Background: The standard therapy for advanced stage non-small cell lung cancer (NSCLC) with no actionable gene alterations is a platinum-based chemotherapy doublet and immune checkpoint blocker (ICB), either concurrently or sequentially, followed by docetaxel at the time of tumor progression. However, more effective treatments are needed. We evaluated the nab -paclitaxel and durvalumab combination in patients with previously treated advanced stage NSCLC. Methods: Patients with advanced stage NSCLC previously treated with one line of platinum-based doublet with or without an ICB and no activating EGFR mutations or ALK translocations received nab -paclitaxel 100 mg/m 2 (days 1 and 8) plus durvalumab 1,125 mg (day 15) every 21 days. The primary endpoint was progression-free survival (PFS). Key secondary endpoints included overall survival (OS) and safety. Results: Between February 2016 and December 2016, 79 patients were enrolled. The median age was 63 years. Most patients were males (68.4%), had non-squamous histology (69.6%), and had no prior ICB treatment (88.6%). The median PFS was 4.5 months; median OS was 10.1 months. A post hoc analysis of survival by prior ICB treatment revealed a median PFS and OS of 4.4 and 9.9 months, respectively, in ICB-naive patients and 6.9 months and not estimable, respectively, in patients previously treated with ICB. The most common treatment-emergent adverse events were asthenia (46.2%) and diarrhea (34.6%); four treatment-related deaths (5.1%) occurred. Conclusions: The nab -paclitaxel and durvalumab combination is feasible and demonstrated antitumor activity without new safety signals. Additional studies using taxanes and ICB in patients with previously treated NSCLC are warranted. Clinical Trial Registration: ClinicalTrials.gov registration (NCT02250326).

IntroductionDespite improvements in the treatment of advanced non-small cell lung cancer (NSCLC), certain patient populations remain underrepresented in clinical trials. Many patients have benefited from platinum doublets, including nab-paclitaxel–based regimens, but there are patients with comorbidities who particularly require careful balancing of efficacy and safety. Clinical trial data are limited for patients who are elderly or have renal impairment, diabetes, or impaired performance status.MethodsTo better understand outcomes in these patient populations, we performed a pooled analysis using data from the ABOUND clinical trial program (ABOUND.SQM, ABOUND.PS2, ABOUND.70+) and the key phase III trial of nab-paclitaxel/carboplatin in advanced NSCLC. The populations included in this pooled analysis consisted of elderly patients (≥ 70 years) and patients with renal impairment (eGFR < 60 ml/min/1.73 m2), diabetes, or poor performance status (ECOG PS 2).ResultsMedian progression-free survival (PFS) ranged from 4.1 months in patients with ECOG PS 2 (95% CI, 2.04–5.09 months) to 7.7 months in patients with diabetes (95% CI, 5.88–10.12 months). PFS for elderly patients and patients with renal impairment was 6.9 months each (95% CI, 6.01–7.98 months and 4.47–9.79 months, respectively). Median overall survival (OS) was 18.2 months (95% CI, 10.94–28.22 months), 17.4 months (95% CI, 14.59–20.14 months), and 16.1 months (95% CI, 14.09–18.50 months) in patients with renal impairment, patients with diabetes, and elderly patients, respectively. Patients with ECOG PS 2 exhibited the shortest median OS: 5.6 months (95% CI, 3.98–11.37 months). Overall response rates were 56.9%, 54.6%, 45.9%, and 29.4% in patients with diabetes, elderly patients, patients with renal impairment, and patients with ECOG PS 2, respectively. Most treatment-related adverse events were hematologic. The most common grade 3/4 hematologic adverse events in patients with renal impairment, elderly patients, patients with diabetes, and patients with poor performance status included neutropenia, anemia, and thrombocytopenia.ConclusionsAlthough survival data in patients with ECOG PS 2 were notably inferior to the other cohorts, our findings are consistent with those previously reported in the population-specific studies of the ABOUND trials and lend additional support for the use of nab-paclitaxel–based regimens in historically understudied and vulnerable populations.
down-regulating Hsp90 client protein levels with acceptable in single-agent phase II solid studies. Furthermore, Hsp90 inhibition with ganetespib can enhance T-cell-mediated anti-tumor immune response. We present the MESO-02 trial of ganetespib plus pemetrexed and cisplatin/carboplatin in chemotherapy-naïve MPM patients. This novel combination was well-tolerated. We observed promising anti-tumor activity including partial responses, particularly in patients with epithelioid histology, and Loss of Heterozygosity was associated with shorter time to progression. Response rates of ganetespib are comparable or better than those observed in other novel-agent MPM trials. This study supports further investigation of ganetespib combination therapy to treat MPM in a large randomized controlled trial. ABSTRACT Purpose Ganetespib, a highly potent, small molecule Heatshock protein 90 inhibitor, has potential efficacy in malignant pleural mesothelioma (MPM) via activity on critical survival pathways and known synergies with antifolates and platinum chemotherapy. We conducted a dose-escalation study to identify the Maximum Tolerated Dose (MTD) of ganetespib in chemotherapy-naïve MPM patients. was a phase Ib trial of (100 , , ; and with pemetrexed ; and ; or carboplatin (area under concentration-time curve day in MPM patients.

AbstractPurpose: Ganetespib, a highly potent, small-molecule Heatshock protein 90 inhibitor, has potential efficacy in malignant pleural mesothelioma (MPM) via activity on critical survival pathways and known synergies with antifolates and platinum chemotherapy. We conducted a dose-escalation study to identify the maximum tolerated dose (MTD) of ganetespib in patients with chemotherapy-naïve MPM. Patients and Methods: MESO-02 (ClinicalTrials.gov: NCT01590160) was a nonrandomized, multicenter, phase Ib trial of 3-weekly ganetespib (100 mg/m2, 150 mg/m2, 200 mg/m2; days 1 and 15) with pemetrexed (500 mg/m2; day 1) and cisplatin (75 mg/m2; day 1) or carboplatin (area under concentration–time curve 5; day 1) in patients with MPM. Dose escalation was performed using the 3 + 3 design (cisplatin) and accelerated titration design (carboplatin). Secondary endpoints included best response, progression-free survival (PFS), and pharmacogenomic analyses. Results: Of 27 patients enrolled (cisplatin, n = 16; carboplatin, n = 11), 3 experienced dose-limiting toxicities: grade 3 nausea (cisplatin, n = 1; carboplatin, n = 1) and grade 2 infusion-related reaction (carboplatin, n = 1). Ganetespib's MTD was 200 mg/m2. Partial response was observed in 14 of 27 patients (52%; 61% in 23 response-evaluable patients) and 13 of 21 (62%) with epithelioid histology. At the MTD, 10 of 18 patients (56%) had partial response, 15 of 18 (83%) had disease control, and median PFS was 6.3 months (95% CI, 5.0–10.0). One responder exhibited disease control beyond 50 months. Global loss of heterozygosity was associated with shorter time to progression (HR 1.12; 95% CI, 1.02–1.24; P = 0.018). Conclusions: Ganetespib can be combined safely with pemetrexed and platinum chemotherapy to treat patients with MPM. This class of agent should be investigated in larger randomized studies.
Aim: Evaluate quality of life (QoL) in patients with advanced non-small cell lung cancer treated with second or third line nab-paclitaxel +/- durvalumab. Patients & methods: Longitudinal QoL was assessed using Lung Cancer Symptom Scale, EuroQoL Five-Dimensions Five-Levels and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core. Results: QoL was generally stable through eight treatment cycles (both arms). Clinically meaningful improvement from baseline was noted in Lung Cancer Symptom Scale (overall constitutional score and three-item index [nab-paclitaxel + durvalumab]) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item core (global health status/QoL and emotional functioning [both arms] and pain [nab-paclitaxel + durvalumab]) analyses. EuroQoL Five-Dimensions Five-Levels domains were stable/improved or completely resolved at least once in 19-56% and 9-51% of patients, respectively. Conclusion: While QoL trends were promising, additional data are required to support these regimens in this setting.
There is inconsistency among published guidelines for the optimal diagnostic and management pathways for patients with typical (TC) or atypical (AC) pulmonary carcinoid tumours. We conducted a UK-wide clinician survey to assess current practice for the diagnosis, management, and follow-up of patients with TC/AC and descriptively compared management between European Neuroendocrine Tumor Society (ENETS) accredited centres of excellence (CoE) and nonaccredited centres (non-CoE). Twenty-seven clinicians (10 CoE; 17 non-CoE) participated. Computed tomography of thorax, abdomen, and pelvis was the most commonly reported diagnostic tool (96% of respondents), and bone scans and gallium somatostatin receptor scintigraphy positron emission tomography (SRS PET) were the least commonly reported (30% and 37% of respondents, respectively). Adjuvant therapy is considered for resected TC/AC by <5% of respondents for patients with stage N0 M0 AC or TC, up to 48% of respondents for patients with AC with R1 disease. Somatostatin analogues were the most commonly reported first-line treatment (63% of respondents), and chemotherapy was the most commonly reported second-line therapy and third-line therapy (33% and 41%, respectively) for unresectable and metastatic disease. Reported frequency of initial follow-up after primary surgery ranged from every 2 months to annual, and total follow-up duration ranged from 2 years to indefinite depending on disease type (TC/AC) and stage. For most diagnostic investigations, the highest reported frequency of use was in CoE, most notably gallium SRS PET (70% CoE vs. 18% non-CoE respondents). 93% of respondents (100% CoE; 88% non-CoE) reported having neuroendocrine tumour- (NET-) specialist multidisciplinary team meetings at their centre; 59% (90% CoE; 41% non-CoE) had a NET Clinical Nurse Specialist (CNS) and 48% (80% CoE; 29% non-CoE) had a lung NET patient database. The survey results suggest variability between UK centres in diagnostic pathways and management of patients with TC/AC and suggest that CoE may be able to offer an improved service to patients.
Background The diagnosis of neuroendocrine neoplasms (NENs) is often delayed. This first UK population-based epidemiological study of NENs compares outcomes with non-NENs to identify any inequalities. Methods Age-standardised incidence rate (ASR), 1-year overall survival, hazard ratios and standardised mortality rates (SMRs) were calculated for all malignant NENs diagnosed 2013–2015 from UK national Public Health records. Comparison with non-NENs assessed 1-year overall survival (1YS) and association between diagnosis at stage IV and morphology. Results A total of 15,222 NENs were identified, with an ASR (2013–2015 combined) of 8.6 per 100,000 (95% CI 8.5–8.7); 4.6 per 100 000 (95% CI, 4.5–4.7) for gastro-entero-pancreatic (GEP) NENs. The 1YS was 75% (95% CI, 73.9–75.4) varying significantly by sex. Site and morphology were prognostic. NENs (predominantly small cell carcinomas) in the oesophagus, bladder, prostate, and female reproductive organs had a poorer outcome and were three times more likely to be diagnosed at stage IV than non-NENs. Conclusion Advanced stage at diagnosis with significantly poorer outcomes of some NENs compared with non-NENs at the same anatomical site, highlight the need for improved access to specialist services and targeted service improvement.
Background 1L IO mono tx for advanced NSCLC is an option based on recent clinical trials. As there are few data regarding tx sequencing following 1L IO mono tx for NSCLC, there is interest in seeking evidence to identify optimal tx sequences in this setting. This analysis explored 2L systemic tx and overall survival (OS) in pts with NSCLC following 1L IO mono tx in a real-world setting. Methods A retrospective analysis of 2604 randomly selected pts with advanced (stage IIIB/IV) NSCLC treated in US practices (156 community and 3 academic sites) between Jan 2013 and Dec 2018 was conducted using the Flatiron Health EHR-derived database. Tx regimens were defined using only therapies initiated in the first 30 days of tx. 1L tx was defined as tx received prior to disease progression (PD); 2L tx was defined as first tx after first PD. 2L tx patterns and OS were assessed in pts treated with 1L IO mono tx. OS and 95% CIs were calculated using Kaplan-Meier (KM) methods. Results Pts treated with 1L IO mono tx (initiated after 01 Jan 2016) at each site were identified in the database (N = 105). 91 pts were eligible for the initial exploratory analysis (platinum-based doublet/triplet, n = 35; single-agent chemo, n = 26; IO ± chemo, n = 15; other, n = 15; Table). A multivariable-adjusted KM analysis of 2L OS revealed longer survival with platinum-based doublet/triplet (24.4 months) vs IO ± chemo (17.9 months), other (11.6 months), and single-agent chemo (4.7 months). Conclusions Although the longest survival was in the platinum-based cohort, the unknown tx strategy for 1L IO mono tx and a small sample size limit the generalizability of the data. The hypothesis-generating result suggests further research on the efficacy of 2L platinum therapy after 1L IO tx is needed. Additional analyses of complementary real-world data in an NSCLC population treated with IO in the 1L are planned.

OBJECTIVE:Neuroendocrine tumors (NETs) are being seen increasingly frequently, and recent data show that long-acting somatostatin analogues have become a major initial treatment, regardless of whether the tumors are functioning or not. However, test dosing with subcutaneous (sc) octreotide is usually advised to assess longer-term tolerability, although this advice is mainly based on results with functioning tumors. The aim of the study was to assess the value of an initiating test dose of sc octreotide on the prediction of subsequent adverse events after treatment with the long-acting analogue.METHODS:In a single, large Centre of Excellence for NETs, a first cohort of patients (n = 24) was admitted overnight after an sc injection of octreotide, and then administered the analogue; a subsequent group (n = 53) had the test dose performed on an outpatient basis. Side effects were recorded after the test dose and subsequent treatment with the long-acting analogue.RESULTS:The test dose injection was of little value in predicting adverse events following the long-acting somatostatin analogue.CONCLUSION:Unless there are serious symptoms associated with a functioning NET, it is unnecessary to carry out a test dose; a change to this procedure will improve resource allocation and should enhance early initiation onto maintenance therapy.ABBREVIATIONS:CLARINET = Controlled study of lanreotide antiproliferative response in neuroendocrine tumors LAR = long-acting repeatable NET = neuroendocrine tumor PROMID = Placebo-controlled, double-blind, prospective, randomized study on the effect of octreotide LAR in the control of tumor growth in patients with meta-static neuroendocrine midgut tumors.

There have been no new licenced therapies for mesothelioma in over a decade. Ganetespib is a small-molecule heat-shock protein 90 (Hsp90) inhibitor, with significant activity for down-regulating Hsp90 client protein levels. Prior evidence indicates efficacy for ganetespib in mesothelioma through critical survival pathways and synergies with antifolates and platinum chemotherapy. We conducted a dose-escalation study of ganetespib in patients with pleural malignant mesothelioma and ECOG 0-1. Ganetespib was combined with standard pemetrexed/platinum therapy, using either cisplatin (GCisP), or carboplatin (GCarbP). Three ganetespib cohorts were: 100, 150 and 200mg/m2 given days 1 and 15, every 21 days. GCisP was evaluated using a 3+3 design. GCarbP followed an accelerated titration run-in using single patients, switching to a 3+3 design after one dose limiting toxicity (DLT). DLT was assessed during cycles 1-2 for GCisP and cycle 1 for GCarbP. Genomic instability was inferred by array-based analysis of somatic copy number. 27 patients were treated (GCisP, n=16; GCarbP, n=11). Median age 66 (range 37-76), 6 PS-0/21 PS-1, and 25 male. Only 3 patients experienced DLTs, all at 200mg/m2: grade 3 nausea (GCisP, n=1; GCarbP, n=1); grade 2 infusion-related reaction (GCarbP, n=1). This dose was the maximum tolerated dose. Partial tumour response rate was 61% (14/23 evaluable patients); 7 patients had tumour burden reduction of >50% (Figure). PFS was better using 200mg/m2 versus 100mg/m2 (hazard ratio 0.32, 95%CI 0.11-0.95, p=0.04). One patient remains progression-free even after 37 months. Total loss of heterozygosity (LOH) was correlated with increased tumour burden (n=7, correlation=0.7, p=0.078). Figure. Best tumour response (% change in tumour burden from baseline). Ganetespib plus pemetrexed and platinum chemotherapy was well-tolerated in patients with pleural mesothelioma, with evidence of activity, particularly at the recommended dose of 200mg/m2. LOH correlated with poorer response to this triplet combination.
Purpose Primary ovarian neuroendocrine tumors (NETs) develop in pure form or in association with other tumors, mainly teratomas. The available data regarding this rare condition are limited. Much of the literature focuses on single case reports, previously dismissed as a totally benign disorder, and thus long-term considerations and evidence-based management guidelines are lacking. The objective of the current study was to describe the clinical and pathologic characteristics and the effect of various therapeutic modalities on patient morbidity and mortality from 2 major centers. A secondary objective was to highlight that carcinoid syndrome may be manifest in the absence of metastatic disease. Methods The authors retrospectively studied a cohort of 34 consecutive patients with primary ovarian NETs who attended either the Oxford University Hospitals or Beatson Oncology Centre, Glasgow, between 1984 and 2014, and had their ovarian carcinoid data (eg, tumor growth, chemotherapy regimen) and mortality outcomes assessed. Results All patients were women, with an average age of 53 years (range, 23-87 years) at diagnosis. Of the 34 patients, 8 patients (23.5%) presented with carcinoid symptoms. Carcinoid heart disease was evident in 2 of the 34 patients (6%). All patients had a primary ovarian carcinoid tumor on histopathology, and 2 patients had bilateral ovarian carcinoids. Teratoma associations could be assessed in 29 tumors, with 20 (69%) of 29 showing a pathological association. The mean tumor size was 48 mm (range, 4-120 mm; SD, 40 mm). The mean follow-up was 4.5 years, ranging up to 17 years. The disease has been quiescent with no evidence of relapse in 22 of 34 patients; in 12 of 34 patients, it was metastatic. There were 5 patients who received treatment with somatostatin analogs or chemotherapy, whereas 8 patients (23.5%) died of disease. Metastatic disease was found up to 11 years from initial diagnosis. Conclusions Primary ovarian NET is rare and likely underrepresented in the literature. It can no longer be simply dismissed as a generally benign entity and may present with both the carcinoid syndrome and carcinoid heart disease. It requires careful evaluation and long-term review.

BACKGROUND:This randomized phase 2 trial compared the efficacy and safety of second-line nanoparticle albumin-bound paclitaxel (nab-paclitaxel) with or without the addition of CC-486 (an oral formulation of 5-azacytidine) in patients with advanced-stage, nonsquamous non-small cell lung cancer. METHODS:Patients were randomized to receive either nab-paclitaxel 100 mg/m2 on days 8 and 15 plus CC-486 200 mg daily on days 1 to 14 or single-agent nab-paclitaxel 100 mg/m2 on days 1 and 8, with both regimens administered every 21 days until tumor progression or unacceptable toxicity. The primary endpoint was progression-free survival. Secondary endpoints included the overall response rate, the disease control rate, and overall survival. RESULTS:Between January 2015 and August 2016, 161 patients were randomized (81 to the combination arm and 80 to the single-agent nab-paclitaxel arm). There was no benefit from the addition of CC-486 to nab-paclitaxel. The median progression-free survival was 3.2 months for the combination and 4.2 months for single-agent nab-paclitaxel (hazard ratio, 1.3; 95% confidence interval, 0.9-1.9). The median overall survival was 8.1 months in the combination arm and 17 months in the single-agent nab-paclitaxel arms (hazard ratio, 1.7; 95% confidence interval, 1.08-2.57). Grade 3 or greater treatment-related, emergent adverse events were reported by 40.5% of patients in the combination arm and by 31.6% of those in the single-agent nab-paclitaxel arm. CONCLUSIONS:Single-agent nab-paclitaxel was associated with promising outcomes and a tolerable safety profile as second-line treatment for patients with advanced-stage, nonsquamous non-small cell lung cancer. There was no benefit from the addition of CC-486 to nab-paclitaxel.
