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.

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.
| Study Type : | Interventional (Clinical Trial) |
| Estimated Enrollment : | 690 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Intervention Model Description: | Approximately 690 patients will be randomized in a 1:1 ratio and receive 1 of the following treatments: ABP-450 Low Dose or ABP-450 High Dose via intramuscular injection into pre-specified areas of the head and neck. |
| Masking: | Triple (Participant, Investigator, Outcomes Assessor) |
| Masking Description: | The investigator, study nurse/other study personnel, and patients will be blinded to the treatment group. An appropriately trained person will reconstitute investigational product, fill masked-labeled syringes and provide them to the investigator, but will not perform any assessments with the patient. |

Primary Outcome Measures :
- Incidence of Treatment Emergent Adverse Events [ Time Frame: 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 [ Time Frame: Baseline to Week 48 - End of Treatment Period ]The primary efficacy endpoint will be the change in mean Monthly Migraine Days (MMD) from Baseline to Weeks 48.
Secondary Outcome Measures :
- Percentage of Patients with Reduction in Mean Migraine Days (MMD) [ Time Frame: 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 will be assessed by Treatment Group.
- Mean change in Monthly Migraine Days (MMD) requiring medications for acute treatment of migraine or headaches [ Time Frame: 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 [ Time Frame: 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 [ Time Frame: Baseline to Week 52 - End of Study ]Overall mean change from Baseline in monthly headache days will be assessed by Treatment Group.
- Suicidality by Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: 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 [ Time Frame: 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.
Other Outcome Measures:
- Mean change of Migraine-Specific-Quality of Life (MSQ) Domains [ Time Frame: Through study completion, an average of 12 months ]The Mean Change in Migraine-Specific-Quality of Life (MSQ), a14-item assessment, with each item rated on a 6-point scale (ranging from "none of the time" to "all of the time") with higher scores indicating better quality of life will be assessed by Treatment Group.
- Mean Change in Patient Global Impression of Change (PGI-C) Score [ Time Frame: Baseline to Week 52 - End of Study ]The Mean change in the subject's assessment of the change in clinical status since the start of treatment measured by the Patients' Global Impression of Change (PGI-C) Scale with 1-item scale ranging from "much better"k to "much worse" with the higher score indicating worsening of symptoms will be assessed by Treatment Group.
- Mean Change in Patient Global Impression of Severity (PGI-S) Score [ Time Frame: Baseline to Week 52 - End of Study ]The Mean change in the subject's assessment of the severity of their condition since the start of treatment measured by the Patients' Global Impression of Severity (PGI-S) Scale with 1-item scale ranging from "normal" to "severely ill" with the higher score indicaating greater severity in illness will be assessed by Treatment Group.
- Mean Change in Migraine Disability Assessment Score (MIDAS) Total Score [ Time Frame: Baseline to Week 52 - End of Study ]The Mean Change in the Migraine Disability Assessment Scale (MIDAS) between Baseline and End of Treatment assessed by Treatment Group. MIDAS is a 5-item self-administered questionnaire. The 5 items sum to a total MIDAS score of 0 to 155. A higher score indicates greater headache-related disability (worse score).
- Percentage of Patients with Reduction in Migraine Physical Function Impact Diary (MPFID) [ Time Frame: Baseline to Week 52 - End of Study ]Percentage of patients with a reduction from Baseline in the impact on Migraine Physical Function Impact Diary (MPFID) will be assessed by Treatment Group with an 8-item scale ranging from "without difficulty" to "extremely difficult". The higher the score represents the highest level of impact.
- Percentage of Patients with Reduction in the Physical Impairment Domaine Score of the Migraine Physical Function Impact Diary (MPFID) [ Time Frame: Baseline to Week 52 - End of Study ]Percentage of patients with a reduction from Baseline on Physical Impairment Domain Score measured by Migraine Physical Function Impact Diary (MPFID) assessed by Treatment Group with a 5-item scale ranging from "none of the time" to "all of the time" or :without any difficulty" to extreemely difficult". The higher the score represents the highest level of impat
