There are currently no standard first-line treatment options for patients with higher grade 2–3, well-differentiated, advanced, gastroenteropancreatic neuroendocrine tumours. We aimed to investigate the efficacy and safety of first-line [177Lu]Lu-DOTA-TATE (177Lu-Dotatate) treatment. NETTER-2 was an open-label, randomised, parallel-group, superiority, phase 3 trial. We enrolled patients (aged ≥15 years) with newly diagnosed higher grade 2 (Ki67 ≥10% and ≤20%) and grade 3 (Ki67 >20% and ≤55%), somatostatin receptor-positive (in all target lesions), advanced gastroenteropancreatic neuroendocrine tumours from 45 centres across nine countries in North America, Europe, and Asia. We used interactive response technologies to randomly assign (2:1) patients to receive four cycles (cycle interval was 8 weeks ± 1 week) of intravenous 177Lu-Dotatate plus intramuscular octreotide 30 mg long-acting repeatable (LAR) then octreotide 30 mg LAR every 4 weeks (177Lu-Dotatate group) or high-dose octreotide 60 mg LAR every 4 weeks (control group), stratified by neuroendocrine tumour grade (2 vs 3) and origin (pancreas vs other). Tumour assessments were done at baseline, week 16, and week 24, and then every 12 weeks until disease progression or death. The primary endpoint was progression-free survival by blinded, independent, central radiology assessment. We did the primary analysis at 101 progression-free survival events as the final progression-free survival analysis. NETTER-2 is registered with ClinicalTrials.gov, NCT03972488, and is active and not recruiting. Between Jan 22, 2020, and Oct 13, 2022, we screened 261 patients, 35 (13%) of whom were excluded. We randomly assigned 226 (87%) patients (121 [54%] male and 105 [46%] female) to the 177Lu-Dotatate group (n=151 [67%]) and control group (n=75 [33%]). Median progression-free survival was 8·5 months (95% CI 7·7–13·8) in the control group and 22·8 months (19·4–not estimated) in the 177Lu-Dotatate group (stratified hazard ratio 0·276 [0·182–0·418]; p<0·0001). During the treatment period, adverse events (of any grade) occurred in 136 (93%) of 147 treated patients in the 177Lu-Dotatate group and 69 (95%) of 73 treated patients in the control group. There were no study drug-related deaths during the treatment period. First-line 177Lu-Dotatate plus octreotide LAR significantly extended median progression-free survival (by 14 months) in patients with grade 2 or 3 advanced gastroenteropancreatic neuroendocrine tumours. 177Lu-Dotatate should be considered a new standard of care in first-line therapy in this population.

Approximately 7% of pancreatic cancers occur in patients with a germline mutation in BRCA1 or BRCA2 , an alteration that compromises DNA repair. In a randomized trial in patients with metastatic pancreatic cancer that had responded to platinum-based chemotherapy, progression-free survival was nearly twice as long with olaparib than with placebo (7.4 months vs. 3.8 months).

Background: Modifications of FOLFIRINOX are widely used despite the absence of prospective data validating efficacy in metastatic disease (metastatic pancreatic cancer (MPC)) or locally advanced pancreatic cancer (LAPC). We conducted a multicentre phase II study of modified FOLFIRINOX in advanced pancreatic cancer to assess the impact of dose attenuation in MPC and efficacy in LAPC. Methods: Patients with untreated MPC or LAPC received modified FOLFIRINOX (irinotecan and bolus 5-fluorouracil reduced by 25%). Adverse events (AEs) were compared with full-dose FOLFIRINOX. Response rate (RR), median progression-free survival (PFS) and median overall survival (OS) were determined. Results: In total, 31 and 44 patients with LAPC and MPC were enrolled, respectively. In MPC, efficacy of modified FOLFIRINOX was comparable with FOLFIRINOX with RR 35.1%, OS 10.2 months (95% CI 7.65–14.32) and PFS 6.1 months (95% CI 5.19–8.31). In LAPC, efficacy was notable with RR 17.2%, resection rate 41.9%, PFS 17.8 months (95% CI 11.0–23.9) and OS 26.6 months (95% CI 16.7, NA). Neutropenia ( P <0.0001), vomiting ( P <0.001) and fatigue ( P =0.01) were significantly decreased. [ 18 F]-Fluorodeoxyglucose positron emission tomography imaging response did not correlate with PFS or OS. Conclusions: In this first prospective study of modified FOLFIRINOX in MPC and LAPC, we observed decreased AEs compared with historical control patients. In MPC, the efficacy appears comparable with FOLFIRINOX. In LAPC, PFS and OS were prolonged and support the continued use of FOLFIRINOX in this setting.

In a phase 1–2 trial involving patients with advanced pancreatic cancer, sotorasib (a KRAS G12C inhibitor) resulted in a response in 21% of the patients and a median progression-free survival of 4 months.

Pancreatic ductal adenocarcinoma remains one of the most lethal malignancies, with few treatment options. NAPOLI 3 aimed to compare the efficacy and safety of NALIRIFOX versus nab-paclitaxel and gemcitabine as first-line therapy for metastatic pancreatic ductal adenocarcinoma (mPDAC). NAPOLI 3 was a randomised, open-label, phase 3 study conducted at 187 community and academic sites in 18 countries worldwide across Europe, North America, South America, Asia, and Australia. Patients with mPDAC and Eastern Cooperative Oncology Group performance status score 0 or 1 were randomly assigned (1:1) to receive NALIRIFOX (liposomal irinotecan 50 mg/m2, oxaliplatin 60 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2, administered sequentially as a continuous intravenous infusion over 46 h) on days 1 and 15 of a 28-day cycle or nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2, administered intravenously, on days 1, 8, and 15 of a 28-day cycle. Balanced block randomisation was stratified by geographical region, performance status, and liver metastases, managed through an interactive web response system. The primary endpoint was overall survival in the intention-to-treat population, evaluated when at least 543 events were observed across the two treatment groups. Safety was evaluated in all patients who received at least one dose of study treatment. This completed trial is registered with ClinicalTrials.gov, NCT04083235. Between Feb 19, 2020 and Aug 17, 2021, 770 patients were randomly assigned (NALIRIFOX, 383; nab-paclitaxel–gemcitabine, 387; median follow-up 16·1 months [IQR 13·4–19·1]). Median overall survival was 11·1 months (95% CI 10·0–12·1) with NALIRIFOX versus 9·2 months (8·3–10·6) with nab-paclitaxel–gemcitabine (hazard ratio 0·83; 95% CI 0·70–0·99; p=0·036). Grade 3 or higher treatment-emergent adverse events occurred in 322 (87%) of 370 patients receiving NALIRIFOX and 326 (86%) of 379 patients receiving nab-paclitaxel–gemcitabine; treatment-related deaths occurred in six (2%) patients in the NALIRIFOX group and eight (2%) patients in the nab-paclitaxel–gemcitabine group. Our findings support use of the NALIRIFOX regimen as a possible reference regimen for first-line treatment of mPDAC. Ipsen. For the plain language summary see Supplementary Materials section.

Treatment options for patients with advanced neuroendocrine tumors are limited. The efficacy of cabozantinib in the treatment of previously treated, progressive extrapancreatic or pancreatic neuroendocrine tumors is unclear. We enrolled two independent cohorts of patients - those with extrapancreatic neuroendocrine tumors and those with pancreatic neuroendocrine tumors - who had received peptide receptor radionuclide therapy or targeted therapy or both. Patients were randomly assigned in a 2:1 ratio to receive cabozantinib at a dose of 60 mg daily or placebo. The primary end point was progression-free survival as assessed by blinded independent central review. Key secondary end points included objective response, overall survival, and safety. In the cohort of 203 patients with extrapancreatic neuroendocrine tumors, the median progression-free survival with cabozantinib was 8.4 months, as compared with 3.9 months with placebo (stratified hazard ratio for progression or death, 0.38; 95% confidence interval [CI], 0.25 to 0.59; P<0.001). In the cohort of 95 patients with pancreatic neuroendocrine tumors, the median progression-free survival with cabozantinib was 13.8 months, as compared with 4.4 months with placebo (stratified hazard ratio, 0.23; 95% CI, 0.12 to 0.42; P<0.001). The incidence of confirmed objective response with cabozantinib was 5% and 19% among patients with extrapancreatic and pancreatic neuroendocrine tumors, respectively, as compared with 0% with placebo. Grade 3 or higher adverse events were noted in 62 to 65% of the patients treated with cabozantinib, as compared with 23 to 27% of the patients who received placebo. Common treatment-related adverse events of grade 3 or higher included hypertension, fatigue, diarrhea, and thromboembolic events. Cabozantinib, as compared with placebo, significantly improved progression-free survival in patients with previously treated, progressive advanced extrapancreatic or pancreatic neuroendocrine tumors. Adverse events were consistent with the known safety profile of cabozantinib. (Funded by the National Cancer Institute and others; CABINET ClinicalTrials.gov number, NCT03375320.).

The ESPAC-3 trial showed that adjuvant gemcitabine is the standard of care based on similar survival to and less toxicity than adjuvant 5-fluorouracil/folinic acid in patients with resected pancreatic cancer. Other clinical trials have shown better survival and tumour response with gemcitabine and capecitabine than with gemcitabine alone in advanced or metastatic pancreatic cancer. We aimed to determine the efficacy and safety of gemcitabine and capecitabine compared with gemcitabine monotherapy for resected pancreatic cancer. We did a phase 3, two-group, open-label, multicentre, randomised clinical trial at 92 hospitals in England, Scotland, Wales, Germany, France, and Sweden. Eligible patients were aged 18 years or older and had undergone complete macroscopic resection for ductal adenocarcinoma of the pancreas (R0 or R1 resection). We randomly assigned patients (1:1) within 12 weeks of surgery to receive six cycles of either 1000 mg/m2 gemcitabine alone administered once a week for three of every 4 weeks (one cycle) or with 1660 mg/m2 oral capecitabine administered for 21 days followed by 7 days' rest (one cycle). Randomisation was based on a minimisation routine, and country was used as a stratification factor. The primary endpoint was overall survival, measured as the time from randomisation until death from any cause, and assessed in the intention-to-treat population. Toxicity was analysed in all patients who received trial treatment. This trial was registered with the EudraCT, number 2007-004299-38, and ISRCTN, number ISRCTN96397434. Of 732 patients enrolled, 730 were included in the final analysis. Of these, 366 were randomly assigned to receive gemcitabine and 364 to gemcitabine plus capecitabine. The Independent Data and Safety Monitoring Committee requested reporting of the results after there were 458 (95%) of a target of 480 deaths. The median overall survival for patients in the gemcitabine plus capecitabine group was 28·0 months (95% CI 23·5–31·5) compared with 25·5 months (22·7–27·9) in the gemcitabine group (hazard ratio 0·82 [95% CI 0·68–0·98], p=0·032). 608 grade 3–4 adverse events were reported by 226 of 359 patients in the gemcitabine plus capecitabine group compared with 481 grade 3–4 adverse events in 196 of 366 patients in the gemcitabine group. The adjuvant combination of gemcitabine and capecitabine should be the new standard of care following resection for pancreatic ductal adenocarcinoma. Cancer Research UK.

Surufatinib showed superior efficacy in extrapancreatic neuroendocrine tumours (NETs) in the phase 3 SANET-ep study. In SANET-p, we aimed to assess the efficacy and safety of surufatinib in patients with advanced pancreatic NETs. SANET-p was a multicentre, randomised, double-blind, placebo-controlled, phase 3 study, done in 21 hospitals across China. Eligible patients were adults (aged 18 years or older) with progressive, advanced, well differentiated pancreatic NETs, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and progression on up to two kinds of previous systemic regimens for advanced disease. Patients were randomly assigned (2:1) via an interactive web response system to receive 300 mg of surufatinib or placebo, taken orally once per day in consecutive 4-week treatment cycles until disease progression, intolerable toxicity, withdrawal of consent, poor compliance, use of other antitumour medication, pregnancy, loss to follow-up, or if the investigator deemed discontinuation in the patient's best interest. Randomisation was done centrally using stratified block randomisation (block size three), stratified by pathological grade, previous systemic antitumour treatment, and ECOG performance status score. Patients, investigators, research staff, and the sponsor study team were masked to treatment allocation. Crossover to surufatinib was permitted for patients in the placebo group with disease progression. The primary endpoint was investigator-assessed progression-free survival in the intention-to-treat population, which included all patients in randomisation. A pre-planned interim analysis was done at 70% of the predicted progression-free survival events. This study is registered at ClinicalTrials.gov, NCT02589821. Between Feb 18, 2016, and Nov 11, 2019, of 264 patients who were screened, 172 (65%) patients were randomly assigned to receive surufatinib (n=113) or placebo (n=59). The median follow-up was 19·3 months (95% CI 9·3–19·4) in the surufatinib group and 11·1 months (5·7–35·9) in the placebo group. The median investigator-assessed progression-free survival was 10·9 months (7·5–13·8) for surufatinib versus 3·7 months (2·8–5·6) for placebo (hazard ratio 0·49, 95% CI 0·32–0·76; p=0·0011). The trial met the early stopping criteria at the interim analysis and was terminated on recommendation from the independent data monitoring committee. The most common grade 3 or worse treatment-related adverse events were hypertension (43 [38%] of 113 with surufatinib vs four [7%] of 59 with placebo), proteinuria (11 [10%] vs one [2%]), and hypertriglyceridaemia (eight [7%] vs none). Treatment-related serious adverse events were reported in 25 (22%) patients in the surufatinib group and four (7%) patients in the placebo group. There were three on-treatment deaths in the surufatinib group, including two deaths due to adverse events (gastrointestinal haemorrhage [possibly treatment-related] and cerebral haemorrhage [unlikely to be treatment-related]), and one death attributed to disease progression. One on-treatment death in the placebo group was attributed to disease progression. Surufatinib significantly improves progression-free survival and has an acceptable safety profile in patients with progressive, advanced pancreatic NETs, and could be a potential treatment option in this patient population.

Background Based on current guidelines, surgical treatment of hepatic oligometastases in patients with pancreatic ductal adenocarcinoma (PDAC) is not primarily recommended. Systematic chemotherapy is the therapy of choice for these patients. The relevance of subsequent surgical resection after chemotherapy remains unclear. This multicentre, randomized, controlled phase III trial is planned to evaluate whether resection of the primary tumor and liver metastases can improve overall survival in patients with PDAC with hepatic oligometastases in a multimodal treatment setting. Methods After an induction therapy with eight cyles of mFOLFIRINOX and a response assessment after four and eight cycles, patients will be randomized to either Arm 1 (perioperative mFOFIRINOX plus resection of the primary tumor with resection or ablation of all hepatic metastases) or Arm 2 (continuation of 4 cycles of the standard-of-care mFOLFIRINOX chemotherapy). This clinical trial will focus on a well-defined patient group with metastatic disease limited to the liver as the target organ, with a maximum of three metastases. Discussion METAPANC is the first international, randomized, controlled, open-label, multicentre, phase III clinical trial for curative intended surgical therapy of oligometastatic pancreatic cancer in Europe and America. The multimodal surgical treatment of patients with oligometastatic pancreatic cancer could significantly extend the overall survival of this patient group. A possible recommendation of this multimodal treatment regimen outside of clinical trials requires data from randomized controlled trials first. To identify patient subgroups that might benefit from multimodal surgical therapy, additional information on tumor genetics could supplement valid parameters.

Therapeutic options for advanced neuroendocrine tumours (NETs) are limited. We investigated the efficacy and safety of surufatinib (HMPL-012, sulfatinib) in patients with extrapancreatic NETs. SANET-ep was a randomised, double-blind, placebo-controlled, phase 3 trial undertaken at 24 hospitals across China. Patients (aged 18 years or older) with unresectable or metastatic, well differentiated, extrapancreatic NETs, with an Eastern Cooperative Oncology Group performance status of 0 or 1, and progression on no more than two types of previous systemic regimens were enrolled. Patients were centrally randomly assigned (2:1) using stratified block randomisation (block size 3) via an interactive web response system to receive oral surufatinib at 300 mg per day or matching placebo. Randomisation was stratified by tumour origin, pathological grade, and previous treatment. Patients, investigators, research staff and the sponsor study team were masked to treatment allocation. Crossover to the surufatinib group was allowed for patients in the placebo group at disease progression. The primary endpoint was investigator-assessed progression-free survival, which was analysed in the intention-to-treat population. A preplanned interim analysis was done at 70% of predicted progression-free survival events. This study was registered with ClinicalTrials.gov, NCT02588170. Follow-up is ongoing. Between Dec 9, 2015, and March 31, 2019, 198 patients were randomly assigned to surufatinib (n=129) or placebo (n=69). Median follow-up was 13·8 months (95% CI 11·1–16·7) in the surufatinib group and 16·6 months (9·2–not calculable) in the placebo group. Investigator-assessed median progression-free survival was 9·2 months (95% CI 7·4–11·1) in the surufatinib group versus 3·8 months (3·7–5·7) in the placebo group (hazard ratio 0·33; 95% CI 0·22–0·50; p<0·0001). As the trial met the predefined criteria for early discontinuation of the study at the interim analysis, the study was terminated early, as recommended by the independent data monitoring committee. The most common treatment-related adverse events of grade 3 or worse were hypertension (47 [36%] of 129 patients in the surufatinib group vs nine [13%] of 68 patients in the placebo group) and proteinuria (25 [19%] vs zero). Treatment-related serious adverse events were reported in 32 (25%) of 129 patients in the surufatinib group and nine (13%) of 68 patients in the placebo group. Treatment-related deaths occurred in three patients in the surufatinib group (disseminated intravascular coagulation and hepatic encephalopathy, liver injury, and death with unknown reason) and one patient in the placebo group (cachexia and respiratory failure). Progression-free survival was significantly longer in patients given surufatinib compared with patients given placebo, and surufatinib has a favourable benefit-to-risk profile in patients with progressive, advanced, well differentiated extrapancreatic NETs. Our results suggest that surufatinib might be a new treatment option for this population. Hutchison MediPharma.
