Novo Nordisk 'Caught Short' By Lantus Exclusion
Novo Nordisk says it was caught by surprise when US pharmacy benefit managers decided to exclude Sanofi's basal insulin Lantus and downgrade its own Levemir from formularies in favor of Eli Lilly's soon-to-be launched biosimilar Basaglar. Novo had been hoping for more time to secure some of Lantus' US market share with its new diabetes product Tresiba, but now accepts that will not happen.
The diabetes market has been an area of significant pushback from payers and greater demands for rebates, putting pressure on sales. Novo Nordisk AS has been one of the most significant casualties, and cut its growth forecast for 2017 last month.

"People have said, 'but you knew the biosimilar was coming,'" said Novo Nordisk's IR manager Melanie Raouzeos at the Jefferies Healthcare conference in London on Nov. 16-17. "We did know it was coming, but we didn't expect that the PBMs would be so aggressive about accepting it. We thought it would be launched and then take its time to be accepted."
Novo Nordisk's basal insulin Levemir (insulin detemir) has always lagged behind Sanofi's Lantus (insulin glargine) in sales ($2.68bn in 2015 versus Lantus' $6.98bn), likely because of its comparatively late market entry.
With Lantus going off patent, both companies developed new drugs to shore up their diabetes franchises. Sanofi's Toujeo (insulin degludec) was approved by FDA in February 2015 and Novo Nordisk's Tresiba (insulin glargine) in September 2015. However, these have arguably modest benefits over their predecessors.
"Tresiba has had good market access, but we were forced to give higher rebates [than planned]. Biosimilar Lantus left us with no choice," said Raouzeos. Tresiba has been taking market share from Lantus and "cannibalizing Levemir," she added.
Novo Nordisk has said previously it plans to file its Victoza (liraglutide) follow-on product, semaglutide, in the US by the end of 2016.
Raouzeos noted that semaglutide was recently the second GLP-1 agonist to show positive results in a major cardiovascular outcomes trial (CVOT) in type 2 patients at high risk of CV disease. In the SUSTAIN-6 trial, semaglutide demonstrated a 26% risk reduction compared with placebo.
Victoza demonstrated CV benefit in the LEADER trial earlier this year.
Aside from diabetes, Novo Nordisk's hemophilia business faces a significant threat.
Competition is expected shortly in the form of Roche's late-stage promising bispecific antibody for hemophilia A, emicizumab (ACE910), which is being touted as a future blockbuster. Emicizumab, given once-weekly subcutaneously, has demonstrated prophylactic efficacy for people with severe hemophilia A, regardless of the presence of Factor VIII inhibitor antibodies (which develop in around 30% of hemophilia A patients), potentially streamlining treatment of this condition.
Currently, patients who develop inhibitor antibodies are treated with bypass agents such as Novo Nordisk's NovoSeven and Shire PLC's Feiba.
If approved, "50% of NovoSeven's sales are at risk," said Novo Nordisk's Raouzeos. Sales in 2015 were around $1.5bn.
However, despite $3bn in cash on its balance sheet and no debt, Novo Nordisk will not be adding "new legs" to its business, said Raouzeos. "In terms of business development, we're interested in add-ons or adjacent activity, but all M&A will be modest."
