Overview of Intellia’s CRISPR/Cas9 Technology
These individual components by themselves are inactive but, when combined together and delivered to liver cells, they modify a specific DNAAcronym for deoxyribonucleic acid, the hereditary material in humans and almost all other organisms. DNA can be found in the cell nucleus and contains the genetic instructions for the development, functioning, growth and reproduction of all known organisms. Nearly every cell in a person’s body has the same DNA. sequence within the target gene. If this process happens in enough cells, the target gene may be permanently changed, leading to an impact on disease. The study currently underway is the first time a CRISPR/Cas9Adapted from a naturally occurring bacterial immune system, CRISPR is an acronym for Clustered Regularly Interspaced Short Palindromic Repeats. One of the proteins in the CRISPR system is known as CRISPR-associated 9 protein or Cas9 protein, which acts as a pair of ‘molecular scissors’ to cleave DNA. Researchers have co-opted the bacterial CRISPR/Cas9 system to make specific changes in the DNA of humans, other animals and plants. CRISPR/Cas9 was first harnessed in 2012 as a genome editing tool in the lab. More recently, scientists have begun engineering and testing CRISPR systems to be very specific to a desired genetic target. genomeA genome is an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than three billion DNA base pairs—is contained in all cells that have a nucleus. editing treatment will be delivered through a vein of the human body to edit genes.

What is a Clinical Trial?
A clinical trialA test of a new medical treatment or procedure in human volunteers with the purpose of evaluating a medical, surgical or behavioral intervention. Clinical trials typically follow preclinical (non-human) studies and are the primary way that clinical researchers and regulatory agencies evaluate whether a new treatment is safe and effective in people. is a research study conducted in human volunteers to test a potential treatment for safety, efficacy, dosing and more. A clinical trial also is the primary method to evaluate if a potential new therapy is safe and effective.
The number of participants is usually smaller in clinical trials for drugs that treat rare diseases. The clinical trial process typically follows four phases:
Why Volunteer to Participate?
Clinical trials are required in order to bring new treatments and therapies to market. These studies evaluate the effects of experimental treatment on patients and help researchers to better understand the disease, as well as its diagnosis, prevention and potential treatment options. Data from clinical trials also allow regulatory agencies to determine whether the drug or therapy is safe, effective and, ultimately, ready to be made available to the public.
Volunteer participants — whether healthy or patients with the disease — are vital to the success of clinical trials, especially those with rare diseases, as there may be a small number of people diagnosed with the disease. Clinical trial participation offers an opportunity to advance research and help bring new treatments one step closer to patients.
Enrollment
Clinical trials follow a defined protocol for how researchers will conduct the study based on criteria such as age, gender, disease severity and more. These protocols are reviewed and approved by health regulatory authorities in each country where a trial takes place. A screening process will be used to assess if potential participants meet the criteria for any Intellia-sponsored clinical trial. Some volunteers may not meet the eligibility criteria.
Informed Consent
Informed consentIn a clinical trial setting, informed consent means that patients considering volunteering to enroll receive information and consent to the purpose of the research, including their role and how the trial will work. Several healthcare team members will review an informed consent form with a volunteer prior to conducting study procedures. is a process used by researchers to ensure potential and enrolled patients are provided ample information about the clinical study. It is intended to protect volunteers by providing enough information so that they can understand all the risks, potential benefits and alternatives associated with the clinical study. The local coordinating investigator of each Intellia clinical trial will review this process with you.

Genome editing collectively refers to a set of technologies, including CRISPR/Cas9, that can be used to cut and modify DNA. Genome editing uses systems to make the DNA change inside the cell. These cells can be edited in the body (in vivo) or outside the body (ex vivo) from a patient or donor. tool in the lab. More recently, scientists have begun to make breakthroughs in the developments of new therapeutic treatment options for patients with chronic illnesses. Even though no treatments have yet to be approved as marketed products, several are in clinical trials.

Can CRISPR/Cas9 edit genes all throughout my body?

Genome editing collectively refers to a set of technologies, including CRISPR/Cas9, that can be used to cut and modify DNA. Genome editing uses systems to make the DNA change inside the cell. These cells can be edited in the body (in vivo) or outside the body (ex vivo) from a patient or donor. in somatic cellsNon-reproductive cells in the body. Most genetic diseases manifest in somatic cells. The DNA in these cells is non-heritable, which means that somatic cell genome editing affects only the patient and will not be genetically transmitted to future children. Examples of these types of cells are cells that make up the retina, liver, heart, etc. in the liver. In preclinical (non-human) studies, we observed that the target gene in the liver was edited, resulting in reduced production of the target protein. We also observed that circulating levels of protein produced by the target gene were permanently reduced throughout the body, except for in the eye and brain, which are closed systems.
Furthermore, the genes in somatic cells can only affect the cells of an individual’s own body. Our investigationalIn a research or clinical setting, investigational means that the drug has not been approved or authorized for use in patients outside of a clinical trial by any authority that regulates new treatments, such as the U.S. Food and Drug Administration (FDA) or United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA). treatments are focused on improving the health of the individual and not on future generations.
