It is estimated that 366 million people had Diabetes Mellitus in 2011; by 2030 this would have risen to 552 million. Many oral hypoglycaemic agents are…
Otsuka Receives Complete Response Letter From U.S. Food And Drug Administration For Tolvaptan For Use In Patients With Autosomal Dominant Polycystic Kidney Disease
Otsuka Pharmaceutical Submits New Drug Application in Japan for Tolvaptan for the Treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD)
may 30 2013
- Tolvaptan was discovered by Otsuka in Japan, and its primary results from a global clinical trial involving 1,400 ADPKD patients from 15 countries, which demonstrated a statistically significant reduction in the rate of total kidney volume, were published in New England Journal of Medicine in 2012. It is also currently under a fast track review in the US, following our announcement of FDA accepting to review the application in April 2013.
- ADPKD is a hereditary and often physically and mentally burdensome disease characterized by the development of multiple cysts in the kidneys. ADPKD is often associated with pain, hypertension, decreased kidney function and ultimately, kidney failure that may result in hemodialysis or kidney transplantation.
- There are estimated to be approximately 31,000 ADPKD patients in Japan, and the diagnosed prevalence is estimated to be between 1:1000 and 1:4000 globally.
(Tokyo, Japan, May 30, 2013) – Otsuka Pharmaceutical Co., Ltd. Today announced it filed an application with the Pharmaceutical and Medical Devices Agency in Japan (PMDA) to market its novel compound tolvaptan for the treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD). Phase III clinical trial results that form the basis of the regulatory filing were published in the New England Journal of Medicine in November 2012. The MHLW has designated tolvaptan as an Orphan Drug.http://www.otsuka.co.jp/en/release/2013/0603_02.html
Tolvaptan (INN), also known as OPC-41061, is a selective, competitive vasopressin receptor 2 antagonist used to treat hyponatremia (low blood sodium levels) associated withcongestive heart failure, cirrhosis, 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 Tolvat & Tolsama.
Tolvaptan is also in fast-track clinical trials for polycystic kidney disease. In a 2004 trial, tolvaptan, when administered with traditional diuretics, was noted to increase excretion of excess fluids and improve blood sodium levels in patients with heart failure without producing side effects such as hypotension (low blood pressure) or hypokalemia(decreased blood levels of potassium) and without having an adverse effect on kidney function. In a recently published trial (TEMPO 3:4 ClinicalTrials.gov number, NCT00428948) the study met its primary and secondary end points. Tolvaptan, when given at an average dose of 95 mg per day over a 3-year period, slowed the usual increase in kidney volume by 50% compared to placebo (2.80% per year versus 5.51% per year, respectively, p<0.001) and reduced the decline in kidney function when compared with that of placebo-treated patients by approximately 30% (reciprocal serum creatinine, -2.61 versus -3.81 (mg/mL)-1 per year, p <0.001)

WHIPPANY, N.J. and SOUTH SAN FRANCISCO, Calif., Aug. 30, 2013 /PRNewswire/ — Bayer HealthCare and Onyx Pharmaceuticals, Inc. (NASDAQ: ONXX) announced today that the European Commission has approved Stivarga® (regorafenib) tablets for the treatment of adult patients with metastatic colorectal cancer (mCRC).
In September 2012, Stivarga was approved by the U.S. Food and Drug Administration (FDA) for the treatment of patients with mCRC who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if KRAS wild type, an anti-EGFR therapy.
OLD ARTICLE PASTED
February 25, 2013 — The U.S. Food and Drug Administration today expanded the approved use of Stivarga (regorafenib) to treat patients with advanced gastrointestinal stromal tumors (GIST) that cannot be surgically removed and no longer respond to other FDA-approved treatments for this disease.
GIST is a tumor in which cancerous cells form in the tissues of the gastrointestinal tract, part of the body’s digestive system. According to the National Cancer Institute, an estimated 3,300 to 6,000 new cases of GIST occur yearly in the United States, most often in older adults.
Stivarga, a multi-kinase inhibitor, blocks several enzymes that promote cancer growth. With this new approval, Stivarga is intended to be used in patients whose GIST cancer cannot be removed by surgery or has spread to other parts of the body (metastatic) and is no longer responding to Gleevec (imatinib) and Sutent (sunitinib), two other FDA-approved drugs to treat GIST.
“Stivarga is the third drug approved by the FDA to treat gastrointestinal stromal tumors,” said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “It provides an important new treatment option for patients with GIST in which other approved drugs are no longer effective.”
Stivarga was approved in September 2012 to treat colorectal cancer. It is marketed by Bayer HealthCare Pharmaceuticals, based in Wayne, N.J. Gleevec is marketed by East Hanover, N.J.-based Novartis, and Sutent is marketed by New York City-based Pfizer.
Regorafenib (BAY 73-4506, commercial name Stivarga) is an oral multi-kinase inhibitor developed by Bayer which targets angiogenic, stromal and oncogenic receptor tyrosine kinase (RTK). Regorafenib shows anti-angiogenic activity due to its dual targetedVEGFR2-TIE2 tyrosine kinase inhibition. It is currently being studied as a potential treatment option in multiple tumor types.
Metastatic colorectal cancer
Regorafenib demonstrated to increase the overall survival of patients with metastaticcolorectal cancer and has been approved by the US FDA on September 27, 2012.Stivarga is being approved with a Boxed Warning alerting patients and health care professionals that severe and fatal liver toxicity occurred in patients treated with Stivarga during clinical studies. The most common side effects reported in patients treated with Stivarga include weakness or fatigue, loss of appetite, hand-foot syndrome (also called palmar-plantar erythrodysesthesia), diarrhea, mouth sores (mucositis), weight loss, infection, high blood pressure, and changes in voice volume or quality (dysphonia).

The hopes and perils of betting on cancer treatments
NEW weapons are emerging in the war on cancer. That is good news not just for patients but also for drug companies. The biggest ones, faced with falling sales as their existing medicines go off-patent, are investing in smaller firms with promising cancer treatments under development, hoping to secure the next blockbuster.

Pharmacyclics is getting a priority review of its blood cancer treatment by federal regulators. A priority review shortens a drug evaluation by the U.S. Food and Drug Administration from 10 months to six. The acceptance of the application triggers a $75 million milestone payment to Pharmacyclics from Johnson & Johnson’s Janssen unit.
Ibrutinib (USAN), also known as PCI-32765, is an experimental drug candidate for the treatment of various types of cancer. It is an orally-administered, selective and covalent inhibitor of the enzyme Bruton tyrosine kinase (Btk). Ibrutinib is currently under development by Pharmacyclics, Inc and Johnson & Johnson’s Janssen Pharmaceutical division for B-cell malignancies including chronic lymphocytic leukemia, mantle cell lymphoma, diffuse large B-cell lymphoma, and multiple myeloma.. Ibrutinib was first designed and synthesized at Celera Genomics by Zhengying Pan, who along with a team of chemists and biologists reported in 2007 a structure-based approach for creating a series of small molecules that inactivate BTK through covalent binding to cysteine-481 near the ATP binding domain of BTK. These small molecules irreversibly inhibited BTK by using a Michael acceptor for binding to the target cysteine. In April 2006, Pharmacyclics acquired Celera’s small molecule BTK inhibitor discovery program, which included a compound, PCI-32765 (known as compound 13 in the Pan et al paper) that was subsequently chosen for further preclinical development based on the discovery of anti-lymphoma properties in vivo . Since 2006, Pharmacyclics’ scientists have advanced the molecule into clinical trials and identified specific clinical indications for the drug.    It also has potential effects against autoimmune arthritis.
It has given good results in two phase II clinical trials.
In preclinical studies on chronic lymphocytic leukemia (CLL) cells, ibrutinib has been reported to promote apoptosis, inhibit proliferation, and also prevent CLL cells from responding to survival stimuli provided by the microenvironment. In this study, treatment of activated CLL cells with ibrutinib resulted in inhibition of Btk tyrosine phosphorylation and also effectively abrogated downstream survival pathways activated by this kinase including ERK1/2, PI3K, and NF-κB. Additionally, ibrutinib inhibited proliferation of CLL cells in vitro, effectively blocking survival signals provided externally to CLL cells from the microenvironment including soluble factors (CD40L, BAFF, IL-6, IL-4, and TNF-α), fibronectin engagement and stromal cell contact.
In early clinical studies, the activity of ibrutinib has been described to include a rapid reduction in lymphadenopathy accompanied by a transient lymphocytosis, suggesting that the drug might have direct effects on cell homing or migration to factors in tissue microenvironments.
Ibrutinib has been reported to reduce CLL cell chemotaxis towards the chemokines CXCL12 and CXCL13, and inhibit cellular adhesion following stimulation at the B cell receptor. Together, these data are consistent with a mechanistic model whereby ibrutinib blocks BCR signaling, which drives cells into apoptosis and/or disrupts cell migration and adherence to protective tumor microenvironments.

It acts via decreasing synthesis of aqueous humor, and increasing the amount that drains from the eye through uveoscleral outflow. As a treatment for glaucoma, it is usually given in eyedrop form.
Mechanism of action
Peripheral alpha 2 agonist activity results in vasoconstriction of blood vessels (as opposed to central alpha 2 agonist activity that decreases sympathetic tone, as can be seen by the medication clonidine). This vasoconstriction may explain the acute reduction in aqueous humor flow. The increased uveoscleral outflow from prolonged use may be explained by increased prostaglandin release due to alpha adrenergic stimulation. This may lead to relaxed ciliary muscle and increased uveoscleral outflow.
In 2013, the FDA approved topical application of brimonidine 0.33% (Mirvaso) for facial erythema or rosacea.

The Portuguese Government spends almost as much money on the NHS hospitals’ expenses with medicines as with the reimbursement of all drugs sold in pharmacies, according to data revealed by the Portuguese Ministry of Health.
The numbers disclosed show that, in 2012, the state spent about $ 2,200 million with drugs, 1.200 million of which with the reimbursement of medicines sold in pharmacies and 1.000 million with medicines provided in hospitals.
While the expenses on drugs sold in pharmacies are in control, thanks to successive price cuts by the Government over the years – just in 2013, about 1.400 brand drugs had mandatory a 7% price discount – the expenses with medicines in hospitals and debts to the Pharmaceutical Industry grew again this year, both in value and in average payments. This upward trend is ongoing for six consecutive months.
In July, the value…
