Merck Could Get Help From Its Second-Tier Drugs
Summary:
- Top products including Keytruda and Gardasil face U.S. patent cliff in 2028 and need backup.
- Future blockbuster Reblozyl notched a formulary win.
- WELIREG, Prevymis and Verquvo are well placed among top U.S. insurers and Prevymis could secure label expansions.
Merck (NYSE:MRK), a large (~$275 billion market cap) biopharmaceutical company, announced its financial results for the fourth quarter of 2022 on February 2. The company highlighted full year 22% sales growth, which came courtesy of top earners Keytruda and Gardasil; the duo generated $27.8 billion and 47% of the company’s total annual revenues (Table 1). While EPS and revenues beat Wall Street estimates, the outlook for 2023 was less upbeat, leading to several downward revisions and a D- from the Quant System. This was expected, courtesy of erstwhile #3 product Lagevrio ($5.7 billion) anticipated to wind down in this year to $1 billion along with the Covid-19 threat. Sans the antiviral, 2022’s growth was only 12%, lower than 2021’s 15%. Yet the mixed earnings report was followed by a 5% rally as investors turned defensive as inflation fears mount and there is no end in sight for the year-long Russia-Ukraine war. Whether such gains are sustainable in the short-to-middle term is questionable.

Everyone who follows Merck is aware that the oncology behemoth Keytruda and vaccine stalwart Gardasil face loss of exclusivity in 2028 (along with Lymparza and Zerbaxa). Longs should hope for continued growth from the rest of the product line, and possibly some key acquisitions, to make up for the huge potential shortfall. Meanwhile, since few patients can afford to pay for these brands out of pocket, formulary placement is critical for greater accessibility, especially for products recently launched in the past few years.
Coverage for 5 select products was explored at the 15 largest health insurance companies in the U.S. overall. Combined, these payors control 59% market share, with 38 million covered lives as of 2021. Vaccines are readily available, while LAGEVRIO is distributed by the U.S. Government; these are excluded from the search. Reblozyl, a global collaboration with Bristol Myers Squibb (BMY) from which Merck receives a 20%-24% royalty based on sales levels; Verquvo, which is Adempas repurposed for heart failure; and Zerbaxa, reintroduced in Q4 2021 after being recalled in 2020, are included. The most common plan was examined when possible and are specified in Table 2. If the insurer offered non-Medicare prescription drug plans (“PDP”) in a state Marketplace (Obamacare), the most populous state was chosen (California > Texas > Florida). Humana (HUM) doesn’t do Exchanges, so their Medicaid plan and that of Blue Cross and Blue Shield of Texas are the only ones in the survey.
How to read Table 2:
Tier # Higher Tiers have higher cost share. Drugs in Tier 4 or higher (in 5+-Tier plans) are non-preferred brands and may also include drugs recently approved by the FDA or specialty drugs and may need special handling.
Sp Specialty drugs are used to treat difficult, long-term conditions and may need to get filled through a specialty pharmacy.
PA Prior authorization is the process of obtaining approval of benefits before certain prescriptions may be filled.
NF A non-formulary drug is not included on a plan’s Drug List. Exception processes such as PA or Step Therapy could be available to request coverage for a NF drug.
x Not Covered drugs are specifically excluded from coverage by the terms of the plan. Patients likely won’t get any reimbursement will have to pay out-of-pocket for these drugs.

WELIREG, Prevymis and Verquvo all have excellent coverage, the latter likely owing to insurers’ familiarity with Adempas. In January’s BMY article, it was noted that Reblozyl (a projected $4 billion earner) would have a smoother path to blockbuster status if coverage extended beyond 2 lists. Even the hospital-based antibiotic Zerbexa was on more. Fortunately for Merck, the anemia drug secured placement this month on #9 Highmark’s commercial and Medicare plans, although patients may have higher copays due to the non-formulary/specialty tier.
To conclude, none of these secondary products are currently bringing in more than $200 million annually in the U.S., and thus won’t budge the Guidance. However, these drugs are positioned to deliver greater sales once they are approved for more indications. First up for review by the FDA is the cytomegalovirus prophylactic pill Prevymis (also available as injection); the Agency will decide on the first of two supplemental new drug applications (“sNDAs”) on June 5, for use in high-risk adult kidney transplant recipients. The second sNDA aims to extend Prevymis’ authorized use in adults from 100 days to 200 days after receiving an allogeneic hematopoietic stem cell transplant, thereby doubling revenue. Until then, there are probably better choices among Big Pharma (e.g., BMY) than Merck for a defensive healthcare sector stock in a bear market. The A+ in Profitability is artificially buoyed by Lagevrio’s past performance. Without it, the Growth and Value Quants which are already graded ‘D’ are likely worse.
