Aeterna Zentaris Announces Top-Line Results of Confirmatory Phase 3 Trial of Macrilen™

Source: http://www.businesswire.com/
CHARLESTON, S.C.--(BUSINESS WIRE)--Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZ) (the “Company”) today announced that the confirmatory Phase 3 clinical trial of Macrilen™ (macimorelin) failed to achieve its objective of validating a single oral dose of macimorelin for the evaluation of growth hormone deficiency in adults (“AGHD”), using the insulin tolerance test (the “ITT”) as a comparator. The Company is evaluating the outcome of the trial and will determine in the near future whether it will continue with the development of Macrilen™.

Dr. Richard Sachse, the Company’s Chief Scientific Officer, stated, “We are, of course, very disappointed about the outcome of the trial. Based on an analysis of top-line data, macimorelin did not achieve equivalence to the ITT as a means of diagnosing AGHD. Under the study protocol, the evaluation of AGHD with Macrilen™ would be considered successful, if the lower bound of the two-sided 95% confidence interval for the primary efficacy variables was 75% or higher for “percent negative agreement” with the ITT, and 70% or higher for the “percent positive agreement” with the ITT. While the estimated percent negative agreement met the success criteria, the estimated percent positive agreement did not reach the criteria for a successful outcome. Therefore, the results did not meet the pre-defined equivalence criteria which required success for both the percent negative agreement and the percent positive agreement. After a thorough internal review and understanding of this data, the Company will decide upon the appropriate future course of action with respect to macimorelin.”

AstraZeneca and Lilly to develop treatment for Alzheimer’s disease

Source: https://www.astrazeneca.com/
AstraZeneca and Eli Lilly and Company today announced a worldwide agreement to co-develop MEDI1814, an antibody selective for amyloid-beta 42 (Aβ42), which is currently in Phase I trials as a potential disease-modifying treatment for Alzheimer’s disease (AD). This agreement builds on the existing collaboration related to AZD3293, a BACE inhibitor in two pivotal Phase III trials.

The build-up of plaques in the brain containing the peptide amyloid-beta (Aβ) is one of the characteristics of AD. MEDI1814 binds selectively to Aβ42, a form of Aβ which is particularly associated with the disease. MEDI1814 dose-dependently reduces levels of this peptide, potentially slowing the progression of AD.

Mene Pangalos, Executive Vice President, IMED Biotech Unit and Business Development, AstraZeneca, said: “We are excited to build on an already productive collaboration with Lilly, which combines the expertise of our two companies, with a new programme focused on the amyloid beta pathway. MEDI1814 has a unique mechanism among antibodies in clinical development and could provide a distinct approach to treating Alzheimer’s disease.”

OPKO Health Provides Update on hGH-CTP Clinical Programs

Source: OPKO Health Inc. & reported by https://globenewswire.com/
MIAMI, Dec. 30, 2016 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ:OPK) announced it has commenced data analysis in the phase 3, double-blind, placebo-controlled study of its investigational long-acting human growth hormone product (hGH-CTP) in adults with growth hormone deficiency (GHD). The multinational, multi-center study, which utilized a 2:1 randomization between hGH-CTP and placebo, enrolled 203 subjects, 198 of whom received at least one dose of study treatment. Treatment was administered through a weekly injection.

On the primary endpoint of change in trunk fat mass from baseline to 26 weeks, there was no statistical difference between hGH-CTP and placebo. However, after unblinding the study, OPKO identified one or more outliers that may have affected the primary outcome. As a result, OPKO is undertaking further review of the study population as promptly as possible. The safety profile observed in this study was consistent with that known for growth hormone treatments. A greater percentage of subjects on hGH-CTP normalized serum concentrations of insulin-like growth factor-I compared to placebo. Additional efficacy and safety data and analyses from the study will be released once available.

New mechanobiology technique to stop cancer cell migration

Researchers at the Okinawa Institute of Science and Technology Graduate university (OIST) have developed a novel technique that stops cervical cancer cell migration. The research, published in Chem could open up new avenues in cancer treatment.
The ability of cancer cells to change position within body tissues through cell migration and invasion represents the biggest threat of cancer to human health.
Traditionally, scientists have tried to approach the problem of cancer migration by targeting molecules inside cancer cells, but finding an appropriate target has proved challenging.
"We developed a technique that targets lipid rafts on cancer cell membranes," says Professor Ye Zhang from OIST's Bioinspired Soft Matter Unit, who led the research.
Lipid rafts are free-floating domains within the cell membrane that act as platforms for communication between the outside and inside of a cell. They are associated with the cell cytoskeleton—a complex network of interlinking filaments inside the cell that is necessary for cell migration—making them viable targets for inhibiting migration.
Dr. Guanying Li and Professor Zhang worked with colleagues from OIST's Imaging and Instrument Analysis Section, as well as scientists in the SM Application Group of JEOL in Tokyo.
New mechanobiology technique to stop cancer cell migration
The cancer-busting molecule synthesized by Zhang's team (a) interacts with GPI-anchored PLAP on the lipid rafts of cervical cancer cells and undergoes self-assembly into nanofibrils (b). As the cancer cell tries to migrate, away, more …more
The team designed and synthesized a luminescent molecule that recognizes cervical cancer cells and physically stops them from migrating. The molecule consists of a ruthenium metal complex core with three self-assembly peptide building blocks attached in a three-dimensional structure.
When these building blocks interact with a cervical cancer biomarker known as glycosylphosphatidylinositol-anchored placental alkaline phosphatase, or GPI-anchored PLAP, which is located on lipid rafts, they self-assemble into nano-scale chains, or 'nanofibrils', that glue lipid rafts into large clusters. Consequently, the associated cytoskeleton components get tied up, pinning the cancer cell on the substrate and preventing it from moving at that site.
In response, the cancer cell tries to migrate away from the immobilized site, extending projections called filopodia in the new direction of migration. Lipid rafts cluster on the filopodia tips, becoming the new sites of molecule self-assembly, that results in the pinning of the cancer cell at a second site.
This process continues as the cancer cell tries to migrate away from these immobilized regions. Progressively, the cancer cell expands its body in an attempt to escape immobilization, but the cell margins remain fixed by the nanofibrils, its body is stretched flat. The opposing stretch forces cause the cell to rupture, which leads to cell death.
Professor Zhang's team were able to visualize the pinning, stretching and rupturing of cervical cancer cells by immunostaining different parts of the cells and viewing them under a confocal fluorescent microscope and a high-resolution scanning electron microscope (SEM).
"Our research opens a window in cervical cancer therapy," says Professor Zhang. "We have shown that our molecule works on cancer cells in the lab, but the next step is to see if it works on real tumors in animals. As different cancers express different biomarkers, it might be possible to modify the molecular structure of the ruthenium molecule to target different types of cancer cell."

Optimized syntheses of Fmoc azido amino acids for the preparation of azidopeptides

The rise of CuI-catalyzed click chemistry has initiated an increased demand for azido and alkyne derivatives of amino acid as precursors for the synthesis of clicked peptides. However, the use of azido and alkyne amino acids in peptide chemistry is complicated by their high cost. For this reason, we investigated the possibility of the in-house preparation of a set of five Fmoc azido amino acids: β-azido l-alanine and d-alanine, γ-azido l-homoalanine, δ-azido l-ornithine and ω-azido l-lysine. We investigated several reaction pathways described in the literature, suggested several improvements and proposed several alternative routes for the synthesis of these compounds in high purity. Here, we demonstrate that multigram quantities of these Fmoc azido amino acids can be prepared within a week or two and at user-friendly costs. We also incorporated these azido amino acids into several model tripeptides, and we observed the formation of a new elimination product of the azido moiety upon conditions of prolonged couplings with 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate/DIPEA. We hope that our detailed synthetic protocols will inspire some peptide chemists to prepare these Fmoc azido acids in their laboratories and will assist them in avoiding the too extensive costs of azidopeptide syntheses.
