Outcomes

Primary Outcome Measures

Change of >= 30% reduction in the monthly (28 days) average pain score from baseline to Visit 4, compared to placebo.
Assessment of the efficacy of erenumab-aooe in the proportion of participants that achieve >=30% reduction (Yes/no) in monthly (28 days) average pain score from baseline to Visit 4 (the last monthly treatment cycle), compared to placebo. The daily pain intensity score will be measured on a 11-point (0-10) numeric rating scale (NPRS) and reported in the Daily Symptom Diary (DSD). The monthly mean pain intensity score will be determined from baseline (4 weeks/28 days), for each month during the 12 weeks of treatment.

Secondary Outcome Measures

Efficacy of erenumab-aooe compared to placebo on the reduction in monthly average daily pain score from baseline to the end of 12-week treatment period.
Comparison of erenumab-aooe with placebo in the reduction of pain score from baseline continuously through to the end of 12 weeks (Visit 4).
Change of >= 30% reduction in the monthly (28 days) average pain score compared to placebo from baseline to Visit 5.
Assess the efficacy of erenumab-aooe compared to placebo on the proportion of subjects who achieved a least 30% reduction in the monthly average daily pain score from baseline to Visit 5 (follow-up/final visit).
Change in participant ratings compared to placebo for improving physical function and health related quality of life in patients with trigeminal neuropathic pain measured by the Penn Facial Pain Scale-Revised.
Efficacy of erenumab-aooe compared to placebo in improvement on burden/disability of daily activities related to trigeminal neuropathic pain (e.g. chewing, eating, talking, touching) measured by the Penn Facial Pain Scale-Revised. 12 items. The higher the score the more pain and disability.
Change in Graded Chronic Pain Scale (GCPS) outcomes during erenumab-aooe treatment, after treatment and compared to placebo.
The GCPS includes 7 items and assesses 2 dimensions of pain, pain intensity and pain-related disability. A higher grade means a worse outcome.
Change in the Hospital Anxiety and Depression Scale (HADS). Anxiety and Depression score change during erenumab-aooe treatment, after treatment and compared to placebo.
The HADS evaluates anxiety (7 items) and depression (7 items) with a 14-item instrument assessing symptoms on a 4-point scale rated from 0 "not at all" to 3 "very often indeed". Responses provide separate scores for anxiety and depression. A higher score means a worse outcome.
Change in impression of overall status measured by the Patient Global Impression of Change (PGIC) during erenumab-aooe treatment, after treatment and compared to placebo.
The PGIC measures change in participant's overall status on a scale ranging from 1 (very much improved) to 7 (very much worse).

5. Study Description

Brief Summary
This study is a single center, placebo-controlled, double blind, randomized, phase II pilot to evaluate the efficacy of erenumab-aooe in the management of trigeminal neuropathic pain comparing erenumab-aooe vs Placebo. A total of 40 patients (20 each arm) aged 18-65 years old of either sex, and any race or ethnicity, presenting trigeminal neuropathic pain will be randomly assigned in a 1:1 parallel, double-blind clinical trial, to receive either Erenumab or placebo. Participants will attend 6 clinic visits (Visit 0-Visit 5) over a period of 21 weeks. Changes in pain intensity and other pain related outcomes of trigeminal neuropathic pain will be assessed. Blood samples will be collected, and participants will need to keep a daily symptom diary and answer some other questionnaires.
Detailed Description
TNP are a considerable burden and affects significantly the quality of life of the sufferer. There are medications for their management but while they may work for some patients, may not work for the others; in addition, side effects may be present for some patients with the need to decrease dosage to not optimal levels. Furthermore, the indications of these drugs are for other neuropathic pain disorders and currently there is no medication specifically indicated for the management of TNP based on its molecular pathophysiology. The calcitonin gene-related peptide (CGRP) is a key neuropeptide involved in migraine pathophysiology. There is evidence showing that CGRP has a role in other disorders mediated by the trigeminal system in addition to migraine; CGRP has shown to have a role in orofacial pain such as in TMD and in trigeminal neuropathic pain. Erenumab-aooe is the first antibody therapeutic targeting the CGRP receptor with FDA approval for migraine prevention that is well tolerated and with a good safety profile. Therefore, the scientific premise for this study is that inhibiting the CGRP pathway in trigeminal neuropathic pain will decrease pain and pain related outcomes in a safe and well tolerated manner for this patient population. Potential participants will be pre-screened at the Brotman Facial Pain clinic, at the Oral and Maxillofacial Surgery Clinic both at the University of Maryland, School of Dentistry, at the Pain Medicine Clinic at the University of Maryland, School of Medicine 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 for trigeminal neuropathic pain (subjects with diagnosis based on the International classification of headache disorders ICHD-3 and International classification of Orofacial Pains ICOP of idiopathic trigeminal neuralgia with concomitant continuous pain, painful posttraumatic trigeminal neuropathy or idiopathic painful trigeminal neuropathy) and written informed consent will be obtained. The screening and baseline procedures include medical history review, clinical examinations, tests and administration of questionnaires. Instructions will be given for the completion of a Daily Symptom Diary (DSD) and other questionnaires at home or online. Participants who show compliance with 80 % completion of the DSD and who meet the pain score (inclusion criteria) for 4 weeks/28 days during the baseline period from Visit 0, will be randomly assigned to one of two groups either the investigational drug or placebo and will be scheduled for Visit 1. The study drug is Erenumab 140 mg, SC injection. Participants will attend 6 clinic visits (Visit 0-Visit 5). After randomization and on Visit 1, the participant will receive the drug or placebo. This same treatment will be administered once a month for 3 months (3 cycles/12weeks).
