U.S. Gene Therapy Market Growth

The gene therapy market includes DNA-based therapies involving the delivery of a functional copy of a defective gene or the correction of a mutated gene. DNA-based therapies are delivered using various methods such as viral vectors, plasmids, or gene editing tools. The robust gene therapy pipeline is expected to boost the market growth in the forecast period. Researchers are working to make gene therapy available at clinics. Various universities and institutes have a broad portfolio of products in the pipeline, which, in turn, is expected to boost revenue generation in the future.

The COVID-19 pandemic has had a notable impact on the U.S. gene therapy industry. While the market for gene therapies is expected to grow significantly in the years ahead, the pandemic caused some delays in clinical trials. Nevertheless, the pandemic also highlighted the importance of gene therapy in preventing and treating diseases, which could lead to increased investment and funding for the field. Despite the challenges posed by the pandemic, the U.S. gene therapy industry remains poised for growth and innovation in the future.

Technological advancements in gene editing, viral vector development, and delivery mechanisms have propelled gene therapy from the realms of speculation to clinical application. Innovations like CRISPR-Cas9 technology have revolutionized gene editing, allowing for precise modifications in genetic sequences with unprecedented accuracy and efficiency. Similarly, advancements in viral vectors, including adeno-associated viruses (AAVs) and lentiviruses, have enhanced the delivery of therapeutic genes to target cells, improving the efficacy and safety of gene therapy treatments.

An increase in funding and investments in gene therapy advancements is expected to provide lucrative growth opportunities to market players. For instance, in January 2022, Ori Biotech raised more than USD 100 million in a Series B funding to introduce a novel cell & gene therapy developing platform. This funding allowed for a rapid transition from precommercialization to market launch. In October 2023, NIH granted nearly USD 40 million to Yale School of Medicine which would support the development of phase 2 CRISPR-based gene therapy platform which would directly target genetic brain diseases such as H1-4 (HIST1H1E) syndrome and Angelman syndrome.

U.S. Gene Therapy Market Report Scope

Indication Insights

Based on indication, the market is segmented into Large B-cell lymphoma, multiple myeloma, spinal muscular atrophy (SMA), acute lymphoblastic leukemia (ALL), melanoma (lesions), inherited retinal disease, beta-thalassemia major/SCD, and others. The Large B-cell lymphoma segment held the largest revenue share of 36.14% in 2023. Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin Lymphoma (NHL) subtype. It is estimated to account for around 30%-40% of all cases. For instance, in May 2018, the U.S. FDA approved Kymriah for the treatment of adult patients with refractory or relapsed large B-cell lymphoma, including DLBCL.

The inherited retinal disease segment is expected to register a significant CAGR over the forecast period. An increase in R&D activities for the development of gene therapies for treating ocular diseases, including inherited retinal disease, has driven the segment. For instance, a therapy for the treatment of patients with Leber congenital amaurosis (LCA) using AAV to deliver the gene for human RPE65 to the retinal pigment epithelium is currently in phase 3 clinical trial which is expected to complete in 2029.

Vector Type Insights

Based on vector type, the market is segmented into retrovirus & gamma retrovirus, lentivirus, AAV, adenovirus, modified herpes simplex virus, and others. The lentivirus dominated with a revenue share of 43.79% in 2023. Gene therapy viral vectors extracted from lentiviruses offer many advantages over conventional gene vectors like retrovirus such as ability to provide stable and long-term gene expression, ability to induct themselves to non-dividing cells, possible generation of replication adept lentiviruses during vector preparation, and many more. This contributes to the segment’s growth, thus driving its dominance in the market. In December 2023, a numerous randomized clinical trial was started to evaluate OTL-203 (gene therapy) and stem cell transplant (standard of care) in individuals affected with MPS-IH (Hurler syndrome), is using lentivirus. This clinical trial is expected to be complete at the start of 2031. Thus, the rising usage of lentivirus in clinical trials is anticipated to boost the growth of the segment.

The AAV segment is expected to grow at a highest CAGR over the forecast period. This is attributed to the increasing demand due to the result from clinical trials pertaining to development of ocular and orthopedic gene therapy treatment exhibiting increased efficacy and efficiency. Moreover, the growing number of clinical trials and R&D activities are further anticipated to contribute to the growth of the segment over the forecast period. For instance, an ongoing clinical trial of AAV5-hRKp.RPGR vector for participants with X-linked retinitis pigmentosa uses AAV as their vector which is proposed to get completed by the end of 2029.

Route Of Administration Insights

Based on route of administration, the market is segmented into intravenous and others. The intravenous segment dominated the market share in 2023 and is anticipated to grow at a higher CAGR over the forecast period. Intravenous administration typically involves shorter treatment durations and less invasive procedures compared to alternative routes such as intramuscular or subcutaneous injections. This increases the convenience and reduces the discomfort for patients thereby improving the treatment adherence and overall patient satisfaction, driving preference for intravenous gene therapy products.

The others segment is expected to grow at a significant CAGR over the forecast period. This segment includes transcutaneous, subretinal, topical, and intravitreal routes of administrations. RGX-314 is being developed as a unique one-time gene therapy for the treatment of patients with neovascular age-related macular degeneration (wet AMD) which is expected to be completed by 2026. Thus, the rising number of clinical trials is expected to drive the growth of the market.
