- BackgroundThere are no data from prospective studies focused exclusively on patients with advanced lung and thymic carcinoids. We aimed to assess the efficacy and safety of long-acting pasireotide and everolimus, administered alone or in combination, in patients with advanced carcinoids of the lung or thymus.MethodsLUNA was a prospective, multicentre, randomised, open-label, phase 2 trial of adult patients (aged >18 years) with advanced (unresectable or metastatic), well differentiated carcinoid tumours of the lung or thymus, with radiological progression within 12 months before randomisation, and a WHO performance status of 0–2. At each centre, the investigator or their designee registered each patient using an interactive voice recognition system into one of the three treatment groups. The randomisation allocation sequence was generated by an external company; patients were randomly assigned (1:1:1) to receive treatment with long-acting pasireotide (60 mg intramuscularly every 28 days), everolimus (10 mg orally once daily), or both in combination, for the core 12-month treatment period. Patients were stratified by carcinoid type (typical vs atypical) and line of study treatment (first line vs others). The primary endpoint was the proportion of patients progression-free at month 9, defined as the proportion of patients with overall lesion assessment at month 9 showing a complete response, partial response, or stable disease according to local Response Evaluation Criteria in Solid Tumors, version 1.1, assessed in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study drug and had at least one post-baseline safety assessment. The trial is registered with ClinicalTrials.gov, number NCT01563354. The extension phase of the study is ongoing.FindingsBetween Aug 16, 2013, and Sept 30, 2014, 124 patients were enrolled from 36 centres in nine countries: 41 were allocated to the long-acting pasireotide group, 42 to the everolimus group, and 41 to the combination group. At month 9, the proportion of patients with an overall lesion assessment of complete response, partial response, or stable disease was 16 of 41 patients (39·0%, 95% CI 24·2–55·5) in the long-acting pasireotide group, 14 of 42 patients (33·3%, 19·6–49·5) in the everolimus group, and 24 of 41 patients (58·5%, 42·1–73·7) in the combination group. The most common grade 1–2 adverse events with a suspected association with long-acting pasireotide monotherapy were diarrhoea (15 [37%] of 41), hyperglycaemia (17 [41%]), and weight loss (8 [20%]); those with a suspected association with everolimus monotherapy were stomatitis (26 [62%] of 42) and diarrhoea (16 [38%]); and those suspected to be associated with combination treatment were hyperglycaemia (27 [66%] of 41]), diarrhoea (19 [46%]), and asthenia (8 [20%]). The most common grade 3–4 adverse events with a suspected association with long-acting pasireotide monotherapy were γ-glutamyltransferase increased (four [10%] of 41 patients), diarrhoea (three [7%]), and hyperglycaemia (three [7%]); those for everolimus were hyperglycaemia (seven [17%] of 42 patients), stomatitis (four [10%]), and diarrhoea (three [7%]); those for combination treatment were hyperglycaemia (nine [22%] of 41 patients) and diarrhoea (four [10%]). 11 patients died during the core 12-month treatment phase or up to 56 days after the last study treatment exposure date: two (5%) of 41 in the long-acting pasireotide group, six (14%) of 42 in the everolimus group, and three (7%) of 41 in the combination group. No deaths were suspected to be related to long-acting pasireotide treatment. One death in the everolimus group (acute kidney injury associated with diarrhoea), and two deaths in the combination group (diarrhoea and urinary sepsis in one patient, and acute renal failure and respiratory failure in one patient) were suspected to be related to everolimus treatment. In the latter patient, acute renal failure was not suspected to be related to everolimus treatment, but respiratory failure was suspected to be related.InterpretationThe study met the primary endpoint in all three treatment groups. Safety profiles were consistent with the known safety profiles of these agents. Further studies are needed to confirm the antitumour efficacy of the combination of a somatostatin analogue with everolimus in lung and thymic carcinoids.

- Systemic chemotherapy is indicated in progressive or bulky advanced pancreatic neuroendocrine tumors (NETs) and in grade 3 (G3) neuroendocrine neoplasms (NENs) as per ENETS guidelines. Chemotherapy may be considered in NETs of other sites (lung, thymus, stomach, colon, and rectum) under certain conditions (e.g., when Ki-67 is at a high level [upper G2 range], in rapidly progressive disease and/or after failure of other therapies, or if somatostatin receptor imaging is negative). An ENETS Consensus Conference was held in Antibes (2015) to elaborate guidelines on the standards of care of different diagnostic procedures and therapeutic interventions in NENs. This article provides guidance on chemotherapy including therapeutic indications, dosing schedules, adverse events (including prevention and management), drug interactions, and evaluation of treatment effect for the chemotherapy agents most commonly used in NENs (streptozocin, dacarbazine, fluoropyrimidines, platinum compounds, etoposide, and irinotecan).

- Purpose Preliminary studies suggested that telotristat ethyl, a tryptophan hydroxylase inhibitor, reduces bowel movement (BM) frequency in patients with carcinoid syndrome. This placebo-controlled phase III study evaluated telotristat ethyl in this setting. Patients and Methods Patients (N = 135) experiencing four or more BMs per day despite stable-dose somatostatin analog therapy received (1: 1: 1) placebo, telotristat ethyl 250 mg, or telotristat ethyl 500 mg three times per day orally during a 12-week double-blind treatment period. The primary end point was change from baseline in BM frequency. In an open-label extension, 115 patients subsequently received telotristat ethyl 500 mg. Results Estimated differences in BM frequency per day versus placebo averaged over 12 weeks were -0.81 for telotristat ethyl 250 mg (P < .001) and -0.69 for telotristat ethyl 500 mg (P,.001). At week 12, mean BM frequency reductions per day for placebo, telotristat ethyl 250 mg, and telotristat ethyl 500 mg were -0.9, -1.7, and -2.1, respectively. Responses, predefined as a BM frequency reduction >= 30% from baseline for >= 50% of the double-blind treatment period, were observed in 20%, 44%, and 42% of patients given placebo, telotristat ethyl 250 mg, and telotristat ethyl 500 mg, respectively. Both telotristat ethyl dosages significantly reduced mean urinary 5-hydroxyindole acetic acid versus placebo at week 12 (P < .001). Mild nausea and asymptomatic increases in gamma-glutamyl transferase were observed in some patients receiving telotristat ethyl. Follow-up of patients during the open-label extension revealed no new safety signals and suggested sustained BM responses to treatment. Conclusion Among patients with carcinoid syndrome not adequately controlled by somatostatin analogs, treatment with telotristat ethyl was generally safe and well tolerated and resulted in significant reductions in BM frequency and urinary 5-hydroxyindole acetic acid.

- Systemic therapies established in the management of patients with neuroendocrine tumors (NETs) include somatostatin analogs and interferon-alpha, also referred to as biotherapy. Recent randomized controlled studies have extended the knowledge on the frequency of side effects associated with biotherapy. More recently, novel targeted drugs, such as the mammalian target of rapamycin inhibitor everolimus and the multiple tyrosine kinase inhibitor sunitinib, have been introduced in the management of NETs. Although targeted drugs are generally well tolerated, with most adverse events being of mild to moderate severity and manageable, novel targeted drugs exhibit a distinct adverse event profile that warrants guidance for appropriate diagnostic and therapeutic management. This is particularly important given the widespread and potentially long-term use of everolimus in a broad spectrum of NETs and of sunitinib in pancreatic NETs. This review will focus on the most relevant toxicities associated with biotherapy and novel targeted drugs and on their management. For each drug class indication, administration and dosing schedule, most frequent adverse events, actions and dose adjustments for adverse events as well as their monitoring are presented. This review further covers the evaluation of treatment effect, patient information, drug interactions, and information on pregnancy.

- This 6-month, open, non-controlled, multicenter, dose-titration study evaluated the efficacy and safety of 28-day prolonged-release (PR) lanreotide in the treatment of carcinoid syndrome. Eligible patients had a carcinoid tumor with > or =3 stools/day and/or > or =1 moderate/severe flushing episodes/day. Six treatments of 28-day PR lanreotide were administered by deep subcutaneous injection. The dose for the first two injections was 90 mg. Subsequent doses could be titrated (60, 90, 120 mg) according to symptom response. Seventy-one patients were treated. Flushing decreased from a mean of 3.0 at baseline to 2.3 on day 1, and 2.0 on day 2, with a daily mean of 2.1 for the first week post-treatment (p < 0.05). Diarrhea decreased from a mean of 5.0 at baseline to 4.3 on day 1 (p < 0.05), and 4.5 on day 2, with a daily mean of 4.4 for the first week post-treatment (p < 0.001). Symptom frequency decreased further after the second and third injections, and reached a plateau after the fourth injection. By month 6, flushing and diarrhea had significantly decreased from baseline by a mean of 1.3 and 1.1 episodes/day, respectively (both p < or = 0.001); 65% of patients with flushing as the target symptom and 18% of diarrhea-target patients achieved > or =50% reduction from baseline. Median urinary 5-hydroxyindoleacetic acid and chromogranin A levels decreased by 24 and 38%, respectively. Treatment was well tolerated. 28-day PR lanreotide was effective in reducing the symptoms and biochemical markers associated with carcinoid syndrome.

- Contrast-enhanced computed tomography (CT) of the neckthorax-abdomen and pelvis, including 3-phase examination of the liver, constitutes the basic imaging for primary neuroendocrine tumor (NET) diagnosis, staging, surveillance, and therapy monitoring. CT characterization of lymph nodes is difficult because of inadequate size criteria (short axis diameter), and bone metastases are often missed. Contrast-enhanced magnetic resonance imaging (MRI) including diffusion-weighted imaging is preferred for the examination of the liver, pancreas, brain and bone. MRI may miss small lung metastases. MRI is less well suited than CT for the examination of extended body areas because of the longer examination procedure. Ultrasonography (US) frequently provides the initial diagnosis of liver metastases and contrast-enhanced US is excellent to characterize liver lesions that remain equivocal on CT/MRI. US is the method of choice to guide the biopsy needle for the histopathological NET diagnosis. US cannot visualize thoracic NET lesions for which CTguided biopsy therefore is used. Endocopic US is the most sensitive method to diagnose pancreatic NETs, and additionally allows for biopsy. Intraoperative US facilitates lesion detection in the pancreas and liver. Somatostatin receptor imaging should be a part of the tumor staging, preoperative imaging and restaging, for which 68 Ga-DOTA-somatostatin analog PET/CT is recommended, which is vastly superior to somatostatin receptor scintigraphy, and facilitates the diagnosis of most types of NET lesions, for example lymph node metastases, bone metastases, liver metastases, peritoneal lesions, and primary small intestinal NETs. (18)FDG-PET/CT is better suited for G3 and high G2 NETs, which generally have higher glucose metabolism and less somatostatin receptor expression than low-grade NETs, and additionally provides prognostic information.

- Purpose: In the placebo-controlled Phase III TELE-STAR (Telotristat Etiprate for Somatostatin Analogue Not Adequately Controlled Carcinoid Syndrome) trial, the oral tryptophan hydroxylase inhibitor telotristat ethyl significantly reduced bowel movement (BM) frequency during a 12-week, double-blind treatment period in 135 patients with metastatic neuroendocrine tumors with carcinoid syndrome and >= 4 BMs per day. Patients (mean [SD] age, 63.5 [8.9] years; mean [SD] body mass index, 24.9 [4.9] kg/m(2)) received placebo, telotristat ethyl 250 mg, or telotristat ethyl 500 mg 3 times per day (TID) in addition to somatostatin analogue therapy. Weight loss is associated with uncontrolled carcinoid syndrome and may be associated with reduced survival.Methods: Assessment of the occurrence of weight change >= 3% at week 12 was prespecified in the statistical analysis plan.Findings: In 120 patients with weight data available, weight gain >= 3% was observed in 2 of 39 patients (5.1%) taking placebo [1.1), 7 of 41 (17.1%) taking telotristat ethyl 250 mg TID, and 13 of 40 (32.5%) taking telotristat ethyl 500 mg TID (P = 0.0017) at week 12. Weight loss >= 3% was observed in 5 of 39 patients (12.8%) taking placebo TID, 4 of 41 (9.8%) taking telotristat ethyl 250 mg TID, and 6 of 40 (15.0%) taking telotristat ethyl 500 mg TID (P = 0.77). Biochemical and metabolic parameters of serum albumin and cholesterol significantly increased (P = 0.02 and P = 0.001, respectively) in patients gaining weight and decreased in patients who lost weight, suggesting an improvement in overall nutritional status.

- BACKGROUND: Everolimus, an oral inhibitor of mammalian target of rapamycin (mTOR), has shown antitumor activity in patients with advanced pancreatic neuroendocrine tumors, in two phase 2 studies. We evaluated the agent in a prospective, randomized, phase 3 study. METHODS: We randomly assigned 410 patients who had advanced, low-grade or intermediate-grade pancreatic neuroendocrine tumors with radiologic progression within the previous 12 months to receive everolimus, at a dose of 10 mg once daily (207 patients), or placebo (203 patients), both in conjunction with best supportive care. The primary end point was progression-free survival in an intention-to-treat analysis. In the case of patients in whom radiologic progression occurred during the study, the treatment assignments could be revealed, and patients who had been randomly assigned to placebo were offered open-label everolimus. RESULTS: The median progression-free survival was 11.0 months with everolimus as compared with 4.6 months with placebo (hazard ratio for disease progression or death from any cause with everolimus, 0.35; 95% confidence interval [CI], 0.27 to 0.45; P<0.001), representing a 65% reduction in the estimated risk of progression or death. Estimates of the proportion of patients who were alive and progression-free at 18 months were 34% (95% CI, 26 to 43) with everolimus as compared with 9% (95% CI, 4 to 16) with placebo. Drug-related adverse events were mostly grade 1 or 2 and included stomatitis (in 64% of patients in the everolimus group vs. 17% in the placebo group), rash (49% vs. 10%), diarrhea (34% vs. 10%), fatigue (31% vs. 14%), and infections (23% vs. 6%), which were primarily upper respiratory. Grade 3 or 4 events that were more frequent with everolimus than with placebo included anemia (6% vs. 0%) and hyperglycemia (5% vs. 2%). The median exposure to everolimus was longer than exposure to placebo by a factor of 2.3 (38 weeks vs. 16 weeks). CONCLUSIONS: Everolimus, as compared with placebo, significantly prolonged progression-free survival among patients with progressive advanced pancreatic neuroendocrine tumors and was associated with a low rate of severe adverse events.
