Quick status check on Novo, Lilly, and rivals after ADA 2025 – just ahead of Q2 earnings.
Introduction
Novo Nordisk and Eli Lilly will release their Q2 results on 6 and 7 August.
ADA 2025, which wrapped at the end of June, delivered a blitz of new obesity data. Below is a look at every major piece now on the board—and the ones most likely to move next in this century-old contest between the two weight-loss giants. (Need a refresher on the previous board set-up? Check the earlier post.)
Candidates and products on the board
After ADA 2025 we got fresh topline data on three fronts:
• Amycretin (Novo Nordisk, phase 1 – weekly shot and daily pill)
• MariTide / Maridebart cafraglutide (Amgen, phase 2 – monthly shot)
• Orforglipron (Eli Lilly, phase 3 – daily pill in T2D patients).
The first table summarises the key pieces now in play. Except for Orforglipron (a small-molecule GLP-1) and Bimagrumab (a muscle-preserving mAb), every candidate is a GLP-1 receptor agonist or combo. Bimagrumab stays on the board because the phase 2 BELIEVE read-out of the bima + sema combo (NCT05616013) was showcased at ADA 2025, and analysts see a > $30 billion market for muscle-preserving obesity drugs by 2035.
The second table drills into weight-loss studies that excluded hyperglycaemic/diabetic patients.

What to listen for on the Q2 earnings calls
Novo Nordisk — 6 Aug
- CEO hand-off – any hint on who follows Lars Fruergaard Jørgensen?
- Manufacturing headroom – has Wegovy capacity finally outpaced demand, and will it scale for Amycretin?
- Amycretin phase 3 design – trial size, endpoints, and the split between oral and injectable arms.
- CagriSema filing – timeline clarity after the REDEFINE data.
- Oral sema 25 mg – likely no news; FDA already accepted the OASIS-4 filing, PDUFA sits in Q4.
Eli Lilly — 7 Aug
- Orforglipron phase 3 – guidance now or pushed to the promised Q3 update?
- Bimagrumab phase 3 – has the trial design been finalised with FDA, or is it still pencilled in for Q4?
- Retatrutide phase 3 – first-patient-in date, dosing cadence, any early enrolment colour?
Wild-cards
- Amgen – could outline the MariTide phase 3 program (monthly shot).
- Boehringer Ingelheim / Zealand – may drop an enrolment update on Survodutide’s SYNCHRONIZE-1 trial in non-T2D patients.
End-game snapshot – who is up on the board?
Current position
- Lilly is a pawn ahead in market play: Zepbound still edges Wegovy on kilos lost.
- Novo answered with a bold move: the Amycretin shot posted -24.3 % in phase 1 and, after buying Catalent, Novo controls more fill-finish capacity to feed future demand.
Key squares to watch next turn
- Safety file – GI events and dropout rates at high doses.
- CVOT lane – hard-outcome trials will crown the real king.
- Manufacturing lane – Catalent integration must unblock Wegovy and prep Amycretin.
Scorecard
- In-market pieces: advantage Lilly.
- Late-stage pipeline: even – Retatrutide vs Amycretin.
- Oral game: Lilly up a tempo with SMD Orforglipron; Novo’s high-dose oral sema trails, Amycretin pill is the dark horse.
Next move (Q2 calls, 6-7 Aug)
Updates on supply chain, phase 3 starts, CV signals, and CEO succession (Novo) could swing initiative. The first player to pair mega weight loss with clean CV data will own the board.
