Irinotecan (CPT-11) in combination with 5-fluorouracil (5FU) is widely used in the treatment of colorectal cancer. We assessed potential clinical variables that may predict toxicity and more specifically the role of UGT1A1 polymorphisms associated with irinotecan toxicity. We used data from the PETACC3 trial, which randomised patients in adjuvant setting to 6 months of leucovorin (LV) and 5FU (LV5/FU2) or LV5/FU2 + irinotecan.
Although irinotecan is an important anticancer drug for treating colorectal cancer, its dose-dependent side effects limited its clinical application. Thus, it's important to develop low-toxic candidates to enhance the efficacy of irinotecan. Polyynes from genus Oplopanax were reported to possess potential anticancer effects on colorectal cancer. Hereby, we evaluated the synergetic inhibition of human colorectal cancer cells by combining polyyne-enriched fraction from Oplopanax elatus (the dichloromethane fr...
The XELAVIRI trial investigated the optimal treatment strategy for patients with untreated metastatic colorectal cancer. We tested the noninferiority of initial treatment with a fluoropyrimidine plus bevacizumab, followed by the addition of irinotecan at first progression (arm A) versus upfront use of fluoropyrimidine plus irinotecan plus bevacizumab (arm B) in a 1:1 randomized, controlled phase III trial.
Because of the great interest for research on the potential use of cannabis preparations as co-medication for alleviation of toxic effects in cancer management, we investigated the influence of Δ-tetrahydrocannabinol (Δ-THC) to modulate irinotecan (CPT-11)-induced toxicity. Male Wistar rats were treated either with a single irinotecan intraperitoneal dose, 100 mg/kg body-weight (b.w.), or with irinotecan in combination with THC (7 mg/kg b. w., p. o., administered repeatedly for 1, 3 and 7 days). Seria...
Cholinergic syndrome is an acute adverse event frequently observed in patients administered irinotecan, and can sometimes negatively affect their quality of life. In some manifestations of the syndrome such as bradycardia, careful monitoring of patients is advised. In this study, we retrospectively investigated the risk factors associated with irinotecan-induced cholinergic syndrome in Japanese patients with cancer.
A novel PEG-cRGD-conjugated irinotecan derivative BGC0222 was designed and synthesized as antitumor agent. Antitumor activity screening assay indicated that BGC0222 exhibited better in vitro antiproliferation activity than irinotecan and NKTR-102 against HT29, MIA PaCa-2 and MCF-7 tumor cell lines, with IC of 1.83 ± 0.09 μM, 3.95 ± 0.16 μM and 0.68 ± 0.04 μM, respectively, while it displayed better in vivo antiproliferation activity than irinotecan and NKTR-102 in HT-29, MIA PaCa-2...
This study evaluated the effects of flavonoid-rich fraction from Bauhinia forficata leaves (FRF-BF), against intestinal toxicity induced by irinotecan. The leaves of this plant are used like tea in Brazilian folk medicine, and it is rich in flavonoids, mainly kaempferitrin. First, the chemopreventive effects of FRF-BF and kaempferitrin were evaluated in intestinal cells (IEC-6 cells) exposed to irinotecan. Next, the effects were evaluated against irinotecan-induced mucositis in mice. Lastly, melanoma was in...
Non-randomized studies showed that temozolomide (TMZ) achieves an average 10% response rate in heavily pretreated metastatic colorectal cancer (mCRC) patients with promoter methylation of the DNA repair gene O6-methylguanine-DNA methyltransferase (MGMT). In this phase II trial, irinotecan and temozolomide (TEMIRI) combination regimen was assessed in irinotecan-sensitive, MGMT methylated/microsatellite stable (MSS) pretreated mCRC patients.
Irinotecan is highly effective in the treatment of metastatic colorectal cancer as well as many other cancers. However, irinotecan is known to cause severe diarrhea, which pose significant problems in patients undergoing irinotecan based chemotherapy. Dietary and herbal components have shown promise in improving gastrointestinal health. Therefore, we compared the effect of grain-based chow diet containing phytoestrogens and corn/alfalfa as fat source to purified diets containing either animal-derived fat so...
Carboxylesterase and UDP-glucuronosyltransferases mediated metabolism of irinotecan: In vitro and in vivo insights from quantitative ultra-performance liquid chromatography-mass spectrometry analysis.
Carboxylesterase and UDP-glucuronosyltransferases mediated metabolism of irinotecan (CPT-11) has long been proposed to be responsible for its anti-tumor activity and toxicity, like delayed-onset diarrhea. However, recent studies failed to gain more comprehensive in vivo and in vitro pharmacokinetic profiles of irinotecan. Herein, we choose rat plasma, human liver microsomes and immortalized HepG2 cell as experimental subjects to describes an sensitive and versatile UHPLC-MS/MS method for simultaneously quan...
In this manuscript we aimed at the simultaneous separation and quantification of Gemcitabine and Irinotecan hydrochloride (injected both as single components and in combination) from Sprague Dawley rat plasma by using a validated method obtained through the use of a High Performance Liquid Chromatography (HPLC)-diode array detector (DAD). Gemcitabine and Irinotecan hydrochloride were detected and quantified using a Zorbax Extend C-18 column (250 mm × 4.6 mm; 5 μm particle size) in gradient eluti...
Evaluate the toxicity and efficacy of adjuvant temozolomide (TMZ) and irinotecan (CPT-11) for 12 months following concurrent chemo-radiation in newly diagnosed glioblastoma (GBM).
The implementation of therapeutic drug monitoring in the routine clinical practice in oncology is mainly limited by the lack of therapeutic indexes for the majority of the anticancer drugs, and by the absence of suitable analytical tools, which can accurately quantify in real time the concentration of the administered drugs and their relevant metabolites in biological fluids. In this work, a simple and efficient fluorimetric determination of SN-38, the active metabolite of the anticancer drug irinotecan, wa...
Lung cancer has become the most prevalent neoplasm throughout the world with 1,2 million deaths per year. Molecular genetic analyses have suggested that KRAS mutation is much more frequency in NSCLC. Significant challenges are to develop selective pharmacological inhibitors for RAS mutation to treat cancers driven. In our study, we used the combinatorial strategy to target oncogene addiction for RAS-mutant cells and the data showed that ABT199 and irinotecan leads to RAS-mutant lung cancer cell growth inhib...
To evaluate the safety and preliminary efficacy of dose-modified regimen of 5-fluorouracil plus oxaliplatin and irinotecan (mFOLFOXIRI) for patients with advanced colorectal cancer (CRC).
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. Cyclooxygenase-2 (COX-2) overexpression is associated with increased tumor invasiveness and proliferation in CRC, and COX-2 inhibition has demonstrated chemopreventive activity. This study investigated the addition of celecoxib, a selective COX-2 inhibitor, to the irinotecan, 5-fluorouracil, and leucovorin (IFL) regimen for patients with previously untreated metastatic CRC.
The NAPOLI-1 study (NCT01494506) reported that liposomal irinotecan plus 5-fluorouracil and leucovorin (nal-IRI+5-FU/LV) improved overall survival vs 5-FU/LV with manageable toxicity in patients with metastatic pancreatic adenocarcinoma previously treated with gemcitabine-based therapy. Yet, clinicians need treatment strategies that also maintain the patient's health-related quality of life (HRQOL). Here, we report the HRQOL data.
A combination of irinotecan/cisplatinum and irinotecan/temozolomide or tumor-targeting Salmonella typhimurium A1-R arrest doxorubicin- and temozolomide-resistant myxofibrosarcoma in a PDOX mouse model.
Myxofibrosarcoma (MFS) is the most common sarcomas in elderly patients and is either chemo-resistant or recurs with metastasis after chemotherapy. This recalcitrant cancer in need of improved treatment. We have established a patient-derived orthotopic xenograft (PDOX) of MFS. The MFS PDOX model was established in the biceps femoris of nude mice and randomized into 7 groups of 7 mice each: control; doxorubicin (DOX); pazopanib (PAZ); temozolomide (TEM); Irinotecan (IRN); IRN combined with TEM; IRN combined w...
Survival with nal-IRI (liposomal irinotecan) plus 5-fluorouracil and leucovorin versus 5-fluorouracil and leucovorin in per-protocol and non-per-protocol populations of NAPOLI-1: Expanded analysis of a global phase 3 trial.
In the phase 3 randomised NAPOLI-1 clinical study, a 45% increase in median overall survival (OS) was shown with liposomal irinotecan, 5-fluorouracil and leucovorin (nal-IRI+5-FU/LV) versus 5-FU/LV in patients with metastatic pancreatic cancer progressing after gemcitabine-based therapy. Here, we report data from a pre-specified, expanded analysis of outcomes in the per-protocol (PP) population.
Anti-proliferative, anti-metastatic and anti-angiogenic effects of 17‑allylamino‑17‑demethoxy geldanamycin (17-AAG) were studied alone and in combination with Capecitabine (Cap) and/or Irinotecan (IR) on HT-29 human colorectal carcinoma cells. Expression of MMP-9 (matrix metalloproteinase‑9) and VEGF (vascular endothelial growth factor) mRNA was analyzed by real-time PCR method. The study was further followed by wound scratch assay for migration assessment. Nitric oxide content, MDA generation and t...
Efficacy and safety of biweekly cetuximab plus irinotecan were evaluated to provide guidance for its use in Japan as third-line treatment for pretreated metastatic colorectal cancer patients harboring wild-type KRAS Exon 2. Objective response rate was used as primary endpoint based on an expected proportion of 0.23 with confidence width of 0.298 (95% confidence interval, 0.105-0.403), which showed 35 to be the minimal participant number. Forty patients, refractory to first- and second-line chemotherapy cont...
Nanomedicine based polymeric prodrug have showed high impact in the inhibition of tumor growth due to its high therapeutic efficiency and improved biocompatibility. Herein, we synthesized a novel star-like amphiphilic copolymer [β-CD-P(Ir-co-OEGMA), denoted as CPIO] through atom transfer radical polymerization (ATRP) to deliver the hydrophilic anticancer drug irinotecan (Ir). The polymer could form monodisperse unimolecular micelles and had excellent stability in aqueous solution. Moreover, the reduction-r...
Irinotecan (CPT-11) is used to treat various cancers but side effects such as delayed diarrhea restrict its use. Darunavir (DRV) is an antiretroviral drug used to treat and prevent human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), but whether DRV is protective against CPT-11-induced intestinal toxicity is unclear. An CPT-11-induced intestinal toxicity model was produced using uninterrupted CPT-11 (ip) for 4 d in mice. Enzyme-linked immuno sorbent assay (ELISA), fecal occult blood ...
