Novo Nordisk has had a troublesome yr: a tumbling inventory worth ensuing within the greatest management shakeup within the firm’s 100-year historical past as buyers turned their again on the Danish drugmaker and its weight reduction enterprise.
It appeared buyers had largely given up on Novo’s capacity to translate its strides in pioneering GLP-1 medicine to monetary features because the profitable market attracts new gamers. Scientists, nonetheless, say that the medication nonetheless has potential.
What began with a concentrate on the drug’s capacity to handle weight and blood sugar, and fight associated situations reminiscent of coronary heart illness, is now increasing additional with rising curiosity in the way it may additionally affect the mind.
Semaglutide, or as it’s higher recognized, Ozempic and Wegovy, is a GLP-1 receptor agonist that was initially developed for diabetes sufferers to handle their blood sugar ranges. Nevertheless, it shortly grew to become prescribed by docs off-label en masse as its urge for food surpressing and weight-loss properties grew to become recognized. Right this moment, it’s accepted for anti-obesity functions and brings in billions yearly for its maker, Novo Nordisk.
Now, the medical neighborhood is discovering a rising checklist of added advantages from these medicine.
“Wegovy promotes weight reduction and doubtlessly different mechanisms not totally understood,” the U.S. Meals and Drug Administration wrote in a press release in August when it accepted the drug for treating liver illness. Semaglutide can be cleared by regulators to cut back the chance of coronary heart assaults and strokes in chubby folks with heart problems, in addition to to deal with continual kidney illness in diabetes sufferers.
In the meantime, a rival drug by U.S. competitor Eli Lilly, tirzepatide (referred to as Mounjaro and Zepbound), which additionally targets the GLP-1 hormone in addition to one other intestine hormone known as GIP, is accepted for treating average to extreme obstructive sleep apnea in adults with weight problems.
However the advantages could not finish there. Amid elevated competitors, extra indications have develop into a brand new frontier for drug builders alongside new codecs like capsules.
GLP-1s and the mind
Observational research have proven that GLP-1s seem to quiet cravings not only for meals, but in addition for alcohol, tobacco, and leisure medicine, as they have an effect on the mind’s reward pathway. By seemingly altering dopamine alerts within the mind, these medicine may scale back cravings and permit the person to be extra rational when confronted with tempting choices.
“There’s curiosity in understanding the potential of semaglutide on varied mind features,” Laura Nisenbaum, govt director at Alzheimer’s Drug Discovery Basis (ADDF), informed CNBC.
“Understanding that irritation and vitality utilization within the mind goes to be so essential for our regular cognitive operate,” Nisenbaum mentioned. Recognizing that hyperlink will probably be helpful in many alternative neurological and neuropsychiatric indications the place adjustments or harm to the mind affect temper, conduct or cognition, she added.
Evolving knowledge recommend that semaglutide and rival drug tirzepatide made by Eli Lilly could be the primary efficient “anticonsumption” brokers with the potential to deal with extreme meals cravings, weight problems, alcohol consumption, nicotine habit, leisure drug use, and even uncontrollable procuring behaviors, a examine by researchers at Saint Luke’s Mid America Coronary heart Institute and College of Missouri discovered.
One other small-scale randomized scientific trial discovered that low-dose semaglutide decreased alcohol consumption and considerably decreased cravings in comparison with placebo in sufferers with alcohol use dysfunction over 9 weeks of remedy. The outcomes justify bigger scientific trials of incretin therapies for alcohol use dysfunction, the researchers concluded.
The Alzheimer’s disappointment that wasn’t
One other potential added good thing about this class of medication could possibly be the way it interacts with the dementia course of.
In November, Novo upset buyers when it revealed knowledge on a two-year-long scientific trial testing whether or not semaglutide may decelerate cognitive decline in sufferers with Alzheimer’s illness.
Hopes had run excessive that the medication may be capable to assist folks affected by the commonest kind of dementia, because it had been noticed in real-world research that diabetes sufferers taking semaglutide developed Alzheimer’s at a decrease price than those that did not.
However the late-stage trial failed to satisfy its important objective, exhibiting that semaglutide did not considerably affect cognition in Alzheimer’s sufferers. Novo mentioned it will discontinue a one-year extension of the trial as a result of outcomes.
Nevertheless, some scientists informed CNBC it should not be seen as a failure. They are saying that even when the outcomes had been disappointing, it was a well-conducted trial that the science neighborhood was capable of study from.
“It simply gave a destructive outcome so far as the drug is anxious in that exact inhabitants,” mentioned Ivan Koychev, affiliate professor in neuropsychiatry at Imperial School London.
Semaglutide nonetheless, impacts Alzheimer’s illness proteins in the proper course, as seen in biomarker measures, Koychev mentioned. “They’re impacting Alzheimer’s disease-linked proteins, they scale back their amount within the cerebrospinal fluid, which means that it’s interacting instantly with the choice pathology.”
There was additionally an noticed discount in systemic irritation biomarkers, in accordance with Novo. “The considering is that it could be this anti-inflammatory impact that, whether it is carried out early sufficient within the illness course of, you possibly can considerably modify the chance of dementia,” Koychev mentioned.
“The sign was all the time within the prevention house moderately than the remedy house,” he added.
Equally, Nisenbaum mentioned a subsequent helpful step can be to check semaglutide and different GLP-1s earlier in the middle of the illness as a preventative remedy.
Novo Nordisk mentioned it was reviewing all knowledge from the trial, however that it was too early to invest any additional on the impact semaglutide may need on dementia sufferers.
The science versus the Road
Even if the improvements developed by Novo have the potential to considerably affect public well being, many buyers have turned their again on the corporate over the previous 18 months as its progress prospects face challenges.
Novo shares are having their worst yr on document since itemizing on Nasdaq Copenhagen over three a long time in the past. At its peak in mid-2024, the inventory traded at above 1,000 Danish kroner. Right this moment, it trades at round 320 kroner.
The inventory’s year-to-date drop of fifty% is being pushed by elevated competitors from U.S. rival Eli Lilly and so-called compounding pharmacies making cheaper, copycat variations of semaglutide. A failure to persuade buyers that its pipeline will deliver important monetary features amid a flurry of hopeful market entrants additionally provides to the stress.
Novo Nordisk shares within the year-to-date
The Alzheimer’s trial knowledge readout in November led shares to drop 5.8% on the day, regardless of analysts saying it was all the time a protracted shot and Novo administration themselves known as it a “lottery ticket,” — underlining its extremely unsure end result.
The 2 Alzheimer’s medicine at the moment available on the market, Eli Lilly’s Kisunla and Biogen/Eisai’s Leqembi have been proven to decelerate the development of Alzheimer’s illness by as much as a 3rd however include the chance of extreme negative effects.
These medicines had been studied 15 years in the past, and there have been many destructive research alongside the best way, ADDF’s Nisenbaum mentioned. “Every one, we realized one thing that then led to an enchancment in understanding our sufferers within the scientific trials after which learn how to measure what’s taking place in them.”
“It is completely in regards to the lengthy recreation,” she added, hopeful that semaglutide or different novel medicine that focus on danger elements could possibly be utilized in mixture with Kisunla and Leqembi.
However the market would not see it like that, and there are various the explanation why.
To begin with, buyers’ time horizons are a lot shorter than the decades-long course of it usually takes to deliver a drug to market, which means pharmaceutical growth usually clashes with the quicker tempo of public markets. Including new indicators for a drug additionally takes time, as they have to be backed up by usually prolonged scientific trials.
Secondly, semaglutide is going through key patent expiries in 2031 and 2032, which can give the inexperienced mild to others to make generic variations of semaglutide.
“We do not see a very good argument for a valuation ground,” Jefferies analysts mentioned late November, noting that Novo now enters the 5-year patent expiry window with no actual moat.
“Decrease U.S. costs could stimulate extra quantity demand and improve affected person retention, however we’re not of the view that, at these costs, generics and compounders can’t compete,” they added, ranking shares at Underperform.
Stress from the Trump administration to decrease drug costs for People, and the specter of excessive import taxes, have served as extra headwinds for Novo, in addition to for a lot of of its pharma friends over the previous yr.
Goldman Sachs analysts, led by James Quigley, are barely extra optimistic. “We stay Purchase-rated on Novo Nordisk, as whereas expectations have reset sharply downwards for close to/medium-term estimates, we proceed to imagine there could possibly be some quantity alternative for Novo because the weight problems market evolves,” they wrote in a notice late November.
“Whereas Novo are unlikely to take a number one share, we nonetheless see alternatives for Wegovy, CagriSema and oral Wegovy to drive worth in extra of what the market at the moment believes, though we acknowledge that this may seemingly take time and proof of an uptick in scripts earlier than buyers give credit score,” they added.
