- Abstract
Background: In the phase III CheckMate 743 study (NCT02899299), first-line nivolumab plus ipilimumab significantly improved overall survival (OS) versus chemotherapy in patients with unresectable malignant pleural mesothelioma (MPM). We report updated data with 3-year minimum follow-up. Patients and methods: Adults with previously untreated, histologically confirmed, unresectable MPM and Eastern Cooperative Oncology Group performance status of ≤1 were randomized 1: 1 to nivolumab (3 mg/kg every 2 weeks) plus ipilimumab (1 mg/kg every 6 weeks) for up to 2 years, or six cycles of platinum plus pemetrexed chemotherapy. This report includes updated efficacy and safety outcomes, exploratory biomarker analyses including four-gene inflammatory expression signature score, and a post hoc efficacy analysis in patients who discontinued treatment due to treatment-related adverse events (TRAEs). Results: With a median follow-up of 43.1 months, nivolumab plus ipilimumab continued to prolong OS versus chemotherapy. Median OS was 18.1 versus 14.1 months [hazard ratio (95% confidence interval), 0.73 (0.61–0.87)], and 3-year OS rates were 23% versus 15%, respectively. Three-year progression-free survival rates were 14% versus 1%, and objective response rates were 40% versus 44%. At 3 years, 28% versus 0% of responders had an ongoing response. Improved survival benefit with nivolumab plus ipilimumab versus chemotherapy was observed across subgroups, including histology. A high score of the four-gene inflammatory signature appeared to correlate with improved survival benefit with nivolumab plus ipilimumab. No new safety signals were observed with nivolumab plus ipilimumab, despite patients being off therapy for 1 year. In patients who discontinued nivolumab plus ipilimumab due to TRAEs, median OS was 25.4 months, and 34% of responders maintained their responses for ≥3 years after discontinuation. Conclusions: With 3 years’ minimum follow-up, nivolumab plus ipilimumab continued to pr

The soil baseline program began in 1980 and is part of the Ministry of Environment's Acidic Precipitation in Ontario Study (A.P.I.O.S.). Over 300 locations were sampled in 1980 and 1981 throughout the province. Soil samples were analyzed at the Ministry's laboratory for pH, texture, iron, aluminum carbonates, major cations, anions and trace metals. A reliable, current and uniform data base for soils across Ontario now exists and is presented in Volumes 2 (Analytical Data for Southern Ontario) and 3 (Analytical Data for Northern Ontario) of this report. This data base is being used by A.P.I.O.S. researchers to design laboratory experiments which will define soil sensitivity criteria. Ultimately, a map will be produced which will show the relative sensitivities of Ontario soils to acidic deposition. Resampling baseline soil profiles over an extended period also provides a means of monitoring trends in soil chemistry due to environmental stress. This report is mainly a presentation of field and laboratory soil information (Volumes 2 and 3). The major objectives of the soil baseline program and methods used to sample soils are provided in Volume 1. In addition, the glacial history of Ontario, some theories of soil development, and the effect of acidic precipitation on soils are briefly outlined in Volume 1.

The soil baseline program began in 1980 and is part of the Ministry of Environment's Acidic Precipitation in Ontario Study (A.P.I.O.S.). The major objectives of the soil baseline program and methods used to sample soils are provided in Volume 1. In addition, the glacial history of Ontario, some theories of soil development, and the effect of acidic precipitation on soils are briefly outlined in Volume 1. Over 300 locations were sampled in 1980 and 1981 throughout the province. A reliable, current and uniform data base for soils across Ontario now exists and is presented in Volumes 2 (Analytical Data for Southern Ontario) and 3 (Analytical Data for Northern Ontario) of this report. This data base is being used by A.P.I.O.S. researchers to produce a map which will show the relative sensitivities of Ontario soils to acidic deposition. Resampling baseline soil profiles over an extended period will also provide a means of monitoring trends in soil chemistry due to environmental stress. This report is mainly a presentation of field and laboratory soil information (Volumes 2 and 3). Each baseline site has been given a 6 digit location code number. Within each region, sites are presented in ascending order based on location code number. The numbers which appear on Maps 3 to 8 in Volume I correspond to the last 3 digits of the location code. Soil samples were analyzed at the Ministry's central laboratory in Toronto for pH, texture, extractable iron, aluminum and manganese, inorganic and organic carbon, major cations (NaCl exchangeable), CEC (sum of cations measured), anions, and trace metals (HNO3 - HClO4 extractable). Further description of the analytical methods can be found in Volume 1 and in the "Procedures Manual Terrestrial Effects, Acid Precipitation in Ontario Study" (A.P.I.O.S.) Report No. 007/83 Ontario Ministry of the Environment. Data are reported to two significant figures. For the 14000, 17000 and 18000 series samples, organic carbon values were rounded to the nearest percent. This has since changed to provide better data at low levels.

- Abstract
Patients with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) primary breast cancer (BC) have low pathological complete response (pCR) rates with neoadjuvant chemotherapy. A subset of ER+/HER2- BC contains dense lymphocytic infiltration. We hypothesized that addition of an anti-programmed death 1 agent may increase pCR rates in this BC subtype. We conducted a randomized, multicenter, double-blind phase 3 trial to investigate the benefit of adding nivolumab to neoadjuvant chemotherapy in patients with newly diagnosed, high-risk, grade 3 or 2 (ER 1 to ≤10%) ER+/HER2- primary BC. In total, 510 patients were randomized to receive anthracycline and taxane-based chemotherapy with either intravenous nivolumab or placebo. The primary endpoint of pCR was significantly higher in the nivolumab arm compared with placebo (24.5% versus 13.8%; P = 0.0021), with greater benefit observed in patients with programmed death ligand 1-positive tumors (VENTANA SP142 ≥1%: 44.3% versus 20.2% respectively). There were no new safety signals identified. Of the five deaths that occurred in the nivolumab arm, two were related to study drug toxicity; no deaths occurred in the placebo arm. Adding nivolumab to neoadjuvant chemotherapy significantly increased pCR rates in high-risk, early-stage ER+/HER2- BC, particularly among patients with higher stromal tumor-infiltrating lymphocyte levels or programmed death ligand 1 expression, suggesting a new treatment paradigm that emphasizes the role of immunotherapy and T cell immunosurveillance in luminal disease.

- Abstract
We report herein, the discovery of BMS-737 (compound 33) as a potent, non-steroidal, reversible small molecule inhibitor demonstrating 11-fold selectivity for CYP17 lyase over CYP17 hydroxylase, as well as a clean xenobiotic CYP profile for the treatment of castration-resistant prostate cancer (CRPC). Extensive SAR studies on the initial lead 1 at three different regions of the molecule resulted in the identification of BMS-737, which demonstrated a robust 83% lowering of testosterone without any significant perturbation of the mineralocorticoid and glucocorticoid levels in cynomologous monkeys in a 1-day PK/PD study., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

- Abstract
Pharmacokinetic/pharmacodynamic (PK/PD) modeling was performed to quantitatively integrate preclinical pharmacology and toxicology data for determining the therapeutic index (TI) of an interleukin-10 (IL-10) fragment crystallizable (Fc) fusion protein. Mouse Fc fused with mouse IL-10 (mFc-mIL-10) was studied in mice for antitumor efficacy, and the elevation of interleukin-18 (IL-18) was examined as a PD biomarker. The in vivo mFc-mIL-10 EC
50 for the IL-18 induction was estimated to be 2.4 nM, similar to the in vitro receptor binding affinity (Kd ) of 3.2 nM. The IL-18 induction was further evaluated in cynomolgus monkeys, where the in vivo induction EC50 by a human IL-10 human Fc-fusion protein (hFc-hIL-10) was 0.08 nM vs. 0.3 nM measured as the in vitro Kd . The extent of the IL-18 induction correlated with mouse antitumor efficacy and was used to connect mouse efficacy to that in monkeys. The PD-based efficacious dose projected in monkeys was comparable to the results obtained using a PK-based method in which mouse efficacious exposure was targeted and corrected for affinity differences between the species. Furthermore, PK/PD relationships were developed for anemia and thrombocytopenia in monkeys treated with hFc-hIL-10, with thrombocytopenia predicted to be dose-limiting toxicity. Using quantitative pharmacology and toxicology information obtained through modeling work in the same species, the TI of hFc-hIL-10 in monkeys was determined to be 2.4 (vs. PD-based efficacy) and 1.2-3 (vs. PK-based efficacy), indicating a narrow safety margin. The model-based approaches were proven valuable to the developability assessment of the IL-10 Fc-fusion protein., Competing Interests: All authors are current or former employees of Bristol Myers Squibb and own or previously owned the company’s stocks., (Copyright © 2022 Yang, Loy, Poirson, Dai, Rajendran, Xu, Spires, Gururajan, Lin, Arbanas, Carl, Pace, Wang, Mehl, Vasudevan, Spires, Novosiadly, Coker, Perez, Covello, Morin, Graziano, Broz and Lehman-McKeeman.)- Published

- Abstract
Little data are available regarding the determinants and prognostic significance of serum albumin in Heart Failure with Preserved Ejection Fraction (HFpEF). We sought to examine the phenotypic correlates of albumin and its independent prognostic implications in HFpEF. We analyzed data from 3,254 subjects enrolled the TOPCAT trial. We stratified subjects according to tertiles of albumin and examined differences in various phenotypic traits between these strata, including 8 protein biomarkers selected ad hoc and measured from frozen samples available in a subset of participants (n = 372). We also assessed the relationship between albumin and the trial primary endpoint. Lower albumin was associated with older age, black race, and greater prevalence of NYHA class III-IV, peripheral arterial disease, atrial fibrillation and diabetes mellitus. Lower albumin was also associated with increased levels of several inflammatory biomarkers, markers of liver fibrosis, albuminuria, and greater arterial stiffness, diastolic dysfunction and pulmonary hypertension. Albumin was a strong predictor of the primary trial endpoint, even after adjustment for the MAGGIC risk score (hazard ratio [HR] 0.72, confidence interval [CI] 0.67 to 0.78; p <0.0001) and prespecified traditional risk factors (HR 0.78, CI 0.71 to 0.85; p <0.0001). Lower albumin was strongly associated with a worse prognosis even well within normal ranges (>3.5 g/dL), with a sharp increase in risk between 4.6 and 3.6 g/dL. In conclusion, albumin is an integrated marker of various adverse processes in HFpEF, including inflammation, subclinical liver disease, arterial stiffness, and renal disease. Albumin is a powerful risk predictor independent of traditional risk prediction models, even within normal ranges., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Purpose: Radiotherapy (RT) traditionally has been used for local tumor control in the treatment of cancer. The recent discovery that radiotherapy can have anticancer effects on the immune system has led to recognition of its ability to sensitize the tumor microenvironment to immunotherapy. However, radiation can also prompt adverse immunosuppressive effects that block aspects of systemic response at other tumor sites. Our hypothesis was that inhibition of the MER proto-oncogene tyrosine kinase (MerTK) in combination with anti-programmed cell death-1 (α-PD1) checkpoint blockade will enhance immune-mediated responses to radiotherapy., Experimental Design: We tested the efficacy of this triple therapy (Radiation + α-PD1 + α-MerTK mAbs) in 129Sv/Ev mice with bilateral lung adenocarcinoma xenografts. Primary tumors were treated with stereotactic radiotherapy (36 Gy in 3 12-Gy fractions), and tumors were monitored for response., Results: The triple therapy significantly delayed abscopal tumor growth, improved survival rates, and reduced numbers of lung metastases. We further found that the triple therapy increased the activated CD8
+ and NK cells populations measured by granzyme B expression with upregulation of CD8+ CD103+ tissue-resident memory cells (TRM ) within the abscopal tumor microenvironment relative to radiation only., Conclusions: The addition of α-PD1 + α-MerTK mAbs to radiotherapy could alter the cell death to be more immunogenic and generate adaptive immune response via increasing the retention of TRM cells in the tumor islets of the abscopal tumors which was proven to play a major role in survival of non-small cell lung cancer patients., (©2019 American Association for Cancer Research.)- Published

- Abstract
Extremely large carbon tubes, some exceeding 5 microm in diameter, were produced with both laser and electric arc techniques using graphite, a transition metal catalyst, and a reactive third-body gas. We have named these structures carbon megatubes. They are the first carbonaceous tubes large enough to observe using optical microscopy. We also report the synthesis of what we believe to be the first self-assembled branched nanotubes. In addition to their extreme diameters and unique morphologies, X-ray photoelectron spectroscopy has shown that these tubes also contain a significant amount of nitrogen atom incorporation into the graphite lattice. Subsequently, these nitrogen functionalities were shown to interact with rhenium pentacarbonyl bromide and serve as anchor points to tether molecules to the surface of the tubules.
