Combating Covid Pandemic: When ‘Something Is Better Than Nothing’

Combating Covid Pandemic: When ‘Something Is Better Than Nothing’ 

As the new Coronavirus overwhelms the world, since its global outbreak, up until November 29, 2020, over 1,458,305 people have died from this pandemic. Understandably, the Governments in all countries are frantically searching for some robust remedial measures to prevent these unfortunate deaths, besides protecting livelihoods of a vast majority of people.

For this purpose, experts considered effective preventive measures, such as vaccines could help taming this menace, alongside existing personal prevention measures. Accordingly, scientists around the world, have are hard to accelerate development and manufacturing of safe and effective Covod-19 vaccines, within the prescribed guidelines. Equally important is the fact these vaccines must be safe with predictable effectiveness- for all age groups.

The good news is, vaccines are now a distinct possibility in the near future, with the positive interim Phase III clinical trial reports pouring in. It gets reflected in the remark of the Director General of the World Health Organization (WHO), on November 23, 2020, at the media briefing on Covid-19. He said: There is now real hope that vaccines – in combination with other tried and tested public health measures – will help to end the pandemic.

Interestingly, amid these reports, a lurking fear of many experts also surfaces – on the impact of possible side effects, that Covid vaccine may cause, besides their medium to long term efficacy in human subjects. But, with the mounting number of deaths, near collapse of the global economy, including India, there isn’t any more time to watch and wait.

Apparently, all governments now want some scientifically relevant vaccines, instead of nothing. This article will deliberate on the one hand – an unprecedented achievement, alongside some critical concerns – voiced even by the Indian Prime Minister. Let me begin with the apprehensions, as expressed by some domain experts on some rough edges, as it were, in the process of its development.

Queries on vaccine dosing, efficacy, safety and testing:

On November 23, 2020, AstraZeneca and Oxford reported interim results of their vaccine with the average efficacy of 70% prevention. This sounded good to many, as it falls within the expectations of above a 50% standard that the FDA had set for Covid vaccines. However, the puzzling part in this result was – bigger (standard) doses of the vaccines were less efficacious. The vaccine was only 62% effective in a group that got two full doses spaced about a month apart. But among about 2,700 people who got a half-dose followed by a full, the number rose to 90%, the report highlighted. This incident prompted several questions about the most effective dose of AstraZeneca and Oxford vaccine, including its safety record and the approach to testing. Consequently, apprehensions surfaced whether the Drug regulators will clear it, based on the currently available data.

It now appears, AstraZeneca ‘s Covid-19 vaccine is ‘headed for an additional global trial as the drug maker tries to clear up the uncertainty and confusion surrounding favorable results in its current study.’ Incidentally, in India - AstraZeneca and Oxford vaccine will be manufactured by Pune-based Serum Institute of India (SII) under a collaborative arrangement. Let me now dwell on a broader as aspect in this space.

Could current Covid vaccines become useless in the future?

There isn’t an iota of doubt that developing Covid vaccine in ten months, which otherwise takes around ten years – is an unprecedented achievement. However, there are several other important areas in this space, where pundits have expressed uneasiness through various articles.

Create Greater Patient–Value To Excel With Repurposed Covid Brands

Create Greater Patient–Value To Excel With Repurposed Covid Brands 

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.’...continue reading at https://bit.ly/35UmDiq

Covid Vaccine Challenges – Abidance To Defined Health Norms Stays As Lifeguard

Covid Vaccine Challenges – Abidance To Defined Health Norms Stays As Lifeguard 

here isn’t even a shade of doubt today that Covid-vaccines are coming. However, some critical questions in this area continue to hang in the air, and are expected to remain so for some more time. Thus, every news on the development of Covid vaccines, particularly in their late stages of clinical trials, fuels billions of hopes and excitement, across the world.

The same thing happened, when Pfizer and BioNTech announced on November 09, 2020, some key details on their vaccine candidate. These include, ‘vaccine candidate was found to be more than 90% effective in preventing COVID-19 in participants without evidence of prior SARS-CoV-2 infection in the first interim efficacy analysis’ from Phase 3 studies. The release also highlighted, ‘Submission for Emergency Use Authorization (EUA) to the U.S. Food and Drug Administration (FDA) planned for soon after the required safety milestone is achieved, which is currently expected to occur in the third week of November.’

Amid these new developments, it is also now beyond doubt that the pandemic will be brought under control, eventually. Interestingly, none possibly knows when it will happen. There doesn’t seem to be any clearly charted – time-bound pathway in place for the same, either – not just yet. That said, from the overall developments in this area for the past 10 months, especially in India, – two other crucial questions also remain elusive, as follows:

• Has the country started preparing itself against any Covid-like future biological threats? If so, in what manner?
• As India conducts the world’s largest  Universal Immunization Program (UIP), how robust is the country’s vaccine supply chain to effectively inoculate every Indian with Covid-vaccine?

I have already deliberated on several aspects of the former question in one of my previous articles, in this write-up. Therefore, this write-up will focus on the second query, with a specific reference to the continued relevance of abidance of the defined health norms for some more time, especially for my pharma industry readers. Accordingly, all astute pharma professionals in India, need to accept this new reality, and rewrite their brand demand generation strategies for the new normal. Let me start with how the cold-chain logistics for vaccines, in general, work in the country.

The cold-chain logistics for vaccines:

A paper published by the BBC News, on November 11, 2020, captured how the cold-chain logistics for vaccines, in general, work almost in all countries, including India. The article is titled, ‘Coronavirus: How soon can we expect a working vaccine?’ The steps involved in this exercise are as follows:

1. Vaccines transported to destination countries (imported varieties).
2. Refrigerated trucks for transportation to designated cold rooms.
3. Distribution in portable and appropriate ice boxes to regional centers.
4. Stored in electric fridges between 2 degree to 10 degree Celsius (for most of the existing vaccines.)
5. Carried in portable and appropriate ice boxes to local venues for vaccination to individuals.

Associated challenges:

As the above paper highlighted, some important associated challenges in this space, which are mostly faced by the developing countries, like India, are as follows:

• Adding a new vaccine to the existing mix could pose huge logistical problems for those already facing a difficult environment.

• According to prescribed norms, all Vaccines in India requires a storage temperature in the range of +2 degree to +8 degree Celsius, except for Oral Polio Vaccine which need to be stored in the frozen state (-25 degree – 15 degree Celsius) at all stores except PHC/ CHC/Health post. The new vaccine ROTAVAC (116E rotavirus) by Bharat Biotech is being recommended to be stored at (-15 to -25 degree Celsius) till the intermediate stores and to be stored in the range of +2 degree to +8 degree Celsius at the last storage points like PHC/ CHC/Health posts. This has not posed much of a challenge. However, expanding it to cover the entire population of the country can be an “immense task.”

• It is worth noting, although, AstraZeneca vaccine would need the regular cold chain between 2C and 8C, the Pfizer and BioNTech vaccine would need ultra-cold chain – storage at around minus 70C to 80C.

• ‘Maintaining vaccines under cold chain is already one of the biggest challenges’ that countries face, and this will be exacerbated with the introduction of a new Covid vaccine.

• Thus, more cold chain equipment will require to be added, making sure that fuel is always available (to run the freezer and refrigerators in absence of electricity) and repair/replace them when they break and transport them wherever you need them.

Curiously, India’s cold-chain logistics that cater to one of the world’s largest immunization programs for children and mothers, may not be enough for Covid-19 vaccination of the country’s 1.3 billion population.

Why India’s cold-chain logistics may not be enough for Covid vaccination:

Before coming to the above question, it is important to note that India is not just the pharmacy of the world, contributing over 20 per cent by value to the global generics market, and over 40 per cent (by volume) of US drugs. According to a recent report of Bernstein Research, Indian vaccine producers, such as, Serum Institute of India supply the bulk – over 40% of the global capacity of 5.7 billion doses annually. Home to some of the world’s biggest vaccine makers, India produces 2.3 billion doses of vaccines yearly, with 74% for export, said...continue reading of Covid Vaccine Challenges – Abidance To Defined Health Norms Stays As Lifeguard https://bit.ly/2Iv2S8z

Creative Pharma Marketers To Unshackle Covid Fetters

 

Pharma industry, just as most others, has started recognizing that the business needs to be brought back to normal, despite Covid fetters. Some early evidences suggest, a new breed of pharma marketers is refusing to get confined to Covid triggered operational limits, without breaching any prescribed safety norms.

These pacesetters no longer grapple with finding right answers to the question – when and how the brand building activities can be brought back to the old normal? Truly speaking, none has its answer, as yet. Covid has the power to strike back, anytime – anywhere, in waves, when the guards are even slightly down. Moreover, as and when vaccines will come, these may not be ‘silver bullets’ for many – throughout a lifetime, at least, in the foreseeable future.

Accordingly, these forerunners are effectively leveraging the art of turning challenges into opportunities. They are conceptualizing new business models for making path-breaking progress in contemporary purpose driven branding exercises. For all pharma marketers, I reckon, this is the moment of truth, when what you do reflects what you really are, in this area. Thus, in this article. I shall deliberate, with examples, how these creative new age pharma marketers are trying to unshackle Covid fetters.

Today’s reality on the ground: 

A number of global surveys on how patients’ have reacted to Covid-19 pandemic with reasons behind the same, are now available. One such study was conducted by Medisafe, during March and April, 2020. Some of its key findings are as follows:

• More than half of the respondents, especially those with comorbidities, worry about getting Covid infected while accessing to in-person treatments.

• Over 9 out of 10 respondents were practicing social distancing, as a remedial measure.

• Consequently, they are missing doctors’ appointments, and many are opting for telehealth wherever appropriate and necessary.

In many situations, such as,  common and repetitive health issues, including some mental health conditions, virtual health care are more convenient. It has also been established during the pandemic that telehealth can deliver similar outcomes at a lower cost, than in-person visits. In addition, remote monitoring of some key health parameters, like heart rhythm, blood sugar, weight, respiratory rate, also help people control their chronic conditions better, and assist clinicians with diagnosis and treatment.

More doctors prefer telehealth, but the majority wants some in-person visits too: 

An interesting study – ‘Want Both In-Person and Virtual Visits with Sales Reps,’ published by Bain & Company on June 02, 2020, ferreted out today’s reality, in this space. It found, prior to Covid, about three-fourths of physicians preferred face-to-face engagement with sales reps. In contrast, today more of them are asking for a reduction in Rep visit frequency and more remote support or virtual approaches. Curiously, a majority still prefers, at least some in-person interaction ‘once the pandemic passes.’

Interestingly, no one seems to know, just yet, when exactly will this pandemic get over. Besides, whether or not Covid will keep coming back in waves, for an indefinite period. Or, any similar or even worse global health crisis, in future, could bring greater disruption for the industry.

Driven by such apprehensions, it is possible that more and more patients will prefer telehealth, expanding access to health care for an increasing number of people. Nonetheless, one should also take into consideration that virtual health care has also some significant limitations, especially those which may lead to serious or life-threatening conditions.

Some key limitations to overcome:

Alongside multiple advantages of telehealth, it has some significant limitations, which can’t be wished away, either. This point was also well articulated in the article – ‘Where Telemedicine Falls Short,’ published in the Harvard Business Review (HBR) on June 30, 2020. The author, who is also a primary care physician gave a number of examples in this regard. For example, in one place he wrote:

‘I have found treatable cancers multiple times in routine exams that would be impossible to replicate in the virtual world. Could a Zoom visit detect a lymph node too firm, a spleen or liver too large, or an unexpected prostate nodule (with a normal PSA)?’ The paper also emphasized: ‘Trust and face-to-face encounters are even more important for patients with complex and intertwined problems.’

Be that as it may, the task to encourage patients, even with serious ailments, for in-person consultation and examination by doctors’ in their clinics, won’t be ‘a piece of cake’ too. On the contrary, it will be rather a colossal exercise. .......Continue reading more of Creative Pharma Marketers To Unshackle Covid Fetters

India Being World’s Third largest Covid Vaccine Maker: Will All Indians Benefit?

India Being World’s Third largest Covid Vaccine Maker: Will All Indians Benefit?  

Apprehensions on the time of availability notwithstanding, equitable access to Covid vaccines for all, remain the best hope to leash the deadly virus, as the pandemic overwhelms the world. According to the World Health Organization (WHO) ‘Coronavirus Update 37’ of October 06, 2020, as of October 02, 2020, there are 42 COVID-19 candidate vaccines in clinical evaluation of which 10 in Phase III trials.

Recently, the article, published in the Harvard Business Review on April 02, 2020, also flagged this critical area – ‘A Covid-19 Vaccine Will Need Equitable, Global Distribution.’ The paper highlighted: ‘The time to prepare for globally distributing a Covid-19 vaccine in a way that is effective and equitable is now. It will have a long-term payoff by helping to prevent future pandemics, which scientists predict will be more common as the earth’s climate warms.’

Even Bill Gates’ article, published in The New England Journal of Medicine (NEJM) on February 28, 2020, expressed a similar apprehension. The article is titled - ‘Responding to Covid-19 – A Once-in-a-Century Pandemic?’ Gates also articulated: “During a pandemic, vaccines and antivirals can’t simply be sold to the highest bidder. They should be available and affordable for people who are at the heart of the outbreak and in greatest need. Not only is such distribution the right thing to do, it’s also the right strategy for short-circuiting transmission and preventing future pandemics.”

He too urged all concerned to ensure that during a pandemic, vaccines and antivirals aren’t ‘simply be sold to the highest bidder.’ On the contrary, these should be made available, affordable and accessible to all. ‘Not only is such distribution the right thing to do, it’s also the right strategy for short-circuiting transmission and preventing future pandemics,’ he asserted.

Does any authority pay heed to these suggestions? The question remains unanswered. Interestingly, on September 17, 2020 by a Press Release, Oxfam International reported, ‘leading wealthy nations representing just 13 percent of the world’s population have already cornered more than half (51 percent) of the promised doses of Covid-19 vaccine candidates.’ This is regardless of where these vaccines are manufactured, including India.

These prompt one to wonder, ‘Would India’s possible rise as the world’s third largest vaccine manufacturer benefit all Indians, with affordable and equitable access to Covid prevention shots? In this article, I shall dwell in this area.

India emerges as the world’s third largest Covid vaccine producer:

According to August 24, 2020 edition of the Nature publication, if all of the frontrunner candidates of Covid vaccines are approved, more than 10 billion doses could be available by the end of 2021. Most of these vaccines will be made in the North America and Europe. The top Covid vaccine manufacturing countries are estimated to be the United States, followed by the United Kingdom, India, Norway and France, the report highlights.

However, wealthy countries have already struck deals to buy more than two billion doses of Coronavirus vaccine in a scramble that could leave limited supplies in the coming year. For example, as the above Nature article indicates, publicly announced estimated capacity to 2021 of Oxford/AstraZeneca Covid vaccine, is 2.94 billion. Interestingly Serum Institute of India (SII) signed an agreement to manufacture over I billion doses in 2021.

Whereas, another report of September 29, 2020, stated that SII will make available 200 million doses by 2021, at $3 dose to a group of at least 62 ‘low- and middle-income countries (LMIC)’ that includes India. This arrangement does not make clear how many of the 200 million doses will be made available in India. Curiously, SII reportedly, is also one of the global partners for the production of Britain’s Covid-19 vaccine on a large scale, once it gains regulatory approval.

Growing ‘vaccine nationalism’ needs to be prevented:

Thus, if one looks at the macro picture, a small group of rich nations, representing just 13 percent of the global population has bought 51 percent of the supply of leading Covid-19 vaccine contenders, according to the above Press Release of Oxfam International.

Many public health experts have expressed grave concern on such developments. They have also articulated in multiple forums that the world is not going to get rid of the pandemic until it gets rid of Covid-19 from everywhere. Terming this approach vaccine nationalism, the Director General of the World Health Organization (WHO) urged all concerned, at his August 18, 2020 briefing that this needs to be prevented by all, urgently.

No clarity yet, on whether the vaccine will be free for all Indians:

Although, there is no reported ‘vaccine nationalism’ in India, thus far, for understandable reasons, there isn’t any clarity, either, on whether Covid vaccines will be free for equitable access to all in India. As reported on October 27, 2020,...continue reading at https://bit.ly/2HSlO08
