Afinitor

In this study, novel morpholinopyrimidine-5-carbonitriles were designed and synthesized as dual PI3K/mTOR inhibitors and apoptosis inducers. The integration of a heterocycle at position 2, with or without spacers, of the new key intermediate 2-hydrazinyl-6-morpholinopyrimidine-5-carbonitrile (5) yielded compounds 6-10, 11a-c and 12a-h. The National Cancer Institute (USA) tested all compounds for antiproliferative activity. Schiff bases, 12a-h analogs, were the most active ones. The most promising compounds 12b and 12d exhibited excellent antitumor activity against the leukemia SR cell line, which is the most sensitive cell line, with IC50 0...

Background: Everolimus is an inhibitor of mammalian target of rapamycin complex 1. As mutations in TSC1 and TSC2 , which cause partial-onset seizures associated with TSC, were found in focal cortical dysplasia type Ⅱ (FCD Ⅱ) patients, a clinical trial has been performed to explore the efficacy and safety of everolimus in FCD patients. However, no dosage regimen was determined to treat FCD II. To recommend an optimal dose regimen for FCD patients, a population pharmacokinetic model of everolimus in FCD patients was developed...

Cancer treatments such as chemotherapies may change or accelerate aging trajectories in cancer patients. Emerging evidence has shown that "omics" data can be used to study molecular changes of the aging process. Here, we integrated the drug-induced and normal aging transcriptomic data to computationally characterize the potential cancer drug-induced aging process in patients. Our analyses demonstrated that the aging-associated gene expression in the GTEx dataset can recapitulate the well-established aging hallmarks...

BACKGROUND: Despite endocrine therapy being the mainstay of treatment for hormone receptor positive (HR+)/HER2- metastatic breast cancer, patients at risk of visceral crisis or doubt for endocrine sensitivity are still offered first-line chemotherapy. Maintenance hormonal therapy is generally offered at the discontinuation of chemotherapy. The MAINtenance Afinitor study is a randomised, phase III trial comparing maintenance everolimus combined with aromatase inhibitors (AIs) versus AI monotherapy in patients with disease control after first-line chemotherapy...

BACKGROUND: Renal cell carcinoma (RCC) is the most common type of kidney cancer, and accounts for approximately 3% of all malignancies. Metastatic RCC (mRCC) is not sensitive to traditional radiotherapy and chemotherapy, therefore targeted therapy has become an important treatment option. In this study, the second-line targeted drug everolimus (Afinitor), a mammalian target of rapamycin (mTOR) inhibitor, was investigated for its clinical efficacy and adverse events in mRCC after failure of first-line targeted therapy, such as sorafenib, sunitinib or pazopanib...

Everolimus (Afinitor) is an inhibitor of mammalian target of rapamycin. Polmacoxib (Acelex) is a nonsteroidal anti-inflammatory drug that belongs to the cyclooxygenase-2 (COX-2) inhibitor family and is mainly used for treatment of arthritis. Intestinal perforation has not been reported previously as a complication of everolimus, and perforation of the lower intestinal tract caused by a selective COX2 inhibitor is extremely rare. We present here a case of colon perforation that occurred after use of polmacoxib in a metastatic breast cancer patient who had been treated with everolimus for the preceding six months...

BACKGROUND: Neuroendocrine tumours (NETs) are a group of heterogeneous cancers that develop in cells in the diffuse neuroendocrine system. OBJECTIVES: To estimate the clinical effectiveness of three interventions [everolimus (Afinitor® ; Novartis International AG, Basel, Switzerland), lutetium-177 DOTATATE (177Lu-DOTATATE) (Lutathera® ; Imaging Equipment Ltd, Radstock, UK) and sunitinib (Sutent® ; Pfizer Inc., New York, NY, USA)] for treating unresectable or metastatic NETs with disease progression and establish the cost-effectiveness of these interventions...

Everolimus (RAD001) is an oral protein kinase inhibitor of the mTOR (mammalian target of rapamycin) serine/threonine kinase signal transduction pathway. The mTOR pathway regulates cell growth, proliferation and survival, and is frequently deregulated in cancer.The EMA has approved Everolimus as Afinitor® for the treatment of hormone receptor-positive, HER2/neu-negative advanced breast cancer, in combination with exemestane, in postmenopausal women without symptomatic visceral disease after recurrence or progression following a nonsteroidal aromatase inhibitor, for the treatment of unresectable or metastatic, well- or moderately differentiated neuroendocrine tumors of pancreatic origin in adults with progressive disease, and for the treatment of unresectable or metastatic, well-differentiated (Grade 1 or Grade 2) nonfunctional neuroendocrine tumors of gastrointestinal or lung origin in adults with progressive disease, and for the treatment of patients with advanced renal cell carcinoma, whose disease has progressed on or after treatment with VEGF-targeted therapy And as Votubia® for the treatment of adult patients with renal angiomyolipoma associated with tuberous sclerosis complex (TSC), who are at risk of complications (based on factors such as tumor size or presence of aneurysm, or presence of multiple or bilateral tumors) but who do not require immediate surgery, and for the treatment of patients with subependymal giant cell astrocytoma (SEGA) associated with TSC who require therapeutic intervention but are not amenable to surgery, and as an add-on treatment in patients from 2 years of age with seizures related to TSC that have not responded to other treatments ( https://www...

Infection with the larval stage (metacestode) of the fox tapeworm Echinococcus multilocularis leads to a primary hepatic disease referred to as alveolar echinococcosis (AE). The progressive disease can be lethal if untreated. In cases where complete parasite resection by surgery is not feasible, the current treatment regimens of AE consist of chemotherapy with the parasitostatic benzimidazoles albendazole or mebendazole over decades. Kinase-inhibitors currently administered in various cancer treatments are of increasing interest also as anti-parasitic drugs due to previous promising in vitro results...

BACKGROUND: Several therapies have recently been approved for use in the NHS for pretreated advanced or metastatic renal cell carcinoma (amRCC), but there is a lack of comparative evidence to guide decisions between them. OBJECTIVE: To evaluate the clinical effectiveness and cost-effectiveness of axitinib (Inlyta® , Pfizer Inc., NY, USA), cabozantinib (Cabometyx® , Ipsen, Slough, UK), everolimus (Afinitor® , Novartis, Basel, Switzerland), nivolumab (Opdivo® , Bristol-Myers Squibb, NY, USA), sunitinib (Sutent® , Pfizer, Inc...

INTRODUCTION: Pancreas, parathyroid, and pituitary, are referred to as the "3 Ps" of MEN1. The time has come to move beyond those Ps and begin to discuss (1) prediction, (2) pausing progression, and (3) prevention of MEN1. METHODS: In preparation for the International Association of Endocrine Surgeons State of the Art address, updates and uncertainties of MEN were reviewed. This included a detailed examination of the MEN1 gene and the library of implicated mutations, exon sequencing databases and cell cycle pathways...

OBJECTIVE: The aim of this study was to report cases of medication-related osteonecrosis of the jaws (MRONJ) associated with targeted therapy (TT) with or without concomitant antiresorptive treatment, among the Copenhagen ONJ cohort, which includes all consecutive cases of MRONJ seen in Copenhagen. STUDY DESIGN: We retrospectively studied the treatment of 204 consecutive patients with MRONJ, seen between January 2010 and May 2016, to identify those associated with TT...

BACKGROUND Von Hippel-Lindau (VHL) disease is a rare autosomal dominant syndrome manifested by a spectrum of benign and malignant tumors.  CASE REPORT The patient presented here was a 31-year-old female with unremarkable family history who presented initially complaining of intermittent abdominal pain. Abdominal CT scan revealed an inhomogeneous solid mass (13×9×7 cm) originating from the tail of the pancreas with splenic and gastric invasion as well as several pancreatic cysts. A nucleotide scan showed left adrenal involvement...

We report on a 27 years old female patient who was referred to our department for whole-body as well as dynamic positron emission tomography/computed tomography (dPET/CT) scan of the upper and middle abdomen with fluorine-18-fluorodeoxy glucose (18 F-FDG), for further evaluation of a mass in the left adrenal gland region. Positron emission tomography showed a suspicious, enlarged, hypermetabolic mass with an average standardized uptake value (SUV) of 4.5 and a maximum SUV of 5.9. The patient was referred for biopsy, which revealed an angiomyolipoma, a perivascular epithelioid cell tumor (PEComa) of the adrenal gland...

The mTOR pathway was discovered in the late 1970s after the compound and natural inhibitor of mTOR, rapamycin was isolated from the bacterium Streptomyces hygroscopicus. mTOR is serine/threonine kinase belonging to the phosphoinositide 3-kinase related kinase (PIKK) family. It forms two distinct complexes; mTORC1 and mTORC2. mTORC1 has a key role in regulating protein synthesis and autophagy whilst mTORC2 is involved in regulating kinases of the AGC family. mTOR signaling is often over active in multiple cancer types including breast cancer...

A 60-year-old man initially presented with pain in the right upper quadrant in October 2010. A computed tomography (CT) scan of the abdomen pelvis completed at that time showed a mass at the junction of the body and tail of the pancreas and multiple large liver lesions. A CT-guided liver biopsy revealed low-grade neuroendocrine carcinoma. The patient was initially started on systemic treatment with sunitinib (Sutent) and octreotide. He developed intolerable side effects, including nausea and migraine. Therapy was discontinued in October 2011, when a CT scan revealed evidence of disease progression...

BACKGROUND: mTOR inhibition of aromatase inhibitor (AI)-resistant breast cancer is currently under evaluation in the clinic. Everolimus/RAD001 (Afinitor®) has had limited efficacy as a solo agent but is projected to become part of combination therapy for AI-resistant breast cancer. This study was conducted to investigate the anti-proliferative and resistance mechanisms of everolimus in AI-resistant breast cancer cells. METHODS: In this study we utilized two AI-resistant breast cancer cell lines, MCF-7:5C and MCF-7:2A, which were clonally derived from estrogen receptor positive (ER+) MCF-7 breast cancer cells following long-term estrogen deprivation...

BACKGROUND: Real-world data of everolimus after vascular endothelial growth factor receptor (VEGFR)-tyrosine kinase inhibitor (TKI) therapy in metastatic renal cell carcinoma (mRCC) are limited. PATIENTS AND METHODS: The retrospective, noninterventional SECTOR (SECond line with afiniTOR) study (N = 165) assessed outcomes of second-line everolimus after initial VEGFR-TKI (TKI-everolimus, n = 144) and of third-line VEGFR-TKI after everolimus (TKI-everolimus-TKI, n = 59) in patients with mRCC...

We analyzed the dynamics of the expression of transcription factors, VEGF and its receptor VEGFR2, serine-threonine protein kinase mTOR and activity of proteasome and calpain in patients with metastatic renal cancer during therapy with tyrosine kinase inhibitor Votrient and mTOR blocker Afinitor. The expression of hypoxic nuclear factor HIF-1α in the tumor tissue decreased during therapy with the target preparations. The decrease of VEGF and its receptor VEGFR2 was observed only in patients treated with mTOR inhibitor...

The mTORC1 inhibitor everolimus (Afinitor/RAD001) has been approved for multiple cancer indications, including ER(+)/HER2(-) metastatic breast cancer. However, the combination of everolimus with the dual PI3K/mTOR inhibitor BEZ235 was shown to be more efficacious than either everolimus or BEZ235 alone in preclinical models. Herein, we describe a male breast cancer (MBC) patient who was diagnosed with hormone receptor-positive (HR(+))/HER2(-) stage IIIA invasive ductal carcinoma and sequentially treated with chemoradiotherapy and hormonal therapy...
