Mayo Clinic Minute: What is CAR-T cell therapy? – Finger Lakes Times

Posted: October 13, 2022 at 2:21 am

Roughly 620,000 new cases of lymphoma were diagnosed worldwide, according to the World Cancer Research Fund International's 2020 report. Survival rates have improved as advances develop in treatment, such as chimeric antigen receptor-T cell therapy (CAR-T cell therapy).

CAR-T cell therapy is a personalized treatment giving hope to patients diagnosed with various lymphomas.

"Lymphoma in plain terms is essentially a cancer of your immune system," says Dr. Madiha Iqbal, a Mayo Clinic hematologist and oncologist.

Patients who are newly diagnosed with lymphoma are offered a combination of chemotherapy and antibody-based treatments. But for those who do not respond to two or more lines of such treatments, CAR-T cell therapy may be an option.

"Prior to the advent of CAR-T cell therapy, patients who had failed two lines of chemotherapy had a very poor survival of around six months," says Dr. Iqbal.

Receiving CAR-T cell therapy can take a few weeks as a patient's T cells, which normally help fight off infections, are collected and genetically engineered to target lymphoma.

After low-dose chemotherapy, the modified cells are infused back into the patient. These cells can then attack and destroy the lymphoma.

"Patients who had a very poor prognosis can now potentially be cured of their disease," says Dr. Iqbal.

Merck and Moderna Move Forward with Personalized Cancer Vaccine – BioSpace

Merck and Moderna are moving forward with a personalized cancer vaccine as Merckexercised its option to develop and commercialize mRNA-4157/V940, the companies announced Wednesday.

The option is based on an existing Collaboration and License Agreement originally inked in 2016 and amended in 2018.

The two companies will develop and commercialize mRNA-4157/V940 together. It is currently being tested by Moderna in a Phase II trial in combination with Mercks anti-PD-1 checkpoint inhibitor Keytruda (pembrolizumab) in the KEYNOTE-942 trial as adjuvant treatment for patients with high-risk melanoma. The trial has enrolled 157 patients.

After surgical resection, patients were randomized to receive 9 doses of the vaccine every three weeks and 200 mg of Keytruda or Keytruda alone every three weeks for about one year until disease recurrence or therapy-related toxicity forced them to stop.

Keytruda was chosen because it is the standard of care for this patient population. The primary endpoint is recurrence-free survival. Secondary endpoints include distant metastasis-free survival and overall survival. A data readout is expected before the end of the year.

PCVs are developed to stimulate the immune system so the patients own cells can create a specific antitumor response to their tumor mutation signature. mRNA-4157/V940 is engineered to stimulate an immune response by generating T-cell responses based on the patients mutational signature.

With data expected this quarter on PCV, we continue to be excited about the future and the impact mRNA can have as a new treatment paradigm in the management of cancer, stated Stephen Hoge, M.D., president of Moderna.

Under the deal, Merck will pay Moderna $250 million for the option. Merck will expense the payment in the third quarter of this year and include it in its non-GAAP financial results. The two companies will split costs and any profits equally under the global deal.

This long-term collaboration combining Mercks expertise in immuno-oncology with Modernas pioneering mRNA technology has yielded a novel tailored vaccine approach, stated Eliav Barr, M.D., SVP and head of global clinical development, CMO, Merck Research Laboratories.

Moderna vs. BioNTech

In April, John Haanen, M.D., Ph.D., of the Netherlands Cancer Institute (NCI) in Amsterdam, Netherlands, presented data from BioNTechs ongoing first-in-human Phase I/II trial of its own mRNA-based cancer vaccine. BNT211, a CAR-T cell therapy, is being investigated in patients with advanced solid tumors.

BNT211 consists of two drug products: an autologous CAR-T cell therapy targeting the oncofetal antigen Claudin-6 (CLDN6) and a CLDN6-encoding CAR-T cell amplifying RNA vaccine (CARVac). It uses BioNTechs mRNA-lipoplex technology, which is used in the COVID-19 vaccines developed with Pfizer. Tumor indications include testicular cancer, ovarian cancer, endometrial cancer, fallopian tube cancer, sarcoma and gastric cancer.

The trial data presented demonstrated 6 of 14 evaluable patients had a partial response, and 5 had stable disease with their target lesions shrinking. In addition to demonstrating overall target efficacy, the results were proof-of-concept of mRNA technology outside infectious diseases.

In addition to mRNA-4157/V940, Moderna also has a KRAS vaccine (mRNA-5671) and a checkpoint vaccine (mRNA-4359) along with others in the cancer space.

BioNTech and Regeneron Pharmaceuticals are collaborating on an mRNA vaccine for advanced melanoma, BNT111, which is in Phase II. Late last year, the FDA granted the vaccine fast-track designation based on available preclinical and clinical data showing the potential of BNT111 to overcome current limitations in the treatment of inoperable therapy-resistant advanced-stage melanoma.

First Patient With B-NHL or CLL Treated With MB-106 in Phase 1/2 Study – Targeted Oncology

Posted: October 13, 2022 at 2:21 am

The phase 1/2 clinical trial of MB-106 is demonstrating high efficacy, durable responses, and a favorable safety profile as the first patient treated did not experience cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome

The first patient has been treated in the phase 1/2 clinical trial (NCT05360238) evaluating the safety and efficacy of MB-106 in patients with relapsed or refractory B-cell non-Hodgkin lymphoma (B-NHL) and chronic lymphocytic leukemia (CLL), according to Mustang Bio, Inc.1

MB-106 is a CD20-targeted, autologous chimeric antigen receptor (CAR) T-cell therapy. The agent, which was developed by researchers at the Fred Hutchinson Cancer Research Center (Fred Hutc), is a third-generation CAR derived from a fully human antibody.

The patient treated with MB-106 did not experience cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS), leading the ongoing clinical trial of MB-106 to continue to elicit high efficacy, durable responses, and a favorable safety profile across wide range of hematologic malignancies.

The first clinical trial under Mustangs investigational new drug application is an important milestone in the ongoing development and evaluation of MB-106. Data presented at several prestigious medical meetings earlier this year from the initial, ongoing phase 1/2 clinical trial at Fred Hutch show that MB-106 continues to demonstrate high efficacy and a favorable safety profile across patients with a wide range of hematologic malignancies, said Manuel Litchman, MD, president and chief executive officer of Mustang Bio, Inc, in the press release, We look forward to providing updates on our multicenter MB-106 clinical trial as it progresses and anticipate reporting efficacy data in the fourth quarter of this year.

The multicenter, open-label, non-randomized, phase 1/2 study aims to evaluate the safety, tolerability, and efficacy of MB-106 in patients with relapsed or refractory B-NHL or CLL.2 However, the study is open to patients with a variety of selected CD20-expressing malignancies, including follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), and mantle cell lymphoma (MCL).

Part 1 of the study will enroll approximately 287 patients with aggressive B-NHL, including DLBCL, and MCL, as well as patients with indolent NHL like FLL. Patients with CLL of small lymphocytic lymphoma (SLL) will also be evaluated in this portion of the trial.

The phase 1 part of the study will administer patients escalating doses of MB-106 in a 3 + 3 study design. The coprimary end points are the incidence of treatment-emergent adverse events (TEAEs) in patients with relapsed or refractory CD20-positive B-NHL or CLL and to determine the recommended phase 2 dose of the agent. Secondary end points for phase 1 are ORR, duration of response (DOR), and minimal residual disease (MRD) in patients with CLL.

In the phase 2 portion of the study, patients with relapsed/refractory DLBCL, including those with MYC, BCL2, BCL6 rearrangement and primary mediastinal large B-cell lymphoma or transformed FL will be enrolled. Patients with B-NHL subtypes that progressed after available therapy, including MCL, marginal zone lymphoma, Waldenstrom macroglobulinemia, Burkitt-like lymphoma, hairy cell leukemia, and CLL/SLL will also be included.

For phase 2, the primary end point of the study is ORR with the secondary end points of DOR, the incidence of TEAEs, and the total number of patients with MRD in CLL.

Patients aged 18 years and older are eligible to enroll in the trial if they have relapsed after treatment with CD19 CAR-T cell therapy, have an ECOG performance status of 0-1, a life expectancy of 16 weeks, meet all laboratory criteria, adequate pulmonary function, and have left ventricular ejection fraction 50%. Further, all patients must be capable of consenting to treatment and be able to follow the visit scheduled and other protocol requirements. Female patients of childbearing potential must provide a negative pregnancy test, and patients of all genders must agree to use contraception for the duration of study.

Interim data from the initial 28 patients treated in the ongoing multicenter, open-label, non-randomized, phase 1/2 clinical trial continue to support the use of MB-106 in B-NHLs and CLL.

Interim data as of September 9, 2022, show the agent to elicit an overall response rate (ORR) of 96% and complete response (CR) rate of 75% in heatologic malignancies, including follicular lymphoma, CLL, diffuse large B-cell lymphoma, and Waldenstrom macroglobulinemia

A total of 12 patients have experienced CR for more than 12 months with 10 ongoing and 4 patients have had a CR for more than 2 years. The longest CR currently seen in a patient in the trial is 33 months. Further, 6 patients had a partial response which improved to a CR. All of these patients remain in ongoing CR. Among the 3 patients previously treated with CD19 CAR T-cell therapy, all have responded to treatment with MB-106.

Regarding safety, MB-106 has shown a favorable safety profile as an outpatient therapy so far with no patients having grade 3 or higher CRS or ICANS. CAR T-cell persistence results in deepening responses following initial 28-day assessments.

Enrollment in this clinical trial of MB-106 is ongoing and data from the study is expected to be released at the end of 2022.

We are excited to broaden the evaluation of MB-106 with this multicenter clinical trial under Mustangs IND. To date, the data from the initial, ongoing clinical trial at Fred Hutch continue to demonstrate a high rate of complete and durable responses, said Mazyar Shadman, MD, MPH, study chair, associate professor and physician at Fred Hutch and University of Washington, in the press release. In addition, MB-106 has shown potential to treat patients in an outpatient setting and provide another immunotherapy option for patients treated previously with CD19-directed CAR T-cell therapy.

Iovance Biotherapeutics Announces First Patient Dosed with PD-1 Inactivated Tumor Infiltrating Lymphocyte (TIL) Therapy – GlobeNewswire

Posted: October 13, 2022 at 2:21 am

First Genetically Modified (TALEN-edited) Iovance TIL Therapy with Inactivated PD-1 Expression

SAN CARLOS, Calif., Oct. 10, 2022 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a late-stage biotechnology company developing novel T cell-based cancer immunotherapies, announced that the first patient was dosed, and completed the safety observation period, in the IOV-GM1-201 trial of Iovances genetically modified, PD-1 inactivated TIL therapy, IOV-4001. IOV-GM1-201 is a Phase 1/2, first-in-human study investigating the safety and efficacy of IOV-4001 in patients with previously treated metastatic non-small cell lung cancer (NSCLC) or advanced melanoma.

Friedrich Graf Finckenstein, M.D., Chief Medical Officer of Iovance, stated, Dosing the first patient with IOV-4001 is an important first step in providing proof-of-concept for delivering genetically modified TIL therapy to solid tumor patients with significant unmet needs and few treatment options. We look forward to dosing the next patient. This trial may also support our broader platform of genetically modified Iovance TIL therapies to potentially address difficult-to-treat solid tumor cancers.

To inactivate the gene coding for the PD-1 protein, IOV-4001 utilizes the gene-editing TALEN technology licensed from Cellectis (Euronext Growth: ALCLS - NASDAQ: CLLS), a clinical-stage biotechnology company using its pioneering gene-editing platform to develop potentially life-saving cell and gene therapies. This single genetic modification in IOV-4001 may enhance the antitumor activity of the TIL mechanism to directly target and kill tumor cells.

Jason Chesney, M.D., Ph.D.,Director and Endowed Professor, UofL Health Brown Cancer Center, University of Louisville, and an IOV-GM1-201 principal investigator, stated, I am excited about the potential for gene-editing to open new doors for TIL therapy in patients with solid tumor cancers that do not respond well to current treatment options. As the first multicenter clinical trial to investigate a genetically modified TIL therapy, the IOV-GM1-201 trial may pave the way for a promising new treatment approach to cancer.

PD-1 is a checkpoint protein found on T cells that normally acts as an off switch to help to prevent T cells from attacking other cells in the body. It works by binding to PD-L1, a protein found on both normal and cancerous cells, thereby shutting down an attack by a T cell. As a TIL therapy that is genetically modified to remove this important barrier for T cells to attack cancer, IOV-4001 has the potential to become an optimized, next generation TIL therapy for several solid tumor cancers. A poster on preclinical data was presented at the American Association for Cancer Research (AACR) 2022 Annual Meeting.

IOV-GM1-201 is actively enrolling adult participants with advanced NSCLC or unresectable or metastatic melanoma. For more information, eligibility criteria, and trial locations, please visit http://www.clinicaltrials.gov (NCT05361174) or contact clinical.inquiries@iovance.com.

AboutIovance Biotherapeutics, Inc.Iovance Biotherapeutics aims to be the global leader in innovating, developing and delivering tumor infiltrating lymphocyte (TIL) cell therapies for patients with cancer. We are pioneering a transformational approach to cure cancer by harnessing the human immune systems ability to recognize and destroy diverse cancer cells in each patient. Our lead late-stage TIL product candidate, lifileucel for metastatic melanoma, has the potential to become the first approved one-time cell therapy for a solid tumor cancer. The Iovance TIL platform has demonstrated promising clinical data across multiple solid tumors. We are committed to continuous innovation in cell therapy, including gene-edited cell therapy, that may extend and improve life for patients with cancer.

About the iTANK platform

The iTANK- (immunoTherapies Activated with NAP for efficient Killing) platform is the company's own fully developed technology platform for arming and enhancing CAR T-cells to meet two of the major challenges CAR T-cell therapies face in the treatment of solid tumors: tumor antigen heterogeneity and a hostile tumor microenivornment. The technology is used to incorporate a transgene into CAR T-cells encoding a neutrophil activating protein (NAP) from the bacterium Helicobacter pylori. Upon activation, NAP secreted from the CAR(NAP) T-cells has been shown to be able to enhance the function of the CAR T-cell in addition to activating a parallel immune response via CD8+ killer T-cells. This is expected to lead to a broad attack against most antigen targets on cancer cells. The iTANK-platform is used to enhance the company's own CAR T-cells but can also be universally applied to other CAR T-cell therapies under development. More information about iTANK-platform is available here: https://www.elicera.com/technology

Glowing embryonic gecko hand and otherworldly slime mold amaze in winning microscope photos – Livescience.com

Posted: October 13, 2022 at 2:19 am

Shots of a stunningly detailed embryonic gecko hand, an otherworldly slime mold and a psychedelically stained segment of dinosaur bone are among some of the intricate and awe-inspiring entries in a recent microscopic photography contest.

The Nikon Small World Photomicrography Competition, which has been running for almost 50 years, is a specialist event that blends "science and artistry under the microscope," organizers said in a statement (opens in new tab). The contest, which highlights the beauty of incredibly small things, is open to anyone as long as the images are captured using a light microscope. This year's top 20 images were revealed by event organizers on Oct. 11.

Grigorii Timin, a doctoral student at the University of Geneva in Switzerland, won first prize at this year's competition with a painstakingly curated shot of a developing gecko hand stained with fluorescent dyes. Captured under the supervision of Michel Milinkovitch, an evolutionary geneticist at the University of Geneva, the winning picture is a composite of thousands of individual images that have been stitched together.

"The scan consists of 300 tiles, each containing about 250 optical sections, resulting in more than two days of acquisition and approximately 200 GB of data," Timin said in the statement. The developing lizard's hand is around 0.12 inch (3 millimeters) long, which is a massive subject to capture with microscopic detail, he added.

Researchers stained the gecko's nerves with a cyan-tinted dye and colored the reptile's bones, tendons, ligaments, skin and blood cells in warmer colors like yellow and orange. Zooming in on particular regions of the image reveals how "structures [within the hand] are organized at a cellular level," Timin said.

However, the multi-colored gecko hand was not the only image that stole the show at this year's competition.

Alison Pollack, a California-based photographer who specializes in macro and extreme macro photography, won 5th place with a stunning shot of a slime mold from the genus Lamproderma. The iridescent blue structure, which looks like some sort of alien tree, is the organism's reproductive fruiting body. However, like all slime molds, the strange specimen is one individual cell with no internal membranes and multiple nucleuses dotted throughout its body. The image is also a composite, this time of more than 100 images stitched together.

"Despite the rather unflattering common name, slime molds are astonishingly beautiful organisms," Pollack told Live Science in an email. "While they grow in almost any kind of environment all over the world, they are little known because they are so tiny."

This particular slime mold was collected by Pollack from a leaf just outside her home after heavy rainfall. The best place to look for slime molds is in woodland areas after it has rained, Pollock said. Anyone can go hunting for the bizarre creatures, but "unless you have very good eyes, they are best found with the aid of a light and a good magnifying lens," she added.

Randy Fullbright, a photographer based near the Dinosaur National Monument in Utah, took 13th place with a boldly colored shot of a dinosaur bone fragment stained yellow and blue. The bone likely belonged to a sauropod a group of large dinosaurs with long tails and necks, such as Brachiosaurus and Diplodocus and was uncovered at a ranch at the Morrison Formation in northwest Colorado, which dates back to around 150 million years ago toward the end of the Jurassic period, Fullbright told Live Science in an email. The specimen was cut using a diamond saw, and the minerals within the bone were stained different colors, he added.

"I feel very blessed for the opportunity to show a world that most will never see," Fullbright said.

Tenth place in the competition went to Murat ztrk, a Turkish photographer based in Ankara, with a breathtaking shot of a fly trapped under the chin of a tiger beetle. The fly appears to be struggling to escape the beetle's death grip the beetle is sticking its mandibles, or serrated mouthparts, into its prey's eyes.

Tiger beetles, which are a subfamily of ground beetles known as Cicindelinae, are the fastest-running insects on Earth. The fastest tiger beetle species, Rivacindela hudsoni, can run at around 5.6 mph (9km/h), which is around 120 times its own body length per second. In 2014, a study published in the journal Proceedings of the Royal Society B (opens in new tab), showed that, at this speed, R. hudsoni becomes functionally blind while running and relies on its antennae to see its prey instead of using its eyes.

Past winners of Nikon's Small World competition include a helix-shaped plankton, a mosquito's heart and a fluorescent, rainbow-colored turtle embryo.

On Sept. 13, the winners of Nikon's Small World in Motion competition the sister competition that focuses on the very best microscopic videos produced by scientists and photographers announced its winners. The standout video was a "completely hypnotic" donut of swirling cell microtubules.

Editor's note: This article was updated Oct.12 at 4:35 a.m. ET to correct the age of the dinosaur bone fragment following new information received from the photographer.

Researchers develop method to study brain connectivity, functionality – Florida Hospital News and Healthcare Report – South Florida Hospital News

Research method integrates human cortical organoids into developing rat brains, allowing for study of brain processes associated with disease.

This work provides a significant advance in the ability of scientists to study the cellular and circuit underpinnings of complex human brain disorders. It allows organoids to get wired in a more biologically relevant context and function in ways they cant do in a petri dish, said David Panchision, Ph.D., chief of the Developmental and Genomic Neuroscience Research Branch in the Division of Neuroscience and Basic Behavioral Science at NIMH.

ResearcherSergiu Pasca, M.D.(link is external), and colleagues at Stanford University, Stanford, California, demonstrated that a cortical organoid cultured from human stem cells can be transplanted ontoand integrated intothe developing rat brain to study certain developmental and functional processes. The findings suggest that transplanted organoids may offer a powerful tool for investigating the processes associated with disease development.

Researchers sometimes use cortical organoidsthree-dimensional cultures of human stem cells that can mirror some of the developmental processes seen in typical brainsas a model for investigating how some aspects of the human brain develops and functions. However, cortical organoids lack the connectivity seen in typical human brains, limiting their usefulness for understanding complex brain processes. Researchers have been trying to overcome some of these limitations by transplanting individual human neurons into adult rodent brains. While these transplanted neurons connect with rodent brain cells, they do not become fully integrated due to the developmental limitations of the adult rat brain.

In this study, the team of researchers advanced the use of brain organoids for research by transplanting an intact human cortical organoid into a developing rat brain. This technique creates a unit of human tissue that can be examined and manipulated. The researchers used methods previously pioneered in the Pasca lab to create cortical organoids using human-induced pluripotent stem cellscells derived from adult skin cells that have been reprogrammed into an immature stem-cell-like state. They then implanted these organoids onto the rat primary somatosensory cortex, a part of the brain involved in processing sensation.

The researchers did not detect any motor or memory abnormalities or abnormalities in brain activity in the rats that received the transplanted organoid. Blood vessels from the rat brain successfully supported the implanted tissue, which grew over time.

To understand the extent to which the organoids could integrate into the rat somatosensory cortex, the researchers infected a cortical organoid with a viral tracer that spreads through brain cells as an indicator of functional connections. After transplanting the marked organoid onto the rats primary somatosensory cortex, researchers detected the viral tracer in multiple brain areas, such as the ventrobasal nucleus and the somatosensory cortex. In addition, the researchers observed new connections between the thalamus and the transplanted area. These connections were activated using electrical stimulation and stimulation of the rats whiskers, indicating that they were receiving meaningful sensory input. Moreover, the researchers were able to activate human neurons in the transplanted organoid to modulate the rats reward-seeking behavior. The findings suggest functional integration of the transplanted organoid into specific brain pathways.

Structurally and functionally, after seven to eight months of growth, the transplanted brain organoid resembled neurons from human brain tissue more than human organoids maintained in cell culture. The fact that the transplanted organoids mirrored the structural and functional features of human cortical neurons led the researchers to wonder if they could use transplanted organoids to examine aspects of human disease processes.

The promise of this platform is not only in identifying what molecular processes underlie the advanced maturation of human neurons in living circuits and leveraging it to improve conventionalin vitromodels, but also in providing behavioral readouts for human neurons, said Dr. Pasca.

To examine this, the researchers generated cortical organoids with cells from three participants with a rare genetic disorder associated with autism and epilepsy calledTimothy syndromeand three participants without any known diseases and implanted them onto the rat brain. Both types of organoids integrated into the rat somatosensory cortex, but organoids derived from Timothy Syndrome patients displayed structural differences. These structural differences did not appear in organoids that were created from the cells of patients with Timothy Syndrome and maintained in cell culture.

These experiments suggest that this novel approach can capture processes that go beyond what we can detect with currentin vitromodels, said Dr. Pasca. This is important because many of the changes that cause psychiatric disease are likely subtle differences at the circuit level.

Organoids: science fiction or the future of pre-clinical studies? – Lexology

Posted: October 13, 2022 at 2:16 am

New technologies based on human cells are increasingly seen as key to reducing the time and cost in bringing drugs to market. This is an evolving area of study, though the field itself, which developed out of study into 3D cell architecture, is not new. These approaches replicate human physiology to study diseases, treatments, and for drug-development purposes. In parallel to major advances made from a medical and scientific standpoint, novel legal and ethical questions arise.

The definition of organoid is problematic and covers a range of cell culture techniques. Scientists have developed ways of culturing organ-specific tissue from human stem cells or progenitor cells to re-create important aspects of the 3D anatomy e.g. the pancreas, kidney, liver, thyroid, retina, and brain, to recapitulate key organ features. A list of definitions can be found at the end of this article.

A potential game-changer

Breakthroughs in stem cell technology and tissue engineering are driving the change. In addition to this, trends in other areas, like cell and gene therapy and personalised medicine have acted as catalysts. By simulating organ function, specific disease states can be modelled and studied. This is especially useful when looking at rare diseases, how tissue and microbiota interact, or how drugs interact with each other.

The use of organoids holds great promise in several medical-scientific areas like disease modelling, precision medicine, and transplantation. One of the most notable possibilities is to supplement or to a certain extent replace animal models during pre-clinical studies in drug development.

The field is at an early stage, but the trend is an upward one. Companies involved are seeing increasing demand for their services from pharma, biotech, research and academic institutes as well as the cosmetics industry. According to a recent market report the annual growth rate is set to increase by 37.4% during 2022-2028. Cambridge-based CN Bio recently doubled the size of its laboratory facilities due to demand. In the US, Hesperos Inc., a contract research organisation (CRO) provides a multi-organ chip platform (Human-on-a-Chip) based in Florida filed for a USD 20 million IPO. Another fascinating company is Labskin, who make full thickness human skin models, providing reproduceable results for microbiome research. Labskin just announced the first ever commercially available pigmented skin-equivalent in a joint project with Bradford University. These new models incorporate melanocytes, the cells that give skin its colour and present a huge opportunity to study melanomas.

The need for new and/or updated regulatory frameworks

For the use of these new models to be considered by regulatory authorities across the globe in the evaluation of safety and efficacy of drugs (subject to valid scientific demonstrations), regulatory frameworks will have to be adapted on a jurisdiction-by-jurisdiction basis.

In the US, the FDA Modernization Act of 2021 has been introduced to amend the Federal Food, Drug, and Cosmetic Act. The amendment strikes animal and inserts nonclinical tests or studies to be used in the evaluation of safety and efficacy of drugs, such as MPS, cell-based assays and computer models. In addition, the FDA recently approved the first clinical trial using efficacy data collected from a microphysiological system. More data may be needed to convince regulators, but the impetus - and interest - is there.

In the EU, is a 3-year Science With and For Society (SwafS) project, funded under HORIZON2020. The project is being coordinated by the University of Oslo, Norway and involves major research institutions across the EU. It is currently being carried out with the objective of developing a comprehensive regulatory framework for organoid research and organoid-related technologies. In the meantime, the European Parliament is working on legislation aimed at reducing the number of animal studies. The European Medicines Agency already recognized that organoids and organ-on-chip may become suitable alternatives to animal models during medicines development, in its wider effort to promote the 3R principles (replace, reduce and refine).

Further legal and ethical challenges to be addressed

The use of organoids and other MPS raises critical legal and ethical issues, which must be urgently addressed to allow their wide-spread utilization as part of pre-clinical studies within an acceptable framework.

In particular, since organoids are grown from human cells, initial donors rights must be respected and efficiently enforced. The original cells may come from foetal or adult tissues they may be pluripotent stem cells (PSCs), adult stem cells taken from specific tissues and reengineered somatic cells. Key challenges notably relate to the donors informed consent, (which issue has already been addressed by many scholars), research on human embryos and data protection issues. Complete anonymity of human tissue has been shown to be neither possible (due to the identifiable nature of DNA) nor desirable (as the data is necessary to validate prediction models). The donor must be able to control, to some extent, the subsequent use of his/her samples; in practice, consent may not be easily withdrawn (or with very limited effect) once organoids have been successfully developed and used in a pre-clinical study.

Strong quality standards should further be developed and complied with when it comes to producing organoids for pre-clinical purposes. Indeed, a set of specifications for the production of human 3D organoids used as medicines has been proposed. One could imagine specific guidelines applicable to the production of organoids for drug development purposes, to ensure consistent production methods as well as reliability as pre-clinical models. This calls for a wider systemic approach as to the regulation of human tissue and cells intended for human versus research application. On this point, it is interesting to note that a proposal for a regulation on standards of quality and safety for substances of human origin intended for human application is currently being examined in the EU, which expressly excludes their use in research that does not involve application to the human body.

Moreover, specific issues are triggered depending on the type of laboratory-cultivated model. For instance, the development of human cerebral organoids raises questions in terms of moral status and legal protection. Indeed, studies suggest that developed neuronal models show complex electrical activity the human cerebral organoids (sometimes referred to as mini-brains) can command a muscle connected thereto, be receptive to stimuli and may even exhibit a rudimentary form of consciousness. This raises questions as to the core definition of human being and, from a legal standpoint, personhood, the beginning and end of life, as well as the legal protection that should be awarded to such in vitro models (how they can be engineered, used, destroyed etc). In addition, the existence of sophisticated sentient models creates uncertainty regarding what moral status should be awarded to them. These issues are particularly complex as legal, ethical, philosophical, societal and political aspects are necessarily intertwined, and the way they are addressed may greatly vary from one jurisdiction to another.

Further legal and ethical challenges should be addressed in connection with the production and use of organoids beyond pre-clinical studies such as their potential patentability, their commercialization (while certain countries like France forbids the commercialization of human products and elements), their use for transplantation, the articulation with regulations on genome editing, chimeras and human cloning etc.

Conclusion

The rapid progress of scientific research around organoids and other MPS bears the potential to revolutionize many aspects of medical and pharmaceutical research. In particular, they hold great promise in the pursuit of a suitable (and potentially more reliable) alternative to the use of animal models in pre-clinical studies. Beyond this, legal and ethical challenges should be addressed in connection with the production and use of organoids in other applications such as their potential patentability, their commercialization (while certain countries like France forbids the commercialization of human products and elements), their use for transplantation, and the articulation with the regulations on genome editing, the creation of chimeras and human cloning.

Definitions:

Microphysiological systems (MPS): an umbrella term for organ-on-chip (OOC), organoids or tumoroids (stem cells grown in a dish).

Organ-on-a-chip (OOC): from the field of microfluidics, a multi-channel 3-D cell culture. An integrated circuit that simulates the activities, mechanics and physiological response of an entire organ or an organ system.

Organoid: means resembling an organ. Organoids are defined by three characteristics. The cells arrange themselves in vitro into three-dimensional organization that is characteristic for the organ in vivo, the resulting structure consists of multiple cells found in that particular organ and the cells execute at least some of the functions that they normally carry out in that organ.
