TL;DR: A potent, orally active small-molecule inhibitor of CDK4/6 that is active in xenograft tumors and may be used alone or in combination with standard-of-care cytotoxic therapy is identified.
Abstract: The G1 restriction point is critical for regulating the cell cycle and is controlled by the Rb pathway (CDK4/6-cyclin D1-Rb-p16/ink4a). This pathway is important because of its inactivation in a majority of human tumors. Transition through the restriction point requires phosphorylation of retinoblastoma protein (Rb) by CDK4/6, which are highly validated cancer drug targets. We present the identification and characterization of a potent CDK4/6 inhibitor, LY2835219. LY2835219 inhibits CDK4 and CDK6 with low nanomolar potency, inhibits Rb phosphorylation resulting in a G1 arrest and inhibition of proliferation, and its activity is specific for Rb-proficient cells. In vivo target inhibition studies show LY2835219 is a potent inhibitor of Rb phosphorylation, induces a complete cell cycle arrest and suppresses expression of several Rb-E2F-regulated proteins 24 hours after a single dose. Oral administration of LY2835219 inhibits tumor growth in human tumor xenografts representing different histologies in tumor-bearing mice. LY2835219 is effective and well tolerated when administered up to 56 days in immunodeficient mice without significant loss of body weight or tumor outgrowth. In calu-6 xenografts, LY2835219 in combination with gemcitabine enhanced in vivo antitumor activity without a G1 cell cycle arrest, but was associated with a reduction of ribonucleotide reductase expression. These results suggest LY2835219 may be used alone or in combination with standard-of-care cytotoxic therapy. In summary, we have identified a potent, orally active small-molecule inhibitor of CDK4/6 that is active in xenograft tumors. LY2835219 is currently in clinical development.

TL;DR: It is argued that some simple but commonly used methods to handle incomplete longitudinal clinical trial data require restrictive assumptions and stand on a weaker theoretical foundation than likelihood-based methods developed under the missing at random (MAR) framework, and their optimal place is within sensitivity analysis.
Abstract: Using standard missing data taxonomy, due to Rubin and co-workers, and simple algebraic derivations, it is argued that some simple but commonly used methods to handle incomplete longitudinal clinical trial data, such as complete case analyses and methods based on last observation carried forward, require restrictive assumptions and stand on a weaker theoretical foundation than likelihood-based methods developed under the missing at random (MAR) framework. Given the availability of flexible software for analyzing longitudinal sequences of unequal length, implementation of likelihood-based MAR analyses is not limited by computational considerations. While such analyses are valid under the comparatively weak assumption of MAR, the possibility of data missing not at random (MNAR) is difficult to rule out. It is argued, however, that MNAR analyses are, themselves, surrounded with problems and therefore, rather than ignoring MNAR analyses altogether or blindly shifting to them, their optimal place is within sensitivity analysis. The concepts developed here are illustrated using data from three clinical trials, where it is shown that the analysis method may have an impact on the conclusions of the study.

TL;DR: As the burden of illness associated with hip fracture extends beyond the initial hospitalization, a longitudinal 1 year cohort study was used to analyze levels of health service use, institutional care and their associated costs, and to examine patient and residency factors contributing to overall 1 year cost.
Abstract: As the burden of illness associated with hip fracture extends beyond the initial hospitalization, a longitudinal 1 year cohort study was used to analyze levels of health service use, institutional care and their associated costs, and to examine patient and residency factors contributing to overall 1 year cost. Patients in the study were aged 50 year and over, and had been admitted to an acute care facility for hip fracture in the Hamilton–Wentworth region of Canada from 1 April 1995 to 31 March 1996. Health care resources assessed included initial hospitalization, rehospitalization, rehabilitation, chronic care, home care, long-term care (LTC) and informal care. Regression analysis was used to determine the effects of age, gender, residence, survival and days of follow-up on 1 year cost. The mean 1 year cost of hip fracture for the 504 study patients was 26.527 Canadian dollars (95% Cl: $24.564–$28.490). One year costs were significantly different for patients who returned to the community ($21.385), versus those who were transferred to ($44.156), or readmitted to LTC facilities ($33.729) (p<0.001). Initial hospitalization represented 58% of 1 year cost for community-dwelling patients, compared with 27% for LTC residents. Only 59.4% of community-dwelling patients resided in the community 1 year following hip fracture, and 5.6% of patients who survived their first fracture experienced a subsequent hip fracture. Linear regression indicated place of residence, age and survival were all important contributors to 1 year cost (p<0.001). While the average 1 year cost of care was $26.527, the overall cost varied depending on a patient”s place of residence, age, and survival to 1 year. Annual economic implications of hip fracture in Canada are $650 million and are expected to rise to $2.4 billion by 2041.

TL;DR: It is demonstrated here that airway macrophages had higher expression of the negative regulator CD200 receptor (CD200R) than did their systemic counterparts and were restrained by CD200 expressed on airway epithelium, which limits inflammatory amplitude and duration during pulmonary influenza infection.
Abstract: The lung must maintain a high threshold of immune 'ignorance' to innocuous antigens to avoid inflammatory disease that depends on the balance of positive inflammatory signals and repressor pathways We demonstrate here that airway macrophages had higher expression of the negative regulator CD200 receptor (CD200R) than did their systemic counterparts Lung macrophages were restrained by CD200 expressed on airway epithelium Mice lacking CD200 had more macrophage activity and enhanced sensitivity to influenza infection, which led to delayed resolution of inflammation and, ultimately, death The administration of agonists that bind CD200R, however, prevented inflammatory lung disease Thus, CD200R is critical for lung macrophage immune homeostasis in the resting state and limits inflammatory amplitude and duration during pulmonary influenza infection

TL;DR: Exenatide, an incretin mimetic for the adjunct treatment of type 2 diabetes (DM2), reduced A1C and weight in 30‐week placebo‐controlled trials in patients unable to achieve adequate glycaemic control with sulphonylurea and/or metformin.
Abstract: Aim: Exenatide, an incretin mimetic for the adjunct treatment of type 2 diabetes (DM2), reduced A1C and weight in 30-week placebo-controlled trials. This analysis examined the effects of exenatide on glycaemic control and weight over an 82-week period in patients with DM2 unable to achieve adequate glycaemic control with sulphonylurea (SU) and/or metformin (MET).
Methods: This interim analysis is of 314 patients who received exenatide in the 30-week placebo-controlled trials and subsequently in 52 weeks of open-label uncontrolled extension studies for 82 weeks of exenatide in total. Patients continued their SU and/or MET regimens throughout.
Results: Patients completed 82 weeks of exenatide treatment [n = 314, 63% M, age 56 ± 10 years, weight 99 ± 21 kg, body mass index 34 ± 6 kg/m2, A1C 8.3 ± 1.0% (mean ± SD)]. Reduction in A1C from baseline to week 30 [−0.9 ± 0.1% (mean ± SE)] was sustained to week 82 (−1.1 ± 0.1%), with 48% of patients achieving A1C ≤ 7% at week 82. At week 30, exenatide reduced body weight (a secondary endpoint) from baseline (−2.1 ± 0.2 kg), with progressive reduction at week 82 (−4.4 ± 0.3 kg). Similar results were observed for the intent-to-treat population (n = 551), with reductions in A1C and weight at week 82 of −0.8 ± 0.1% and −3.5 ± 0.2 kg respectively. The 82-week completer cohort showed statistically significant improvement in some cardiovascular risk factors. The most frequent adverse events were generally mild-to-moderate nausea and hypoglycaemia.
Conclusion: In summary, 82 weeks of adjunctive exenatide treatment in patients with DM2 treated with SU and/or MET resulted in sustained reduction in A1C and progressive reduction in weight, as well as improvement in some cardiovascular risk factors.
