In the ever-evolving landscape of the tobacco industry, challenges emerge in unexpected forms. Our latest endeavor revolves around a client who has been issued a deficiency letter by the FDA, specifying the necessary actions for additional testing. This situation presents a crucial juncture for our client, as failure to respond within the prescribed timeframe could potentially force them to withdraw their products from the market or, worse, jeopardize their chances of securing a coveted Marketing Grant Order (MGO).

However, within this challenge lies the opportunity for us to leverage our expertise, experience, and resources to assist our client in not only meeting but exceeding the FDA’s expectations. By navigating this regulatory hurdle effectively, we can ensure our clients’ products remain on the market and pave the way for future success in this highly regulated industry.


When the client received a deficiency letter from the FDA, the clock started ticking. They had only 90 days to respond with compelling evidence, including additional testing results. This tight timeframe added to the urgency and complexity of the situation.

Addressing the deficiency letter was not a solo endeavor. It required a cohesive effort from multiple fronts, bringing together regulatory affairs managers, project managers, and senior scientists. Their combined expertise was instrumental in navigating the intricate web of FDA regulations.


The foundation of this endeavor was the FDA’s Premarket Tobacco Applications (PMTA) submission regulations. Understanding and adhering to these regulations were pivotal in crafting a successful response.

Recognizing the critical nature of deficiency letter responses, these requests received top priority. Speed was of the essence to ensure compliance within the stipulated timeframe. This prioritization demonstrated a commitment to meeting FDA requirements promptly.

In the end, the client found a reliable ally in McKinney. Our expertise and commitment to providing legally defensible data ensured that deficiency testing requests were analyzed as quickly as possible. This partnership gave the client the peace of mind that they needed during this challenging process.

This case study exemplifies the intricacies between the tobacco industry and FDA regulations. It highlights the importance of timely, collaborative, and expert-driven responses to deficiency letters to maintain compliance and market presence. McKinney’s role in this success story underscores the value of partnering with trusted professionals in navigating the complex world of FDA requirements.
