Evotec Makes Move into Gene Therapy with Takeda… – Labiotech.eu

German biotech giant Evotec has moved into gene therapy and partnered with Takeda to develop new therapies in oncology, rare diseases, neuroscience, and gastroenterology.

The two companies did not reveal financial details of the collaboration, but did say that it will be a multi-year alliance that adds to Evotecs existing deal with the big pharma that stretches back more than 10 years. The four therapy areas they will concentrate on align with Takedas core therapeutic focus.

The alliance with Takeda gives us a head start, Evotec CEO Werner Lanthaler told me. Takeda has strong experience in gene therapy and we are proud that they have chosen us as a partner.

Evotec also announced it will be opening a 20-person R&D site in Austria, in Orth an der Donau, to work on its gene therapies. While this will be run independently from the Takeda deal, according to Lanthaler, he said the discussions around the collaboration happened at the same time as the gene therapy site was being set up.

The site known as Evotec GT will be led by Friedrich Scheiflinger, who worked for Takeda before moving to Evotec. According to a statement from Evotec, the team has worked together for many years and as well as a focus on gene therapy techniques, has expertise in virology and blood disorders, as well as metabolic and muscle diseases.

Gene therapy has undergone a revolution in recent years and has changed dramatically since the 90s. With approvals of therapies such as the eye gene therapy Luxturna in 2018, many companies are now investing in and working to develop similar therapies.

One reason Evotec cites for moving into this area is the potential for rapid market growth. At present, there are only a few gene therapies on the market, but there are many in development. The value of the market is expected to reach 4.6B by 2025, a dramatic increase from 459M in 2018.

Evotec is also working on various other advanced therapies, including cell therapy with its EVOcells platform. The company announced last week that it made a licensing and investment agreement with Canadian biotech panCELLa, a company modifying cell therapies to evade the immune system and prevent rejection. Evotec additionally has a PanOmics platform that combines transcriptomics and proteomics data to find new drug targets.

After expanding our biologics capabilities through the acquisition of Just Evotec Biologics in 2019, Evotec GT is yet another important piece to complete the multimodality puzzle, explained Lathaler.

The timing was ideal, as Evotec GT brings our existing expertise in the gene therapy field to a new level. It also has close technological ties especially to our induced pluripotent stem cells and PanOmics platforms, so these platforms can grow and gain traction together.

Evotec Expands Its IPSC-Based Cell Therapy Platform Evocells Through Licensing Agreement with panCella – Benzinga

HAMBURG, GERMANY, AND TORONTO, ON / ACCESSWIRE / April 2, 2020 / Evotec SE ((Frankfurt Stock Exchange: EVT, MDAX/TecDAX, OTC:EVOTF) and the innovative biotechnology company panCELLa Inc. announced today that the companies have entered into a licensing and investment agreement.

Under the terms of the agreement, Evotec will receive a non-exclusive licence to access panCELLa's proprietary iPS cell lines "iACT Stealth Cells(TM)", which are genetically modified to prevent immune rejection of derived cell therapy products ("cloaking"). Furthermore, Evotec will also have access to a new-generation cloaking technology known as hypoimmunogenic cells. In addition, the "FailSafe(TM)" mechanism effectively addresses a key challenge in iPSC-based cell therapy, potential tumour formation by residual undifferentiated cells.

Using the cell lines, Evotec will be able to develop iPSC-based, off-the-shelf cell therapies with long-lasting efficacy that can be safely administered to a broad population of patients without the use of medication to supress the patients' immune system. With a growing portfolio of iPSC-based cell therapy projects at Evotec, access to research as well as GMP-grade iPSC lines modified with one or both of the panCELLa technologies significantly accelerates Evotec's cell therapy discovery and development efforts. Modified iPSC lines will be available for the development of cell therapy approaches across a broad range of indications by Evotec and potential partners. Furthermore, Evotec has made an investment to take a minority stake in panCELLa and has nominated Dr Andreas Scheel to join panCELLa's supervisory board.

Dr Cord Dohrmann, Chief Scientific Officer of Evotec, commented: "Cell therapies hold enormous potential as truly regenerative or curative approaches for a broad range of different diseases with significant medical need. Integrating panCELLa's technology and cell lines into our ongoing proprietary research and development efforts strengthens Evotec's position in cell therapy. It is our goal to provide safe highly-effective cell therapy products to as many patients as possible. In addition to small molecules and biologics, cell therapy will become yet another major pillar of Evotec's multimodality discovery and development platform."

Mahendra Rao, MD, PhD, CEO at panCELLa, added: "We welcome the partnership with Evotec. Evotec's widely recognised expertise and existing portfolio of iPSC-related technology platforms will allow panCELLa to rapidly advance its own therapeutic interests in NK cell therapy, pancreatic islet production and iPSC-derived MSC platform, in addition to enabling panCELLa to make its platform technologies widely available. I believe that the investment by Evotec in our company is a strong validation of the leading role of panCELLa in the field of regenerative medicine and in the utility of its platform technologies. We welcome Dr Andreas Scheel to our Board."

No financial details of the agreement were disclosed.

About Evotec and iPSCInduced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from adult cells. The iPSC technology was pioneered by Shinya Yamanaka's lab in Kyoto, Japan, who showed in 2006 that the introduction of four specific genes encoding transcription factors could convert adult cells into pluripotent stem cells. He was awarded the 2012 Nobel Prize along with Sir John Gurdon "for the discovery that mature cells can be reprogrammed to become pluripotent". Pluripotent stem cells hold great promise in the field of regenerative medicine. Because they can propagate indefinitely, as well as give rise to every other cell type in the body (such as neurons, heart, pancreatic and liver cells), they represent a single source of cells that could be used to replace those lost to damage or disease.

Evotec has built an industrialised iPSC infrastructure that represents one of the largest and most sophisticated iPSC platforms in the industry. Evotec's iPSC platform has been developed over the last years with the goal to industrialise iPSC-based drug screening in terms of throughput, reproducibility and robustness to reach the highest industrial standards, and to use iPSC-based cells in cell therapy approaches via the Company's proprietary EVOcells platform.

About cell therapy and panCELLa's FailSafe(TM) iPSC technologyCell therapy, one of the most promising regenerative medicine approaches, replaces a patient's missing or broken cells with functioning cells from a range of different sources, either from a donor, from the patient's own material, or from stem cells. The advent of induced pluripotent stem cells ("iPSC") has opened up stem cells as an almost unlimited source of consistent-quality material for such cell therapies. At the same time, differentiating cell therapies from a single validated source circumvents critical risks of contamination associated with administering both donor and patient cell material.

However, the patient's immune system will treat such iPSC-based transplants as "foreign" and use the body's immune system to counteract the therapy, thus undermining its long-term efficacy. While organ transplants require an often lifelong regimen of immunosuppressants, iPSC-derived cells used for cell therapies can be cloaked to make them undetectable by the patient's immune system, thus avoiding rejection and enabling effective long-term relief of the patient's symptoms.

To increase the safety of such iPSC-derived cell products, panCELLa's proprietary FailSafe(TM) technology is able to inactivate any iPSC-derived proliferating cell before and after transplantation through the use of a readily available anti-infective medication. FailSafe(TM) is the only quantifiable "safety switch" on the market which is expected to be critical for regulators, clinicians and patients to make informed decisions when evaluating treatment options.

ABOUT PANCELLA INC.Incorporated in August 2015, panCELLa (www.pancella.com) was founded by Dr Andras Nagy and Dr Armand Keating based on Dr Nagy's ground-breaking work in the area of stem cell research. Through panCELLa, Drs Keating and Nagy are seeking to create an effective cell therapy derived from stem cells, which are modified to provide a sufficient and very high level of safety before and after the cells are introduced to the patient. panCELLa serves those companies developing products from stem cells. panCELLa seeks to create universal "off the shelf" FailSafe(TM) Cells and to assist pharmaceutical and biotechnology sectors to achieve such with their own cell lines. Targeted medical applications include deadly, debilitating, or aggressive diseases requiring immediate treatment where there is no time to cultivate a customized stem cell treatment from the patient (i.e. cancer, cardiac infarct, diabetes, stroke and spinal cord injury).

Anti-IL-6 Monoclonal Antibodies as Antiarrhythmic Treatment for HF – The Cardiology Advisor

, which were found to produce high levels of Interleukin-6 (IL-6), was abated in the presence of anti-IL-6 monoclonal antibodies, according to study results intended to be presented at the annual meeting of the American College of Cardiology (ACC.20).

In a diseased state, cardiacmesenchymal stromal cells (cMSCs) remodel and secrete inflammatory cytokines,including IL-6. IL-6 has been shown to be a potent inducer of Ca2+-mediatedarrhythmia substrates in human myocytes. While anti-IL-6 monoclonal antibodies havean established role in the treatment of autoimmune diseases and malignancies, theiruse in the treatment of cardiac disease has not been well studied.

Using extracted device leads and explanted hearts from patients with and without heart failure, investigators isolated cMSCs (failing and non-failing cMSCs, respectively), and quantified IL-6 using an enzyme-linked immunosorbent assay. Myocytes were derived from induced pluripotent stem cells (iPSCs) from individuals without heart failure and cultured in monolayers. Myocytes were treated with exogenous IL-6 or cocultured with failing cMSCs with and without anti-IL-6 monoclonal antibody. Fluorescent indicators were used to detect the presence of Ca2+ alternans during steady state pacing.

The secretion of IL-6 was found tobe 5.6 times higher in failing vs nonfailing cMSCs (n=4; P <.005) and 66 times higher in cMSCs vs iPSC-derived humanmyocytes (n=5; P <.002). Myocytes thatwere cocultured with failing cMSCs or were exposed to exogenous IL-6 had largeincreases in Ca2+ alternans compared with myocytes cultured alone (343%,n=12, P <.001 and 300%, n=5, P <.002, respectively). These Ca2+alternans were reduced to baseline levels in myocyte/cMSC cocultures treated vsnot treated with IL-6 (reduction, 400%; n=18, P <.001).

These results suggest anovel anti-arrhythmic therapeutic strategy in heart failure using anti-IL-6drugs such as tocilizumab, sarilumab, or siltuximab, concluded theresearchers.

A New NK Cell-based Immunotherapy For Cancer Treatment – Health News Today

The immunotherapy uses the bodys immune cells or immune cells of a matched donor for the treatment of cancer and for some patients it yields good results in clinical trials.

Researchers from Washington University School of Medicine in St. Louis found that the effectiveness of immunotherapy depends on the age of immune cells. The natural killer (NK) cells, in their early development, are more effective and could be developed from human pluripotent stem cells without utilizing the cells from a matched donor or patient.

Detailed findings of this study are published in the journal Developmental Cell.

Research leader Christopher M. Sturgeon found that the effectiveness of natural killer cells is highly consistent and would not need cells from the patient or the donor. Researchers are working to increase the effectiveness of immunotherapy for cancer patients and revealed that these natural killer cells could be manufactured from the existing cell under strict guidelines and could be easily available for the patients whenever they need them.

Adult versions of natural killer cells originate from bone marrow and are used in investigational therapies while earlier natural killer cells form in the yolk sac of the early embryos of mammals. These earlier versions of NK cells are short-lived immune cells and can originate from human pluripotent stem cells for therapeutic purposes because these stem cells tend to produce different types of cells including NK cells.

Producing such cells from stem cells removes the time to utilize patients or donors cells and make it easily available for cancer patients.

Sturgeon found that in the early stage of embryo development, there is no bone marrow but still there is the production of blood. To keep the embryo alive, there is a brief supply of blood by the yolk sac until bone marrow starts the production of blood. These early blood cells seem to be capable of producing natural killer cells that adult blood cells cant produce.

Researchers tempted induced pluripotent stem cells of human and mouse to form specific natural killer cells and showed that these early versions of natural killer cells are better than adults ones in releasing anti-tumor chemicals through a process called degranulation.

The research team adds that adult version of natural killer cells provokes harmful inflammation by releasing different chemicals but unfortunately these chemicals are not helpful against cancer.

In the past work by other research groups, the origin of natural killer cells was a question mark. These groups suggested that early versions of natural killer cells are more helpful against cancer but how and why they were effective was unknown.

But now the origin of these unique natural killer cells is known. Natural killer cells could be originated from existing pluripotent stem cells and unlike T cell therapies, NK cells dont harm healthy cells of body tissues. In case, if NK cells cause harm they do not stay longer in the body.

Sturgeon was interested to know the reason for their presence in the early embryo and assumed that during rapid cell division in the early embryo NK cells supervise the protection against infection or cancer. This study opens doors to manufacture early versions of NK cells from human pluripotent stem cells for clinical trials.

Coriell Institute for Medical Research Awarded $8.6 Million Biobanking Contract from National Institute on Aging – Newswise

Newswise The National Institute on Aging (NIA) has extended its biobanking contract with the Coriell Institute for Medical Research for an additional five years.

The newly awarded $8.6 million funding keeps Coriell in place as the trusted steward of this collection and includes the addition of new innovative products to expand the collection. The NIA Aging Cell Repository was established at Coriell in 1974 and Coriell has continuously managed this unique resource ever since.

Coriells relationship with the NIA is among its oldest and most treasured, said Nahid Turan, Coriell's Chief Biobanking Officer. We at Coriell are committed to ensuring the success of this phenomenal collection of aging-related biospecimens, and we are thrilled at the opportunity to continue this important collaboration with NIA.

The NIA Aging Cell Repository contains a collection of high quality, well characterized human and animal cell line and DNA samples, representing aged human populations, age-related diseases, and animal models of aging and has seen significant changes in the last decade.

One major focus of the collection is now to generate valuable induced pluripotent stem cell (iPSC) lines, which can be used to model aging and perform disease in a dish experiments. These stem cells are created from skin or blood cells in the NIA collection, which were reverted into a stem cell state. From there, these cells can be coaxed into becoming nearly any other cell type in the body, including neuronal or nerve cells. Seven of these important iPSC lines have been added to the collection in the last three years, representing age related neurodegenerative disorders like Alzheimers disease as well as rare genetic diseases like Progeria and Werner Syndrome.

Late last year, the Repository also added more than 350 new cell lines collected from participants in a long-term study of aging known as The 90+ Study. Participants in this study all aged 90 years or older donated their DNA and agreed to answer questions over a period of time to help researchers better understand the lifestyle and biological factors which may contribute to advanced aging.

Stem cells to help the heart – Science Magazine

Shinya Yamanaka's 2006 discovery of induced pluripotent stem cells (iPSCs) ignited a revolution in the field of stem cell biology (1). For the first time, nearly all human somatic tissues could be produced from iPSCs reprogrammed from blood or skin cells, in a process that took only weeks. This advance was particularly crucial for obtaining surrogate tissues from cell types that are otherwise difficult to procure and do not readily expand in vitro, such as cardiac or neural cells. Additionally, many ethical concerns are avoided, because this technology uses a patient's own genetic material to create iPSCs rather than relying on embryonic stem cells. In the aftermath of Yamanaka's discovery, entire biomedical industries have developed around the promise of using human iPSCs (hiPSCs) and their derivatives for in vitro disease modeling, drug screening, and cell therapy (2).

The hiPSC technology has had a particularly notable impact in cardiac regenerative medicine, a field where scientists and clinicians have been working to devise new methods to better understand how cardiovascular disease manifests and how to restore cardiovascular function after disease strikes (3). The heart is limited in its ability to regenerate lost cardiomyocytes (beating heart muscle cells), following an adverse event such as a heart attack (4). Cardiomyocytes derived from hiPSCs (hiPSC-CMs) may represent a potential replacement option for dead cells in such a scenario. However, certain issues remain to be addressed, such as whether hiPSC-CMs can integrate with host myocardial tissue in the long term (5).

While using hiPSC-CMs for in vivo cell therapy may become practical in the future, employing hiPSC-CMs for high-throughput drug discovery and screening is becoming a reality in the present (6). Cardiovascular diseases can be recapitulated in a dish with patient-specific hiPSC-CMs. For example, if a patient exhibits a cardiac arrhythmia caused by a genetic abnormality in a sarcomeric protein or ion channel, that same rhythm problem can be recapitulated in vitro (7). Thanks to advances in hiPSC differentiation protocols, hiPSC-CMs can now be mass-produced to study cardiovascular disease mechanisms in vitro (8).

My graduate thesis in the laboratories of Joseph Wu and Sean Wu at Stanford University focused on in vitro applications of hiPSC-CMs for cardiovascular disease modeling and for high-throughput screening of chemotherapeutic compounds to predict cardiotoxicity. I initially embarked on a project using hiPSC-CMs to model viral myocarditis, a viral infection of the heart, caused by the B3 strain of coxsackievirus (9). I began by demonstrating that hiPSC-CMs express the receptors necessary for viral internalization and subsequently found that hiPSC-CMs were highly susceptible to coxsackievirus infection, exhibiting viral cytopathic effect within hours of infection. I also identified compounds that could alleviate coxsackievirus infection on hiPSC-CMs, a translationally relevant finding, as there remains a shortage of treatments for viral myocarditis.

Using a genetically modified variant of coxsackievirus B3 expressing luciferase, I developed a screening platform for assessing the efficacy of antiviral compounds. Pretreatment with interferon-, ribavirin, or pyrrolidine dithiocarbamate markedly suppressed viral replication on hiPSC-CMs by activating intracellular antiviral response and viral protein clearance pathways. These compounds alleviated viral replication in a dose-dependent fashion at low concentrations without causing cellular toxicity.

I next sought to use hiPSC-CMs to screen anticancer chemotherapeutic compounds for their off-target cardiovascular toxicities (10). Cardiotoxicity represents a major cause of drug withdrawal from the pharmaceutical market, and several chemotherapeutic agents can cause unintended cardiovascular damage (11). Using cultured hiPSC-CMs, I evaluated 21 U.S. Food and Drug Administrationapproved tyrosine kinase inhibitors (TKIs), commonly prescribed anticancer compounds, for their cardiotoxic potential. HiPSC-CMs express the major tyrosine kinase receptor proteins such as the insulin, insulin-like growth factor (IGF), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) receptors, lending validity to this cellular model.

Initially, human induced pluripotent stem cells (hiPSCs) can be produced by reprogramming skin or blood cells by nonviral or viral reprogramming methods. Cardiac differentiation protocols allow for the creation of cardiomyocytes derived from hiPSCs (hiPSC-CMs) for downstream applications, including in vitro disease modeling, drug screening, and regenerative cell therapy.

With data from a battery of cellular apoptosis, contractility, electrophysiology, and signaling assays, I generated a cardiac safety index to help align in vitro toxicity data to clinical drug safety guidelines (12). From the safety index, I determined that a subclass of VEGF receptor 2/PDGF receptorinhibiting tyrosine kinase inhibitors, some of which exhibit toxicity clinically, also elicited cardiotoxicities in hiPSC-CMs. These manifested as substantial alterations in cellular electrophysiology, contractility, and viability when administered at clinically relevant concentrations. I also discovered that cotreatment with either IGF or insulin partially rescued TKI-induced toxicity by up-regulating antiapoptotic signaling pathways. This work could prove useful for groups aiming to develop effective screening platforms to assess new chemotherapeutic compounds for cardiotoxic side effects.

I also collaborated with the Center for the Advancement of Science in Space (CASIS) to send a sample of hiPSC-CMs to the International Space Station. As humankind ventures beyond our home planet, it is imperative that we better understand how the heart functions for long periods of time in microgravity. Analysis of these hiPSC-CMs revealed microgravity-induced alterations in metabolic gene expression and calcium handling (13).

In recent years, the stem cell field has experienced an explosion of studies using hiPSC-CMs as a model cellular system to study cardiovascular biology. As improvements in hiPSC-CM mass production continue, we will see a rise in studies using these cells for disease modeling and drug screening. Thus, although hiPSC-CM technology is in its infancy, it holds great potential to improve cardiovascular health.
