Data Integrity Issue Haunts Again With Covid Vaccine?

Posted on by

On March 22, 2021, by a media release, AstraZeneca announced that its ‘US Phase III trial of AZD1222 demonstrated statistically significant vaccine efficacy of 79% in preventing symptomatic COVID-19 and 100% efficacy at preventing severe disease and hospitalization.’

Quite unexpectedly, on March 23, 2021, the above claim on AstraZeneca’s Covid-19 vaccine, triggered a rare post-midnight statement by the National Institute of Allergy and Infectious Diseases (NIAID) of the United states. It rekindled a lurking fear of many, yet again, on the issue of questionable data integrity within the drug industry, in general.

This News Release articulated: “Late Monday, the Data and Safety Monitoring Board (DSMB) notified NIAID, BARDA, and AstraZeneca that it was concerned by information released by AstraZeneca on initial data from its COVID-19 vaccine clinical trial.”

The concern was on the possible inclusion of outdated information from that trial, ‘which may have provided an incomplete view of the efficacy data.’ It urged AstraZeneca to work with the DSMB to review the efficacy data and ensure the most accurate, up-to-date efficacy data be made public as soon as possible.

Later on that very day, AstraZeneca released another statement saying: “The numbers published yesterday were based on a pre-specified interim analysis with a data cutoff of 17 February. We have reviewed the preliminary assessment of the primary analysis and the results were consistent with the interim analysis. We are now completing the validation of the statistical analysis.”

The company further emphasized, “We will immediately engage with the independent data safety monitoring board (DSMB) to share our primary analysis with the most up to date efficacy data.” And also added that AstraZeneca intends to issue the results of the primary analysis within 48 hours.

However, the impact of the NIAID’s announcement on the unfurling of AstraZeneca’s Covid-19 vaccine in the U.S, is yet to be ascertained. It’s also still unknown what this news could mean for the vaccine’s alleged efficacy. Be that as it may, it all happened at a time when millions of people, in many countries of the world, including India, have already taken, at least, the first dose of this vaccine.

In this article, I shall deliberate on broader aspects of this critical issue and its relevance in the present case. However, before doing so, let’s try to figure out, why data integrity still remains a major concern of many experts in this area.

Why data integrity is still a major issue:

There are many studies that raised serious concern in this area, over a period of time. For example – ‘Dozens of recent clinical trials may contain wrong or falsified data’ – was claimed by the research paper that was discussed in ‘The Guardian’ on June 05, 2017.

This study reviewed data from 5,087 clinical trials, published during the past 15 years, in two prestigious medical journals – JAMA and the New England Journal of Medicine, and six anesthesia journals. In total, 90 published trials had underlying statistical patterns that were unlikely to appear by chance (or be termed as ‘unforced error’) in a credible dataset, the paper concluded.

Even my own article of September 30, 2019 deliberated on various facets of ‘data integrity’ involving novel therapy, across the world. There, I quoted one of the top medical experts related to the above paper, saying: “It’s very scary that we may be treating patients based on false evidence.” He further added: “It may be the case that certain treatments may need to be withdrawn from use.”

The ghost of a recent example still haunts:

Not so long ago, much reported fallout from Novartis’ alleged data manipulation fiasco with its billion-dollar gene therapy Zolgensma, shook all concerned. So much so, that the Company CEO had to pledge during an investor conference that: ‘the company will be more proactive in reporting data integrity issues to the FDA.’

He also added, Novartis has responded to the FDA’s Form 483 and is making documents available as requested, while reiterating that the data manipulation uncovered at the San Diego site “does not impact the safety, efficacy or quality of Zolgensma.”

The key point to ponder, therefore, especially in AstraZeneca’s Covid-19 vaccine case – is the same ghost haunting us, yet again?

Is it happening again? 

One may, possibly, find some cue of the answer to this question while looking at what followed after ‘validation of the statistical analysis’ by AstraZeneca, as it was promised by the company. Interestingly, the following day, after apparently a thorough analysis, the data released by AstraZeneca, re-iterated effectiveness of its COVID-19 vaccine, which apparently, is broadly similar to the results released earlier.

The Company highlighted therein, ‘US Phase III primary analysis confirms safety and efficacy,’ with the following points:

  • 76% (earlier shown as 79%) vaccine efficacy against symptomatic COVID-19
  • 100% efficacy against severe or critical disease and hospitalization
  • 85% efficacy against symptomatic COVID-19 in participants aged 65 years and over.

It may continue to remain unclear to many – whether or not there was some suspected issue of data integrity – till the answers, at least, to the following questions are made public:

  • Why did the data and safety monitoring board for the trial write a harsh letter to AstraZeneca on its claim, and copied the leadership of NIAID and the Biomedical Advanced Research and Development Authority?
  • As the proof of the pudding is in its eating, why there will even be a slight downward revision in the rate of efficacy of AstraZeneca Covid-19 vaccine?

Conclusion:

I wrote in this blog, way back on August 03, 2015 that data manipulation issues are dangerously leapfrogging into clinical trial domain, even in India. As a result, many domestic drug players had to pay a heavy price – in terms of drug import bans by USFDA and other regulators. Several questions on the quality of efficacy and safety of Indian generic drugs were also raised in many developed countries. A number of best-selling books were also written on this issue.

Some may recall, just ahead Covid pandemic struck, trial data of a highly complex and very expensive gene therapy was also questioned by the US-FDA, for the same reason. However, on March 31, 2020, on completion of its review of the information, records of the inspection, the evidence collected, and the firm’s corrective actions, US-FDA stated: “Objectionable conditions were found and documented but the objectionable conditions observed during the inspection do not meet the threshold for regulatory action.”

Almost in a similar line, after the NIAID decided to make its data related concern public on AstraZeneca Covid-19 vaccine, its head, Anthony Fauci, reportedly, characterized this issue as “an unforced error.” This is indeed a cryptic comment. The root cause of this entire saga with details is still awaited.

Interestingly, the term “unforced error’ is widely used in Tennis, and means, ‘a mistake in play that is attributed to one’s own failure rather than to the skill or effort of one’s opponent.’ From this perspective, after AstraZeneca’s statement of clarification on its Covid-19 vaccine data, the concern on its phase three trial data would possibly be put to rest. At least for now, let’s not see the ghost of data integrity for this vaccine, where there doesn’t seem to be any.

Seeing ghosts where there aren’t any

Seeing ghosts almost everywhere in the Indian pharmaceutical industry, especially where there aren’t any, has indeed become quite common nowadays, across the spectrum of stakeholders. The ‘ghosts’ could well reside in ‘100% Foreign Direct Investments (FDI) through automatic route in the pharmaceutical sector’ or ‘threat to the generic industry of the country by the MNCs’ or ‘abysmal Intellectual Property environment vitiating investment climate of the global players’ or even presence of ‘invisible foreign hands’ in shaping important policies of the country, just to name a few.

“Seeing ghosts”: Both from inside and outside the country:

The incidence of encountering with ‘ghosts’, from both inside and outside the country, would possibly increase further as the economic attractiveness of India in general and pharmaceutical consumption in the country in particular, will keep growing fast in the years ahead.

India attracting:

Currently McKinsey & Company in its report titled, “India Pharma 2020: Propelling access and acceptance, realizing true potential”, estimates that the Indian Pharmaceuticals Market (IPM) will record a turnover of US$ 55 billion in 2020 from around US$ 12.1 billion in 2011. The report further highlights that with aggressive growth boosters it is quite possible to make the IPM attain a turnover of US $70 billion during the same period. Rapid urbanization, increasing accessibility to drugs due to expansion of healthcare infrastructure, fast growing rural markets, increasing resource allocation to public health, patented products, consumer healthcare, biologics and vaccines will be the key growth drivers for the industry.

The burning issue of affordability for healthcare is expected to be addressed by 650 million people coming under health insurance and additional 73 million people getting added to middle and upper class segments by 2020.

All ‘ghost’ seeing are not unjustifiable:

In this evolving scenario, ‘encounter with ghosts’ in some areas may perhaps be justifiable, especially, within the country. Commensurate justifiable measures will require to be put in place to allay those justifiable fears.

Recent India visit of two global iconoclasts:

However, last week, when India witnessed visits of two global CEOs of two global pharmaceutical majors, Andrew Witty of GlaxoSmithKline (GSK) and Chris Viehbacher of Sanofi, from the media reports it appeared to me  that we are made to see ‘ghosts’ in some of the key areas of the Indian Pharmaceutical Industry, where there aren’t infact any. As per media reports, both Witty and Viehbacher, who are also Chairpersons of the European Federation of Pharmaceutical Industries and Associations (EFPIA) and the Pharmaceutical Research and Manufacturers of America (PhRMA), respectively, articulated great commitments of their respective companies to India by aligning their business goals with the national healthcare policy and objectives of the country.

Long term commitment to India:

 

Last year Andrew Witty dedicated the new Albendazole manufacturing facility of GSK at Nashik in India to the ‘Global Program Filariasis’ to the ‘World Health Organization (WHO)’ being the largest drug donation program in the history of global pharmaceutical industry.

Early October this year during his visit to Mumbai, Witty reiterated in unequivocal terms that the cost of around US$ 2 billion to innovate and develop a successful drug is unacceptable to him as it includes to a large extent the cost of failure in that endeavor.  “We need to fail less often and succeed more often”, he said while emphasizing that the global pharmaceutical industry needs to metamorphose and must learn to strike a right balance between the cost of R&D projects and delivering innovative medicines to the patients at affordable prices.

Witty also mentioned that GSK globally follows a tiered pricing strategy, linked to the economic conditions of the individual countries. He feels that pharmaceutical product price should be commensurate to per capita income of a nation.

Without any hesitation Andrew Witty said that India will be one of the most prominent markets among the emerging economies that the global drug makers are concentrating now.

Closely followed by Andrew Witty’s visit to India, another iconoclast Christopher A Viehbacher, global CEO of Sanofi stepped into our soil and announced that Sanofi will invest US$ 300 million in a “state-of-the-art” manufacturing plant and R&D initiatives of Shantha Biotechnics in Hyderabad to make it the biggest vaccine plant of Asia not only to cater to the needs of India, but also to reach affordable vaccines across the globe.

Viehbacher emphasized that Sanofi wants to continue to build its long term business in India because of its market attractiveness. Like Witty, he emphasized that Sanofi strategy is also to have affordable medicines in emerging markets like India so that people can afford to pay for.

He reportedly reiterated, “I do not want us to be a colonial company with a colonial approach where we say we decide on the strategy and pricing. If you have to compete locally then the pricing strategy cannot be decided in Paris but will have to be in the marketplace. People here will decide on the pricing strategy and we have to develop a range of products for it”.

Viehbacher feels that emerging markets including India are expected to account for 40% sales of Sanofi by 2015.

Conclusion:

October 2011 India visit of these two visionaries of the global pharmaceutical industry, reinforced the fact that in many areas of the Indian Pharma sector we fancy to see “Ghosts where there aren’t any”, just as it happens outside the shores of India with equal intensity, gusto and zest.
