Scientific breakthroughs in uncommon illness are coming at a sooner clip as know-how improves. However commercializing these medicine to a small inhabitants stays a problem, and uncommon illness specialist Alexion has needed to pave many new roads alongside the best way.
Chief amongst these hurdles are discovering the sufferers recognized with a sure situation and dealing with regulatory our bodies to design a mechanism for approval. Alexion’s senior vice chairman of the U.S. enterprise, Scott Weintraub, views these obstacles as a chance to be the primary firm that tackles particular unmet wants.
Now a part of pharma big AstraZeneca after a $39 billion buyout that closed in 2021, Alexion’s technique requires much more foresight and communication between disparate departments of R&D and business than firms growing medicine for extra widespread situations, he stated.
“Within the Venn diagram between improvement and commercialization in uncommon illnesses, the center is fairly giant, as a result of you need to take into consideration these items early on,” Weintraub stated. “It’s going to be extra than simply the drug profile, which is clearly necessary, however can you discover these sufferers?”
From finding sufferers to offering proof to regulators, all the pieces is somewhat bit more durable while you’re on the innovative.
“Should you’re the primary, you may have much more to do than simply promoting the drug,” Weintraub stated. “Quite a lot of occasions, you don’t have a path ahead with the FDA on the time of your thought, so you need to persuade them as to what’s necessary to those sufferers.”
Weintraub says that uncommon illness drug improvement must “begin with the top in thoughts.”
Charting new waters
Strensiq is a drug that exemplifies these challenges, Weintraub stated. The therapy for a uncommon bone situation referred to as hypophosphatasia addresses a illness that’s sometimes troublesome to diagnose in infants and youngsters with fragile bones. The illness also can have a later onset, and it’s typically misdiagnosed as fibromyalgia.
On the floor, what ought to be a market the place Alexion has no competitors is hard to penetrate as a result of sufferers aren’t readily obvious — the corporate needed to be taught over time what number of sufferers existed.
On the similar time, the unique formulation of Strensiq requires a number of injections per week for the remainder of a affected person’s life, a routine that has evoked emotional pleas to chop down on the variety of pictures, Weintraub stated. Now, Alexion is conducting a late-stage trial with fewer injections and a wider pool of sufferers.
“Sufferers within the trial have damaged down in entrance of medical doctors, their life totally consumed by getting their son these injections. That they’d have the ability to management his illness with a shot as soon as each different week and never be reminded of it daily was actually impactful for them,” Weintraub stated.
Weintraub stated these classes from the affected person neighborhood are particularly necessary in uncommon illness.
“The entire challenges and alternatives in uncommon illness are troublesome for improvement, they usually’re troublesome for commercialization — however on the similar time, we might name that mission the key sauce of Alexion,” Weintraub stated. “Should you’re in accounting or in a bench laboratory, you all know the mission.”
Following Soliris
The enterprise of follow-on medicine isn’t new to the corporate. As Amgen was getting ready to launch a biosimilar of Alexion’s paroxysmal nocturnal hemoglobinuria blockbuster drug Soliris in March subsequent yr, Alexion was racing the clock to ship a brand new model referred to as Ultomiris. Their mission was not solely to get the drug permitted, which occurred in 2018, however to persuade sufferers to change.
In the course of the AstraZeneca acquisition, the sustainability of the Soliris enterprise was a key concern. And for uncommon illness sufferers, a part of that answer was to scale back the injection burden from as soon as each two weeks to solely six occasions a yr.
“Quite a lot of these questions have gone away,” Weintraub stated, pointing to Ultomiris’ decrease dosing routine in addition to a 30% cheaper price in comparison with Soliris despite the fact that Ultomiris may have been offered at a better worth level. Alexion has additionally been exploring different indications for, gaining approval in 2022 for the uncommon neuromuscular illness generalized myasthenia gravis, or gMG, and most not too long ago this yr for neuromyelitis optica spectrum dysfunction.
“Should you’re the primary, you may have much more to do than simply promoting the drug. Quite a lot of occasions, you don’t have a path ahead with the FDA on the time of your thought, so you need to persuade them as to what’s necessary to those sufferers.”

And with AstraZeneca on board, Alexion, which had beforehand operated in about 20 nations, has entry to 70 markets worldwide.
In all of these markets, doctor schooling is paramount to Alexion’s success, Weintraub stated.
“A neurologist who has two gMG sufferers has a variety of questions on scientific trial knowledge or real-world proof, or the protection of X, Y and Z therapies,” Weintraub stated. “If gMG was a paragraph of their medical books after they went via faculty, we are able to present extra worth to them over time.”
Mockingly, the work Alexion does to pave the best way in uncommon illnesses additionally results in additional competitors down the street — “as a result of we created a pathway for drug approval, and as soon as that mechanism is in place, different firms can not less than get their drug permitted and determine their technique.”
AstraZeneca’s promise
AstraZeneca CEO Pascal Soriot earlier this yr promised 20 new medicines launched by 2030 and whole income above $80 billion. As a $6 billion enterprise unit, Weintraub stated, Alexion’s leaders hope to have an outsized impression on reaching these objectives.
“We’ll have not less than a pleasant sized portion of the brand new molecular entities, and Alexion will punch above its weight to contribute to that,” Wintraub stated, stating the corporate has 10 section 3 applications within the works.
At AstraZeneca, Alexion now has entry to a cutting-edge genetics portfolio that the pharma big had been accumulating over time via biotech funding. Alexion additionally gained know-how within the fields of analysis and affected person monitoring that make discovering unmet uncommon illness wants simpler than ever earlier than.
“If you concentrate on the diagnostic problem, it takes a mean of practically 5 years and 7 completely different specialists to even get the correct analysis,” Weintraub stated. “You’ll be able to’t simply go to market — you need to assist with analysis and schooling across the globe, and perceive the affected person journey and what’s significant to them by way of enchancment.”
