On February 10, 2026, the U.S. Food and Drug Administration (FDA) convened a multi-session roundtable on Premarket Tobacco Applications (PMTAs) for electronic nicotine delivery systems (ENDS), bringing together senior agency officials and industry representatives to discuss scientific standards and regulatory expectations under the “Appropriate for the Protection of Public Health” (APPH) framework.
The discussions spanned product characterization, manufacturing controls, pharmacological assessment, studies of adult benefit, and toxicological review—offering rare public visibility into the agency’s current evaluation approach.
As of February 11, 2026 (Beijing Time), 2Firsts has published eight in-depth reports covering each panel session and key regulatory signals from the meeting. Together, these reports provide one of the most systematic and timely documentations of the event, examining scientific methodologies, review frameworks, and industry responses.
2Firsts will continue to follow developments related to FDA PMTA policy and review practice. Readers are invited to follow ongoing updates on the 2Firsts website and across our social media channels.

Panel I: Product Characterization
2FIRSTS | FDA Highlights Product Characterization as a Foundational Requirement in ENDS PMTA Reviews
During its ongoing PMTA roundtable, FDA emphasized that product characterization is a foundational element in the review of electronic nicotine delivery systems (ENDS). The agency underscored the need for complete product identifying information, validation and verification of test methods on the specific product type, and the appropriate use of tobacco product master files (TPMFs) to support complex or proprietary ingredients in PMTA submissions.

Panel II: Manufacturing Controls
2FIRSTS | FDA Outlines Manufacturing Requirements as Critical to ENDS PMTA Success
FDA officials said manufacturing consistency is a core prerequisite for ENDS PMTA reviews, not a procedural formality. During its February 10, 2026 roundtable, the agency outlined expectations for quality management systems, manufacturing documentation, nicotine control, stability studies, and risk mitigation, emphasizing that robust manufacturing evidence underpins determinations of whether products are appropriate for the protection of public health.

2FIRSTS | PMTA Manufacturing Panel Sees Small Firms Warn “Unknown Is Death” as FDA Defends Review Boundaries
During FDA’s Feb 10 PMTA roundtable (manufacturing controls panel), small ENDS manufacturers warned that uncertainty in manufacturing expectations creates existential financial risk. FDA officials reiterated review flexibility is constrained by statutory and scientific boundaries. The panel debated testing standards, documentation requirements, open-system responsibility, supply chain changes, and software updates—highlighting unresolved PMTA challenges for small manufacturers.

Panel III: Pharmacological Profile
2FIRSTS | Small ENDS Manufacturers Press FDA on Abuse Liability Standards as Agency Defines Pharmacological Review Framework
At the third session of its PMTA roundtable, the FDA outlined its framework for assessing abuse liability in ENDS products, emphasizing the role of nicotine pharmacokinetics and product-specific data in APPH determinations. Small manufacturers questioned the high cost of clinical PK studies and the absence of defined numeric thresholds, while raising bridging strategies and PBPK modeling as potential alternatives.

Panel IV: Studies of Adult Benefit
2FIRSTS | FDA Says Flavored ENDS Must Show “Added Benefit” as Small Manufacturers Seek Clearer Switching Benchmarks
During the FDA PMTA roundtable session on “Studies of Adult Benefit,” officials said flavored ENDS must demonstrate “added benefit” over tobacco-flavored products under the APPH standard, including sustained complete switching evidence. Small manufacturers questioned switching benchmarks, study duration, and bridging expectations.

Panel V: Toxicological Profile
2FIRSTS | FDA Details Carcinogenicity Tiering and ELCR Framework as Small Manufacturers Press for Predictability
During the “Toxicological Profile” session at FDA’s Feb 10 PMTA roundtable, officials outlined the carcinogenicity tiering system and Excess Lifetime Cancer Risk (ELCR) framework used in ENDS reviews under the APPH standard. Small manufacturers questioned database transparency, exposure assumptions, and the existence of clear compliance benchmarks. FDA reiterated toxicological risk is assessed case by case within a broader population-level determination.
