Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Mirabegron

Placebo

Arm Description

Patients will receive 50 mg of oral Mirabegron daily for 4 weeks and then switch to placebo by mouth daily for an additional 4 weeks.

Patients will receive placebo by mouth daily for 4 weeks and then switch to oral Mirabegron 50 mg daily for an additional 4 weeks.

Outcomes

Primary Outcome Measures

Changes in lower esophageal sphincter pressures
Evaluation of changes in lower esophageal sphincter pressures using high resolution manometry

Secondary Outcome Measures

Eckardt Achalasia Score (EAS)
Patients will complete the Eckardt Achalasia score which is a simple written scale evaluating dysphagia, regurgitation, retrosternal pain and weight loss. Patients report their symptoms from a 0 to 3. Weight loss (0-none, 1: < 5 kg, 2: 5-10 kg, 3: > 10 kg), Dysphagia (0-none, 1-occasional, 2-daily, 3-each meal), Retrosternal pain (0-none, 1-occasional, 2-daily, 3-each meal), Regurgitation (0-none, 1-occasional, 2-daily, 3-each meal). The value for each of the 4 categories is added together to give the EAS. This EAS will be reported for each time point below. A higher score is consistent with worse achalasia and worse outcomes. A lower score is consistent with less severe achalasia and better outcomes. The total range is 0 (no symptoms) to 12 (severe symptoms). There are no subscales.

5. Study Description

Brief Summary
This study evaluates whether a medication called mirabegron is better than placebo (sugar pill) in helping patients with achalasia swallow better. Each patient will receive either mirabegron or the placebo for 4 weeks followed by the opposite medication. Each patient will complete several surveys and undergo several tests to determine if the mirabegron is helping reduce the pressures in the esophagus (swallowing tube).
Detailed Description
Achalasia is characterized by incomplete or absent relaxation of the lower esophageal sphincter (LES) and loss of esophageal peristalsis which leads to dysphagia. Standard of care for achalasia includes endoscopic management (dilation and injection of injection of botulinum toxin) and surgery, however both of these options carry procedural risks, may lose efficacy over time and many patients are not appropriate candidates for these treatment options. Unfortunately, there are limited oral medications for patients with achalasia. Mirabegron is an oral beta-3 agonist currently FDA approved for overactive bladder that works by relaxing the bladder muscles. Beta-3 receptors have also been identified in the LES with stimulation leading to LES relaxation in preclinical studies. Through a proof of concept pilot study, the investigators aim to evaluate the effect of mirabegron in patients with achalasia via high resolution manometry and a validated dysphagia scale.

Eckardt Achalasia Score (EAS)
Description
Patients will complete the Eckardt Achalasia score which is a simple written scale evaluating dysphagia, regurgitation, retrosternal pain and weight loss. Patients report their symptoms from a 0 to 3. Weight loss (0-none, 1: < 5 kg, 2: 5-10 kg, 3: > 10 kg), Dysphagia (0-none, 1-occasional, 2-daily, 3-each meal), Retrosternal pain (0-none, 1-occasional, 2-daily, 3-each meal), Regurgitation (0-none, 1-occasional, 2-daily, 3-each meal). The value for each of the 4 categories is added together to give the EAS. This EAS will be reported for each time point below. A higher score is consistent with worse achalasia and worse outcomes. A lower score is consistent with less severe achalasia and better outcomes. The total range is 0 (no symptoms) to 12 (severe symptoms). There are no subscales.
Time Frame
Patients will complete the EAS on study day -14, 0, 7, 28, 42, 49, 70, 84. We will evaluate changes in patient's EAS between day 0 and all of these time points.
