To date, 54 RMAT (Regenerative Medicine Advanced Therapy) designations have been publicly announced. However, the FDA states it has received 170 requests and issued 64, which means that a handful are not yet public knowledge.
Sponsors of cell and gene therapies are eligible to obtain an RMAT designation from the U.S. FDA if their product is intended to treat serious or life-threatening diseases and there is preliminary clinical evidence that it can address unmet medical needs.
Thus far, only three companies (Abeona Therapeutics, Athersys, and Rocket Pharmaceuticals) have received two RMAT designations from the U.S. FDA.

What is an RMAT?
RMAT is an acronym that stands for “Regenerative Medicine Advanced Therapy.” The designation was introduced in December 2016 as part of the 21st Century Cures Act.
An RMAT submission request must be made in conjunction with an Investigational New Drug application (IND), either concurrently or as an amendment to an existing IND.
Products eligible for an RMAT designation include:
- Cell therapies
- Gene therapies
- Therapeutic tissue engineering products
- Human cell and tissue products
- Combination products using such therapies or products
RMAT Definition
By definition, an RMAT is an award from the U.S. FDA that allows for faster, more streamlined approvals of regenerative medicine products within the United States, such as cell and gene therapies, tissue engineering products, and combination products. RMAT designations make innovative products eligible for quicker development and review of a marketing application.
An RMAT designation is similar to the breakthrough therapy designation that is available to drugs.
Benefits of an RMAT include increased opportunities to meet with FDA officials, as well as early meetings to discuss potential surrogate or intermediate endpoints.
21st Century Cures Act
The 21st Century Cures Act was passed by the 114th U.S. Congress in December 2016. The act authorize $6.3 billion in funding, most of which is allocated for the National Institutes of Health (NIH).
The bill, passed by both houses of Congress and signed into law by President Obama, puts the U.S. on the same playing field as other countries that support accelerated of innovative medicines. Other regions that have accelerated pathways include Japan, South Korea, and the EU. The bill encourages late-stage development in regenerative medicine, recognizing the field’s potential to address severe unmet medical needs.
Congress included several provisions related to cell and gene therapies in the 21st Century Cures Act, the most important of which is the RMAT designation.
RMAT Reviews by The FDA
For more detail, the following is from the U.S. FDA:
As described in Section 3033 of the 21st Century Cures Act, a drug is eligible for regenerative medicine advanced therapy (RMAT) designation if:
- The drug is a regenerative medicine therapy, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product using such therapies or products, except for those regulated solely under Section 361 of the Public Health Service Act and part 1271 of Title 21, Code of Federal Regulations;
- The drug is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and
- Preliminary clinical evidence indicates that the drug has the potential to address unmet medical needs for such disease or condition.

Cade this is impressive and useful information for the industry and those scientist who want to bring products to market legally.
Thank you.
Don’t know if they have or will, but Biostage fits this perfectly.
