While the new Alzheimer’s disease medicine Leqembi has generated lots of buzz since its debut this year, one research team is investigating whether the medicine holds promise in preventing disease progression before any Alzheimer’s symptoms are evident.

In this week's episode of "The Top Line," Fierce Pharma’s Eric Sagonowsky talks with the study lead, Reisa Sperling, M.D., to learn more.

Exploring the promise of earlier Alzheimer's treatment

In this sponsored episode of The Top Line, host Stephanie Butler is joined by Sheila Plant, vice president of regulatory affairs at Allucent, to examine how FDA Breakthrough Therapy and RMAT designations can support more strategic oncology development. 

Although both pathways are intended to speed development, they are not interchangeable. Plant outlines the key distinctions, noting that Breakthrough Therapy requires evidence of substantial improvement over existing treatments, while RMAT is available for regenerative medicine therapies and centers on preliminary clinical evidence indicating the potential to address unmet medical needs. 

The conversation also explores the strategic choices that determine whether sponsors are ready to pursue these designations, from building a credible data package to designing trials with clinically meaningful endpoints and keeping manufacturing readiness aligned with development timelines. 

Once a designation is granted, closer collaboration with the FDA can help sponsors navigate development with more dynamic feedback. But as Plant emphasizes, these pathways deliver the greatest value when they are part of a disciplined regulatory strategy. 

Listen now to learn how sponsors can approach expedited pathways with greater clarity and position oncology programs for meaningful acceleration.

FDA Breakthrough Therapy and RMAT: Strategic Decisions That Can Accelerate Oncology Development (Sponsored)

In this episode of “The Top Line,” recorded on site at Fierce Biotech Week in Boston, Fierce’s Ayla Ellison sits down with Christelle Huguet, Ph.D., executive vice president and head of R&D at Ipsen, to discuss how the company is building its pipeline through external innovation while maintaining internal scientific accountability.

Huguet explains Ipsen’s approach to partnering, describing the company as an “accelerator” that helps move promising science from academic labs and biotech partners toward patients. She also discusses how Ipsen evaluates which programs move forward, why transparency with partners is essential from the start and what the company is watching as it heads into a year with several key clinical and regulatory milestones.

Ipsen R&D chief on pipeline discipline, partnerships and 2026 milestones

Marker 01

In this sponsored episode of The Top Line, experts from Myriad Genetics join host Stephanie Butler to examine how tumor-informed molecular residual disease, or MRD, testing is beginning to redefine what early insight can mean in oncology drug development. As biomarker-driven therapies become more precise, the ability to understand response earlier and more clearly is increasingly being viewed as foundational to smarter development strategy.

The discussion looks at how ultrasensitive, tumor-informed MRD assays can help track response over time, potentially surface deeper signals earlier and inform decisions that shape trial design, patient selection and regulatory direction. It also considers why these capabilities may become more important as oncology programs face growing pressure to balance speed, flexibility and evidence generation.

Listeners will hear why early diagnostic strategy is increasingly seen as a competitive differentiator, how MRD can help teams make better decisions sooner and why its role in oncology development is expected to continue to evolve and expand.
