Product Sales

Total product sales for the second quarter of 2017 were $7.0 billion compared to $7.7 billion for the same period in 2016. Product sales for the second quarter of 2017 were $5.0 billion in the United States, $1.4 billion in Europe and $665 million in other locations. Product sales for the second quarter of 2016 were $4.9 billion in the United States, $1.6 billion in Europe and $1.2 billion in other locations.

Antiviral Product Sales

Antiviral product sales, which include sales of our HIV, chronic hepatitis B (HBV) and chronic hepatitis C (HCV) products, were $6.4 billion for the second quarter of 2017 compared to $7.1 billion for the same period in 2016.

• HIV and HBV product sales were $3.6 billion compared to $3.1 billion for the same period in 2016. The increase was primarily due to the continued uptake of our tenofovir alafenamide (TAF) based products, Genvoya® (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir alafenamide 10 mg), Descovy® (emtricitabine 200 mg/tenofovir alafenamide 25 mg) and Odefsey® (emtricitabine 200 mg/rilpivirine 25 mg/tenofovir alafenamide 25 mg).
• HCV product sales, which consist of Harvoni® (ledipasvir 90 mg/sofosbuvir 400 mg), Sovaldi® (sofosbuvir 400 mg) and Epclusa® (sofosbuvir 400 mg/velpatasvir 100 mg), were $2.9 billion compared to $4.0 billion for the same period in 2016. The decline was due to lower sales of Harvoni and Sovaldi across all major markets, partially offset by sales of Epclusa, which was approved in the United States and Europe in June and July 2016, respectively.

Other Product Sales

Other product sales, which include Letairis® (ambrisentan), Ranexa® (ranolazine) and AmBisome® (amphotericin B liposome for injection), were $607 million for the second quarter of 2017 compared to $525 million for the same period in 2016.

Operating Expenses

  Three Months Ended   Six Months Ended June 30, June 30, (In millions) 2017   2016 2017   2016 Research and development expenses (R&D) $ 864 $ 1,484 $ 1,795 $ 2,749 Non-GAAP R&D expenses* $ 812 $ 1,040 $ 1,701 $ 1,809   Selling, general and administrative expenses (SG&A) $ 897 $ 890 $ 1,747 $ 1,575 Non-GAAP SG&A expenses* $ 827 $ 838 $ 1,634 $ 1,476  

* Non-GAAP R&D and SG&A expenses exclude acquisition-related, up-front collaboration, stock-based compensation and other expenses. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 7 and 8.

During the second quarter of 2017, compared to the same period in 2016:

• R&D expenses decreased primarily due to the 2016 impact of Gilead’s purchase of Nimbus Apollo, Inc. and a U.S. Food and Drug Administration (FDA) priority review voucher.
• Non-GAAP R&D expenses* decreased primarily due to the 2016 impact of Gilead’s purchase of an FDA priority review voucher.

Cash, Cash Equivalents and Marketable Securities

As of June 30, 2017, Gilead had $36.6 billion of cash, cash equivalents and marketable securities compared to $34.0 billion as of March 31, 2017.

Product and Pipeline Updates announced by Gilead during the Second Quarter of 2017 include:

Antiviral and Liver Diseases Programs

• Announced that the European Committee for the Medicinal Products for Human Use, the scientific committee of the European Medicines Agency, adopted a positive opinion on the marketing authorization application for VoseviTM, a once-daily, single-tablet regimen of sofosbuvir 400 mg, velpatasvir 100 mg and voxilaprevir 100 mg for the treatment of HCV-infected patients. On July 18, 2017, Vosevi was approved by FDA.
• Announced the submission of a new drug application (NDA) to FDA for an investigational, once-daily single-tablet regimen containing bictegravir (50 mg) (BIC), a novel investigational integrase strand transfer inhibitor, and emtricitabine/tenofovir alafenamide (200/25 mg) (FTC/TAF) for the treatment of HIV-1 infection in adults. BIC/FTC/TAF demonstrated high rates of virologic suppression and no treatment-emergent resistance through 48 weeks in Phase 3 clinical trials among treatment-naïve adult patients and among virologically suppressed adult patients who switched regimens. Additionally, Gilead submitted a marketing authorization application for BIC/FTC/TAF in the European Union during the second quarter of 2017.
• Presented data at the 52nd Annual Meeting of the European Association for the Study of the Liver: The International Liver Congress™ 2017 which included the announcement of:
  • Positive results from an open-label, proof-of-concept study evaluating GS-0976, an investigational inhibitor of acetyl-CoA carboxylase, in patients with nonalcoholic steatohepatitis. The data, from ten patients treated with GS-0976 20 mg taken orally once daily for 12 weeks, indicated that treatment was associated with statistically significant improvements in liver fat content and noninvasive markers of fibrosis, via inhibition of hepatic de novo lipogenesis.
  • Positive results from two Phase 2 studies evaluating Harvoni tablets in HCV-infected patient populations not previously studied in dedicated clinical trials with direct-acting antiviral therapies. The studies demonstrated HCV cure rates of 99 percent in children aged 6 to 11 years, and 100 percent in adult patients co-infected with HCV and HBV.
  • Positive 96-week results from two ongoing Phase 3 studies evaluating the safety and efficacy of daily Vemlidy® (TAF 25mg) in immune active patients and in patients switching from Gilead’s Viread (tenofovir disoproxil fumarate, TDF 300 mg). Vemlidy is a once-daily treatment approved for adults with HBV infection with compensated liver disease.
• Announced that FDA approved supplemental indications for Harvoni tablets and Sovaldi tablets for the treatment of HCV infection in adolescents without cirrhosis or with compensated cirrhosis, 12 years of age and older, or weighing at least 35kg. Harvoni was approved for pediatric patients with genotype 1, 4, 5 or 6 HCV infection. Sovaldi was approved for pediatric patients with genotype 2 or 3 HCV infection, in combination with ribavirin.

Forward-looking Statements

Statements included in this press release that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Gilead cautions readers that forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially. These risks and uncertainties include: Gilead’s ability to achieve its anticipated full year 2017 financial results; Gilead’s ability to sustain growth in revenues for its antiviral and other programs; the risk that estimates of patients with HCV or anticipated patient demand may not be accurate; the risk that private and public payers may be reluctant to provide, or continue to provide, coverage or reimbursement for new products, including Vosevi, Vemlidy, Epclusa, Descovy, Odefsey and Genvoya; the potential for increased pricing pressure globally and contracting pressure as well as decreased volume and market share from additional competitive HCV launches; a larger than anticipated shift in payer mix to more highly discounted payer segments and geographic regions and decreases in treatment duration; availability of funding for state AIDS Drug Assistance Programs (ADAPs) and Veterans Administration (VA); continued fluctuations in ADAP and VA purchases driven by federal and state grant cycles which may not mirror patient demand and may cause fluctuations in Gilead’s earnings; market share and price erosion caused by the introduction of generic versions of Viread and Truvada outside the United States; potential amendments to the Affordable Care Act or other government action that could have the effect of lowering prices or reducing the number of insured patients; the possibility of unfavorable results from clinical trials involving investigational compounds; the levels of inventory held by wholesalers and retailers which may cause fluctuations in Gilead’s earnings; Gilead’s ability to submit new drug applications and receive regulatory approval for new product candidates in the timelines currently anticipated or at all, including for Vosevi and BIC/FTC/TAF; Gilead’s ability to successfully develop its oncology, inflammation, cardiovascular and respiratory programs; safety and efficacy data from clinical studies may not warrant further development of Gilead’s product candidates, including GS-0976; Gilead’s ability to pay dividends or complete its share repurchase program due to changes in its stock price, corporate or other market conditions; fluctuations in the foreign exchange rate of the U.S. dollar that may cause an unfavorable foreign currency exchange impact on Gilead’s future revenues and pre-tax earnings; and other risks identified from time to time in Gilead’s reports filed with the U.S. Securities and Exchange Commission (SEC).
