How Phase 3 Sjögren’s Results At Amgen (AMGN) Has Changed Its Investment Story

Simply Wall St·09/26/2026 01:25:36
Listen to the news
  • Amgen reported positive topline Phase 3 OASIZ 301 data for dazodalibep in adults with moderate-to-severe systemic Sjögren’s disease, with statistically significant ESSDAI improvements sustained through Week 48 and a safety profile described as generally mild to moderate.
  • The readout highlights a potential first-in-class CD40L antagonist targeting a disease area with no approved disease-modifying therapies, which could broaden Amgen’s autoimmune portfolio and support the case for its late-stage pipeline focus.
  • The focus now turns to how Amgen’s broader investment narrative intersects with dazodalibep’s Phase 3 results in Sjögren’s disease and its future portfolio mix.

Amgen Investment Narrative Recap

To own Amgen, you have to believe the mix of established blockbuster therapies, biosimilars and a deep late stage pipeline can offset pricing pressure, biosimilar erosion and a relatively high level of debt. The dazodalibep Phase 3 win strengthens the case that autoimmune R&D spend is translating into late stage assets, but does not change the near term focus on execution across multiple programs.

The key short term swing factor remains whether Amgen can keep converting its large pipeline into approved, commercially relevant therapies while managing higher R&D and manufacturing investment. The biggest operational risk stays the same. Intensifying competition and drug price pressure could squeeze growth and margins if new launches and indications do not scale well.

The IMDELLTRA monitoring label update is especially relevant beside dazodalibep. Together they show Amgen working on both sides of the story: expanding the reach of newer oncology products while advancing autoimmune drug candidates aimed at underserved conditions such as Sjögren’s disease.

Shorter monitoring times for IMDELLTRA’s initial doses may make the treatment more manageable for community oncology clinics, which already treat most US cancer patients. That operational tweak supports adoption potential and complements the autoimmune pipeline progress. For investors tracking catalysts, execution across both IMDELLTRA and dazodalibep offers a real time read on how effectively Amgen is turning R&D into usable medicines.

What The Current Amgen Forecasts Assume

Exploring Other Perspectives

One alternative view you should know about focuses heavily on pricing pressure as the key risk. The most pessimistic analysts were expecting flat earnings around US$8.7b and revenue near US$38.9b by 2029, with a much lower implied value than consensus. Those pre-news estimates show how sharply opinions on Amgen can differ, so it is worth exploring several angles before you decide how this Sjögren’s update might reshape the story.
