Most Important FDA Novel Drug Approvals of 2021, So Far

FDA novel drug approvals in 2021 have so far included drugs treating certain cancers, Alzheimer’s disease, and Multiple Sclerosis.

The novel FDA drug approval process allows researchers to uncover the appropriate dosage for both children and adults, determine the best route of administration, and test for any drug interactions. And so far in 2021, the FDA has issued 33 approvals under that process.
An FDA approval means that the drug’s safety and efficacy elicited benefits that outweighed known and potential risks for the intended population.

In the following article, PharmaNewsIntelligence breaks down the top 33 most important novel drug approval of 2021 so far. 

FDA Greenlights Biogen’s AZ Drug, Aduhelm

In June, FDA officially approved Aduhelm, Biogen’s Alzheimer’s disease drug. This approval marked the first Alzheimer’s drug approval in nearly 20 years and the first to address cognitive decline in those with the illness.
