Transparency in Drug Trial Data: Thwarted by Lobbyists or Embroiled in Controversy?

Posted on by

Based on a leaked letter from overseas pharma industry bodies, a leading international daily in late July 2013 reported:

“Big pharma mobilizing patients in battle over drugs trials data.”

Some experts consider it as a poignant, if not a bizarre moment in the history of drugs development, keeping patients’ interest in mind. However, the concerned trade bodies could well term it as a business savvy strategy to maintain sanctity of ‘Data Exclusivity’ in real sense.

That said, it is important for the stakeholders to figure out where exactly does this strategy stand between the larger issue of patients’ drug safety and efficacy concerns and the commercial interest of the innovator companies to grow  their business.

Lack of transparency in drug trials data and consequences:

Outside pharmaceutical marketing, some of the biggest scandals in the drug industry have been alleged hiding of data related to negative findings in drug Clinical Trials (CTs) by the innovator companies.

Many stakeholders have already expressed their uneasiness on this wide spread allegation that research based pharmaceutical companies publish just a fraction of their CT data and keep much of the drug safety related information to themselves. Not too distant withdrawals of blockbuster drugs like Vioxx (Merck) and Avandia (GSK) will vindicate this point.

Examples of global withdrawals of drugs, including blockbuster ones, available from various publications, are as follows.

Questionable efficacy for the treatment of sepsis

A recent example:

A recent report indicates that Japan (Tokyo) based Jikei University School of Medicine plans to withdraw a paper on the hypertension drug Diovan of Novartis from the prestigious British Medical Journal (BMJ) due to “data manipulation,” suggesting the drug could help treating other ailments.

The report also indicates that an investigative panel formed by the university to look into the allegations of ‘rigged data’ for Diovan concluded that the results were cooked.

The decision of the Japanese University to withdraw this paper is expected to hurt the reputation of Novartis Pharma AG and at the same time raise ethical concerns about the company’s behavior concerning its best-selling hypertension drug, the report says.

Drug regulators contemplating remedial measures:

Now being cognizant about this practice, some drug regulators in the developed world have exhibited their keenness to disband such practices. These ‘gatekeepers’ of drug efficacy and safety are now contemplating to get the entire published CT data reanalyzed by the independent experts to have a tight leash on selective claims by the concerned pharma companies.

A review reportedly estimates that only half of all CTs were published in full and that positive results are twice as likely to be published than negative ones.

Recently the European Medicines Agency (EMA) has published a draft report for public consideration on greater openness of CT data. As stated above, this proposal allows independent experts to conduct a detail analysis on the safety and effectiveness of new drugs.

Mobilizing patients to thwart transparency?

Interestingly, as stated in the beginning, it has recently been reported that to thwart the above move of the drug regulator in favor of patients’ interest:

“The pharmaceutical industry has mobilized an army of patient groups to lobby against plans to force companies to publish secret documents on drugs trials.”

The same report highlights that two large overseas trade associations had worked out a grand strategy, which is initially targeted at Europe. This is for the obvious reason that the EMA wants to publish all of the clinical study reports that drug companies have filed, and where negotiations around the CT directive could force drug companies to publish all CT results in a public database.

Embroiled in controversy:

It has also been reported simultaneously, “Some who oppose full disclosure of data fear that publishing the information could reveal trade secrets, put patient privacy at risk, and be distorted by scientists’ own conflicts of interest.”

Pharmaceutical trade associations in the west strongly argue in favor of the need of innovator companies to keep most of CT data proprietary for competitive reasons. They reiterate that companies would never invest so much of time and money for new drug development, if someone could easily copy the innovative work during the patent life of the product.

However, the report also states, “While many of these concerns are valid, critics say they can be addressed, and that openness is far more important for patients’ drug safety reasons.“

Addressing the concerns:

To address the above concerns the EMA has reportedly separated clinical data into three categories:

  • Commercially confidential information.
  • Open-access data that doesn’t contain patients’ personal information.
  • Controlled-access data that will only be granted after the requester has fulfilled a number of requirements, including signing of a data-sharing agreement.

However experts do also reiterate, “Risks regarding data privacy and irresponsible use cannot be totally eliminated, and it will be a challenge to accommodate diverse expectations across the scientific and medical community. However, the opportunity to benefit the health of individuals and the public must outweigh these concerns.”

Some laudable responses:

Amidst mega attempts to thwart the move of EMA towards CT data transparency surreptitiously, there are some refreshingly good examples in this area, quite rare though, as follows:

  • As revealed by media, GlaxoSmithKline (GSK) has recently announced that it would share detailed data from all global clinical trials conducted since 2007, which was later extended to all products since 2000. This means sharing more than 1,000 CTs involving more than 90 drugs. More recently, to further increase transparency in how it reports drug-study results, GSK reportedly has decided to disclose more individual patient data from its CTs. GSK has also announced that qualified researchers can request access to findings on individual patients whose identities are concealed and confidentiality protected.The company would double the number of studies to 400 available by end 2013 to researchers seeking data of approved medicines and of therapies that have been terminated from development.
  • Recently Canada reportedly announced the launch of Canadian Government’s new public database of Health Canada-authorized drug CTs. It is believed that providing access to a central database of clinical trials is an initial step that will help fill an existing information gap as the government works to further increase transparency around CTs.
  • The well-known British Medical Journal (BMJ) in one of its editorials has already announced, “BMJ will require authors to commit to supplying anonymised patient level data on reasonable request from 2013.”

All these are indeed laudable initiatives in terms of ensuring long term drug safety and efficacy for the patients.

Conclusion:

It is quite refreshing to note that a new paradigm is emerging in the arena of CT data transparency, for long-term health interest of patients, despite strong resistance from powerful pharmaceutical trade bodies, as reported in the international media. This paradigm shift is apparently being spearheaded by Europe and Canada among the countries, the global pharma major GSK and the medical Journal BMJ.

A doubt still keeps lingering on whether or not independent expert panels will indeed be given access to relevant CT data for meaningful impartial reviews of new drugs, as the issue, in all probability, would increasingly be made to get embroiled in further controversy.

Moreover, if the innovator companies’ often repeated public stand – “patients’ interest for drug efficacy and safety is supreme” is taken in its face value, the veiled attempt of thwarting transparency of CT Data, with an utterly bizarre strategy, by the lobbyists of the same ‘patient caring’ constituent, can indeed be construed as a poignant moment, now frozen in time, in the history of drug development for mankind.

Be that as it may, to resolve this problem meaningfully and decisively, I reckon, a middle path needs to be carefully charted out between reported thwarting moves by pharma lobbyists and the embroiled controversy on the burning issue.

Thus, the final critical point to ponder:

Would the commerce-driven and cost-intensive pharma innovation also not be in jeopardy, affecting patients’ interest too, if the genuine concerns of the innovator companies over ‘CT Data Protection’ are totally wished away?

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

Posted on by
Reply

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.

A 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?

Beyond ‘The Magic Moment’ of New Drug Marketing Approval

Posted on by

“Uncontrolled clinical trials are causing havoc to human life. There are so many legal and ethical issues involved with clinical trials and the government has not done anything so far.”

This is exactly what the Supreme Court of India observed while responding to a Public Interest Litigation (PIL) on the subject in January 2013.

While Indian regulators with the active intervention of the Supreme Court are trying to grapple with, besides others, the basic ‘human rights’ aspect of the Clinical Trial (CT), many countries in different parts of the world are moving much ahead at a brisker pace. They have started thinking and putting in place more patient centric newer drug approval systems and also, in tandem, hastening the process of bringing new drugs to the market.

Current general scenario in CT:

Currently, after pre-clinical studies and before applying for regulatory approval, a new drug has to be tested on volunteers in randomized studies to prove its efficacy and safety on patients. Relatively short duration of new drug trials can hardly establish long-term safety and efficacy, which are now arrived at through extrapolation of data collected during CT period.

It is worth noting, the overall situation changes dramatically after launch of these products, as their usage expands from a relatively smaller number of CT volunteers to millions of real-world patients.

In a situation like this, unrealistic expectation of patients’ safety in perpetuity based primarily on extrapolation of very limited CT data is being increasingly questioned today.

That is why, on going post-marketing surveillance, which is also known as a Phase IV CT, is considered as a much more effective process to gauge relative superiority of the drug against the existing ones in terms of both efficacy and safety on a longer term.

That said, today one reads and hears umpteen number of accusations for almost lack of any meaningful response on the part of the pharmaceutical companies, in general, towards revelations of post-marketing surveillance data. This could, in turn, expose the patients to various types of risks, including wasteful healthcare expenditure.

The ‘Magic Moment’ in the present regulatory process:

A recent paper highlights a single “Magic Moment” between pre and post-licensing processes in the current drug-approval model in many countries. In this system, the use of a drug is tightly controlled in a narrowly defined pre-licensing population. Thus, CTs are also conducted on such pre-defined and relatively homogeneous volunteers, who are generally free from complicating conditions.

However, after ‘The Magic Moment’ of marketing approval, a large number of heterogeneous patient population, with many of them on multiple therapy, also use these new products in uncontrolled settings. Situations as these had led to post-marketing major drug withdrawals like, Vioxx and Avandia due to patients’ safety.

These grave concerns have led to a strategic shift in the drug regulatory approval scenario throwing open new ideas in the drug approval process.

Adaptive Licensing:

To find the right answer to this vexing issue the drug regulators in many countries are  reportedly seriously contemplating to imbibe a process that will continuously help analyzing information through ongoing post-marketing surveillance data. Continuous medical data analysis like this will enable the regulators to modify their earlier decisions on marketing approval and also medical reimbursements related to pricing reasons.

This new process is called ‘Adaptive Licensing (AL)’, which is expected to benefit the overall healthcare system, by not allowing medical reimbursement of treatments with those drugs, which will provide negligible benefit over existing low cost therapies.

Difference between current mechanism and AL:

According to a ‘Health Canada’ paper titled, “The Path to Adaptive Drug Regulation”, the difference between the two is as follows:

Current system:

As explained above, post-licensing i.e. after ‘The Magic Moment’ of regulatory approval, treatment population grows rapidly and treatment experiences do not contribute to evidence generation.

Adaptive Licensing:

After initial license, treated patients grow more slowly due to regulatory restrictions. Patient experience is captured to contribute to real-world information. The marketing license is also modified accordingly from time to time.

Most desirable for many drugs:

Experts in this field opine that AL will help bringing in alignment of all required processes so important for a new drug seen from patients’ perspective like, R&D, regulatory approval and market access with the active involvement of all stakeholders like, the pharmaceutical companies, the drug regulator, payors/insurance companies and also the researchers.

In the AL system, a transparent drug development process will provide enough data on risk-benefit profile of the concerned drug to satisfy the drug regulator for its quick marketing authorization on pre-determined types of patients.

Such approval will follow real-life monitoring of efficacy and safety for modification of the drug license accordingly, wherever and whenever required.

Thus, AL is expected to strike a right balance balance between timely access to new drugs for the patients and the need to evaluate real time evolving information on safety and efficacy leading to a well-informed patient centric decisions by the drug regulators.

A continuous regulatory evaluation and decision-making process:

AL intends to evaluate a drug through its entire life span.  It has been reported that during this long period, clinical and other data will “Continue to be generated on the product through various modalities, including active surveillance and additional studies after initial and full licensing. The artificial dichotomy of pre vs. post licensing stages (‘The Magic Moment’) will be replaced by graded, more tightly managed, but more timely and potentially more cost-effective market entry and market stability.”

Not necessary for all drugs in the near term:

It is worth noting that AL system may not perhaps be required for all pharmaceutical or biologic products and will not totally replace the current system of drug licensing process, at least in the near term.

AL process may immediately be followed only for those products with a favorable risk-benefit drug profile as demonstrated in the initial data and there is a robust reason for early market entry of this drug to meet unmet needs, simultaneously with ongoing studies.

The ‘Magic Moment’ freezes in India…in perpetuity:

As per the Drugs and Cosmetics Act of India, after obtaining drug marketing approval from the regulators, concerned pharmaceutical companies are required to follow the pharmacovigilance system in the country to own the responsibility and liability of the drugs as enunciated in the Schedule Y of the Act. Unfortunately, this is hardly being followed in India, ignoring patients’ safety blatantly.

With the plea that most products launched in India are already being marketed in many developed markets of the world, the concerned companies prefer to depend on clinical experiences in those markets. This attitude totally bypasses the regulatory requirement to follow a robust pharmacovigilance system in India. Indian drug regulators also do not seem to be much concerned about this important patients’ safety related requirements, very surprisingly not even for biosimilar drugs.

However, the current ground realities are quite different. As we witness today, there does not seem to be much difference in time between international and India launch of innovative products. Thus, the argument of gaining medium to long-term experience on safety and efficacy from international data related to these drugs, does not seem to hold any water at all.

On the contrary, some drugs withdrawn from the international markets on safety grounds are still available in India, despite ire and severe indictment even from the Indian Parliamentary Standing Committee.

In a situation like this, AL process of Marketing approval for selected newer and innovative drugs may be considered by the Indian Drug Regulators, just not to be more patient centric, but also to help evaluating  pricing decisions of innovative drugs failing to demonstrate significantly better treatment outcomes as compared to the existing ones.

A recent example of AL:

One of the latest drugs, which reportedly will undergo such regulatory scrutiny of USFDA is Tacfidera (dimethyl fumarate) used for the treatment of multiple sclerosis, approved in April 2013 and costing US$ 54,900 per patient per year.  Interestingly, Tacfidera, before the drug can find itself on a formulary, will need to demonstrate its effectiveness in the real world.

The report indicates, “the first six months after a drug launch are always about educating payers about its benefits, and while most large payers are likely to make a decision to reimburse the drug in the next twelve months, data collection will continue and changes in policies might be made at a later date.”

Thus, in the years ahead, whether a new drug will become a blockbuster or not will very largely be decided by the ongoing real world data. If the promise of a drug diminishes at any point of time through clinical data, it will certainly going to have consequential financial and other adverse impacts.

Another interesting recent development:

Under new pharmacovigilance legislation in Europe, the European Medicines Agency has reportedly announced the list of over 100 drugs that soon will bear the “black triangle” logo. This initiative is directed to encourage both the doctors and patients to report side effects to enable close monitoring of drug safety.

Criteria to include drugs under additional monitoring are:

  • Medicines authorized after January 1, 2011 that contain a new active substance.
  • Biologics for which there is limited post-marketing experience.
  • Medicines with a conditional approval or approved under exceptional circumstances.
  • Medicines for which the marketing-authorization holder is required to carry out a post-authorization safety study (PASS).
  • Other medicines can also be placed under additional monitoring, based on a recommendation from the European Medicines Agency’s Pharmacovigilance Risk Assessment Committee (PRAC).

Conclusion:

Global regulatory experts do believe that in the concept of AL, there are still some loose knots to be tightened expeditiously to make it a fully implementable common drug marketing authorization process.  Appropriate pilot projects need to be undertaken in this area to establish beyond any doubt that AL will be decisively more preferable to the current regulatory process.

As and when AL will become the preferred drug-licensing pathway across the world, it is expected to offer greater real benefits of new drug development to the patients for their optimal use at an affordable price.

That said, some other experts do opine as follows:

“No matter how fast the authorization process operates, the merits of innovation will not be felt until they reach patients. And the barrier between authorization and patient access remains, in most of Europe, the issue of reimbursement.”

While all these are fast developing in the global CT scenario, in the jangle of Clinical Trials‘ in India, ‘Adaptive Licensing’ has still remained a critical missing ingredient even to encourage a wider debate.
