Otsuka Pharmaceutical Submits New Drug Application in Japan for Tolvaptan for the Treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD)

JUNE 10, 2013 3:46 AM

TOLVAPTAN

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 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 Tolvat & Tolsama.

Tolvaptan is also in fast-track clinical trials[2] 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.[3] 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)[4]

Bayer’s Stivarga® (regorafenib) Tablets Approved in Europe

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.

Regorafenib

cas 755037-03-7

4-[4-({[4-Chloro-3-(trifluoromethyl)phenyl]carbamoyl}amino)-3-fluorophenoxy]-N-methylpyridine-2-carboxamide hydrate

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.[1]

Metastatic colorectal cancer

Regorafenib demonstrated to increase the overall survival of patients with metastaticcolorectal cancer[2] and has been approved by the US FDA on September 27, 2012.[3]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).[4]

FDA grants priority review to Pharmacyclics drug

ibrutinib

FDA grants priority review to Pharmacyclics drug

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[1]), 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).[2][3][4] 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.[6][7][8]. 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[2]. 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 [5]. Since 2006, Pharmacyclics’ scientists have advanced the molecule into clinical trials and identified specific clinical indications for the drug. [2][3][4] [5] [6][7][8] It also has potential effects against autoimmune arthritis.[9]

Clinical trials

It has given good results in two phase II clinical trials.[10]

Mechanism

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.[11] 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.[12]

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.[13][14] 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.

Bergamottin is a natural furanocoumarin found principally in grapefruit juice. It is also found in the oil of bergamot orange, from which it was first isolated and from which its name is derived. To a lesser extent, bergamottin is also present in the essential oils of other citrus fruits. Along with the chemically related compound 6′,7′-dihydroxybergamottin, it is believed to be responsible for thegrapefruit juice effect in which the consumption of the juice affects the metabolism of a variety of pharmaceutical drugs.[1]

Chemistry

Chemically, bergamottin and dihydroxybergamottin are linear furanocoumarins functionalized with side chains derived fromgeraniol. They are inhibitors of some isoforms of the cytochrome P450 enzyme, particularly CYP3A4.[2] This prevents oxidative metabolism of certain drugs by the enzyme, resulting in an elevated concentration of drug in the bloodstream.

Normally, the grapefruit juice effect is considered to be a negative interaction, and patients are often warned not to consume grapefruit or its juice when taking medication. However, some current research is focused on the potential benefits of cytochrome P450 inhibition.[3] Bergamottin, dihydroxybergamottin, or synthetic analogs may be developed as drugs that are targeted to increase the oral bioavailability of other drugs. Drugs that may have limited use because they are metabolized by CYP3A4 may become viable medications when taken with a CYP3A4 inhibitor because the dose required to achieve a necessary concentration in the blood would be lowered.[4]

Biosynthesis of bergamottin

Bergamottin is derived from components originating in the shikimate pathway.[5] The biosynthesis of this compound starts with the formation of the demethylsuberosin (3) product which is formed via the alkylation of the umbelliferone (2) compound.[6] The alkylation of the umbelliferone is initiated with the use of dimethylallyl pyrophosphate, more commonly known as DMAPP. The cyclization of an alkyl group occurs to form marmesin (4), which is done in the presence of NADPH and oxygen along with a cytochrome P450 monooxygenase catalyst.[7] This process is then repeated twice more, first to remove the hydroxyisopropyl substituent from marmesin (4) to form psoralen (5), and then to add a hydroxyl group to form bergaptol (6).[8] Bergaptol (6) is next methylated with SAM, S-Adenosyl methionine, to form bergapten (7). The final step in this biosynthesis is the attachment of a GPP, or geranyl pyrophosphate, to the newly methylated bergapten (7) to form the target molecule bergamottin (8).

Transform your life in 10 minutes with ancient ‘youthing’ practice

life

NaturalNews) If you need more zest and zip in your life, the secret to these states and more can be found in a set of simple (yet profound) yogic exercises known as the “Five Tibetans.” Developed by Buddhist monks and brought to the West in the 1930s, Tibetan yoga is a series of five movements that improve digestion and circulation while dispelling fatigue and depression. Advocates of the practice rave about the boundless energy, clarity and vitality the short daily sessions produce. And many also believe Tibetan yoga reverses the hands of time, promoting an ageless and disease free body.

RESEARCH CENTRE AT MAHAPE INDIA

Glenmark Pharma – The persevering innovator

Glenn Saldanha, chairman, Glenmark Pharmaceuticals Ltd

Every Tuesday, unmindful of the gridlocked traffic, Glenn Saldanha, the 43-year-old Chairman of Glenmark Pharmaceuticals Ltd, or GPL, makes it a point to visit his research centre at Mahape in Navi Mumbai. It is the hub of Glenmark’s focus on creating new chemical entities, or NCEs, R&Dspeak for original drugs. Leading the innovation for Saldanha are his lab coat-clad scientists and researchers peering into the test tubes, burettes and pipettes at the Mahape facility.

“Almost 30 to 40 per cent of my time spent on business goes into issues relating to innovation,” he says. That includes thinking about research strategy, deciding on which chemical targets to focus on and which therapeutic segments to chase, and even hiring key R&D talent. Today, out of Glenmark’s 600-odd scientists, 400 are involved in NCE research.

The past 13 years have convinced the ardent admirer of Steve Jobs, the iconic former CEO of Apple, that the future lies in innovation. “If you look at how some of the largest corporations of the world were built, it is clear you need to have innovative products,” says Saldanha, a pharmacist by training, who voraciously reads scientific journals to stay updated on current scientific thought and trends. “Look at what Apple has created… that is the way to build a mega corporation, and that is the key reason why, despite our setbacks, we believe so heavily in innovation.”

Creating an NCE has been the Holy Grail for Indian pharma companies, including giants such as Dr Reddy’s Laboratories and Ranbaxy Laboratories (now owned by Daiichi Sankyo of Japan), but without any major success so far. These companies have reviewed their focus on NCE research and some branched into related activities like differentiated products. So has Glenmark, but it also soldiers on with drug discovery as its key focus area. With five molecules currently undergoing trials in various phases, the company now leads the charge of the Indian drug research industry.

Even one successful launch, say that of revamilast (for asthma and rheumatoid arthritis), which has potential peak sales of $2 billion worldwide, could change the fortunes of the company, though one can never be sure till it actually happens. Next year, Glenmark is likely to have half a dozen compounds in Phase II human trials. Saldanha hopes to hit the market with one or more of his drugs between 2015 and 2017. This potential upside is precisely why Glenmark is in this listing of Tomorrow’s Goliaths, and not any of the other bigger or faster-growing companies.

Undiminished zest
“Every year we expect two more molecules to get into clinical trials,” says Saldanha, his zest undiminished by past failures. “In 2008, in a span of one or two quarters, our entire pipeline pretty much got wiped out, but we never lost our commitment and passion.” At that time its most advanced molecule, oglemilast, used for treating patients with chronic obstructive pulmonary disease, had to be abandoned when its Phase IIb trials produced unsatisfactory results. It also had to suspend clinical development of GRC 6211, a compound for treating osteoarthritis pain, because of side effects.

Unlike other companies that reduced NCE development efforts when faced with similar situations, Glenmark persevered. “We never downsized our research team and did not cut back on budgets,” says Saldanha. “We did not even cut travel and our scientists continued to participate in major global conferences.” It is hardly surprising that his core R&D team has stayed put. Consider Neelima Joshi, 48, Senior Vice President and Head of NCE R&D, who was part of the dozen-odd people who set up the Mahape facility in 2000.

Even then, she says, Glenmark’s management was clearly focused on innovation and the move was in anticipation of the product patent regime that was to come in 2005. It was the impending change in India’s patent law that shaped the mind of the 29-year-old Saldanha in 1998, when he returned to India after working with Eli Lilly and PricewaterhouseCoopers to run his father Gracias Saldanha’s formulations business. After India became a signatory to General Agreement on Tariffs and Trade, it changed its patent law in 2005 from a process patent, which encouraged creation of copies of blockbuster original drugs with minor process changes, to a product patent, where the original drug’s patent itself is recognised in India, thereby prohibiting the creation of copies. This key change, and Saldanha’s passion for research, convinced him to steer Glenmark the NCE way.

However, not everyone agrees with Glenmark’s approach to NCE development, especially of giving away a promising molecule in the early stages to big multinational companies for further R&D. The argument: outlicensing a molecule at a later stage can give a company better valuations. The alternative is to do what Piramal Healthcare wants to – not outlicense. “We believe in taking the drug from the bench to market,” says Dr Swati A. Piramal, Vice Chairperson of Piramal Healthcare, which hopes to deploy the funds it got from sale of its formulations business to Abbott for its R&D efforts. “We are now at the end of the 10 years, having begun in 2002, and we hope between 2012 and 2015, we will hit the market with a new drug.”

While Piramal’s approach is a bench-to-market one, others such as Sun Pharma have developed a different model. Sun Pharma has created a separate research entity called Sun Pharma Advanced Research Centre, better known as SPARC, whose sustainability is built by making differentiated and innovative “generic-plus” products (in simple language, the risk is less, as the basic ingredient is known, but the company is developing a patented technology and a better-targeted product with intellectual property built in). What is more, the returns from this are to help fund the research programme.

On the other hand, Hyderabadbased Dr Reddy’s, one of the pioneers of India’s drug discovery journey, has today rationalised its research programme. It had, in fact, tried out a unique model of creating the country’s first integrated drug development company, Perlecan Pharma, which had equity capital commitments from ICICI Venture and other investors. But it soon saw the outside investors exit and brought back Perlecan into the Dr Reddy’s fold after delays in progress of candidates were not acceptable to some partners who had wanted early monetisation.

Beyond NCEs
Dr Reddy’s has now widened its scope beyond NCEs to differentiated products and formulations where improvements are made on existing products that have limited competition in the market. Its only Phase III candidate, balaglitazone, a diabetes drug, has yet to deliver the goods; the asset class it belongs to, glitazone, has had to deal with an overhang of safety concerns, especially in cases where there is a prolonged use of the drug. Yet, Dr Reddy’s sees sense in Glenmark’s model. “It is a viable model and a right strategy for a small company as Indian companies do not have the capacity to take the drug on their own to the market,” says Satish Reddy, Chief Operating Officer and Managing Director of Dr Reddy’s. “They will need to depend on upfront and milestone payments, and royalties.”

Analysts are cautiously optimistic as Glenmark will have some six compounds in Phase II only next year. Plus the fact that Glenmark has still not hit the market with a new drug weighs it down. “It has had no material success so far; they may make it big but it is difficult to say right now,” says a Mumbai-based analyst.

Neelima Joshi Senior VP and Head, NCE R&D
Even in 2000, our management was clearly focused on innovation and the move was in anticipation of the product patent regime that was to come: Neelima Joshi

On his part, Saldanha argues that he has already recovered his R&D investments. “Till date, we have spent about $120 million in innovation research; against that we have got around $200 million as upfront and milestone payments.”

Says Nomura Financial Advisory and Securities in a recent report: “Glenmark has generated outlicensing income every year from 2004/05 to 2011/12 – except 2008/09. Average licensing income has been Rs 1 billion over the eightyear period. With seven development assets in the pipeline, we believe Glenmark will be able to continue to book licensing income, although the quantum and timing cannot be predicted.”

With standalone revenues of Rs 1,154.63 crore and consolidated revenues of almost Rs 3,000 crore, Glenmark hopes to hit the $1-billion mark soon. And if one of the NCEs sails through, the impact on the topline will be significant – a huge distance travelled for a company that clocked less than Rs 100 crore in the late 1990s. Certainly, Saldanha’s long drives on the Mumbai roads to his R&D headquarters are proving worthwhile.

MY, DR AMC  COMMENTS- BIOCON GREAT PERFORMANCE, U ARE EVERYWHERE

 

Kiran Mazumdar Shaw: We have focused on creating key growth drivers and have structured the company along those growth drivers. These growth drivers are beginning to deliver very strongly for us.

The first is our small molecule business vertical, which is about our historic statins and immunosuppressant’s API business. This particular vertical going forward is envisioned to go up the value chain along an ANDA path and we believe that will improve the quality of earnings in this particular vertical, which for a long time was under pressure because of commoditisation of statins.http://economictimes.indiatimes.com/opinion/interviews/small-molecule-api-biz-to-be-growth-drivers-for-company-kiran-mazumdar-shaw-biocon/articleshow/21975113.cms
