Therefore, the antiviral susceptibility profiles of human influenza viruses circulating in Germany were characterized.Methods: Between October 2019 (week 40/2019) and March 2022 (week 12/2022), nasal swabs from untreated patients with acute respiratory symptoms were collected in the national German influenza surveillance system. A total of 598 influenza viruses were isolated and analyzed for susceptibility to oseltamivir, zanamivir and peramivir, using a neuraminidase (NA) inhibition assay. In addition, next-generation sequencing was applied to assess molecular markers of resistance to NA, cap-dependent endonuclease (PA) and M2 ion channel inhibitors (NAI, PAI, M2I) in 367 primary clinical samples. Furthermore, a genotyping assay based on RT-PCR and pyrosequencing to rapidly assess the molecular resistance marker PA-I38X in PA genes was designed and established.Results: While NAI resistance in the strict sense, defined by a ≥ 10-fold (influenza A) or ≥ 5-fold (influenza B) increase of NAI IC50, was not detected, a subtype A(H1N1)pdm09 isolate displayed 2.3- to 7.5-fold IC50 increase for all three NAI. This isolate carried the NA-S247N substitution, which is known to enhance NAI resistance induced by NA-H275Y. All sequenced influenza A viruses carried the M2-S31N substitution, which confers resistance to M2I. Of note, one A(H3N2) virus displayed the PA-I38M substitution, which is associated with reduced susceptibility to the PAI baloxavir marboxil. Pyrosequencing analysis confirmed these findings in the original clinical specimen and in cultured virus isolate, suggesting sufficient replicative fitness of this virus mutant.Conclusion: Over the last three influenza seasons, the vast majority of influenza viruses in this national-level sentinel were susceptible to NAIs and PAIs. These findings support the use of antivirals in the upcoming influenza season.Keywords: influenza viruses, antiviral resistance, phenotypic assay, genotypic assay, surveillance, neuraminidase, cap-dependent endonuclease, baloxavir marboxil, molecular resistance marker

The present analysis focuses on the effect of everolimus on the East Asian-subgroup population of the RADIANT-4 study. Methods: Patients were randomized to receive everolimus 10 mg/day or matching placebo. The primary end point was PFS (central review). Secondary end points were overall response rate, safety, and tolerability. Results: Among 302 patients enrolled in RADIANT-4, 46 were included in the East Asian subgroup (everolimus, n=28; placebo, n=18) analysis. Everolimus was associated with an 82% reduction in the relative risk of disease progression or death (HR 0.18, 95% CI 0.09–0.38). The median PFS (central review) in this subgroup was 11.2 months with everolimus vs 3.1 months with placebo. Adverse events (AEs) occurred in all 28 patients treated with everolimus and ten patients receiving placebo. The majority of these AEs were grade 1 or 2. Most commonly reported (≥30% of incidence) drug-related AEs of any grade included stomatitis (75%, n=21) and rash (43%, n=12) in the everolimus arm. Conclusion: Everolimus demonstrated a clinically meaningful PFS benefit in the East Asian population. The safety findings were consistent with the known safety profile of everolimus. These results support the use of everolimus in the East Asian population with advanced, nonfunctional NETs of GI or lung origin.

Obesity and inflammation are both risk factors for a variety of cancers, including breast cancer in postmenopausal women. Intake of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) decreases the risk of breast cancer, and also reduces obesity-associated inflammation and insulin resistance, but whether the two effects are related is currently unknown. We tested this hypothesis in a postmenopausal breast cancer model using ovariectomized, immune-competent female mice orthotopically injected with Py230 mammary tumor cells. Obesity, whether triggered genetically or by high-fat diet (HFD) feeding, increased inflammation in the mammary fat pad and promoted mammary tumorigenesis. The presence of tumor cells in the mammary fat pad further enhanced the local inflammatory milieu. Tumor necrosis factor-alpha (TNF-α) was the most highly upregulated cytokine in the obese mammary fat pad, and we observed that TNF-α dose-dependently stimulated Py230 cell growth in vitro. An ω-3 PUFA-enriched HFD (referred to as fish oil diet, FOD) reduced inflammation in the obese mammary fat pad in the absence of tumor cells and inhibited Py230 tumor growth in vivo. Although some anti-inflammatory effects of ω-3 PUFAs were previously shown to be mediated by the G-protein-coupled receptor 120 (GPR120), the FOD reduced Py230 tumor burden in GPR120-deficient mice to a similar degree as observed in wild-type mice, indicating that the effect of FOD to reduce tumor growth does not require GPR120 in the host mouse. Instead, in vitro studies demonstrated that ω-3 PUFAs act directly on tumor cells to activate c-Jun N-terminal kinase, inhibit proliferation and induce apoptosis. Our results show that obesity promotes mammary tumor progression in this model of postmenopausal breast cancer and that ω-3 PUFAs, independent of GPR120, inhibit mammary tumor progression in obese mice.

Purpose: The role of (18)F FDG-PET in hepatocellular carcinoma (HCC) has not been firmly established. We conducted this study to investigate the clinical implication of SUVmax on (18)F FDG-PET as a prognostic factor in patients with HCC, especially in the metastatic setting. Methods: HCC patients with extrahepatic metastatic lesions were enrolled that were evaluated by (18)F FDG-PET before palliative systemic therapy, between January 2002 and December 2009 at the Seoul National University Hospital. We retrospectively analyzed the clinical outcome and the value of the SUVmax. Results: A total of 25 patients (men, 88.0%) were enrolled. The response rate and disease control rate was 18.2% (95% CI: 2.1-34.3) and 32.0% (95% CI: 16.3-56.5), respectively. The progression-free survival (PFS) and overall survival (OS) were 2.3 months (95% CI: 1.1-3.4) and 14.2 months (95% CI: 9.1-19.2), respectively. The univariate analysis of OS showed that SUVmax and alphafetoprotein (AFP) were significant prognostic factors (P = 0.023 and P = 0.006, respectively). The multivariate analysis of OS showed that SUVmax and AFP were significant prognostic factors (P = 0.008 and P = 0.006, respectively). SUVmax and AFP were independent prognostic factors for PFS, too (P = 0.010 and P = 0.016, respectively). When the patients were divided according to the SUVmax and AFP, the patients with an SUVmax < 4.9 and an AFP ≤ 400 ng/ml showed longer OS and PFS than the patients with SUVmax ≥ 4.9 or AFP > 400 ng/ml (26.7 months vs. 9.3 months, P < 0.001 and 5.6 months vs. 1.7 months, P = 0.012, respectively). Conclusions: The SUVmax of the (18)F FDG-PET has a prognostic value for OS and PFS in patients with metastatic HCC undergoing systemic therapy. The combined analysis of the SUVmax with AFP might provide more detailed prognostic information. [ABSTRACT FROM AUTHOR]

Background: There is no standard palliative chemotherapy regimen in biliary tract cancers (BTC). Fluoropyrimidine or gemcitabine, with or without platinum, are most frequently used. We conducted this study to clarify the efficacy of palliative chemotherapy in BTC.Methods: Patients with unresectable BTC treated with palliative chemotherapy between Oct 2001 and Aug 2006 at Seoul National University Hospital were reviewed retrospectively. Histologically confirmed cases of intrahepatic cholangiocarcinoma, gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater carcinoma were enrolled. We analyzed the efficacy of regimens: gemcitabine (G) versus fluoropyrimidine (F) and with or without platinum (P).Results: A total of 243 patients were enrolled. 159 patients (65%) were male and the median age of the patients was 60 years (range 26-81). Intrahepatic cholangiocarcinoma, gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater carcinoma were 92, 72, 58, and 21 cases, respectively. The median progression free survival (PFS) was 4.3 months (95% CI, 3.7-4.9) and median overall survival (OS) was 8.7 months (95% CI, 7.4-10.0). Ninety-nine patients received G-based chemotherapy (94 GP, 5 G alone), and 144 patients received F-based chemotherapy (83 FP, 61 F alone). The response rate (RR), disease control rate (DCR), PFS and OS of G-based chemotherapy versus F-based chemotherapy were 16.7% vs. 19.5% (P=0.591), 52.8% vs. 58.9% (P=0.372), 4.0 months vs. 4.3 months (P=0.816), and 7.8 months vs. 9.1 months (P=0.848), respectively. Sixty-six patients received F or G without P, and 177 patients received F or G with P. The RR, DCR, PFS and OS of chemotherapy without P versus chemotherapy including P were 12.7% vs. 20.6% (P=0.169), 46.0% vs. 60.6% (P=0.049), 3.3 months vs. 4.4 months (P=0.887), and 10.6 months vs. 8.1 months (P=0.257), respectively.Conclusion: In unresectable BTC, F-based and G-based chemotherapy showed similar efficacy in terms of RR, DCR, PFS and OS. The benefit of adding P to F or G was not significant except for DCR. Further prospective studies which define the efficacy of various chemotherapeutic regimens in BTC are warranted.

Triple-negative (TN) breast cancer, which is defined as being negative for the estrogen receptor (ER), the progesterone receptor (PR), and the human epidermal growth factor receptor 2 (HER-2), represents a subset of breast cancer with different biologic behaviour. We investigated the clinicopathologic characteristics and prognostic indicators of lymph node-negative TN breast cancer.~Background~Background~Medical records were reviewed from patients with node-negative breast cancer who underwent curative surgery at Seoul National University Hospital between Jan. 2000 and Jun. 2003. Clinicopathologic variables and clinical outcomes were evaluated.~Methods~Methods~Among 683 patients included, 136 had TN breast cancer and 529 had non-TN breast cancer. TN breast cancer correlated with younger age (< 35 y, p = 0.003), and higher histologic and nuclear grade (p < 0.001). It also correlated with a molecular profile associated with biological aggressiveness: negative for bcl-2 expression (p < 0.001), positive for the epidermal growth factor receptor (p = 0.003), and a high level of p53 (p < 0.001) and Ki67 expression (p < 0.00). The relapse rates during the follow-up period (median, 56.8 months) were 14.7% for TN breast cancer and 6.6% for non-TN breast cancer (p = 0.004). Relapse free survival (RFS) was significantly shorter among patients with TN breast cancer compared with those with non-TN breast cancer (4-year RFS rate 85.5% vs. 94.2%, respectively; p = 0.001). On multivariate analysis, young age, close resection margin, and triple-negativity were independent predictors of shorter RFS.~Results~Results~TN breast cancer had higher relapse rate and more aggressive clinicopathologic characteristics than non-TN in node-negative breast cancer. Thus, TN breast cancer should be integrated into the risk factor analysis for node-negative breast cancer.~Conclusion~Conclusions [ABSTRACT FROM AUTHOR]

Background: The objective of this study was to evaluate the efficacy and toxicity of infusional 5-fluorouracil (5-FU), folinic acid and oxaliplatin (modified FOLFOX-6) in patients with advanced gastric cancer (AGC), as first-line palliative combination chemotherapy. We also analyzed the predictive or prognostic value of germline polymorphisms of candidate genes associated with 5-FU and oxaliplatin.Methods: Seventy-three patients were administered a 2 hour infusion of oxaliplatin (100 mg/m2) and folinic acid (100 mg/m2) followed by a 46 hour continuous infusion of 5-FU (2,400 mg/m2). Genomic DNA from the patients' peripheral blood mononuclear cells was extracted. Ten polymorphisms within five genes were investigated including TS, GSTP, ERCC, XPD and XRCC.Results: The overall response rate (RR) was 43.8%. Median time to progression (TTP) and overall survival (OS) were 6.0 months and 12.6 months, respectively. Toxicities were generally tolerable and manageable. The RR was significantly higher in patients with a 6-bp deletion homozygote (-6 bp/-6 bp) in TS-3'UTR (55.0% vs. 30.3% in +6 bp/+6 bp or +6 bp/-6 bp, p = 0.034), and C/A or A/A in XPD156 (52.0% vs. 26.1% in C/C, p = 0.038). The -6 bp/-6 bp in TS-3'UTR was significantly associated with a prolonged TTP and OS. In a multivariate analysis, the 6-bp deletion in TS-3'UTR was identified as an independent prognostic marker of TTP (hazard ratio = 0.561, p = 0.032).Conclusion: Modified FOLFOX-6 chemotherapy appears to be active and well tolerated as first line chemotherapy in AGC patients. The 6-bp deletion in TS-3'UTR might be a candidate to select patients who are likely to benefit from 5-FU based modified FOLFOX-6 in future large scale trial. [ABSTRACT FROM AUTHOR]

Introduction: DESTINY-PanTumor02 (NCT04482309) evaluated the efficacy and safety of trastuzumab deruxtecan (T-DXd) in pretreated patients with human epidermal growth factor receptor 2 (HER2)-expressing [immunohistochemistry (IHC) 3+/2+] solid tumors across seven cohorts: endometrial, cervical, ovarian, bladder, biliary tract, pancreatic, and other. Subgroup analyses by HER2 status were previously reported by central HER2 IHC testing, determined at enrollment or confirmed retrospectively. Reflecting the testing methods available in clinical practice, most patients (n = 202; 75.7%) were enrolled based on local HER2 IHC testing. Here, we report outcomes by HER2 IHC status as determined by the local or central test results used for study enrollment., Methods: This phase 2, open-label study evaluated T-DXd (5.4 mg/kg once every 3 weeks) for HER2-expressing (IHC 3+/2+ by local or central testing) locally advanced or metastatic disease after ≥ 1 systemic treatment or without alternative treatments. The primary endpoint was investigator-assessed confirmed objective response rate (ORR). Secondary endpoints included safety, duration of response (DOR), progression-free survival (PFS), and overall survival., Results: In total, 111 (41.6%) and 151 (56.6%) patients were enrolled with IHC 3+ and IHC 2+ tumors, respectively. In patients with IHC 3+ tumors, investigator-assessed confirmed ORR was 51.4% [95% confidence interval (CI) 41.7, 61.0], and median DOR was 14.2 months (95% CI 10.3, 23.6). In patients with IHC 2+ tumors, investigator-assessed ORR was 26.5% (95% CI 19.6, 34.3), and median DOR was 9.8 months (95% CI 4.5, 12.6). Safety was consistent with the known profile of T-DXd., Conclusion: In line with previously reported results, T-DXd demonstrated clinically meaningful benefit in patients with HER2-expressing tumors, with the greatest benefit in patients with IHC 3+ tumors. These data support the antitumor activity of T-DXd in HER2-expressing solid tumors, irrespective of whether patients are identified by local or central HER2 IHC testing., (© 2024. The Author(s).)

Advances in cancer immunotherapy have transformed cancer care and realized unprecedented responses in many patients. The growing arsenal of novel therapeutics - including immune checkpoint inhibition (ICI), adoptive T cell therapies (ACTs), and cancer vaccines - reflects the success of cancer immunotherapy. The therapeutic benefits of these treatment modalities are generally attributed to the enhanced quantity and quality of antitumor CD8 + T cell responses. Nevertheless, CD4 + T cells are now recognized to play key roles in both the priming and effector phases of the antitumor immune response. In addition to providing T cell help through co-stimulation and cytokine production, CD4 + T cells can also possess cytotoxicity either directly on MHC class II-expressing tumor cells or to other cells within the tumor microenvironment (TME). The presence of specific populations of CD4 + T cells, and their intrinsic plasticity, within the TME can represent an important determinant of clinical response to immune checkpoint inhibitors, vaccines, and chimeric antigen receptor (CAR) T cell therapies. Understanding how the antitumor functions of specific CD4 + T cell types are induced while limiting their protumorigenic attributes will enable more successful immunotherapies., Competing Interests: Declaration of interests L.F. received research funding from Abbvie, Bavarian Nordic, Bristol-Myers Squibb, Dendreon, Janssen, Merck, Nektar, Roche/Genentech, and Parker Institute; served as a consultant to Abbvie, Actym, Amgen, Astra Zeneca, Atreca, Bioatla, Bolt, Bristol Myer Squibb, Crescendo, Daiichi Sankyo, Immunogenesis, Innovent, Merck, NGMBio, Nutcracker, RAPT, Senti, Sutro, and Roche/Genentech; and has ownership interests in Actym, Atreca, Bioatla, Bolt, Immunogenesis, Nutcracker, RAPT, and Senti, unrelated to this review., (Copyright © 2024 The Authors.

Oridonin, a natural terpenoid isolated from the leaves of Isodon rubescens (Hemsley) H.Hara, is widely used in oriental medicine for its anticancer properties across various cancer types. Despite its prevalent use, the toxic effects of oridonin on male reproduction, particularly its impact on sperm functions and the mechanisms involved, are not well understood. This study aimed to explore the effects and underlying mechanisms of oridonin on sperm functions. We initially treated Duroc boar spermatozoa with varying concentrations of oridonin (0, 5, 50, 75, 100, and 150 µM) and incubated them to induce capacitation. We then assessed cell viability and several sperm functions, including sperm motility and motion kinematics, capacitation status, and ATP levels. We also analyzed the expression levels of proteins associated with the phosphatidylinositol 3-kinase (PI3K)/phosphoinositide-dependent kinase-1 (PDK1)/protein kinase B (AKT) signaling pathway and phosphotyrosine proteins. Our results indicate that oridonin adversely affects most sperm functions in a dose-dependent manner. We observed significant decreases in AKT, p-AKT (Thr308), phosphatase and tensin homolog (PTEN), p-PDK1, and p-PI3K levels following oridonin treatment, alongside an abnormal increase in phosphotyrosine proteins. These findings suggest that oridonin may disrupt normal levels of tyrosine-phosphorylated proteins by inhibiting the PI3K/PDK1/AKT signaling pathway, which is crucial for cell proliferation, metabolism, and apoptosis, thus potentially harming sperm functions. Consequently, we recommend considering the reproductive toxicity of oridonin when using it as a therapeutic agent., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

The receptor tyrosine-kinase HER2 (also known as ErbB2) is a well-established therapeutic target in patients with breast or gastric cancer selected on the basis of HER2 overexpression on immunohistochemistry and/or ERBB2 amplification on in situ hybridization. With advances in cancer molecular profiling and increased implementation of precision medicine approaches into oncology practice, actionable HER2 alterations in solid tumours have expanded to include ERBB2 mutations in addition to traditional HER2 overexpression and ERBB2 amplification. These various HER2 alterations can be found in solid tumour types beyond breast and gastric cancer, although few HER2-targeted therapeutic options have been established for the other tumour types. Nevertheless, during the 5 years since our previous Review on this topic was published in this journal, obvious and fruitful progress in the development of HER2-targeted therapies has been made, including new disease indications, innovative drugs with diverse mechanisms of action and novel frameworks for approval by regulatory authorities. These advances have culminated in the recent histology-agnostic approval of the anti-HER2 antibody-drug conjugate trastuzumab deruxtecan for patients with HER2-overexpressing solid tumours. In this new Review, we provide an update on the current development landscape of HER2-targeted therapies beyond breast cancer, as well as anticipated future HER2-directed treatment strategies to overcome resistance and thereby improve efficacy and patient outcomes., (© 2024.

Background: Nivolumab + chemotherapy is now a standard of care for HER2-negative, previously untreated, unresectable or recurrent gastric/gastroesophageal junction cancer (advanced gastric cancer), but long-term follow-up data of clinical trials are limited., Methods: ATTRACTON-4 was a phase 3, double-blind, placebo-controlled trial in Japan, South Korea, and Taiwan. Patients were randomized to either nivolumab or placebo, both combined with the physician's choice of SOX (oral S-1 [tegafur-gimeracil-oteracil potassium] + oxaliplatin) or CAPOX (capecitabine + oxaliplatin). We report the primary endpoints-centrally assessed progression-free survival (PFS) and overall survival (OS)-and landmark analyses of OS among patients alive using 3-year follow-up data., Results: At the cutoff date (May 10, 2021), 17/359 patients in the nivolumab + chemotherapy group and 6/358 in the placebo + chemotherapy group were continuing study treatment. PFS (centrally assessed) was longer in the nivolumab + chemotherapy group (median 10.94 vs. 8.48 months; hazard ratio [HR] 0.67, 95% confidence interval [CI] 0.55-0.82). Although OS did not differ between the two groups (median 17.45 vs. 17.15 months; HR 0.89, 95% CI 0.75-1.05), the landmark analysis of OS, calculating HRs at each landmark time point (every month), was getting numerically better in the nivolumab + chemotherapy group over time. Approximately 80% of patients who achieved complete response in the nivolumab + chemotherapy group were alive at 3 years. No new safety signals or major late-onset select treatment-related adverse events were observed for nivolumab + chemotherapy., Conclusion: This 3-year follow-up of ATTRACTION-4 confirmed the long-term clinical benefit and manageable safety of nivolumab + chemotherapy in patients with previously untreated advanced gastric cancer., Trial Registration: NCT02746796., (© 2024.

Background: FGFR genomic aberrations occur in approximately 5-10% of human cancers. Erdafitinib has previously demonstrated efficacy and safety in FGFR-altered advanced solid tumors, such as gliomas, thoracic, gastrointestinal, gynecological, and other rare cancers. However, its efficacy and safety in Asian patients remain largely unknown. We conducted a multicenter, open-label, single-arm phase IIa study of erdafitinib to evaluate its efficacy in Asian patients with FGFR-altered advanced cholangiocarcinoma, non-small cell lung cancer (NSCLC), and esophageal cancer., Methods: Patients with pathologically/cytologically confirmed, advanced, or refractory tumors who met molecular and study eligibility criteria received oral erdafitinib 8 mg once daily with an option for pharmacodynamically guided up-titration to 9 mg on a 28-day cycle, except for four NSCLC patients who received erdafitinib 10 mg (7 days on/7 days off) as they were recruited before the protocol amendment. The primary endpoint was investigator-assessed objective response rate per RECIST v1.1. Secondary endpoints included progression-free survival, duration of response, disease control rate, overall survival, safety, and pharmacokinetics., Results: Thirty-five patients (cholangiocarcinoma: 22; NSCLC: 12; esophageal cancer: 1) were enrolled. At data cutoff (November 19, 2021), the objective response rate for patients with cholangiocarcinoma was 40.9% (95% CI, 20.7-63.6); the median progression-free survival was 5.6 months (95% CI, 3.6-12.7) and median overall survival was 40.2 months (95% CI, 12.4-not estimable). No patient with RET/FGFR-altered NSCLC achieved objective response and the disease control rate was 25.0% (95% CI, 5.5-57.2%), with three patients with stable disease. The single patient with esophageal cancer achieved partial response. All patients experienced treatment-emergent adverse events, and grade ≥ 3 treatment-emergent adverse events were reported in 22 (62.9%) patients. Hyperphosphatemia was the most frequently reported treatment-emergent adverse event (all-grade, 85.7%)., Conclusions: Erdafitinib demonstrated efficacy in a population of Asian patients in selected advanced solid tumors, particularly in those with advanced FGFR-altered cholangiocarcinoma. Treatment was tolerable with no new safety signals., Trial Registration: This trial is registered with ClinicalTrials.gov (NCT02699606); study registration (first posted): 04/03/2016., (© 2024.

What Is This Summary About?: Researchers wanted to study whether the research drug zanidatamab could help people with a type of cancer called biliary tract cancer. In some people, biliary tract cancer cells make extra copies of a gene called HER2 (also called ERBB2). This is known as being HER2-amplified. Zanidatamab is an antibody designed to destroy cancer cells that have higher-than-normal HER2 protein or gene levels. Zanidatamab is currently under research and is not yet approved for any diseases. Participants in this phase 2b clinical study had tumors that were HER2-amplified and at the advanced or metastatic stage. Participants also had cancer which had become worse after previous chemotherapy or had side effects that were too bad to continue chemotherapy. They also had to meet other requirements to be enrolled. Researchers measured the amount of HER2 protein in the tumor samples of the participants who were enrolled. There were 80 participants with tumors that were both HER2 amplified and had higher-than-normal HER2 protein amounts (considered to be 'HER2-positive'). There were 7 participants with tumors that were HER2-amplified, but had little-to-no levels of the HER2 protein (considered to be 'HER2-low'). All participants in the study were treated with zanidatamab and no other cancer treatments once every 2 weeks., What Are the Key Takeaways?: In the HER2-positive group, 33 of 80 (41%) participants had their tumors shrink by 30% or more of their original size. In half of these participants, their tumors did not grow for 13 months or longer. No participant in the HER2-low group had their tumors shrink by 30% or more. In total, 63 of 87 participants (72%) had at least one side effect believed to be related to zanidatamab treatment. Most side effects were mild or moderate in severity. No participant died from complications related to zanidatamab. Diarrhea was one of the more common side effects and was experienced by 32 of 87 participants (37%). Side effects related to receiving zanidatamab through the vein, such as chills, fever, or high blood pressure, were experienced by 29 of 87 participants (33%)., What Are the Conclusions Reported by the Researchers?: The results of this study support the potential for zanidatamab as a new therapy for people with HER2-positive biliary tract cancer after they had already received chemotherapy.

The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with biliary tract cancer (BTC), published in late 2022 were adapted in December 2023, according to established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with BTC. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with BTC representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and the Taiwan Oncology Society (TOS). The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different regions of Asia. Drug access and reimbursement in the different regions of Asia are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with BTC across the different countries and regions of Asia, drawing on the evidence provided by both Western and Asian trials, whilst respecting the differences in screening practices and molecular profiling, as well as age and stage at presentation. Attention is drawn to the disparity in the drug approvals and reimbursement strategies, between the different countries., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Background: In the preplanned interim analysis of the TOPAZ-1 study, durvalumab plus gemcitabine-cisplatin significantly improved overall survival versus placebo plus gemcitabine-cisplatin in participants with advanced biliary tract cancer. We aimed to report updated overall survival and safety data from TOPAZ-1 with additional follow-up and data maturity beyond the interim analysis., Methods: TOPAZ-1 was a phase 3, randomised, double-masked, placebo-controlled, global study done at 105 sites in 17 countries. Participants aged 18 years or older with unresectable, locally advanced, or metastatic biliary tract cancer were randomly assigned (1:1) to durvalumab plus gemcitabine-cisplatin or placebo plus gemcitabine-cisplatin using a computer-generated randomisation scheme, stratified by disease status and primary tumour location. Participants received durvalumab (1500 mg) or placebo on day 1 of each cycle every 3 weeks for up to eight cycles, plus gemcitabine (1000 mg/m 2 ) and cisplatin (25 mg/m 2 ) intravenously on days 1 and 8 of each cycle every 3 weeks for up to eight cycles, followed by durvalumab (1500 mg) or placebo monotherapy every 4 weeks until disease progression or other discontinuation criteria were met. Investigators and participants were masked to study treatment. The primary endpoint was overall survival. TOPAZ-1 met its primary endpoint at the preplanned interim analysis, and the study is active but no longer recruiting participants. Updated overall survival and safety data from TOPAZ-1, with additional follow-up (data cutoff Feb 25, 2022) and data maturity beyond the interim analysis, are reported here. Efficacy was assessed in the full analysis set (all randomly assigned participants). Safety was assessed in the safety analysis set (all participants who received at least one dose of study treatment). The TOPAZ-1 study is registered with ClinicalTrials.gov, NCT03875235., Findings: From April 16, 2019, to Dec 11, 2020, 914 participants were enrolled, 685 of whom were randomly assigned (341 to the durvalumab plus gemcitabine-cisplatin group and 344 to the placebo plus gemcitabine-cisplatin group). 345 (50%) participants were male and 340 (50%) were female. Median follow-up at the updated data cutoff was 23·4 months (95% CI 20·6-25·2) in the durvalumab plus gemcitabine-cisplatin group and 22·4 months (21·4-23·8) in the placebo plus gemcitabine-cisplatin group. At the updated data cutoff, 248 (73%) participants in the durvalumab plus gemcitabine-cisplatin group and 279 (81%) participants in the placebo plus gemcitabine-cisplatin group had died (median overall survival 12·9 months [95% CI 11·6-14·1] vs 11·3 months [10·1-12·5]; hazard ratio 0·76 [95% CI 0·64-0·91]). Kaplan-Meier-estimated 24-month overall survival rates were 23·6% (95% CI 18·7-28·9) in the durvalumab plus gemcitabine-cisplatin group and 11·5% (7·6-16·2) in the placebo plus gemcitabine-cisplatin group. Maximum grade 3 or 4 adverse events occurred in 250 (74%) of 338 participants in the durvalumab plus gemcitabine-cisplatin group and 257 (75%) of 342 in the placebo plus gemcitabine-cisplatin group. The most common maximum grade 3 or 4 treatment-related adverse events were decreased neutrophil count (70 [21%] vs 86 [25%]), anaemia (64 [19%] vs 64 [19%]), and neutropenia (63 [19%] vs 68 [20%])., Interpretation: Durvalumab plus gemcitabine-cisplatin showed robust and sustained overall survival benefit with no new safety signals.

Silver (Ag) metal-based structures are promising building blocks for next-generation photonics and electronics owing to their unique characteristics, such as high reflectivity, surface plasmonic resonance effects, high electrical conductivity, and tunable electron transport mechanisms. However, Ag structures exhibit poor sustainability in terms of device performance because harsh chemicals, particularly S 2- ions present in the air, can damage their structures, lowering their optical and electrical properties. Here, the surface chemistry of Ag structures with (3-mercaptopropyl)trimethoxysilane (MPTS) ligands at room temperature and under ambient conditions is engineered to prevent deterioration of their optical and electrical properties owing to S 2- exposure. Regardless of the dimensions of the Ag structures, the MPTS ligands can be applied to each dimension (0D, 1D, and 3D). Consequently, highly sustainable plasmonic effects (Δλ < 2 nm), Fabry-Perot cavity resonance structures (Δλ < 2 nm), reflectors (ΔR Reflectance < 0.5%), flexible electrodes (ΔR electrical < 0.1 Ω), and strain gauge sensors (ΔGF < 1), even in S 2- exposing conditions is achieved. This strategy is believed to significantly contribute to environmental pollution reduction by decreasing the volume of electronic waste., (© 2024 Wiley‐VCH GmbH.)

Background: A laser-induced needle-free microjet injector was developed for rapid, high-speed drug delivery of microliters into the skin., Objective: This study evaluated the clinical rejuvenation effect of repeated dermal injections of the collagen simulator poly- dl -lactic acid (PDLA) using a laser-induced needle-free microjet injector., Methods: Five PDLA injection sessions using a laser-induced needle-free microjet injector were conducted in patients concerned about aging skin. Facial uplifting, darkness, redness, roughness, pore size, subjective satisfaction, and side effects were evaluated before each session and 4 weeks after treatment completion. Histological evaluation was also performed with immunohistochemical staining of collagen and elastic fibers., Results: The clinical results of 27 female patients were evaluated. The treatment resulted in a noticeable skin surface uplifting (0.711 ± 0.42 mm) and significant improvements in darkness ( p = .013), redness ( p = .009), and roughness ( p = .036), with no significant difference in the pore size ( p = .770). Patients were reported being satisfied with the overall therapeutic effects, despite mild and tolerable adverse effects. Histological findings revealed growth and thickening of collagen and elastic fibers, with marked increase in collagen I and III levels., Conclusion: Repeated dermal injections of PDLA using a laser-induced microjet injector offer excellent drug delivery, achieving high efficacy in skin rejuvenation, patient satisfaction, and safety., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Adipogenin (Adig) is an evolutionarily conserved microprotein and is highly expressed in adipose tissues and testis. Here, we identify Adig as a critical regulator for lipid droplet formation in adipocytes. We determine that Adig interacts directly with seipin, leading to the formation of a rigid complex. We solve the structure of the seipin/Adig complex by Cryo-EM at 2.98Å overall resolution. Surprisingly, seipin can form two unique oligomers, undecamers and dodecamers. Adig selectively binds to the dodecameric seipin complex. We further find that Adig promotes seipin assembly by stabilizing and bridging adjacent seipin subunits. Functionally, Adig plays a key role in generating lipid droplets in adipocytes. In mice, inducible overexpression of Adig in adipocytes substantially increases fat mass, with enlarged lipid droplets. It also elevates thermogenesis during cold exposure. In contrast, inducible adipocyte-specific Adig knockout mice manifest aberrant lipid droplet formation in brown adipose tissues and impaired cold tolerance.

Background: Neoadjuvant treatment (NAT) is standard for borderline resectable pancreatic cancer (BRPC). However, consensus is lacking on the optimal surgical timing for patients with BRPC undergoing NAT. The aim of this study was to investigate the long-term outcomes of patients undergoing NAT for BRPC and suggest optimal resection timing., Methods: Prospectively collected data for 282 patients with BRPC between January 2007 and December 2019 were retrospectively reviewed. There were 164 patients who underwent NAT followed by surgery, 45 for chemotherapy only, and 73 for upfront surgery. Among them, 150 patients who underwent R0 or R1 resection following NAT were investigated to identify prognostic factors., Results: Patients receiving NAT followed by surgery showed the best survival (median overall survival [OS]; NAT followed by surgery vs. upfront surgery vs. chemotherapy only; 35 vs. 23 vs. 16 months). In the NAT group, 54 (36.0%) patients received less than 3 months of NAT, 68 (45.3%) received ≥3, <6 months, and 28 (18.7%) received longer than 6 months. Patients receiving ≥3 months of NAT showed an improved OS compared to <3 months (median; not reached vs. 27 months). In the FOLFIRINOX group, patients who received more than eight FOLFIRINOX cycles showed a good prognosis (<6 vs. 6-7 vs. ≥8 cycles; median survival, 26 vs. 41 months vs. not-reached). However, >12 cycles did not carry a survival benefit compared to 8-11 cycles., Conclusion: The optimal resection timing following NAT is once a patient undergoes at least 3 months of neoadjuvant chemotherapy or at least eight FOLFIRINOX cycles., (© 2024 Japanese Society of Hepato‐Biliary‐Pancreatic Surgery.)

Identifying pan-tumor biomarkers that predict responses to immune checkpoint inhibitors (ICI) is critically needed. In the AMADEUS clinical trial (NCT03651271), patients with various advanced solid tumors were assessed for changes in intratumoral CD8 percentages and their response to ICI. Patients were grouped based on tumoral CD8 levels: those with CD8 <15% (CD8-low) received nivolumab (anti-PD-1) plus ipilimumab (anti-CTLA4) and those with CD8 ≥15% (CD8-high) received nivolumab monotherapy. 79 patients (72 CD8-low and 7 CD8-high) were treated. The disease control rate was 25.0% (18/72; 95% CI: 15.8-35.2) in CD8-low and 14.3% (1/7; 95% CI: 1.1-43.8) in CD8-high. Tumors from 35.9% (14/39; 95% CI: 21.8-51.4) of patients converted from CD8 <15% pretreatment to ≥15% after treatment. Multiomic analyses showed that CD8-low responders had an inflammatory tumor microenvironment pretreatment, enhanced by an influx of CD8 T cells, CD4 T cells, B cells, and macrophages upon treatment. These findings reveal crucial pan-cancer immunological features for ICI response in patients with metastatic disease., (© 2024 Tsimberidou et al.)

Ethylene oxide (E.O) is an epoxide compound, and it has been utilized as a sterilizer or production of ether compounds in several industries. Although the toxic effects of E.O on bacteria and mammals have been reported, its effects on male reproductive toxicity during sperm capacitation are not fully understood. Therefore, this study was designed to evaluate the effects of E.O exposure during sperm capacitation. Boar spermatozoa were treated with various E.O concentrations (0, 0.1, 1, 10, and 100 μМ). After exposure, sperm motility, motion kinematics, capacitation status, intracellular ATP levels, cell viability, expression levels of protein kinase A (PKA) activation, and tyrosine phosphorylation were evaluated. Results revealed that E.O exposure significantly decreased sperm motility, motion kinematics, and intracellular ATP levels but significantly increased the capacitated spermatozoa. In addition, the PKA activation and tyrosine phosphorylation were abnormally changed. According to our results, E.O may cause toxic effects on sperm function during capacitation, which induces male reproductive toxicity. Consequently, we suggest that male reproductive toxicity should be considered when using E.O., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: 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 [ 177 Lu]Lu-DOTA-TATE ( 177 Lu-Dotatate) treatment., Methods: 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 177 Lu-Dotatate plus intramuscular octreotide 30 mg long-acting repeatable (LAR) then octreotide 30 mg LAR every 4 weeks ( 177 Lu-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., Findings: 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 177 Lu-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 177 Lu-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 177 Lu-Dotatate group and 69 (95%) of 73 treated patients in the control group. There were no study drug-related deaths during the treatment period., Interpretation: First-line 177 Lu-Dotatate plus octreotide LAR significantly extended median progression-free survival (by 14 months) in patients with grade 2 or 3 advanced gastroenteropancreatic neuroendocrine tumours. 177 Lu-Dotatate should be considered a new standard of care in first-line therapy in this population., Funding: Advanced Accelerator Applications, a Novartis Company., Competing Interests: Declaration of interests SS reports support for the present work from Novartis; grants or contracts from Novartis; consulting fees from Ipsen, Novartis, and Camurus; and meeting attendance support from Ipsen and Novartis.

What Is This Summary About?: This summary describes the results from a phase 2 study called FOENIXCCA2. The study evaluated treatment with futibatinib in people with a rare form of advanced bile duct cancer called intrahepatic cholangiocarcinoma (or iCCA), where the tumors have changes in the structure of a gene called FGFR2. These changes include FGFR2 gene fusions. Bile duct cancer often returns after surgery or cannot be treated by surgery because the tumor has spread, so it requires treatment with chemotherapy. People live for a median of 1 year after their first chemotherapy treatment and 6 months after their second treatment. This study included people whose cancer had grown/spread after one or more chemotherapy treatments. The aims of the study were to see if futibatinib could shrink the size of tumors and stop the cancer from growing/spreading and to see how long people lived when treated with futibatinib. Clinicians also looked at side effects from taking futibatinib and at how it affected people's quality of life., What Were the Results?: Futibatinib treatment shrank tumors in over 80% of people who received treatment. Tumors shrank by at least 30% in 42% of people. Futibatinib stopped tumors from growing/spreading for a median of 9.7 months. People who took the medicine lived for a median of 21.7 months, and 72% of people were still alive after 1 year. Side effects from taking futibatinib were like those reported for similar medicines, and clinicians considered the side effects to be manageable by adjusting the dose of futibatinib or treating the side effects. Most people reported that their quality of life stayed the same or improved during the first 9 months of taking futibatinib., What Do the Results Mean?: The results support the use of futibatinib for treating people with advanced bile duct cancer. Based on the results of this study, futibatinib is now approved in the US, Europe, and Japan. Futibatinib is approved for treating adults with advanced bile duct cancer who have received previous treatment for their cancer, and whose tumors have a gene fusion or other change in the FGFR2 gene. Clinical Trial Registration: NCT02052778 (FOENIX-CCA2).

Background/Objectives : Immediate breast reconstruction surgery (BRS) often leads to significant postoperative pain, necessitating effective analgesia. This study aimed to compare the analgesic efficacy of patient-controlled analgesia (PCA) containing nefopam with that of PCA containing opioids alone in patients undergoing BRS. Methods : A prospective, double-blind, randomized controlled trial was conducted on 120 patients undergoing immediate BRS after mastectomy. Patients were randomly allocated to receive PCA with fentanyl alone (Group F: fentanyl 10 mcg/kg), fentanyl and nefopam (Group FN: fentanyl 5 mcg/kg + nefopam 1 mg/kg), or nefopam alone (Group N: nefopam 2 mg/kg). Pain intensity (expressed in VASr and VASm), opioid consumption, and opioid-related complications were assessed. Results : PCA with nefopam, either alone or in combination with opioids, demonstrated non-inferior analgesic efficacy compared to PCA with fentanyl alone. At 24 h postoperatively, the VASr scores were 2.9 ± 1.0 in Group F, 3.1 ± 1.2 in Group FN, and 2.8 ± 0.9 in Group N ( p = 0.501). At the same timepoint, the VASm scores were 4.1 ± 1.2 in Group F, 4.5 ± 1.5 in Group FN, and 3.8 ± 1.4 in Group N ( p = 0.129). Significant differences among the three groups were observed at all timepoints except for PACU in terms of the total opioid consumption ( p < 0.0001). However, there were no significant differences in opioid-related complications among the three groups. Conclusions : PCA with nefopam, whether alone or in combination with opioids, offers non-inferior analgesic efficacy compared to PCA with fentanyl alone in patients undergoing immediate BRS.

Background and Aims: We compared the safety and efficacy of bintrafusp alfa (BA) in combination with gemcitabine+cisplatin (GemCis), to those of GemCis alone, in patients with biliary tract cancer., Approach and Results: This randomized, double-blind, placebo-controlled, adaptive design phase 2/3 trial (NCT04066491) included adults who are treatment-naive with locally advanced/metastatic biliary tract cancer. Patients (N = 297) were randomized to receive an IV infusion of BA (2400 mg once/3 wk) plus GemCis (gemcitabine 1000 mg/m 2 +cisplatin 25 mg/m 2 on days 1 and 8/3 wk; 8 cycles) (BA group, n = 148) or placebo+GemCis (placebo group, n = 149). The primary end point was overall survival (OS). For adaptation analysis (phase 2-phase 3; data cutoff: May 20, 2021), efficacy was assessed in the first 150 patients who were antibiotic-naive when 80 progression-free survival events had occurred and ≥ 19 weeks of follow-up had been completed (BA, n = 73; placebo, n = 77). Median OS (95% CI) for the BA (11.5 mo [9.3-not estimable]) and placebo (11.5 mo [10.0-not estimable]) groups was comparable (hazard ration 1.23 [95% CI 0.66-2.28]; p = 0.7394); OS data maturity was 27.2% (41 events/151 patients). The most common grade ≥3 treatment-related adverse event was anemia (BA, 26.0%; placebo, 22.8%). Bleeding adverse events were reported more frequently in the BA group (28.8%) versus the placebo group (7.4%). Deaths within 60 days of the first dose were reported in 7.5% and 1.3% of patients in the BA and placebo groups, respectively., Conclusions: BA+GemCis did not provide a clinically meaningful benefit compared with GemCis alone as first-line treatment for biliary tract cancer, and the study was discontinued early (terminated: August 20, 2021)., (Copyright © 2024 The Author(s).

Background: Fibroblast growth factor receptor 2 (FGFR2) fusions and rearrangements are clinically actionable genomic alterations in cholangiocarcinoma (CCA). Pemigatinib is a selective, potent, oral inhibitor of FGFR1-3 and demonstrated efficacy in patients with previously treated, advanced/metastatic CCA with FGFR2 alterations in FIGHT-202 (NCT02924376). We report final outcomes from the extended follow-up period., Patients and Methods: The multicenter, open-label, single-arm, phase II FIGHT-202 study enrolled patients ≥18 years old with previously treated advanced/metastatic CCA with FGFR2 fusions or rearrangements (cohort A), other FGF/FGFR alterations (cohort B), or no FGF/FGFR alterations (cohort C). Patients received once-daily oral pemigatinib 13.5 mg in 21-day cycles (2 weeks on, 1 week off) until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) in cohort A assessed as per RECIST v1.1 by an independent review committee; secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety., Results: FIGHT-202 enrolled 147 patients (cohort A, 108; cohort B, 20; cohort C, 17; unconfirmed FGF/FGFR alterations, 2). By final analysis, 145 (98.6%) had discontinued treatment due to progressive disease (71.4%), withdrawal by patient (8.2%), or adverse events (AEs; 6.8%). Median follow-up was 45.4 months. The ORR in cohort A was 37.0% (95% confidence interval 27.9% to 46.9%); complete and partial responses were observed in 3 and 37 patients, respectively. Median DOR was 9.1 (6.0-14.5) months; median PFS and OS were 7.0 (6.1-10.5) months and 17.5 (14.4-22.9) months, respectively. The most common treatment-emergent AEs (TEAEs) were hyperphosphatemia (58.5%), alopecia (49.7%), and diarrhea (47.6%). Overall, 15 (10.2%) patients experienced TEAEs leading to pemigatinib discontinuation; intestinal obstruction and acute kidney injury (n = 2 each) occurred most frequently., Conclusions: Pemigatinib demonstrated durable response and prolonged OS with manageable AEs in patients with previously treated, advanced/metastatic CCA with FGFR2 alterations in the extended follow-up period of FIGHT-202., (Copyright © 2024 The Author(s).

Background: Palmoplantar pustulosis (PPP) and pompholyx are chronic diseases characterized by pustules and vesicles on the palms and soles. These disorders often have similar clinicopathological features, which lead to diagnostic difficulties. We aimed to investigate the expression patterns of keratins and involucrin in PPP and pompholyx using immunohistochemical staining., Methods: Skin biopsies from patients with PPP (n = 40) and pompholyx (n = 22) were immunohistochemically analyzed for Keratin 5, 9, 14, and involucrin expression., Results: K5 expression was higher in PPP than in pompholyx, with diffusely positive expression in the basal, spinous, and granular layers. K14 expression did not differ between groups. K9 expression was observed near the pompholyx vesicle (P = 0.014) and stratum spinosum (P < 0.001) but was almost absent around PPP pustules. Involucrin expression was diffused around the PPP pustules and partially around the pompholyx vesicles, but without statistical significance (P = 0.123). Involucrin expression was elevated in the basal layer of the PPP compared with that in the pompholyx (P = 0.023)., Conclusion: PPP and pompholyx exhibited distinctive differentiation in the expression of K5, K9, and involucrin., (© 2024 the International Society of Dermatology.)

For energy recovery, anaerobic digestion is applied to organic waste, such as livestock manure (LM) and food wastewater (FW). Digested sludge(DS), a residue from the anaerobic co-digestion of LM and FW, is another type of organic waste that can be converted into energy through pyrolysis. This study compared the pyrolysis characteristics of LM, FW, and DS. The product content varied with the pyrolysis temperature, rate of temperature increase, reaction time, and final reaction temperature. Gas production from FW and DS was similar; however, gas production from LM was low. As the pyrolysis temperature increased, the H 2 content increased, and the CO 2 content decreased, respectively. At 1000 °C, the H 2 content of LM increased to 45%, and FW produced the most gas but the lowest H 2 content. The H 2 /CO ratios of LM and FW ranged from 3.5 to 5.2, while those of DS ranged from 5.5 to 12.4, with the highest values. The carbon conversion rate was the highest for the gaseous products of LM (30-54%) and lowest for the gaseous products of digested sludge (26-36%). Conversely, the cold gas efficiency was the highest for the DS and lowest for the LM. Following anaerobic digestion, the DS generated less tar than the untreated LM and FW, showed higher efficiency in gas generation and gas properties, and exhibited a higher value as a char fuel., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: Trastuzumab deruxtecan is a HER2-directed antibody-drug conjugate approved by the US Food and Drug Administration and the European Medicines Agency for HER2-mutant non-small-cell lung cancer. Few treatment options exist for patients with HER2-mutant solid tumours beyond lung cancers. We investigated trastuzumab deruxtecan in metastatic solid tumours with specific activating HER2 mutations., Methods: In this open-label, phase 2, basket study done in 29 centres in Asia, Europe, and North America, we investigated trastuzumab deruxtecan (5·4 mg/kg every 3 weeks by intravenous infusion) in patients aged 18 years or older with unresectable or metastatic solid tumours with specific activating HER2 mutations, an Eastern Cooperative Oncology Group performance status of 0 or 1, and disease progression following previous treatment (previous HER2-targeted therapy was permitted) or with no satisfactory alternative treatment options. The primary endpoint was confirmed objective response rate by independent central review. Anti-tumour activity and safety were analysed in all patients who received at least one dose of trastuzumab deruxtecan. This trial is registered with ClinicalTrials.gov, NCT04639219, and is active but no longer recruiting., Findings: Between Dec 30, 2020, and Jan 25, 2023, 102 patients (62 [61%] female and 40 [39%] male; median age 66·5 years [IQR 58-72]; 51 [50%] White, two [2%] Black or African American, 38 [37%] Asian, and 11 [11%] did not have race information reported) with solid tumours with activating HER2 mutations received trastuzumab deruxtecan and were included in the anti-tumour activity and safety analyses sets. Patients had a median of three (IQR 2-4) previous treatment regimens. The median duration of follow-up was 8·61 months (IQR 3·71-12·68). The objective response rate by independent central review was 29·4% (95% CI 20·8-39·3; 30 of 102 patients). 52 (51%) patients had a treatment-emergent adverse event of grade 3 or worse; the most common events (in ≥5% of patients) were anaemia (16 [16%]) and neutrophil count decreased (eight [8%]). Drug-related treatment-emergent serious adverse events occurred in ten (10%) patients. Adjudicated drug-related interstitial lung disease or pneumonitis of any grade occurred in 11 patients (11%; three grade 1, five grade 2, one grade 3, and two grade 5); there were two (2%) cases of fatal adjudicated drug-related interstitial lung disease or pneumonitis., Interpretation: Trastuzumab deruxtecan showed anti-tumour activity and durable responses in heavily pretreated patients across multiple tumour types with activating HER2 mutations, with no new safety signals. Prespecified HER2 mutations might be targeted by HER2-directed antibody-drug conjugates and our findings support further investigation of trastuzumab deruxtecan in the pan-tumour setting., Funding: AstraZeneca and Daiichi Sankyo., Competing Interests: Declaration of interests BTL has served as an uncompensated advisor and consultant to Amgen, AstraZeneca, Boehringer Ingelheim, Bolt Biotherapeutics, Daiichi Sankyo, Genentech, and Lilly.

Purpose: This multicenter phase II basket trial investigated the efficacy, safety and pharmacokinetics of Debio 1347, an investigational, oral, highly selective, ATP-competitive, small molecule inhibitor of FGFR1-3, in patients with solid tumors harboring a functional FGFR1-3 fusion., Patients and Methods: Eligible adults had a previously treated locally advanced (unresectable) or metastatic biliary tract (cohort 1), urothelial (cohort 2) or other histologic cancer type (cohort 3). Debio 1347 was administered at 80 mg once daily, continuously, in 28-day cycles. The primary endpoint was the objective response rate (ORR). Secondary endpoints included duration of response, progression-free survival, overall survival, pharmacokinetics, and incidence of adverse events., Results: Between March 22, 2019 and January 8, 2020, 63 patients were enrolled and treated, 30 in cohort 1, four in cohort 2, and 29 in cohort 3. An unplanned preliminary statistical review showed that the efficacy of Debio 1347 was lower than predicted and the trial was terminated. Three of 58 evaluable patients had partial responses, representing an ORR of 5%, with a further 26 (45%) having stable disease (≥6 weeks duration). Grade ≥3 treatment-related adverse events occurred in 22 (35%) of 63 patients, with the most common being hyperphosphatemia (13%) and stomatitis (5%). Two patients (3%) discontinued treatment due to adverse events., Conclusions: Debio 1347 had manageable toxicity; however, the efficacy in patients with tumors harboring FGFR fusions did not support further clinical evaluation in this setting. Our transcriptomic-based analysis characterized in detail the incidence and nature of FGFR fusions across solid tumors.
