Naproxen and omeprazole combination effective in preventing bladder cancer

The anti-inflammatory class of drugs NSAIDs have shown great promise in preventing cancers including colon, esophagus and skin. However, they can increase the risks of heart attacks, ulcers and rare but potentially life-threatening bleeds.

A new study suggests there may be ways to reduce these dangerous side effects. Collaborators from the University of Michigan, the National Cancer Institute and the University of Alabama looked at naproxen, which is known to have a lower cardiovascular risk than other NSAIDs. Naproxen, like most NSAIDs and aspirin, does increase the risk for gastric ulcers or bleeding. Here, the researchers used the proton pump inhibitor omeprazole, a commonly used acid inhibitor, in combination with naproxen and tested its effects on cancer prevention in a rat model of bladder cancer.

They found that naproxen reduced the incidence of bladder cancer by 75 percent in rats. Omeprazole by itself did not affect the development of cancer but it also did not interfere with the effect of naproxen at preventing tumors. The rats who received naproxen alone or naproxen with omeprazole developed cancer at similarly low rates, while all rats receiving omeprazole alone or no treatment developed bladder cancer.

Clinical data in humans has previously shown combining omeprazole plus naproxen reduced gastric toxicity roughly 70 percent.

The authors also found that intermittent dosing with naproxen (three weeks on the drugs, followed by three weeks off) was highly effective and likely to reduce gastric toxicity. However, it does not have the clear clinical data supporting reduced gastric toxicity associated with naproxen and omeprazole.

"Our study shows that naproxen works just as well with a proton pump inhibitor as without. This provides proof of principle that this could be a valuable cancer prevention strategy and one hopes it can advance quickly to a clinical trial for those at high risk of colon, esophageal, squamous cell skin cancer or potentially other cancers," says lead study author Ronald A. Lubet, Ph.D., a scientist with the Chemopreventive Agent Development Research Group at the National Cancer Institute.

New drug shows promise in driving insulin-producing beta cells to multiply

In a screen of more than 100,000 potential drugs, only one, harmine, drove human insulin-producing beta cells to multiply, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai, funded by JDRF and the National Institutes of Health, and published online today in Nature Medicine.

Diabetes results from too few insulin-producing "beta cells" in the pancreas secreting too little insulin, the hormone required to keep blood sugar levels in the normal range. The disease affects 380 million people worldwide, and leads to major medical complications: heart attack, stroke, kidney failure, blindness and limb amputation.

The Mount Sinai study found that harmine drove the sustained division and multiplication of adult human beta cells in culture, a feat that had eluded the field for years. In addition, harmine treatment tripled the number of beta cells and led to better control of blood sugar in three groups of mice engineered to mimic human diabetes.

"Our results provide a large body of evidence demonstrating that the harmine drug class can make human beta cells proliferate at levels that may be relevant for diabetes treatment," said senior study author Andrew Stewart, MD, Director of the Diabetes, Obesity and Metabolism Institute at the Icahn School of Medicine. "While we still have a lot of work to do in improving the specificity and potency of the harmine and related compounds, we believe these results represent a key step toward more effective future treatment of diabetes."

Loss of insulin-producing beta cells has long been recognized as a cause of Type 1 diabetes, in which the immune system mistakenly attacks and destroys beta cells. In recent years, researchers have concluded that a deficiency of functioning beta cells also contributes importantly to Type 2 diabetes. Thus, developing drugs that can increase the numbers of healthy beta cells is a major priority in diabetes research.

New injectable polymer could strengthen blood clots

A 3D rendering of fibrin forming a blood clot, with PolySTAT (in blue) binding strands together


In the initial study with rats, 100 per cent of animals injected with PolySTAT survived a typically lethal injury to the femoral artery. Only 20 per cent of rats treated with a natural protein that helps blood clot survived.

“Most of the patients who die from bleeding die quickly,” said co-author Dr. Nathan White, an assistant professor of emergency medicine who teamed with UW bioengineers and chemical engineers to develop the macromolecule. “This is something you could potentially put in a syringe inside a backpack and give right away to reduce blood loss and keep people alive long enough to make it to medical care.”
According to a statement, the UW team was inspired by factor XIII, a natural protein found in the body that helps strengthen blood clots.
Normally after an injury, platelets in the blood begin to congregate at the wound and form an initial barrier. Then a network of specialised fibres called fibrin start weaving themselves throughout the clot to reinforce it.

New cancer drug enters phase I clinical trials in humans

"Even though they have elevated levels of procaspase-3, cancer cells never turn the enzyme on. So they keep growing and become tumors," he said. "PAC-1 restores the activity of procaspase-3 and, because the enzyme is elevated in cancer cells, it targets cancer cells over non-cancerous cells."  PAC-1.svg



A new drug that prompts cancer cells to self-destruct while sparing healthy cells is now entering phase I clinical trials in humans. The drug, called PAC-1, first showed promise in the treatment of pet dogs with spontaneously occurring cancers, and is still in clinical trials in dogs with osteosarcoma.

The compound was discovered and is being developed based on the hypothesis that most cancers have elevated levels of an enzyme called procaspase-3," said University of Illinois chemistry professor Paul Hergenrother, who discovered the anti-cancer effects of PAC-1 more than a decade ago. "Procaspase-3 is an enzyme that, when turned on, kills cells."

Cancer cells, however, override this normal cell-recycling pathway, he said.

Early tests of the drug's effectiveness came when Hergenrother collaborated with U. of I. veterinary clinical sciences professor Timothy Fan, who tested PAC-1 in his canine cancer patients. These clinical trials helped the researchers find the best way to deliver the drug - it is now in pill form for both human and canine patients - and led to new insights into the drug's activity and potential, Fan said.

EMA extends approval of Vectibix plus FOLFIRI as first-line treatment for wild-type RAS mCRC

Amgen (NASDAQ: AMGN) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion to extend the marketing authorization for Vectibix® (panitumumab) to include combination with FOLFIRI- FOLFIRI is a chemotherapy regimen for treatment of colorectal cancer. It is made up of the following drugs:
  • FOL – folinic acid (leucovorin), a vitamin B derivative used as a "rescue" drug for high doses of the drug methotrexate, but increases the cytotoxicity of 5-fluorouracil;
  • F – fluorouracil (5-FU), a pyrimidine analog and antimetabolite which incorporates into the DNA molecule and stops synthesis; and
  • IRI – irinotecan (Camptosar), a topoisomerase inhibitor, which prevents DNA from uncoiling and duplicating.
 (an irinotecan-based chemotherapy) as first-line treatment in adult patients with wild-type RAS metastatic colorectal cancer (mCRC). About half of the patients with mCRC have wild-type RAS tumors.

"Adding Vectibix to chemotherapy as first-line treatment in patients with wild-type RASmetastatic colorectal cancer has been shown to result in better responses than chemotherapy alone," said Elliott M. Levy, M.D., senior vice president of Global Development at Amgen. "The CHMP recommendation is an important step toward increasing the treatment options for patients with this aggressive disease and helping improve outcomes in the European Union."

EMA's CHMP backs JINARC (tolvaptan) for autosomal dominant polycystic kidney disease



Tolvaptan.svg


Tolvaptan (INN), also known as OPC-41061, is a selective, competitive vasopressin receptor 2 antagonist used to treat hyponatremia (low blood sodium levels) associated with congestive heart failurecirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). Tolvaptan was approved by the U.S. Food and Drug Administration (FDA) on May 19, 2009, and is sold by Otsuka Pharmaceutical Co. under the trade name Samsca and in India is manufactured & sold by MSN laboratories Ltd. under the trade name Tolsama & Tolvat and by Lupin under the brand name Resodim.
-------------------------------------------------------------------------------------------
Otsuka Pharmaceutical Co., Ltd. announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended JINARC® (tolvaptan) for approval. This treatment has been recommended to slow the progression of cyst development and renal insufficiency of autosomal dominant polycystic kidney disease (ADPKD) in adults with chronic kidney disease (CKD) stage 1 to 3 at initiation of treatment with evidence of rapidly progressing disease.

Tolvaptan was developed over a period of 26 years through the persevering efforts of researchers in Otsuka’s Japanese pharmaceutical research centre. Upon discovering a cell signaling pathway that causes renal cysts to proliferate and enlarge, Otsuka launched an effort in 2004 to develop a drug for the disease in conjunction with the world’s leading ADPKD medical specialists.

Study shows efficacy of YONDELIS (trabectedin) in patients with soft-tissue sarcoma


Trabectedin.png


In continuation of my update on trabectedin

PharmaMar announced that the European Journal of Cancer published online data from a large retrospective study with soft-tissue sarcoma (STS) patients carried out at 25 French centers confirming that in routine practice YONDELIS® (trabectedin) shows comparable or better clinical outcomes than those observed in clinical trials . The results add to previous evidence from other studies with trabectedin , including the compassionate expanded access program of 1895 patients with incurable disease , demonstrating that response and disease control rates are higher than expected. The authors describe that long-term treatment of multiple types of STS patients without progressive disease delayed progression and improved survival compared to those who stopped it after six cycles, as recently suggested in the T-DIS studyiii. In this routine real-life scenario, the median progression-free survival (PFS) and overall survival (OS) were 4.4 and 12.2 months, respectively after a median follow-up of 22 month. Of the 304 patients who achieved non-progressive disease after six cycles, 227 continued receiving trabectedin and obtained significant superior PFS (11.7 versus 7.6 months) and OS (24.9 versus 16.9 months) than those who did not. The recent study reinforces an approach of early administration of YONDELIS® (trabectedin) to optimize its efficacy as second-line treatment in patients that will probably benefit from this drug. Despite the limitations of the study, the investigators emphasize that this clinical strategy may achieve longer disease control without compromising the safety profile of the treatment, given that a third of the patients received more 6 or more cycles of the drug and were able to tolerate longer treatments.

Bionomics to present data from DisrupTOR-1 trial at ASCO Genitourinary Cancers Symposium



graphic




Bionomics Limited (ASX:BNO, ADR:BMICY) is to present important additional data from the DisrupTOR-1 trial of BNC105 in patients with metastatic renal cancer at the ASCO Genitourinary Cancers Symposium in Orlando, Florida. The data will be presented by Dr. Sumanta Pal of the City of Hope Comprehensive Cancer Center in California in his poster presentation.

The new data identifies Ferritin and IL-8 as two baseline biomarkers that correlate with an improved progression free survival (PFS) in patients. Elevated baseline Ferritin and lower baseline IL-8 were associated with improved PFS (P=0.0291 and P=0.0149, respectively). Eighty nine percent of patients expressing elevated plasma levels of Ferritin and lower plasma levels of IL8 at baseline were disease progression free (PFS) at 6 months.

"The DisrupTOR-1 trial offered a unique opportunity to assess biomarkers related to the activity of BNC105. Interestingly our findings suggest that baseline levels of Ferritin and IL-8 may predict an excellent clinical outcome with the combination of Afinitor with BNC105. Plans are underway already to validate this finding in a biomarker-driven trial," said Dr. Pal, Co-Director of the Kidney Cancer Program at the Department of Medical Oncology & Experimental Therapeutics of the City of Hope Comprehensive Cancer Center.

"This is a compelling improvement compared to the 34% PFS observed at six months in the unselected population," said Dr. Deborah Rathjen, Bionomics' CEO and Managing Director.
"These results indicate that moving forward, biomarker-based patient selection has the potential to provide guidance and optimise clinical outcomes in the treatment of renal cancer, presenting a range of new possibilities for BNC105. We will continue to explore further data and the options for the advancement of the compound.

Sorafenib, sunitinib provide no benefit to patients with locally advanced kidney cancer

Findings from a federally funded study suggest that patients with locally advanced kidney cancer should not be treated with either adjuvant (post-surgery) sorafenib or sunitinib. The average period to disease recurrence was similar between those who received sorafenib or sunitinib after surgery (5.6 years) and those treated with placebo (5.7 years). The study will be presented at the upcoming 2015 Genitourinary Cancers Symposium in Orlando.

"These drugs didn't reduce disease recurrence, but on average they did not appear to worsen patient outcomes either," said lead study author Naomi B. Haas, MD, an Associate Professor of Medicine at the Abramson Cancer Center of the University of Pennsylvania in Philadelphia, Pa. "We are still analyzing the various groups of patients enrolled on this trial, and we hope that analysis of patient specimens collected on this study may provide clues into subsets of patients who might still benefit from these therapies."


Treatment reduces risk of recurrence of C. difficile infection

In continuation of my update on metronidazole  &  vancomycin

Among patients with Clostridium difficile infection (CDI) who recovered following standard treatment with the antibiotics metronidazole or vancomycin, oral administration of spores of a strain of C difficilethat does not produce toxins colonized the gastrointestinal tract and significantly reduced CDI recurrence, according to a study in the May 5 issue of JAMA.

C difficile is the cause of one of the most common and deadly health care-associated infections, linked to 29,000 U.S. deaths each year. Rates of CDI remain at unprecedented high levels in U.S. hospitals. Clinical infection also has a recurrence rate of 25 percent to 30 percent among affected patients. Not all strains of C difficile produce toxins. Nontoxigenic C difficile strains that lack the genes for toxin production are also found in the hospital environment and can colonize hospitalized patients, although patients are usually asymptomatic. Gastrointestinal colonization by these nontoxigenic C difficilestrains (in both humans and hamsters) has shown promising results as a potential way to prevent CDI, according to background information in the article.

Dale N. Gerding, M.D., of the Edward Hines Jr. VA Hospital, Hines, Il., and Loyola University Chicago, Maywood, Il., and colleagues randomly assigned 173 adult patients who were diagnosed as having CDI (first episode or first recurrence) to receive 1 of 4 treatments: oral liquid formulation of nontoxigenic C difficile strain M3 (VP20621; NTCD-M3), 104 spores/d for 7 days (n = 43), 107 spores/d for 7 days (n = 44), 107 spores/d for 14 days (n = 42), or placebo for 14 days (n = 44). Prior to enrollment, these patients had all successfully completed treatment with metronidazole, oral vancomycin, or both at 44 study centers in the United States, Canada, and Europe.

Taiho Oncology announces acceptance of TAS-102 NDA for review by FDA


Taiho Oncology, Inc., a subsidiary of Taiho Pharmaceutical Co., Ltd. (Japan), today announced the New Drug Application (NDA) for TAS-102 (nonproprietary names: trifluridine and tipiracil hydrochloride), has been accepted for review by the U.S. Food and Drug Administration (FDA). TAS-102 is an oral combination investigational anticancer drug for the treatment of refractory metastatic colorectal cancer (mCRC).

TAS-102 is an investigational drug candidate for metastatic colorectal cancer. It is a combination of two active pharmaceutical ingredientstrifluridine, (see left structure) Trifluridine structure.svg Tipiracil.svg
a nucleoside analog (see right structure), and tipiracil hydrochloride, a thymidine phosphorylase inhibitor. Tipiracil hydrochloride prevents rapid metabolism of trifluiridine, increasing the bioavailability of trifluiridine.








"The FDA's filing of the TAS-102 NDA represents a significant milestone for our company and underscores the need for new treatment options for patients with refractory metastatic colorectal cancer," said Eric Benn, Taiho Oncology's president and chief executive officer. "Today, we are one step closer to our ultimate goal of gaining regulatory approval for TAS-102 and making it available to patients in the USA with this serious medical condition. We look forward to working closely with the FDA during the NDA review."

Anticoagulant fondaparinux lowers risk of major bleeding events, death in heart attack patients



 Fondaparinux.svg

Patients who experienced a certain type of heart attack who received the anticoagulant fondaparinux had a lower risk of major bleeding events and death both in the hospital and after six months compared to patients who received low-molecular-weight heparin (LMWH), although both groups had similar rates of subsequent heart attack or stroke, according to a study in the February 17 issue of JAMA.

Reducing bleeding events in patients receiving antithrombotic therapy is important since bleeding events are associated with increased mortality. Fondaparinux was associated with reduced major bleeding events and improved survival compared with LMWH (a class of anticoagulant medications) in a large randomized clinical trial involving patients with non-ST-segment elevation myocardial infarction (NSTEMI; a certain pattern on an electrocardiogram following a heart attack). Large-scale experience of the use of fondaparinux vs LMWH outside of a clinical trial setting has been lacking, according to background information in the article.

Karolina Szummer, M.D., Ph.D., of the Karolinska Institutet, Stockholm, Sweden, and colleagues analyzed data from a Swedish registry that included 40,616 patients with NSTEMI who received in-hospital treatment with fondaparinux or LMWH between September 2006 through June 2010, with follow-up through December 2010.

New compound appears to play role in development of opioid tolerance

While opioids are a widely used treatment for pain, patients who take them on a regular basis can become tolerant, requiring a higher dose for continued pain relief. In a study published in Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), researchers identified a compound that appears to play a role in the development of opioid tolerance. It may be possible to lessen the development of opioid tolerance if that compound is neutralized or blocked in patients taking opioids chronically for severe pain.

"Opioid tolerance is a growing problem among chronic pain patients and cancer patients in particular," said Chih-Peng Lin, M.D., assistant professor, Department of Anesthesiology, National Taiwan University College of Medicine. "We found that CXCL1, a protein produced by spinal cord tissue, contributes to opioid tolerance. By neutralizing CXCL1 in patients, we might help solve the problem of opioid tolerance."

Eliglustat drug improves liver, spleen size and hemoglobin level in adults with Gaucher disease type 1






In continuation of my update on eliglustat  



Eliglustat.svg


Among previously untreated adults with Gaucher disease type 1, a genetic disease in which there is improper metabolism due to a defect in an enzyme, treatment with the drug eliglustat resulted in significant improvements in liver and spleen size hemoglobin level, and platelet count, according to a study in the February 17 issue of JAMA.

Gaucher disease type 1 is characterized by enlargement of the spleen and liver, anemia, low blood platelets, chronic bone pain, and the failure to grow properly. Untreated Gaucher disease type 1 is a chronic and progressive disorder associated with disability, reduced life expectancy, and, in some patients, life-threatening complications. The current standard of care is enzyme replacement therapy, which requires lifelong intravenous infusions every other week. A safe, effective oral therapy is needed, according to background information in the article. 

Pramod K. Mistry, M.D., Ph.D., F.R.C.P., of the Yale University School of Medicine, New Haven, Conn., and colleagues randomly assigned 40 untreated adults with Gaucher disease type 1 to receive eliglustat (twice daily; n = 20) or placebo (n = 20) for 9 months. Eliglustat is a novel oral medication, which showed favorable results for patients with this disease in a phase 2 trial. This phase 3 trial was conducted at 18 sites in 12 countries.

The researchers found that administration of eliglustat resulted in a reduction in spleen volume of approximately 30 percent compared with placebo, as well as improvements in hemoglobin level, decreased liver volume (-6.6 percent), and increased platelet count (41 percent). No serious adverse events occurred. No patient discontinued treatment over the course of the 9-month study because of a treatment-emergent adverse event.

New molecule shows promise in controlling HIV without using daily antiretroviral drugs

Scientists have created a new molecule that shows promise for controlling HIV without daily antiretroviral drugs. The molecule foils a wider range of HIV strains in the laboratory than any known broadly neutralizing HIV antibody and is more powerful than some of the most potent of these antibodies. In addition, the molecule safely protected monkeys from infection with an HIV-like virus during a 40-week study period. Together, the data suggest that the molecule could, with further research, be used to subdue HIV in humans. The authors note that the molecule potentially could be used as both a preventative drug and as a treatment. The new findings appear in the February 18 issue of the journal Nature.

"This innovative research holds promise for moving us toward two important goals: achieving long-term protection from HIV infection, and putting HIV into sustained remission in chronically infected people," said Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Eli Lilly accepts committee recommendation to extend evacetrapib Phase 3 trial



Evacetrapib.svg
We know that, Evacetrapib  is a  drug under  development by  Eli Lilly  and  company (investigational   name   LY2484595)      that inhibits cholesterylester transfer protein (CETP), which  transfers and thereby increases high-density lipoprotein and     lowers   low-density lipoprotein. It is thought that modifying lipoprotein levels modifies the    risk     of     cardiovascular   disease.   The  first  CETP inhibitor, torcetrapib, was unsuccessful because it increased levels of the hormone aldosterone and increased blood pressure, which led to excess cardiac events when it was studied.  Evacetrapib does not have the same effect. When studied in a small clinical trial in people with elevated LDL and low HDL, significant improvements were noted in their lipid profile.


A recent report states that,  Eli Lilly and Company (NYSE: LLY) has accepted the recommendation of the ACCELERATE study academic executive committee, based on emerging science in the cardiovascular field, to extend the Phase 3 trial of the investigational medicine evacetrapib by approximately six months. The decision is not based on any data from ACCELERATE, as both the academic committee and the company remain blinded to efficacy results............

Palbociclib extends progression-free survival in advanced breast cancer patients

In continuation of my update on Palbociclib

Palbociclib, an investigational oral medication that works by blocking molecules responsible for cancer cell growth, is well tolerated and extends progression-free survival (PFS) in newly diagnosed, advanced breast cancer patients, including those whose disease has stopped responding to traditional endocrine treatments. Results of the phase II study, led by researchers in the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania , were published this month in Clinical Cancer Research. Earlier phase I results by researchers at Penn Medicine contributed to the development of palbociclib, which was recently approved by the U.S. Food and Drug Administration (FDA) for metastatic breast cancer patients just beginning to undergo endocrine therapy.

"The FDA approval has expanded treatments options for many metastatic breast cancer patients, but these new results are showing how effective the drug can also be for breast cancer patients who have already tried endocrine therapies and may be running out of options," said lead investigator Angela DeMichele, MD, MSCE , associate professor in the division of Hematology/Oncology and Epidemiology and co-leader of the Breast Cancer Research Program at the Abramson Cancer Center. "Combined with the promising results from other trials looking at the effectiveness of this drug, our results indicate that palbociclib can extend the duration of disease control and produce tumor shrinkage in patients with estrogen-receptor positive (ER+) breast cancer, without the debilitating side effects of chemotherapy."
The newly-published phase II trial primarily sought to evaluate disease response and control, while monitoring for the presence of side effects such as neutropenia, an abnormally low white blood cell count. Patients enrolled in the trial had previously undergone several prior chemotherapy and hormonal regimens for metastatic disease. Palboclib was administered once daily for 21 days each month.

Overall, researchers noted a median PFS, the time before a tumor worsens or the patient dies, of 3.7 months for patients taking the drug. However, patients with hormone receptor-positive (HR+) breast cancer -where the breast cancer cells depend on the hormones estrogen and progesterone to grow - had significantly longer PFS (5.1 months) compared to that of the HR-negative group (84 percent and 11 percent of the enrolled population, respectively). And those who had previously progressed through at least two rounds of hormonal therapy saw significantly greater benefits, suggesting substantial activity in the setting of acquired endocrine resistance.

Mayo Clinic researchers identify molecule that lays groundwork for development of pancreatic cancer

A research team led by investigators from Mayo Clinic's campus in Jacksonville, Florida, and the University of Oslo, Norway, have identified a molecule that pushes normal pancreatic cells to transform their shape, laying the groundwork for development of pancreatic cancer -- one of the most difficult tumors to treat.

Their findings, reported in Nature Communications, suggest that inhibiting the gene, protein kinase D1 (PKD1), and its protein could halt progression and spread of this form of pancreatic cancer, and possibly even reverse the transformation.

"As soon as pancreatic cancer develops, it begins to spread, and PKD1 is key to both processes. Given this finding, we are busy developing a PKD1 inhibitor that we can test further," says the study's co-lead investigator, Peter Storz, Ph.D., a cancer researcher at Mayo Clinic.

Lenvatinib trial offers hope for thyroid cancer patients


Lenvatinib skeletal.svg
A new targeted therapy called lenvatinib has been shown to improve progression-free survival among patients with advanced thyroid cancer that is not responsive to iodine-131.

In a clinical trial of almost 400 patients from 21 different countries, patients who took lenvatinib survived for a median of 18.3 months without displaying any signs of disease progression, while those who were given placebo only had a median progression-free survival of 3.6 months.

"The median progression-free survival in the placebo group in this study was shorter than the 8 months expected, indicating that these patients had aggressive thyroid cancer," write the authors of the study, which was published in the New England Journal of Medicine.

Given the results of this trial, lenvatinib may become the standard treatment for patients resistant to idoine-131, says lead author Martin Schlumberger from the Department of Nuclear Medicine and Endocrine Oncology at Gustave Roussy in France.

New antibody shows promise in increasing survival for patients suffering from influenza, pneumonia



Figure thumbnail fx1



Scientists from NTU Singapore, the world's No. 1 young university, have developed an antibody which boosts the survival chances for patients suffering from influenza and pneumonia.

Proven effective in lab tests, the antibody is now being made suitable for use in humans. The scientists are also using the new antibody to develop a diagnostic kit which can help doctors accurately track the recovery progress of flu and pneumonia patients.

The patent-pending antibody has generated much interest globally. Two biotech multi-national corporations, Abcam based in the United Kingdom and Adipogen International based in the United States, have won the rights to license the antibody. The two multinational companies will produce the antibody for sale to global organisations doing research in vaccine and drug development.

The breakthrough finding was published in the latest issue of the prestigious international peer-reviewed journal Cell Reports.

Eisai announces FDA approval of LENVIMA (lenvatinib) for treatment of RAI-refractory DTC



Lenvatinib skeletal.svg

Eisai Inc. announced today that the U.S. Food and Drug Administration (FDA) approved the company's receptor tyrosine kinase inhibitor LENVIMA™ (lenvatinib) for the treatment of locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer (RAI-R DTC). LENVIMA was approved following a priority review by the FDA, which is designated for drugs the FDA believes have the potential to provide a significant improvement in the treatment of a serious condition. LENVIMA demonstrated a statistically significant progression-free survival (PFS) prolongation and response rate in patients with progressive, differentiated thyroid cancer who had become refractory to radioactive iodine (RAI) therapy.

"In the pivotal Phase 3 SELECT clinical trial, recently published in the New England Journal of Medicine, treatment with LENVIMA resulted in a highly statistically significant improvement in progression-free survival and a high overall response rate in patients with locally recurrent or metastatic, progressive, RAI-refractory DTC," said Lori J. Wirth, M.D., study investigator and medical director of the Center for Head and Neck Cancers at the Massachusetts General Hospital. "The thyroid cancer community welcomes an agent that offers a significant, effective option for the treatment of differentiated thyroid cancer in patients who have progressed after becoming refractory to RAI therapy."

Study identifies BLU-554 as potential treatment option for HCC patients

Findings were presented today at The International Liver CongressTM 2015 on a novel therapeutic candidate for a genomically defined subset of hepatocellular carcinoma (HCC) patients with an aberrant fibroblast growth factor receptor 4 (FGFR4) pathway. BLU-554, a small molecule inhibitor of FGFR4, has been identified as a potential treatment option for up to 30% of HCC patients. In preclinical studies, the investigational drug was shown to be potent and 'exquisitely selective' for FGFR4 compared to other kinases targeting the FGFR family.

Overexpression of fibroblast growth factor 19 (FGF19), the ligand for FGFR4, can promote liver tumour formation (as observed in genetically-engineered mice), a process that can be blocked by knocking out the FGFR4 gene. This suggests that FGFR4 inhibition might be an effective treatment strategy in HCC patients whose tumours have an active FGF19/FGFR4 signalling axis.

Omega-3 could supplement anti-VEGF treatment in AMD

In continuation of my update on Omega 3 fatty acid

Pilot study findings suggest that taking omega-3 fatty acid supplements could increase the efficacy or reduce the needed frequency of anti-vascular endothelial growth factor(VEGF) treatment in patients with exudative age-related macular degeneration (AMD).

Researcher Flavio Rezende (University of Montreal, Quebec, Canada) and co-workers say that 5–10% of patients with wet AMD lose three lines or more of visual acuity, despite treatment, and that more frequent anti-VEGF injections are associated with side effects.

An extra protein gives naked mole rats more power to stop cancer

A protein newly found in the naked mole rat may help explain its unique ability to ward off cancer. The protein is associated with a locus that is also found in humans and mice. It's the job of that locus to encode several cancer-fighting proteins. The locus found in naked mole rats encodes a total of four cancer-fighting proteins, while the human and mouse version encodes only three.
