With Leqembi Sales Trending Up, Biogen Gets Down to Brass Tacks: It Works

Biogen CEO Chris Viehbacher acknowledged that the company has finally overcome the initial hurdles surrounding Leqembi, its Alzheimer’s disease treatment, and is now shifting its focus towards the value proposition and treating patients.
Despite initial concerns over reimbursement and side effects, Leqembi has been gaining momentum, with quarterly sales of $87 million and a 30% quarter-on-quarter growth. The drug’s unique selling point lies in its ability to sustain plaque clearance, rather than just clearing the plaques initially.
Viehbacher expects this trend to continue, with IV maintenance formulations, and has made progress in relieving capacity constraints. However, he also cautioned that there are still challenges, such as expanding the prescriber network and improving diagnostic capabilities.
Indeed, the FDA has recently approved a monthly maintenance dosing regimen for Leqembi, which could provide a much-needed sales boost. This approval is based on modeling findings using data from a Phase II study and its long-term extension, as well as from the Phase III Clarity AD trial.
The approval was based on the finding that transitioning to a once-monthly maintenance schedule effectively sustains the clinical and biomarker benefits of treatment. Additionally, a monthly dosing schedule for Leqembi “may be easier for patients and care partners to continue treatment,” potentially helping with the drug’s uptake.
This development comes as Novo Nordisk is testing its GLP-1 against the disease in the Phase III Evoke and Evoke+ trials, which could potentially shift the standard of care in Alzheimer’s.

Breaking Through the Initial Hurdles
Navigating Reimbursement and Side Effects
There were concerns over the initial reimbursement and side effects of Leqembi, which Biogen is now addressing. The company has made progress in relieving capacity constraints, but there are still challenges to be overcome.
Biogen is testing Leqembi in a Phase III trial for patients with presymptomatic Alzheimer’s, with a key readout expected in 2028. The company is also testing BIIB080 in a Phase II trial for Alzheimer’s, which could provide further insights into the disease’s pathology.
Meanwhile, the European Union’s health regulatory agency has issued a negative opinion for Leqembi, citing concerns over the risk of serious side events. However, Eisai has asked for a re-examination of the negative opinion, which could lead to a positive opinion.
Sales Growth and Capacity Constraints
Quarterly Performance and Analyst Expectations
Leqembi sales have been growing, with quarterly sales of $87 million and a 30% quarter-on-quarter growth. However, there are concerns over capacity constraints, which Biogen is working to address.
Biogen CEO Chris Viehbacher expects the upward trend to continue, with IV maintenance formulations, and has made progress in relieving capacity constraints. However, he also cautioned that there are still challenges, such as expanding the prescriber network and improving diagnostic capabilities.
Analysts have noted that Leqembi uptake has been slow, with concerns over reimbursement barriers and the need to make providers aware of proper treatment. However, the recent approval of the monthly maintenance dosing regimen could provide a much-needed sales boost.
Sales Growth and Capacity Constraints
International Growth and Eisai’s Role
Leqembi sales have been growing internationally, thanks to Eisai’s marketing prowess in Asia. However, there are concerns over capacity constraints, which Biogen is working to address.
Biogen CEO Chris Viehbacher noted that outside of the U.S., sales growth is strong, which suggests that the company is on the right track. However, he also cautioned that there are still challenges to be overcome.
Eisai’s marketing efforts have been crucial to Leqembi’s success in Asia, where the drug has been approved for the treatment of mild Alzheimer’s disease and mild dementia or mild cognitive impairment.
The “Maintenance” Factor: Leqembi’s Unique Selling Point
Sustained Plaque Clearance vs. One-Time Treatment
Leqembi’s unique selling point lies in its ability to sustain plaque clearance, rather than just clearing the plaques initially. This differentiates the drug from competitor Eli Lilly’s Kisunla, which allows patients to stop taking the treatment once their plaques are clear.
The data show that Leqembi could stabilize about 76% of patients, which is a stat that needs to become central to demonstrating the value of the medicine. This is because Alzheimer’s disease progression does not stop after plaque clearance.
Ongoing treatment can also prolong the benefits of treatment and keep disease progression at bay, which is a critical aspect of Leqembi’s value proposition.
Boosting Accessibility
Subcutaneous Administration and Diagnostic Advancements
Streamlining Treatment with Subcutaneous Leqembi
Biogen is testing subcutaneous administration for maintenance treatment with Leqembi, which would bring the treatment into patients’ homes. This could potentially improve patient convenience and adherence.
The FDA has granted approval for subcutaneous administration for Leqembi, which is expected to begin making an impact in the latter half of the year.
Biogen is also testing diagnostic advancements, such as triage and early intervention strategies, to improve eligibility for treatment.
Boosting Accessibility
Addressing Diagnostic Challenges
Triage and Early Intervention Strategies
Biogen is testing triage and early intervention strategies to improve eligibility for treatment. This is critical, as approximately 50% of patients who manage to get into a neurologist are not eligible for treatment because they are too far advanced in their disease.
Improving diagnostic capabilities could help to identify patients who are eligible for treatment earlier, which could improve patient outcomes.
Biogen is also working to improve patient education and awareness, which could help to improve patient adherence and treatment outcomes.
Biogen’s Future in Alzheimer’s
Expanding Horizons Beyond Leqembi
The Quest for a Cure
Biogen is expanding its research efforts beyond Leqembi, with a focus on the quest for a cure for Alzheimer’s disease. The company is investing in new modalities, such as tau and other approaches.
Biogen is also testing BIIB080 in a Phase II trial for Alzheimer’s, which could provide further insights into the disease’s pathology.
Novo Nordisk is also testing its GLP-1 against the disease in the Phase III Evoke and Evoke+ trials, which could potentially shift the standard of care in Alzheimer’s.
Biogen’s Future in Alzheimer’s
The Competition
The Role of Novo Nordisk’s GLP-1 Entrant
Novo Nordisk’s GLP-1 entrant could potentially shift the standard of care in Alzheimer’s, which would be a significant development for the industry.
Biogen CEO Chris Viehbacher has noted that the company is watching the study closely, and that it is a worthy hypothesis. However, he also pointed to the long history of failure in drug development for the disease.
Biogen is continuing to invest in new modalities and approaches, which could help to improve patient outcomes and treatment options for Alzheimer’s.
