The U.S. Food and Drug Administration granted 23andMe authorization to offer 10 genetic health risk reports including late-onset Alzheimer’s disease, Parkinson’s disease, celiac disease and a condition associated with harmful blood clots.
For several years, 23andMe has worked on demonstrating that its reports are easy to understand and analytically valid in order to meet FDA requirements. The decision this week provides a clear pathway for submitting additional genetic health risk reports for the FDA’s consideration.
“The FDA has embraced innovation and has empowered people by authorizing direct access to this information,” said 23andMe co-founder and CEO Anne Wojcicki. “It is a significant step forward for 23andMe and for the adoption of personal genetics.”
Authorized Genetic Health Risk Reports
Alpha-1 Antitrypsin Deficiency (AATD) Celiac Disease Early-Onset Primary Dystonia (DYT1/TOR1A-Related) Factor XI Deficiency G6PD Deficiency Gaucher Disease Hereditary Hemochromatosis Hereditary Thrombophilia Late-Onset Alzheimer’s Disease Parkinson’s Disease |
The decision on these reports came through the FDA’s de novo classification process. This is a regulatory pathway for first-of-its-kind medical devices that the FDA considers low to moderate risk, but have special controls to ensure safety, effectiveness and accuracy. For this authorization, 23andMe conducted extensive validation studies for accuracy and user comprehension that met FDA standards.
23andMe is now the only company authorized by the FDA to provide personal genetic health risk reports without a prescription. These reports provide individuals with information about genetic variants that could increase their personal risk for certain diseases.
The company will release its first set of new genetic health risk reports including late-onset Alzheimer’s disease, Parkinson’s disease, hereditary thrombophilia, alpha-1 antitrypsin deficiency, and a new carrier status report for Gaucher’s disease in April, with additional reports to follow. New 23andMe Health + Ancestry customers in the U.S. will have access to these reports. Current 23andMe customers will be notified directly on their eligibility for receiving the new genetic health risk reports.
In addition to the authorization, the FDA indicated it will create something called a “Class II exemption” for 23andMe’s substantially equivalent reports. This opens a pathway for 23andMe to release additional genetic health risk reports that meet this “substantially equivalent” designation.
Prior to this most recent authorization, the FDA authorized 23andMe in February of 2015 to market the first direct-to-consumer genetic test for Bloom Syndrome under the de novo pathway. This in turn enabled the company to bring back more than 35 carrier status reports which identify inherited recessive variants.
Genetic health risk reports, by contrast, convey personal health risk, necessitating a separate FDA review classification pathway. In its decision this week, the FDA specifically authorized 23andMe to market genetic health risk reports through the de novo classification pathway including: alpha-1 antitrypsin deficiency (AATD), celiac disease, G6PD deficiency, hereditary thrombophilia which is associated with blood clotting, early-onset primary dystonia, hereditary hemochromatosis, which is associated with iron overload in the blood, among other reports.
Answers to some of your questions:
Does this mean 23andMe will bring back all the health reports they previously offered to customers?
We will continue to work with the FDA to offer additional genetic health risk reports to our customers — we can’t speculate on specific new reports or the timing of those reports.
What is a ‘genetic health risk’ report?
A genetic health risk report offers customers the opportunity to see whether they have genetic variants that affect their chances of developing certain health conditions. Some variants can add to a person’s risk, some can lower their risk and others have no effect. Not everyone with a risk variant will develop the health condition and not having a genetic variant does not eliminate the risk of the health condition.
What does it mean to be granted a de novo authorization?
The Food and Drug Administration Modernization Act of 1997 (FDAMA) added the de novo classification option, which provides an alternate pathway to classify novel devices of low to moderate risk. The de novo process is used by the FDA to grant marketing authorization for devices that are new and unlike any other on the market. In addition de novo marketing authorization means that 23andMe met the FDA’s premarket requirements to demonstrate the following: accuracy, validity and user comprehension.
When will you be getting clearance for the other health reports?
We do not know, but we will continue to work in close collaboration with the FDA, on additional submissions for other genetic health risk reports.
Will this speed up the process for authorization of other reports?
23andMe has now established a regulatory pathway with FDA and designed and validated its products to meet those standards.
