Background: Rolapitant, a long-acting neurokinin (NK) 1 receptor antagonist (RA), has demonstrated efficacy in prevention of chemotherapy-induced nausea and vomiting in patients administered moderately or highly emetogenic chemotherapy. Unlike other NK 1 RAs, rolapitant does not inhibit or induce cytochrome P450 (CYP) 3A4, but it does inhibit CYP2D6 and breast cancer resistance protein (BCRP). To analyze potential drug-drug interactions between rolapitant and concomitant medications, this integrated safety analysis of four double-blind, randomized phase II or III studies of rolapitant examined adverse events by use versus non-use of drug substrates of CYP2D6 or BCRP...

AIM: Glucagon-like peptide-1 (GLP-1) receptor agonists are a kind of very popular antidiabetes drugs. They promote cell proliferation and survival through activation of signaling pathways in human islet cells involving phosphate idylinositol 3 kinase (PI3K) and extracellular regulated kinases 1 and 2 (ERK1/2), which are frequently activated in human colon cancer cells. Then, it is possible that taking GLP-1 receptor (GLP-1R) agonists persistently would induce proliferation of β cells as well as colon cancer cells...

PURPOSE: Half-life of SN-38, an active metabolite of irinotecan, remarkably increases in patients with end-stage kidney disease (ESKD), even though SN-38 is excreted in bile. Uremic toxins (UTs), which accumulate in the serum of ESKD patients, were reported to inhibit organic anion-transporting polypeptide (OATP) 1B1-mediated uptake of SN-38; however, the relevance of this finding in a clinical setting is unknown. This study focused on cooperative effects of serum components and UTs on OATP1B1-mediated transport of SN-38...

PURPOSE: In recent years, significant progress in survival has been achieved using systemic combination chemotherapy in patients with pancreatic cancer. However, the elderly are largely underrepresented in clinical trials, and gains made from these may not necessarily apply to this important subgroup of patients. We review the currently available data regarding contemporary combination chemotherapy regimens, including FOLFIRINOX, gemcitabine plus nab-paclitaxel, nanoliposomal irinotecan plus 5-fluorouracil and leucovorin, and gemcitabine plus capecitabine, in elderly pancreatic cancer patients...

The prognosis of metastatic pancreatic adenocarcinoma has recently begun to improve. In the last several years, first-line therapy with gemcitabine plus nab-paclitaxel or a regimen of fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) has boosted the median overall survival (OS) duration to 8.5 months and 11 months, respectively, in patients with metastatic pancreatic cancer, compared with a historic OS of only 6 months prior to 2011. Moreover, sequencing these two regimens improved median OS to an unprecedented 18 months...

Purpose Trop-2, expressed in most triple-negative breast cancers (TNBCs), may be a potential target for antibody-drug conjugates. Sacituzumab govitecan, an antibody-drug conjugate, targets Trop-2 for the selective delivery of SN-38, the active metabolite of irinotecan. Patients and Methods We evaluated sacituzumab govitecan in a single-arm, multicenter trial in patients with relapsed/refractory metastatic TNBC who received a 10 mg/kg starting dose on days 1 and 8 of 21-day repeated cycles. The primary end points were safety and objective response rate; secondary end points were progression-free survival and overall survival...

Irinotecan, (CPT-11), an antitumor agent primarily used for the treatment of solid tumors, has often compromised clinical application due to the inducement of severe delay-onset diarrhea. Bile acid malabsorption (BAM) is widely accepted as the common cause of diarrhea. However, whether CPT-11-induced diarrhea has correlation with BAM is unknown. The aim of this study was to investigate the effect of CPT-11 on the bile acid homeostasis in mice. The mice were administrated with CPT-11 intravenously for four consecutive days...

Intramuscularly administered, anti-tumour drugs induce severe side effects due to their direct contact with body tissues and initial burst effect. In this study, to solve this problem, a novel double-reversible thermogel system (DRTG) for the intramuscular administration of irinotecan was developed. This irinotecan-loaded DRTG was prepared by dispersing the irinotecan-loaded thermoreversible solid lipid nanoparticles (SLNs) in the thermoreversible hydrogel. In DRTG, the former was solid at 25°C but converted to liquid at 36...

BACKGROUND: Chemotherapy-related liver injury (CALI) increase the risk of liver resection and may prejudice further surgery and chemotherapy. CALI's reversibility is thus relevant; however, no data concerning this are available. We therefore retrospectively analyzed the reversibility of CALI in patients undergoing liver resection for colorectal metastases. METHODS: All resections of colorectal liver metastases after oxaliplatin and/or irinotecan-based chemotherapy were included...

BACKGROUND: In the management of metastatic colorectal cancer (mCRC), KRAS, NRAS and BRAF mutational status individualizes therapeutic options and identify a cohort of patients (pts) with an aggressive clinical course. We hypothesized that relapsed and refractory mCRC pts develop unique mutational signatures that may guide therapy, predict for a response and highlight key signaling pathways important for clinical decision making. METHODS: Relapsed and refractory mCRC pts (N=32) were molecularly profiled utilizing commercially available next generation sequencing (NGS) platforms...

Masashi Takano, Toru Sugiyama
Mutations in the UGT1A1 gene have been implicated in Gilbert syndrome, which shows mild hyperbilirubinemia, and a more aggressive childhood subtype, Crigler-Najjar syndrome. To date, more than 100 variants have been found in the UGT1A1 gene. Among them, UGT1A1*28 and UGT1A1*6 have been reported to be associated with severe toxicities in patients treated with irinotecan-based chemotherapy by increasing the dose of SN-38 (7-ethyl-10-hydroxycamptothecin), an active form of irinotecan. Many association studies and meta-analyses have demonstrated the contribution of UGT1A1*28 and UGT1A1*6 polymorphisms to the toxicities caused by irinotecan-based therapy...

The binding of irinotecan, a potent anti cancer drug, to bovine beta-lactoglobulin (β-LG) was investigated by various spectroscopic techniques including fluorimetry, circular dichroism (CD), UV-vis, and Fourier transform infrared (FT-IR), in 10mM phosphate buffer, pH 7.75, in combination with a molecular docking study. Analysis of the fluorescence quenching data showed that combined static and dynamic quenching occurs, with the predominant contribution of the static mode. Molecular docking results were in full agreement with the results obtained from thermodynamic analysis of the fluorescence data indicating the existence of one binding site for irinotecan in β-LG structure and revealed the hydrophobic nature of the interaction between irinotecan and the protein...
