Nanomagnets clean blood
Nanoparticles latch onto toxins in blood but are magnetically trapped before they can enter the body
http://www.rsc.org/chemistryworld/2013/07/nanomagnets-clean-blood
The group used their extracorporeal circuit to remove lead and the drug digoxin from the blood of rats. Target compounds in blood adhered to the nanoparticles as they collided within the circuit. The nanoparticles were then collected by magnetic separation with the toxin immobilised on the particle surface before blood could re-enter the body.

The European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the EU. A legal framework for approving biosimilars was established in 2003. Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or ‘reference drug’.

International nonproprietary name: Filgrastim
Chemical name: N-L- Methionyl colony-stimulating factor (human genetically engineered); non-glycated protein consisted of 175 amino acids.
Chemical name: N-L- Methionyl colony-stimulating factor (human genetically engineered); non-glycated protein consisted of 175 amino acids.
Filgrastim is a granulocyte colony-stimulating factor (G-CSF) analog used to stimulate the proliferation and differentiation of granulocytes.[1] It is produced by recombinant DNA technology. The gene for human granulocyte colony-stimulating factor is inserted into the genetic material of Escherichia coli. The G-CSF then produced by E. coli is different from G-CSF naturally made in humans.
Hematopoietic growth factor. Interacting with receptors on the surface of hematopoietic cells it regulates production and release of neutrophils from the bone marrow to the peripheral blood. Dose dependant number growth of neutrophils with normal or increased functional activity is passing for 24 hours.
Filgrastim is marketed under several brand names, including Neupogen (Amgen), Imumax(Abbott Laboratories), Grafeel (Dr. Reddy’s Laboratories), Neukine (Intas Biopharmaceuticals), Emgrast (Emcure Pharmaceuticals), Religrast (Reliance Life Sciences), Zarzio (Sandoz), Nufil (Biocon) and others.
Apricus Biosciences is currently developing and testing a product under the brand nameNupen which can deliver filgrastim through the skin to improve post-chemotherapy recovery of neutrophil counts.
Filgrastim is also used to increase the number of hematopoietic stem cells in the blood before collection by leukapheresis for use in hematopoietic stem cell transplantation.Filgrastim is used to treat neutropenia,[2] stimulating the bone marrow to increase production of neutrophils. Causes of neutropenia include chemotherapy and bone marrow transplantation.
Filgrastim should not be used in patients with known hypersensitivity to E. coli-derived proteins.
The most commonly observed adverse effect is mild-to-moderate bone pain after repeated administration and local skin reactions at the site of injection.[3] Other observed adverse effects include serious allergic reactions (including a rash over the whole body, shortness of breath, wheezing, dizziness, swelling around the mouth or eyes, fast pulse, and sweating), ruptured spleen (sometimes resulting in death), alveolar hemorrhage, acute respiratory distress syndrome, and hemoptysis.[3] Severe sickle cell crises, in some cases resulting in death, have been associated with the use of filgrastim in patients with sickle cell disorders.[4]
Drug interactions between filgrastim and other drugs have not been fully evaluated. Drugs which may potentiate the release of neutrophils‚ such as lithium‚ should be used with caution.
Increased hematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone imaging changes; this should be considered when interpreting bone-imaging results.[5]
Filgrastim has not been studied in pregnant women and its effects on unborn babies is unknown. If taking filgrastim while pregnant, it is possible that traces of the drug could be found in the baby’s blood. It is not known if the drug can get into human breast milk.
Afutuzumab
Genentech announced positive results from the Phase 3 CLL11 study. At a pre-planned interim analysis, an independent data monitoring committee determined that the study met its primary endpoint showing that GA101 plus chlorambucil helped people live significantly longer without their disease worsening (progression-free survival; PFS) compared to Rituxan (rituximab) plus chlorambucil.
The CLL11 study is being conducted in cooperation with the German CLL Study Group (GCLLSG). These final data were reached well ahead of the target completion date in 2014 as a result of the magnitude of difference seen between the two study arms.
Afutuzumab is a monoclonal antibody being developed by Hoffmann-La Roche Inc. for the treatment of lymphoma.[1] It acts as an immunomodulator.[2][3] It was renamed obinutuzumab in 2009.[4]
Class/mechanism: Glyco-engineered anti-CD20 IgG1 type II monoclonal antibody. Engineered with a modified elbow hinge residue (valine instead of leucine at Kabat position 11) and a glyco-engineered Fc region, which is postulated to enhance its immunomodulatory effect.[1]
Route: IV
Extravasation: no information

Roche has announced that its experimental leukemia drug GA101, or obinutuzumab, used in combination with chemotherapy, was better than Rituxan at helping people with chronic lymphocytic leukemia live longer without their disease worsening, according to the results from the second phase of the clinical trial. Both drugs were tested and compared in combination with chlorambucil.
The trial, named CLL11, is a phase III, multicenter, open-label, randomized three-arm study investigated in 781 previously untreated people with chronic lymphocytic leukemia and co-existing medical conditions who are in need of therapy. The study included two stages of analysis, with the first stage results being reported at the start of this month. Data from the first stage showed that patients taking Obinutuzumab had a 86%reduction in the risk of disease worsening or death when combined with chlorambucil chemotherapy compared to chlorambucil alone in previously untreated people with chronic…

Evaluate Pharma has released today their sixth edition of their series EvaluatePharma’s World Preview. Like always, it is filled with high-quality data on the (mostly) post-patent cliff world that we live in, worthy of a careful read. Some highlights of the report follow:

Alkermes has unveiled three new drug candidates, including: a monomethyl fumarate (MMF) prodrug programme for the treatment of multiple sclerosis; ALKS 7106 for the treatment of pain; and RDB 1419, a cancer immunotherapy candidate based on interleukin-2 (IL-2) and its receptors, Alkermes’ first proprietary biologic.
According to Alkermes, these drug candidates demonstrate the company’s focus on unmet medical needs in specific patient populations and show the productivity of its expanded R&D capabilities.

There are a number of medical treatments available to manage ulcerative colitis. Modern therapy is targeted at preventing flares and inducing remission (at least temporarily). These medications, however, have serious side effects, especially when taken for long periods. Corticosteroids, for example, can cause a number of cosmetic, psychological, and hormonal problems. Many patients simply cannot tolerate these medications. Children have particular problems with standard medications. When compliance with prescribed medicines is poor, treatment failure is common.1,2 Thus, many patients turn to natural remedies for their ulcerative colitis..http://www.drugs.com/health/ulcerative-colitis/natural-remedy-1234/#1
Some herbal or organic remedies may help promote gut health and prolong the time between remissions (flares).
A few well-known home remedies for the management of ulcerative colitis include:
