How did dupixent's 2020 sales compare to 2019?

What were Dupixent (dupilumab) 2019 vs. 2020 sales?

From the information provided, I don’t have the actual Dupixent 2019 or 2020 sales figures needed to make the comparison.

If you share the sales numbers (or the specific report/table you’re using), I can calculate the year-over-year change (absolute and percent) and summarize the result.

Where could the 2019 and 2020 sales figures be coming from?

Dupixent sales are typically reported in company financials (by year) or in third-party market/indication summaries. If you point me to the source document or link, I can extract the 2019 and 2020 totals and compare them directly.

If you want, I can compute the exact comparison once you provide the numbers

To compare 2020 vs. 2019, the key outputs are:
- Difference = Sales(2020) − Sales(2019)
- Percent change = [Sales(2020) − Sales(2019)] / Sales(2019) × 100

Send the two sales totals (2019 and 2020), and I’ll produce the comparison in a clean, single paragraph.
