Top-Selling Drugs of Gilead

Identification of Top-Selling Drugs
The top-selling drugs of Gilead are primarily concentrated in its HIV and antiviral divisions, which have historically driven much of the company’s revenue. Detailed analyses of Gilead’s product sales and its market messaging have identified several blockbuster therapies:

• Biktarvy:
  - Widely recognized as the flagship therapy for HIV, Biktarvy consistently tops Gilead’s sales charts. It is a once-daily, oral antiretroviral regimen that has achieved robust market penetration globally, with nearly one million patients treated worldwide during 2022 alone. Biktarvy leads the charge for Gilead’s HIV franchise not only through high revenue but also via continued strong demand and market share gains in regions like the United States and Europe.

• Veklury (Remdesivir):
  - Initially developed for COVID-19 treatment, Veklury became synonymous with Gilead’s contribution to the global pandemic response. It received significant attention following its FDA emergency use approval and full approval later, generating billions in sales during the height of the outbreak. However, as COVID-19 hospitalizations declined, its sales began to drop. Despite that, Veklury represents one of the top-selling assets in the company’s portfolio during the pandemic years.

• Descovy and Genvoya:
  - Alongside Biktarvy, Gilead’s other combination therapies such as Descovy and Genvoya have also been major revenue contributors. These regimens address HIV treatment from different patient perspectives and have benefited from favorable pricing dynamics and a broad patient base, although their individual sales figures can vary depending on the region and market conditions.

• Emerging Oncology Products (Yescarta, Tecartus, Trodelvy):
  - While not traditionally categorized alongside the longstanding antivirals, newer oncology therapies such as Yescarta and Tecartus have seen significant sales growth. In particular, Trodelvy, approved for metastatic triple-negative breast cancer, has delivered fast-growing revenues and emerged as a promising contributor to Gilead’s oncology portfolio. These drugs, though relatively new compared to the HIV blockbusters, have captured investor attention and are important parts of the company’s diversification strategy.

Collectively, the evidence points to Gilead’s top-selling products being dominated by Biktarvy, which continues to drive the HIV segment, along with COVID-19 antiviral Veklury that played a pivotal role during the pandemic, and other combination therapies like Descovy and Genvoya that support the health of millions of patients worldwide.

Sales Data and Trends
The sales performance of these drugs is measured across several key reporting periods and geographies, reflecting both growth trends and market saturation dynamics:

• Biktarvy:
  - Biktarvy stands out as the powerhouse in Gilead’s portfolio. During 2022, its sales were instrumental in driving the overall growth of the HIV segment. For instance, one report noted that nearly one million patients were treated with Biktarvy during that year, with the drug gaining consistent market share quarter after quarter.
  - In quarterly reports, Biktarvy’s sales have reflected double-digit growth; one report mentioned an increase of about 12% year-over-year in one quarter, leading to revenues at or exceeding $3 billion in some markets (such as the U.S.).

• Veklury (Remdesivir):
  - At its peak as a pandemic treatment, Veklury generated annual sales in the vicinity of $7 billion. However, due to a decline in COVID-19-related hospitalizations and overall pandemic fatigue, recent quarterly reports indicated substantial percentage declines in Veklury sales (for example, a drop by 31% in one quarter compared to analysts’ forecasts).
  - Despite this, Veklury remains important, as its revenue reflects changing dynamics in public health, and the figures are still significant relative to other drugs in the portfolio.

• Descovy and Genvoya:
  - These combination therapies have also experienced robust sales. Descovy, for example, has seen year-over-year increases of around 20%, driven by both higher demand and favorable channel pricing dynamics.
  - Genvoya, while experiencing some regional variations, has contributed steady revenue streams; however, some quarters have recorded declines in its sales figures relative to previous periods, indicating competitive pressures and market adjusting factors.

• Oncology Products (Yescarta, Tecartus, Trodelvy):
  - Although the HIV franchise continues to dominate, Gilead’s oncology products are growing at an impressive rate. For example, one detailed report described that the cell therapy segment—which includes Yescarta and Tecartus—grew by nearly 80% in a quarter, while Trodelvy experienced increases in the 50–60% range, reflecting strong market uptake for cancer indications.
  - These drugs are being closely watched as potential significant contributors to future revenue diversification, especially as the traditional antiviral revenue faces pressures from generic competition and market saturation.

In summary, while past performance of top-selling drugs like Biktarvy, Veklury, Descovy, and Genvoya has provided a strong revenue foundation, the data show nuanced trends. Sales figures for HIV therapies remain robust even amid increased competition, whereas COVID-19 related sales of Veklury have declined, and emerging oncology drugs are showing rapid growth aimed at offsetting maturities in the antivirals segment.

Market Impact and Analysis

Market Share and Competitors
Gilead’s dominance in the global HIV market has long placed it ahead of many competitors within the antiviral segment. The company’s market share in HIV therapeutics is notable—estimates indicate that its flagship drug, Biktarvy, holds a very substantial share of the market, contributing to over 50% combined sales in some regions.
