A Randomized, Open-Label, Safety and Exploratory Efficacy Study of Kanglaite Injection (KLTi) plus Gemcitabine versus Gemcitabine in Patients with Advanced Pancreatic Cancer.

ABSTRACT: Background: This study was designed to assess the safety and preliminary efficacy of KLTi plus gemcitabine in patients with locally advanced or metastatic pancreatic cancer. Methods: In a randomized, open-label study, patients with locally advanced or metastatic pancreatic cancer were randomized 2:1 to receive KLTi plus gemcitabine or gemcitabine monotherapy. Three sequential cohorts were tested at 30 g/day, 50 g/day, and 30 g/day. Gemcitabine was administered at 1000 mg/m2 on days 1, 8 and 15 of each 28 day cycle. KLTi was administered on days 1-5, 8-12, and 15-19 of each 28 day cycle. Patients received study treatment until disease progression. The primary endpoint was progression-free survival in the ITT population. Safety evaluation was based on patients who received any study treatment. ClinicalTrials.gov identifier NCT00733850. Results: Eighty-five patients were randomized including 41 (28:13) in Cohort 1, 18 (12:6) in Cohort 2, and 26 (17:9) in Cohort 3. Due to a different dose and/or shift in patient populations in Cohort 2 and 3, efficacy data for the 30 gm dose are presented in this manuscript for Cohort 1 alone, and for the combination of Cohort 1+3. The 30 gm KLTi + gemcitabine group had a statistically significant improvement in progression-free survival (PFS) as assessed by blinded independent radiology review in the ITT population, with a median of 112 days, versus 58 days in the gemcitabine group (HR 0.50; 95% CI: 0.27, 0.92), p = 0.0240. The incidence rates of TEAEs, CTCAE Grade 3 or higher TEAEs, and SAEs were similar between the two arms. There were no deaths related to KLTi + gemcitabine treatment. Conclusion: Kanglaite Injection (30 g/day) plus a standard regimen of gemcitabine demonstrated encouraging clinical evidence of anti-neoplastic activity and a well-tolerated safety profile.

Project description:BackgroundKanglaite (KLT) injection, a kind of Chinese medicine, is considered a promising complementary therapeutic option for malignant cancer treatment. This study aimed to systematically investigate the efficacy and safety of the combination of KLT injection and radiochemotherapy for the treatment of advanced pancreatic cancer (PC).MethodsStudies were identified by searching Cochrane Library, Web of Science, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biological Medicine Database (CBM), Wanfang database and Chinese Scientific Journal Database (VIP) before October 2018. The primary reported outcomes including efficacy, quality of life (QoL), and adverse events were systematically evaluated.ResultsData from 16 trials with 960 patients with advanced PC were included. Compared with radiochemotherapy alone, the combination of KLT injection and radiochemotherapy significantly improved the 1-year overall survival (OS, odds ratio [OR] = 2.58 95% CI: 1.12-5.93 P = .03), overall response (ORR, OR = 2.16 95% CI: 1.58-2.94 P <.00001) and disease control rates (DCR, OR = 2.50 95% CI: 1.84-3.38 P <.00001). The QoL of patients, who received a combination of radiochemotherapy and KLT injection, also improved compared with radiochemotherapy treatment alone as indicated by the increased quality of life improved rate (QIR, OR = 3.68 95%CI: 2.36-5.75 P <.00001), pain relief rate (PRR, OR = 3.70 95% CI: 2.23-6.14 P <.00001) and weight gain rate (WGR, OR = 3.69 95% CI: 2.22-6.13 P <.00001). Adverse events related to radiochemotherapy including gastrointestinal side effects, nephrotoxicity, leukopenia, thrombocytopenia, and myelosuppression were alleviated (P <.05) when KLT was injected to patients with PC.ConclusionsEvidence from the Meta-analysis suggested that the combinational treatment of radiochemotherapy and KLT injection is more effective in advanced PC treatment than radiochemotherapy alone. Additionally, the combination therapy improved QoL of the patients. KLT injection can alleviate the adverse effects associated with the radiochemotherapy.

Project description:BackgroundLipusu is the first commercialized liposomal formulation of paclitaxel and has demonstrated promising efficacy against locally advanced lung squamous cell carcinoma (LSCC) in a small-scale study. Here, we conducted a multicenter, randomized, phase 3 study to compare the efficacy and safety of cisplatin plus Lipusu (LP) versus cisplatin plus gemcitabine (GP) as first-line treatment in locally advanced or metastatic LSCC.MethodsPatients enrolled were aged between 18 to 75 years, had locally advanced (clinical stage IIIB, ineligible for concurrent chemoradiation or surgery) or metastatic (Stage IV) LSCC, had no previous systemic chemotherapy and at least one measurable lesion as per the Response Evaluation Criteria in Solid Tumors (version 1.1) before administration of the trial drug. The primary endpoint was progression-free survival (PFS). The secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety profiles. To explore the possible predictive value of plasma cytokines for LP treatment, plasma samples were collected from the LP group at baseline and first efficacy evaluation time and were then subjected to analysis by 45-Plex ProcartaPlex Panel 1 to detect the presence of 45 cytokines using the Luminex xMAP technology. The correlation between treatment outcomes and dynamic changes in the levels of cytokines were evaluated in preliminary analyses.ResultsThe median duration of follow-up was 15.4 months. 237 patients in the LP group and 253 patients in the GP group were included in the per protocol set (PPS). In the PPS, the median PFS was 5.2 months versus 5.5 months in the LP and GP group (hazard ratio [HR]: 1.03, P = 0.742) respectively. The median OS was 14.6 months versus 12.5 months in the LP and GP group (HR: 0.83, P = 0.215). The ORR (41.8% versus 45.9%, P = 0.412) and DCR (90.3% versus 88.1%, P = 0.443) were also similar between the LP and GP group. A significantly lower proportion of patients in the LP group experienced adverse events (AEs) leading to treatment interruptions (10.9% versus 26.4%, P < 0.001) or treatment termination (14.3% versus 23.1%, P = 0.011). The analysis of cytokine levels in the LP group showed that low baseline levels of 27 cytokines were associated with an increased ORR, and 15 cytokines were associated with improved PFS, with 14 cytokines, including TNF-α, IFN-γ, IL-6, and IL-8, demonstrating an overlapping trend.ConclusionThe LP regimen demonstrated similar PFS, OS, ORR and DCR as the GP regimen for patients with locally advanced or metastatic LSCC but had more favorable toxicity profiles. The study also identified a spectrum of different cytokines that could be potentially associated with the clinical benefit in patients who received the LP regimen.

Project description:BackgroundImmune checkpoint inhibitors monotherapy has been studied in patients with advanced biliary tract cancer (BTC). The aim of this study was to assess the efficacy and safety of camrelizumab, plus gemcitabine and oxaliplatin (GEMOX) as first-line treatment in advanced BTC and explored the potential biomarkers associated with response.MethodsIn this single-arm, open-label, phase II study, we enrolled stage IV BTC patients. Participants received camrelizumab (3 mg/kg) plus gemcitabine (800 mg/m2) and oxaliplatin (85 mg/m2). Primary endpoints were 6-month progression-free survival (PFS) rate and safety. Secondary endpoints were objective response rate (ORR), PFS and overall survival (OS). Exploratory endpoints included association between response and tumor mutational burden (TMB), blood TMB, dynamic change of ctDNA and immune microenvironment.Results54 patients with advanced BTC were screened, of whom 38 eligible patients were enrolled. One patient withdrew informed consent before first dose treatment. Median follow-up was 11.8 months. The 6-month PFS rate was 50% (95% CI 33 to 65). Twenty (54%) out of 37 patients had an objective response. The median PFS was 6.1 months and median OS was 11.8 months. The most common treatment-related adverse events (TRAEs) were fatigue (27 (73%)) and fever (27 (73%)). The most frequent grade 3 or worse TRAEs were hypokalemia (7 (19%)) and fatigue (6 (16%)). The ORR was 80% in patients with programmed cell death ligand-1 (PD-L1) tumor proportion score (TPS) ≥1% versus 53.8% in PD-L1 TPS <1%. There was no association between response and TMB, blood TMB, immune proportion score or immune cells (p>0.05), except that PFS was associated with blood TMB. Patients with positive post-treatment ctDNA had shorter PFS (p=0.007; HR, 2.83; 95% CI 1.27 to 6.28).ConclusionCamrelizumab plus GEMOX showed a promising antitumor activity and acceptable safety profile as first-line treatment in advanced BTC patients. Potential biomarkers are needed to identify patients who might respond to camrelizumab plus GEMOX.Trial registration numberNCT03486678.

Project description:PurposeTH-302 is an investigational hypoxia-activated prodrug that releases the DNA alkylator bromo-isophosphoramide mustard in hypoxic settings. This phase II study (NCT01144455) evaluated gemcitabine plus TH-302 in patients with previously untreated, locally advanced or metastatic pancreatic cancer.Patients and methodsPatients were randomly assigned 1:1:1 to gemcitabine (1,000 mg/m(2)), gemcitabine plus TH-302 240 mg/m(2) (G+T240), or gemcitabine plus TH-302 340 mg/m(2) (G+T340). Randomized crossover after progression on gemcitabine was allowed. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), tumor response, CA 19-9 response, and safety.ResultsTwo hundred fourteen patients (77% with metastatic disease) were enrolled between June 2010 and July 2011. PFS was significantly longer with gemcitabine plus TH-302 (pooled combination arms) compared with gemcitabine alone (median PFS, 5.6 v 3.6 months, respectively; hazard ratio, 0.61; 95% CI, 0.43 to 0.87; P = .005; median PFS for metastatic disease, 5.1 v 3.4 months, respectively). Median PFS times for G+T240 and G+T340 were 5.6 and 6.0 months, respectively. Tumor response was 12%, 17%, and 26% in the gemcitabine, G+T240, and G+T340 arms, respectively (G+T340 v gemcitabine, P = .04). CA 19-9 decrease was greater with G+T340 versus gemcitabine (-5,398 v -549 U/mL, respectively; P = .008). Median OS times for gemcitabine, G+T240, and G+T340 were 6.9, 8.7, and 9.2 months, respectively (P = not significant). The most common adverse events (AEs) were fatigue, nausea, and peripheral edema (frequencies similar across arms). Skin and mucosal toxicities (2% grade 3) and myelosuppression (55% grade 3 or 4) were the most common TH-302-related AEs but were not associated with treatment discontinuation.ConclusionPFS, tumor response, and CA 19-9 response were significantly improved with G+TH-302. G+T340 is being investigated further in the phase III MAESTRO study (NCT01746979).
