Lilly's Foundayo Obesity Pill Trails Novo's Wegovy in Early US Rollout

Foundayo's Launch Performance and Market Comparison

By Sriparna Roy

April 24 (Reuters) - Eli Lilly's newly launched weight-loss pill had a modest second week, analysts said on Friday, as competition with Danish rival Novo Nordisk heats up in the oral obesity drug market.

Prescription Data: Foundayo vs. Wegovy

The pill, launched earlier this month as Foundayo, was prescribed 3,707 times in the U.S. in the week ended April 17, IQVIA data shared by Wall Street analysts showed, up from 1,390 in its debut week.

Novo's Wegovy pill, launched in January, had clocked 18,410 prescriptions in its second week and 3,071 in the first four days after launch.

Analyst Expectations and Reactions

Analysts would have liked to see Foundayo's second-week prescriptions closer to around 8,000 "to show that its relative spread to the oral Wegovy launch was at least being maintained," said Deutsche Bank analyst James Shin.

RBC Capital Markets analyst Trung Huynh said while comparisons close to launch "should be considered immaterial, Foundayo's uptake this week is likely to be received negatively."

Market Impact

Lilly shares were trading nearly 4% lower, while U.S.-listed Novo shares were about 6% higher.

Foundayo prescriptions, totaling just 20% of what oral Wegovy achieved during its first full week, were "modest," noted Truist analyst Srikripa Devarakonda.

Rollout Dynamics and Investor Sentiment

Slower Ramp and Market Share Concerns

SLOWER RAMP

Investors are closely watching the rollout as a key test of whether Lilly can gain market share from Novo, which has had a first-mover advantage in the oral weight-loss drug market.

The prescription numbers represent a somewhat slower ramp compared to oral Wegovy, said J.P. Morgan analyst Chris Schott, adding that this was not surprising given Wegovy's advantages in time-to-market and brand recognition.

Distribution and Availability

Foundayo was approved in the U.S. on April 1, with prescriptions accepted immediately on LillyDirect, while shipping started on April 6. Broad availability through U.S. retail pharmacies and telehealth providers began on April 9.

Company Guidance on Early Data

Lilly previously cautioned that early weekly figures would not be fully comprehensive, may not capture the full breadth of pharmacy partners and would be "best interpreted over time rather than as a complete count."

Key Takeaways

  • Foundayo doubled week‑over‑week to 3,707 prescriptions by April 17, still far below Wegovy’s 18,410 in its second week (reddit.com).
  • Analysts expected Foundayo to reach closer to 8,000 scripts second week to maintain relative parity with Wegovy; its slower ramp drew skepticism (reddit.com).
  • Convenience may be Foundayo’s main advantage—it lacks Wegovy’s fasting restrictions—though analysts note its impact may be limited in driving broader uptake (biz.chosun.com).
