Efficacy and safety of gemcitabine/nab-paclitaxel combined with anlotinib and PD-1 inhibitors as a first-line treatment for advanced pancreatic cancer

ObjectiveTo investigate the clinical efficacy and adverse reactions of gemcitabine/nab-paclitaxel (AG regimen) combined with anlotinib and PD-1 inhibitors as a first-line treatment for advanced pancreatic cancer (PC). MethodsData of 52 patients with advanced PC who were treated in the Affiliated Hospital of Xuzhou Medical University (Xuzhou, China) between August 2019 and March 2023 were retrospectively analyzed. According to the treatment regimen, patients were divided into two groups, including 27 patients in the chemotherapy group (AG regimen) and 25 patients in the combined treatment group (AG regimen combined with anlotinib and PD-1 inhibitors). Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse reactions were compared between the two groups. The survival curves of the two groups were drawn using the Kaplan-Meier method, and the differences in PFS and OS between the two groups were compared by the log-rank test. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors influencing prognosis. ResultsThe median OS and PFS in the combined treatment group were significantly longer than those in the chemotherapy group (OS, 12.8 vs. 7.9 months, P = 0.005; PFS, 5.6 vs. 4.4 months, P = 0.003). There was no significant difference in ORR between the two groups (32.0 % vs. 25.9 %, P = 0.629), and DCR in the combined treatment group was significantly better than that in the chemotherapy group (84.0 % vs. 59.3 %, P = 0.049). Grade 1–2 adverse reactions were predominant in both groups, and no adverse reaction-related deaths occurred. ConclusionCompared with chemotherapy alone, AG regimen combined with anlotinib and PD-1 inhibitors exhibited to have a higher efficacy for the first-line treatment of advanced PC, and the adverse reactions were also controllable.

Nab-paclitaxel plus S-1 versus nab-paclitaxel plus gemcitabine in patients with advanced pancreatic cancer: a multicenter, randomized, phase II study.

Encouraging antitumor activity of nab-paclitaxel plus S-1 (AS) has been shown in several small-scale studies. This study compared the efficacy and safety of AS versus standard-of-care nab-paclitaxel plus gemcitabine (AG) as a first-line treatment for advanced pancreatic cancer (PC). In this multicenter, randomized, phase II trial, eligible patients with unresectable, locally advanced, or metastatic PC were recruited and randomly assigned (1:1) to receive AS (nab-paclitaxel 125mg/m2 on days 1 and 8; S-1 twice daily on days 1 through 14) or AG (nab-paclitaxel 125mg/m2 on days 1 and 8; gemcitabine 1000mg/m2 on days 1 and 8) for 6 cycles. The primary endpoint was progression-free survival (PFS). Between July 16, 2019, and September 9, 2022, 62 patients (AS, n = 32; AG, n = 30) were treated and evaluated. With a median follow-up of 8.36 months at preplanned interim analysis (data cutoff, March 24, 2023), the median PFS (8.48 vs 4.47 months; hazard ratio [HR], 0.402; P = .002) and overall survival (OS; 13.73 vs 9.59 months; HR, 0.226; P < .001) in the AS group were significantly longer compared to the AG group. More patients had objective response in the AS group than AG group (37.50% vs 6.67%; P = .005). The most common grade 3-4 adverse events were neutropenia and leucopenia in both groups, and gamma glutamyl transferase increase was observed only in the AG group. The first-line AS regimen significantly extended both PFS and OS of Chinese patients with advanced PC when compared with the AG regimen, with a comparable safety profile.

Combined Efficacy of Nimotuzumab and Gemcitabine on the Treatment of Advanced Pancreatic cancer.

We sought to investigate whether the addition of nimotuzumab to gemcitabine would improve the treatment efficacy of advanced pancreatic cancer. This retrospective analysis involved a total of 98 hospitalized patients harboring advanced pancreatic cancer. Depending on the specific treatment, patients were divided into study groups and control groups. The clinical efficacy, adverse reactions, and follow-up results of the 2 groups were compared, and the physical status, CA724, CA19-9, and CEA levels before and after treatment were monitored and recorded. After treatment, PR ratio, SD ratio, ORR, and DCR in the study group were significantly higher than those in the control group, and PD ratio was significantly lower than that in the control group (P < 0.05) the KPS score after treatment in the study group was markedly higher than that of the control group (P < 0.05). After treatment, however, significantly lower levels of the 3 indicators were observed when compared with the control group (P < 0.05). Our study highlights a more superior combined efficacy of nimotuzumab and gemcitabine than the control regimen, exhibiting improved survival and reduced levels of CA724, CA19-9, and CEA in patients with advanced pancreatic cancer.

Trends in the treatment of advanced pancreatic cancer.

Pancreatic cancer (PC) has the poorest prognosis among digestive cancers; only 15-20% of cases are resectable at diagnosis. This review explores multidisciplinary treatments for advanced PC, emphasizing resectability classification and treatment strategies. For locally advanced unresectable PC, systemic chemotherapy using modified FOLFIRINOX and gemcitabine with albumin-bound paclitaxel is standard, while the role of chemoradiation is debated. Induction chemotherapy followed by chemoradiation may be a promising therapy. Conversion surgery after initial chemotherapy or chemoradiotherapy offers favorable survival, however criteria for conversion need further refinements. For metastatic PC, clinical trials using immune checkpoint inhibitors and molecular targeted therapies are ongoing. Multidisciplinary approaches and further research are crucial for optimizing treatment and improving outcomes for advanced PC.

The efficacy of coaxial percutaneous iodine-125 seed implantation combined with arterial infusion chemotherapy for advanced pancreatic cancer: a randomized clinical trial

Background This study aimed to evaluate the clinical efficacy of coaxial percutaneous Iodine-125 (125I) seed implantation in combination with arterial infusion chemotherapy for the treatment of advanced pancreatic cancer (PC) through a randomized controlled trial. Methods A total of 101 patients with advanced PC were randomized into two groups: control group treated with systemic intravenous chemotherapy and experimental group that received 125I seed implantation in combination with arterial infusion chemotherapy. Outcomes, including tumor control, abdominal pain relief, and survival time were compared between these two groups (Trial Registration No. KYKT2018-65). Results Pretreatment abdominal pain scores were comparable between the two groups, whereas the abdominal pain scores at 1- and 3-month post-treatment were significantly lower in the control group than those in the experimental group (1-month: 3.74 ± 1.54 vs. 4.48 ± 1.46, p = .015; 3-month: 3.64 ± 2.21 vs. 5.40 ± 1.56, p < .001). At 3-month post-treatment, computed tomography (CT) scan revealed a significantly higher disease control rate in the experimental group than that in the control group (94.0% vs. 74.5%, p = .007). The median survival time in the experimental group was significantly longer than that in the control group (15-month vs. 9-month, p < .001). Conclusion The combination of coaxial percutaneous 125I seed implantation with arterial infusion chemotherapy could significantly alleviate abdominal pain, improve tumor control rates, and prolong survival time in patients with advanced PC.

Clinical efficacy and safety of erlotinib combined with chemotherapy in the treatment of advanced pancreatic cancer: A meta-analysis.

Advanced pancreatic cancer is resistant to chemotherapeutic drugs, resulting in limited treatment efficacy and poor prognosis. Combined administration of the chemotherapeutic gemcitabine and erlotinib is considered a potential first-line treatment for advanced pancreatic cancer. However, their comparative benefits and potential risks remain unclear. To assess the clinical efficacy and safety of erlotinib combined with other chemotherapy regimens for the treatment of advanced pancreatic cancer. Literature on the clinical efficacy and safety of erlotinib combined with chemotherapy for advanced pancreatic cancer was retrieved through an online search. The retrieved literature was subjected to a methodological qualitative assessment and was analyzed using the RevMan 5.3 software. Ten randomized controlled trials involving 2444 patients with advanced pancreatic cancer were included in the meta-analysis. Compared with chemotherapeutic treatment, erlotinib combined with chemotherapy significantly prolonged the progression-free survival time of pancreatic cancer patients [hazard ratio (HR) = 0.78, 95%CI: 0.66-0.92, P = 0.003]. Meanwhile, the overall survival (HR= 0.99, 95%CI: 0.72-1.37, and P = 0.95) and disease control rate (OR = 0.93, 95%CI: 0.45-0.91, P = 0.84) were not significantly favorable. In terms of safety, the erlotinib and chemotherapy combination was associated with a significantly higher risk of diarrhea (OR = 3.59, 95%CI: 1.63-7.90, P < 0.05) and rash (OR = 3.63, 95%CI: 1.64-8.01, P < 0.05) compared with single-agent chemotherapy. Moreover, the risk of vomiting (OR = 1.27, 95%CI: 0.62-2.59, P = 0.51), regurgitation/anorexia (OR = 1.61, 95%CI: 0.25-10.31, P = 0.62), and infection (OR = 0.72, 95%CI: 0.28-1.87, P = 0.50) were not significant in either group. Compared with a single chemotherapeutic modality, erlotinib combined with gemcitabine can prolong progression-free survival in pancreatic cancer, but does not improve survival benefit or disease control rate, and can increase the risk of diarrhea and rash.

WT1 Cancer Vaccine in Advanced Pancreatic Cancer: A Systematic Review.

Advanced pancreatic cancer is one of the prominent contributors to cancer-related mortality globally. Chemotherapy, especially gemcitabine, is generally used for the treatment of advanced pancreatic cancer. Despite the treatment, the fatality rate for advanced pancreatic cancer is alarmingly high. Thus, the dire need for better treatment alternatives has drawn focus to cancer vaccinations. The Wilms tumor gene (WT1), typically associated with Wilms tumor, is found to be excessively expressed in some cancers, such as pancreatic cancer. This characteristic feature is harvested to develop cancer vaccines against WT1. This review aims to systematically summarize the clinical trials investigating the efficacy and safety of WT1 vaccines in patients with advanced pancreatic cancer. An extensive literature search was conducted on databases Medline, Web of Science, ScienceDirect, and Google Scholar using the keywords "Advanced pancreatic cancer," "Cancer vaccines," "WT1 vaccines," and "Pulsed DC vaccines," and the results were exclusively studied to construct this review. WT1 vaccines work by introducing peptides from the WT1 protein to trigger an immune response involving cytotoxic T lymphocytes via antigen-presenting cells. Upon activation, these lymphocytes induce apoptosis in cancer cells by specifically targeting those with increased WT1 levels. WT1 vaccinations, which are usually given in addition to chemotherapy, have demonstrated clinically positive results and minimal side effects. However, there are several challenges to their widespread use, such as the immunosuppressive nature of tumors and heterogeneity in expression. Despite these limitations, the risk-benefit profile of cancer vaccines is encouraging, especially for the WT1 vaccine in the treatment of advanced pancreatic cancer. Considering the fledgling status of their development, large multicentric, variables-matched, extensive analysis across diverse demographics is considered essential.

Efficacy of continuous arterial perfusion chemotherapy combined with transarterial chemoembolization regional arterial thermal perfusion in the treatment of pancreatic cancer with liver metastases

Abstract Background The aim of the study was to investigate the efficacy of continuous transcatheter arterial infusion chemotherapy combined with transarterial chemoembolization (TACE) for the treatment of advanced pancreatic cancer with liver metastasis. Methods Sixty patients with advanced pancreatic cancer and liver metastases were enrolled in this study. In the treatment group, 31 patients underwent continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial thermal perfusion, whereas 29 patients included in the control group received intravenous chemotherapy with gemcitabine and S-1. All patients received maintenance chemotherapy with S-1 after 4 cycles of the study regimen. Treatment efficacy, quality of life, survival, and toxicity were evaluated. Results Efficacy was better in the treatment group than in the control group, as reflected by the objective remission, partial remission, and disease progression rates (all P &lt; 0.05). The Eastern Cooperative Oncology Group and Numerical Rating Scale pain scores were also higher in the treatment group (both P &lt; 0.05). In survival analysis, the 1-year overall survival rates in the treatment and control groups were 64.516% and 10.345%, respectively, whereas the median overall survival times were 16 and 6 months, respectively (both P &lt; 0.05). The 6-month progression-free survival rates in the treatment and control groups were 77.419% and 13.790%, respectively, and the median progression-free survival times were 12 and 3 months, respectively (both P &lt; 0.05). The rates of hematological and nonhematological toxicological adverse effects were also lower in the treatment group (both P &lt; 0.05). Although the rate of liver dysfunction was higher in the treatment group, this finding had no adverse effects on prognosis. Conclusions Continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial perfusion chemotherapy resulted in better efficacy and safety outcomes in patients with pancreatic cancer and liver metastasis, suggesting its utility as a reference method for the clinical treatment of advanced pancreatic cancer.

The real-world study of the clinical characteristics, diagnosis, and treatment of advanced pancreatic cancer in China

Objective: Real-world diagnostic and treatment data for pancreatic cancer in China are lacking. As such, the present study investigated the clinical characteristics, diagnosis, and treatment of advanced pancreatic cancer (including locally advanced and metastatic disease) in the Hospital-based Advanced Pancreatic Cancer Cohort in China of the China Pancreas Data Center database. Methods: A total of 5349 Chinese patients with advanced pancreatic cancer were identified from a database. The entire course of real-world pancreatic cancer management was analyzed. Results: The proportion of patients with advanced pancreatic cancer was higher among males than females (62.4% vs 37.6%, respectively). Patients typically had a history of hypertension (30.8%), diabetes (21.6%), and cholangitis (20.2%). Abdominal pain (51.6%), abdominal distension (27.1%), jaundice (20.1%), and weight loss (16.3%) were the main symptoms observed in patients with advanced pancreatic cancer in this cohort. Serum carbohydrate antigen (CA)19-9 is one of the most common tumor markers. In the present study, 2562 patients underwent first-line therapy. The median progression-free survival (PFS) for patients undergoing first-line therapy was 4.1 months. The major options for first-line therapy included gemcitabine (GEM) plus S-1 (GS/X) (23.4%), nab-paclitaxel plus GEM (AG) (18.1%), oxaliplatin, irinotecan, and leucovorin-modulated fluorouracil (FOLFIRINOX; 11.9%), nab-paclitaxel plus S-1 (AS) (8.9%), and GEM combined with oxaliplatin/cisplatin (GEMOX/GP) (7.6%). The AS and GS/X regimens were associated with the highest PFS rates. Conclusion: This is the first study to report multicenter, real-world data regarding advanced pancreatic cancer in China. Results revealed that real-world treatment options differed from guideline recommendations, and PFS was shorter than that in previously reported data. Improving intelligent follow-up systems and standardizing diagnosis and treatment of pancreatic cancer is recommended.

Feasibility of 125I brachytherapy combined with arterial infusion chemotherapy in patients with advanced pancreatic cancer.

To evaluation the feasibility of Iodine-125 (¹²5I) brachytherapy combined with arterial infusion chemotherapy in patients with advanced pancreatic cancer. A total of 72 cases with Stage III and IV were retrospectively reviewed. 23 cases receiving 125I brachytherapy were classified as Group A. 27 cases receiving arterial infusion chemotherapy (gemcitabine + cisplatin, GP) were classified as Group B and 22 cases receiving 125I brachytherapy combined with arterial infusion chemotherapy (GP) were classified as Group C. The evaluated indications were local control rate, survival rate, carbohydrate antigen 19-9, pain relief, and Karnofsky physical scores. Analysis of Variancep, Pearson chi-square test and Kaplan-Meier curves were used for analysis. The local control rate of group A and group C was significantly higher than group B (P < .001). Pearson chi-square test showed statistical difference of the 3 groups (χ2 = 12.969, P = .044). The median survival of group A,B and C was 9 months, 6 months and 13 months, respectively. The survival time of group C was significantly higher than group B (χ2 = 5.403, P = .020). The Log rank test showed statistical difference in the survival curve of the 3 groups (χ2 = 6.501, P = .039). The difference of carbohydrate antigen 19-9 decline percentage between group B and C group was statistically significant (χ2 = 5.959, P = .015). Patients in group A and group C relieved form pain after treatment with statistically significant (P < .001). Pain relief was much more effective in patients who received 125I brachytherapy. Karnofsky physical scores after treatment were statistically higher than those before treatment in each group (P < .001). 125I brachytherapy maybe one of the effective, safe and feasible alternative treatment of advanced pancreatic cancer. ¹²5I brachytherapy combined with arterial infusion chemotherapy was effective in the treatment of advanced pancreatic cancer.

Systemic treatment for advanced pancreatic cancer.

Pancreatic cancer is a deadly disease with an extremely poor 5-year survival rate due to treatment resistance and late-stage detection. Despite numerous years of research and pharmaceutical development, these figures have not changed. Treatment options for advanced pancreatic cancer are still limited. This illness is typically detected at a late stage, making curative surgical resection impossible. Chemotherapy is the most commonly utilized technique for treating advanced pancreatic cancer but has poor efficacy. Targeted therapy and immunotherapy have made significant progress in many other cancer types and have been proven to have extremely promising possibilities; these therapies also hold promise for pancreatic cancer. There is an urgent need for research into targeted treatment, immunotherapy, and cancer vaccines. In this review, we emphasize the foundational findings that have fueled the therapeutic strategy for advanced pancreatic cancer. We also address current advancements in targeted therapy, immunotherapy, and cancer vaccines, all of which continue to improve the clinical outcome of advanced pancreatic cancer. We believe that clinical translation of these novel treatments will improve the low survival rate of this deadly disease.

Gemcitabine, Docetaxel, Capecitabine, Cisplatin, Irinotecan as First-line Treatment for Metastatic Pancreatic Cancer.

Treatment of advanced pancreatic cancer with a single therapeutic at a maximal dose has been largely ineffective at increasing survival. Combination therapies are commonly studied but often limited by toxicity. We previously showed that low-dose multiagent therapy with gemcitabine, docetaxel (taxotere), capecitabine (xeloda), and cisplatin (GTX-C) was safe, well tolerated, and effective (NCT01459614). Here, we hypothesize that adding irinotecan to GTX-C may improve survival with minimal toxicity. Patients with treatment-naïve metastatic pancreatic adenocarcinoma were treated with gemcitabine, docetaxel (taxotere), capecitabine (xeloda), cisplatin, and irinotecan (GTX-CI). Treatment consisted of capecitabine 500 mg twice daily on days 1-14 and gemcitabine 300 to 500 mg/m2, docetaxel 20 mg/m2, cisplatin 15 to 20 mg/m2, and irinotecan 20 to 60 mg/m2 on days 4 and 11 of a 21-day cycle. The primary objective was 9-month overall survival (OS). Secondary objectives included response rate (RR), disease control rate (DCR), progression-free survival (PFS), and OS. The regimen was well tolerated. The recommended phase II dose was gemcitabine 500 mg/m2, docetaxel 20 mg/m2, capecitabine 500 mg po bid, cisplatin 20 mg/m2, and irinotecan 20 mg/m2. Median follow-up in phase II was 11.02 months (2.37-45.17). Nine-month OS rate was 57% [95% confidence interval (CI): (41-77)]. RR was 57% [95% CI: (37-75) 50% PR and 7% CR]. DCR was 87% [95% CI: (69-96)]. Median OS and PFS were 11.02 [95% CI: (8.54-21.09)] and 8.34 [95% CI: (6.34-NA)] months, respectively. The addition of irinotecan to GTX-C was safe and well tolerated. While the study did not meet its primary objective, the responses were clinically meaningful using a well-tolerated regimen. We aimed to optimize the previously reported efficacious regimen of low-dose multiagent therapy with GTX-C for the treatment of metastatic pancreatic ductal adenocarcinoma by adding irinotecan. The primary objective was not met, but GTX-CI was well tolerated. The RR of 57%, median PFS of 8.3 months, median OS of 11 months, and 36-month OS rate of 19% suggest clinical benefit. Further optimization of this regimen is warranted.

NALIRIFOX vs FOLFIRINOX vs gemcitabine plus nab-paclitaxel as first-line treatment of advanced pancreatic cancer: An individual patient data pooled analysis of phase 3 registration trials.

e16262 Background: The NAPOLI-3 trial showed the superiority of the NALIRIFOX regimen over the combination of gemcitabine and nab-Paclitaxel (GemNabP) as first-line treatment (1LTx) of advanced pancreatic cancer (PDAC), thus being candidate as a reference regimen in this setting. However, a comparison with the FOLFIRINOX regimen has not yet been performed. Methods: We performed a pooled analysis of phase III trials that defined FOLFIRINOX, NALIRIFOX and GemNabP as optimal 1LTx options in advanced PDAC. Individual patient outcomes were retrieved from Kaplan Meier plots of each trial, and analysed after assessment of data reconstruction accuracy. Progression free survival (PFS) and overall survival (OS) were compared between the three different arms, using Cox proportional hazard models including each trial as a random effect variable to account for inter-trial variability. Overall response rates (ORR) and Grade 3 or 4 (G3/4) toxicity rates were also compared. Results: A total of 1372 patients treated with FOLFIRINOX (n=171, 12), NALIRIFOX (n=383, 28) and GemNabP (n=818, 60) were included. Median PFS was significantly longer in patients treated with NALIRIFOX (7.4 months) as compared to FOLFIRINOX [6.4 months, HR 1.48 (95% CI 1.21 - 1.82), p&lt;.001] and GemNabP [5.6 months, HR 1.45 (95% CI 1.24 - 1.70), p = p&lt;.001]. NALIRIFOX also provided significantly higher ORR [42% vs 32% (FOLFIRINOX) vs 29% (GemNabP), p&lt;.001]. GemNabP was associated with poorer OS [9.2 months, HR 1.25 (95% CI 1.07 - 1.46), p=0.005], while no significant difference was observed between FOLFIRINOX [11.1 months, HR 1.12, (95% CI 0.88 - 1.43), p=0.344] and NALIRIFOX (11.1 months). Among G3/4 events, NALIRIFOX was associated with higher rates of diarrhea [p&lt;.001] and lower rates of peripheral neuropathy, thrombocytopenia and neutropenia [p&lt;.001], though with no difference in febrile neutropenia occurrence [p=0.158]. Conclusions: NALIRIFOX may provide superior ORR and PFS as compared to FOLFIRINOX and GemNabP as 1LTx of advanced PDAC, though with higher gastrointestinal toxicities and no difference in OS compared to FOLFIRINOX. Careful patient selection, drug costs consideration and direct comparison between FOLFIRINOX and NALIRIFOX is warranted. [Table: see text]

Efficacy and safety of apatinib combined with radiotherapy in the treatment of advanced pancreatic cancer: a meta-analysis

ObjectiveAt present, pancreatic cancer (PC) has a high morbidity and mortality rate and a poor prognosis. The aim of this article was to study the efficacy and safety of apatinib combined with radiotherapy in the treatment of advanced PC.MethodsThe PubMed, Cochrane Library, Embase, Wanfang, CNKI, VIP, and CBM databases were searched by computer to identify studies on the application of apatinib in patients with advanced PC. The patients in the included study were divided into an observation group (apatinib combined with radiotherapy) and a control group (radiotherapy only), and meta-analysis was performed for each outcome with Revman 5.4 software. This study was successfully registered on the PROSPERO website, and the registration number is CRD: 42,022,384,056 (available at https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=384056).ResultsA total of 7 randomized controlled trials (RCTs) with 428 patients were included, including 215 in the observation group and 213 in the control group. Compared with the control group, the observation group showed a greater objective response rate [OR = 3.26, 95% CI (2.18, 4.87), P < 0.0001], disease control rate [OR = 5.04, 95% CI (3.12, 8.12), P < 0.0001], complete response rate [OR = 3.87, 95% CI (1.51, 9.88), P = 0.005], and partial response rate [OR = 2.43, 95% CI (1.63, 3.61), P < 0.001], The 1-year survival rate [OR = 2.39, 95% CI (1.15, 4.96), P < 0.05], 2-year survival rate [OR = 2.41, 95% CI (1.03, 5.61), P < 0.05], progression-free survival time [MD = 1.17, 95% CI (0.37, 1.96), P < 0.05], overall survival time [MD = 1.47, 95% CI (0.13, 2.80), P < 0.05], while the stability rate [OR = 1.14, 95% CI (0.72, 1.81), P = 0.58] and various complications were not significantly different between the two groups.ConclusionApatinib combined with radiotherapy was more effective than radiotherapy alone in the treatment of advanced pancreatic cancer (PC), and apatinib had acceptable safety. However, since our study was limited by the quantity and quality of the included studies, we look forward to more large-sample, multicentre, and high-quality RCTs in the future to verify the conclusions.

LDE-paclitaxel in second or later lines in advanced pancreatic cancer: A phase I trial.

e16298 Background: Nanoparticles have been studied in association with chemotherapy, with objective of increasing the concentration of the drug in neoplastic cells and, thus, increasing its antitumor action. Nab-paclitaxel is a well-known nanotechnology association between paclitaxel and albumin and can be used in the treatment of advanced pancreatic cancer. LDE-Paclitaxel is a combination of paclitaxel and a synthetic molecule of low-density lipoprotein (LDE). It was previously evaluated in patients with gynaecological malignancies undergoing third-line treatment and showed higher rates of disease control than conventional regimens described in the literature. Our objective was to evaluate the efficacy of LDE-paclitaxel in the treatment of advanced pancreatic cancer (stage III and IV) in second or third line of therapy. Methods: This was a prospective phase I/II, single-arm study, in which we delivered LDE-Paclitaxel at a weekly dose of 85mg/m² to patients with pancreatic adenocarcinoma in second or third-line. The patients must had been through treatment of at least one standard chemotherapy scheme. Results: From October 2020 to November 2021, nine patients with advanced pancreatic adenocarcinoma were enrolled in this prospective, single-arm, phase 1/2 study in which we offered LDE-Paclitaxel at a dose of 85mg/m² intravenously, after progression to gemcitabine. During this period, patients underwent a maximum of 5 cycles, with no need to reduce the medication dose in any of the cycles, for any of the patients. LDE-paclitaxel presented mostly grade 1 and 2 toxicities, mainly anaemia and neuropathy; Grade 3 toxicity was presented by only 1 patient, which was acute kidney injury. Median overall patient survival was 20.14 months, and patient survival after enrolment in the study and initiation of LDE-paclitaxel use was close to 5 months, with no decline in the assessed quality of life indices. Conclusions: LDE-paclitaxel appears to be more tolerable, viable and less toxic than other standard chemotherapy in this setting. Our results suggest that LDE-paclitaxel could be a therapeutic possibility for patients with metastatic pancreatic cancer. For a better evaluation, further studies would be necessary, to obtain more data on the use of this medication in clinical practice and for a better understanding of other important outcomes.
