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 U.S. FDA expanded the indications for Stryker Corp.’s Neuroform Atlas stent system to include use in the posterior circulation or back of the brain, making the device the only adjunctive stent approved for aneurysms in this challenging location.
