MOUNTAINEER-03 phase III study design: first-line mFOLFOX6 + tucatinib + trastuzumab for HER2+ metastatic colorectal cancer.

Patients diagnosed with metastatic colorectal cancer (mCRC) have a poor prognosis with survival ranging 2-3 years. The prevalence of human epidermal growth factor receptor 2 (HER2) amplification is approximately 3-4% in mCRC and increases up to 8% in patients with // wild-type (WT) CRC tumors. Tucatinib is a highly selective HER2-directed tyrosine kinase inhibitor that, in combination with trastuzumab, has demonstrated clinically meaningful activity in patients with chemotherapy-refractory, HER2-positive (HER2+), WT mCRC in the MOUNTAINEER trial.

Final Analysis of Outcomes and RAS/BRAF Status in a Randomized Phase 3 Study of Panitumumab and Best Supportive Care in Chemorefractory Wild Type KRAS Metastatic Colorectal Cancer.

Introduction: Tumor rat sarcoma gene (RAS) status is a negative predictive biomarker for anti-epidermal growth factor receptor (EGFR) therapy in metastatic colorectal cancer (mCRC). We analyzed outcomes according to RAS and v-Raf murine sarcoma viral oncogene homolog B (BRAF) mutational status, and evaluated early tumor shrinkage (ETS) and depth of response (DpR) for patients with wild type RAS.

Patients And Methods: Patients with confirmed metastatic colon or rectum adenocarcinoma, wild type Kristen rat sarcoma gene tumor exon 2 status, clinical/radiologic disease progression or toxicity during irinotecan or oxaliplatin treatment, and no previous anti-EGFR therapy were randomized 1:1 to receive best supportive care (BSC) with or without panitumumab (6.

Exploratory pooled analysis evaluating the effect of sequence of biological therapies on overall survival in patients with wild-type metastatic colorectal carcinoma.

Background: The aim of this study was to evaluate the optimal sequence of targeted therapies (epidermal growth factor receptor inhibitors (EGFRi) and vascular endothelial growth factor inhibitors (VEGFi)), combined with chemotherapy, in patients with wild-type (WT) metastatic colorectal carcinoma (mCRC). Exploratory analyses of overall survival (OS) for patients treated with either first-line panitumumab (EGFRi) and second-line VEGFi therapy, or first-line bevacizumab (VEGFi) and second-line EGFRi, were conducted.

Methods: Patients from PEAK (NCT00819780), PRIME (NCT00364013) and Study 181 (NCT00339183), with WT or WT/ WT tumours, were included in the analyses.

Final analysis of the randomised PEAK trial: overall survival and tumour responses during first-line treatment with mFOLFOX6 plus either panitumumab or bevacizumab in patients with metastatic colorectal carcinoma.

Purpose: To report planned final overall (OS) and progression-free survival (PFS) analyses from the phase II PEAK trial (NCT00819780).

Methods: Patients with previously untreated, KRAS exon 2 wild-type (WT) metastatic colorectal cancer (mCRC) were randomised to mFOLFOX6 plus panitumumab or bevacizumab. The primary endpoint was PFS; secondary endpoints included OS, objective response rate, duration of response (DoR), time to response, resection and safety.

A phase 3 trial evaluating panitumumab plus best supportive care vs best supportive care in chemorefractory wild-type KRAS or RAS metastatic colorectal cancer.

Background: We assessed the treatment effect of panitumumab plus best supportive care (BSC) vs BSC on overall survival (OS) in patients with chemorefractory wild-type KRAS exon 2 metastatic colorectal cancer (mCRC) and report the first prospective extended RAS analysis in a phase 3 trial.

Methods: Patients with wild-type KRAS exon 2 mCRC were randomised 1 : 1 to panitumumab (6 mg kg Q2W) plus BSC or BSC. On-study crossover was prohibited.

Final results and outcomes by prior bevacizumab exposure, skin toxicity, and hypomagnesaemia from ASPECCT: randomized phase 3 non-inferiority study of panitumumab versus cetuximab in chemorefractory wild-type KRAS exon 2 metastatic colorectal cancer.

Purpose: The primary analysis of the ASPECCT study demonstrated that panitumumab was non-inferior to cetuximab for overall survival (OS) in patients with chemotherapy-refractory wild-type KRAS exon 2 metastatic colorectal cancer (mCRC). Here, we report the final analysis results of ASPECCT.

Patients And Methods: Patients with wild-type KRAS exon 2 mCRC who progressed on or were intolerant to irinotecan- or oxaliplatin-based chemotherapy were randomised to receive panitumumab 6 mg/kg once every 2 weeks or cetuximab (400 mg/m) followed by 250 mg/m weekly.

[IFTIR study on the micro-structure in the construction process of water-borne coatings].

Borne paint was studied in the article in which the solvent water was regarded as a variable factor. A series of paint samples with different percentage of water were configured before observing their storage performance and microstructures by using Fourier-transform infrared (FTIR) ATR (attenuated total reflection) spectroscopy and diffuse reflectance (DF) FTIR spectroscopy. The effects of construction process and solvent water on the coating film were examined through analyzing the changes of internal functional groups before and after coating.

Pharmacology and tolerability of a single dose of exenatide in adolescent patients with type 2 diabetes mellitus being treated with metformin: a randomized, placebo-controlled, single-blind, dose-escalation, crossover study.

Objective: This study assessed the pharmacokinetics, pharmacodynamics, and tolerability of single doses of exenatide in adolescent patients with type 2 diabetes mellitus (T2DM).

Methods: This was a randomized, single-blind, dose-escalation, crossover study in adolescent (age 10-16 years) patients with T2DM who were being treated with diet and exercise or a stable dose of metformin, a sulfonylurea, or a combination of metformin and a sulfonylurea for at least 3 months before screening. Eligible patients were allocated to receive single subcutaneous doses of exenatide 2.

Effects of exenatide versus sitagliptin on postprandial glucose, insulin and glucagon secretion, gastric emptying, and caloric intake: a randomized, cross-over study.

Background: This study evaluated the effects of exenatide, a GLP-1 receptor agonist, and sitagliptin, a DPP-4 inhibitor, on 2-h postprandial glucose (PPG), insulin and glucagon secretion, gastric emptying, and caloric intake in T2D patients.

Methods: This double-blind, randomized cross-over, multi-center study was conducted in metformin-treated T2D patients: 54% female; BMI: 33 +/- 5 kg/m(2); HbA(1c): 8.5 +/- 1.

Exenatide effects on diabetes, obesity, cardiovascular risk factors and hepatic biomarkers in patients with type 2 diabetes treated for at least 3 years.

Background: Exenatide, an incretin mimetic for adjunctive treatment of type 2 diabetes (T2DM), reduced hemoglobin A(1c) (A1C) and weight in clinical trials. The objective of this study was to evaluate the effects of > or = 3 years exenatide therapy on glycemic control, body weight, cardiometabolic markers, and safety.

Methods: Patients from three placebo-controlled trials and their open-label extensions were enrolled into one open-ended, open-label clinical trial.

The incretin mimetic exenatide as a monotherapy in patients with type 2 diabetes.

Background: Exenatide is an adjunctive therapy for type 2 diabetes, and preliminary evidence suggests that its glucoregulatory effects may be similar in the absence of oral therapy.

Methods: Study A was a randomized, double-blind, placebo-controlled study of 99 patients with type 2 diabetes that received either 10 microg twice-daily, 10 microg once-daily, or 20 microg once-daily exenatide or placebo for 28 days in the absence of background pharmacotherapy. Study B was an open-label extension of a short-term study of 127 patients with type 2 diabetes treated with metformin or diet and exercise.

Metabolic effects of two years of exenatide treatment on diabetes, obesity, and hepatic biomarkers in patients with type 2 diabetes: an interim analysis of data from the open-label, uncontrolled extension of three double-blind, placebo-controlled trials.

Background: Exenatide, an incretin mimetic for adjunctive treatment of type 2 diabetes mellitus (T2DM), reduced glycosylated hemoglobin (HbA(1c)) and weight in 30-week placebo-controlled trials. Some patients were followed up in open-label extensions to provide 'real-world' exenatide clinical experience.

Objective: The purpose of this study was to examine the metabolic effects of 2 years of exenatide treatment in patients with T2DM.
