triple therapy

(no author information available yet)
Findings from a phase I/II study indicate a higher response rate among patients with BRAF-mutant metastatic colorectal cancer treated with an EGFR inhibitor alongside dual, as opposed to single-level, MAPK blockade. Panitumumab combined with trametinib and dabrafenib only modestly increased median progression-free survival, however; a short-lived decrease in responders' BRAF V600E mutant allele fraction and the emergence of RAS mutations may have been contributing factors.

CLN3 disease (Spielmeyer-Vogt-Sjogren-Batten disease, previously known as classic juvenile neuronal ceroid lipofuscinosis, NCL) is a pediatric-onset progressive neurodegenerative disease characterized by progressive vision loss, seizures, loss of cognitive and motor function, and early death. While no precise biochemical mechanism or therapies are known, the pathogenesis of CLN3 disease involves intracellular calcium accumulation that may trigger apoptosis. Our prior work in in vitro cell models of CLN3 deficiency suggested that FDA-approved calcium channel antagonists may have therapeutic value...

Triple-negative breast cancer (TNBC), which accounts for 15-20% of all breast cancers, does not express estrogen receptor (ER) or progesterone receptor (PR) and lacks human epidermal growth factor receptor 2 (HER2) overexpression or amplification. These tumors have a more aggressive phenotype and a poorer prognosis due to the high propensity for metastatic progression and absence of specific targeted treatments. Patients with TNBC do not benefit from hormonal or trastuzumab-based targeted therapies because of the loss of target receptors...

Dear Editor, We have read with great interest the recent published manuscript by Caiazza et al. (2016), which provides novel exciting findings about the potential therapeutic value of enzalutamide in patients with androgen receptor (AR)-positive triple negative breast cancer (TNBC). Some previous studies have shown promising antitumor effects of this drug in breast tumors. Thus, enzalutamide-mediated AR inhibition has been reported to reduce proliferation, anchorage-independent growth, migration, and invasion and increases apoptosis of TNBC cells in vitro and decrease viability of TNBC xenografts in vivo (Cochrane et al...

BACKGROUND: Mammalian target of rapamycin (mTOR) represents a key downstream intermediate for a myriad of oncogenic receptor tyrosine kinases. In the case of the insulin-like growth factor (IGF) pathway, the mTOR complex (mTORC1) mediates IGF-1 receptor (IGF-1R)-induced estrogen receptor alpha (ERα) phosphorylation/activation and leads to increased proliferation and growth in breast cancer cells. As a result, the prevalence of mTOR inhibitors combined with hormonal therapy has increased in recent years...

Purpose: In a recent meta-analysis, post-mastectomy radiotherapy (PMRT) reduced any first recurrence (AFR) and improved survival in N1 and N2 patients. We investigated risk factors for AFR in N1 after optimal systemic therapy without PMRT, to define a subgroup of patients who may benefit from PMRT. Materials and Methods: 1,382 pT1-2N1M0 breast cancer patients treated with mastectomy without PMRT between 2005 and 2010 were retrospectively analyzed. Only 0.6% had no systemic therapy...

BACKGROUND AND AIM: The number of patients with type 2 diabetes (T2DM) is increasing. Most patients with T2DM are uncontrolled and fail to achieve their target Hba1c. In recent years, newer agents such as SGLT2 inhibitors (SGLT2i) have been approved for clinical use. Though data from clinical trials and sub set analysis of Indian patients in global studies are promising, real world evidence from standard clinical practice in India is lacking. The aim of this study was to analyze the metabolic parameters in patients with T2DM on SGLT2i in real world clinical practice...

Stimuli-responsive nanocarriers with the ability to respond to tumorous heterogeneity have been extensively developed for drug delivery. However, the premature release during blood circulation and insufficient intracellular drug release are still a significant issue. Herein, three disulfide bonds are introduced into the amphiphilic poly(ethylene glycol)-polycaprolactone copolymer blocks to form triple-sensitive cleavable polymeric nanocarrier (tri-PESC NPs) to improve its sensitivity to narrow glutathione (GSH) concentration...

We compared the efficacy of activity monitor (which displays exercise intensity and number of steps) versus that of pedometer in exercise therapy for patients with type 2 diabetes. The study subjects were divided into the activity monitor group (n = 92) and pedometer group (n = 95). The primary goal was improvement in hemoglobin A1c (HbA1c). The exercise target was set at 8,000 steps/day and 20 minutes of moderate-intensity exercise (≥3.5 metabolic equivalents). The activity monitor is equipped with a triple-axis accelerometer sensor capable of measuring medium-intensity walking duration, number of steps, walking distance, calorie consumption, and total calorie consumption...

Our previous phase II clinical trial showed that therapeutically selected personalized peptide vaccines(PPVs)were effective at boosting anticancer immunity; the immune response after PPV was associated with a clinical outcome as a prognostic factor for metastatic breast cancer(mBC). We conducted an early phase II study to evaluate the safety and efficacy of a new regimen using multiple peptide vaccines(KRM-19)for patients with metastatictriple -negative breast cancer. KRM-19 consisted of 19 mixed peptides chosen from the previously reported 31 PPVs according to their anti-tumor immunologiceffec ts and safety profiles for patients with mBC...

Following the discovery that the prognostic impact of preoperative chemotherapy depends on the primary breast cancer subtype, the treatment strategy for primary breast cancer changed. Pathologic complete response(pCR)with preoperative chemotherapy is predictive of a favorable prognosis in patients with HER2 type or triple-negative type breast cancer, but not in patients with ER-positive/HER2-negative, the so-called Luminal type, breast cancer. However, the role of preoperative chemotherapy in patients with Luminal-B type breast cancer who may need chemotherapy should be further assessed...

The development of inhibitory antibodies to therapeutic FVIII is the major complication of replacement therapy in patients with hemophilia A. The first step in the initiation of the anti-FVIII immune response is FVIII interaction with receptor(s) on antigen-presenting cells followed by endocytosis and presentation to naive CD4+ T cells. Recent studies indicate a role for the C1 domain in FVIII uptake. We investigated whether charged residues in the C2 domain participate in immunogenic FVIII uptake. Co-incubation of FVIII with BO2C11, a monoclonal C2-specific IgG, reduced FVIII endocytosis by dendritic cells and presentation to CD4+ T cells, and diminished FVIII immunogenicity in FVIII-deficient mice...
