Study arms

  • Experimental
    DPK-060 2% ear drops

    DPK-060 2% ear drops, 0.3 mL/pipette, 3 times daily for 7 or 10 days (as applicable).

    Drug: DPK-060

  • Placebo comparator
    Placebo for DPK-060 ear drops

    Placebo for DPK-060 ear drops, 0.3 mL/pipette, 3 times daily for 7 or 10 days (as applicable).

    Drug: Placebo for DPK-060 ear drops

Interventions

  • DrugDPK-060

    DPK-060 2% ear drops were administered as 3 applications per day into the outer ear by use of a single-dose pipette (0.3 mL/pipette) for 7 days. In case clinical symptoms remained after 7 days of treatment, the treatment period was extended by another 3 days with 3 applications per day.

  • DrugPlacebo for DPK-060 ear drops

    Placebo for DPK-060 ear drops were administered as 3 applications per day into the outer ear by use of a single-dose pipette (0.3 mL/pipette) for 7 days. In case clinical symptoms remained after 7 days of treatment, the treatment period was extended by another 3 days with 3 applications per day.

What researchers measure

Primary outcomes

  1. Adverse Events (AEs)

    AEs were collected by a non-leading question such as "have you experienced any new health problems or worsening of existing conditions" as well as reporting events directly observed or spontaneously volunteered by patients. All AEs including but not limited to events reported by the patient, or reported in answer to an open question by the Investigator or member of the study team were recorded as an AE including the following information: Diagnosis; Start date (and time, if relevant), Stop date (and time, if relevant) or resolution; Severity; Action taken; Causality; Seriousness; Outcome.

    Time frame: AEs occurring during the treatment period were collected on day 8 or 11, as applicable. Four weeks after the last dose of investigational medicinal product (IMP), previously reported AEs were followed up and assessed as "recovered" or "not recovered".

Adverse events

Collected over AEs occurring during the treatment period were collected on day 8 or 11, as applicable. Four weeks after the last dose of investigational product, previously reported AEs were followed up and assessed as "recovered" or "not recovered". Non-serious events are listed at a 5% frequency threshold.
