The FDA has issued a press release regarding the approval of the first oral GLP-1 treatment for type 2 diabetes. Novo Nordisk also issued a press release on Rybelsus®. Novo Nordisk in the US issued a separate press release. In terms of future peak sales this might be the most important FDA approval of any drug this year.
Insulin has in recent years lost market share to drugs such as injected GLP1, oral SGLT2 and in particular oral DPP4 such as Januvia® from Merck and Trajenta® from Eli Lilly.
Novo Nordisk has annual sales of approximately $17B of which more than 80% originate from anti-diabetic drugs. The oral DPP4 drug Januvia® in 2016 reached worldwide peak sales of approximately $6B. Rybelsus® does not have the same side effects as DPP4 and it is not impossible imagining Rybelsus® reaching peak sales as high or higher than Januvia®. Sales of Victoza® and Levemir® will continue to shrink as they are cannibalised by their superior equivalents Ozempic® and Tresiba® and other drugs. But this deterioration will most likely be more than offset by Rybelsus® going forward.
The late stage clinical trial SOUL (NCT03914326) for oral semaglutide follows the phase 3 PIONEER studies. If this trial is succesful, then this could put Rybelsus® on par with other GLP1 class drugs in terms of major adverse cardiovascular events (MACE) and further boost sales of Rybelsus® in the decade ahead.
Additionally it is worth pointing out that injected semaglutide is already used for the treatment of obesity (Saxenda®) and oral semaglutide could very well be approved for the same purpose.
Novo Nordisk has with the approval of oral semaglutide for the treatment of type 2 diabetes (Rybelsus®) positioned itself well for the future. But the approval might have been expected by the market for the past few years and a lot of it might already be priced in as witnessed by the somewhat insignificant share price movement of approximately +2% following the approval.

All manufacturers of anti-diabetic drugs have issued press releases on their Q2 earnings. Novo Nordisk on August 9th and Eli Lilly on July 30th. And the 79th Scientific Sessions of the American Diabetes Association took place June 7-11, so a look at the changes in the diabetes landscape is due.
Worldwide sale of insulin continues to deteriorate, whereas the GLP1 class of drugs (e.g. Trulicity® from Eli Lilly and Ozempic® from Novo Nordisk) continues to grow within and outside the US.
The majority of the growth in the US is spearheaded by Lilly and the GLP1 drug Trulicity®, whereas Sanofi and their insulin Lantus® continues to descend lower.
The previous GLP1 bestseller Victoza® is descending from its peak sales, whereas Trulicity® is now the best selling GLP1 drug and Ozempic® the fastest growing. Interestingly semaglutide against obesity (Saxenda®) is turning into a blockbuster drug for Novo Nordisk. The GLP1 sale at Novo Nordisk could further accelerate, if oral semaglutide is approved by the FDA on 20th of September. Other noteworthy GLP1 news are summarised below. One of them regarding benefits of the phase III dual agonist tirzepatide from Eli Lilly. Another regarding the filing of oral semaglutide for FDA approval six months ago.

In terms of insulin, Lantus® from Sanofi is slowly bleeding to death in the US caused by the patent expiration and the launch of the analog Basaglar® by Eli Lilly. Levemir® from Novo Nordisk is also deteriorating in the US and this is not offset by growing sales of the newer Tresiba®. Similarly Humalog® from Eli Lilly will suffer in the coming quarters from the launch of a generic insulin Lispro by Eli Lilly itself and the analog Admelog® by Sanofi. Today and tomorrow belongs to the GLP1 class of drugs and not to insulin.

The SGLT2 drugs Farxiga® from AstraZeneca and Jardiance® from Eli Lilly continue to show positive growth in the US, whereas Invokana® from Merck displays negative growth. In the case of AstraZeneca SGLT2 is their fastest growing antidiabetic drug class. Recent news regarding the SGLT2 class of drugs are mentioned below.
Sep01 Detailed results from Phase III DAPA-HF trial showed Farxiga significantly reduced both the incidence of cardiovascular death and the worsening of heart failure
Aug20Farxiga met primary endpoint in landmark Phase III DAPA-HF trial for the treatment of patients with heart failure
Along with insulin the DPP4 class of drugs will probably be a loser going forward. Oral semaglutide, injected GLP1 and SGLT2 will continue to take market share from DPP4 going forward. The big loser will continue to be Januvia®/Janumet® from Merck, which is currently the best selling antidiabetic drug in the world with combined TTM sales just shy of USD 6B. Eli Lilly is planning to launch a combined SGLT2/DPP4 tablet according to the June press release below.

Novo Nordisk and Eli Lilly
The figures below summarise the sales for Novo Nordisk and Eli Lilly for individual drugs. For Novo Nordisk the losers are Levemir® and Victoza® and the future and current winner is oral and injected semaglutide (Ozempic®), respectively. Tresiba® is only partially offsetting the revenue loss by Levemir®. The big winner for Eli Lilly is Trulicity®. A future winner might be their phase III dual agonist, which is discussed elsewhere in this article. The insulin Basaglar® is cannibalising Lantus® and the SGLT2 drug Jardiance® is also doing well within and outside the US.
The table below summarises some of the ongoing or recently finished GLP1 studies from Sanofi, Eli Lilly and Novo Nordisk.
Eli Lilly is more than just Trulicity® and diabetes (e.g. Taltz®), but it is very richly valued despite terzepatide and other interesting drugs in the pipeline. Levemir® will continue to deteriorate for Novo Nordisk and Ozempic® will continue to cannibalise Victoza®, but a positive catalyst is the expected approval of oral semaglutide on September 20th; oral semaglutide could take market share from injected GLP1 (USD9B), SGLT2 (USD3B), DPP4 (USD8B) and insulin (USD18B). There is a lot of potential upside. Neither company is particularly attractive at current prices.
