Extension Study of ABP-20001 to Evaluate Safety and Efficacy of Repeat Treatments of ABP-450 for Migraine Prevention
- Conditions
- Migraine
- Interventions
- Drug: ABP-450
- Registration Number
- NCT05016661
- Lead Sponsor
- AEON Biopharma, Inc.
- Brief Summary
This Phase 2 Extension trial will evaluate the efficacy and safety of ABP-450 for migraine prevention in adults who suffer from six or more migraine days per month. The study will enroll approximately 666 patients across approximately 65 sites in the United States, Canada and Australia from the Phase 2 trial. Study subjects will be divided evenly across a low dose group and a high dose group. All patients will receive four treatment cycles of ABP-450 utilizing the Company's novel injection paradigm.
- Detailed Description
The Phase 2 Extension trial will evaluate the efficacy and safety of ABP-450 for migraine prevention in adults who suffer from six or more migraine days per month. The study will enroll approximately 666 patients across approximately 65 sites in the United States, Canada and Australia from Phase 2 trial. Study subjects who had their initial dose of study drug in Phase 2 trial study, irrespective of treatment allocation, will be eligible to enroll in this extension study. Study subjects will be divided evenly across a group receiving a low dose of ABP-450 and a group receiving a high dose of ABP-450. All patients will receive four treatment cycles utilizing the Company's novel treatment paradigm involving fewer injections than the current botulinum toxin treatment option for chronic migraine.

Medical Conditions:
-
History of migraine accompanied by diplopia or decreased level of consciousness, or retinal migraine.
-
Current diagnosis of chronic tension-type headache, new persistent daily headache, trigeminal autonomic cephalgia (eg, cluster headache), or cranial neuropathy.
-
Confounding and clinically significant pain syndromes (eg, fibromyalgia, chronic low back pain, complex regional pain syndromes) as evaluated by the investigator.
-
Diagnosis of myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other significant neuromuscular disease that might interfere with the study.
-
Psychiatric conditions that are uncontrolled and/or untreated as evaluated by the investigator.
-
Lifetime history of psychosis, mania, or dementia.
-
History of addiction, including alcohol or drug abuse since initiating ABP-20001 study treatment.
-
Any infection or clinically significant skin problem in any of the injection sites.
-
Any medical condition (including but not limited to viral or other active infections) that, in the opinion of the investigator, classifies the patient as unsuitable for participation in the study or patients who do not seem to be in good general health at the time of signing the ICF, and prior to any investigational study drug administration.
Note: Patients will not routinely be tested for COVID-19 during the study. Patients presenting with fever or who are symptomatic for COVID-19 will be required to be tested and treated through their general practitioner.
Other Diagnostic Assessments:
-
Significant risk of self-harm based on clinical interview and responses on the C-SSRS, or of harm to others in the opinion of the investigator; patients must be excluded if they report suicidal ideation with intent, with or without a plan (ie, Type 4 or 5 on the C-SSRS) in the time since enrolling in Study ABP-20001.
Prior/Concomitant Medications and Treatments
-
Injection with anesthesia or steroids in the targeted muscles since initiating ABP-20001 study treatment.
-
Use of opioids or barbiturates >2 days per month since initiating ABP-20001 study treatment.
-
Use of CBD or other types of cannabinoids since initiating ABP-20001 study treatment.
-
Use of botulinum toxin for migraine or any other medical reasons, including cosmetic use, at or above the shoulders outside of Study ABP-20001 since initiating ABP-20001 study treatment and throughout Study ABP-20002.
-
Any CGRP inhibitor treatment (eg, erenumab [Aimovig®], eptinezumab [Vyepti®], fremanezumab [Ajovy®], or galcanezumab [Emgality®], rimegepant sulfate [Nurtec™], ubrogepant [Ubrelvy™] within or outside of a clinical study) since initiating ABP-20001 study treatment.

Group Intervention Description ABP-450 - Low Dose ABP-450 ABP-450 Low Dose - intramuscular injections into specified muscles. ABP-450 - High Dose ABP-450 ABP-450 High Dose - intramuscular injections into specified muscles
- Primary Outcome Measures
Name Time Method Incidence of Treatment Emergent Adverse Events Baseline to Week 52 - End of Study The primary safety endpoint will be the incidence of TEAEs throughout the study when dosed with ABP-450 (low dose) or ABP-450 (high dose).
Change in Monthly Migraine Days Baseline to Week 52 - End of Treatment Period The primary efficacy endpoint will be the change in mean Monthly Migraine Days (MMD) from Baseline to intervals throughout the study.
- Secondary Outcome Measures
Name Time Method Mean change in Monthly Migraine Days (MMD) requiring medications for acute treatment of migraine or headaches Baseline to Week 52 - End of Study Overall mean change from Baseline in number of MMD requiring migraine specific medication and non-specific medications for the acute treatment of migraine or headache will be assessed by Treatment Group.
Mean change in Headache Hours Baseline to Week 52 - End of Study Overall mean change from Baseline in headache (either moderate or severe) hours will be assessed by Treatment Group.
Mean Change in Monthly Headache Days Baseline to Week 52 - End of Study Overall mean change from Baseline in monthly headache days will be assessed by Treatment Group.
Percentage of Patients with Reduction in Mean Migraine Days (MMD) Baseline to Week 52 - End of Study Percentage of patients with a reduction from Baseline of ≥ 50 percent, ≥ 75 percent and 100% percent in average number of MMD throughout the study will be assessed by Treatment Group.
Suicidality by Columbia-Suicide Severity Rating Scale (C-SSRS) Baseline to Week 52 - End of Study Percentage of Participants with Suicidal Ideation and Behaviors will be assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS) with the suicidal ideation on a 5-point scale, ranging from "wish to be dead" to "activesuidical ideatikon with specific plan and intert" and suicidal behaviors of a 4-point scale ranging from "preparatory acts or behavior" to "actual attempt" in lifetime, past 3 months, and since last visit. The higher total scores indicate more suicidal ideation and /or suicidal behavior.
Development of Anti-Drug Antibodies (ADA) to ABP-450 Baseline to Week 52 - End of Study Percentage of patients developing Anti-Drug Antibodies to ABP-450 antibodies (binding and if positive, neutralizing) will be assessed.
