The additional challenges to launching new drugs that emerged since COVID-19 upended the biopharma industry, and life as we knew it, will continue into 2021, according to the annual list of trends released December 21 by Seqens CDMO North America (formerly PCI Synthesis, a contract development and manufacturing organization focused on producing new chemical entities (NCEs), active pharmaceutical ingredients (APIs), and other specialty chemical products.

Those challenges, according to Seqens CDMO NA, include supply chain issues that require companies to find alternative sources for raw materials; and the potential for shortages of medicines due to biopharmas diverting raw materials and manufacturing capacity to producing COVID-19 drugs and vaccines. More than 300 such therapeutics are in development, according to GEN’s COVID-19 DRUG & VACCINE TRACKER.

And despite the demand by politicians across the political divide for lower prices, drug prices will likely rise, Seqens CDMO NA predicted. It offered reasons extending beyond possible drug shortages and the ongoing cost of developing new medicines, including the many layers of drug delivery partners that add costs without adding value.

“Companies and regulators need to make long-term systemic changes to ensure the U.S. and the world can be better positioned to handle potential disruption from a future pandemic,” Ed Price, founder of Seqens CDMO NA, said in a statement. “This will include finding new ways to protect supply chains and streamline processes to more easily work with regulators and get faster approvals while ensuring patient safety.”

Yet the challenging environment for drug development has not stopped companies from launching dozens of new treatments.  The FDA, for example, approved no fewer than 52 novel drug approvals during 2020  as of December 21—already surpassing the 48 approvals issued in 2019, though just under the 59 approvals granted in 2018.

Top 15 Best-Selling Drugs Launched in 2020

Below is GEN’s top 15 A-List of top-selling prescription drugs launched in 2020, based on sales data disclosed by the drugs’ developers through the first three quarters.

Top-selling drugs are ranked based on sales or revenue reported for the first through third quarters of 2020 by biopharma companies in press announcements, annual reports, investor materials, and/or conference calls. Each drug is listed by name, reported sales, sponsor(s), type, and diseases for which the treatment is indicated.

Ranking #20 through #16 in Q1-Q3 2020 were treatments that generated between CHF 7 million (about $7.9 million) and $11.875 million—Enspryng (satralizumab-mwge) and Evrysdi (risdiplam), both from Genentech, a Member of the Roche Group; Intra-Cellular Therapies’ Caplyta (lumateperone); GlaxoSmithKline’s Blenrep (belantamab mafodotin-blmf), and Incyte’s Pemazyre® (pemigatinib).

Nearly half (seven) of the top 15 drugs launched in 2020 as of deadline were indicated for various forms of cancer—with two of the therapeutics launched as treatments for gastrointestinal stromal tumors (GIST). Two top-selling newly launched drugs listed below are indicated for migraines (as was a third drug that generated too little in sales to make the list, Lundbeck’s Vyepti™ [eptinezumab-jjmr]), which made only DKK 42 million (about $6.9 million).

Another two top selling drugs were indicated for blood disorders. And as might be expected during the pandemic, another two of the top 15 best-selling newly launched drugs were indicated as treatments for COVID-19.

Not included on the list were drugs for which data was unavailable for any of several reasons: In some cases, a drug’s developer was privately held and did not disclose any sales information. In other cases, a publicly-traded developer of a newly-launched drug limited its sales disclosures to its top-selling therapeutics. Still in other cases, the launch of a drug came during the fourth quarter, with data to emerge only when the company reports fourth quarter results in 2021.
