Foundayo IQVIA Week-Ending-May-15 Tracker: ~17,000 Prescriptions vs Wegovy Pill ~142,000 — Lilly's First Above-15K Print Narrows but Doesn't Close the Trajectory Gap

IQVIA's weekly prescription tracker for Foundayo (orforglipron) hit approximately 17,000 prescriptions for the week ending May 15, 2026, per Citi's Friday client note — Lilly's first above-15,000 weekly print since the April 6 launch. The week-by-week trajectory: 1,390 (Week 1), 3,707 (Week 2), 5,612 (Week 3), 7,335 (Week 4), 10,248 (Week 5), and ~17,000 in the new print. Novo Nordisk's Wegovy pill recorded roughly 142,000 prescriptions in the same week — the trajectory gap is narrowing as Foundayo's PBM coverage activates at the largest US plans but still remains 8.3x the Foundayo volume. Citi maintains $146M Foundayo Q2 revenue and $1.6B 2026 full-year estimates; the IQVIA print supports the trajectory. Lilly's late-May TV-advertising launch may amplify the next leg of Foundayo growth heading into mid-June.

Wegovy Total Scripts Hit 446,000/Week with 40.5% Obesity GLP-1 Market Share — Injectable Strength Holds Despite First Pill Decline

Even with the first weekly Wegovy pill prescription decline since launch (~143K to ~137K week-ending May 8), the total Wegovy franchise (injectable + pill) climbed 1.3% week-over-week to approximately 446,000 prescriptions per the Fierce Pharma IQVIA tracker. Market share in the US obesity GLP-1 segment ticked up 0.1 percentage points to 40.5%. The injectable Wegovy 2.4 mg and Wegovy HD 7.2 mg formulations remain Novo's commercial anchor; the pill is the growth narrative. The 1.3% w/w injectable Wegovy growth aligns with Novo's H2 2026 international expansion plans and the EU approval expected before year-end. The data also confirms Zepbound (tirzepatide for obesity) continues to grow share faster than Wegovy on an absolute volume basis — the head-to-head dynamic that Cantor Fitzgerald and Barclays both cited in their May 5 LLY price target raises.
