Eli Lilly executives confirmed on the April 30 Q1 call that a full direct-to-consumer TV advertising campaign for Foundayo (orforglipron) launches in late May 2026, coinciding with the mid-May commercial access activation at two of the three largest US pharmacy benefit managers. The campaign emphasizes Foundayo's only-oral-GLP-1-without-food-or-water-restrictions positioning vs Novo's Wegovy pill, which requires fasting administration. Lilly previously held back consumer advertising through the first six weeks of launch to let PBM coverage scale before driving consumer prescription demand. Citi's May 8 IQVIA note flagged the upcoming campaign and PBM expansion as the catalysts for the Week 5+ trajectory acceleration that landed in the May 8 IQVIA print (10,248 scripts, +40% w/w).
The next Foundayo IQVIA prescription tracker update is expected from Citi mid-week May 18-20, covering the week ending May 8. Week 4 hit 7,335 prescriptions per the May 8 Citi note with Lilly executives citing 20,000 total patients (~35% via telehealth not captured in the retail-only IQVIA data). Citi's projected $146M Q2 revenue and $1.6B full-year 2026 estimate continue to anchor the analyst consensus. Lilly executives have asked analysts for 8-12 weeks of data before reading commercial trajectory through pharmacy-fill noise; the Week 5 reading is the first post-PBM-coverage-expansion data point as the two largest US PBMs went live with Foundayo coverage mid-May. The Wegovy pill remains roughly 60-70x ahead on weekly volume (>440K in the week ending May 1 per Novo's Q1 commentary).
Novo Nordisk CEO Mike Doustdar confirmed on the May 6 Q1 analyst call and in May 14 follow-up commentary that the Wegovy pill has surpassed 1 million cumulative US users 16 weeks after the January 5, 2026 launch. The pill posted DKK 2.26B (~$354M) in Q1 sales (nearly 2x analyst consensus) on roughly 1.3 million Q1 prescriptions. Wegovy now holds 65% of all new US GLP-1 prescriptions per the Q1 IQVIA data. International expansion is targeted for H2 2026 with EU approval anticipated before year-end. The pill ramp is the cleanest near-term commercial signal for Novo against Lilly's tirzepatide franchise (Mounjaro/Zepbound), which displaced Keytruda as the world's #1 best-selling drug in Q1 2026.
IQVIA data cited by Deutsche Bank analysts and Pharmaphorum showed Novo Nordisk's Wegovy pill at roughly 113,354 prescriptions in its most recent reported week, up from 105,366 the week prior. That puts Novo's January-launched oral semaglutide more than 20× ahead of Lilly's Foundayo Week 3 reading of 5,612, and the gap is from US retail-channel data alone — NovoCare Pharmacy direct-to-consumer volumes are additional. Lilly executives have asked analysts to wait 8–12 weeks for a clearer read, but the early Foundayo-versus-Wegovy-pill comparison continues to favor Novo on raw volume.
Fierce Pharma's Oral GLP-1 Tracker reported May 1 that Eli Lilly's Foundayo (orforglipron) reached 5,612 prescriptions in the week ending April 24 — its third full commercial week — up roughly 51% from Week 2's 3,707 scripts but still behind the Wegovy pill's comparable third-week run. RBC and other analysts continue to caution that 8–12 weeks of data are needed to read commercial trajectory through pharmacy-fill noise. On the Q1 earnings call, Lilly USA's Ilya Yuffa said roughly 20,000 patients are now on the drug for obesity or overweight, calling the early launch 'encouraging.'
