Less than a month after would-be competitor DBV Technologies SA suffered a regulatory setback with its peanut allergy patch candidate, Aimmune Therapeutics Inc. – which at the start of the year gained FDA clearance for Palforzia in the same space – is undergoing an all-cash takeover valued at $2.6 billion by Nestle SA unit Nestle Health Science SA.

Adopting a new strategy in food allergies and others, South San Francisco-based Iggenix Inc. launched with a $10 million series A round to fund work that CEO Bruce Hironaka told BioWorld puts the company “at the front of the wave.” Companies in the allergy space generally “have not taken full advantages of the developments that we’ve seen in the biotech industry over the last 20 or 30 years,” he said.

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.

Aimmune Therapeutics Inc. wasted no time moving ahead after last week’s FDA approval of Palforzia for peanut allergy as the Brisbane, Calif.-based company obtained an exclusive worldwide license to develop and commercialize Xencor Inc.’s humanized monoclonal antibody, XmAb-7195, for treating allergic asthma.
