The gene therapy market is projected to be worth USD 17.3 billion in 2035, growing at a CAGR of 18%, during the period 2022-2035, claims Roots Analysis

Given the potential of gene therapies to permanently cure a diverse array of clinical conditions at the genetic level, the current pipeline is rapidly growing; a number of such therapies are currently being evaluated in late stages of development

Roots Analysis has announced the addition of “Gene Therapy Market” report to its list of offerings.


Post the emergence of blockbuster gene therapies, such as ZOLGENSMA® (for spinal muscular atrophy type I) and Libmeldy™ (for metachromatic leukodystrophy), this domain has garnered significant interest in the medical community. Moreover, considering the promising trial results of pipeline candidates, notable players have made investments to support product development and commercialization efforts.

Key Market Insights


Over 1,150 gene therapies are currently being developed across different stages

Apart from 11 approved products, most of the aforementioned therapies (70%) are in early stages of development (preclinical / discovery), while the rest are being evaluated in clinical trials. It is worth mentioning that more than 40% of the clinical stage candidates target oncological diseases. Further, majority of such therapies (66%) use adenovirus vectors as molecular carriers.


More than 250 companies claim to be engaged in the development of gene therapies, globally

In the past decade, over 160 companies have been established in this domain. Of the total, 60% of the players are small firms. In addition, majority (62%) of these gene therapy developers are based in North America, primarily in the US.


290+ clinical trials evaluating gene therapies have been registered, worldwide

Of the total number of trials registered during the period 2015-2020, close to 10% have already been completed, while 56% are presently recruiting patients. Further, presently, around 55% of the trials are evaluating therapy candidates in phase II studies.           


USD 8.5+ billion has been invested by both private and public investors, since 2015

The maximum funding amount was raised through secondary offerings (40%), venture capital (28%) and IPOs (16%), during the period 2015-2022. Interestingly, majority (77%) of the funding instances were reported by players based in North America.


Over 5,800 patents have been filed / published related to gene therapies, since 2017

Around 90% of the total number of patent applications were related to gene therapies, while the remaining were focused on gene editing-based therapies. Further, majority of the patent assignees were industry players. However, it is worth mentioning that the contribution of non-industry players in the overall patent filing activity has increased considerably (CAGR of 19%), over the past few years.


Merger and acquisition activity in this market has grown at a CAGR of 22%, during 2015-2021

It is worth mentioning that, across most of the instances (43%) both the acquirer and the acquired company were based in North America. Moreover, majority of the acquisitions (26%) were focused on providing access to novel platform / technology, followed by acquisitions undertaken for therapeutic area consolidation (24%) and drug class consolidation (24%).


The overall market is anticipated to grow at a CAGR of over 18%, during the period 2022-2035

Gene therapies based on gene augmentationcurrently represent a significant share of the market, and this trend is unlikely to change in the foreseen future, as several such candidates are being evaluated in late stages. North America (primarily the US) is expected to capture 60% of the market share by 2035, in terms of the sales-based revenues.
