INHALED PRESCRIPTION TO QUIT SMOKING — Roughly a year after Mitch Zeller retired as the head of the FDA’s Center for Tobacco Products in 2022, he joined the advisory board of Qnovia, a young pharma company focused on developing inhaled therapies, last month. The first order of business for the well-respected former regulator? Advising the company on getting the first inhaled smoking cessation device approved by the FDA as a drug product. “Here’s the reality: We’ve plateaued,” Zeller told Prescription Pulse. “We’re doing a great job at preventing kids from becoming new smokers, but when it comes to existing adult smokers, almost all of whom are addicted, we need something new. We need something innovative.” Unlike nicotine gum or patches, Qnovia’s product, dubbed RespiRx, allows users to inhale nicotine, but it is not an e-cigarette, explained Brian Quigley, Qnovia’s CEO and former head of Altria’s smokeless tobacco division. Roughly 40 million smokers will try — and fail — to quit this year, according to the CDC. Quigley blames a lack of effective smoking-cessation tools. While neither Zeller nor Quigley described their product as a game-changer, it could well be if it’s successful. RespiRx weans users off nicotine over time by having a preset number of nicotine doses available throughout the day. E-cigarettes appeal to smokers looking to quit because they provide the same hit of the addictive stimulant nicotine but without harmful tobacco smoke. Smokers often prefer vapes to nicotine replacement patches or gum because they provide immediate nicotine delivery, similar to the way cigarettes do. But most smokers who switch to e-cigarettes never truly overcome their nicotine addiction — they just use a new, albeit less harmful, product. Vapes are also regulated as tobacco products — which must only prove to the FDA that they are not harmful to adults and not likely to draw in kids. Qnovia will seek approval as a medical product regulated by the agency’s Center for Drug Evaluation and Research. The company must demonstrate RespiRx is safe and effective through rigorous clinical testing. Qnovia expects to file an investigational new drug application for RespiRx this year, which would allow the company to begin clinical trials. Qnovia aims to complete the trials by 2025 when it will file for approval. The FDA’s approval process could then take another 10 months unless the agency reviews RespiRx on an accelerated pathway. If approved, it would be Qnovia’s first product to hit the market. IT'S TUESDAY. WELCOME TO PRESCRIPTION PULSE. Attending the World Vaccine Congress this week in Washington?
