 Wishing All My Readers A Very Happy, Healthy, Peaceful and Prosperous 2021

Just a few days left for the year 2020 to merge with history. It will be remembered by all – as a year of all-round catastrophic global disruption. With unprecedented impact on human lives, livelihoods, economy, and ways of doing things – sparing virtually nothing. The sole cause of which is an unprecedented single event – Covid-19 pandemic. As of December 27, 2020 morning, India recorded a staggering figure of 10,118,392 new Coronavirus cases with 147,659 deaths. The threat of subsequent waves for further infection of Covid-19 infection continues.

In this article, I shall focus on some critical lessons learnt from the 2020 health crisis, while crystal-gazing 2021. I’ll do this purely from the health care perspective, in general, and the pharmaceutical industry, in particular. Keeping this in view, some of the lessons learnt during the pandemic are as follows:

A. Never allow a sense of hubris setting in:

This is easier said than done. Nonetheless, before the Covid pandemic played havocs with all, many top pharma leaders were, apparently, in a hubris. It was often laced with excessive confidence, if not arrogance. The predominant belief was nothing can go so wrong sans unfavorable policy decisions by the governments. This was against a much-known management dictum for all – always anticipate future probabilities that may impact the business and keep prepared for the worst, while hoping for the best. On a hindsight, this was, obviously jettisoned – lock, stock and barrel. No one was prepared for any biological threats, such as, Covid pandemic, till the deadly virus caught the humanity off-guard around December 2019, as we see below:

The pandemic was expected, but struck unexpectedly:

A pandemic wasn’t totally unexpected either. Therefore, they question that surfaces - Experts warned of a pandemic decades ago. Why weren’t we ready? Just in 2015, even Bill Gates, during a Ted talk titled, “The next outbreak? We’re not ready,” also predicted - based on available facts that an epidemic would kill millions in the future.

He further added: “If anything kills over 10 million people in the next few decades, it’s more likely to be a highly infectious virus rather than a war – not missiles, but microbes.” Gates further emphasized: “We have invested a huge amount in nuclear deterrents, but we’ve actually invested very little in a system to stop an epidemic. We’re not ready for the next epidemic.”

B. Research on anti-infective drugs shouldn’t be pushed to the back burner: 

These warnings were, apparently, ignored by the pharma industry. For example, as reported in the first quarter of 2020, many research-based pharma companies shifted ‘resources away from emerging infectious diseases into more lucrative areas like cancer treatment. Their business decisions risk leaving gaping holes in the fight against epidemics, such as the one caused by the novel Coronavirus.’

Let’s now take a pause for pharma players to ponder. Are they ready, at least now, with a robust plan – based on almost a year’s experience of an unprecedented agony along with its customers, specifically to counter any future biological threat? Be that as it may, there have also been some good outcomes out of the Covid crisis, both for the pharma industry and also for the health care customers.

C. The pandemic hastened pharma’s digital transformation process:

As is known, compared to many other industries, pharma industry was a late learner in the digitalization process of organizations. The new realities of disruptions caused by the pandemic had significantly expedited this process to keep the business going. There were no other effective options available, either, but to move beyond business stabilization and redefine how they do business. The IQVIA article, ‘Digital transformation in a post-Covid-19 world,’ published in the Pharmaceutical Technology, on August 31, 2020, also reiterated this point.

Elaborating the point further, the article pointed out: ‘As a result, acceleration of three key capabilities is occurring to create sustainable competitive advantage,’ as follows:

  • Digital capabilities with modern technology are enabling companies doing the right things during the pandemic and accelerating the process.
  • Providing access to granular data to support the extraction of precise insights into the needs of patients and physicians.
  • Ensuring capabilities for sustaining relationships. While face-to-face interaction has been dramatically reduced, relationships with HCPs and patients are taking new shapes and are of more importance than ever before.

D. Telemedicine came under mainstream care, supported by Government:

Finding no other viable alternatives during the Covid lockdown period and the need to stringently follow prescribed health measures, many patients were pushed to search for a robust digital solution for health care needs. Just as many of them were already using online platforms to meet other regular needs. In that sense, Covid propelled health care into a virtual world, bringing telehealth or telemedicine toward mainstream care, supported by the Government with a policy, for the first time, ever.

E. Quality of pharma response to pandemic enhanced industry image:

As I had discussed before in this blog, Consumer centric communications, driven by the  ‘hope and confidence as companies rushed to come up with COVID-19 vaccines and treatments’ of all, helped to significantly enhance the industry’s image during the year. In my view, pharma shouldn’t let go this opportunity to reposition itself, to reap a rich harvest in the years ahead.

Crystal-gazing 2021: 

A. A lurking fear will keep haunting:

Moving away from the outgoing year – 2020, if one crystal gazes the incoming – yet another brand-new year – 2021, a lurking fear still haunts most peoples’ minds. Will the all-round disruptions of 2020 be the new normal in 2021 – with no further escalation of the current situation?

B. Vaccine rollout will reduce rapid spread, but not eliminate Covid-19:

Gradual rolling out of vaccines may reduce the rapid spread of pandemic, provided Covid-19 doesn’t throw more surprises, such as, complicated mutation, blunting this initiative. However, currently available evidence indicates, the new variant could be more transmissible, yet vaccines may work very well against it.

 C. Masking, physical distancing, hand washing, etc., will continue:

Besides, many yet unknown side effects, the duration of immunity following coronavirus vaccination is still largely unknown due to the simple lack of time we’ve had to study such immune responses. Moreover, the trials do not tell us if the vaccines can block the transmission of the disease from those who are asymptomatic and have been vaccinated. Thus, masking, physical distancing, hand washing, testing, treating and contact tracing, reportedly, will continue to be important in the global campaign against COVID-19, even after vaccine rollout.

D. NDDS for Covid drugs and vaccines may come: 

New formulations, new Covid drug delivery systems, newer methods to bring Covid vaccines, like nasal sprays, in a powder form for easy transportation and to reach more people around the world, are expected to commence in 2021.

E. Waiting for going back to pre-Covid game plan is a losing strategy:

Vaccines are unlikely to take us back to pre-Covid time, any time soon. Even McKinsey & Companypredicted the same in its article: ‘‘How COVID-19 is redefining the next-normal operating model,’ published on December 10, 2020. It emphasized: “With everything disrupted, going back to the same old thing is a losing strategy. The strongest companies are reinventing themselves by embracing pandemic- driven change.”

Many pharma majors are also echoing the same, even as Covid-19 vaccines have started rolling out for public in different parts of the world. After weighing-in the pros and cons of waiting, many of them have articulated: ‘We will not return to the old ways of working.’ They believe, it’s too early to put a specific timeline on turning that page now. Hence, the year 2021, working of the pharma companies is unlikely to be significantly different from the year 2020.

F. Need to capture and respond fast to changing customer behaviors:

Covid-19 pandemic is fast changing many human attitudes and behaviors, forcing organizations to respond. ‘However, the need to respond won’t end when the virus’s immediate threat eventually recedes,’ reaffirmed the Accenture article ‘COVID-19: 5 new human truths that experiences need to address.’ The massive behavior changes of key pharma stakeholders, at a never before scale and speed, will continue to prompt many leading drug companies to respond to them with well thought through digital tools, to gain competitive advantages.

G. Virtual meetings with reps, doctors and others will continue:

As witnessed in 2020, often for the first time – virtual meeting of sales reps, key opinion leaders and others will continue in 2021, even after ‘live’ ones return, but with more innovative structure and content. Pharma marketing’s long awaited and comprehensive digital foray will continue gaining a strong foothold, entering into new areas, without glancing back over the shoulder, in 2021.

H. More new drug launches will move entirely digital:

It began in 2020. For example, dozens of new drug launches moved entirely to digital, for the first time in 2020. As a pharma leader remarked, with the traditional launch framework gone during the pandemic, “we had to throw out the playbook and really embed into people’s heads that playbook is no longer meaningful. It no longer works, and we have to think outside the box.” She further added: “There’s truly no bigger place for a marketer right now. This is the new world.” None can deny this fact as we enter into the new year.

I. Success requirements of pharma professionals will be different:

With significant transformation of pharma’s operational strategies, success requirements of pharma professionals will also be significantly different in the new normal. Quick capturing and fast adaptation to the changing customer behavior for multi-channel engagement digital platforms, will be fundamentally important – not just for business excellence, but for its long-term sustainability, as well. This is a totally new and highly cerebral strategic ballgame, where obsolescence of cutting-edge technology is much faster than anything in the tradition driven old normal.

J. More pharma companies will explore inorganic growth opportunities:

More pharma companies will look for acquisitions to bridge the strategic gaps, as AstraZeneca did in 2020.

Conclusion:

In 2021, Covid Mayhem may possibly be over with a gradual rollout of vaccines. But, the impact of utter disruptions that the pandemic has caused in multiple areas of businesses in 2020, especially within the pharma industry, would continue, as we step into 2021. As the drug industry overwhelmed by Covid-19, reset themselves with the digital transformation in the new normal -for growth beyond Coronavirus, one may also view this much awaited metamorphosis, as a blessing in disguise, as it were.

Overall, as the W.H.O observed very rightly on December 27, 2020: “We throw money at an outbreak, and when it’s over, we forget about it and do nothing to prevent the next one. This is dangerously short-sighted, and frankly difficult to understand.” He further added: “History tells us that this will not be the last pandemic, and epidemics are a fact of life.” I hope, all concerned will realize this point in 2021. Alternatively, we may need to keep ourselves prepared to move, in a similar way, from the current new normal to yet unknown next normal.

Create Greater Patient–Value To Excel With Repurposed Covid Brands

Posted on by

Regular introduction of new molecules, line extensions or a Novel Drug delivery System (NDDS) has remained the life blood for pharma to rejuvenate a company’s product portfolio for driving organizational growth. But, Covid’s unprecedented and devastating assault on human lives and livelihoods, has pushed many of these initiatives off track. Covid infection was declared pandemic by the World health organization (WHO) on March 11, 2020, compelling the industry to primarily focus on finding solutions for survival, especially in the product development areas.

As the fight against time, the need for survival became so intense, there was no time for pharma companies going back to primary research, to discover new effective Covid specific drug molecules. Vaccines – at the initial stage of the pandemic, were considered by experts could be the only ‘magic bullet’, to get the humanity back again on its feet, after a fierce knockout blow by the virus. As on date, although vaccines seem to be nearer the finishing line of creating adequate initial immunity against Covid, still there are no scientifically proven drugs to predictably cure this infection.

Meanwhile, the focus of all concerned is on the existing drugs, to examine their effectiveness against Covid-19. Accordingly, right from hydroxychloroquine, dexamethasone to a number of already existing antiviral agents were repurposed for Covid treatment, under emergency approval by country regulators, pending detailed clinical trials.

For various critical reasons, experts now feel that the use various NDDS technologies in repurposing existing drugs, would create greater value for patients in Covid treatment. At the same time, this will help pharma companies to create a cutting-edge differentiator for their repurposed brands – being more patient centric. In this article, I shall dwell in this area, starting with the current status and issues with repurposed Covid drugs, as of date.

Current status and issues with repurposed Covid drugs:

According to recent reports, such as one titled ‘Formulation and delivery strategies for COVId-19 drugs,’ published by the AIchE in June 2020, more than 40 different drugs are currently being explored for efficacy against COVID-19. Unfortunately, side effects of many of these repurposed drugs limit their use in most severe cases, besides preventing their use as prophylactics.

A large proportion of repurposed Covid drugs are small-molecule medications, antivirals, and immune-modulating antibodies. These are already approved for other indications (like hydroxychloroquine, ribavirin, favipiravir), or under clinical trials, but not yet approved by the U.S. Food and Drug Administration, FDA (like, remdesivir, galidesivir, leronlimab).

If proven effective, these drugs would offer several advantages from a rapid- response perspective, such as the availability of safety data. In addition, several of these drugs offer broad-spectrum activity that makes it more likely they will remain functional even if the SARS-CoV-2 virus mutates. However, there are also exists some critical issues with repurposed Covid drugs.

Some critical issues with repurposed Covid drugs:

Let me cite below two examples, just to drive home the point of some critical medical issues, now existing with these repurposed Covid drugs:

  • Hydroxychloroquine – the malaria drug, when used as directed, commonly produces nausea, diarrhea, vomiting, besides muscle weakness. Importantly, at higher concentrations – only two to three times the daily dose, it can cause potentially fatal acute cardiovascular toxicity. Thus, the possibility of severe side effects makes the drug unattractive as a preventive measure. Drug formulation and delivery strategies, such as controlled release and targeted delivery could expand the use of such existing drugs, the report recommends.
  • The HIV drug combination lopinavir and ritonavir, which is under evaluation as a COVID-19 treatment, has side effects that include diarrhea, nausea, and liver damage. With a half-life of about 4–6 hours, the systemic concentrations can vary by a factor of eight between peak and trough. Developing a controlled-release formulation that maintains the minimum effective drug concentration, could mitigate side effects by reducing the steady-state drug concentration by as much as eightfold and reducing the burden on the liver by 81%, the above study, published by the AIchE in June 2020, highlighted.

At this point, for greater clarity, let me recapitulate what NDDS really means.

NDDS – clinical and marketing relevance:

Novel Drug Delivers Systems or NDDS generally ‘refers to the approaches, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effects.’

This process was lucidly explained in a contemporary article, which also inferred that the method by which a drug is delivered can have a significant effect on its efficacy and safety profile.

Yet another paper underscored, ‘if therapeutic agents can be made more efficacious and safer, using an improved drug delivery system, could achieve both –lucrative marketing opportunities for pharmaceutical companies, alongside advancement in the treatment of diseases of mankind.’ Moreover, NDDS can also help maintain the drug concentration in the therapeutic range for a longer period of time and deliver the content to the site of action if required.

Leaving aside the technical details behind these mechanisms let me underscore - that NDDS will be a boon for the repurposing of drugs, was also discussed in detail in an article titled, ‘Role of Novel Drug Delivery Systems in Coronavirus Disease-2019 (COVID-19): Time to Act Now,’ published on September 09, 2020.

Some broad categories of NDDS and new initiatives:

For this purpose, some of the broad categories of NDDS may include the following:

  • Sustained- or controlled drug delivery systems provide drug action at a pre-determined rate.
  • Localized drug delivery devices for drug release in the vicinity of the target.
  • Rate – pre-programed drug delivery systems.
  • Targeted drug delivery provides drug action by using carries, which recognize their receptor at the target.

It goes without saying that NDDS mechanism may be used both for new molecules that may eventually be developed, and also for the existing repurposed drugs for Covid treatment.

Some encouraging initiatives of NDDS for Covid drugs:

The encouraging news is pharma initiatives in this regard has already commenced. For example, unprecedented interest in inhaled delivery of antiviral drugs has led to Aerogen’s involvement in multiple COVID-19 drug development initiatives, with more than 15 leading pharmaceutical companies - worldwide.

Several of these collaborations are already in clinical trials. Others are also on track to enter studies on moderately and severely ill COVID-19 patients, the Press Information of Aerogen dated October 22, 2020 highlighted. Let me cite below two more examples in this area, to explain the intensity of work that has commenced in the NDDS space for repurposed Covid drugs.

Covis Pharma’s inhaled glucocorticoid, Alvesco (ciclesonide) has entered Phase III safety and efficacy trial in 400 non-hospitalized patients  -12 years of age and older with symptomatic COVID-19. The product is delivered twice daily via a pressurized metered dose inhaler (pMDI).

Senzer Pharmaceuticals - a UK based company, is also in the process of formulating two specific medicines with antiviral properties, to allow them to be inhaled directly into the respiratory tract. The primary aim is to reduce the number of COVID-19 patients requiring intensive care treatment. Senzer is also using a pMDI for targeted drug delivery of actives through inhalation, as it offers potential advantages over oral intake. These include, ease of administration, assisting early treatment, allowing a lower dose by reducing unwanted side effects and supporting the safety profile of the products.

Experts consider preparations of inhalable particles for local delivery is a simpler approach. This is because the lungs comprise only about 2% of the total body weight, targeted delivery could reduce the amount of drug required by a factor of 50 or more, as compared to oral administration.

Be that as it may, the primary purpose of all such initiatives is to ensure more effective and safer drug delivery to Covid patients. It is now up to the pharma marketing leadership to ascertain how to leverage such NDDS opportunities to deliver extra patient-value, simultaneously creating a cutting edge for marketing these repurposed brands.

Impact of Covid on the NDDS market segments:

The May 11, 2020 report titled, ‘Drug Delivery Systems Market Forecast, Trend Analysis & Competition Tracking – Global Market Insights 2020 to 2025,’ presents some interesting details in this area. It forecasts, the global drug delivery systems market shall register an upswing, expanding at a strong CAGR of 7.0% during the forecast period (2020-2025).

The ongoing COVID-19 pandemic is expected to further heighten prospects of NDDS, with the number of infections still increasing every day. Consequently, many leading pharma companies have accelerated production of essential drug delivery systems, as stated above. According to the above report, the key growth drivers of the NDDS market include:

  • Targeted drug delivery - being most dominant, is expected to capture nearly half of the global NDDS market, expanding at a healthy CAGR of 6.8% across the above forecast period.
  • Polymeric drug delivery segment is anticipated to be the second-most lucrative area, expanding at a CAGR of 7.3% across the forecast period. The popularity of this delivery type is attributed to its efficiency in localized drug delivery in large amounts, alongside lowering drug toxicity rate. The polymeric drug delivery segment is expected to capture more than 1/3rd of the global drug delivery systems market during the forecast period.
  • Application of nanotechnology is another key growth determinant for the segment. Insertion of nanoparticles help penetrate the targeted tissue in a much better manner. These particles are easily absorbed by cells, facilitating efficient drug delivery.
  • Microneedle drug delivery helps deliver vaccines or other drugs across various barriers.

Conclusion:

The Covid clock keeps ticking. As on November 22, 2020 morning, India recorded a staggering figure of 9,095,908 of Coronavirus cases with 133,263 deaths. The average number of daily new cases appeared, after the festive season, have started climbing up again. The threat of subsequent waves for further spread of Covid infection now looms large.

In this regard, many experts initially thought that Covid vaccines will be magic bullets to win the war against the new Coronavirus. But in the most recent times, this situation has changed, and it is no longer so – not even Pfizer vaccine. Indian media also deliberated the same on November 05, 2020.

Under this backdrop, Arthur L. Caplan, professor of bioethics at New York University’s Grossman School of Medicine, who wrote a 2017 book on vaccine ethics and policy have also made a profound comment. He said recently: “We’re going to have to continue our behavioral efforts - the masking and distancing and the quarantining and the testing and so on — in parallel with vaccination because it would be very, very surprising if we got a very highly effective vaccine first one out of the box.”

Currently, the world doesn’t have any clinically proven new Covid treatment drugs, either. What we have now is a number of repurposed Covid drugs, many of these are in advanced stage of clinical trials. As and when these are approved by the country’s regulators, pharma marketers will have a task cut to excel with those – among many ‘me-too’ types. In this scenario, there will be a critical need to create greater patient-value with a company’s own repurposed brand, where right application of NDDS technology could play a game changing role. The time to keep pondering is over. Time to decide is – now.

Does Patent Expiry Matter Less For Difficult To Copy Drugs?

Posted on by
Reply

“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.

NDDS as New Drug: Good for Patients, Great for Pharma

Posted on by

The Ministry of Health of India has reportedly decided to amend Rule 122 (E) of the Drugs and Cosmetics Rules, 1945 to categorize the New Drug Delivery Systems (NDDS), including ‘Controlled Release (CR)’ or ‘Modified Release (MR)’ formulations, whether a copy of studied and approved drugs or a new one, as ‘New Drugs’.

After the amendment, all vaccines and recombinant DNA (r-DNA) derived drugs would also fall under this nomenclature. Accordingly, to obtain ‘Marketing Approval’, such formulations would be subjected to requisite studies, including ‘Clinical Trials (CT), as specified for ‘New Drugs’ under the Drugs and Cosmetics Act of India.

It has however been clarified though, that these applications will not be treated as Investigational New Drugs (IND) and the Central Drugs Standard Control Organization (CDSCO) shall prepare appropriate regulatory guidelines for all NDDS formulations.

The main reason for the amendment is possibly much late realization of CDSCO that such formulations are vastly different from each other with respect to both efficacy and toxicity.

Besides, it has been widely alleged that some pharma companies in India, mainly to hoodwink the Drug Price Control Orders (DPCO) in the past, used to switch over from ‘Immediate Release (IR)’ formulations to products with CR/MR technology of the same molecule. However, that loophole has since been plugged in DPCO 2013, creating almost a furore in the industry.

A long overdue decision for patients’ health safety:

As stated earlier, this is indeed a long overdue decision of the Indian drug regulatory policy makers, solely considering patients’ health interest.

The primary reason being, any NDDS formulation with CR/MR technology is designed to release the drug substance in a controlled manner with high precision to achieve desired efficacy and safety, quite unlike its IR equivalent, if available in the market. It is important to note that inappropriate release of the drug in any CR/MR formulation would result in lesser efficacy or increased toxicity, jeopardizing patients’ health.

Process followed by US-FDA for CR/MR formulations:

In the United States, for marketing approval of such products, FDA usually requires submission of New Drug Applications (NDAs) providing details based on the evidence of adequate drug exposure expressed by blood levels or dose, and the response framework validated by clinical or surrogate endpoint(s).

US-FDA has three types of NDAs for MR drug products:

  • IR to CR/MR switch
  • MR/CR to MR/CR switch with unequal dosing intervals
  • MR/CR to MR/CR switch with equal dosing intervals

For switching from an IR to a CR/MR product, which is more common in India, the key requirement is to establish that the new CR/MR product has similar exposure course of the drug as compared to the previously approved IR product, backed by well-documented efficacy and safety profile. If not, one efficacy and/or safety trial would be necessary, in addition to three clinical pharmacology studies.

Good for patients:

The good news for patients is that, being categorized as ‘New Drugs’, all NDDS formulations, without any exceptions whatsoever, would henceforth obtain marketing approval only from the Drug Controller General of India (DCGI), after having passed through intense data scrutiny, instead of State Drug Authorities where getting a manufacturing license of such formulations is alleged to be a ‘child’s play’. Thus, with the proposed amendment, efficacy and safety concerns of CR/MR formulations are expected to be addressed adequately.

Great for Pharma:

Currently, while fixing the ‘Ceiling Prices (CP)’ under DPCO 2013, National Pharmaceutical Pricing Authority (NPPA) treats CR/MR formulations at par with IR varieties of the same molecules having the same dosage strength.

Thus, categorization of all NDDS formulations as ‘New Drugs’, irrespective of the fact whether these are copies of studied and approved drugs or new ones, would be lapped up by the manufacturers from product pricing point of view. All these formulations, after the proposed amendment, would go outside the purview of drug price control under Para 32 (iii) of DPCO 2013, which categorically states that the provisions of this order shall not apply to:

“A manufacturer producing a ‘new drug’ involving a new delivery system developed through indigenous Research and Development for a period of five years from the date of its market approval in India.”

A similar past issue still haunts:

Similar callousness was exhibited in the past, while granting marketing approval for a large number of highly questionable Fixed Dose Combination (FDC) drugs by the same drug regulators. Unfortunately, that saga is still not over, not just yet. 

All these irrational FDC formulations, even after being identified so by the Drug Technical Advisory Board (DTAB), have been caught in the quagmire of protracted litigations. Consequently, such dubious products are still being promoted by the respective pharma players intensively, prescribed by the doctors uninhibitedly, sold by the chemists freely and consumed by patients ignorantly. With ‘pharmacovigilance’ being almost non-functional in India, the harmful impact of these drugs on patients’ health cannot just be fathomed.

Conclusion: 

With the above examples, it is quite clear that technological precision of high order is absolutely imperative to manufacture any effective CR/MR formulation. In addition, stark regulatory laxity in the marketing approval process for these drugs is a matter of great concern.

In such a scenario, one could well imagine how patients’ health interests are being compromised by not formalizing and adhering to appropriate regulatory pathways for marketing approval of such drugs in the country, since decades.

That said, as the saying goes “Better Late, Than Never”. The ‘New Drug’ nomenclature of all CR/MR formulations or for that matter entire NDDS as a category, including vaccines and recombinant DNA (r-DNA) derived drugs, would now hopefully be implemented in India, though rather too late, a much welcoming decision nevertheless.

Collaborative commercialization of inexpensive smaller incremental innovation in Chemistry will play an important role in bringing affordable new drugs or new drug delivery systems

It started in the 17th century:

Alchemy, a medieval chemical science and speculative philosophy aiming to achieve the transmutation of the base metals into gold, searching for a universal cure for disease and indefinitely prolonging life, not considered a science by many, gradually became the basis for the development of chemistry into the 17th century. However, perceivable impact of chemistry on humanity, through its smaller incremental innovation, started being felt only in the second half of the 19th century.

Chemistry – an interface between the physical world and humanity:

Experts in this field often opine that the current form of human civilization has been made possible, to a great extent, through significant advancement of such innovation in chemistry and its role in modern technology. Chemistry is indeed an interface between the physical world on the one hand and the humanity on the other.

Getting a perspective of resource and time requirements for such initiatives:

Is there any similarity between development of pharmaceutical chemistry and IT software?

Now a days, one finds a striking similarity between small incremental innovation in IT software and the same in pharmaceutical chemistry. Both are creative and belong to the knowledge economy. Scientists in both the communities try to generate innovative ideas, which can lead to their effective commercialization.

Resource requirements for these two are strikingly different:

However, the nature of the commercialization process of these two sciences, though seemingly similar in terms of innovativeness, is indeed quite different. In the software community, two people can implement an idea with minimal resource requirement and could end up with a profitable commercialized product, without much difficulty. In contrast, two chemists may come up with a brilliant idea, which in many cases, may require significant investment of resources much before to even think to get the initial product commercialized. Subsequent steps of scaling up will be a separate issue altogether, with more resource commitment.

The process of commercialization of smaller incremental innovation in pharmaceutical chemistry is much longer:

As we all know, the process of commercialization of incremental innovation in chemistry takes a much longer time scale, as these are not usually spare time projects, unlike computer softwares. The cost involved in testing out and implementing a new idea in chemistry is very high and may not even be possible without any robust institutional backing.

Target inexpensive smaller incremental innovation in pharmaceutical chemistry:

Some illustrative examples of such smaller incremental innovation in chemistry are as follows:

1. Development of pharmaceutical co-crystals

2. Merger of chemistry of traditional and modern medicines for synergy in both efficacy and safety

3. Chemical technology switch: taking technology of one field and transferring it to a different field to get a new drug substance

4. Application of polymorphic chemistry in drug discovery.

The process has begun:

International experience:

The chemistry department of Oxford University, U.K, which is incidentally the biggest chemistry department of the western world, has made significant advances in commercializing incremental innovation in chemistry. Among many, they created and commercialized the following three entities through such incremental innovation:

• Medisense

• Oxford Molecular

• Oxford Assymetry

The Indian experience:

Despite all challenges, in India, as well, the commercialization process of smaller incremental innovation in chemistry has already begun. The Chemistry Department of the University of Delhi has developed 11 patentable technologies for improved drug delivery system using nano-particles. One of such technologies was development of ‘smart’ hydrogel nano-particles for encapsulating water-soluble drugs. This technology was sold to Dabur Research Foundation in 1999.

Another nano-particle drug delivery technology in opthalmogy area was also commercialized by transferring it to Chandigarh based Panacea Biotech Ltd.

Conclusion:

This process is expected to gain momentum in our country too, contributing significantly to the progress of the healthcare sector of the nation. “Commercializing smaller incremental innovation in Pharmaceutical Chemistry”, I reckon, will play a key role in providing affordable modern medicines to a vast majority of the population, as India transforms itself into a knowledge superpower.
