New Kidney Transplant Drug Cuts Risk of Earlier Death: Study

We know that, Belatacept (trade name Nulojix) is a fusion protein composed of the Fc fragment of a human IgG1 immunoglobulin linked to the extracellular domain of CTLA-4, which is a molecule crucial in the regulation of T-cell costimulation, selectively blocking the process of T-cell activation. It is intended to provide extended graft survival while limiting the toxicity generated by standard immune suppressing regimens, such as calcineurin inhibitors. It differs from abatacept (Orencia) by only 2 amino acids.
Belatacept was developed by Bristol-Myers-Squibb and approved by the U.S. Food and Drug Administration on June 15, 2011.
Now A newer drug used for preventing organ rejection might improve the long-term outlook for kidney transplant recipients, a new study finds.
Over seven years, patients given the drug belatacept (brand name: Nulojix) were 43 percent less likely to die or see their donor kidney fail compared to patients given an older drug called cyclosporine.
Experts said the findings should encourage more doctors and patients to choose belatacept over standard anti-rejection medications.
"This is a potentially transformational drug," said study lead researcher Dr. Flavio Vincenti, a transplant specialist at the University of California, San Francisco.
The study -- funded by the drug's maker, Bristol-Myers Squibb -- was published in the Jan. 28 issue of the New England Journal of Medicine.
Belatacept was first approved by the U.S. Food and Drug Administration in 2011 for preventing organ rejection after a kidney transplant. That was based on a three-year trial showing that the drug can prevent rejection in the shorter term, according to background information in the study.
Now the new findings prove what experts had hoped -- that belatacept would be better than cyclosporine in the long run, doctors said.

In continuation of my update on Halaven (eribulin mesylate)
Halaven (eribulin mesylate) has been approved by the U.S. Food and Drug Administration as the first chemotherapy drug shown to improve survival in people with advanced liposarcoma, a type of soft tissue sarcoma (cancer).
The drug is sanctioned for people who have received prior chemotherapy with a drug that contained anthracycline, the agency said Thursday in a news release.
Soft tissue sarcoma occurs when cancer invades soft tissues, such as muscles, tendons, fat, blood vessels, lymph nodes, nerves and tissues that surround joints, the FDA said. Liposarcoma specifically affects fat, most often of the head, neck, arms, legs, trunk or abdomen.
Halaven was evaluated in clinical studies involving more than 140 people with liposarcoma that had spread (metastatic) or couldn't be removed surgically. Average survival among people who took Halaven was 15.6 months, compared to 8.4 months among those who took another chemotherapy drug, dacarbazine.
The most common side effects of Halaven included fatigue, nausea, hair loss, constipation, nerve damage, abdominal pain and fever. Other adverse reactions included a drop in germ-fighting white blood cells and decreased levels of the minerals potassium or calcium.
More serious side effects included deadly infection, nerve damage, harm to a pregnant woman's fetus, and dangerous heartbeat abnormalities, the FDA said.

Diet rich in fiber may reduce risk of developing lung disease

A diet rich in fiber may not only protect against diabetes and heart disease, it may reduce the risk of developing lung disease, according to new research published online, ahead of print in the Annals of the American Thoracic Society.

Analyzing data from the National Health and Nutrition Examination Surveys, researchers report in "The Relationship between Dietary Fiber Intake and Lung Function in NHANES," that among adults in the top quartile of fiber intake:

•68.3 percent had normal lung function, compared to 50.1 percent in the bottom quartile.
•14. 8 percent had airway restriction, compared to 29.8 percent in the bottom quartile.

In two important breathing tests, those with the highest fiber intake also performed significantly better than those with the lowest intake. Those in the top quartile had a greater lung capacity (FVC) and could exhale more air in one second (FEV1) than those in the lowest quartile.


"Lung disease is an important public health problem, so it's important to identify modifiable risk factors for prevention," said lead author Corrine Hanson PhD, RD, an associate professor of medical nutrition at the University of Nebraska Medical Center. "However, beyond smoking very few preventative strategies have been identified. Increasing fiber intake may be a practical and effective way for people to have an impact on their risk of lung disease."

Sunitinib versus everolimus trial highlights non-clear cell RCC patient response heterogeneity


Sunitinib.svg


In continuation of my update on Sunitinib

Sunitinib offers significantly longer progression-free survival (PFS) than everolimus for patients with metastatic non-clear cell renal cell carcinoma (RCC), phase II trial results indicate, but treatment effect appears to depend upon key patient characteristics.

“Based on the present study and previous clinical studies, decisions on therapeutic choice between sunitinib and everolimus for patients with metastatic non-clear cell [RCC] should be based on prognostic risk criteria, histological subtype, and the known, expected side-effects”, say Andrew Armstrong, from Duke University in Durham, North Carolina, USA, and co-workers.
“Future clinical trials in these patients should also consider this heterogeneity of outcome when assessing novel agents”, they recommend in The Lancet Oncology. PFS was 8.3 months for the 51 patients randomly assigned to receive open-label, 6-week cycles of treatment with the VEGF receptor inhibitor sunitinib 50 mg/day compared with 5.6 months for the 57 patients given the mTOR inhibitor everolimus 10 mg/day, giving a significant hazard ratio (HR) of 1.41.

CGP3466B compound may effectively treat depression



Omigapil skeletal.svg


We know that, Omigapil (TCH346 or CGP3466) is a drug that was developed by Novartis and tested in clinical trials for its ability to help treat Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). The development for PD and ALS have been terminated due to lack of benefit, but Santhera Pharmaceuticals bought the compound for development for the treatment of congenital muscular dystrophy (CMD). Omigapil was first synthesized at Ciba-Geigy, Basel, Switzerland. Santhera Pharmaceuticals has since taken over production of omigapil and preclinical trials for CMD. In May 2008, omigapil was granted orphan designation to commence clinical trials for. Pharmacokinetic trials are scheduled to commence enrollment in the second half of 2012 to determine the appropriate pharmacokinetic profile of the drug for children with laminin-α2-deficient congenital muscular dystrophy (MDC1A) and collagen VI related myopathy. Santhera Pharmaceuticals will use the phase 1 clinical trial to determine if the drug is safe and acts with the same pharmacokinetic profile in children as it does in adults. The impending clinical trial will take place in the United States at the National Institute of Neurological Disorders and Stroke/National Institute of Health(NNDCS/NINDS) (Bethesda, Maryland) and in the United Kingdom at Great Ormond Street Hospital (UCL

The compound CGP3466B, already proven nontoxic for people, may effectively and rapidly treat depression, according to results of a study in mice. The Johns Hopkins Medicine neuroscientists who conducted the research say that the compound -- previously shown to block cocaine craving in the brains of rodents -- delivers antidepressant effects to mice within hours instead of weeks or months, like currently available antidepressants. The results of the study will be summarized Jan. 12 online in the journal Molecular Psychiatry.

"One of the promising things about CGP3466B is that it targets a new network of proteins," says Solomon Snyder, M.D., professor of neuroscience at the Johns Hopkins University School of Medicine. "That means it may work in patients who are unresponsive to other types of drugs and it lays the foundation for the development of a new class of fast-acting antidepressants that target the same network."

The team's discovery came out of investigations into the workings of a different drug, ketamine, long used primarily at high doses to induce anesthesia during surgery but known, at lower doses, to be a fast-acting antidepressant. Unfortunately, Snyder says, ketamine is addictive and can produce schizophrenialike symptoms, making it unsuitable for prolonged use, but his team hoped it could shed light on how to make a better fast-acting antidepressant.

UTA chemists design efficient water-based system for synthesis of organic compounds

Chemists at The University of Texas at Arlington have devised a safer, more environmentally friendly, less expensive and more efficient water-based system for the synthesis of organic compounds typically used in pharmaceuticals, agrochemicals, cosmetics, plastics, textiles and household chemicals.

Most organic synthesis depends heavily on volatile organic solvents, which typically pose significant environmental and health hazards and also are costly.

"Our new system could facilitate cheaper, safer and more efficient industrial reactions across a variety of sectors dependent on synthesis of organic compounds," said Morteza Khaledi, dean of UTA's College of Science and co-investigator of the project. "Using water as a solvent is ideal as it is benign, plentiful, cheap and not harmful to the environment."

The new medium, 80-90 percent water with fluoroalcohol, supports the synthetic reaction of organic compounds and even produces considerably higher yields of product than pure organic solvents.

The system also demonstrates the additional advantage that the mixture forms two separate phases during the reaction, which means that the resulting products can be easily separated and centrifuged out of the mixture. Typically, additional organic solvents are used to facilitate the separation and extraction of product.

"This is a clear step forward towards a "green" organic synthesis process and fits into UTA's strategic focus on Global Environmental Impact within the Strategic Plan 2020," Dean Khaledi said. "The organic solvent can even be recycled after the reaction, which is an additional bonus for the environment. "

New oral breast cancer drug has potential to combat other types of cancer

In continuation of my update on Palbociclib

Palbociclib.svg

Palbociclib, a new oral drug whose efficacy in combating breast cancer has been demonstrated alone and in combination with endocrine therapy, also has potential to combat other types of cancer, according to a literature review and additional original research conducted by experts at the Abramson Cancer Center (ACC) in the University of Pennsylvania published this month in JAMA Oncology.

Palbociclib targets the rapid division of tumor cells by inhibiting the activity of the enzymes CDK4 and CDK6, which propel cell division and increase in number in most cancers. It is the first CDK4/6 inhibitor to be approved for the treatment of breast cancer.

"All living cells undergo cell division and palbociclib's unique capacity to halt the cell division process (also known as the 'cell cycle') therefore has potentially broad applicability," said the study's lead author Amy S. Clark, MD, MSCE, an assistant professor of Hematology/Oncology at Penn's Perelman School of Medicine and ACC. "Pairing palbociclib with other anti-cancer therapies such as endocrine therapy, chemotherapy, and targeted therapy can create a powerful combinatorial effect with real promise for addressing a variety of cancers." For example, amplification of CDK4 is reported in a high percentage of melanomas and esophageal cancers.
Targeted therapy uses medication and other interventions to more accurately identify and attack cancer cells, usually while doing no or little damage to normal cells.

"This drug has minor effects on normal cells other than neutrophils (white blood cells)," said the study's senior author, Peter J. O'Dwyer, MD, a professor of Hematology/Oncology at Penn and director of the Developmental Therapeutics Program at the ACC. "In tumors, it can cause shrinkage, or more commonly, arrest of growth. As we discover new functions for the CDK4/6 target of this medicine, we are likely to use it in combinations to make other anti-cancer agents work better."

Potent parasite-killing mechanism of anti-malarial drug uncovered: New understanding of how artemisinin works could facilitate development of new drugs and therapeutic strategies against malaria -- ScienceDaily

In continuation of my update on artemisinin

Artemisinin.svg
A team of researchers has uncovered the mystery behind the potent parasite-killing effect of artemisinin, a drug that is considered to be the last line of defense against malaria. Given the emergence of artemisinin resistance, these findings could potentially lead to the design of new treatments against drug-resistant parasites.



Assistant Professor Lin Qingsong, who is from the Department of Biological Sciences under the NUS Faculty of Science and is one of the scientists who led the study, explained, "Many people may not realise that more human lives are lost to the tiny mosquito, more specifically malaria parasites, each year as compared to ferocious animals such as lions and sharks. After infection, malaria parasites, known for their blood-eating nature, can propagate inside the human body rapidly and consume up to 80 per cent of red blood cells in a short period of time, leading to a series of deadly symptoms."
About 3.2 billion people -- almost half of the world's population -- are considered to be at risk of malaria by the World Health Organization. As of September 2015, there were an estimated 214 million cases of malaria and 438,000 malaria-linked deaths this year alone.
Artemisinin and its derivatives are currently the most potent class of anti-malarial drugs. In recognition of its importance against malaria, the discovery of artemisinin won Chinese scientist Ms Tu Youyou the 2015 Nobel Prize in Physiology or Medicine earlier in October this year. While there have been extensive studies on artemisinin, the mechanism of the drug is not well understood.
Asst Prof Lin, together with Dr Wang Jigang, who was formerly with the NUS Department of Biological Sciences and now with the Singapore-MIT Alliance for Research & Technology, Associate Professor Kevin Tan from the Department of Microbiology and Immunology at the NUS Yong Loo Lin School of Medicine and their research team, discovered over 120 protein targets of artemisinin, and the mechanism that activates its deadly killing effect. The findings of the study are published in the journal Nature Communications on 23 December 2015.

New Breast Cancer Drug May Be Effective Against Other Types of Cancer, Abramson Cancer Center Experts Find



Palbociclib.svg
In continuation of my update on Palbociclib,



Palbociclib, a new oral drug whose efficacy in combating breast cancer has been demonstrated alone and in combination with endocrine therapy, also has potential to combat other types of cancer, according to a literature review and additional original research conducted by experts at the Abramson Cancer Center (ACC) in the University of Pennsylvania published this month in JAMA Oncology.


Palbociclib targets the rapid division of tumor cells by inhibiting the activity of the enzymes CDK4 and CDK6, which propel cell division and increase in number in most cancers. It is the first CDK4/6 inhibitor to be approved for the treatment of breast cancer.
“All living cells undergo cell division and palbociclib’s unique capacity to halt the cell division process (also known as the ‘cell cycle’) therefore has potentially broad applicability,” said the study’s lead author Amy S.

As we discover new functions for the CDK4/6 target of this medicine, we are likely to use it in combinations to make other anti-cancer agents work better.”

In addition to inhibiting the cell cycle, palbociclib has been shown, for example, to alter several recently described non–cell cycle functions of CDK4/6, a finding expected to expand its therapeutic role, O’Dwyer added.

Assessing 130 relevant publications in the literature, as well as interpreting their own continuing studies, the all-Penn team found that in addition to its safety and effectiveness in fighting certain types of breast cancer, early trials of palbociclib have shown promise of effectiveness in cases of lymphoma, sarcoma, and teratoma, tumors that while rare, often afflict younger patients.

A phase 2 trial showed that, among 17 patients with previously treated mantle-cell lymphoma, palbociclib resulted in one complete response and two partial responses. Although, median progression-free survival was four months, five patients had progression-free survival greater than one year. Another phase 2 trial with 29 sarcoma patients treated with palbociclib showed a progression-free survival of 66 percent at 12 weeks.
Also, combining palbociclib with other anti-cancer agents is feasible, and early results in myeloma and some solid tumors have led to more definitive studies.

Afatinib a better choice for EGFR-mutated lung cancer in first-line treatment



Afatinib2DACS.svg


In continuation of my update on Afatinib



Patients with EGFR-activating mutations in advanced lung cancer seem to benefit more from afatinib than gefitinib as first-line treatment, researchers report at the first ESMO Asia 2015 Congress in Singapore.

In the global, randomised, open-label Phase IIb LUX-Lung 7 (LL7) trial1, the irreversible ErbB family blocker afatinib significantly improved efficacy versus gefitinib across a range of clinically relevant endpoints, such as progression-free survival, time-to-treatment failure and objective response rate. "Based on these results I would consider afatinib as the EGFR tyrosine kinase inhibitor (TKI) of choice for the first-line treatment for patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC)," lead author, Professor Keunchil Park, head of the Division of Hematology/Oncology at Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea, said.

NSCLC is the most common type of lung cancer: activating epidermal growth factor receptor (EGFR) gene mutations are more frequently observed in non-smokers and women, and occur in 50% of Asians and only 10% of non-Asians. The targeted agents afatinib and gefitinib block key pathways involved in tumour growth and spread. They have both been approved for the treatment of naive patients, based on the results of Phase III trials, confirming their superiority compared to chemotherapy. Unlike the first-generation EGFR inhibitor gefitinib, the irreversible ErbB family blocker afatinib is suggested to be active in prolonging tumour response and delaying disease progression.

Osteoarthritis: pivotal Phase III trial successfully meets primary efficacy endpoint - Medical News Today

Celecoxib/amlodipine besylate (KIT-302)

  

itov Pharmaceuticals, an innovative biopharmaceutical company focused on late-stage drug development, announced today that the Phase III, double-blind, placebo-controlled clinical trial for its leading drug candidate, KIT-302, successfully met the primary efficacy endpoint of the trial protocol as approved by the U.S. Food & Drug Administration (FDA). Data from the trial further revealed that KIT-302 was more efficacious at reducing hypertension than the widely used hypertension drug amlodipine besylate. Kitov plans to file its New Drug Application (NDA) for marketing approval of KIT-302 with the FDA in the second half of 2016.

A combination drug, KIT-302, simultaneously treats pain caused by osteoarthritis and treats hypertension, which is a common side effect of stand-alone drugs that treat osteoarthritis pain. KIT-302 is comprised of two FDA approved drugs, celecoxib (Celebrex®) for the treatment of pain caused by osteoarthritis and amlodipine besylate, a drug designed to treat hypertension.

The trial protocol, approved by the FDA through the Special Protocol Assessment process, was designed to quantify the decrease of hypertension in patients receiving KIT-302. The trial was performed in the U.K. in four groups of twenty-six (26) to forty-nine (49) patients, with a total of 152 patients. Each patient was treated over a total period of two weeks. Group One was treated with KIT-302, comprised of celecoxib and amlodipine besylate. Group Two was treated with amlodipine besylate only, one of the components of KIT-302. Group Three was treated with celecoxib only, the other component of KIT-302. Group Four was treated with a double placebo. The trial began in June 2014 and was completed in November 2015.

FDA Approves Bridion (sugammadex) to Reverse Effects of Neuromuscular Blocking Drugs

"Bridion provides a new treatment option that may help patients recover sooner from medications used for intubation or ventilation during surgery,” said Sharon Hertz, The U.S. Food and Drug Administration today approved Bridion (sugammadex) injection to reverse the effects of neuromuscular blockade induced by rocuronium bromide and vecuronium bromide, which are used during certain types of surgery in adults.

Rocuronium bromide and vecuronium bromide are neuromuscular blocking drugs that cause temporary paralysis by interfering with the transmission of nerve impulses to the muscle and are used to paralyze the vocal cords when patients require an artificial airway or breathing tube for surgery, a process called tracheal intubation. They can also be used to prevent patients from moving during surgery while they are receiving general anesthesia. Neuromuscular blocking drugs are also sometimes used to prevent the body from breathing automatically when a patient has to be placed on a ventilator.
