PEARL STUDY Interim data presented at the European Academy of Neurology 2022 shows that 54.7% of patients in the study had their monthly-migraine-days reduced by 50% or more over the six-month period from the start of treatment.
25th June 2022: Teva Pharmaceuticals Europe B.V. announced promising interim results from its Pan-European Real World study (PEARL), presented for the first time at the European Academy of Neurology (EAN) Congress in Vienna, Austria.
The two-year Pan-European Real World (PEARL) prospective, observational study of AJOVY® (fremanezumab), looks at its effectiveness in patients with chronic migraine or episodic migraine, and is an ongoing study sponsored by Teva Pharmaceuticals Europe BV.[i] These findings further offer insight into the treatment of migraine in real-world clinical practice.
The interim findings were presented by Faisal Mohammad Amin, Associate Professor of Neurology at the University of Copenhagen, Denmark. Out of the total planned 1100 patients in PEARL, 389 patients are included in the interim analysis presented. These findings show that 54.7% of patients in the study had their monthly-migraine-days reduced by 50% or more, over the six-month period from the start of treatment. Additionally improvements could be seen in migraine-related disability in the six-month period after the first dose.
The study is particularly relevant to clinicians due its patient cohort, who come from 11 countries and approximately 100 study centres.1 This patient group illustrates both diverse populations and also a range of reimbursement settings which are important for treatment access in Europe.
The study will continue to capture data on effectiveness, and safety of fremanezumab, as well as the reason for and the outcomes of stopping and re-starting treatments.
Commenting on the findings, Professor Messoud Ashina, PEARL Coordinating Investigator from the Danish Headache Center and Department of Neurology in Rigshospitalet Glostrup, Denmark, said:
Patients with severe migraine could benefit from preventive therapy but usage of those treatments is far from optimal. These interim findings provide real-world evidence of how the burden of migraine can be reduced when the patient has access to monoclonal antibodies like fremanezumab – something neurologists around the world are already seeing in patients who did not respond to previous preventive treatments.
Dr. Danilo Lembo, Vice President and Head of EU Medical Affairs at Teva, said: “The PEARL study is encouraging as these findings confirm that preventive treatment of chronic and episodic migraine is appropriate with fremanezumab in a real world setting. Our commitment to real-world evidence studies helps clinicians to better understand the lived experience of people with migraine, support the evolution of best clinical practice and demonstrate the impact of migraine and what preventive treatments can achieve. ”
The real life experience of European patients being able to access preventive treatment is bleak. Beyond our own data and research, a recent study from the European Migraine and Headache Alliance showed that 40% of patients needed more than five years to access migraine treatments.[ii] We need real structural change to come from healthcare systems if we are to ultimately reduce the burden of migraine.Dr. Danilo Lembo, Vice President and Head of EU Medical Affairs at Teva
Chronic migraine is defined as a headache occurring on 15 or more days per month for more than three months, which, on at least 8 days per month, has the features of migraine headache;[iii] episodic migraine is defined as having headaches on fewer than 15 days a month.[iv] The significant personal impact and burden of this severity of migraine has been shown in many studies including Teva’s own survey of 12,545 adults with migraine – ‘Beyond Migraine’, in which 45% said migraine impacts their ability to be a good partner and 42% to be a good parent, while 49% said migraine diminished their ability in the workplace. In terms of broader social impact, 46% reported hiding migraine from others.[v]
41 million people in Europe live with migraine[vi] and the disease is three times more common in women.[vii] Migraine is the second leading cause of disability in the world and the first among young women.[viii] Migraine often begins at puberty and mostly affects people aged between 35 and 45 years.[ix] It strikes during people’s most productive years (late teens to 50s).[x]
A publication in the journal Headache presented data that shows, for AJOVY®, there is no reduction in efficacy over a dosing period. This means that the efficacy of AJOVY® was similar at the end of the dosing period compared to the start of the same dosing period, immediately following treatment admininistration. Patients using AJOVY® therefore experience the benefits of treatment throughout the entire dosing period. See Blumenfeld AM, Stevanovic DM, Ortega M et al. No “wearing-off effect” seen in quarterly or monthly dosing of fremanezumab: Subanalysis of a randomized longterm study. Headache 2020; 60: 2431–2443.

The Pan-European Real World (PEARL) study will generate important information about real-world effectiveness of fremanezumab in adult patients with chronic migraine or episodic migraine (EM). PEARL is an ongoing, 24-month, multicentre, prospective, observational, Phase IV study.
PEARL will evaluate:
- Treatment adherence and persistence
- Effectiveness in patients switching from another mAb targeting the CGRP pathway
- Concomitant preventive and acute migraine medication use
