Thank you, Dave. Third quarter product sales increased 4% year-over-year. Volumes increased 8% globally, and we had record quarterly sales for several of our key products, including EVENITY, KYPROLIS, XGEVA and Nplate. Our ex U.S. business grew 19% with volume growth of 25% year-over-year. We continue to execute our volume-driven growth strategy and see gradual recovery in our business from the impact of the pandemic. During the early part of Q3, we saw volatility in patient care dynamics due to a surge in COVID-19. As we progressed through the quarter, we saw improvement in patient visits and diagnoses. Total customer activity improved during Q3. However, face-to-face customer interactions remain below 2019 levels. Now let me review some product details, beginning with our general medicine portfolio, which includes Prolia, EVENITY, Repatha, and Aimovig. Overall revenue for our general medicine portfolio grew 22% year-over-year with 24% volume growth. In bone health, Prolia sales grew 15% year-over-year, driven by double-digit volume growth. In the third quarter, new and repeat patient demand continued to improve as osteoporosis diagnosis rates reached over 90% of pre-COVID levels. EVENITY, which complements Prolia in our bone portfolio, had record sales of $149 million for the third quarter, driven by strong volume growth.
Given the severe impact of fractures on the lives of postmenopausal women, EVENITY provides an excellent therapy to build bone first. Moving to Repatha, which remains the global leader in the PCSK9 class. Repatha sales increased 33% year-over-year, driven by 42% volume growth. In the U.S., we saw 64% year-over-year volume growth. This was partially offset by lower net selling price stemming from an increase in the number of Medicare Part D patients receiving Repatha and who entered the doughnut hole. Outside the U.S., volumes grew 24% year-over-year. We remain confident in our ability to grow Repatha globally to address the significant unmet medical need in treating high-risk cardiovascular patients. Moving to our inflammation portfolio, Otezla sales increased 13% year-over-year with 7% volume growth. Since its launch, Otezla has been used by over 750,000 patients globally. And in the U.S., it is the leader in bio-naive psoriasis patient share. Otezla has 92% commercial payer coverage and is an affordable, safe and efficacious option for psoriasis and psoriatic arthritis patients. We are now preparing for the anticipated U.S. approval of the mild-to-moderate psoriasis indication in the fourth quarter when we will have the opportunity for the first time to promote the use of Otezla in this patient population.
Enbrel sales decreased 3% year-over-year, driven by a 2% decline in volume. This is the second straight quarter of slowing volume declines, thanks to Enbrel's long track record of efficacy and safety. Together with our partner, AstraZeneca, we're preparing for the launch of tezepelumab in the U.S. with an expected PDUFA date in early Q1 2022. Our sales force is fully staffed, trained and has been deployed to provide disease state education. We are actively engaging with payers to ensure access to patients for this breakthrough medicine. We look forward to bringing tezepelumab to the 2.5 million people around the world who live with severe uncontrolled asthma. Moving to the hematology and oncology business. Sales of our six innovative products and our MVASI and KANJINTI biosimilars collectively totaled $1.8 billion in the quarter, growing 12% year-over-year. Several brands had record sales in the quarter, including XGEVA, KYPROLIS, Nplate, and BLINCYTO. Neulasta Onpro maintained 50% volume share in the quarter and continues to be the preferred choice for physicians and patients. The most recent published average selling price for Neulasta in the U.S. declined 38% year-over-year and 10% quarter-over-quarter. Going forward, we expect increased competition to result in continued net price and volume erosion.
. Our launch of LUMAKRAS is off to a strong start with revenues of $36 million in Q3 and cumulative sales of $45 million through the end of the third quarter. LUMAKRAS has been prescribed by over 500 oncologists in both academic and community settings. A majority of clinical laboratories have updated their testing reports to reflect KRAS G12C as an actionable mutation and approximately 75% of patients with non-small cell lung cancer are now being tested for the mutation at the time of diagnosis. Having been a part of several lung cancer launches in my career, I'm very pleased with the LUMAKRAS launch uptake in the U.S. Thanks to our broad payer access and the positive reaction from the oncology community. Outside the U.S., health authorities have also approved LUMAKRAS in Canada and LUMAKRAS in the U.K. Overall, I'm pleased with our results for the quarter, our record sales across a number of products and our increasing levels of customer activity. And with that, I'll turn it to Peter.
