Project description:Real-World Effectiveness of Regorafenib in the Treatment of Patients with Metastatic Colorectal Cancer- A Retrospective, Observational Study
Project description:This is a multi-center, retrospective, real-world study. The purpose of this study is to observe the effectiveness and safety of regorafenib in Chinese advanced colorectal cancer patients.
The main observational goals include overall survival(OS), 6 month OS rate, 1 year OS rate, and treatment time failure (TTF), other study goals include objective response rate( ORR)、Disease control rate(DCR)and adverse event(AE) of regorafenib.
Project description:Prospective pharmacotyping of urothelial carcinoma organoids for drug sensitivity prediction – feasibility and real world experience
Project description:This prospective, multi-center, real-world study is conducted to investigate the impact of different treatment strategies (systemic chemotherapy combined with oophorectomy or with other local treatment or chemotherapy alone) on the prognosis of ovarian metastatic colorectal cancer patients.
Project description:Alzheimer’s disease (AD) is a chronic neurodegenerative disease needing effective therapeutics urgently. Sildenafil, one of the approved phosphodiesterase-5 inhibitors, has been implicated as having potential beneficial effect in AD. We showed that sildenafil usage is associated with reduced likelihood of AD across four new drug compactor cohorts, including bumetanide, furosemide, spironolactone, and nifedipine. For instance, sildenafil usage is associated with a 54% reduced prevalence of AD in MarketScan® (hazard ratio [HR] = 0.46, 95% CI 0.32-0.66) and a 30% reduced prevalence of AD in Clinformatics® (HR = 0.70, 95% CI 0.49-1.00) compared to spironolactone. We found that sildenafil treatment significantly reduced tau hyper-phosphorylation (pTau181, pTau205) in a dose-dependent manner in both familial and sporadic AD patient derived neurons. Further RNA-seq data analysis of sildenafil-treated AD patient iPSC-derived neurons revealed that sildenafil specifically targeting AD related genes and molecular pathways involved in axon guidance, AD-presenilin, neurogenesis, neurodegeneration, synaptic dysregulation, vascular smooth muscle contraction (VSMC) and cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) signaling pathway, mechanistically supporting the potential beneficial effect of sildenafil in AD. These real-world patient data validation and mechanistic observations from patient iPSC-derived neurons further suggested that sildenafil is a potential repurposable drug for AD. However, randomized clinical trials are required to validate sildenafil as a potential treatment of AD.
Project description:This is a phase IV multicenter trial to evaluate real-world health outcomes and economic impact of panitumumab versus standard-of-care (SOC) in the treatment of patients with chemotherapy-refractory metastatic colorectal cancer (mCRC).
The study will enable real-life health economics and outcome research (HEOR) to assess the impact of panitumumab in the Quebec population.
The primary objective is to evaluate real-world health outcomes and economic impact of panitumumab in the treatment of patients with chemotherapy-refractory mCRC in comparison with SOC. The secondary objectives are to confirm survival data, to assess the quality of life of patients and to assess the health care resource utilization of patients.
Patients with a mutated KRAS gene will be treated with standard-of-care (SOC) and patients with a non-mutated (wild type) KRAS gene will be treated with panitumumab.
During the course of the study, data will be collected on quality of life and work productivity. Patients will be asked to fill a set of questionnaires at their recruitment in the study and at every 3 months after treatment initiation.
Project description:Purpose: We evaluated clinical outcomes of patients with FGFR3-altered metastatic UC treated with ICB and investigate the underlying immunogenomic mechanisms of response and resistance Methods: 103 patients with metastatic UC treated with ICB at a single academic medical center from 2014-2018 were identified. Clinical annotation for demographics and cancer outcomes, as well as somatic DNA and RNA sequencing were performed. Objective response rate to ICB, progression-free survival, and overall survival was compared between patients with FGFR3 alterations and those without. RNA expression, including molecular subtyping and T cell receptor clonality, was also compared between FGFR3-altered and non-altered patients Results: Our findings from this dataset confirm that FGFR3-altered (n=17) and wild type (n=86) bladder cancers are equally responsive to ICB (12 vs 19%, p=0.73). Moreover, we demonstrate that despite being less inflamed, FGFR3-altered tumors have equivalent T cell receptor (TCR) diversity and that the balance of a CD8 T cell gene expression signature to immune suppressive features is an important determinant of ICB response Conclusions: Our work in a real world dataset validates prior observations from clinical trials but also extends this prior work to demonstrate that FGFR3-altered and wild type tumors have equivalent TCR diversity and that the balance of effector T cell to immune suppression signals are an important determinant of ICB response.
Project description:This is a single-arm, open label, multinational, multicentre, prospective, real world observational study of Naloxegol in adult subjects with Opioid Induced Constipation (OIC) in patients receiving Naloxegol in routine clinical practice. Subjects who are receiving Naloxegol (prescribed by their physician according to the SmPC, which recommends that all currently used maintenance laxative therapy should be halted) during the enrolment period may be eligible for enrolment into the study.
