PDS Biotechnology Corp (PDSB)
Phase 2 Interim Analysis in HPV Shows Strong Response Rate

PDS Biotechnology Corp operates as a clinical stage biotechnology company, principally involved in drug discovery in the United States. It is primarily engaged in the treatment of various early-stage and late-stage cancers, including head and neck cancer, prostate cancer, breast cancer, cervical cancer, anal cancer, and other cancers. Its products are based on the proprietary Versamune platform technology, which activates and directs the human immune system to unleash a powerful and targeted attack against cancer cells.

Refer to the full report for the price target, fundamental analysis, and rating.

PDS Biotech presented the first analysis from the Phase 2 trial testing PDS0101 in HPV16+ (human papilloma virus 16 positive) cancers.  The data presentation was from the first 25 patients out of the target enrollment of 56 patients. The trial enrolls patients who have failed first-line treatments but were naïve to checkpoint inhibitors as well as those who had become refractory to checkpoint inhibitor treatment.


PDS0101 is a triple combination therapy containing Versimue, the bifunctional checkpoint inhibitor bintrafusp, and Il-12 as an immune cytokine.  This combination is intended to allow the immune system to recognize the tumor cell, then activate both CD4+ helper and CD8+ killer T-cells for a potent and durable immune response. Survival for patients who tested HPV16+ was 89% compared with 57% for …

PDS Biotech Announces Release of Interim Data for PDS0101 in NCI-Led Phase 2 Clinical Study in Oral Presentation at ASCO 2021 Annual Meeting

 

Tumor reduction was observed in 83% (5 of 6) of HPV16-positive relapsed or refractory checkpoint inhibitor naïve advanced cancer patients and 58% (7 of 12) of HPV16-positive relapsed or refractory advanced cancer patients who have also failed checkpoint inhibitor therapy

FLORHAM PARK, N.J., June 08, 2021 (GLOBE NEWSWIRE) — PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing novel cancer therapies based on the Company’s proprietary Versamune^® T-cell activating technology, today announced the presentation of interim data from the Phase 2 trial led by the National Cancer Institute (NCI), of the National Institutes of Health (NIH), at the American Society of Clinical Oncology (ASCO) 2021 Annual Meeting.

The Phase 2 trial (NCT04287868) studies PDS0101 (Versamune^®-HPV16) in combination with two investigational immune-modulating agents: bintrafusp alfa (M7824), a bifunctional “trap” fusion protein targeting TGF-? and PD-L1, and NHS-IL12 (M9241), a tumor-targeting immunocytokine. PDS0101 is an immunotherapy candidate designed to treat cancers caused by infection with HPV16 (HPV16-positive cancers) by activating the immune system to produce in vivo CD8+ (killer) T-cells to target and kill tumors that are HPV16-positive. Analyses of immune responses and other immune correlates are ongoing.

Highlights from the presentation include the following:

• Data from a total of 25 patients with data available as of the time of presentation submission:
  • Update on the data previously reported for the original fourteen (14) HPV16-positive patients who were in the subject of the abstract published on May 19^th.
  • An additional seven (7) HPV16-negative patients (patients whose cancer was NOT caused by HPV16 infection) who were not discussed in the abstract.
  • An additional four (4) HPV16-positive patients who are checkpoint inhibitor refractory whose data became available after the abstract submission.
• 100% (25/25) of patients enrolled had failed chemotherapy treatment.
• 96% (24/25) of patients enrolled had failed both chemotherapy and radiation treatment.
• 56% (14/25) of patients enrolled had failed checkpoint inhibitor therapy (checkpoint inhibitor refractory).
• Most types of HPV-related cancers (anal, cervical, head and neck, vaginal and vulvar cancers) were represented among the study subjects.

• The following update was provided on the initial six (6) HPV16-positive patients who had NOT been treated with checkpoint inhibitors (checkpoint inhibitor naïve):
  • 83% (5/6) of the patients demonstrated an objective response (tumor reduction >30%).   The reported objective response rate with current standard of care checkpoint inhibitor treatment is 12-24%.
  • 100% (6/6) are still alive at 8 months – the historic average (median) survival or life span for this patient population is 7-11 months.
  • 80% (4/5) of patients who had an objective response still have an ongoing response at 8 months.
  • One (1) patient had a complete response (no evidence of disease).
  • No new patients had been added to this group by the time of submission.

• The following information was provided on the twelve (12) HPV16-positive patients who have also failed treatment with checkpoint inhibitors after failing chemotherapy and radiation treatment (checkpoint inhibitor refractory):
  • Four patients had recently been added since the abstract. Tumor reduction was observed in 58% (7/12), with an overall objective response rate of 42% (5/12) already achieved; the objective response rate of the current standard of care is 5-12%
  • One patient in this group had achieved a complete response by the time of reporting
  • 80% (4/5) of patients who had an objective response have an ongoing response at 8 months
  • 83% (10/12) of patients are still alive at 8 months; historic average (median) survival or life span for this patient population is only 3-4 months
    

• PDS0101 is designed to treat patients whose cancer is caused by infection with HPV16. Seven (7) patients had cancer that was not caused by HPV16 (HPV16-negative patients). In this group
  • 0% (0/7) experienced tumor reduction.
  • 80% (4/5) checkpoint inhibitor naïve patients are still alive at 8 months.
  • 0% (0/2) checkpoint inhibitor refractory patients are still alive at 8 months.

The NCI Center for Cancer Research’s Laboratory of Tumor Immunology and Biology (LTIB) and Genitourinary Malignancies Branch (GMB) are jointly leading this Phase 2 trial. Bintrafusp alfa is being jointly developed by Merck KGaA, Darmstadt, Germany, and GlaxoSmithKline; NHS-IL12 is being developed by Merck KGaA, Darmstadt, Germany.

The trial is evaluating the treatment combination in both checkpoint inhibitor naïve and refractory patients with advanced HPV-associated cancers that have progressed or returned after treatment. The vast majority of these cancers are caused by HPV16 infection. Objective response is measured by radiographic tumor responses according to RECIST 1.1. These reported data provide additional insights following the preclinical studies published by the NCI examining the potentially complementary mechanisms of action of the three immunotherapies, understood to involve potent in-vivo HPV16-specific killer and helper T-cell induction with effective T-cell tumor infiltration (PDS0101), blocking of immune checkpoints as well as targeting of TGF-? (Bintrafusp alfa). The preclinical results suggested superior tumor regression.

“The achievement of a 67% tumor reduction among all HPV16-positive cancer patients including both CPI naïve and CPI refractory patients continues to strengthen the evidence supporting continuing clinical investigation of novel Versamune^® platform’s potential ability to induce high levels of tumor-specific CD8+ killer T-cells that attack the cancer in which we believe results in a strong synergy with bintrafusp alfa and NHS-IL12. The data provide early evidence of notable clinical activity, and we saw effective tumor regression in these patients,” commented Dr. Lauren Wood, Chief Medical Officer of PDS Biotech. “The interim data demonstrating that this response was limited only to patients with HVP16-positive cancer, and also the fact that all responding patients who have stayed on treatment continue to show ongoing responses after a median duration of 8 months solidifies our belief that PDS0101’s ability to generate a robust, targeted T-cell response may have the potential to significantly improve clinical outcomes for patients with advanced, refractory HPV16-associated cancers who have limited treatment options.”

There are more than 630,000 cases of HPV-associated malignancies including cervical, oropharyngeal and anal cancer worldwide annually. HPV-16 is responsible for most of these cases. About 15-20% of HPV-associated malignancies respond to PD-(L)1 inhibitors. However, for the overwhelming majority of patients who progress on these immunotherapies there is no effective standard of care therapy.

The company is hosting a conference call today at 8:00 am ET to discuss the data presented at ASCO. Registration for the conference call is now open and a live webcast of the event will be available online in the investor relations section of the company’s website at https://pdsbiotech.com/investors/news-center/events. A replay will be available on the company website for 90 days following the webcast.

PDS Biotech Announces Release of Interim Data for PDS0101 in NCI-Led Phase 2 Clinical Study in Oral Presentation at ASCO 2021 Annual Meeting

 

Tumor reduction was observed in 83% (5 of 6) of HPV16-positive relapsed or refractory checkpoint inhibitor naïve advanced cancer patients and 58% (7 of 12) of HPV16-positive relapsed or refractory advanced cancer patients who have also failed checkpoint inhibitor therapy

FLORHAM PARK, N.J., June 08, 2021 (GLOBE NEWSWIRE) — PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing novel cancer therapies based on the Company’s proprietary Versamune^® T-cell activating technology, today announced the presentation of interim data from the Phase 2 trial led by the National Cancer Institute (NCI), of the National Institutes of Health (NIH), at the American Society of Clinical Oncology (ASCO) 2021 Annual Meeting.

The Phase 2 trial (NCT04287868) studies PDS0101 (Versamune^®-HPV16) in combination with two investigational immune-modulating agents: bintrafusp alfa (M7824), a bifunctional “trap” fusion protein targeting TGF-? and PD-L1, and NHS-IL12 (M9241), a tumor-targeting immunocytokine. PDS0101 is an immunotherapy candidate designed to treat cancers caused by infection with HPV16 (HPV16-positive cancers) by activating the immune system to produce in vivo CD8+ (killer) T-cells to target and kill tumors that are HPV16-positive. Analyses of immune responses and other immune correlates are ongoing.

Highlights from the presentation include the following:

• Data from a total of 25 patients with data available as of the time of presentation submission:
  • Update on the data previously reported for the original fourteen (14) HPV16-positive patients who were in the subject of the abstract published on May 19^th.
  • An additional seven (7) HPV16-negative patients (patients whose cancer was NOT caused by HPV16 infection) who were not discussed in the abstract.
  • An additional four (4) HPV16-positive patients who are checkpoint inhibitor refractory whose data became available after the abstract submission.
• 100% (25/25) of patients enrolled had failed chemotherapy treatment.
• 96% (24/25) of patients enrolled had failed both chemotherapy and radiation treatment.
• 56% (14/25) of patients enrolled had failed checkpoint inhibitor therapy (checkpoint inhibitor refractory).
• Most types of HPV-related cancers (anal, cervical, head and neck, vaginal and vulvar cancers) were represented among the study subjects.

• The following update was provided on the initial six (6) HPV16-positive patients who had NOT been treated with checkpoint inhibitors (checkpoint inhibitor naïve):
  • 83% (5/6) of the patients demonstrated an objective response (tumor reduction >30%).   The reported objective response rate with current standard of care checkpoint inhibitor treatment is 12-24%.
  • 100% (6/6) are still alive at 8 months – the historic average (median) survival or life span for this patient population is 7-11 months.
  • 80% (4/5) of patients who had an objective response still have an ongoing response at 8 months.
  • One (1) patient had a complete response (no evidence of disease).
  • No new patients had been added to this group by the time of submission.

• The following information was provided on the twelve (12) HPV16-positive patients who have also failed treatment with checkpoint inhibitors after failing chemotherapy and radiation treatment (checkpoint inhibitor refractory):
  • Four patients had recently been added since the abstract. Tumor reduction was observed in 58% (7/12), with an overall objective response rate of 42% (5/12) already achieved; the objective response rate of the current standard of care is 5-12%
  • One patient in this group had achieved a complete response by the time of reporting
  • 80% (4/5) of patients who had an objective response have an ongoing response at 8 months
  • 83% (10/12) of patients are still alive at 8 months; historic average (median) survival or life span for this patient population is only 3-4 months
    

• PDS0101 is designed to treat patients whose cancer is caused by infection with HPV16. Seven (7) patients had cancer that was not caused by HPV16 (HPV16-negative patients). In this group
  • 0% (0/7) experienced tumor reduction.
  • 80% (4/5) checkpoint inhibitor naïve patients are still alive at 8 months.
  • 0% (0/2) checkpoint inhibitor refractory patients are still alive at 8 months.

The NCI Center for Cancer Research’s Laboratory of Tumor Immunology and Biology (LTIB) and Genitourinary Malignancies Branch (GMB) are jointly leading this Phase 2 trial. Bintrafusp alfa is being jointly developed by Merck KGaA, Darmstadt, Germany, and GlaxoSmithKline; NHS-IL12 is being developed by Merck KGaA, Darmstadt, Germany.

The trial is evaluating the treatment combination in both checkpoint inhibitor naïve and refractory patients with advanced HPV-associated cancers that have progressed or returned after treatment. The vast majority of these cancers are caused by HPV16 infection. Objective response is measured by radiographic tumor responses according to RECIST 1.1. These reported data provide additional insights following the preclinical studies published by the NCI examining the potentially complementary mechanisms of action of the three immunotherapies, understood to involve potent in-vivo HPV16-specific killer and helper T-cell induction with effective T-cell tumor infiltration (PDS0101), blocking of immune checkpoints as well as targeting of TGF-? (Bintrafusp alfa). The preclinical results suggested superior tumor regression.

“The achievement of a 67% tumor reduction among all HPV16-positive cancer patients including both CPI naïve and CPI refractory patients continues to strengthen the evidence supporting continuing clinical investigation of novel Versamune^® platform’s potential ability to induce high levels of tumor-specific CD8+ killer T-cells that attack the cancer in which we believe results in a strong synergy with bintrafusp alfa and NHS-IL12. The data provide early evidence of notable clinical activity, and we saw effective tumor regression in these patients,” commented Dr. Lauren Wood, Chief Medical Officer of PDS Biotech. “The interim data demonstrating that this response was limited only to patients with HVP16-positive cancer, and also the fact that all responding patients who have stayed on treatment continue to show ongoing responses after a median duration of 8 months solidifies our belief that PDS0101’s ability to generate a robust, targeted T-cell response may have the potential to significantly improve clinical outcomes for patients with advanced, refractory HPV16-associated cancers who have limited treatment options.”

There are more than 630,000 cases of HPV-associated malignancies including cervical, oropharyngeal and anal cancer worldwide annually. HPV-16 is responsible for most of these cases. About 15-20% of HPV-associated malignancies respond to PD-(L)1 inhibitors. However, for the overwhelming majority of patients who progress on these immunotherapies there is no effective standard of care therapy.

The company is hosting a conference call today at 8:00 am ET to discuss the data presented at ASCO.

The Anti-Aging and Rejuvenating Properties of Stem Cells

 

In recent years, biomedical research on topics surrounding longevity and aging has gained a tremendous amount of traction. The biotech industry as well as major pharmaceutical companies, have also jumped onto the bandwagon of discovering ways to alter and reverse the aging process. Currently, the business of anti-aging is valued at about $110 billion and is expected to expand to more than $600 billion within the next four years¹. This new obsession with anti-aging is not without good reason; global aging is a concerning phenomenon. The United Nations estimates that by 2050, there will be more than 1.5 billion people aged 65 and over². As a result, the global incidence and burden of disease of age-related diseases will follow a similar trend. Therefore, the goal of anti-aging research is not solely to extend the human lifespan but to treat or prevent age-related diseases ranging from Alzheimer’s to Parkinson’s to diabetes and cardiovascular diseases, etc.

In order to achieve these goals, many of these biotech companies are leveraging on the regenerative prowess of stem cells
³.  This comes as no surprise since human pluripotent stem cells (hPSCs) are unlimited sources of self-renewing cells that can be differentiated into any cell type. This essentially means that large quantities of healthy and young hPSC-derived cells can easily be generated for cell replacement therapy. Also, stem cell-derived exosomes have recently come under the spotlight for their anti-aging properties. In addition, the induced pluripotent stem cells (iPSCs) technology can be leveraged to reverse aging phenotypes in cells. These will be further elaborated on in this article.

 

Aging and Stem Cells Share an Intimate Relationship

Aging is a complex biological process, but research has pointed to an intimate relationship between aging and stem cells⁴. Adult stem cells are found in many different organs and tissues, but they are low in numbers. They function to regenerate damaged cells and tissues. However, their regenerative capacity declines with age. This explains why injuries in older individuals take a longer time to heal as compared to a younger person. There are several mechanisms underlying the depreciation of adult stem cell functions⁵; targeting these mechanisms head-on may be a strategy to enhance the functions of adult stem cells as we age. However, there are other alternative solutions.

Firstly, therapeutics may be designed to enhance the function or proliferation of endogenous (existing) adult stem cells. Secondly, these adult stem cells can be isolated from tissues and expanded in vitro. Although difficult, researchers have been successful in isolating and expanding certain adult stem cells^6–8. These expanded cells can subsequently be used for transplantation to enhance cellular repair and tissue regeneration. In Herrera et al.’s (2006) study ⁶, they were able to isolate adult stem cells from adult human liver and after transplanting these cells into immune-deficient mice, the stem cells were able to regenerate portions of the liver. Thirdly, hPSCs can be differentiated into different types of progenitor cells using well-defined protocols. These hPSC-derived progenitors can then be used for transplantation⁹. Post-transplantation, these cells contribute to cell repair and regeneration, similar to that of adult stem cells. Recently, a group of researchers from the University of Tehran carefully differentiated hPSCs to cardiovascular progenitors before transplanting them into a rat model of myocardial infarction (heart attack). These progenitor cells significantly improved functionalities of the heart and reduced scar tissue formation in these rats¹⁰.

Although more work has to be done on improving the methods of isolating and expanding adult stems in vitro, and differentiating hPSCs to progenitor cells to ensure that the cells are safe and effective for use in transplantation therapies, there is great promise in utilizing these strategies to delay or prevent aging and age-associated diseases.

 

Exosomes Produced from Stem Cells

Another exciting frontier lies in the anti-aging properties of stem cell-derived exosomes. Studies have shown that exosomes derived from human embryonic stem cells, mesenchymal and stromal stem cells have regenerative capabilities^11–13. Exosomes are nano-sized, membrane-bound, extra-cellular particles secreted by cells. They contain various biological materials such as nucleic acids, proteins, metabolites, and function to facilitate cell-cell communication. While the underlying mechanisms as to how exosomes promote regeneration remains to be fully elucidated, it is likely that the amalgamation of inflammatory signals, growth factors, microRNAs, long non-coding RNAs, enzymes, and proteins found in exosomes promotes and reversal of cellular senescence, thus contributing to its anti-aging properties¹¹. Stem cell-derived exosomes are currently being explored as a therapeutic option for age-related musculoskeletal disorders¹⁴. Although research on exosomes is still in the early phases, exploitation of its anti-aging effects might potentially be a safe and effective anti-aging therapeutic strategy.

 

 

Stem Cell Technology Can Rejuvenate Old Cells

Yamanaka and colleagues’ Nobel prize-winning discovery of iPSCs revolutionized stem cell research^15,16. By simply introducing key transcription factors into adult cells, they can be reprogrammed back into a pluripotent state (‘infancy’). This process is known as cellular reprogramming, and the transcription factors are collectively referred to as ‘Yamanaka factors’. Recently, researchers from Stanford University were able to exploit this cellular reprogramming technology to rejuvenate old human cells¹⁷. By introducing several factors (including Yamanaka factors) transiently into old human cells, they were able to rewind these cells to a ‘youthful’ state, while preserving the cellular identities of cells. After further analysis, these rejuvenated cells were found to be more similar to younger cells than elderly cells.

As a proof of concept, the researchers then went on to introduce the same set of factors into aged mouse-derived skeletal muscle stem cells (MuSC) and transplanted them into the muscles of aged mice. Post-transplantation, these rejuvenated MuSCs were able to restore muscle functionality of old mice to a younger state. This remarkable study has illustrated that stem cell technology has great potential in reversing aging in cells to obtain ‘youthful’ cells and these cells could be used in cell transplantation therapies to treat age-related conditions. 

 

In the Coming Years

Experts agree that stem cell science holds answers to human longevity and has great potential in treating and preventing age-related diseases¹⁸. Numerous stakeholders in the biomedical industry have invested interests in tapping on stem cells to realize these goals. In the coming years, we will be expecting more research efforts dedicated towards a deeper level of understanding, as well as further optimization of stem cell-based interventions for aging. Companies involved in utilizing this science are worth researching and learning about while this segment of biotech is yet to approach potential.

How Virus Detectives Trace the Origins of an Outbreak – and Why it’s So Tricky

 

Every time there is a major disease outbreak, one of the first questions scientists and the public ask is: “Where did this come from?”

In order to predict and prevent future pandemics like COVID-19, researchers need to find the origin of the viruses that cause them. This is not a trivial task. The origin of HIV was not clear until 20 years after it spread around the world. Scientists still don’t know the origin of Ebola, even though it has caused periodic epidemics since the 1970s.

As an expert in viral ecology, I am often asked how scientists trace the origins of a virus. In my work, I have found many new viruses and some well-known pathogens that infect wild plants without causing any disease. Plant, animal or human, the methods are largely the same. Tracking down the origins of a virus involves a combination of extensive fieldwork, thorough lab testing and quite a bit of luck.

 

Viruses Jump from Wild Animal Hosts to Humans

Many viruses and other disease agents that infect people originate in animals. These diseases are zoonotic, meaning they are caused by animal viruses that jumped to people and adapted to spread through the human population.

It might be tempting to start the viral origin search by testing sick animals at the site of the first known human infection, but wild hosts often don’t show any symptoms. Viruses and their hosts adapt to each other over time, so viruses often don’t cause obvious disease symptoms until they’ve jumped to a new host species. Researchers can’t just look for sick animals.

Another problem is that people, and their food animals aren’t stationary. The place where researchers find the first infected person is not necessarily close to the place where the virus first emerged.

In the case of COVID-19, bats were an obvious first place to look. They’re known hosts for many coronaviruses and are the probable source of other zoonotic diseases like SARS and MERS.

For SARS-CoV-2, the virus that causes COVID-19, the nearest relative scientists have found so far is BatCoV RaTG13. This virus is part of a collection of bat coronaviruses discovered in 2011 and 2012 by virologists from the Wuhan Virology Institute. The virologists were looking for SARS-related coronaviruses in bats after the SARS-CoV-1 pandemic in 2003. They collected fecal samples and throat swabs from bats at a site in Yunnan Province about 932 miles (1,500 kilometers) from the institute’s lab in Wuhan, where they brought samples back for further study.

To test whether the bat coronaviruses could spread into people, researchers infected monkey kidney cells and human tumor-derived cells with the Yunnan samples. They found that a number of the viruses from this collection could replicate in the human cells, meaning they could potentially be transmitted directly from bats to humans without an intermediate host. Bats and people don’t come into direct contact very often, however, so an intermediate host is still quite likely.

 

Finding the Nearest Relatives

The next step is to determine how closely related a suspected wildlife virus is to the one infecting humans. Scientists do this by figuring out the genetic sequence of the virus, which involves determining the order of the basic building blocks, or nucleotides, that make up the genome. The more nucleotides two genetic sequences share, the more closely related they are.

Genetic sequencing of bat coronavirus RaTG13 showed it to be over 96% identical to SARS-CoV-2. This level of similarity means that RaTG13 is a pretty close relative to SARS-CoV-2, confirming that SARS-CoV-2 probably originated in bats, but is still too distant to be a direct ancestor. There likely was another host that caught the virus from bats and passed it on to humans.

Because some of the earliest cases of COVID-19 were found in people associated with the wildlife market in Wuhan, there was speculation that a wild animal from this market was the intermediate host between bats and humans. However, researchers never found the coronavirus in animals from the market.

Likewise, when a related coronavirus was identified in pangolins confiscated in an anti-smuggling operation in southern China, many leaped to the conclusion that SARS-CoV-2 had jumped from bats to pangolins to humans. The pangolin virus was found to be only 91% identical to SARS-CoV-2, though, making it unlikely to be a direct ancestor of the human virus.

To pinpoint the origin of SARS-CoV-2, a lot more wild samples need to be collected. This is a difficult task – sampling bats is time-consuming and requires strict precautions against accidental infection. Since SARS-related coronaviruses are found in bats across Asia, including Thailand and Japan, it’s a very big haystack to search for a very small needle.

 

 

Creating a family tree for SARS-CoV-2

In order to sort out the puzzle of viral origins and movement, scientists not only have to find the missing pieces, but also figure out how they all fit together. This requires collecting viral samples from human infections and comparing those genetic sequences both to each other and to other animal-derived viruses.

To determine how these viral samples are related to each other, researchers use computer tools to construct the virus’s family tree, or phylogeny. Researchers compare the genetic sequences of each viral sample and construct relationships by aligning and ranking genetic similarities and differences.

The direct ancestor to the virus, sharing the greatest genetic similarity, could be thought of as its parent. Variants sharing that same parent sequence but with enough changes to make them distinct from each other are like siblings. In the case of SARS-CoV-2, the South African variant, B.1.351, and the U.K. variant, B.1.1.7, are siblings.

Building a family tree is complicated by the fact that different analysis parameters can give different results: The same set of genetic sequences can produce two very different family trees.

For SARS-CoV-2, phylogenetic analysis proves particularly difficult. Though tens of thousands of SARS-CoV-2 sequences are now available, they don’t differ from one another enough to form a clear picture of how they’re related to each other.

 

The Current Debate: Wild Host or Lab Spillover?

Could SARS-CoV-2 have been released from a research lab? Although current evidence implies that this is not the case, 18 prominent virologists recently suggested that this question should be further investigated.

Although there has been speculation about SARS-CoV-2 being engineered in a lab, this possibility seems highly unlikely. When comparing the genetic sequence of wild RaTG13 with SARS-CoV-2, differences are randomly spread across the genome. In an engineered virus, there would be clear blocks of changes that represent introduced sequences from a different viral source.

There is one unique sequence in the SARS-CoV-2 genome that codes for a part of the spike protein that seems to play an important role in infecting people. Interestingly, a similar sequence is found in the MERS coronavirus that causes a disease similar to COVID-19.

Though it is not clear how SARS-CoV-2 acquired these sequences, viral evolution suggests they arose from natural processes. Viruses accumulate changes either by genetic exchange with other viruses and their hosts, or by random mistakes during replication. Viruses that gain a genetic change that gives them a reproductive advantage would typically continue to pass it on through replication. That MERS and SARS-CoV-2 share a similar sequence in this part of the genome suggests that it naturally evolved in both and spread because it helps them infect human cells.

 

Where to Go from Here?

Figuring out the origin of SARS-CoV-2 could give us clues to understand and predict future pandemics, but we may never know exactly where it came from. Regardless of how the SARS-CoV-2 jumped into humans, it’s here now, and it’s probably here to stay. Going forward, researchers need to continue monitoring its spread, and get as many people vaccinated as possible.

Refer to the full report for the price target, fundamental analysis, and rating.

2Q21 Results. For the fiscal second quarter ended April 30th, Avivagen reported revenue of $159,614 and a net loss of $2.2 million, or a loss of $0.04 per share. This compares to revenue of $29,625 and a net loss of $1.4 million, or $0.03 per share, in the same period last year. We had forecast revenue of $550,000 and a net loss of $1.3 million, or a loss of $0.02 per share.


Timing is Everything.  As with most early stage revenue companies, the timing of orders can have an outsized impact on quarterly results, and we believe this is what happened in the quarter when comparing actual results to our projections. In the broader picture, the miss is not material, as long as we continue to see building momentum going forward. The bottom line miss is related to $665,203 …
