What is gene therapy used for?

Most gene therapies are still in the clinical trial phase. Clinical trials play an important role in finding treatments that are safe and effective. Clinical trials are investigating gene therapy for the treatment ofcancer,macular degenerationand other eye diseases, certaingenetic conditionsandHIV/AIDS.

The U.S. Food and Drug Administration (FDA) has approved two gene therapies for use in the U.S.:

Is gene therapy safe?

The first gene therapy trial was run more than thirty years ago. The earliest studies showed that gene therapy could have very serious health risks, such as toxicity, inflammation, and cancer. Since then, researchers have studied the mechanisms and developed improved techniques that are less likely to cause dangerous immune reactions or cancer. Because gene therapy techniques are relatively new, some risks may be unpredictable; however, medical researchers, institutions, and regulatory agencies are working to ensure that gene therapy research, clinical trials, and approved treatments are as safe as possible.

Comprehensive federal laws, regulations, and guidelines help protect people who participate in research studies (called clinical trials). The U.S. Food and Drug Administration (FDA) regulates all gene therapy products in the United States and oversees research in this area. Researchers who wish to test an approach in a clinical trial must first obtain permission from the FDA. The FDA has the authority to reject or suspend clinical trials that are suspected of being unsafe for participants.

The National Institutes of Health (NIH) also plays an important role in ensuring the safety of gene therapy research. NIH provides guidelines for investigators and institutions (such as universities and hospitals) to follow when conducting clinical trials with gene therapy. These guidelines state that clinical trials at institutions receiving NIH funding for this type of research must be registered with the NIH Office of Biotechnology Activities. The protocol, or plan, for each clinical trial is then reviewed by the NIH Recombinant DNA Advisory Committee (RAC) to determine whether it raises medical, ethical, or safety issues that warrant further discussion at a RAC public meeting.

An Institutional Review Board (IRB) and an Institutional Biosafety Committee (IBC) must approve each gene therapy clinical trial before it can be carried out. An IRB is a committee of scientific and medical advisors and consumers that reviews all research within an institution. An IBC is a group that reviews and approves an institution's potentially hazardous research studies. Multiple levels of evaluation and oversight ensure that safety concerns are a top priority in the planning and carrying out of gene therapy research.

The clinical trial process occurs in three phases. Phase I studies determine if a treatment is safe for people and identify its side effects. Phase II studies determine if the treatment is effective, meaning whether it works. Phase III studies compare the new treatment to the current treatments available. Doctors want to know whether the new treatment works better or has fewer side effects than the standard treatment. The FDA reviews the results of the clinical trial. If it determines that the benefits of the new treatment outweigh the side effects, it approves the therapy, and doctors can use it to treat a disorder.

What are CAR T cell therapy, RNA therapy, and other genetic therapies?

Several treatments have been developed that involve genetic material but are typically not considered gene therapy. Some of these methods alter DNA for a slightly different use than gene therapy. Others do not alter genes themselves, but they change whether or how a genes instructions are carried out to make proteins.

Cell-based gene therapy

CAR T cell therapy (or chimeric antigen receptor T cell therapy) is an example of cell-based gene therapy. This type of treatment combines the technologies of gene therapy and cell therapy. Cell therapy introduces cells to the body that have a particular function to help treat a disease. In cell-based gene therapy, the cells have been genetically altered to give them the special function. CAR T cell therapy introduces a gene to a persons T cells, which are a type of immune cell. This gene provides instructions for making a protein, called the chimeric antigen receptor (CAR), that attaches to cancer cells. The modified immune cells can specifically attack cancer cells.

RNA therapy

Several techniques, called RNA therapies, use pieces of RNA, which is a type of genetic material similar to DNA, to help treat a disorder. In many of these techniques, the pieces of RNA interact with a molecule calledmessenger RNA(or mRNA for short). In cells, mRNA uses the information in genes to create a blueprint for making proteins. By interacting with mRNA, these therapies influence how much protein is produced from a gene, which can compensate for the effects of a genetic alteration. Examples of these RNA therapies include antisense oligonucleotide (ASO), small interfering RNA (siRNA), and microRNA (miRNA) therapies. An RNA therapy called RNA aptamer therapy introduces small pieces of RNA that attach directly to proteins to alter their function.

Epigenetic therapy

Another gene-related therapy, called epigenetic therapy, affectsepigenetic changesin cells. Epigenetic changes are specific modifications (often called tags) attached to DNA that control whether genes are turned on or off. Abnormal patterns of epigenetic modifications alter gene activity and, subsequently, protein production. Epigenetic therapies are used to correct epigenetic errors that underlie genetic disorders.

Vector Insights

The AAV segment shows a significant revenue contribution of 22.9% in 2023. Several biopharma companies are offering their viral vector platform for the development of AAV-based gene therapy product. For instance, in September 2016, Lonza signed an exclusive agreement with Massachusetts Eye and Ear to support its novel Anc-AAV gene therapy platform for development and commercialization of next-generation gene therapies based on their AAV platform. Similarly, RegenxBio had made an agreement with companies AveXis & Biogen in March 2014 and May 2016, respectively, which would allow both companies to use RegenxBios AAV vector platform for development of gene therapy molecules. Furthermore, in May 2021, Biogen Inc. and Capsigen Inc. entered into a strategic research partnership to engineer novel AAV capsids that have the possibility to deliver transformative gene therapies, which can address the fundamental genetic causes of numerous neuromuscular and CNS disorders. In July 2021, the U.S. Department of Commerces National Institute of Standards and Technology (NIST), National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL), and United States Pharmacopeia (USP) announced a collaboration to evaluate analytical methods and develop standards for AAV. As part of this partnership, NIST and USP will be conducting an interlaboratory study in which several laboratories will measure these serious quality attributes, and their results will be linked and examined. This collaboration will support the development of new promising gene therapies that will significantly advance peoples lives.

Indication Insights

The spinal muscular atrophy (SMA) segment dominated the market in 2023. Although SMA is a rare disorder, it is one of the most common fatal inherited diseases of infancy. The development of Zolgensma (AVXS-101), has proven its effectiveness in treating SMA and altering the phenotype of the illness. The FDA approved Novartis' Zolgensma approval in May 2019, which is aimed at treating the underlying cause of SMA. As of now, Zolgensma is the only gene treatment in this field to have been approved. The approval of this gene therapy is evidence of the growing use of therapies to treat serious hereditary illnesses like SMA.

The Beta-Thalassemia Major/SCD segment is anticipated to register the fastest CAGR over the forecast period. Gene therapy for SCD and -thalassemia is based on transplantation of gene-modified hematopoietic stem cells. Clinical and preclinical studies have shown the efficacy and safety of this therapeutic modality. However, several other factors, such as suboptimal gene expression levels & gene transfer efficiency, limited stem-cell dose and quality, and toxicity of myeloablative regimens are still hampering its efficacy. Despite these challenges, in June 2019, bluebird Bios Zynteglo (formerly LentiGlobin) received conditional approval in Europe for the treatment of -thalassemia and is expected to receive U.S. FDA approval in August 2022. Moreover, the product has already received Orphan Drug status by the U.S. FDA for treatment of patients with sickle cell disease (SCD). Furthermore, in April 2021, Vertex Pharmaceuticals and CRISPR Therapeutics amended partnership for the development, production, and commercialization of CTX001 in sickle beta thalassemia and cell disease. These achievements in this segment are anticipated to significantly boost the adoption of the product in this segment.
