Signals

Short reads on the leading indicators we are tracking - clinical, regulatory, operational. Each Signal answers what is moving, what we know, and what we are watching next.

Signals are deliberately short. When the picture firms up enough to synthesize, a Signal grows into an Insight.

The "clinically meaningful" debate around CDR-SB is not settling

The interpretive argument over whether a sub-half-point CDR-SB delta represents a clinically meaningful slowing of decline continues to shape regulatory, payer, and clinician views.

Donanemab introduces a finite-duration treatment model

NICE's rejection of lecanemab and donanemab is widening the transatlantic access gap

Final NICE guidance declined both anti-amyloid antibodies for routine NHS use on cost-effectiveness grounds. The same products are reimbursed in Germany and approved (with payer fragmentation) in the US. The bifurcation is hardening rather than resolving.

Donanemab's limited-duration treatment paradigm is reshaping the lifetime cost calculation against lecanemab

Donanemab's protocol stops dosing once amyloid clearance is achieved, typically 12-18 months. Lecanemab is continuous indefinitely. Over a 10-year treatment horizon, the implied lifetime cost difference is substantial.

Tau PET reimbursement is the next diagnostic access question

Amyloid PET has settled into routine coverage and availability. Tau PET - which will be the confirmatory pathway for tau-directed therapies - is sited at meaningfully fewer centers and reimbursed unevenly. The access conversation that defined anti-amyloid rollout is about to repeat, one mechanism later.
