Eli Lilly's Kisunla Shows Sustained Benefits in Alzheimer's Disease Over Three Years

Long-Term Benefits of Kisunla in Alzheimer's Treatment

Introduction

Eli Lilly and Company has recently announced promising findings from the long-term extension (LTE) of the Phase 3 TRAILBLAZER-ALZ 2 study for Kisunla (donanemab-azbt), a treatment targeting early symptomatic Alzheimer's disease. The results indicate that not only does Kisunla show sustained clinical benefits over an extended period, but these benefits significantly improve when treatment begins early.

Study Background

The TRAILBLAZER-ALZ 2 study focused on assessing the efficacy and safety of Kisunla in individuals with early symptomatic Alzheimer's. With a Phase 3 design, the LTE portion of the study monitored participants who either continued their initial treatment with Kisunla or transitioned from a placebo group to Kisunla. An external comparator group from the Alzheimer's Disease Neuroimaging Initiative (ADNI) provided context for evaluating the treatment's effectiveness against an untreated cohort.

Key Findings

1. Sustained Clinical Benefits: The data revealed that participants receiving Kisunla experienced a significant slowing of cognitive decline over three years. Specifically, participants initially treated with Kisunla demonstrated a reduction in cognitive decline, showing a change of -0.6 at 18 months and -1.2 at 36 months on the Clinical Dementia Rating Sum of Boxes (CDR-SB) scale compared to the ADNI cohort.
2. Impact of Early Treatment: Earlier initiation of Kisunla was particularly beneficial, reducing the risk of disease progression by 27% on the Clinical Dementia Rating-Global Score (CDR-G).
3. Amyloid Clearance: Over 75% of those treated with Kisunla achieved significant amyloid clearance within 76 weeks. Furthermore, those observed for up to 2.5 years post-treatment continued to show slow rates of amyloid plaque reaccumulation, indicating sustained effects.
4. Safety Profile: No new safety signals were identified throughout the three-year LTE period, reinforcing the medication's established safety profile. While some potential side effects were noted, including amyloid-related imaging abnormalities (ARIA), the overall safety remains consistent with previous studies.

Insights from Researchers

Dr. Mark Mintun, Group Vice President at Eli Lilly, stated, "The TRAILBLAZER-ALZ 2 long-term extension reaffirms that Kisunla delivered sustained clinical benefit that continued to increase over three years and a consistent safety profile. Participants continued to show meaningful outcomes, reinforcing the long-term value of early intervention." This suggests that initiating treatment sooner can yield better health outcomes and longevity in cognitive function.

Broader Implications

The results underscore the advantage of early intervention in Alzheimer's disease management, possibly shifting clinical practices towards prioritizing timely treatments. Eli Lilly's ongoing work with Kisunla reflects a larger commitment to understanding and combating Alzheimer's, including trials such as TRAILBLAZER-ALZ 3 and TRAILBLAZER-ALZ 5, furthering the understanding of Alzheimer's from preclinical stages to symptomatic disease.

Conclusion

The findings from the TRAILBLAZER-ALZ 2 LTE study provide strong evidence supporting the efficacy and safety of Kisunla as a viable treatment option for early symptomatic Alzheimer's disease. As research continues, the hope is to redefine treatment timelines and improve quality of life for millions affected by this progressive condition.
