Focus On Patient Compliance To Boost Pharma Sales…And More…

Posted on by

One high-impact area in the healthcare space that often finds its place in the backseat is – patient noncompliance. A term that is commonly used in regard to ‘a patient who does not take a prescribed medication or follow a prescribed course of treatment.’ It comes with a steep price, for causing serious adverse impact not just on human health and health system, but also in the pharma business. Intriguingly, such incidents are still not scientifically monitored enough and vigorously acted upon, both globally and locally.

The World Health Organization (W.H.O) has also flagged it as a huge problem, as it reports, 10 percent to 25 percent of hospital and nursing home admissions result from patient noncompliance. Furthermore, about 50 percent of prescriptions filled for chronic diseases are not taken correctly, with 40 percent of patients not adhering to the treatment regimen.

In this article, just after giving a flavor to its financial cost to patients, I shall dwell mostly on its impact on the pharma players, as overcoming this important problem doesn’t generally fall in the area of strategic focus for most of them. Finally, I shall explore how drug manufacturers can translate this problem into an opportunity – as the third growth driver for business, creating a win-win situation for all.

Economic and health impact on patients:

Noncompliant patients suffering from both acute and chronic ailments, pay a heavy price, not just in terms of longer suffering arising out of complications, but also incurring significantly more health expenditure for treatment of the same diseases. According to IMS Institute for Healthcare Informatics, on average, less than 40 percent of patients around the world are fully complying with their treatment instructions.

Even in the Indian context, the problem is no different. Let me illustrate the point with the example of a chronic disease, such as Asthma. The article published on June 26, 2018 in ‘Lung India’ – the official publication of Indian Chest Society reported: “The mean annual direct costs among compliant and non-compliant patients were ₹14, 401 and ₹24, 407, respectively. Percentage of hospitalization was less among the compliant group (6 percent) when compared with noncompliant group (17 percent).”

The study concluded, asthma is not only associated with patient-specific impairment, but also creates a significant economic burden for the family and society. The major contributors to the burden are the medication cost and hospital admissions. Patient compliance with prescribed drugs can help keep asthma under control, thereby decreasing the economic burden and emergency hospital admissions – avoiding the economic risk from ill health with high out of pocket payments.  Productivity loss is another under-appreciated source of economic loss contributing to indirect cost. The rising costs of investigations, interventions, and treatment of chronic diseases further complicate the problem.

Economic impact on pharma business:

According to November 16, 2016 report, published by Capgemini and HealthPrize Technologies, globally, annual pharmaceutical revenue losses had increased from USD 564 billion in 2012 to USD 637 billion due to non-adherence to medications for chronic conditions. This works out to 59 percent of the USD 1.1 trillion in total global pharmaceutical revenue in 2015.

The report highlights, besides medication nonadherence being a serious global health issue that needs to be addressed immediately, it also happens to be a critical business issue for pharmaceutical companies. Thus, it is the only area of their business where a sharp strategic focus “can generate significant top – and bottom-line growth, improve outcomes, and create substantial savings for the healthcare system – all at the same time.”

Major reasons for patient noncompliance:

Several reasons are commonly attributed to patient-noncompliance to medicines, such as:

  • Lack of knowledge of its health and economic impact
  • Importance of completing the full-course of the drug and dosage regimen for long-term remission, following immediate relief
  • Untoward side-effects and other inconvenience
  • Forgetting therapy because of preoccupation
  • Financial inability to complete the prescribed treatment regimen due to the high cost of drugs.

Nevertheless, the 9th Edition of Global Research Report by Capgemini Consulting underscores that reality is more complex. Patient adherence initiatives, if any, when undertaken, even by pharma companies, often lack a thorough understanding of the root causes of discontinuing treatment and failure to effectively engage patients with a holistic approach to the issue. It also emphasizes: “Individual tactics are tried by different brands and then discontinued as budgets and priorities shift, before their impact is known. Successes are seldom pulled through and expanded across the organization.”

Using it as the third major growth drivers for pharma:

The two primary factors that drug manufacturers are leveraging to boost growth of the organization are:

A.  New product introduction – gradually extending to line extensions and new indications. One such illustration is the cholesterol-fighting drugLipitor of Pfizer. The lifetime sales of this brand as of the end third quarter 2017 generated a stunning USD 150.1 billion of business for the company. Incidentally, Lipitor patent expired in 2011. There are many similar examples, including Humira of AbbVie.

B.  Regular and hefty price increases for already marketed products, for various reasons, but almost regularly. According to this 2019 report, percentage price increases, on a huge base, of some of the world’s top pharma brands were as follows:

  • AbbVie: Humira, a blockbuster drug with USD 15 billion in sales in the first 9 months of 2018: +6.2%
  • Allergan: Many of its brand-name drugs, including dry-eye medication Restasis: +9.5%
  • Biogen: Multiple sclerosis drug Tecfidera: + 6%
  • Bristol-Myers Squibb: Eliquis, a drug that prevents blood clots and is on pace for USD 6 billion in sales in 2018: + 6%
  • Eli Lilly: Type 2 diabetes medication Jardiance: + 6%

Many studies have captured the importance of regular price increase, as a key pharma strategy, not only to drive the internal growth, but also to keep their investors, as well as, the stock market on the right side. There are examples that for some of the top global pharma players, this strategy was directly responsible for 100 percent of earnings-per-share growth in 2016, and more than 20 percent of the revenue made in the first three quarters of 2018.

On the other hand, some top analysts’ findings highlight that drug companies serious strategic focus just on the issue of patient noncompliance with novel tactical measures, could fetch as much as a 30 percent increase in annual earnings per share for many players, even in India.

This brings up to the point – can strategic focus to minimize patient’s non-compliance, supported by adequate resources, be the third growth driver for drug companies?

Can focus on patient noncompliance be the third growth driver for pharma?

For a moment, leaving aside the above two primary growth drivers, if we look at the estimates, as quoted above, well over 50 percent to 60 percent of a brand’s potential sales is wasted due to patient noncompliance. Isn’t it huge? Can this be ignored? Obviously not. Instead, why not pharma converts this problem into an opportunity, with a sharp strategic focus, leveraging technology.

Translating this potential opportunity into reality is neither very easy nor is every company’s cup of tea. But the reward for the winners is indeed phenomenal. To chart on this frontier, one of the toughest barriers, besides a winner’s mindset, is getting access to credible and meaningful patient-data, for various reasons. On the other hand, it isn’t an insurmountable problem, either – especially, with today’s rapidly progressing technology.

Some companies have started the long march:

According to the review article, published in the New England Journal of Medicine: ‘The ability of physicians, to recognize non-adherence is poor, and interventions to improve adherence have had mixed results. Furthermore, successful interventions generally are substantially complex and costly.’

Realizing that it as a potential opportunity – disguised as a problem, several pharma players have started thinking about exploring this not much charted territory, confirm reports coming from different countries of the world. To give an illustration, November 22, 2016 edition of Fierce Pharma reported: ‘Pharma companies have more recently joined the conversation with partnerships and programs that include adherence aims.’

It is generally believed today that rapid ascendency of modern technology, and its strong influence on people, will help create a new awareness of its current adverse impact both on patients and the drug companies.

What else could be done in a much wider scale?

Digital interventions, such as smartphone apps, are becoming an increasingly common way to support medication adherence and self-management of chronic conditions. In this regard, the May 14, 2018 study titled, ‘Smartphone apps for improving medication adherence in hypertension: patients’ perspectives’, published in the journal of Patient Preference and Adherence, concluded as follows:

‘These data showed that patients can identify the benefits of a medication reminder and recognize that self-monitoring their blood pressure could be empowering, in terms of their understanding of the condition and interactions with their general practitioners.’ But some loose knots are still to be tightened.

Tightening the loose knots:

Having leveraged the state of the part digital technologies to tighten the loose knots in this area,a host of AI-enabled smartphone health and diagnostic apps, capturing patient compliance details, especially in chronic disease areas, are fast coming up. Most of these are being developed by large, small and medium sized non-pharma pure tech companies, including startups. For example, according to reports: ‘With the release of the Apple Health Record and Apple Watch with a single-lead ECG, it’s evident that Apple has officially entered the healthcare space.’

A good number of these apps have received even the US-FDA approval, such as: MyDose Coach - a reliable dose calculating app for type 2 diabetic patients who take insulin once-daily in concert with physician guided insulin recommendations. Or, GoSpiro – a home spirometer, to measure air output from the lungs for COPD patients and connects wirelessly to provide hospital-quality data regarding breathing.

That many non-pharma entities are trying to create a space for themselves in a high-tech, but non-drug treatment segment within the pharma space, has prompted, several drug manufacturers to rewrite their marketing playbook, incorporating this ‘new notation’.

It’s real now…for some:

As the above Fierce Pharma article reported: ‘Pharma companies have more recently joined the conversation with partnerships and programs that include adherence aims; efforts from Verily and Sanofi and IBM and Novo Nordisk have recently made the news.’Further, on November 07, 2018, in another report it brings to the fore that Geisinger Health System has developed mobile apps to manage asthma with AstraZeneca, and a wearable app to manage pain with Purdue. It also joined forces with Merck to develop tools for patients and caregivers to improve care coordination and medication adherence.

Moreover, on February 09, 2019, Japanese drug major Astellas and WiserCare - a company that develops healthcare decision support solutions, announced a collaboration that includes improving patient adherence to care plans, and improve the overall care experience.

In tandem, concern on patients’ data privacy, may also now be addressed, possibly by making use of blockchain or similar technology for such initiatives, as I discussed earlier in this blog.

Conclusion:

‘Acquiring new customers is important, but retaining them accelerates profitable growth,’ is the theme of an article, published in Forbes on June 08, 2016. Therefore, just as any other business, this dictum applies to the pharma industry, as well, especially in context of patient noncompliance to medicines, with a clear strategic focus to minimize its impact on performance.

The major reasons for patient noncompliance ranges from ignorance of its adverse impact on health to side effects, forgetfulness and right up to inability to afford full-course of the prescribed drug treatment. Despite its continuity over decades, adversely impacting patients, health system and the pharma players, it won’t be prudent to infer that no attempt was being made in the past, to address this critical issue. Nevertheless, those measures have not worked, for many reasons, as we see today from various research studies in this area, even in the Indian context.

Once again, intervention of technology to make patients compliant to medicine, is showing promise for following it up more vigorously. That some global drug majors are entering into collaborative arrangements with non-pharma, technology companies of various sizes, sends a signal of the emergence of a third major growth driver for pharma, as discussed above.

This issue is so important, especially considering that the low hanging fruits of R&D have mostly been plucked, just as regular hefty increases of drug prices are meeting with tough resistance, squarely. In this scenario, a robust strategic focus on patient compliance would not only boost pharma sales but would also reduce the disease burden of a large section of people significantly. This will benefit all and harm – none.

Awaiting ‘The Moment of Truth’ on ‘Working of Patents’ in India

Posted on by

By a letter dated October 21, 2014 addressed to the Secretary, Department of Industrial Policy and Promotion (DIPP) of India, the domestic pharma major Cipla has sought for the revocation of five patents of Novartis AG’s respiratory drug Indacaterol (Onbrez) in India, under Sections 66 and 92 of the Indian Patents Act.

Launch of a generic equivalent:

Cipla also announced its decision to launch shortly a generic equivalent of Indacaterol with the brand name Unibrez Rotacaps to satisfy the unfulfilled requirement of the new drug in India.

The Maximum Retail Price for a strip of 10 capsules of Unibrez Rotacaps 150 mcg would cost Rs.130.00 to patients against the equivalent strength of Onbrez of Novartis costing Rs.677.00, which is 420 percent more expensive than the price at which Cipla would sell this drug.

What do the Sections 66 and 92 of the Indian Patents Act say?

- Section 66 of the Indian Patents Act:

“66. Revocation of patent in public interest: Where the Central Government is of the opinion that a patent or the mode in which it is exercised is mischievous to the State of generally prejudicial to the public, if any, after giving the patentee an opportunity to be heard, make a declaration to that effect in the Official Gazette and thereupon the patent shall be deemed to be revoked.”

- Section 92 of the Indian Patents Act:

“92. Special provision for compulsory licenses: (1) If the Central Government is satisfied, in respect of any patent in force in circumstances of national emergency or in circumstances of extreme urgency or in case of public non- commercial use, that it is necessary that compulsory licenses should be granted at any time after the sealing thereof to work the invention, it may make a declaration to that effect, by notification in the Official Gazette, and thereupon the following provisions shall have effect, that is to say –

(i) The Controller shall on application made at any time after the notification by any person interested, grant to the applicant a license under the patent on such terms and conditions as he thinks fit;

(ii) In settling the terms and conditions of a license granted under this section, the Controller shall endeavor to secure that the articles manufactured under the patent shall be available to the public at the lowest prices consistent with the patentees deriving a reasonable advantage from their patent rights.

(2) The provisions of sections 83, 87, 88, 89 and 90 shall apply in relation to the grant of licenses under this section as they apply in relation to the grant of licenses under section 84.

(3) Notwithstanding anything contained in sub- section (2), where the Controller is satisfied on consideration of the application referred to in clause (i) of sub- section (1) that it is necessary in –

(i) A circumstance of national emergency; or

(ii) A circumstance of extreme urgency; or

(iii) A case of public non- commercial use, which may arise or is required, as the case may be, including public health crises, relating to Acquired Immuno Deficiency Syndrome, Human Immuno Deficiency Virus, tuberculosis, malaria or other epidemics, he shall not apply any procedure specified in section 87 in relation to that application for grant of license under this section:

Provided that the Controller shall, as soon as may be practicable, inform the patentee of the patent relating to the application for such non-application of section 87.”

Two key reasons:

Anchored on the above two sections of the Indian Patents Act, the two key reasons cited by Cipla for revocation of five patents granted to Indacaterol of Novartis AG are, very briefly, as follows:

Lack of inventive steps and ‘evergreening’ of patents:

The exclusivity given to five patents of Indacaterol is contrary to law due to lack of inventive step, being obvious inventions. Novartis allegedly has indulged in ‘evergreening’ with a number of patents to extend monopoly of the drug much beyond the term of the first patent. Indian law expressly bars ‘evergreening’ as it impedes drug access to a large majority of the patients.

Lack of working of the patents:

Cipla also claimed lack of “working” of those patents in the country, as a mere 0.03 percent of the drug requirement is currently being fulfilled in India. This leaves the percentage of inadequacy in the requirement of the drug per year at a staggering number of around 99.97 percent.

With supporting details, Cipla has stated in its letter that Indacaterol under the brand name Onbrez is imported by Novartis through its licensee Lupin Pharma only. It further pointed out that the Indian law requires all patents to be “worked” within the territory of India.

While adequate quantity of imports may qualify as working, the present case is one in which the patents in question have not been worked through imports of adequate quantity of the drug. Thus reasonable requirements of the public have not been fulfilled, at all.

Abysmally low drug access to Indian patients:

According to Cipla, when there has been a necessity for the availability of Indacaterol to a much larger number of patients afflicted by COPD, that has assumed magnitude of an epidemic, just a miniscule of 0.03 percent of the total drug requirement is currently being met in the country. In 2013, the import of Indacaterol, as reportedly declared in Form 27 by Novartis to the Patent office, was just 53,844 units, which could meet this drug requirement at best of only 4,500 out of 15 million patients, annually.

Despite accepted drug benefits, the doctors are unable to adequately prescribe Indacaterol in India, due to low quantity of the drug import for the public.

Thus, while announcing the launch of cheaper generic equivalents of the drug, Cipla emphasized that its Unibrez Rotacaps would fulfill the requirements of the public, meet public health interest and at the same time increase access to this medicine, with an affordable alternative, for a large number of patients.

Increasing incidence of COPD in India:

In its application to the DIPP, Cipla underscored that Indacaterol is one of the preferred medications to treat widely prevalent Chronic Obstructive Pulmonary Disease (COPD) that has reached the magnitude of an epidemic in India with about 15 million Indians afflicted with the ailment.

COPD is now among the top ten causes of disease burden in India. According to Indian Council of Medical Research (ICMR), the overall prevalence rates of COPD in India are 5.0 and 3.2 percent respectively in men and women of and over 35 years of age. The World Health Organization (WHO) also reported that COPD is the cause of death of more people than HIV-AIDS, Malaria and Tuberculosis all put together in the South East Asian Region.

Cipla quoted an Indian Study on “Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults (INSEARCH)”, which estimated that about 7 percent of deaths annually are a result of Chronic Respiratory Diseases in India.

Importance of Indacaterol in COPD treatment:

Cipla reiterated that Indacaterol is the preferred drug over other beta adrenoceptor agonists, as it has to be consumed only once a day. Moreover, it has a higher potency and prolonged effect as compared to other beta adrenoceptor agonists.

Strong arguments make the case interesting:

Though appropriate legal authorities would take a final call on the subject, prima facie, Cipla seems to have a strong case resting on the pillars of Sections 66 and 92 of the Indian Patents Act.

Since, Cipla has already gone ahead and announced the launch of cheaper generic equivalent of Indacaterol in India, it gives a sense about the company’s confidence in its argument against five valid patents of Novartis on this drug.

On the other hand, one may also justifiably say that Cipla should have waited for the final verdict of the court of law on the validity of five Indacaterol patents in India, before deciding to actually launch a generic version of the patented drug.

It is worth noting that in 2013, Novartis lost a legal battle related to patent grant for its anti-leukemia drug Glivec in the Supreme Court of India. The case lasted over seven years in various courts of law. Interestingly, Cipla had followed similar course of action in the Glivec case too, and had won the case decisively.

‘Form 27’ and the Indian Patent office (IPO):

At this stage it is worth noting, a ‘Public Notice’ dated December 24, 2009 was issued by the Controller General of Patents, Design & Trade Marks, directing all ‘Patentees and Licensees’ to furnish information in ‘Form No.27’ on ‘Working of Patents’ as prescribed under Section 146 of the Patents Act read with Rule 131 of the Patents Rule 2003.

The notice also drew attention to penalty provisions in the Patents Act, in case of non-submission of the aforesaid information.

The information sought by the IPO in ‘Form 27’ can be summarized as follows:

A. The reasons for not working and steps being taken for ‘working of the invention’ to be provided by the patentee.

B. In case of establishing ‘working of a patent’, the following yearly information needs to be provided:

  • The quantity and value of the invention worked; which includes both local manufacturing and importation.
  • The details to be provided, if any licenses and/or sub-licenses have been granted for the products during the year.
  • A statement as to whether the public requirements have been met partly/adequately to the fullest extent at a reasonable price.

The ‘Public Notice’ also indicated that:

• A fine of up to (US$ 25,000 may be levied for not submitting or refusing to submit the required information by the IPO.

• And providing false information is a punishable offence attracting imprisonment of up to 6 months and/or a fine.

The important point to ponder now is, if Cipla’s allegation is correct, what has been the IPO doing with the ‘Form 27’ information to uphold the spirit of Indian Patents Act 2005, thus far?

Conclusion:

For various reasons, it would now be interesting to follow, how does the IPO deal with this case right from here. In any case, information provided through ‘Form 27’ cannot remain a secret. ‘The Right to Information Act (RTI)’ will help ferret more such details out in the open.

As the ‘Moment of Truth’ unfolds in this case, one would be quite curious to fathom how the strong voices against ‘non-working of patents’ and ‘evergreening’ drive home their arguments before the court of justice.

On the other hand, the global innovator companies, their highly paid lobby groups and the USTR are expected to exert tremendous pressure on the Indian Government to protect the global pharma business interests in India, come what may. All these would indeed create a potboiler, as expected by many.

In this complex scenario, striking a right balance between rewarding genuine innovation, on the one hand, and help improving access to affordable modern medicines to a vast majority of the population in the country, on the other, would not be an enviable task for the Indian Government.

As the juggernaut of conflicting interest moves on, many would keenly await for a glimpse of ‘the moment of truth’ based on the judicial interpretation of ‘evergreening’ and ‘working of patents’, for this case in particular.

Does Patent Expiry Matter Less For Difficult To Copy Drugs?

Posted on by

“Patent expiry matters much less for difficult to copy drugs”.

Not so long ago, this is what many used to believe in the pharma industry. However, looking at the current trend involving the tech savvy generic players, it appears, gone are those days even for the home grown companies in India. As we witness today, a number of global generic players, including some from India, are overcoming the tough challenge of technological barrier of the original drugs with technology, boldly and squarely, and that too with reasonably good speed.

A global CEO felt quite the same:

Possibly encouraged by this commercial dogma, the Chief Executive of GlaxoSmithKline (GSK) Sir Andrew Witty reportedly felt in not too distant past that his company’s blockbuster drug Advair/Seretide, used for the treatment of asthma, would continue to remain a major product, despite losing US patent in end 2010. Witty thought so considering the intricate technology involved in making its high tech inhalation drug delivery system with exacting precision.

Technology based entry barrier:

Although, Advair/Seretide is a respiratory inhalation drug, it is not quite like a typical aerosol inhaler consisting of a pressurized canister filled with liquid medicine formulation. In such system, as the canister is compressed, the liquid inside comes out as a spray that is breathable in an amount as required for desirable clinical efficacy for the patients.

With the application of complex technology, Advair/Seretide was formulated not as a liquid, but as pre-determined fixed dose combination of powders that patients inhale into their respiratory tracts with a device called ‘Diskus’, which involves a complex and difficult to copy inhaler technology with a long patent life.

This precision technology was expected to create the requisite entry barrier for generic equivalents of this important medicine.

“Diskus” patent to continue:

It is important to note, though Advair/Seretide had gone off patent in end 2010, the patent protection for the “Diskus” device that dispenses the powder version of the fixed dose drugs combination, continues till 2016. For the inhaler device that dispenses the aerosol version of the same drugs, the patent remains valid until 2025.

New USFDA guidance:

Keeping these factors in mind, the USFDA in its latest guidance has clearly enunciated the characteristics that an inhaler should have, including a similar size and shape to Diskus. This new USFDA guidance for inhaled drugs, like Advair/Seretide, now requires only “relatively basic” preclinical tests and a short clinical trial.

Many believe that this new guidance is mainly to ensure that other generic devices also qualify for the GSK’s asthma drug combo, after its patent expiry.

Nevertheless a challenging task:

Despite this new USFDA guidance for inhaled drugs, some large generic manufacturers apprehended, even way back in 2010, that they doubt whether it will be possible for them to adequately replicate Advair/Seretide to meet the stringent “substitution” requirements of the USFDA on generics. This is exactly what Witty had envisaged earlier.

Almost two years after its patent expiry, in October 2012, the world’s largest generic drug maker Teva also announced that the company does not expect to see true substitutes for Advair/Seretide before 2018.

No immediate sales impact post-patent expiry:

As a result, in 2012, even a couple of years after its patent expiry, Advair/Seretide could successfully weather the impending storm, though GSK reported a lackluster overall business performance. The brand at that time was virtually immune to substitution threats from generic equivalents. The key reason being, as stated above, much unlike a patented chemical drug substance, the ‘Diskus’ system of the GSK inhaler is a hell of a task to copy by meeting the regulatory requirements of substitution.

In 2013, close to three years after its patent expiry, Advair/Seretide ranked fourth within the top 10 global best-selling drugs of that year, clocking annual revenue of US $8.25 billion.

The first competition:

In the midst of all these, the first generic equivalent of Advair/Serevent with a new inhalation device, carrying a name AirFluSal Forspiro from the Sandoz unit of Novartis, started warming up to obtain regulatory approval from several countries within the European Union (EU).

The product was first approved in Denmark on December, 2013 with subsequent marketing authorizations received in Germany, Sweden, Hungary, Romania, Bulgaria, and Norway.

The heat started being felt now:

The overall position of the brand started changing thereafter. According to published reports, sales trend of Advair/Seretide in Europe and other markets are on the decline in 2014. In Europe, the drop was around 3 percent and in the US around 19 percent in the last quarter, due to a combined impact of many factors.

According to Bloomberg, the sales of Advair/Seretide are expected to drop from US$8.25 billion in 2013 to US$5.9 billion in 2016 with the entry of generics.

A large and growing market to invest into:

According to the World Health Organization (WHO), in every 10 seconds, Chronic Obstructive Pulmonary Disease (COPD) that includes conditions such as chronic bronchitis and emphysema kills one person globally. It is expected to be the third leading cause of death worldwide by 2030.  However, though more number of people suffers from asthma globally, its mortality rate is still much less, WHO says.

Bloomberg estimates that COPD market, including asthma, is expected to reach over US$30 billion by 2018.

Cipla came next crossing the ‘technology hurdle’:

Though the leader in the global generic market – Teva, expressed its inability to introduce the generic version of Advair/Seretide before 2018, this month, the Indian pharma major Cipla introduced its version of the product in two European countries, just next to Novartis. Consequently, Cipla demonstrated its ability to overcome the technological hurdle of the product faster than most others and mastering the intricate NDDS technology in record time, with precision.

The Cipla product is named as ‘Serroflo’ in Germany and ‘Salmeterol/Fluticasone Cipla’ in Sweden. As reported in the media quoting Cipla Chairman Dr. Yusuf Hamied, the product has also been launched in Croatia. By now, Cipla has obtained regulatory approvals of this product in 10 countries in total, with an approval pending in the GSK’s own domestic turf, the United Kingdom (UK). Other country-wise launches in Europe would probably take place much before the end of 2014, according to Dr. Hamied.

The product is expected to be launched in the US in the next three to four year’s time, though one media report mentioned about its 2015 launch in that market. Dr. Hamied also said that his company is now planning its first-ever manufacturing plant in America, which might focus on producing HIV medicines.

On a conservative estimate, the market analysts expect Cipla to generate around US$50 million in sales from the EU markets by 2016 and around US$110 million by 2018, as the company gains increasing market access with not more than 4-5 generic competitors competing in this segment.

Be that as it may, getting regulatory approval for launch of a generic version of Advair/Seretide in the regulated markets, by itself, is a huge achievement of technological prowess that Cipla has demonstrated, yet again.

Not too many generic competition expected:

Because of high quality technological requirements to develop a replaceable generic version of the GSK product, not too much competition is expected in this segment.

Thus far, another global generic drug major Mylan is expected to file for a generic version of Advair/Seretide in the US by the third quarter of 2015 for a 2016 launch. Besides Cipla and Novartis, Mylan, Teva and Actavis are expected come out with the generic version of this drug.

Opportunities in ‘difficult to copy’ drugs:

According to a recent ‘RnR Market Research Report’, over 1,400 drugs with New Drug Delivery System (NDDS) have since been approved globally. This includes inhalation devices too.

The oral drugs contribute the largest share of the overall NDDS market with over 52 percent of the total pie. This segment is expected to attain a turnover of over US$90 billion by 2016 at a CAGR of 11 percent. The injectable new drug delivery market is expected to reach a turnover of over US $29billion by 2015, according to this report.

I have deliberated this subject in one of my earlier blog posts titled. “Moving Up The Generic Pharma Value Chain”.

Another high tech area – biosimilar drugs:

As the high priced biologic drugs of the innovator companies go off patent, large molecule biosimilar drugs, involving high technology, would emerge as another lucrative growth opportunity for the generic players having requisite wherewithal.

Recombinant vaccines, erythropoietin, recombinant insulin, monoclonal antibody, interferon alpha, granulocyte cell stimulating factor like products are now being manufactured by a number of domestic biotech companies. Some of the Indian companies that have already entered into the biosimilar segment are Dr. Reddy’s Laboratories (DRL), Lupin, Biocon, Panacea Biotech, Wockhardt, Glenmark, Emcure, Bharat Biotech, Serum Institute, Hetero, Intas and Reliance Life Sciences, besides others.

The ultimate objective of all these Indian companies is to get regulatory approval of their respective biosimilar products in the US and the EU either on their own or through collaborative initiatives.

Overall improvement in the quality of ANDA filings:

In the last few years, overall quality of ANDA filings of the domestic Indian pharma players has also improved significantly. Their regulatory filing schedules now include many complex molecules, injectibles, oral contraceptives, ophthalmic preparations, inhalers/other drug delivery systems and biosimilars, beside Para IV/FTFs. All these are now contributing a growing share in their new product initiatives for the regulated markets.

Conclusion:

In the largest pharma market of the world – the United States, global generic companies are increasingly facing cutthroat price competition with steep price erosion, registering mixed figures of business performance and growth.

However, a new trend is fast emerging. Even when global innovator companies are including increasing number of difficult to copy medicines in their product portfolio, some pharma players are reaping a rich harvest by moving up the value chain with the generic versions of those products, post patent expiry. These copycats offer much higher margin than non-differentiated generics.

Some Indian generic companies too have started focusing on building value added, difficult to manufacture, and technology intensive generic product portfolios in various therapy areas. DRL is reportedly all set to take its complex generic drug Fondaparinux sodium injection to Canada and two other emerging markets.

Those Indian pharma companies, which would be able to develop a robust product portfolio of complex generics and other differentiated formulations for the global market, would now be much better placed in positioning themselves significantly ahead of the rest, both in terms of top and the bottom line performance.

The myth, as epitomized in the good old saying, “Patent expiry matters less for difficult to copy drugs”, seems to be partly true in delaying entry of generics immediately after the end of the monopoly period, at least, for now. However, I reckon, this gap of delay would eventually get much reduced, if not eliminated altogether, as we move on. Armed with cutting edge technology Cipla has almost busted the myth, as it came close second to Novartis with the launch of a complex generic equivalent of Advair/Seretide in the EU and other markets.

Pharma majors of the country, such as, DRL, Cipla, Lupin and Biocon, to name a few, are taking great strides, setting examples for many others to emulate and excel in this area. The groundswell has already begun for a long haul global journey of the Indian pharma into the El Dorado of high tech generics fetching higher rewards.
