To scale-up access to healthcare, especially for the marginalized population of any country, greater access to affordable generic drugs will always remain fundamental, besides improving healthcare infrastructure and its delivery mechanism.

Thus, there should be a robust mechanism across the world to facilitate quick entry of cheaper generic equivalents immediately after patent expiry of the original molecule. Any attempt to step over the line, blocking entry of generics surreptitiously by vested interests must be brought to justice sooner. Such measures assume increasing importance, as without availability of newer generics, unmet medical needs of the most vulnerable section of the society cannot be met effectively by any country.

Newer generics will play a critical role even in the Indian context. Besides many other diseases, India is already known as the diabetic capital of the world with an estimated population of 70 million diabetics by 2020.

Greater access to treatment for such chronic ailments and many other dreaded diseases with increasing trend of prevalence, like cancer, multiple sclerosis, Alzheimer and autoimmune disorders, besides common tropical diseases, would also depend on the availability of cheaper and newer generic medicines.

Global innovators stepping into generics business in emerging markets:

Sniffing the growth opportunities in the generics business in an environment of patent cliff, even many hard-nosed innovator companies have been entering into this business either through local acquisitions or through various collaborative arrangements. Examples of some of these companies are as follows:

• Novartis entered in generic business with its Sandoz arm
• Pfizer with collaborative arrangements in India with Aurobindo Pharmaceuticals (India) in March 2009 and with Strides Arcolab in January 2010
• Daiichi Sankyo acquired Ranbaxy of India
• GlaxoSmithKline acquired 16 percent stake of Aspen Pharmacare of South Africa,  Laboratorios Phoenix
in in Argentina and signed a development and commercialization license with Dr. Reddy’s Laboratories (DRL)
• Sanofi acquired Shantha Biotechnics and Universal Medicare of India, Zentiva in Czech Republic, Laboratorios Kendrick in Mexico, Medley in Brazil and Helvepharm in Switzerland
• Abbott Laboratories acquired the pharmaceutical formulations business of Piramal Healthcare and collaborated with Zydus Cadila

A pro-generic initiative in the west: 

Ireland’s parliament has recently passed a bill on pro-generic initiatives. Under this new law pharmacists will be permitted to substitute branded medicines, which have been designated by the Irish Medicines Board (IMB) as interchangeable.

Currently in Ireland, if a specific brand of medicine is prescribed for a patient, the pharmacist must supply only that brand.

Some steps over the line blocking entry of generics:

Interestingly, to continue marketing high priced innovative drugs even after patent expiry, attempts are still being made to block entry of cheaper generics through equally innovative means by stepping over the line.

On April 15, 2013 ‘The New York Times’ reported several such cases of the recent past in the United States. The report gives details of the players involved in each of these cases.

Prompted by these unfortunate incidents, the Federal Trade Commission (FTC) of the US investigated into the matter involving the American drug companies and charged many of them with ‘anticompetitive behavior’. These practices are no longer new and are being followed by some companies over a long period of time.

One of the latest and elegant, yet a very simple strategy reportedly works as follows:

• Generic drug makers need samples of patented drugs to generate required regulatory data to obtain marketing approval for launch after the molecules go off patent.
•  Some innovator companies (named in the report) refuse to sell their patented drugs to generic manufacturers for development of generic equivalents.
• Traditionally, the generic drug makers purchase their requirements from the concerned wholesalers.
•  However, because of safety concerns, drugs are now mostly sold with restrictions on who can buy them.
• This compels the generic manufacturers to ask the innovator companies for samples of the patented products.
• Unfortunately, mostly they get a negative answer.
•  In defense, innovator companies explain that they are ensuring any possible improper use of their innovative drugs and also say that no law binds any company to do business with another.

It is alleged that the companies, which most aggressively pursue such measures are those with drugs nearing end of their patent life.

The report indicates that the federal regulators in USA do consider this strategy of creative interpretation of drug safety laws, is illegal.

The news item also indicates that most of these drugs are for serious illnesses like various types of cancers, multiple sclerosis and other rare diseases costing US$ 79,000 to US$ 229,000 a year to patients.

More instances:

Another recent report  highlights that European Union’s anti-trust regulator will fine two European pharmaceutical Company and seven other drug makers for blocking generic drugs against “pay-for-delay” deals. Ranbaxy’s name also features in this report.

The report also states that brand name companies, especially in the western world, have been defending “pay-for-delay” deals to extend patents and avoid costly litigation.

It reports that in a typical case, a generic rival may challenge the patent of a brand-name competitor, which then pays the rival a sum of money to drop its challenge. Interestingly, defenders of the practice call it a legitimate means to resolve patent litigation.

A recent debate:

Another interesting development has come up with the pain killer drug OxyContin of Purdue Pharma, which went off patent in April 2013.

Just before patent expiry, Purdue Pharma reportedly reformulated and pulled out its previous version of OxyContin, without abuse-deterrent measures, from the market giving reasons related to safety and efficacy of the drug.

In the notice to the Federal Register, US-FDA reportedly said, “Compared to original OxyContin, reformulated OxyContin has an increased ability to resist crushing, breaking, and dissolution using a variety of tools and solvents.” The regulator, consequently, barred the generic companies from making copies of the older versions of OxyContin without tamper-resistant qualities.

This development, will not allow drug manufacturers like Teva and Impax to make and launch generic equivalents of older versions of OxyContin.

This report also says that similar request has been filed with US-FDA by Endo Health Solutions Inc. for safety of its old painkiller drug Opana, which could force the generic version of the drug manufactured by Impax’s going out of the market in favor of high priced medicine.

On this development the Generic Pharmaceutical Industry in America has reportedly commented, “Blocking generic drugs could mean leaving behind the millions of patients who stand to benefit from access to lower-cost versions of OxyContin”. Some experts have also expressed apprehension that such a precedent would likely to encourage many others to work for similar safety related changes to extend patent life of a product.

Having said that, it appears to be a complex regulatory issue where the possibility of drug abuse has to be carefully weighed against the benefits of low cost generic entry for greater access to patients.

‘Disparaging’ generic drugs:

Reuters , quoting the French Competition Authority, recently reported from Paris that a global pharmaceutical major has “created a doubt over the quality and the safety of generics, without any proven basis.”

As a result, the report says, the French Competition Authority has fined the drug maker 40.6 million euros (US$52.7 million) for “disparaging” generic competition.

The news report further indicates that this decision followed a complaint of Teva Sante filed in 2010 against communication practices of the branded molecule discouraging the use of its generic versions by the doctors.

The innovator company may appeal against this decision.

European Commission found similar practices:

It is interesting to note that in 2009, the European Commission also reportedly found similar practices, including ‘pay-for-delay deals’ which not only adversely impacted competition, but also delayed entry of cheaper generic drugs into the EU markets.

That said, entry of generic drugs is still not speedy in all therapy areas. In this context, a study titled, “Drug patent expirations and the speed of generic entry,” concluded that the generic industry mostly target chronic drug markets with high turnover products and entry of a generic drug is also greatly influenced by the existing branded substitutes in the marketplace.

Importance of the Indian generic drugs:

According to BCC Research, the global generic drug market is expected to grow at a CAGR of 15 percent over five years registering a turnover of US$ 169 billion in 2014.

In this market, India is now the world’s biggest provider of low priced high quality generic medicines to the developing world. The experts opine in various context, the world must ensure that this vibrant hub of generic drugs does not get adversely impacted at any cost for any vested interest.

According to Pharmexcil pharma exports from India stood at an impressive US$ 14.6 billion during 2012-13 compared to US$ 13.2 billion in 2011-12. Indian Ministry of Commerce had unfolded a ‘Strategy Plan’ to take it to US$ 25 Bn by 2013-14, which currently appears to be a very ambitious objective.

Taken together, India and China now reportedly manufacture over 80 percent of the Active Pharmaceutical Ingredients (APIs) of all drugs used in the United States.

As reported by BMJ from 2003 to 2008, in various programs supported by donor organizations like the Global Fund, generic drugs from India contributed over 80 percent of the medicines used to treat AIDS, including 91 percent of pediatric antiretroviral products and 89 percent of the adult nucleoside and non-nucleoside reverse transcriptase inhibitor markets.

In addition, India is considered to be an extremely valuable source of high quality affordable generic drugs for the treatment of cancer, cardiovascular conditions, infections and other non-infectious chronic diseases and conditions.

Allegations against Indian generic drugs:

In a situation is like these, some aberrations within the Indian generic space like, what has happened currently with Ranbaxy are, at times, made universal and blown out of proportion, probably on behalf the interested players to paint the domestic pharmaceutical industry, in general, black. There is no doubt, however, all such cases of fraud on patients, wherever these take place must be brought to justice.

The issue arises when such instances are grossly generalized. For example, an American Enterprise Institute report titled, “Cheap Indian generic drugs: Not such good value after all?” quoting US-FDA, highlights that “Pharmaceutical companies in developing countries are increasingly falsifying data about the quality of their medicines.”

It further alleges, Indian producers in particular strive to reduce costs by substituting cheaper ingredients or skimping on good manufacturing practices, and often patients and well-informed pharmacists alike will overlook the flaws.

The article laments, “Indian companies and regulators simply deny there is any difference in product quality between their products and those made in the West.”

Indian perspective to the allegation:

In response to such allegations a very recent FICCI –Heal 2012 publication titled “Universal Healthcare: Dream or Reality?” articulated as follows:

“Selected reporting of malpractices in healthcare has painted a poor picture of the sector. However, the instances of misconduct/corruption are miniscule compared to public perception.”

Some important campaigns in favor of generics:

However, a publication from ‘Global Pharmacy Canada’ says,

“Generic medications are just as safe and effective as their brand-name equivalents. All the drugs supplied by the pharmacies we deal with are government approved. The manufacturers they buy from follow strict World Health Organization (WHO) standards for Good Manufacturing Practices (GMP). One or several of the following agencies have approved these manufacturing facilities:

• Food and Drug Administration (FDA), USA
• Medicines Control Agency (MCA), UK
• Therapeutic Goods Administration (TGA), Australia
• Medicines Control Council (MCC), South Africa
• National Institute of Pharmacy (NIP), Hungary
• Pharmaceutical Inspection Convention (PIC), Germany
• State Institute for the Control of Drugs, Slovak Republic
• Food and Drug Administration (FDA), India”

Similarly USFDA comments on generic drugs as follows:

“Generic drugs are important options that allow greater access to health care for all Americans. They are copies of brand-name drugs and are the same as those brand name drugs in dosage form, safety, strength, and route of administration, quality, performance characteristics and intended use.”

“Health care professionals and consumers can be assured that FDA approved generic drug products have met the same rigid standards as the innovator drug. All generic drugs approved by FDA have the same high quality, strength, purity and stability as brand-name drugs. And, the generic manufacturing, packaging, and testing sites must pass the same quality standards as those of brand name drugs.”

The growth drivers:

According to a recent study, following are the key growth drivers of the global generic pharmaceutical industry:

• Governments’ and payers’ need to contain rapidly increasing healthcare expenditures

• A growing middle-class in emerging markets

• Longer life expectancy

• A large number of patent expiries for innovator drugs, many of them are mega blockbusters

All these have contributed to the growth of global generic industry from less than US$ 50 billion in 2004 to over $80 billion by 2011 improving global patient-access to medicines significantly.

The report also says, if a more general definition of off-patent medicines is used to define generics, estimates have placed the size of the industry at closer to $150 billion. In the United States alone, generic sales have more than tripled since 2000 and now exceed $51 billion in 2011.

Encourage speedy entry of generics:

Even the Federal Trade Commission (FTC) in a report titled “Generic Drug Entry Prior to Patent Expiration: An FTC Study,” stated as follows:

“Expenditures on pharmaceutical products continue to grow and often outpace expenditures for other consumer products. Pharmaceutical expenditures concern not only consumers, but government payers, private health plans, and employers as well. Generic drugs offer opportunities for significant cost savings over brand-name drug products.”

In its report FTC recommended that generic drugs should not experience delays when entering the market. The Commission also highlighted that both pharmaceutical innovation and cheaper generic drugs bring enormous benefits to patients.

Conclusion:

It is widely recognized that generic medicines play a key role to improve access to medicines to a very large section of population of the world.

Currently, important policy measures taken by the countries like, United States, United Kingdom, Canada, Holland, Denmark and Germany for increasing use of generic drug have started helping them to achieve this objective. At the same time, such policies are helping them to garner significant savings in their respective healthcare cost.

Out of pocket expenditure towards healthcare being around 80 percent in India, un-interrupted availability of high quality affordable generic medicines will help the patients significantly. This should, no doubt, need to be ably supported by the Government by rolling-out much awaited ‘The Universal Healthcare’ proposal of the High Level Expert Group (HLEG) appointed by the Planning Commission of India, sooner.

To improve demand of generic drugs, the prescribers too need to be influenced by the regulators, as has happened in many countries of the world.

Finally, the requirement to maintain high quality standards for generic medicines should be non-negotiable and continuously be kept under careful vigil of the drug regulators.

The complex dynamics of the global generic drugs market are indeed intriguing. It is indeed a ‘Wonderland’, as it were.

Be that as it may, in this wonderland of pharma generics, as some continue to step in and some others continue to step over the line, it is also important to understand how this industry caters to the healthcare needs of billions of poor and needy.

Respective Governments across the world should facilitate speedy entry of more number of newer generic drugs in the market. Simultaneously, the drug regulators will require bringing to justice to all those forces, which will attempt blocking or delaying entry of generics, causing great harm to a vast majority of patients across the world.
