Leucine Rich Bio - what a journey!

 

I feel nostalgic and proud of the journey that we started 8 years ago with the very humble and passionate team at Leucine rich Bio. I remember starting out with a basic computer and few exceptional colleagues with a vision to bring in a new paradigm shift in life science and healthcare domains.

 

The first few years went by doing research projects with marquee institutes, companies and universities from across the world. Our strength lied in the cross-sectional abilities of systems biology, bioinformatics, molecular biology. We completed complicated genomics projects for our esteemed clients and in turn gained lot of insights into the various domains. In Parallel, we started building the base of the hitherto new concept called the “microbiome”. This was 2016 and microbiome was a very new concept with a handful of companies in the world. We created patent pending algorithms, in-house curated databases and decision engines and set out on a mission to bring this new science to this region (South Asia). Initial few months went into beta testing of the product. We got lot of feedback on the report. As this was first of its kind report, we did not have a yardstick to compare our report with, so we started putting “actionable” information as per the feedback of the people. This is how “BugSpeaks”, South Asia’s first gut microbiome test was launched. It was a challenge to say the least to bring in a nascent field to India and create awareness among the stake holders. Also, challenging was the cost factor as the technology that we were using, next generation sequencing was quite expensive. However, we got the support of visionary family house investors (Omphalos ventures, Bengaluru) who believed in our vision and supported us all the way till today.

 

Covid19 stuck us all. But we tried to utilize the downtime by doing research and our first research review paper was published in a peer reviewed scientific journal, Virus Research. This was the first paper to suggest the possible link of SARS-Cov-2 virus with the gut microbiota. This opened lot of scientific collaborations and joint research work. In fact, Leucine Rich Bio is partnering with various companies/Institutes in clinical trials addressing the gut/oral microbiota.

We have also started our own clinical trial on efficacy of Bugspeaks (patient recruitment over and intervention is ongoing) and few more trials are on the anvil.

 Along the way, we started getting feedback about the report and that led us to develop South Asia’s first gut microbiome data-based nutraceutical product line called “Rychbiome”. Our first product is a synbiotic called “Rychbiome Indus” which was derived using Indian gut microbiome data (internal). We hope to bring in new products in this category addressing various conditions as we move along.

 

The feather on our cap was when we were declared the National start up winner (2021) by Government of India in the life science category, sub category – wellness in a highly competitive background. We were recently invited by the national broadcaster, Doordarshan for the series “startupchampions 2.0”. We have started exporting BugSpeaks to Thailand and export to a few more countries are in the pipeline.

 

Now, “microbiome” has become a buzz word in the industry. We feel proud of the fact that we have been a pioneer and a trendsetter. With frugal means we could achieve a lot and we envision to see Leucine Rich Bio and its products BugSpeaks and Rychbiome scale new heights. There are a lot of products and new applications of the microbiome that we have planned for. These last 8 years were full of learnings, sacrifices, test of patience and perseverance. We thank all our clients, investors, partners and well wishers for their support. A big THANK YOU!

Microbiome Domain – A journey and perspective from India

 

Our journey in the microbiome domain started in 2015. We had launched our company, Leucine Rich Bio pvt ltd. in the Silicon Valley of India, Bengaluru in the late half of 2014. We integrated our expertise in genomics, systems biology, molecular biology, information technology and bioinformatics to build a robust system that could address the challenges of the microbiome domain. We curated tons of research papers to build our own databases (Microbyte and Nutribyte) which contained information on the various aspects of the microbiota, their link to diseases, nutrients in food etc. Next challenge was to develop algorithms and matrices that would take the raw data from next generation sequencing machines as input and provide an actionable output in the form of a report utilizing the data from our in-house databases. That’s how South Asia’s first microbiome test, BugSpeaks was launched in mid-2018. Also, in early 2021, we launched India’s first gut microbiome data-based nutraceutical line, Rychbiome. It gives us immense pride that we could become this region’s first microbiome company and in doing so also helped spread awareness on this very important aspect.

So, what have been our challenges? Well, microbiome domain is very complicated and it required a great mix of expertise from various quarters to pull this off. Running a deep science based startup in India has its challenges. Although in the last few years the startup ecosystem has evolved yet it has still miles to go for it to become mature like in the West. Then there was lack of awareness as this domain was new. Interestingly, people in general, in India know a lot about the importance of gut health as our ancient scriptures like Ayurveda emphasized on keeping the gut healthy. Most people in India eat a variety of fermented foods as part of their routine diet thereby taking care of their gut! however, the fact that one can now profile one’s gut microflora and based on that could take certain actionable steps to improve their health and wellness was very new to them. We also found a lack of interest from majority of the investment community in India. This may be again because this field was new and there were no yardsticks to compare us with. But I feel now things are changing and I hope investors in India can see the potential of this domain and how it can change the way healthcare functions!

So, what are the advantages that we have? First, India is very diverse. The gene pool, the food habits, the climate, everything adds tremendous value to the microbiome data. Secondly, India is rich source of skilled and talented workforce. We are already an IT major and we have tremendous skilled force in the biotechnology and life-science domains as well. Such combination is hard to find by and expensive in other parts of the world. 

Where do we see the microbiome space going? We feel this domain can revolutionize the healthcare paradigm. Currently it is more commonly associated with the wellness category but it has the potential to provide diagnostic, prognostic and therapeutic solutions in gastroenterology, oncology, mental health and women health!

We feel India is in the cusp of providing major breakthroughs in various fields and microbiome domain is no different provided the government and investor community support this space!

A new revolution in Life Science and Healthcare called “Microbiome”

Any new development in life science and healthcare starts with baby steps and slowly but surely takes the world by storm. Whether it is small molecule based, high-end genomics guided targeted cancer therapy or the immuno-checkpoint inhibitors which are taking cancer treatment to the next level of personalization and precision.

In the last decade one small buzz word has created quite a noise and is bringing hope that indeed wellness and personalized treatment is a possibility – enter the world of the “microbiome”. The term microbiome means the entire genome of the microbiota ecosystem. The advent of microbiome research parallels the advancement in next generation sequencing (NGS). Before NGS came into the picture, microbiology-based study could rely only on culturing microorganisms in the lab which had its own drawbacks. Now, with advanced sequencing technologies and smart algorithms it is possible to dissect the microbial ecosystem without the need to culture microorganisms in the lab.

Human intestine harbors the maximum number of commensal organisms which are into a delicate relationship with the host. It is therefore not a surprise that maximum gut microbiota based studies are published which look into how gut microbiota plays an important role in human health and wellness.

Do you know:-

Ø   Metagenomic sequencing of fecal samples has identified 3.3 × 10⁶ nonredundant  microbial genes from up to 1,150 different species, outnumbering human protein-coding genes by about 150-fold

Ø     Each person is estimated to host at least 160 different species 

Ø  In 2007, only 14 NIH grants contained the word “microbiome” in their titles or abstracts, and the number went up to 1,043 in 2017

Ø   More than 10000 papers published in the last 3 years on “gut microbiota”

With new studies and developments in the gut microbiome space, it would suffice to say-

“If eyes are the windows to the soul, then gut microbiome is the window to your health”

The industry has also taken a leaf and are dwelling into various aspects of the microbiome space. Companies like Leucine Rich Bio (India), Day Two (Israel), Viome (USA), UBiome (USA), Microba (Australia) etc. are taking the developments in the research to consumers directly by providing easy to use at home gut health tests. And there are companies like Enterome (France), Vedanta Bioscience (USA), Seres Therapeutics (USA) etc. that are looking into tapping the therapeutic potential of the microbiome and thus bringing new paradigms in treatment of various type of cancer, IBD, IBS etc.

Investors especially in the Western world have and are putting lot of faith in these new age companies. Most notably Seventure Partners that have funded a slew of microbiome companies in Europe and the US.

Although, lot many research and studies will be needed in future to validate the interesting leads that the microbiome domain throws up yet it is pertinent that all stakeholders especially clinicians and investors in Asia also support this with less skepticism and more openness as the success of the microbiome can lead to a new era of healthcare and wellness

 

"StartUp” but hold tight

“Startups” in today’s day and age can provide two important deliverables to the society: -

·       Employment

·       Innovation and possible disruption in the domain they are active in

No doubt Governments across the world and more specifically here in India are trying to support start-ups. However, for entrepreneurs, it is a long winding road that they need to traverse to see light at the end of the tunnel. Not all ideas can be commercialized immediately especially if it is highly technical and demand lot of testing and “proof of concept” studies.

Even after successfully achieving that comes the challenge of proper marketing and positioning of the product. All of these take time and therefore it is imperative that all stake-holders in the “startup” including employees and investors hold tight and pursue with perseverance.

Startups in the life science domain have their own challenges apart from the regular ones. The “bench to bedside” concept which the domain especially pharma and biotech works on relies heavily on research. Now, this type of research primarily is based on pre-clinical and then clinical studies. We all know how long it takes for a particular concept to cross all the stages till it reaches the end user. Therefore, patience is an inbuilt asset for the startups that are in this domain. Many startups in US and Europe start working on spinoffs from interesting leads that come out in a laboratory and many lucky ones get funded as well. However, this concept in India needs some time to catch up as investors are vary into putting money so early without any credible road to return of investment. Also, I feel if there are “success” stories in the life science space that come out of India then many investors will get enthused about funding this domain.

Having said that, not all life science startups need wait for the discoveries to take a credible shape. Many companies in the microbiome space for example like Viome (US), Ubiome (US), Day two (Israel) and Leucine Rich Bio (India) are already trying to bring the fruits of research faster to the end user. Of course, research is always “work in progress” and especially in life science new discoveries and theories can append to the existing knowledge however accelerating adoption is also key in making paradigm shifts in the domain.

Hence, it is very important to build an ecosystem where the startups can provide the necessary impetus to the society and all stake holders need to hold tight till the end result is achieved!

The lost war or is it? – Infections vs Antibiotics

Antibiotics, once hailed as magic bullets for battling infection are now facing serious challenge from their adversaries, the bacteria, which are hitting back with renewed vengeance. A recent case of a patient in New Zealand dying of bacterial infection (Klebsiella pneumonia) which was resistant to all known antibiotics points to an ‘apocalypse’ scenario in the future if corrective measures are not taken. 

So where is the problem? First, the tendency to overprescribe antibiotics for even slightest of infection is a big worry. Alexander Fleming, the father of antibiotics had warned of dangers of antibiotic resistance. In fact, Penicillin-resistant bacteria arrived while the drug was still being given to only a few patients. Another breeding ground for antibiotic resistant bacteria is in their rampant use in farm animals. Unfortunately, for the pharma companies research interest into antibiotics have slowly waned as there are far more profitable drugs to throw money at, since antibiotics are usually single-serve drugs for humans, not long-term treatments. Drugs for chronic conditions tend to be more profitable. And with drug resistance quickly evolving, rendering older antibiotics ineffective, pharma companies have even less incentive to invest in these drugs. However, recent trends suggest that big pharma companies might be reviewing their strategy as Roche has re-entered the arena through a $550 million tie-up with privately held Polyphor, a Swiss company, to develop and commercialize an experimental antibiotic against hospital superbugs. 

The key is to collaborate with Universities and small drug discovery companies that focus on infections as Roche did. Smaller companies are looking at next-generation drugs or in some cases alternative therapies. Some companies for example are looking at bacteriophage therapy. But despite technical successes, these companies face an uphill battle in developing a consistent, approvable product and haven't yet found much commercial validation or attracted much investment. This is where the experience and backing of big pharma companies would help. Another alternate and a newer area of interest is the human microbiome, which can lead to potential commercial therapeutics. Microbiome companies like Seres Health, Vedanta Biosciences and Second Genome are a good bet as far as making the next cut for coming out with a new approach to treating infections are concerned!

Gut Microbiome – Type 2 diabetes association; outcome and possibilities

The phrase ‘my gut feeling’ has got another scientific validation with some new metagenomics studies published recently. After all, it seems that the gut can dictate the potential well being of an individual. A case in point is the latest paper in Nature journal in which the researchers conducted a gut metagenomic study on Chinese patients suffering from type 2 diabetes (http://www.nature.com/nature/journal/vaop/ncurrent/full/nature11450.html). Gut microbiome has been in the forefront of research especially after the advent of the Next Generation Sequencing technology. Today, the advancement in the field of development of sequencers and sequencing technology is even challenging the Moore’s law.

Gut microbiome also being called as the “other genome” or human’s “second genome” is implicated in many of the chronic diseases/disorders like obesity, inflammatory bowel disease and even depression so it is natural that with the latest technology in hand the scientists would focus on this in a much more refined manner. The present study finds some interesting facts about the commensals in the gut of Chinese patients suffering from type 2 diabetes. Functional characterization showed that there was a decrease in the level of bacterial chemotaxis, flagellar assembly, butyrate biosynthesis and metabolism of cofactors and vitamins in the gut bacteria of these patients. The researchers also found markers that indicated that the gut environment of a T2Dpatient is one that stimulates bacterial defence mechanisms against oxidative stress. This might be interesting as previous studies have implicated high oxidative stress levels to pre-disposition to type 2 diabetes. Strikingly, the researchers found orthologue markers that suggest that these diabetic patients might have a hostile gut environment. The researchers also found that there is moderate gut bacteria dysbiosis and an increase in several opportunistic pathogens.

The above mentioned salient outcomes of the study raise many exciting questions and possibilities. Does the change in gut microbiome composition a cause or an effect of the disease? Scientists would be addressing this part next with some studies in animals. Can in the future the gut microbiome sequencing be used as a predictive tool? Can modulating the gut microbiome cure such diseases? Can effective research in pro-biotics now fill in the space and fulfill what modern medicines could not achieve so far?

This is a perfect example of how a 21^st century technology has ignited a fresh look at the association of the microbiome with the human health

Human microbiome – the new frontier in medicine?

‘Antibiotics heal but they also cause damage’- this adage is well known and now probably better understood. With the advent of Next Generation Sequencing (NGS), exploring the world of the micro organisms has become easier. And as they say, ‘truth is stranger than fiction’; the results of such studies are giving some startling facts about the bacteria that co-inhabit our bodies. Like each individual has a unique DNA or fingerprint, it is now being realized that we might have unique microbiome signature!!!!

The microbiota in our body is known to influence our good health. Recent evidence has linked the microbiome with different diseases. In fact, at least one parasitic protozoa - Toxoplasmosis gondii - has been shown to affect behaviour in rats. The protozoa reproduces only in cats, and studies have shown that when mice or rats are infected with it, the protozoan makes them less afraid of cats, and they are, therefore, more likely to be eaten by them.

Understanding microbiome and their interaction not only with their host but also between themselves are giving lot of food for thought in channelling our views of manipulating this micro-ecosystem in our body for desirable results. A case in point here is the role  and benefit of probiotics and as Prof David Relman (one of the pioneers in the field of microbiome research) puts it “The hesitation right now is there aren't a lot of good data. Most clinicians will say, 'I don't personally think it's doing much, but it can't hurt so if you feel better, why not.' I think there may be some real benefits, but I also think we have imprecise probiotic options now. So we're giving these somewhat irrelevant microorganisms to people, and yet they do seem to have some beneficial effects”(source -http://www.sfgate.com/health/article/Sequencing-of-human-microbiome-fills-knowledge-gap-3683156.php)

Therefore now is the right time to make maximum use of the data we derive from studying our microbiota and look at these organisms in a different perspective rather than thinking about them as our “enemies”. Also, I sincerely hope that pharma/biotech and nutraceutical companies collaborate to find better solutions to the diseases that we face today!
