About
Evaluate erenumab- aooe efficacy as a therapeutic approach, for the management of painful chronic temporomandibular disorders (TMD).
The study will be a randomized, double blind, placebo-controlled trial comparing erenumab-aooe vs Placebo.
A total of 60 patients (30 per each arm) aged 18-65 years old of either sex, and any race or ethnicity presenting chronic temporomandibular disorders (TMD), (meeting the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications of chronic TMD (myalgia +/- arthralgia) will be randomly assigned in a 1:1 parallel, double-blind clinical trial, to receive either erenumab-aooe or placebo. Participants will attend 6 clinic visits (Visit 0-Visit 5) over a period of 21 weeks (20 +/- 1 weeks). Changes in pain intensity and other pain outcomes related to TMD will be assessed. Blood samples will be collected, and participants will need to keep a daily symptom diary and answer some other questionnaires.
Full description
Chronic TMD is a considerable burden and affects significantly the quality of life of the sufferer. For some patients, TMD has a tendency to remit or improve pain symptomatology over time but for others, TMD have the potential to become chronic and to lead to persistent dysfunction.
Different classes of medications from anti-inflammatories, muscle relaxants, anxiolytics, antidepressants, anticonvulsants and a β-blocker have indicated to be beneficial for some patients as well as in clinical studies, but tolerability and side effects may be present for some patients. Furthermore, the indications of these drugs are for other disorders, so it is unclear their mechanism of action in TMD pathophysiology. Currently there is no medication specifically indicated for the management of TMD based on its molecular pathophysiology. However, there is evidence showing that CGRP has a role in TMD pathophysiology. CGRP is a key molecule in migraine pathophysiology. Erenumab-aooe is the first antibody therapeutic targeting the CGRP and has shown efficacy, to be well tolerated and with a safety profile similar to placebo for the prevention of migraine. The scientific premise for this study is that inhibiting CGRP in chronic TMD will decrease pain, pain related outcomes and improve TMJ biomechanics (function) in a safe and well tolerated manner for this patient population.
Potential participants will be pre-screened at the Brotman Facial Pain clinic and the Oral and Maxillofacial Surgery Clinic both at the University of Maryland, School of Dentistry or by telephone; those willing to participate will be scheduled for a screening and baseline visit (Visit 0). During this visit potential participants will be evaluated for eligibility (meeting the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications) of chronic TMD (myalgia +/- arthralgia) and written informed consent will be obtained.
The screening and baseline procedures include medical history review, clinical examinations, tests and administration of questionnaires. After screening, eligible participants will start Visit 0/Day 0 which is the start of the baseline period with a duration of 28 days/4 weeks. Instructions will be given for the completion of a Daily Symptom Diary (DSD) and other questionnaires at home or online. Participants who show 80% compliance with the DSD and who meet the pain score (inclusion criteria) during the baseline period, will be randomly assigned to one of two groups either the investigational drug or placebo and will be scheduled for Visit 1. Visit 1 can occur within 7 days/1 week after the baseline period (+/- 7 days).
The study drug is erenumab-aooe 70mg, SC injection. Participants will attend 6 clinic visits (Visit 0-Visit 5) over a period of 21 weeks (20 +/- 1 weeks) or 140 +/- 7 days. After randomization and on Visit 1 (Week 4/Day 28), the participant will receive the drug or placebo. This same treatment will be administered once a month for 3 months (3 cycles/12 weeks). It will be administered on Visit 1/Day 28/Week 4; Visit 2/Day 56/Week 8; and Visit 3/Day 84/week 12. On Visit 0 (baseline) and on Visit 1, Visit 2, Visit 3, Visit 4/Day 112/Week 16 and visit 5/Day 140/Week 20, visits will include review of compliance with inclusion criteria, medical history review, review and collection of any adverse event, clinical examinations, questionnaires, tests, blood sample collection on Baseline/Visit 0 and Visit 4; and instruction to complete the DSD and questionnaires.

Inclusion criteria
-
In order to be eligible to participate in this study, an individual must meet all of the following criteria:
-
Provide signed and dated informed consent form
-
Is between 18 and 65 years of age (inclusive; male or female and any race or ethnicity)
-
Meets diagnostic criteria for TMD: Myalgia with or without arthralgia
• The participant must meet 2 criteria relating: 1) reported pain, ache or tenderness in the face, jaw/mandible, pre-auricular area, inside the ear or temple that it is modified by TMJ biomechanics. 2) finding(s) of TMD myalgia according to the classification DC/TMD criteria.
-
Has experienced facial pain and/or pain with TMJ biomechanics for the last 3 months episodically or unremitting
-
Has experienced facial pain for at least 10 days of the last 30 days prior to Baseline Visit (Visit 0)
-
Prior to randomization, has been compliant 80% with the entries in the Daily Symptom Diary within the baseline period and reported an average pain level ≥30 on a numerical rating scale (0-100) in the DSD, or has experienced a pain level ≥30 on the same scale for at least 3 days in the week prior to Visit 1.
-
If taking a prescription medication daily for the management of pain (taken for at least 30 days before baseline), agrees to continue the daily use of the medication throughout the study at the same dosage.
-
If taking prescription medication, opioid medication or OTC medications as needed or episodically for the management of TMD pain agrees to discontinue its use prior to the Screening and Baseline Visit.
- Rescue medications will be defined as allowable over-the-counter analgesics used for treatment of TMD pain. In case a patient presents pain during the study, only it is allowed the use of OTC medications as a "rescue" and as described on section 6.6.3: Participants use of short-acting non-prescription analgesics such as NSAIDs, acetaminophen or aspirin during the study, will be recorded and quantified at each visit, and the usage will be classified as either episodic or daily. Episodic use of non-prescription analgesics will be defined as use for no more than 2 consecutive days and for no more than 18 days from baseline to visit 4.
- This type of analgesics should not be used for more than 2 days a week prior to Baseline and a week prior to visit 4, when the exploratory outcome is assessed (cytokine release assay).
-
If taking OTC pain medications daily agrees to continue its daily use at the same dosage throughout the study.
• If a participant is taking an over-the-counter medication daily for management of other type of pain or for prophylaxis of myocardial infarction or stroke, the participant will be encouraged to continue the same usage of that medication throughout the study.
