Meet PMTA Submission Deadlines and Comply with 2-Year Stability Requirements

For vape, e-liquid, and ENDS companies looking to comply with the quickly approaching May 2020 Premarket Tobacco Application (PMTA) filing deadline, stability data must be included in their PMTA submission. If you’re familiar with the PMTA guidance, you may be wondering how 2 years of stability data can be generated in a few months’ time to include in a PMTA. In short, it can’t – but you can still submit the PMTA on-time and remain in compliance.

FDA Regulatory Submissions Can Include a Commitment to Complete a Stability Study

It’s common in the biopharma industry to provide regulatory submissions to FDA without complete stability information, and it’s no different with the PTMA. To meet the stability requirements of the PMTA, e-cigarette companies must complete both an accelerated and real-time stability study. A PMTA can be submitted to FDA with stability data that’s been generated up until the time of submission, with a commitment to complete the study. It’s then the responsibility of the company filing the PMTA to submit data for each time point the product is tested while on stability, once the testing for each pull is complete.

Accelerated & Real-Time Stability Studies Explained

Accelerated Stability Studies of ENDS Products

An accelerated stability study is just what it sounds like – a stability study that’s completed on an expedited time frame. E-liquid, e-juice, and vape flavor products are subjected to elevated temperature and humidity levels in a controlled environment. Typically, 1 month in accelerated conditions is equivalent to 4 months at ambient (room) temperature. Samples of the product are removed from stability chambers at regular intervals and tested for physical and chemical characteristics. The rate of chemical and physical degradation of the product provides data that allows scientists to calculate the degradation and expiry at ambient temperature. However, regulatory submissions also require real-time stability data to ensure that projected expiry and degradation rates are accurate.

Real-Time Stability Studies of E-Liquid, E-Cigarette & Vape Products

Real time stability studies are conducted in real-time. For a 2 year study, like the one required for PMTA submissions, ENDS, e-cigarette, and e-juice products must remain in a controlled environment with consistent ambient temperature and humidity levels for a 2 year period. At regular intervals (also known as time points or pulls), samples of the product are tested for physical and chemical characteristics, per an established protocol. The real-time stability study is completed concurrently with the accelerated stability study, and FDA requires the results of the real-time stability study be submitted to confirm product expiration and shelf life.
