The biotech IPO boom is becoming ‘historic’ as four more throw their hats in – Endpoints News

Four more US biotechs filed to go public Friday as yet more companies clamber to get through a yawning IPO window and onto a market thats signaled its willingness to reward nearly any new drugmaker.

The new entrants are led by ALX Oncology and the biological analytics biotech Berkeley Lights, each of whom filed to raise $100 million. The autoimmune company Pandion Therapeutics also filed for $75 million, and Kiromic Biopharma, a tiny immuno-oncology startup based in San Antonio, filed for $25 million.

These companies will try to capitalize on a 2020 biotech IPO boom that the investment firm Renaissance Capital recently called historic. The spree began in January and, after a brief interlude when the pandemic first hit the US and Europe, has only picked up in the last two months. The 23 companies that have gone public averaged an 80% return on their offering price, according to Renaissance Capital numbers. Every single one priced above their midpoint or upsized their offering.

Unlike most of their fellow newly or would-be public biotechs, Berkeley Lights will enter the market with significant revenue on the books. The company doesnt make drugs but instead has built a digital cell biology platform that can analyze living cells from a variety of different dimensions and, in principal, accelerate drug development. Theyve partnered with Sanofi and Pfizer on antibody discovery and last year, signed a $150 million pact with Ginkgo Bioworks to help the synthetic biology unicorn advance its genetic engineering capabilities.

All told, the company earned $51 million in revenue last year. Unlike a drug developer, they have no cash earmarked for specific pipeline products, and said they will use proceeds for research, potential acquisitions and general corporate purposes.

For ALX Oncology, a successful offering would mean their second $100 million tranche of the year. In February, the California biotech raised $105 million to help advance its sole pipeline candidate: an antibody designed to target CD-47. Thats the same dont-eat-me signal targeted by Irv Weissmans Forty Seven Inc., the biotech Gilead paid $5 billion for in January. ALXs pitch is that their antibodys FC receptor is engineered to not attract macrophages, reducing toxicity. The biotech will use their proceeds to push the drug through its ongoinghead and neck squamous cell carcinomaand gastric cancer trial and begin new trials for it in acute myeloid leukemia and myelodysplastic syndrome. A portion is also earmarked for CMC work.

Founded out of Polaris in 2018, Pandion Therapeutics was tapped last year for an up-to $800 million partnership to help a reorganizing Astellas develop antibodies for auto-immune disorders. That deal included $45 million upfront and the company also earned $80 million from a Series B in April. The new funding will be used to push their lead molecule through Phase I/II trials in ulcerative colitis while also backing preclinical research, particularly on a pair of antibodies meant to turn on the PD-1 checkpoint and tamp down the immune system.

Kiromic, meanwhile, is in part just trying to stay alive. With less than $2 million 5 million when a subsequent $3 million Series B is included in the bank at years end, they acknowledged in their S-1 that theres substantial doubt regarding the Companys ability to continue as a going concern. In this climate, though, thats worked out just fine for other companies. Applied Molecular Transport went publicin May with the same concerns. They ultimately raised $177 million.

If Biology Can Build It, They Will Come: Ginkgo Bioworks Is Laying The Foundation For The $4 Trillion Bioeconomy – Forbes

Early innovators in synthetic biology have had to get creative to grow not just their own ... [+] businesses, but the industry as a whole. Perhaps no company has contributed more to this growth than Ginkgo Bioworks.

Imagine there was a single method for making just about any product in the worldplastics, food, medicine, data storage devices, even a brain-computer interfaces. Now imagine that this method was faster, cheaper, and more sustainable than conventional manufacturing. Sounds like science fiction, right?

Its not science fiction: its synthetic biology, a field that uses biology as a manufacturing platform. Using the latest gene-editing techniques, synthetic biology can program yeast and bacteria into tiny cellular factories capable of making an endless range of products. Its also the driving force behind the $4 trillion bioeconomy, with great promise for building a more sustainable and abundant world.

Compared to sectors like pharmaceuticals and industrial chemicals, synthetic biology is relatively young. About 150 companies on Crunchbase describe themselves using the term synthetic biology, although SynBioBeta tracks more than 700 companies in the field. These early adopters either manufacture their own products with synthetic biology or provide synbio tools and technologies to help other companies transform the way they make things.

Early innovators in synthetic biology have had to get creative to grow not just their own businesses, but the industry as a wholeand perhaps few companies have contributed more to the industrys growth than Ginkgo Bioworks.

Ginkgo Bioworks is in a class of companies like Genomatica, Arzeda, Conagen, Zymergen, and Amyris AMRS that provides biotech infrastructure and servicesthe back-end of the synthetic biology industry. Rather than produce final products itself, Ginkgo designs and engineers microbes for a wide range of customer needs, from cannabinoid-producing bacteria to yeast that ferment next-generation food proteins.

Inside of Ginkgo Bioworks.

While Ginkgo believes that its microbes could one day produce virtually any physical good, most of Ginkgos would-be customers have relied for decades on traditional petrochemical or agricultural means of production. But Ginkgo isnt waiting for the slow, gradual adoption of synthetic biology by old-world players. Instead, its bringing its biology-based approach to the market by creating its own demand.

Already, Ginkgo has announced three spin-outs and strategic investments:

In February 2019 Ginkgo launched Motif Foodworks with a $90 million Series A, the largest in food tech history. This spin-out is using microbes to provide next-generation alternative proteins and other ingredients to food companies, showing the holistic view Ginkgo takes in the synthetic biology market. Ginkgo spun out Motif to develop and manufacture animal-free food ingredients, betting that plant-based meats and alternative dairy products would grow into a lucrative market. As part of this spin-out, a servicing agreement positioned Ginkgo as the provider of the microbes that Motif would use to manufacture its products.

Depending on the project, a subsidiary like Motif might have access to Ginkgos platform and technology at no cost. Alternatively, the investment may have dollars specifically earmarked for Ginkgos services, resulting in an immediate, new revenue-paying customer. Regardless of the initial financial arrangement, Ginkgo successfully created both a promising investment and a reliable future customer in one ambitious move.

Joyn Bio is a joint venture announced in March 2018 and funded to the tune of $100 million by agricultural giant Bayer, Ginkgo, and Viking Global Investors. The Joyn Bio venture carries technological benefits as well, with 100,000 of Bayers proprietary microbial strains being shared with Gingko. These strains can now be incorporated into Ginkgos internal metagenomics database. Even without explicit IP transfer, Ginkgo gets to flex its technological and commercial muscles in the context of a new industry.

In the pharmaceutical industry, Ginkgo has invested $80 million in its partner Synlogic, which will use Ginkgos cell programming platform to accelerate Synlogics pipeline of living medicines. Both companies believe that the ability to program living cells to sense and respond to treat complex diseases has great potential, possibly transforming the next generation of pharmaceuticals.

Aoife Brennan, Synlogic CEO

We have been working with Ginkgo for over two years now, said Aoife Brennan, Synlogic CEO. We initially started with a pilot project that went so well, we expanded our collaboration.

Brennan says Synlogic has really benefited as a company from working with Ginkgo. Having access to Ginkgos expertise and foundry services has allowed us to initiate more projects and to make sure that we are moving the best synthetic biotics into further development.

Brennan says that Ginkgo is not just a good collaborator, it also shares her companys values. Both of our companies share a passion for synthetic biology and making a positive impact on the world.

As Ginkgo seeks to attract customers in new markets, spin-outs and investments like Motif, Joyn Bio, and Synlogic demonstrate to other big players how synthetic biology is going to disrupt industries like food, agriculture, and pharmaand how synthetic biology can be used to transform their own businesses.

With this business model successfully piloted, Ginkgo has begun building a pipeline of promising biotech start-ups poised to be users of its microbial design platform. Partnering with start-up incubators Y Combinator and Petri, Ginkgo offers select start-ups access to its services in exchange for equity. The start-ups benefit from access to a technology stack that can save them large amounts of capital and time that would otherwise be sunk into building their own microbial design infrastructure.

Y Combinator partner Jared Friedman

"Ginkgo Bioworks was the first life sciences company YC funded, back in 2014, Y Combinator partner Jared Friedman told me. We believed early on that what they were building would help power the next generation of synbio startups, and it's been impressive to see them execute on that mission.

Friedman says that Ginkgo is making it cheaper and easier for new companies to get started by providing them with a platform that makes engineering biology easier.

We have a shared vision for the future, one in which bio startups are as easy to start as software startups, where founders don't have to spend years and millions of dollars booting up a genetic engineering lab, said Friedman. We're proud to be part of Ginkgo's continuing work to make this the standard."

Further enhancing this early pipeline of start-ups which rely on Ginkgos platform, the company recently announced the creation of a $350 million Ferment Fund. The Ferment Fund will spin out additional companies into promising markets identified by the Ginkgo team. Not only do these investments provide Ginkgo with a stake in promising biotech firms, but they also enable Ginkgo to support the growth of a synbio ecosystem reliant on its platform.

In a demonstration of the flexibility of the companys technology platform, as well as its commitment to help in the fight against the coronavirus, Ginkgo recently took several actions to help scale the research communitys response to the pandemic.

Ginkgo announced Concentric, a program to offer COVID-19 testing at scale to support schools and businesses in their reopening strategies. Concentric can provide end-to-end, on-site testing services for organizations that seek to make testing available to their communities.

Testing is essential for understanding and stopping the spread of the virus, Ginkgo said in an op/ed. By repurposing its next-generation sequencing capacity to rapidly scale testing, Ginkgo hopes to turn the tide.

In March, Ginkgo pledged $25 million of its research and development resources to help researchers battling the coronavirus. Ginkgo has used its DNA synthesis capabilities to make the viruss sequences freely available for use in R&D for diagnostics, therapeutics and vaccines. Ginkgo also is a part of a Berkeley Lights consortium for antibody discovery and testing, helping to scale up infrastructure for antibody lead optimization.

As synthetic biology start-ups grow, they will continue to lean on Ginkgos platform for microbial design, since developing in-house capabilities will appear increasingly redundant with each successful Ginkgo collaboration. In this way, Ginkgo will have created a robust ecosystem of companies modeled after its own Motif Foodworks, full of start-ups that excel at developing and biomanufacturing final products while they outsource their microbial design to the Ginkgo Bioworks mothership.

Berkeley Lights Announces Opto(TM) Antigen-Presenting Bead Kit to Accelerate the Expansion of Antigen-Specific T Cells Used to Develop Cell-Based…

EMERYVILLE, Calif., June 24, 2020 /PRNewswire/ --Berkeley Lights, Inc., a leader in Digital Cell Biology, today announced the Opto Antigen-Presenting Bead (APB) kit, a new reagent kit that activates and expands antigen-specific T cells in peripheral blood to create artificial T cells. The APB kit is ten times more effective than the current, standard dendritic cell process, which is used for antigen discovery for cancer vaccines, TCR discovery for transgenic TCR cell therapy, and expansion of antigen-specific T cells for endogenous T cell therapy.

The APB kit is a part of the company's Opto Cell Therapy Development 2.0 workflow and with this new kit, scientists can measure multiple cytokines, visualize tumor cell killing,andexpand & validate rare T cells on the Beacon and Lightning systems. The functional properties of the resulting T cells are assayed and recovered for TCR or genome sequencing.

"T cell-based therapies are showing great promise for cancer treatment," said John Proctor, Ph.D., Senior Vice President of Marketing at Berkeley Lights. "Our APB kit will provide scientists developing these therapies with a way to rapidly identify existing T cells that will react to tumor antigens and expand them to generate enough antigen-specific T cells for use in TCR discovery and production of T cell therapies. Ultimately, we believe the APB kit will enable scientists to move to the next step of developing T cell-based therapies more quickly and efficiently."

The APB kit allows scientists to load any peptide onto a bead and measure critical peptide-Human Leukocyte Antigen (HLA) interactions before stimulating antigen-specific T cells with the best peptides. This new workflow removes the need to assay ineffective peptides that do not bind to the HLA complex in the first place. The APB kit consists of beads coated with co-stimulatory antibodies, an HLA complex that measures the degree of loading and stability of the peptide, and tetramers that stain the antigen-specific T cells that are generated. By replacing the role of dendritic cells in T cell workflows, this kit enables Berkeley Lights' customers to save time and costs by removing variability in antigen presentation.

The Opto Antigen-Presenting Bead (APB) kit will be available in early Fall 2020. More information can be found here: http://www.berkeleylights.com. Berkeley Lights' Beacon and Lightning systems and Culture Station instrument are for research use only. Not for use in diagnostic procedures.

About Berkeley LightsBerkeley Lights is a leading Digital Cell Biology company focused on enabling and accelerating the rapid development and commercialization of biotherapeutics and other cell-based products for our customers. The Berkeley Lights Platform captures deep phenotypic, functional and genotypic information for thousands of single cells in parallel and can also deliver the live biology customers desire in the form of the best cells.

Biologists Unravel Tangled Mystery of Plant Cell Growth Insight Could Lead to Bigger Crops and Better Yields – SciTechDaily

When cells dont divide into proper copies of themselves, living things fail to grow as they should. For the first time, scientists now understand how a protein called TANGLED1 can lead to accurate cell division in plants.

Inside cells are structures called microtubules, which act like highways for moving proteins and organelles. Theyre also critical for separating DNA after it has been duplicated to eventually make two cells from one.

You cant live without microtubules, and plants cant either, said Carolyn Rasmussen, an assistant professor of plant cell biology at UC Riveride. Because theyre so important, where they go and how they move has to be carefully controlled.

Rasmussen and colleagues discovered that the TANGLED1 protein performs this microtubule controlling function by binding the microtubules together like glue. Their description of how TANGLED1 operates was published today (June 22, 2020) in the Journal of Cell Biology.

By adding together microtubules and TANGLED1 in a test tube, the team saw surprising interactions between them. Often, proteins can only bundle microtubules at very specific angles 40 degrees or less. TANGLED1 can grab microtubules from any angle and link them together.

To the best of my knowledge, this is the first plant protein observed in vitro with this characteristic, Rasmussen said.

The proteins ability to capture and stabilize microtubules is likely critical for being able to separate daughter cells properly. Cell divisions at the wrong angle lead to big problems such as the formation of tumors.

Animal cells normally need to remain attached to a surface, and their division is controlled to ensure the cells remain there. If a cell becomes unattached to the surface after division, that could mark the beginning of a tumor.

Rasmussens team included Pablo Martinez, Sean OLeary, and Antonia Zhang from UC Riverside; biochemists Ram Dixit and Rachappa Balkunde from Washington University; and mathematician Kenneth Brakke from Susquehanna University.

Now that the team has seen TANGLED1 at work in vitro, the next step is to observe it in a living cell. If they can gain a deeper understanding of the genes that control plant cell division, these genes might be manipulated to produce higher yield crops, such as bigger ears of corn or more grain.

An additional benefit of this research is the insight it could yield into human cellular processes. When there are defects in the cells ability to move material around on microtubules, diseases such as Alzheimers disease or cancer could follow.

Research on these diseases is often conducted on human cell lines or animal models. However, there are similarities between the microtubule bundling behavior of TANGLED1 in plants and microtubule binding proteins in humans, making it easier to learn more by characterizing both at the same time.

People say plants dont get cancer, which is generally true, Rasmussen said. But sometimes when you have a different perspective on a related question in this case, what controls the spatial positioning of cell division you can see things that are hard to see in other model systems.

Neurons thrive even when malnourished – Newswise

Newswise ITHACA, N.Y. When animal, insect or human embryos grow in a malnourished environment, their developing nervous systems get first pick of any available nutrients so that new neurons can be made.

In this process, called organ sparing, resources are preferentially delegated to the nervous system at the cost of less important organs or tissues.

New research now shows that developing nervous systems demonstrate this preferential growth even at the level of individual neurons. In a paper published in eLife June 22,Low FoxO expression in Drosophila somatosensory neurons protects dendrite growth under nutrient restriction,a team of Cornell researchers discovered the molecular mechanism that helps facilitate organ sparing on this cell-by-cell basis.

The phenomena we found is similar to the phenomena of the sparing of the brain, but there are very important differences, saidChun Han, senior author and a Nancy M. and Samuel C. Fleming Associate Professor in the Department of Molecular Biology and Genetics in the College of Agriculture and Life Sciences and in the Weill Institute for Cell and Molecular Biology. The neurons are protected at the growth level of individual neurons, and they become bigger and bigger by extending their branches.

Those branches are called dendrites. They form a system of elaborate arms that extend from neurons cellular bodies, and they can receive stimuli from the external environment.

Han and his team wanted to look at how nutrient deficiency affects the dendrite growth of individual neurons, and then examine what cellular sacrifices bodies make so that vital organs, including the brain, continue to develop.

They divided Drosophila (fruit fly) larva into groups receiving either a high- or low-yeast diet, simulating nutrient-rich and nutrient-poor environments. Then they observed how neural cells developed compared to neighboring skin cells on the body wall. They monitored the progress every 24 hours using confocal microscopy that uses lasers to light up fluorescent markers that label individual cells.

We have very beautiful markers that specifically label these populations of neurons, Han said. Every neuron is very clear to us down to every single branch.

The researchers observed that the neurons grew at a much higher rate than skin cells in the low-yeast environment. Skin cells grew faster when there was less competition for nutrients. Han and his team learned that this difference is due to a critical gene called FoxO an important regulator of cellular stress response.

FoxO is a gene thats expressed in pretty much most cells of the body, Han said. When the cells face low nutrients, FoxO puts a brake on the system and slows cell growth.

Whats particularly interesting about FoxO is that just because most cells have it, doesnt mean they all use it at the same time or under the same conditions. Hans team discovered that even during malnutrition, the Drosophila neurons expressed very little FoxO, whereas the epidermal cells expressed FoxO at much higher levels.

When there are fewer nutrients available, FoxO triggers a response in epidermal cells called autophagy, which tells the cell to self-destruct by consuming itself. However, the limited FoxO expression in neurons preserves individual neural cells and their dendrite growth.

And while humans have more complex systems than Drosophila, Han said that this research helps pave the way for investigating similar phenomenon in humans.

Our study reveals another layer of nervous system sparing under nutrient deficiency and discovers a novel mechanism by which neurons are protected. Han said. These findings may facilitate the development of better approaches to treat problems caused by malnutrition during early development.

Co-authors include Amy Poe, Ph.D. 18; graduate student Yineng Xu; Christine Zhang 19; Joyce Lei 21; Kailyn Li 17; and David Labib 20; they conducted research through theHan Labin the Weill Institute for Cell and Molecular Biology and the Department of Microbiology and Genetics. Poe is currently a postdoctoral researcher at the University of Pennsylvania Perelman School of Medicine; Li is currently in the Doctor of Medicine Program at Weill Cornell Medicine.

This research was supported by a Cornell startup fund and two grants from the National Institutes of Health.

Prevention of sugar uptake can make cancer cells more sensitive to chemotherapy – News-Medical.Net

By preventing sugar uptake, researchers succeeded in increasing the cancer cells' sensitivity to chemotherapeutic treatment.

The studies, led by researchers at Lund University in Sweden, were carried out on cancer cells in a lab environment. The results were recently published in the research journal Haematologica.

Just like the body's cells, cancer cells need energy like the sugar molecule, glucose. Researchers have long been interested in finding out if it is possible to "starve" cancer cells by preventing sugar uptake.

It is also known that some cancer cells increase their intake of sugar molecules as a survival strategy, which can reduce the effect of treatment. Would it be possible to prevent glucose from entering the cancer cell and in that way increase the effect of chemotherapy?

This is what researchers at Lund University and the University of Pisa have studied.

To enable sugar molecules to enter the cancer cell through the cell membrane, the cell uses so-called sugar transporters, which can be likened to swing doors that let substances in and out.

In total, the researchers can currently identify 14 such sugar transporters. In the present study, the researchers investigated number 1, GLUT1, and its role in acute myeloid leukaemia (AML).

By introducing specially designed inhibitors - substances that prevent or impede activities in the cell membrane - the researchers succeeded in blocking sugar uptake to the cancer cells.

We then examined whether the effect of the chemo used in the treatment of AML was improved when we blocked the sugar uptake. It was clear that the cancer cells became far more sensitive to the chemo drugs"

Karin Lindkvist, Study Lead Author and Professor, Department of Cell Biology, Lund University

The form of cancer the researchers studied, acute myeloid leukaemia, is one of the most common forms of leukaemia among adults.

AML has a relatively poor prognosis and a high risk of relapse, above all among the elderly population, as they often cannot tolerate the tough treatment regime as good as younger patients can.

"Our hope is that combining chemotherapy with inhibitors that block the sugar uptake to the cancer cells, can improve the effect of the treatment and thereby cure more patients in the future", states Anna Hagstrm, Senior Lecturer at the Division of Clinical Genetics, Lund University, and co-author of the study.

Understanding these proteins and how they regulate its swing doors is an important field of research, says Karin Lindkvist.

"Membrane proteins are targets of interest in the development of new treatments and it is commonly known that around half of all drugs on the market today target membrane proteins."

"There is a lot happening in the cell, and these proteins control what goes in and out of the cell."

"This particular sugar transporter appears to play a key role, as it is highly effective at helping the cell to take up sugar. It is also why the cancer cells make more of this transporter in order to obtain more energy", says Karin Lindkvist.

A lot of research remains to be done before it can be used in patients.

"The results need to be repeated both in experimental studies and clinical trials. My hope is that someone will take this further with the aim to treat patients suffering from AML or other cancer diseases that we know use GLUT1 transporters for sugar uptake", she concludes.

INRS researchers involved in work to create a COVID-19 vaccine – Laval News

Professors Nicolas Doucet andYves St-Pierreof the Laval-based Institut national de la recherche scientifique (INRS) are contributing their expertise in structural and cell biology to the race for a vaccine against COVID-19.

In partnership with Glycovax Pharma, a company with operations also in Laval, the two researchers will evaluate the feasibility of a vaccine strategy targeting carbohydrate molecules located on the surface of the coronavirus Spike protein.

A fortunate coincidence

It was a fortunate coincidence that the carbohydrate molecules on which the biopharmaceutical company has been working on since 2017 are present on the Spike protein. Glycovax Pharma is one step ahead because antibody development is already ongoing, says Professor Doucet.

Even if antibodies are currently being synthesized, two key issues need to be considered. First, the antibodies must be able to reach the targeted carbohydrates on the Spike protein. Researchers also need to ensure that these carbohydrate molecules are present on the Spike protein at all times, regardless of the type of infected cells in the host.

Essential steps to follow

For instance, SARS-CoV-2 is known to attack the respiratory system, so if the lung cells do not attach the proper carbohydrates of interest to the coronavirus Spike protein after infection, the strategy may not be effective, he cautions.

These are essential steps in validating a vaccine approach. Our results will allow Glycovax Pharma to prioritize certain antibodies or to put forward other complementary approaches, he says.

The research project in partnership with Glycovax Pharma is funded by a Mitacs Accelerate grant that will support the work of postdoctoral fellow Yossef Lpez de los Santos over the next year.

An exciting project

Its exciting to be part of a talented team that is committed to fighting the COVID-19 pandemic, he says. I see our goal as quite ambitious, but at the same time, its a great opportunity to use our expertise in structural biology to help address a global problem.

This partnership with INRS experts in structural and cellular biology represents an important contribution in the pursuit of our work, saysDany Valiquette, president of Glycovax. Their contribution will help us take essential steps in the development of a new vaccine to counter COVID-19.
