at the baseline visit and follow a 12-week dosing schedule with either eptinezumab (100 or 300 mg) or placebo by
intravenous (IV) infusion. Patients who were assigned to placebo in the placebo-controlled treatment period, will be
randomly allocated to one of two treatment groups: eptinezumab 300 mg or eptinezumab 100 mg (n = 840).

Lu AG09222 (former ALD 1910) – phase I commenced in October 2019
Lu AG09222 is a monoclonal antibody (mAb) designed to bind pituitary adenylate cyclase-activating polypeptide
(PACAP), thereby effectively preventing PACAP from activating its receptors. PACAP has emerged as an important
signaling molecule in the pathophysiology of migraine and represents an attractive novel target for treating migraine.
Lu AG09222 may hold potential as a migraine prevention treatment for those who have an inadequate response to
other therapies and could provide another mechanism-specific therapeutic option for migraine patients and their
physicians. A phase I double-blind, placebo-controlled study of Lu AG09222 in approximately 100 healthy men and
women between the ages of 18 and 55, to assess the safety, tolerability and pharmacokinetic profile at various
doses, has completed (NCT04197349).

Brexpiprazole – phase III in Alzheimer’s agitation commenced in 2013
In April 2021 Lundbeck and Otsuka Pharmaceutical announced the decision to continue the recruitment of patients
in the phase III clinical trial of brexpiprazole in the treatment of agitation in patients with dementia of the Alzheimer's
type (NCT03548584). The decision to continue the trial is based on the results of an independent interim analysis,
supporting to progress the trial to the planned full enrollment of 330 patients.
The study is designed to assess the safety, tolerability and efficacy of brexpiprazole in the treatment of patients with
agitation in Alzheimer’s dementia. The trial consists of a continuous 12-week double-blind treatment period with a
30-day follow-up. The trial population is planned to include 330 male and female patients, aged 55–90 years, with
a diagnosis of probable Alzheimer’s disease.
The continuation of the study enables Lundbeck and Otsuka to further explore the efficacy of brexpiprazole to
address the high medical need in patients suffering from agitation in Alzheimer’s type dementia. Completion of the
trial is expected in the first half of 2022.
The primary outcome in the study is change in the Cohen-Mansfield Agitation Inventory (CMAI) Total score. The
key secondary outcome measure is change in the Clinical Global Impression – Severity of Illness (CGI-S) score, as
related to symptoms of agitation.
Brexpiprazole – phase III in Post-Traumatic Stress Disorder (PTSD) commenced in October 2019
Lundbeck and Otsuka Pharmaceutical have initiated a pivotal phase III program (n = ~577) investigating the use of
brexpiprazole in combination with sertraline in the treatment of PTSD (NCT04124614) subsequent to an End of
Phase II meeting with the US Food and Drug Administration (FDA) in May 2019.
PTSD is a psychiatric disorder that can develop as a response to traumatic events, such as interpersonal violence,
combat, life-threatening accidents or natural disasters. Core features of PTSD include a variety of symptoms, such
as re-experiencing phenomena (i.e. flashbacks and nightmares), avoidance behavior, numbing (i.e. amnesia,
anhedonia, withdrawal, negativism) and increased arousal (i.e. insomnia, irritability, poor concentration,
hypervigilance). Psychiatric co-morbidities are common, and PTSD sufferers can also present with substance
abuse, mood and other anxiety disorders, impulsive and dangerous behavior and self-harm.
