      <textblock>
        The goal of this clinical trial is to evaluate the safety, tolerability and pharmacokinetics&#xD;
        (PK) profiles* of MDI-1228_mesylate Ophthalmic Solution in patients with allergic&#xD;
        conjunctivitis and healthy adult participants. This trial also aims to study the preliminary&#xD;
        efficacy of MDI-1228_mesylate Ophthalmic Solution in patients with allergic conjunctivitis.&#xD;
  &#xD;
        Participants will receive either of the following treatment:&#xD;
  &#xD;
          -  MDI-1228_mesylate Ophthalmic Solution, or&#xD;
  &#xD;
          -  Placebo**&#xD;
  &#xD;
        Researchers will observe any changes in heath (if any) in participants receiving the study&#xD;
        treatment to evaluate the safety of study drug. Researchers will also focus on any changes in&#xD;
        symptoms of patients with allergic conjunctivitis to evaluate the efficacy of study drug.&#xD;
  &#xD;
        Note:&#xD;
  &#xD;
        *PK profiles: how the drug interacts with the body.&#xD;
  &#xD;
        **placebo: a harmless substance that contains no active agents.&#xD;

  The goal of this clinical trial is to evaluate the safety, tolerability and pharmacokinetics
        (PK) profiles* of MDI-1228_mesylate Ophthalmic Solution in patients with allergic
        conjunctivitis and healthy adult participants. This trial also aims to study the preliminary
        efficacy of MDI-1228_mesylate Ophthalmic Solution in patients with allergic conjunctivitis.
  
        Participants will receive either of the following treatment:
  
          -  MDI-1228_mesylate Ophthalmic Solution, or
  
          -  Placebo**
  
        Researchers will observe any changes in heath (if any) in participants receiving the study
        treatment to evaluate the safety of study drug. Researchers will also focus on any changes in
        symptoms of patients with allergic conjunctivitis to evaluate the efficacy of study drug.
  
        Note:
  
        *PK profiles: how the drug interacts with the body.
  
        **placebo: a harmless substance that contains no active agents.
