The FDA’s Arthritis Advisory Committee panelists groped through cloudy data while complaining about the design of the phase III trial for Chemocentryx Inc.’s avacopan, and after going overtime ended up without consensus. Briefing documents ahead of the meeting darkened what had been a fairly bright picture for the complement C5a receptor inhibitor for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, but Wall Street held out hope. Wainwright analyst Edward White opined in a May 5 report that the adcom’s outcome “could still be positive,” and a May 4 dispatch from Canaccord Genuity’s Michelle Gilson said the briefing docs “miss[ed] the big picture.”

The FDA’s May 4 webinar on patient data generated over the course of the product life cycle covered a number of topics, including the use of social media as a source of real-world evidence (RWE). The FDA’s Anne Hammer said, however, that while social media engagement has exploded over the past couple of decades, issues such as data duplication and verifiability will have to be resolved before patient engagement via social media can be relied upon as a source of RWE for regulatory purposes.

Molli Surgical Inc. has won the FDA’s nod for its wire-free localization technology for breast cancer surgery. The company said the Molli system helps radiologists tag cancerous lesions quickly and precisely, facilitating surgical excision and eliminating a source of anxiety associated with breast tumor removal.

The negotiations for the next device user fee agreement are well underway, and there are signs that the FDA is looking for a significant boost in user fees from device makers. However, Rep. Anna Eshoo (D-Calif.) told members of the MDMA that no member of Congress should believe that user fees relieve Congress of its responsibility “for funding the agency in a robust way.”

The FDA slapped Leo Pharma A/S’ BLA for IL-13 inhibitor tralokinumab with a complete response letter (CRL), making it the latest atopic dermatitis candidate to hit a regulatory setback in the U.S., following delays for three oral JAK inhibitor drugs earlier this month.

The FDA’s Oncologic Drugs Advisory Committee voted 6-2 April 29 to recommend withdrawing accelerated approval for Merck & Co. Inc.’s Keytruda (pembrolizumab) as a third-line treatment for a subgroup of patients with recurrent locally advanced or metastatic gastric or gastroesophageal junction cancer. The vote was based on FDA assurances that, if it withdrew the approval, it would work with Merck to delay the withdrawal or set up an access program to ensure the estimated 1,000 patients who are beyond first-line treatment could still get Keytruda.

Atricure Inc. has received the green light from the FDA for its Epi-Sense guided coagulation system with Visitrax technology to treat patients diagnosed with long-standing, persistent atrial fibrillation (AF). The device was previously cleared via a 510(k) for the coagulation of cardiac tissue, and is already available in the U.S. The FDA approval represents the first and only minimally invasive ablation therapy for the more than 3 million Americans with longstanding AF.
