The global cancer gene therapy market size was accounted for USD 2.95 billion in 2023 and it is increasing around USD 18.11 billion by 2033 with a CAGR of 19.9% from 2024 to 2033, according to a new report by Nova One Advisor.

Cancer Gene Therapy Market Overview

Cancer is a group of diseases that involve abnormal cell growth which can spread to respective parts of the body. Cancer can spread throughout the human body.Gene therapyis a kind of treatment in which the genes that are not normal or are missing in the patients cells are replaced with normal genes. Cancer gene therapy is a technique for treating cancers where the therapeutic DNA is introduced in the gene of the individual suffering from cancer.

Due to a high success rate in preclinical as well asclinical trials, cancer gene therapy is gaining high popularity all over the world. There are numerous techniques utilized in cancer gene therapy. In one of the gene therapy techniques, either the mutated gene is replaced with a healthy gene, or the gene is inactivated if its function is abnormal. In a newly developed technique, new genes can be introduced in the body of the patient to help fight against cancer cells.

Further, the ongoing extensive research and development (R&D) strategies implemented bybiopharmaceuticalfirms for producing novel therapeutic drugs are driving the market growth notably.

The market players can aim towards expansions, collaborations, joint ventures, acquisitions, and partnerships to advance capabilities in gene therapy. This would help in yielding effective therapeutic drugs for treating different kinds of cancers. In April 2022, GSK plc announced the acquisition of Sierra Oncology for 1.6 billion ($1.9 billion). This acquisition would help GSK plc in enhancing its capabilities with respect to targeted therapies for treating rare forms of cancer.

Biotechnologyfirms are evaluating novel gene therapy vectors for increasing levels of protein production/gene expression, reducing immunogenicity, and improving durability.

The top cancers in terms of the count of new cases in 2020 all over the world were Lung Cancer (2,206,771 cases),Breast Cancer(2,261,419 cases),Prostate Cancer(1,414,259 cases), Colorectal Cancer (1,931,590 cases), Stomach Cancer (1,089,103 cases), and Liver cancer (905,677 cases). In 2018, there were around 134,632 new cancer cases and 89,042 cancer-related fatalities. Breast and liver cancers were among the most common tumors in terms of incidence and mortality. The high prevalence of breast cancer cases enhances the scope for CRISPR/Cas9-based gene editing for breast cancer therapy and VISA-claudin4-BikDD gene therapy.

Types of gene therapy for cancer

Gene therapy aims tocontrolthe altered genesor genetic mutationsof a cancertoprevent the cancers growth.This approach to using our own cells and genes to treat cancer is called somatic gene therapy.Thistype of gene therapydoes not impact germ-line cells in the reproductive system, meaning none of the genetic changescan bepassedon to otherfamily members.

There are four types of somatic gene therapy: gene editing; gene replacement; gene addition; and gene inhibition.

Gene editing is correcting the cells gene to fix the imbalance by snipping out the faulty part of the gene and changing the cancers DNA. This type of gene therapy may correct the alteration rather than trying to remove it. Gene replacement is just that: replacing the faulty or nonworking gene with a healthy copy of it. This type of gene therapy is another form of trying to fix the genetic change rather than trying to remove it.

Gene addition is adding novel genetic code to a different cell usually an immune system fighter cell to help it combat the protein linked to the damaged gene. CAR T-cell therapy is an example of gene addition. This form of gene therapy isnt adding a copy of an already-existing gene but rather an entirely new gene usually with the intent of killing the cancer cell via the immune system. Doctors may also add a new gene directly to the cancer cell that causes the cancer cell to commit apoptosis (kill itself).

Gene inhibition simply shuts down the faulty gene. This can either kill the cell or prevent it from acting in a cancerous manner, such as growing and replicating exponentially.

Steps of gene therapy

Gene therapy is a new and potentially curative approach to treating cancer, but researchers still have so much to learn. While the steps below may seem straightforward, each part of the process requires years of study to develop the technologies.

Researchers must first identify the gene and protein linked to the cancer. The next steps are:

Steps of CAR T-cell therapy

CAR T-cell therapy has a slightly different process than more direct forms of gene therapy. CAR T cells are lab-generated fighter cells with specific, anti-cancer genetic code. Adding this genetic code is the gene therapy component of CAR T-cell therapy. CAR stands for chimeric antigen receptor, which is the new genetic code added to the T cells.

There are six CAR T-cell therapy agents approved by the U.S. Food and Drug Administration for different blood cancers. These approvals validate CAR T cells as an effective form of cancer gene therapy to improve patient life expectancy.

Doctors first draw blood from a patient and separate the T cells, which are white blood cells leading the immune systems defense against viruses, diseases and more unwanted intruders. T cells aim to protect the body from cancer, but theyre often ineffective at doing so.

The process of drawing blood from patients and separating the T cells is called apheresis.

After removing T cells from the body, the steps of CAR T-cell therapy are:

A similar process occurs for CAR NK-cell therapy. Scientists create chimeric antigen receptors to strengthen natural killer (NK) cells, another white blood cell of the immune system.

How long does CAR T-cell therapy take?

There are six CAR T-cell therapies approved for types of three blood cancers: myeloma, leukemia and lymphoma. CAR T-cell therapy infusions can take place in an inpatient or outpatient care setting, but the patient must be closely monitored at all times.

CAR T-cell therapy can lead to side effects, most notable cytokine release syndrome.

The entire CAR T-cell process lasts approximately one month, not including the recovery time after treatment:

For the first seven days after receiving the CAR T-cell infusion, patients must remain under medical supervision. For weeks 2-4 of the post-infusion timeline, patients must remain within a short drive of their medical facility to respond to any issues.

The total recovery period from CAR T-cell therapy is usually 2-3 months following infusion, according to the Dana-Farber Cancer Institute.

There are several studies for CAR T-cell therapies for cancer. Participating in a clinical trial helps advance cell and gene therapy research and can advance much-needed therapies to more patients in need.

Therapy Insights

Gene induced immunotherapy dominated the market with a revenue share of over 41.9% in 2023. The dominance of the segment can be attributed to research studies aiming to lower the proliferation of various types of cancer by strengthening the immune system. Many gene therapies for cancers are designed on the basis of immunotherapy elements. For instance, PROVENGE (by Dendreon Corporation) is an autologous cellular immunotherapy designed to stimulate a subjects immune system against prostate cancer.

Oncolytic virotherapy is expected to grow at the fastest rate over the forecast period owing to the favorable outcomes and the level of efficacy offered by oncolytic virotherapy. Oncolytic viruses can combat cancer cells without disturbing the healthy cells in vicinity by stimulating natural killer cells. Moreover, there are lucrative research grants for the research on oncolytic virotherapy. For instance, in July 2022, the researchers at the Center for Nuclear Receptors and Cell Signaling at the University of Houston received a USD 1.8 million grant from the National Institutes of Health to work on oncolytic virotherapy.

End-use Insights

Biopharmaceutical companies led the market with a revenue share of over 50.0% in 2023. This is attributed to the increasing global prevalence of different types of cancers owing to various hereditary, environmental, and lifestyle risk factors. Moreover, the market is driven by increasing adoption of elemental gene therapy options by biopharmaceutical giants to design cancer therapeutic regimes. Many novel therapeutic drugs are under different phases of trials and firms are striving to market them in different regions across the globe. For instance, in January 2020, bluebird bio, Inc. launches its drug, ZYNTEGLO in Germany to be used as a one-time gene therapy solution for patients aged 12 years and above.

The biopharmaceutical companies segment is projected to grow at the fastest rate over the forecast period. The increasing global prevalence of malignant tumors is a key factor driving the market. Moreover, an increased interest in oncology therapeutics research and development is resulting in a rise in the number of FDA approvals of gene therapy drugs. For instance, there are 6 FDA-approved cancer gene therapy drugs with Tecratus, Abcema, and Kymriah being the recent approvals.

Cancer Gene Therapy Industry is Rising Rapidly Up to USD 18.11 Bn by 2033 - BioSpace

Greater use of CRISPR-based therapies in clinical trials is expected to drive further advancements in precision medicine, GlobalData states.

There has been a notable rise in licensing agreements for innovator drugs incorporating clustered regularly interspaced short palindromic repeats (CRISPR)-based technology for gene therapies over the past five years, according to data and analytics firm GlobalData.

These agreements have amassed a total deal value of $21 billion. Of note, between 2020 to 2022, there was a remarkable surge in deal worth. For agreements relating to or involving treatments for haematological disorders, the total deal value reached $1.8 billion, the research found.

For instance, the approval of Casgevy in the US in December 2023 signified a breakthrough in gene therapy. Vertex Pharmaceuticals treatment was subsequently the first CRISPR/Cas9 gene-edited therapy to be granted a marketing authorisation by the European Commission (EC) in February 2024.

Innovator drugs harnessing CRISPR technologies saw 182 percent growth in total licensing agreement deal value from $5.6 billion in 2020 to $15.8 billion in 2022. Among the top three therapy areas, oncology represented over half of the total deal value with $11.9 billion, followed by immunology with $6.7 billion, and central nervous system with $2.2 billion, Ophelia Chan, Business Fundamentals Analyst at GlobalData explained.

GlobalData highlighted that the largest CRISPR-based deal of 2023 was Eli Lilys subsidiary, Prevail Therapeutics gaining rights to Scribe Therapeuticss CRISPR X-Editing (XE) technologies. In a deal potentially worth over $1.57 billion, the agreement seeks to advance in vivotherapies for targets that cause serious neurological and neuromuscular diseases.

CRISPR technologies fuelling haematological innovations - European Pharmaceutical Review

CRISPR technology offers the promise to cure human genetic diseases with gene editing. This promise became a reality when the worlds first CRISPR therapy was approved by regulators to treat patients with sickle cell disease and beta-thalassemia last year.

American biopharma Vertex Pharmaceuticals CASGEVY works by turning on the BCL11A gene, which codes for fetal hemoglobin. While this form of hemoglobin is produced before a baby is born, the body begins to deactivate the gene after birth. As both sickle cell disease and beta-thalassemia are blood disorders that affect hemoglobin, by switching on the gene responsible for fetal hemoglobin production, CASGEVY presents a curative, one-time treatment for patients.

As CASGEVYs clearance is a significant milestone, the technology has come a long way. CRISPR/Cas9 was first used as a gene-editing tool in 2012. Over the years, the technology exploded in popularity thanks to its potential for making gene editing faster, cheaper, and easier than ever before.

CRISPR is short for clustered regularly interspaced short palindromic repeats. The term makes reference to a series of repetitive patterns found in the DNA of bacteria that form the basis of a primitive immune system, defending them from viral invaders by cutting their DNA.

Using this natural process as a basis, scientists developed a gene-editing tool called CRISPR/Cas that can cut a specific DNA sequence by simply providing it with an RNA template of the target sequence. This allows scientists to add, delete, or replace elements within the target DNA sequence. Slicing a specific part of a genes DNA sequence with the help of the Cas9 enzyme, aids in DNA repair.

This system represented a big leap from previous gene-editing technologies, which required designing and making a custom DNA-cutting enzyme for each target sequence rather than simply providing an RNA guide, which is much simpler to synthesize.

CRISPR gene editing has already changed the way scientists do research, allowing a wide range of applications across multiple fields. Here are some of the diseases that scientists aim to tackle using CRISPR/Cas technology, testing its possibilities and limits as a medical tool.

Cancer is a complex, multifactorial disease, and a cure remains elusive. There are hundreds of different types of cancer, each with a unique mutation signature. CRISPR technology is a game-changer for cancer research and treatment as it can be used for many things, including screening for cancer drivers, identifying genes and proteins that can be targeted by cancer drugs, cancer diagnostics, and as a treatment.

China spearheaded the first in-human clinical trials using CRISPR/Cas9 as a cancer treatment. The study tested the use of CRISPR to modify immune T cells extracted from a patient with late-stage lung cancer. The gene-editing technology was used to remove the gene that encodes for a protein called PD-1 that some tumor cells can bind to to block the immune response against cancer. This protein found on the surface of immune cells is the target of some cancer drugs termed checkpoint inhibitors.

CRISPR technology has also been applied to improve the efficacy and safety profiles of cancer immunotherapy, such as CAR-T cell and natural killer cell therapies. In the U.S., CRISPR Therapeutics is one of the leading companies in this space, developing off-the-shelf, gene-edited T cell therapies using CRISPR, with two candidates targeting CD19 and CD70 proteins in clinical trials.

In 2022, the FDA granted Orphan Drug designation to Intellia Therapeutics CRISPR/Cas9-gene-edited T cell therapy for acute myeloid leukemia (AML). Currently, Vor BioPharmas VOR33 is undergoing phase 2 trials to treat AML, and the CRISPR trial is one to watch, according to a report published by Clinical Trials Arena earlier this year.

However, CRISPR technology still has limitations, including variable efficiency in the genome-editing process and off-target effects. Some experts have recommended that the long-term safety of the approach remain under review. Others have suggested using more precise gene-editing approaches such as base editing, an offshoot of CRISPR that hit the clinic in the U.S. last year.

There are several ways CRISPR could help us in the fight against AIDS. One is using CRISPR to cut the viral DNA that the HIV virus inserts within the DNA of immune cells. This approach could be used to attack the virus in its hidden, inactive form, which is what makes it impossible for most therapies to completely get rid of the virus.

The first ever patient with HIV was dosed with a CRISPR-based gene-editing therapy in a phase 1/2 trial led by Excision Biotherapeutics and researchers at the Lewis Katz School of Medicine at Temple University in Philadelphia back in 2022.

The decision to move the therapy to the clinic was bolstered by the success of an analog of the drug EBT-101 called EBT-001 in rhesus macaques infected with simian immunodeficiency virus (SIV). In a phase 1/2 study, EBT-101 was found to be safe.

Another approach could make us resistant to HIV infections. A small percentage of the worlds population is born with a natural resistance to HIV, thanks to a mutation in a gene known as CCR5, which encodes for a protein on the surface of immune cells that HIV uses as an entry point to infect the cells. The mutation changes the structure of the protein so that the virus is no longer able to bind to it.

This approach was used in a highly controversial case in China in 2018, where human embryos were genetically edited to make them resistant to HIV infections. The experiment caused outrage among the scientific community, with some studies pointing out that the CRISPR babies might be at a higher risk of dying younger.

The general consensus seems to be that more research is needed before this approach can be used in humans, especially as recent studies have pointed out this practice can have a high risk of unintended genetic edits in embryos.

Cystic fibrosis is a genetic disease that causes severe respiratory problems. Cystic fibrosis can be caused by multiple different mutations in the target gene CFTR more than 700 of which have been identified making it difficult to develop a drug for each mutation. With CRISPR technology, mutations that cause cystic fibrosis can be individually edited.

In 2020, researchers in the Netherlands used base editing to repair CFTR mutations in vitro in the cells of people with cystic fibrosis without creating damage elsewhere in their genetic code. Moreover, aiming to strike again with yet another win is the duo Vertex Pharmaceuticals and CRISPR Therapeutics, which have collaborated to develop a CRISPR-based medicine for cystic fibrosis. However, it might be a while until it enters the clinic as it is currently in the research phase.

Duchenne muscular dystrophy is caused by mutations in the DMD gene, which encodes for a protein necessary for the contraction of muscles. Children born with this disease experience progressive muscle degeneration, and existing treatments are limited to a fraction of patients with the condition.

Research in mice has shown CRISPR technology could be used to fix the multiple genetic mutations behind the disease. In 2018, a group of researchers in the U.S. used CRISPR to cut at 12 strategic mutation hotspots covering the majority of the estimated 3,000 different mutations that cause this muscular disease. Following this study, Exonics Therapeutics was spun out to further develop this approach, which was then acquired by Vertex Pharmaceuticals for approximately $1 billion to accelerate drug development for the disorder. Currently, Vertex is in the research stage, and is on a mission to restore dystrophin protein expression by targeting mutations in the dystrophin gene.

However, a CRISPR trial run by the Boston non-profit Cure Rare Disease targeting a rare DMD mutation resulted in the death of a patient owing to toxicity back in November 2022. Further research is needed to ensure the safety of the drug to treat the disease.

Huntingtons disease is a neurodegenerative condition with a strong genetic component. The disease is caused by an abnormal repetition of a certain DNA sequence within the huntingtin gene. The higher the number of copies, the earlier the disease will manifest itself.

Treating Huntingtons can be tricky, as any off-target effects of CRISPR in the brain could have very dangerous consequences. To reduce the risk, scientists are looking at ways to tweak the genome-editing tool to make it safer.

In 2018, researchers at the Childrens Hospital of Philadelphia revealed a version of CRISPR/Cas9 that includes a self-destruct button. A group of Polish researchers opted instead for pairing CRISPR/Cas9 with an enzyme called nickase to make the gene editing more precise.

More recently, researchers at the University of Illinois Urbana-Champaign used CRISPR/Cas13, instead of Cas9, to target and cut mRNA that codes for the mutant proteins responsible for Huntingtons disease. This technique silences mutant genes while avoiding changes to the cells DNA, thereby minimizing permanent off-target mutations because RNA molecules are transient and degrade after a few hours.

In addition, a 2023 study published in Nature went on to prove that treatment of Huntingtons disease in mice delayed disease progression and that it protected certain neurons from cell death in the mice.

With CASGEVYs go-ahead to treat transfusion-dependent beta-thalassemia and sickle cell disease in patients aged 12 and older, this hints that CRISPR-based medicines could even be a curative therapy to treat other blood disorders like hemophilia.

Hemophilia is caused by mutations that impair the activity of proteins that are required for blood clotting. Although Intellia severed its partnership with multinational biopharma Regeneron to advance its CRISPR candidate for hemophilia B a drug that was recently cleared by the FDA to enter the clinic the latter will take the drug ahead on its own.

As hemophilia B is caused by mutations in the F9 gene, which encodes a clotting protein called factor IX (FIX), Regenerons drug candidate uses CRISPR/Cas9 gene editing to place a copy of the F9 gene in cells in order to get the taps running for FIX production.

The two biopharmas will continue their collaboration in developing their CRISPR candidate to treat hemophilia A, which manifests as excessive bleeding because of a deficit of factor VIII. The therapy is currently in the research phase.

While healthcare companies were creating polymerase chain reaction (PCR) tests to screen for COVID-19 in the wake of the pandemic, CRISPR was also being put to use for speedy screening. A study conducted by researchers in China in 2023, found that the CRISPR-SARS-CoV-2 test had a comparable performance with RT-PCR, but it did have several advantages like short assay time, low cost, and no requirement for expensive equipment, over RT-PCRs.

To add to that, the gene editing tool could fight COVID-19 and other viral infections.

For instance, scientists at Stanford University developed a method to program a version of the gene editing technology known as CRISPR/Cas13a to cut and destroy the genetic material of the virus behind COVID-19 to stop it from infecting lung cells. This approach, termed PAC-MAN, helped reduce the amount of virus in solution by more than 90 percent.

Another research group at the Georgia Institute of Technology used a similar approach to destroy the virus before it enters the cell. The method was tested in live animals, improving the symptoms of hamsters infected with COVID-19. The treatment also worked on mice infected with influenza, and the researchers believe it could be effective against 99 percent of all existing influenza strains.

As European, U.S., and U.K. regulators have given their stamp of approval for the first-ever CRISPR-based drug to treat patients, who is to say we wont see another CRISPR-drug hitting this milestone in the near future.

And apart from the diseases mentioned, CRISPR is also being studied to treat other conditions like vision and hearing loss. In blindness caused by mutations, CRISPR gene editing could eliminate mutated genes in the DNA and replace them with normal versions of the genes. Researchers have also demonstrated how getting rid of the mutations in the Atp2b2 and Tmc1 genes helped partially restore hearing.

However, one of the biggest challenges to turn CRISPR research into real cures is the many unknowns regarding the potential risks of CRISPR therapy. Some scientists are concerned about possible off-target effects as well as immune reactions to the gene-editing tool. But as research progresses, scientists are proposing and testing a wide range of approaches to tweak and improve CRISPR in order to increase its efficacy and safety.

Hopes are high that CRISPR technology will soon provide a way to address complex diseases such as cancer and AIDS, and even target genes associated with mental health disorders.

Seven diseases that CRISPR technology could cure - Labiotech.eu

One of the most significant challenges in treating HIV is the virus ability to integrate its genome into the hosts DNA. This means that lifelong antiretroviral therapy is essential as latent HIV can reactivate from reservoirs as soon as treatment ends.

One potential technique being developed to address this problem is the use of gene editing technology to cut out and incapacitate HIV from infected cells. Currently, there is a Phase I/II Clinical Trial underway in people with HIV-1 (the most common strain of HIV)

Now, new research from another team shows that gene editing can be used to eliminate all traces of the HIV virus from infected cells in the laboratory.

The research is being presented early ahead of the European Congress of Clinical Microbiology and Infectious Diseases, which will be held from 27-30 April in Barcelona, Spain. Its been carried out by scientists from the Amsterdam Medical University in the Netherlands, and the Paul Ehrlich Institute in Germany, and has not yet been submitted for peer review.

Our aim is to develop a robust and safe combinatorial CRISPR-Cas regimen, striving for an inclusive HIV cure for all that can inactivate diverse HIV strains across various cellular contexts, they write in a conference abstract submitted ahead of ECCMID.

CRISPR-Cas gene editing technology acts like molecular scissors to cut DNA and either delete unwanted genes or introduce new genetic material, while guidance RNA (gRNA) tells CRISPR-Cas exactly where to cut at designated spots on the genome.

In this research, the authors used 2 gRNAs that target conserved parts of the viral genome this means they remain the same or conserved across all known HIV strains. This genetic sequence does not have a match in human genes, to prevent the system going off target and causing mutations elsewhere in the human genome.

The hope is to one day provide a broad-spectrum therapy capable of combating multiple HIV variants effectively. But before this dream can become a reality, the researchers had to address a number of issues with getting the CRISPR-Cas reagents into the right cells.

To delivered CRISPR components into cells in the body a viral vector, containing genes that code for the CRISPR-Cas proteins and gRNA, is used. This is the vehicle that delivers into the host cell the instructions to make all necessary components, but these instructions need to be kept as simple and short as possible.

Another issue is making sure the viral vector enters HIV reservoir cells specifically cells that express the receptors CD4+ and CD32a+ on their surface.

They found that in one system, saCas9, the vector size was minimised, which enhanced its delivery to HIV-infected cells. They also included proteins that target the CD4+ and CD32a+ receptors specifically in the vector.

This system showed outstanding antiviral performance, managing to completely inactivate HIV with a single guide RNA (gRNA) and excise (cut out) the viral DNA with two gRNAs in cells in the lab.

We have developed an efficient combinatorial CRISPR-attack on the HIV virus in various cells and the locations where it can be hidden in reservoirs and demonstrated that therapeutics can be specifically delivered to the cells of interest, the authors write.

These findings represent a pivotal advancement towards designing a cure strategy.

But the researchers stress that, while these preliminary findings are very encouraging, it is premature to declare that there is a functional HIV cure on the horizon.

How CRISPR-Cas genome editing could be used to cure HIV - Cosmos

CRISPR gene editing technology is beginning to deliver on a promise to quickly create crops with traits that withstand a changing climate, resist aggressive pests and reinvigorate healthy soils, according to experts at the South by Southwest event in Austin earlier this month.

Companies exploring CRISPR to make climate-friendly foods and medicines are enjoying some tailwinds:

At the same time, startups and researchers are taking on investment partnerships with larger organizations to commercialize CRISPR innovations. Bayer has a project with Pairwise to create a corn crop that is more resilient to environmental factors. In 2011, The Gates Foundation gave a $10.3 million grant to the International Rice Research Institute (IRRI) and has re-invested more than $16 million to the organization in 2023 to create climate resistant rice varieties.

The past 200 years of industrialized agriculture have increased yields and eased shipping with large, durable produce often to the detriment of the soil, the planet and taste.

"We think with gene editing you wont have to make that choice," said Tom Adams, CEO of Pairwise. The startup is producing the first CRISPR consumer product by editing out the wasabi-like spiciness of a mustard green to make it more palatable to eaters.

Pairwise sold the green at a New York grocer earlier this year and is seeking to partner with companies to sell to consumers. The companys main focus is developing business-to-business markets by selling ingredient crops or seeds to big agricultural companies or seed banks.

Traditionally, farmers mated or cross-pollinated organisms to augment their desired characteristics. It could take decades to cultivate a plant to the desired enhancement for human consumption.

In the 1970s, scientists began genetically modifying organisms (GMOs) by cultivating foreign DNA in a bacteria or virus and then inducing those cells to add their modified DNA into a plant or animal. The modified DNA would typically offer resistance to pests or diseases.

CRISPR opens up new possibilities to modify crops by knocking out or enhancing genes that are already present. "Its more precise, and more accurate and more intuitive than breeding," said Elena Del Pup, a plant genetics researcher at Wageningen University in the Netherlands. "[It] allows us to make very specific edits."

"The hope and the promise of [CRISPR] is that by making a few simple edits, you confer a highly valuable disease resistance trait onto a crop," said Vipula Shukla, senior program officer at the Bill and Melinda Gates Foundation.

If European Union states eventually accept the recent parliamentary vote, they would exempt plants with CRISPR edits from GMO labeling requirements.

The EU has been notoriously strict on GMOs, requiring labeling under consumer "right to know" rules since 1997. Every GMO product must receive EU authorization and a risk assessment.

In the United States, the FDA began requiring clear labeling on consumer products containing GMOs in 2022. In 2018, the USDA decided that CRISPR-edited foods do not need to be regulated or labeled as genetically edited because these modifications could have been done with traditional breeding alone.

Experts think the new EU vote that exempts CRISPR from these rules indicates a willingness to embrace new tools to address the challenges of providing enough food for a growing population facing climate change.

Heres how advocates foresee CRISPR helping the food system become more resilient to climate change.

In agriculture, maximizing yield remains a top priority. Crops that produce more food and use less fertilizer, water and pesticides also decrease embedded emissions.

Pairwise, in collaboration with Bayer, is editing corn that yields more kernels per ear. Another edited corn grows to 6 feet rather than the conventional 9 feet tall.

"The advantage is that it's much sturdier," said Adams. "So if there's a big wind it doesn't get blown over." It also makes applying insecticides, fungicides and herbicides easier.

To engineer the next generation of climate-efficient plants, scientists need to find specific genes in them, such as for controlling water usage or nitrogen fixation.

"One of the biggest limitations [for CRISPR] is our relatively limited knowledge of the biology of the organisms that were trying to edit," Shukla said. "You can't apply CRISPR to a gene if you don't know what the gene does."

Farmers and researchers are field-testing a strain of CRISPR-edited rice designed to resist bacterial blights, which can kill 75 percent of a crop. Rice blight is a particular problem in India and Africa.

Since 2011, The Gates Foundation has been funding field trials of CRISPR rice in India. It has engaged in similar field tests of a virus-resistant corn in Mexico since 2015. "The Gates Foundation wants to come in at a point where there's a testable hypothesis," Shukla said. "We're focusing on developing and delivering these innovations to people."

The foundation looks for preliminary laboratory results or small scale, proven field testing. It then funds a larger scale pilot in real-world conditions in developing countries.

"I don't personally have a lot of faith that we're going to reverse climate change," Adams said. "So, I think we probably should be investing in adapting to it."

Farmers need plants that can survive temperature extremes, including higher nighttime temperatures, as well as erratic rainfall patterns. CRISPR can help native plants adapt to their changing environment by enhancing their genes.

"One of the consequences of climate change is having to move crops into places they havent been before because it's warmer or wetter or drier," Shukla said. "And crops are not adapted to those pests [in the new locations]. We have the ability with gene editing to confer traits that make those crops more tolerant to pests and diseases that they haven't experienced before."

The Gates Foundation is looking at genes for heat tolerance as its next target for research and investment, according to Shukla.

CRISPR technology may also diversify the genetic composition of current crops and domesticate new crops. That could help address the damage done by industrial, monoculture farming practices, in which a single crop species dominates a field or farm, depleting the soil of its nutrients.

"Wild relatives of plants contain traits that can be super-valuable for agriculture," Shukla said. "But we haven't had a way through crossing or other methods to bring those traits into the agricultural system."

If Pairwises mild mustard green becomes a hit, it might offer an incentive for farmers to plant a new leafy green alongside their kale, lettuce and spinach adding to biodiversity.

The CI AdvantageStability, Safety, And Security

We have a proven track record of financial security and stability, as well as price stability. CI is the only cryonics organization with no debt, no stockholders, and no landlords. We own our patient care facilities outright, and all of our member officers and directors donate their services voluntarily. Were one of the oldest cryonics organizations in existence and the only such organization that has never raised its prices, even in high-inflation times like the late 70s and early 80s. Adjusting for inflation, our prices have actually steadily declined, and we hope to continue that trend.

As members, each and every one of us has a vested interest in the long-term viability of our organization our facilities, cryostats and finances are built to last into the future were striving toward.

We have a flexible and rapid system of emergency patient care based on widely available networks of mortuary assistance. This means that in the critical early stages, we can bring qualified professionals to you throughout most of the world. In particular, London-based F.A. Albin & Sons funeral directors are trained, practiced, equipped, and prepared to fly a team anywhere in Europe on short notice to help European CI members, tourists or business travellers.

Our prices are lower than any other organization in fact, the most affordable prices anywhere in the world. This is in keeping with our membership philosophy to provide ourselves reliable cryonic services at a reasonable and affordable cost. If we were to raise prices, wed only be charging ourselves more.

Our minimum whole-body suspension fee is $28,000. (For members at a distance, transportation costs and local help will be additional.) Our $28,000 fee is a one-time only payment, with no subsequent charges.Its easily funded by insurance or other means. (For last-minute cases, where the patient was not signed up beforehand, we ordinarily charge $35,000 rather than $28,000, if arrangements can be worked out at all.)

Does that lower fee mean lower quality patient care or services?Absolutely not.We believe that our non-profit status allows us to more successfully control costs. We believe that specific methods and research offered by alternative cryonics organizations differ only slightly from ours and that our procedures and policies give an equal or better chance for patient survival than competing organizations.

See for yourself. Read ourFAQand review The CI Advantage. Remember, many CI members could afford the higher prices of other organizations for themselves and their families, but weve chosen CI because we know its our best bet. And yours.

About CI - The Cryonics Institute

1976 ROBERT ETTINGER FOUNDS THE CRYONICS INSTITUTE

Then in 1976 a separate organization was formed: the Cryonics Institute, to offer cryostasis services: careful preparation, cooling, and long term patient care in liquid nitrogen.

Our goal was maximum reliability and affordability. And we achieved it. The Cryonics Institute offers clear-cut advantages over all other providers. Such as:

Our prices are lower than any other organization in fact, the most affordable prices anywhere in the world. Our minimum whole-body suspension fee is $28,000. (For members at a distance, transportation costs and local help will be additional.) Our $28,000 fee is a one-time only payment, with no subsequent charges. Its easily funded by insurance or other means, and funds the best care available for our member patients. (For last-minute cases, where the patient was not signed up beforehand, we ordinarily charge $35,000 rather than $28,000, if arrangements can be worked out at all.)

Does that lower fee mean lower quality patient care or services? No. The major part of other organizations fees are earmarked for investment provisions totally unrelated to patient care and preparation. Methods and research differ, but overall we believe our procedures and policies give a better chance for patient survival than any other organizations and this web site will show you the detailed reasons why.

See for yourself. Read our FAQ and see The CI Advantage that compares the different cryonics organizations and why we think CI gives you and those you love the best possible chance for future survival. Remember: most CI members can afford the higher prices of other organizations for themselves and their families and often do give more, in bequests and donations. But weve chosen CI because we know its our best bet. And yours.

We have a unique, proven track record of financial security and stability. Price stability too. CI is the only organization with no debt, no stockholders, and no landlords. We own our patient care facilities outright, and all our officers and directors donate their services voluntarily. Were one of the oldest cryonics organizations in existence and the only such organization that has never raised its prices, even in high-inflation times like the late 70s and early 80s. Adjusting for inflation, our prices have actually steadily declined, and we expect this to continue.

Financially, we are the soundest cryonics organization in existence.

We have a uniquely flexible and rapid system of emergency patient care based on universally available networks of mortuary assistance (and often medical assistance). This means that in the critical early stages, we can bring qualified professionals to you faster than any other system to you, and to travelers, vacationers, and members throughout most of the world. In particular, London-based F.A. Albin & Sons funeral directors are trained, practiced, equipped, and prepared to fly a team anywhere in Europe on short notice to help European CI members or tourists and business travelers.

And finally, we provide a comprehensive source of information here on CIs website. The site youre reading will lead you to everything you need to know about the subject of cryonics, and more. It offers you free information, free books, the latest news, hundreds of links to thousands of sources covering health, science, cutting-edge medicine, nanotechnology, financial help and resources, and supportive people and organizations. And if thats not enough? We personally will answer any question you might have about cryonics or the Cryonics Institute directly by email, or direct you to someone who can. In the world of cryonics, this is the source to visit, and the place to be.
