India-based Cipla has introduced Serroflo (salmeterol/fluticasone MDI) in Germany and Sweden to treat patients suffering from asthma.
Serroflo is expected to improve the affordability of fixed combinations in Europe and help manage health costs for respiratory treatment.
Cipla Europe head Frank Pieters said: “With Serroflo, we offer in Germany and Sweden an alternative, which is effective and efficient and therefore brings many advantages into a market, which suffers from limited resources.”
The new product is available under the name Serroflo in Germany, while it is introduced as Salmeterol/Fluticasone Cipla in Sweden.
Cipla’s shares have vaulted to a record high after the launch of first of its combination inhalers in Germany and Sweden that marked its entry into Europe. Analysts say the launch will lead to a gradual rerating of the stock of the drug maker which has been underperforming its peers.
Indian pharma company, Lupin Limited announced a strategic distribution agreement with LG Life Sciences of South Korea to launch Insulin Glargine, a novel insulin analogue under the brand name Basugine™.
According to the agreement, Lupin would be responsible for marketing and sales of Basugine™ in India.
Indian generics major Cipla has unveiled plans to invest £100 million in the UK as it looks to expand its global footprint.
The deal was announced by Chancellor of the Exchequer George Osborne (pictured) who is on a trade mission to India, stating that the investment will fund the launch of a range of drugs in the areas of respiratory, oncology and antiretroviral medicines. He added that the cash will also be used on R&D, clinical trials “and further expansion internationally and in the UK”.
GMP deviations and even data falsification have been identified in a number of companies in India. How is it possible that interpretation of FDA and EU authorities on one side and the Indian authority on the other side come to a completely different picture? Read more in our GMP News
GMP deviations and even data falsification have been identified in a number of companies in India. The FDA has issued numerous Warning Letters, the EU has published GMP Non Compliance Reports in its EudraGMDP database and EDQM has withdrawn various CEPs because of GMP inspection findings.
In an article published by Regulatory Focus on 28 January 2014 the question has been raised whether Indian companies have a chronic data falsification problem. The article lists 7 companies in India which have received a Warning Letter in the past months – all of them because of GMP deviations and because of “actually or potentially tampering with their data”. In addition to the 7 companies the Ranbaxy case is a story of its own. Not only one facility was found to manipulate data but several sites of the company are involved. For this reason the US FDA has issued a consent decree of permanent injunction against Ranbaxy. All manufactured products in the facilities concerned are now subject to an FDA import alert. In a press release the FDA states: “Because this company continued to violate current good manufacturing practice regulations and falsify information on drug applications, the FDA took these actions in an effort to protect consumers.” Dara Corrigan, FDA associate commissioner for regulatory affairs goes on: “The FDA continues to be committed to protecting consumers from potentially unsafe products that may be offered on the market.” On January 23, 2014 the FDA added an additional facility of Ranbaxy to the existing consent decree.
So far, the Indian Authority did not initiate the same measures like US and European counterparts. This also questions the supervision system in India. If inspections have been performed by Indian Inspectors at the concerned facilities why did they fail to make the same findings? The Drug Controller General of India, Mr. G.N. Singh, gave an interesting interpretation: According to an interview published by live mint & Wall Street Journal he said: “…it must be stated that every country has different measures and we cannot judge Ranbaxy by standards set up by the American drug regulator“. When Mr Singh was asked about the problems identified at three Ranbaxy plants he stated: “Some of those were found to be true and my office had told Ranbaxy to take corrective measures. Similar procedures will be followed in this case as well. But I do not think this is a situation which will warrant withdrawal of drugs from the domestic market. Our biggest objective is to maintain good quality of medicines and we are doing that. There are no drugs in the Indian market that are not up to the standards stated under the Drugs and Cosmetics Act.” In a final statement in the interview he also mentioned that he is “not worried about issues of quality.” In another interview with the Business Standard Press Mr Singh made an alarming statement for all customers of medicinal products and APIs in Europe and the US. “If I follow US standards, I will have to shut almost all drug facilities“. If this is the truth EU and US customers are in big trouble because products not complying to EU/US GMP standard (e.g. ICH Q7 GMP for APIs) would need to be taken from the market immediately.
This all looks like it will not fit together. How is it possible that interpretation of FDA and EU authorities on one side and the Indian authority on the other side come to a completely different picture? It can only mean that dual standards exist. This would result in two quality levels, an international and a domestic quality level. Such a policy possibly causes questions by Indian patients who have to accept a different and probably lower quality standard.
But what are the international implications of this strategy? European Regulators need to react as they require from the Indian Authority to issue Written Confirmations of GMP compliance. Without a Written Confirmation APIs can not enter EU market. Currently more than 200 Written Confirmations have been issued by Indian Authority. If the inspections which have been performed as a prerequisite for issuing a Written confirmation were not based on the international standard ICH Q7 (GMP for APIs) the Written Confirmations are no longer valid documents. This issue might be raised by an EU court if a substandard API in a medicinal product will cause a health risk to patients in Europe.
My new tenure at FDA began in June, but as a former health attaché in the U.S. Embassy, I played an enthusiastic role in helping to establish FDA in my native country. I was born in Kashmir, India, and though I left the country in 1980 to explore new professional opportunities in the United States, I have since been drawn back again and again.
Halaven is a novel anticancer agent discovered and developed in-house by Eisai and is currently approved in more than 50 countries, including Japan, the United States and in Europe. In Russia, Halaven was approved in July 2012 for the treatment of locally advanced or metastatic breast cancer previously treated with at least two chemotherapy regimens including an anthracycline and a taxane. Approximately 50,000 women in Russia are newly diagnosed with breast cancer each year, with this type of cancer being the leading cause of death in women aged 45 to 55 years. read all at…………………….
Eribulin mesylate (Halaven; Eisai) — a synthetic analogue of the marine natural product halichondrin B that interferes with microtubule dynamics — was approved in November 2010 by the US Food and Drug Administration for the treatment of metastatic breast cancer.
Family members of the product patent, WO9965894, have SPC protection in the EU until 2024 and one of its Orange Book listed filings, US8097648, has US154 extension till January 2021.
The drug also has NCE exclusivity till November 2015.
Halichondrin B, a large polyether macrolide, was isolated 25 years ago from the marine sponge Halichondria okadai
Eribulin is an anticancer drug marketed by Eisai Co. under the trade name Halaven. Eribulin mesylate was approved by the U.S. Food and Drug Administration on November 15, 2010, to treat patients with metastatic breast cancer who have received at least two prior chemotherapy regimens for late-stage disease, including both anthracycline– and taxane-based chemotherapies.[1] It was approved by Health Canada on December 14, 2011 for treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. [2]
Eribulin has been previously known as E7389 and ER-086526, and also carries the US NCI designation NSC-707389.
Eribulin mesylate is an analogue of halichondrin B, which in 1986 was isolated from the marine sponge Halichondria okadai toxic Pacific.Halichondrin B has a significant anti-tumor activity. The Eribulin synthetically obtained has a simpler but still complex molecular structure.Taxanes such as to inhibit the spindle apparatus of the cell, but it is engaged in other ways.
The substance inhibits the polymerization of tubulin into microtubules and encapsulates tubulin molecules in non-productive aggregates from. The lack of training of the spindle apparatus blocks the mitosis and ultimately induces apoptosis of the cell. Eribulin differs from known microtubule inhibitors such as taxanes and vinca alkaloids by the binding site on microtubules, also it does not affect the shortening. This explains the effectiveness of the new cytostatic agent in taxane-resistant tumor cell lines with specific tubulin mutations.
Structure and mechanism
Structurally, eribulin is a fully synthetic macrocyclic ketone analogue of the marine sponge natural product halichondrin B,[4][5] the latter being a potent naturally-occurring mitotic inhibitor with a unique mechanism of action found in the Halichondria genus of sponges.[6][7] Eribulin is a mechanistically-unique inhibitor of microtubule dynamics,[8][9] binding predominantly to a small number of high affinity sites at the plus ends of existing microtubules.[10] Eribulin exerts its anticancer effects by triggering apoptosis of cancer cells following prolonged and irreversible mitotic blockade.[11][12]
A new synthetic route to E7389 was published in 2009.[13]

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.
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.
New Delhi: Officials in the Indian health ministry have admitted that about 26 new drug molecules were given approval since 2010 without conducting any proper clinical trials on local population to test their safety and efficacy. Despite strict instructions by the parliamentary standing committee on health, so many new drugs have continued to make their way into the market.
