An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment. A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization.

Blood samples were collected to assess clinical significant shifts in laboratory parameters. "Normal to High" means at baseline the value is Normal and maximum post baseline value is High.

SBP (Systolic blood Pressure) and DBP (Diastolic Blood Pressure) measured in mmHg and Heart rates measured in beats per minute.

Dysphagia Days (DD) was assessed using a modified daily symptom diary (mDSD). The DD was evaluated over the prior 14-day period using the mDSD, which includes 6 primary questions. These questions assess solid food consumption that day (Q1), experience with trouble swallowing (Q2), food going down slowly (Q3), food getting stuck in the throat or chest (Q4), actions taken by participants to obtain relief (Q5), and any pain associated with swallowing (Q6). The number of DD was normalized by calculating the number of diary days with a "yes" to any or all of Q2, Q3, and Q4 in the 14-day period prior to a visit, dividing by the number of measurable diary days in the 14-day period, and then multiplying by the length of the period (14). A measurable diary day for DD is defined as a diary day for which Questions 2 to 4 are answered. Mean DD ranges from 0 to 14 for the 14-day period.

Blood samples were collected to assess esophageal eosinophil count.
