduced risk of disease progression (HR = 0.74 [95% CI: 0.52-1.05], p = 0.1003) and death (HR = 0.67 [95% CI: 0.45-1.01], p = 0.0593) were reported for never smokers within the chemotherapy cohort. After a random case-control matching, 424 patients from both cohorts were paired. Within the matched pembrolizumab cohort, never smokers had a significantly shorter progression-free survival (PFS) (HR = 1.68 [95% CI: 1.17-2.40], p = 0.0045) and a nonsignificant trend towards a shortened overall survival (OS) (HR = 1.32 [95% CI: 0.84-2.07], p = 0.2205). On the contrary, never smokers had a significantly longer PFS (HR = 0.68 [95% CI: 0.49-0.95], p = 0.0255) and OS (HR = 0.66 [95% CI: 0.45-0.97], p = 0,0356) compared to current/former smoker patients within the matched chemotherapy cohort. On pooled multivariable analysis, the interaction term between smoking status and treatment modality was concordantly statistically significant with respect to ORR (p = 0.0074), PFS (p = 0.0001) and OS (p = 0.0020), confirming the significantly different impact of smoking status across the two cohorts. CONCLUSIONS: Among metastatic NSCLC patients with PD-L1 expression ≥50% receiving first-line pembrolizumab, current/former smokers experienced improved PFS and OS. On the contrary, worse outcomes were reported among current/former smokers receiving first-line chemotherapy.

OBJECTIVES: Randomized controlled trials have demonstrated that afatinib is a suitable treatment option for patients with epidermal growth factor receptor mutation-positive (EGFRm +) non-small cell lung cancer (NSCLC). However, such studies often exclude patients treated in routine clinical practice. We report interim results from a Phase 3b, open-label, multicenter, single-arm, exploratory trial, in which afatinib was investigated in a real-world setting. MATERIALS AND METHODS: Patients with EGFRm + tyrosine kinase inhibitor (TKI)-naïve NSCLC received afatinib 40 mg orally, once-daily, until disease progression, or voluntary withdrawal. Primary objective was safety. RESULTS: Overall, 479 patients received afatinib: median age 65 years, 8 % of patients had an ECOG performance status ≥ 2, 17 % had brain metastases, and 13 % had tumors containing uncommon mutations only. All but one patient (99.8 %) had an adverse event (AE). Treatment-related AEs (TRAEs; any/grade ≥ 3) occurred in 97 %/44 % of patients; most common were diarrhea (87 %/16 %) and rash (51 %/11 %). AEs leading to afatinib dose-reduction were reported in 258 patients (54 %), and 37 patients (8 %) discontinued treatment due to a TRAE. Objective response rate was 45.5 %, median duration of response was 14.1 months (95 % CI: 12.2-16.4). Overall median time to symptomatic progression and progression-free survival were 14.9 months (95 % CI: 13.8-17.6) and 13.4 months (95 % CI: 11.8-14.5), respectively, in the overall population and 19.3 months (95 % CI: 15.6-21.8) and 15.9 months (95 % CI: 13.9-19.1) in patients with EGFR exon 19 deletions. CONCLUSIONS: Afatinib administration in routine clinical practice was well tolerated with no new safety signals and demonstrated promising efficacy in patients with EGFRm + NSCLC. TRAEs were generally manageable with tolerability-guided dose reductions. Overall, these data independently support findings from randomized controlled trials of afatinib in EGFRm + NSCLC.

Aim: Patient-reported symptoms, functioning and overall quality of life (QoL) were compared between dacomitinib and gefitinib in ARCHER 1050. Patients & methods: Patients (n = 448) with advanced EGFR mutation-positive non-small-cell lung cancer completed the EORTC-QLQ-C30 questionnaire and its lung-specific module, LC-13. Mean scores over time were analyzed using a mixed model for repeated measures. Results: Both treatments showed early improvement in disease-related symptoms that was maintained during treatment. Treatment-related diarrhea and sore mouth decreased following dose reduction with dacomitinib. There were no clinically meaningful changes in functioning and overall QoL in either treatment group. Conclusion: Longer treatment duration, enabled by dose reduction, allowed patients on dacomitinib to improve treatment-related symptoms and maintain functioning and overall QoL for longer than gefitinib.

BACKGROUND: ARCHER 1050, an ongoing, randomized, open-label, phase III trial of dacomitinib versus gefitinib in newly diagnosed patients with advanced non-small-cell lung cancer (NSCLC) and an EGFR-activating mutation, reported significant improvement in overall survival (OS) with dacomitinib. OBJECTIVE: This paper reports an updated OS analysis of ARCHER 1050 after an extended follow-up. PATIENTS AND METHODS: In this multinational, multicenter trial, adults (aged ≥ 18 years or ≥ 20 years in Japan and Korea) with newly diagnosed NSCLC and EGFR mutation (exon 19 deletion or exon 21 L858R substitution), and no history of central nervous system metastases, were randomized 1:1 to receive dacomitinib 45 mg/day (n = 227) or gefitinib 250 mg/day (n = 225). Randomization was stratified by race and EGFR mutation type. An ad hoc updated analysis of OS was conducted at the protocol-defined cut-off of 48 months from first dosing of the last enrolled patient (13 May 2019). RESULTS: After a median follow-up of 47.9 months, 133 (58.6%) patients had died in the dacomitinib arm and 152 (67.6%) in the gefitinib arm. The hazard ratio (HR) for OS was 0.748 (95% CI 0.591-0.947; two-sided P = 0.0155); median OS was 34.1 months with dacomitinib versus 27.0 months with gefitinib. The HR for OS in patients with dose reduction(s) in the dacomitinib arm (n = 154) compared with all patients in the gefitinib arm was 0.554 (95% CI 0.420-0.730); median OS was 42.5 months for patients with dose reduction(s) in the dacomitinib arm. The most common adverse events were diarrhea (87.7%), paronychia (61.7%), dermatitis acneiform (49.3%), and stomatitis (43.6%) with dacomitinib, and diarrhea (55.8%) and alanine aminotransferase increased (40.2%) with gefitinib. CONCLUSIONS: The OS benefit from first-line treatment with dacomitinib versus gefitinib was maintained after extended follow-up in patients with advanced NSCLC with EGFR-activating mutations.

Lung cancer is a disease extremely heterogeneous in the molecular aspect and knowing the mutational profile of patients is essential in order to initiate the most appropriate treatment. In 2018, alectinib was approved in Italy for the first-line treatment of patients with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC), becoming a new therapeutic option for this patient group which constitutes approximately 3-7% of patients with NSCLC. On October 26th a virtual meeting was held in which 10 clinicians from various oncology centers in Lazio took part on the management of therapy of patients with Alk translocation, directed by Dr. Maria Rita Migliorino. The aim of the meeting was to share their clinical experience and to provide a series of practical that can help clinicians during treatment with target therapies in ALK-positive NSCLC.

BACKGROUND: Pembrolizumab is the first-line standard of care for advanced non-small cell lung cancer (NSCLC) with a PD-L1 tumour proportion score (TPS) ≥ 50%. Eastern Cooperative Oncology Group performance status (PS) 2 patients may receive pembrolizumab, despite the absence of sustaining evidence. PATIENTS AND METHODS: GOIRC-2018-01 is a multicentre, retrospective, observational study. PS 2 NSCLC patients with a PD-L1 TPS ≥50% receiving first-line pembrolizumab from June 2017 to December 2018 at 21 Italian institutions were included. Clinical-pathological characteristics were correlated with disease response and survival outcomes; adverse events were recorded. The primary objective was 6-months progression-free rate (6-months PFR). RESULTS: One hundred fifty-three patients (median age 70 years) were enrolled. At a median follow-up of 18.2 months, median progression-free survival (PFS) and overall survival (OS) were 2.4 (95% confidence interval, 95% CI, 1.6-2.5) and 3.0 months (95% CI 2.4-3.5), respectively. 6-months PFR was 27% (95% CI 21-35%). Patients with a PS 2 determined by comorbidities (n = 41) had significantly better outcomes compared with disease burden-induced PS 2 (n = 112). Indeed, 6-months PFR was 49% versus 19%, median PFS 5.6 versus 1.8 months and OS 11.8 versus 2.8 months, respectively. Additional potential prognostic factors (radiotherapy, antibiotics, steroids received before pembrolizumab) correlated with clinical outcomes. The determinant of PS 2 resulted the only factor independently impacting on both PFS and OS. No toxicity issues emerged. CONCLUSIONS: Outcomes of PS 2 NSCLC patients with PD-L1 TPS ≥50% receiving first-line pembrolizumab were globally dismal but strongly dependent on the reason conditioning the poor PS itself.

Background: We investigate the role of family history of cancer (FHC) and diagnosis of metachronous and/or synchronous multiple neoplasms (MN), during anti-PD-1/PD-L1 immunotherapy. Design: This was a multicenter retrospective study of advanced cancer patients treated with anti-PD-1/PD-L1 immunotherapy. FHC was collected in lineal and collateral lines, and patients were categorized as follows: FHC-high (in case of cancer diagnoses in both the lineal and collateral family lines), FHC-low (in case of cancer diagnoses in only one family line), and FHC-negative. Patients were also categorized according to the diagnosis of MN as follows: MN-high (>2 malignancies), MN-low (two malignancies), and MN-negative. Objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and incidence of immune-related adverse events (irAEs) of any grade were evaluated. Results: 822 consecutive patients were evaluated. 458 patients (55.7%) were FHC-negative, 289 (35.2%) were FHC-low, and 75 (9.1%) FHC-high, respectively. 29 (3.5%) had a diagnosis of synchronous MN and 94 (11.4%) of metachronous MN. 108 (13.2%) and 15 (1.8%) patients were MN-low and MN-high, respectively. The median follow-up was 15.6 months. No significant differences were found regarding ORR among subgroups. FHC-high patients had a significantly longer PFS (hazard ratio [HR] = 0.69 [95% CI: 0.48-0.97], p = .0379) and OS (HR = 0.61 [95% CI: 0.39-0.93], p = .0210), when compared to FHC-negative patients. FHC-high was confirmed as an independent predictor for PFS and OS at multivariate analysis. No significant differences were found according to MN categories. FHC-high patients had a significantly higher incidence of irAEs of any grade, compared to FHC-negative patients (p = .0012). Conclusions: FHC-high patients seem to benefit more than FHC-negative patients from anti-PD-1/PD-L1 checkpoint inhibitors.

BACKGROUND: Several studies have found an association between higher body mass index (BMI) and improved clinical outcomes in cancer patients receiving programmed cell death protein-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) checkpoint inhibitors. In a previous study, we found that overweight/obese patients were significantly more likely to experience any grade immune-related adverse events (irAEs) compared to non-overweight patients. PATIENTS AND METHODS: We conducted a 'real-life', multi centre, retrospective observational study aimed at comparing the incidence of irAEs among cancer patients treated with PD-1/PD-L1 inhibitors according to baseline BMI. RESULTS: One thousand and seventy advanced cancer patients were evaluated. The median age was 68 years (range: 21-92), male/female ratio was 724/346. Primary tumours were: non-small-cell lung carcinoma (NSCLC) (653 patients), melanoma (233 patients), renal cell carcinoma (RCC) (152 patients) and others (29 patients). Median BMI was 25 (13.6-46.6); according to World Health Organisation (WHO) classification, 44 patients (4.1%) were defined as underweight, 480 patients (44.9%) as having a normal weight, 416 patients (38.9%) as overweight and 130 patients (12.1%) as obese. Higher BMI was significantly related to higher occurrence of any grade immune-related adverse events [irAEs] (p < 0.0001), G3/G4 irAEs (p < 0.0001) and irAEs leading to discontinuation (LTD) (p < 0.0001). Overweight and obesity were confirmed predictors for irAEs of any grade at both univariate and multivariate analysis. The adjusted odds ratios (ORs) (compared to normal-weight) were 10.6; 95% confidence interval (95%CI): 7.5-14.9 for overweight, and 16.6 (95%CI: 10.3-26.7) for obese patients. Obesity was the only factor significantly related to a higher incidence of G3/G4 irAEs (OR = 11.9 [95%CI: 6.4-22.3], p < 0.0001) and LTD irAEs (OR = 8.8 [95%CI: 4.3-18.2], p < 0.0001). Overweight and obese patients experienced a significantly higher occurrence of cutaneous, endocrine, gastro-intestinal (GI), hepatic and 'others' irAEs, compared to normal-weight patients. Only obese patients experienced a significantly higher occurrence of pulmonary and rheumatic irAEs, compared to normal-weight patients. CONCLUSIONS: Considering the previously evidenced association between higher BMI and better outcome, the current finding about the relationship between BMI and irAEs occurrence can contribute to consideration of these findings as the upside of the downside, which underlies an 'immunogenic phenotype'.

OBJECTIVES: Molecular diagnostics and care of non-small cell lung cancer (NSCLC) are continuously evolving. Few data document the current strategies to manage advanced NSCLC patients beyond progression in clinical practice. PATIENTS AND METHODS: Be-TeaM is an Italian multi-center observational study conducted on consecutive EGFR-mutated stage IV NSCLC patients, progressed during/after a first-line EGFR-TKI. It consists of a retrospective phase, from first-line EGFR-TKI therapy start until study entry (i.e. beginning of the diagnostic process), and a prospective phase, until treatment choice or for 3 months if no therapy was prescribed. Primary objective was to describe the diagnostic and therapeutic approaches adopted after progression in a real-world setting. RESULTS: Of 308 patients enrolled in 63 centers from July 2017 to June 2018, 289 were included in the analysis. In first line, 53.3 % received gefitinib, 32.5 % afatinib and 14.2 % erlotinib. The testing rate (i.e. rate of all patients undergone any biopsy -liquid and/or tissue- for the T790â¯M detection) was 90.7 %, with liquid biopsy being the most frequently executed. Of 262 biopsied patients, 64.5 % underwent only 1 liquid biopsy, 10.7 % only 1 tissue biopsy and 18.3 % >1 biopsy, both liquid and solid in 85.4 %. The T790M positivity rate was 45.3 %; of 166 patients undergone only a liquid biopsy and tested for the mutation, 39.8 % were T790M+ and 60.2 % T790M-/undetermined. By the observation end, 87.9 % patients had a post-progression treatment chosen, osimertinib being the most frequent among the T790M+. CONCLUSION: Be-TeaM provides the first snapshot of current practices for the management of NSCLC patients beyond progression in Italy; in clinical practice, assessing the T790M status is not always feasible.

BACKGROUND: Bone metastases (BoM) are a negative prognostic factor in non-small-cell lung cancer (NSCLC). Beyond its supportive role, bone is a hematopoietic organ actively regulating immune system. We hypothesized that BoM may influence sensitivity to immunotherapy. METHODS: Pretreated non-squamous (cohort A) and squamous (cohort B) NSCLCs included in the Italian Expanded Access Program were evaluated for nivolumab efficacy according to BoM. RESULTS: Cohort A accounted for 1588 patients with non-squamous NSCLC, including 626 (39%) with (BoM+) and 962 (61%) without BoM (BoM-). Cohort B accounted for 371 patients with squamous histology including 120 BoM+ (32%) and 251 (68%) BoM- cases. BoM+ had lower overall response rate (ORR; Cohort A: 12% versus 23%, p < 0.0001; Cohort B: 13% versus 22%, p = 0.04), shorter progression free survival (PFS; Cohort A: 3.0 versus 4.0 months, p < 0.0001; Cohort B: 2.7 versus 5.2 months, p < 0.0001) and overall survival (OS; Cohort A: 7.4 versus 15.3 months, p < 0.0001; Cohort B: 5.0 versus 10.9 months, p < 0.0001). Moreover, BoM negatively affected outcome irrespective of performance status (PS; OS in both cohorts: p < 0.0001) and liver metastases (OS cohort A: p < 0.0001; OS Cohort B: p = 0.48). At multivariate analysis, BoM independently associated with higher risk of death (cohort A: HR 1.50; cohort B: HR 1.78). CONCLUSIONS: BoM impairs immunotherapy efficacy. Accurate bone staging should be included in clinical trials with immunotherapy.

BACKGROUND/AIM: Brain metastases are an additional challenge in patients with non-small-cell lung cancer (NSCLC) because most chemotherapy agents cannot cross the blood-brain barrier. Nivolumab has demonstrated efficacy in patients with advanced squamous NSCLC, but because patients with central nervous system (CNS) metastases are typically excluded from registration trials, 'field-practice' data are needed. PATIENTS AND METHODS: Patients in the Italian cohort of the Expanded Access Program (EAP) who had CNS metastases at baseline were analyzed. RESULTS: Thirty-seven patients with CNS metastases received a median of six doses of nivolumab. Three patients (8%) had grade 3-4 adverse events and one patient discontinued due to an adverse event. The objective response rate was 19%. Median overall survival was 5.8 (95% confidence interval=1.9-9.8) months and median progression-free survival was 4.9 (95% confidence interval=2.7-7.1) months. CONCLUSION: The safety and efficacy of nivolumab in patients with CNS metastases appear to be similar to those seen in the overall EAP cohort in Italy.

OBJECTIVES: Despite the scant docetaxel's tolerability, second-line association with nintedanib still represents a standard-of-care for non-squamous non-small cell lung cancer (nsNSCLC), giving to rapidly-progressing patients the greatest survival advantage. The SENECA trial is a phase IIb, open-label, study evaluating whether nintedanib/docetaxel can be equally effective and safe regardless docetaxel schedule. MATERIALS AND METHODS: Recurrent nsNSCLC patients were stratified into cohort 1 and 2, according to relapse-time (within or over 3 months) from end of first-line chemotherapy. They were treated with docetaxel (T1: 33â¯mg/mq on days 1 and 8 in a 21-days cycle; T2: 75â¯mg/mq q3wks) plus nintedanib, allowing maintenance in case of disease-control. Primary endpoint was progression-free survival (PFS) by investigator's assessment; secondary endpoints: overall survival (OS), safety and quality-of-life. RESULTS: Between January 2016-April 2018, 212 patients were evaluated: 30 resulted screening-failures, 12 were excluded for lack of compliance. According to investigator's choice, 85 patients received T1 docetaxel and 85 T2; 138 (81.2%) were stratified in C1, 32 (18.8%) in C2, with a median relapse-time of 0.54 and 9.29 months, respectively. Baseline characteristics were balanced between groups. After 35.5 months follow-up, no survival differences appear between cohorts and treatments; toxicity seems to be slightly higher in T2, especially for chemotherapy-related events. Perception of quality-of-life remains stable and docetaxel schedule doesn't modify patients' load. CONCLUSION: The SENECA trial confirms efficacy of second-line nintedanib/docetaxel for nsNSCLC, regardless time of recurrence and docetaxel schedule; higher toxicities for q3wks docetaxel, without alterations in quality-of-life, have been described, underling the possibility, adopting the weekly schedule, to maintain efficacy with better tolerability.

Aim: We evaluated reasons for dacomitinib dose reduction (DR) and examined adverse event (AE) incidence, key efficacy end points (progression-free survival [PFS]/overall survival [OS]), and pharmacokinetics in dose-reducing patients in the ARCHER 1050 trial. Patients & methods: Newly diagnosed patients with EGFR mutation-positive, advanced non-small-cell lung cancer received oral dacomitinib (45 mg once-daily [QD]), with stepwise toxicity-managing DR (30 and 15 mg QD) permitted. Results: Skin toxicities (62.7%) were the most common DR-leading AEs. The AE incidence and severity decreased following DRs. Initial plasma dacomitinib exposure (45 mg QD) was generally lower in patients remaining at 45 mg QD compared with dose-reducing patients. Median PFS and OS were similar in all dacomitinib-treated patients and dose-reducing patients. Conclusion: Tolerability-guided dose modifications enabled patients to continue with dacomitinib and benefit from PFS/OS improvement. Trial registration number: NCT01774721.

BACKGROUND: Severe skin rash is listed among important side effects of EGFR tyrosine kinase inhibitors. Polydatin (PD), a glycosylated polyphenol, is endowed with anti-inflammatory activity in human epidermal keratinocytes. OBJECTIVE: This study evaluated the effect of topical application of a moisturizer containing PD to prevent skin rash in patients with mutated non-small cell lung cancer (NSCLC) treated with afatinib. MATERIALS AND METHODS: Eligible NSCLC patients with metastatic disease were treated with first-line afatinib 40 mg/die. One day before starting systemic therapy, all patients received topical administration of a 1.5% PD-based cream b.i.d. every day until the end of afatinib treatment. RESULTS: Out of 34 treated patients, the incidence of skin rash (all grades) was 41.2% and grade 2 rash was 20.6%, and grade 3 rash was not observed in any of the patients. None of the patients discontinued therapy for toxicity. The mean duration of treatment was 6.4 months, calculated from the time treatment was started to the date treatment was stopped. CONCLUSION: The results showed that a PD-based cream can reduce the incidence of grade ≥2 skin toxicities in patients treated with afatinib. Clinical study registration number: Prot. No. 130/CE Lazio 1 Italy.
RESUMEN
BACKGROUND: Immune-related adverse events (irAEs) developed during immunotherapy with anti-PD-1 agents, could be a predictive surrogate marker of clinical benefit in patients with advanced non-small-cell lung cancer (NSCLC). METHODS: Patients with NSCLC, treated with anti-PD-1 agents, were retrospectively evaluated. Univariate and multivariate analyses were performed to evaluate the relationships between types of irAEs (differentiated according to system/organ involved and to single-site/multiple-site), overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). We further performed a 6-week landmark analysis. RESULTS: A total of 559 patients were enrolled; 231 patients (41.3%) developed irAEs of any grade and 50 patients (8.9%) G3/G4 events; 191 of them (82.6%) developed "single-site" irAEs and 40 (17.4%) "multiple-site" irAEs. At multivariate analysis, higher ORR was related to irAEs of any grade (P < .0001), "single-site" irAEs (P < .0001), endocrine (P = .0043) and skin irAEs (P = .0005). Longer PFS was related to irAEs of any grade (P < .0001), "single-site" irAEs (P < .0001), "multiple-site" irAEs (P = .0374), endocrine irAEs (P = .0084) and skin irAEs (P = .0001). Longer OS was related to irAEs of any grade (P < .0001), "single-site" irAEs (P < .0001), endocrine irAEs (P = .0044), gastrointestinal irAEs (P = .0437), skin irAEs (P = .0006), and others irAEs (P = .0378). At the 6-week landmark analysis, irAEs of any grade was confirmed an independent predictor of higher ORR, longer PFS, and longer OS. CONCLUSION: Our study confirmed that irAEs are concordantly related to higher ORR, longer PFS, and longer OS with anti-PD-1 immunotherapy in patients with NSCLC.
