Kevin Sayer
Chairman, President And Chief Executive Officer at DexCom
Thank you, Sean, and thank you, everyone, for joining us. Today, we reported great results for our second quarter with 32% revenue growth for the quarter compared to the second quarter of 2020, as well as solid execution on our key strategic initiatives that we will discuss throughout the call today. The $143 million in absolute dollar revenue growth compared to the second quarter in 2020 represents the highest quarterly increase in DexCom's history.
We continue to believe that we are early in our story with the potential to drive a far greater impact on global health. Our growth performance is closely related to the progress we've made to advance access on our CGM systems for people with diabetes. And because there is often so much misinformation spread about access to DexCom's CGM in the field, while the cost of our products for people with diabetes.
Let me point out several key points that our investors, clinicians and current and potential customers should know. We've advanced pharmacy access in the U.S., where more than 70% of our commercial customers have a monthly out-of-pocket cost of less than $60 per month, and nearly 1/3 of our customers have 0 out-of-pocket costs for their G6 sensors. According to IQVIA, this is less than the comparable out-of-pocket cost for our nearest competitor. The latest research from diabetes market research firm, Seagrove Partners, confirms our conclusion.
With DexCom having the lowest customer co-pays of the three largest CGM suppliers in the U.S. for customers on intensive insulin therapy, we've significantly expanded coverage for people with intensively managed type two diabetes, with the overwhelming majority of these patients now having coverage for DexCom CGM in the U.S. We also continue to advocate for equitable access to our CGM supplies for populations that are often underserved.
As of July 2021, there are now 43 State Medicaid programs providing coverage for DexCom CGM, including a growing number of states providing access through their pharmacy channel for both type one and type two intensive users. We are building even more on those advocacy efforts in collaboration with several key nonprofit organizations that support the diabetes community. In June, we launched the global movement for time and range to broaden awareness of time and range and its benefits for people with diabetes and their health care providers.
And we hope that this collaboration effort will lead to future solutions for improved CGM access. Our teams have taken a leading role to drive the removal of administrative barriers that prevent people with diabetes from accessing the benefits of real-time CGM. Along these lines, we are pleased to see the update from CMS in the second quarter to remove the requirement of at least four daily finger sticks for Medicare customers. This will simplify the CGM onboarding process for both customers and clinicians.
We've also made solid progress internationally, building from our position of operational strength to advocate for broader reimbursement for G6. This initiative is moving forward according to plan with several geographies publicly announcing enhancements to their coverage of DexCom CGM in the second quarter. Despite these developments, a majority of people on mealtime insulin continue to manage their diabetes with finger sticks.
Even in the U.S., a leader in CGM adoption, we continue to believe that the type one market remains less than 50% penetrated and the type two intensive market is less than 25% penetrated. So there remains a great opportunity ahead of us, even in the markets that we currently serve. At the same time, we are generating a growing evidence base for the use of DexCom CGM. And at the ATTD and ADA industry conferences in June, we presented exciting research affirming the benefits of our product platform, including the ALERTT1 trial.
This randomized controlled trial was simultaneously published in the Lancet, showing superior health outcomes associated with the use of DexCom CGM relative to our nearest competitor, Flash Glucose Monitor. These conferences also featured several presentations on the use of CGM for people of type two diabetes, including those not using mealtime insulin as well as use in women who are pregnant used in the hospital setting and even conclusions applicable to health and wellness using CGM data.
Perhaps the most significant of these presentations was the long-awaited readout of our MOBILE trial, which was also published in the Journal of the American Medical Association. MOBILE is another rigorous randomized controlled trial assessing the value of DexCom CGM compared to the current standard of care, finger sticks, for people of type two diabetes treated with basal insulin. Importantly, the study looked at a diverse user base representative of the U.S. population, and it assess these people in a primary care clinical environments where they are traditionally served. So what did we see?
We saw clinically significant A1c reductions for users of our DexCom CGM systems. And perhaps even more telling, we saw a 16% time and range increase for the CGM cohort, which is four additional hours per day spent in the target glucose range. These were results produced with DexCom CGM and DexCom software. We designed the trial with the goal of changing the standard of care for these basal insulin users, a group that we believe includes between three million and four million people in the U.S. alone.
With these results, we feel that MOBILE and DexCom have the potential to do just that, and our teams look forward to driving better awareness and access based on the study outcomes and the JAMA publication. We also made great progress in the second quarter to advance the clinical and regulatory pathway for our next-generation G7 CGM system. At ATTD in June, we provided an update on the performance of G7 drawn from our recent clinical trials.
Based on the data shown, we expect that G7 will continue the excellent clinical and real world performance and reliability that we have established with our G6 brand. And it will do so with several factors that we believe will enhance our customer experience, including a fully disposable sensor and transmitter, a redesigned app experience and a market-leading 30-minute warmup period. Our G7 continues to progress according to our plans.
During the second quarter, we concluded our U.S. clinical trial that will support our iCGM filing and our teams have now shifted to processing the data and working toward preparing the regulatory filing. In addition, we've recently submitted G7 for CE Mark approval. As we previously discussed, we believe that this timing places us on track to begin the G7 launch by the end of 2021.
These are incredible achievements and advances from the quarter and a nice step forward to fulfill the promise presented by our CGM technology. And this is just the beginning. There are several additional areas of progress that Jereme and Quentin will discuss based on the great work of our teams in the past several months.
So with that said, let me turn it over to Jereme for a review of our second quarter financial performance. Jereme?
