In August 2020, it looked like DBV Technologies SA was in considerable trouble after the U.S. FDA served it with a rejection for its Viaskin Peanut allergy patch, raising concerns efficacy could be compromised because the product wasn’t sticking to the skin well. But could the Montrouge, France-based firm be making a comeback with the epicutaneous technology?
The matter of how adhesion of its Viaskin Peanut allergy patch relates to efficacy became a major problem for DBV Technologies SA, which drew a complete response letter (CRL) for the once-daily epicutaneous (EPIT) product. Shares of the Montrouge, France-based firm (NASDAQ:DBVT) closed Aug. 4 at $2.34, down $1.76, or 43%, in reaction to the CRL for the patch, designed to protect children ages 4 to 11. The FDA wants DBV to modify the patch, which means a new human-factor study; officials also are requiring clinical data for the modified patch.
DBV Technologies SA officials took pains to reassure investors that data wanted by the FDA with regard to the BLA for Viaskin Peanut allergy therapy are already in hand and need only be turned over to the agency, but that didn’t stop shares (NASDAQ:DBVT) from sliding 55.7%, or $2.93, to close March 17 at $2.33.
