New Data Supporting the Safety and Efficacy Profile of AJOVY® (fremanezumab) Shared at 7th European Academy of Neurology Congress

  • Pooled analysis of fremanezumab Phase 3 studies indicates a positive cardiovascular safety profile in adult patients
  • Further data on injection-related adverse events provides fresh guidance for healthcare professionals in optimal selection of injection sites

AMSTERDAM--(BUSINESS WIRE)-- A new analysis presented by Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) on AJOVY® (fremanezumab) injection for the preventive treatment of migraine, indicates to the European neurology community that the medicine has a positive safety profile in relation to risk of cardiovascular events.

The data, drawn from an analysis of three published Phase 3 studies of fremanezumab and presented at the 7th Congress of the European Academy of Neurology (EAN), showed minimal changes in the heart rate and blood pressure of those patients studied over a 12 week period. 1

“As a CGRP inhibitor, fremanezumab has been shown to provide protection against migraine in suitable patients, and we remain focused on continued assessment of the safety profile of this therapy, particularly in relation to heart-related issues as it is believed CGRP itself acts as a ‘safeguard’ during cardiovascular ischemia and other events,” said Dr Joshua M. Cohen, Senior Director and Global Therapeutic Area Lead, Migraine and Headache, Teva.

“These new data offer the neurology prescribing community added confidence and further reassurance that any CV risks associated with fremanezumab use are minimal, particularly in relation to concerning issues such as hypertension.”

The data were arrived at following a pooled analysis of the HALO episodic migraine [EM], HALO chronic migraine [CM], and FOCUS Phase 3 clinical trials, which were designed to assess (fremanezumab) in the preventive treatment of migraine in adults.They are the first data to suggest that changes in heart rate and blood pressure remain unaffected by the action of any calcitonin gene-related peptide (CGRP) inhibitor when used at its recommended dose.

Fremanezumab, a fully-humanized monoclonal antibody (IgG2Δa), selectively targets the CGRP ligand.1 Potential effects of CGRP inhibition are important for patients as this peptide has been described to have a cardioprotective role, particularly during ischemic events, and migraine patients are well known to carry a potentially higher risk of stroke and myocardial infarction.2

Across the phase 3 studies, 1,897 patients received fremanezumab (quarterly, n=943; monthly, n=954) and 945 received placebo. At the end of 12 weeks of double-blind treatment, mean increases from baseline in heart rate (measured in beats per minute) were minimal, as were decreases in systolic (SBP) and diastolic (DBP) blood pressure (measured in mmHg) for the population studies. None of these changes were deemed clinically significant.1

“EAN is among the premier annual meetings for professionals invested in the ongoing improvement of clinical practice in neurology,” said Dr Cohen.

“Teva is excited to continue its close working partnership with the Academy and is grateful to have this important platform to deliver fresh insights on the cardiovascular profile of fremanezumab and give neurologists more evidence and confidence in its use as an important migraine therapy.”

Additional data presented confirms most adverse events occur within the first month of treatment and are more common in the limb than abdominal region

Further data taken from the pooled analysis of HALO EM, HALO CM, and FOCUS may improve the guidance prescribers can give to patients around managing potential issues at injection sites.

Injection site adverse events were shown to be most common in the first month following the start of treatment, and when taken quarterly or monthly, were seen to be more common in a limb rather than the abdomen.

“Most injectable therapies carry a risk of adverse events at the injection site, and our data are providing some useful guidance that could indicate abdominal injections may be a preferable choice for patients, where fewer events were detected as opposed to injection via a limb. This may feel like a relatively small consideration in the grander scheme of assessing overall efficacy and safety, but it is an important consideration for individuals who have been prescribed the medicine,” said Dr Cohen.

This pooled analysis included 2,842 patients. In the quarterly fremanezumab (n=943), monthly fremanezumab (n=954), and placebo (n=945) groups, respectively, injection-site AEs were reported for 37%, 37%, and 31% of patients, most commonly pain (22%, 20%, and 20%), induration (15%, 18%, and 13%), and erythema (16%, 15%, and 12%). These AEs were most common within the 1 month of initiating study treatment. With quarterly fremanezumab, monthly fremanezumab and placebo, injection-site AEs were more common in the limb than in the abdomen.3
