FDC Saga: Defiant Manufacturers, Sloppy Regulators and Humongous Inaction

“TO SIN BY SILENCE WHEN THEY SHOULD PROTEST MAKES COWARDS OF MEN”       – Abraham Lincoln

The ghost of untested, irrational and even of bizarre kind of Fixed Dose Combination (FDC) drugs, which continue to be launched, promoted, prescribed and sold freely across the length and breadth of India, has started haunting the Ministry of Health of India, yet again, in 2013. 

Though the issue originated decades ago, in 1988 appropriate ‘Rule’ of the Drugs and Cosmetics Act of India was amended suitably to have a firm regulatory grip over this situation. Despite this much awaited amendment, the situation almost went astray with incessant market entry of a large number untested FDC medicines of dubious medical rationale.

A free for all situation, as it were, in the FDC arena, continued to be facilitated by blatant laxity on the part of, especially, the state drug regulators by allowing unfettered market entry of such drugs, ignoring the CDSCO directive.

On the other hand, the Central Drugs Standard Control Organization (CDSCO), despite its statutory powers,  continued to suffer from humongous inaction untill the issue resurfaced again in 2007 and then of course, now in 2013.

The WHO Model:

The 2005 ʹProcedure to update and disseminate the WHO Model List of Essential Medicines, Criteria for Selection’ includes the following statement regarding Fixed Dose Combination products (FDCs):

ʺMost essential medicines should be formulated as single compounds. Fixed‐dose combination products are selected only when the combination has a proven advantage over single compounds administered separately in therapeutic effect, safety, and adherence or in delaying the development of drug resistance in malaria, tuberculosis and HIV/ AIDS.ʺ

Thus, FDCs:

  • Need to demonstrate clinical efficacy and safety beyond the individual drugs when given alone.
  • Need to ‘demonstrate bioequivalence of the single combined dose unit with the components administered in the same doses separately but concomitantly’.

‘Adherence’ aspect of WHO Model for FDCs is also important. Problems with ‘adherence’ could lead to inadequate and inconsistent dosing, which in turn could lead to development of drug resistance.

With robust and unquestionable medical rationale, FDCs are expected to provide superior efficacy and improved compliance without causing any untoward risk to patients.

A major disadvantage:

However, one of the major disadvantages with the FDCs is lack of flexibility in adjusting dose of individual ingredients, even if it is required for some patients. Internationally, most popular example is the FDCs of antiretroviral drugs for HIV infected patients like, Combivir, Trzivir, Kaletra etc.

Interestingly, in India there are FDCs for almost all disease areas from allergic disorders to Wolf-Parkinson-White syndrome (exaggerated), as it were.

Market attractiveness for FDCs in India: 

The domestic market for FDCs is very large and growing much faster, in sharp contrast to the western world. The following table will vindicate this point:

Thus, because of growing market demand, pharmaceutical companies in India tend to market FDCs of all different permutations and combination, at times even crossing the line of any ‘sound medical rationale’. For this reason, we find in the website of ‘Central Drugs Standard Control Organization’ (CDSCO), the banned list of so many FDCs.

A messy regulatory situation:

Introduction of new FDCs does not only warrant a ‘sound medical rationale’ but also ‘strict conformance to all prescribed regulatory requirements’ for patients’ interest. 

To check unfettered market introduction of potentially harmful FDCs, the Ministry of Health issued a Notification in September 1988, including FDCs in Rule 122 E of the Drugs & Cosmetics Rules (D&CR) 1945.

In effect, it removed the powers of the State FDAs to give manufacturing or marketing approval of FDCs. After the notification was issued, all manufacturers/marketers of all new FDCs are required to apply only to the Drug Controller General of India (DCGI) under Rule 122E of the D&CR 1945 as a new drug, along with the stipulated fees by way of a Treasury Challan.

Since this entire process entails appropriate regulatory data generation, besides  time and expenses involved, the above ‘Rule’ was continuously and deliberately broken and manufacturing and marketing approvals for various types of FDCs falling under ‘new drug’ category were regularly sought and granted by the State Drug Controllers.

Many believe that the State FDAs were equally responsible for knowingly flouting the Law, as were the pharmaceutical manufacturers.

Patients’ safety – the foremost concern:

Despite serious concerns expressed by a Parliamentary Standing Committee, this complicity resulted in the market being flooded with ‘irrational combinations’ which posed a real threat to patients’ interest and safety. The State FDAs were reminded of the notification by the earlier DCGI.

294 FDCs were banned by the DCGI in 2007. Thereafter, the important issue of patients’ interest and safety got converted into a legal quagmire, as many FDC manufacturers chose to go to the court of law to protect their business interest and also managed to obtain a ‘Stay’ order from the Madras High Court. The matter is still subjudice.

Be that as it may, those 294 FDCs banned by the Ministry of Health of India on health and safety grounds continue to be promoted, prescribed and sold to patients across India without any hindrance, whatsoever.  

Untangling the messy knot:

As the issue got entangled into prolonged litigations, the CDSCO took initiative of resolving this contentious issue again in 2009 with the help of an expert committee, involving the manufacturers.

This subcommittee cleared 48 FDCs under ‘similar FDCs already approved’, after discussing the merits and demerits, including pharmacodynamics, pharmacokinetics, side effects, dosage, medical rationale etc. of each ingredient and the combinations. The decision of the Sub Committee was then submitted to the Drug Technical Advisory Board (DTAB).

After formal approval of DTAB, these combinations are construed to be new drugs and any company wishing to market/manufacture the formulation would require submitting its Application in Form 44 to the DCGI to get approval in Form 45.

This decision was expected to send a clear signal to all concerned that resorting to any form of shortcuts to bypass strict adherence to prescribed regulatory requirements, could seriously jeopardize patients’ interest and safety. The same process was subsequently followed for the balance 142 FDCs, as well.

Thereafter, a special committee was again appointed by the CDSCO in 2013 to look into this matter in a holistic way. However, such sporadic knee-jerk reactions have failed to deliver any tangible results in this area – not just yet.

The saga continues:

Even after the above critical decision of the DTAB the saga still continues.

In March 2013, by a written reply, the Minister for Health and Family Welfare reportedly informed the Lok Sabha (the lower House of the Parliament) that in twenty three cases of new FDC, licenses have been granted by the State Licensing Authorities (SLAs) without the mandatory approval of the DCGI and action will be taken in all these cases.

However, no one seems to know, as yet, what action the Government has taken against those errant officials.

Current scenario:

Recently, the Directorate General of Health Services (DGHS) by a notification to State Drug Controllers has reportedly ordered all manufacturers of new FDC products, licensed locally before October 2012 without CDSCO permission, to submit safety and efficacy data prior to 30 August 2013.

This decision of DGHS has created a furore within the concerned FDC manufacturers, yet again, the possible outcome of which is yet to be ascertained.

The State Drug Controllers had issued manufacturing licenses for these FDCs prior to October 2012. At that time concerned manufacturers were given 18 months time period to prove efficacy and safety of these medicines to the DCGI. Regrettably, as per the above report, the DCGI has confirmed that he has received hardly any response from the FDC manufacturers till date on this regulatory requirement.

CDSCO has also stated that manufacturers, who will fail to submit the required data by the deadline run the risk of having their products banned from the market.

Before this, the State Drug Controllers were informed about this requirement on January 15, 2013.

At this point it is worth mentioning, the DCGI in October 2012 had reportedly also barred the State Drug Controllers from granting manufacturing licenses to pharmaceutical companies under brand names of the drugs, directing them to strictly issue licenses under generic name of the molecule. Additionally, he also asked the state licensing authorities not to grant licenses to combination drugs, which are technically ‘new drugs’ and fall within the domain of DCGI only.

Conclusion:

This logjam with FDCs certainly cannot continue in perpetuity, neither should such regulatory sloppiness be acceptable to any right thinking stakeholder.

All blatant violations of Drugs and Cosmetics Act of India must be stopped forthwith and the violators be brought to justice without delay. Patients’ health interest, as required by the drug regulators, is non-negotiable.

The order of DGHS asking all manufacturers of new FDCs, licensed locally before October 2012 without CDSCO permission, to submit safety and efficacy data prior to 30 August 2013, should not follow recently reported Pioglitazone type of volte face, once again, under similar outside pressure.

It is high time now for the Government to bring the unending saga of  irrational and harmful FDCs, orchestrated by defiant manufacturers, encouraged by sloppy regulators and catalyzed by humongous systemic inaction, to its logical conclusion, for patients’ sake.

Pioglitazone Conundrum: Should The Drug Regulator Step Over The Line?

Recent order of the Indian drug regulator to withdraw all formulations of the well known, yet controversial, anti-diabetic drug – Pioglitazone from the domestic market has created a flutter in the country, ruffling many feathers at the same time.

Withdrawal of any drug from the market involves well-considered findings based on ongoing robust pharmacovigilance data since the concerned product launch. To ascertain long-term drug safety profile, this process is universally considered as important as the processes followed for high quality drug manufacturing and even for R&D.

A paper titled, “Withdrawing Drugs in the U.S. Versus Other Countries” brings to the fore that one of the leading causes of deaths in the United States is adverse drug reaction. Assessing enormity and impact of this issue, the United Nations General Assembly for the first time in 1979 decided to publish a list of banned pharmaceutical products that different countries may use for appropriate decisions keeping patients’ safety in mind, as they will deem necessary from time to time.

An interesting finding:

Quite interestingly, the paper also highlights:

“There are a number of pharmaceuticals on the market in the USA that have been banned elsewhere and similarly, there are some drug products that have been banned in the United States, but remain on the market in other countries.”

Different policies in different countries:

The reason for the above finding is mainly because, various countries follow different policies to address this important health related issue. For example, though the United States will withdraw drugs based on the decision taken by its own FDA, it will also compare the action taken by countries like, UK, Japan, Australia and Sweden on the same subject.

However, many experts do believe that United Nations must take greater initiative to make all concerned much more aware about the UN list of dangerous drugs, which should be continuously updated to expect the least.

Need transparency in pharmacovigilance:

Pharmacovigilance has been defined as:

“The task of monitoring the safety of medicines and ensuring that the risks of a medicine do not outweigh the benefits, in the interests of public health.”

An article on Pharmacovigilance by A.C. (Kees) van Grootheest and Rachel L. Richesson highlights as follows:

“The majority of post marketing study commitments are never initiated, and the completion of post marketing safety studies (i.e., phase IV studies) declined from 62% between 1970 and 1984 to 24% between 1998 and 2003.”

Thus, in many countries, due to lack of required transparency in the pharmacovigilance process, harmful drugs continue to remain in the market for many years before they are withdrawn, for various reasons.

The above paper strongly recommends, “While there might be monetary benefits for each country in keeping these drugs on the market, the U.N. must step up the visibility of the withdrawal of dangerous drugs list.”

Recent Pioglitazone withdrawal in India:

Recently in India, the Ministry of Health under Section 26A of the Drugs and Cosmetics Act, 1940 has suspended the manufacture and sale of Pioglitazone, along with two other drugs, with immediate effect, through a notification issued on June 18, 2013.

As per the Drugs and Cosmetic Rule 30-B, import and marketing of all those drugs, which are prohibited in the country of origin, is banned in India. Just as in the United States, the Ministry of health, while taking such decisions in India, compares long-term safety profile of the concerned drugs in countries like, USA, UK, EU and Australia.

A Parliamentary Standing Committee of India has already indicted the drug regulator for not taking prompt action on such issues to protect patients’ treatment safety.

Pioglitazone: the risk profile:

In India:

A leading medical journal (JAPI) cautions:

“Given the possible risk of bladder cancer, physicians have to be extremely careful about using pioglitazone indiscriminately in the future.”

The JAPI article continues to state:

“We require more robust data on the risk of bladder cancer with pioglitazone and Indian studies are clearly needed. Till that time, we may continue the use of this drug as a second or third line glucose-lowering agent. In all such cases, the patient should be adequately informed about this adverse effect and drug should be used in as small a dose as possible, with careful monitoring and follow up.”

In the USA:

In 2011 The US FDA as a part of its ongoing safety review of pioglitazone informed physicians and the public that use of this drug for more than 12 months is linked to an increased risk of bladder cancer.

The USFDA review is reportedly based on “an ongoing 10-year observational cohort study as well as a nested, case-control study of the long-term risk of bladder cancer in over 193,000 patients with diabetes who are members of the Kaiser Permanente Northern California (KPNC) health plan.”

Based on this finding US FDA directed that physicians should:

  • Not use pioglitazone in patients with active bladder cancer.
  • Use pioglitazone with caution in patients who have a prior history of bladder cancer, adding, “The benefits of blood sugar control with pioglitazone should be weighed against the unknown risks for cancer recurrence.”
  • Tell patients to report any signs or symptoms of “blood in the urine, urinary urgency, pain on urination, or back or abdominal pain, as these may be due to bladder cancer.”
  • Urge patients to read the pioglitazone medication guide.
  • Report adverse events involving pioglitazone medicines to the FDA MedWatch program.

The moot point:

Considering the above US FDA directives in the Indian context, the moot point therefore is, whether it will be possible for the drug regulator to ensure that physicians and the patients in India follow such steps for drug safety with pioglitazone?

In Canada:

Another new Canadian study has again reportedly linked Pioglitazone with risks of bladder cancer and cautioned, “physicians, patients and regulatory agencies should be aware of this association when assessing the overall risks and benefits of this therapy.”

Pioglitazone and its combinations banned in France and Germany:

After a government-funded study, tracking diabetics from 2006 to 2009, concluded that Pioglitazone increases bladder cancer risk, the French Medicines Agency (FMA) announced withdrawal of Pioglitazone along with its fixed-dose combination with Metformin, as well.

FMA also advised doctors to stop prescribing Pioglitazone, plain or in combination, and asked patients, who are on this drug to consult their doctors immediately.

Simultaneously, German health authorities also acted on similar lines.

An intriguing comment by the Indian drug regulator:

Keeping all these in view, it is indeed intriguing to note that the Indian drug regulator is reportedly open to re-examine the case of pioglitazone and revoking its ban in India, if strong scientific evidences emerge in support of safety and efficacy of the drug.

However, the question then comes up is what more new scientific evidences that the Indian drug regulator is now expecting, especially when the pharmacovigilance studies are almost non-existent in India?

Moreover, such comments of the drug regulator not only prompt raising doubts about the fragility and hastiness of his own decision of banning Pioglitazone in India, but also amply demonstrate lack of seriousness in his part on this extremely important decision on drug safety?

‘Drug Product Liability Claims’ in India virtually non-existant:

In most of the developed countries, appropriate regulations are in place for product liability claims.

Under this law, if any patient suffers injury in any form while administering  a pharmaceutical drug, the patient concerned is eligible to make pharmaceutical-drug-based product liability claims, which usually involve a huge amount of money by any imaginable standard.

These claims are based on:

  • Improperly marketed pharmaceutical drugs. This category includes:

- Failure to provide adequate or accurate warnings regarding a dangerous side effect.

- Failure to provide adequate instructions on safe and appropriate use of the drug.

- The “bad advice”, which may have been given by the manufacturer or by a doctor, pharmacist, sales rep, or some other medical provider.

In the United States drug safety and effectiveness related litigations reportedly also include:

-        Criminal and civil complaints brought by the U.S. Department of Justice.

-        Lawsuits brought by state Attorney Generals and private plaintiffs under state consumer protection acts and other causes of action.

In India, closer to the above system there is a law in paper, named as “Products Liability”. This law deals with the liability of manufacturers, wholesalers, distributors, and vendors for injury to a person or property caused by dangerous or defective products. The aim of this law is to help protecting consumers from dangerous or defective products, while holding manufacturers, distributors, and retailers responsible for putting into the market place products that they knew or should have known were dangerous or defective. However, in reality, there are hardly any damages slapped by consumers on to the manufacturers in India under this ‘Product Liability’ law.

It may sound however bizarre, but is a hard fact that many drugs in Fixed Dose Combinations (FDCs) had never even gone through any form clinical trials on human volunteers before they were for the first time allowed to be marketed in India by the drug regulators.

In absence of any active steps taken by the government to educate and encourage patients to make use of this law, patients, by and large, would continue to pay a heavy price for their ignorance, keeping their mouth shut all the way, while using:

- Defectively manufactured pharmaceutical drugs.

- Pharmaceutical drugs with dangerous side effects.

- And even improperly marketed pharmaceutical drugs.

As stated before, it is worth repeating, neither is their any functional pharmacovigilance system in place in India.

Drug product liability suit for Pioglitazone in the United States:

Just to cite an example, one report indicates:

“According to court filings, all of the Actos (Pioglitazone) lawsuits pending in the Western District of Louisiana allege Takeda Pharmaceuticals failed to provide adequate warnings to doctors and patients regarding the drug’s association with an increased risk of bladder cancer. Last month (April, 2013), the nation’s first trial involving Actos bladder cancer allegations ended with a Los Angeles Superior Court jury awarding $6.5 million to a plaintiff who was diagnosed with the disease after taking the drug for four years”. However, the judge overseeing the case granted Takeda Pharmaceuticals’ request to set aside the verdict.

The report also indicates, ‘more than 1,200 Actos bladder cancer claims are pending in the Louisiana litigation. Additional Actos lawsuits have been filed in state litigations in California and Illinois.’

Indian doctors and manufacturers protest together against Pioglitazone ban:

It is equally intriguing to note, despite serious life threatening side-effect and restricted usage profile of Pioglitazone, as established internationally through robust and large clinical studies, both the doctors and the Pioglitazone manufacturers in India are urging the government to lift ban on this drug immediately, keeping the silent patient community in the front line, as usually happens all over.

news report highlighted that ‘doctors flayed the ban on anti-diabetes drug Pioglitazone and requested the Centre to reverse its decision in interest of patients.’

Another media report highlighted, major drug makers are strongly opposing the move of the government to ban Pioglitazone, in India.

Conclusion:

Without generating another set of robust evidence proving contrary to what has been already concluded in the United States and EU based on strong supporting pharmacovigilance data, if the Indian drug regulator revokes the ban of Pioglitazone, it will be construed as a huge compromise with patients’ safety interest with this drug.

This issue assumes even greater importance, when the ‘drug product liability’ system is almost dysfunctional in India.

The other alternative of the drug regulator is to revoke the ban, wilting under combined pressure of the manufacturers and doctors and ask for safety warnings trying to emulate, as it were, what has been done by the US FDA.  

In which case, with full knowledge that it is virtually impossible for any one to comply with the above US FDA requirements in India, will the drug regulator not step over the line, yet again?
