Study summary

Determine the efficacy, in terms of time to nausea (inclination to vomit), of DPI-386 Nasal Gel as compared to the current standard of care (TDS) and placebo nasal gel. • Describe the pharmacokinetics (PK) of a multi-dose schedule of DPI-386 Nasal Gel (0.2 mg twice a day for six consecutive days) as compared to the current standard of care (TDS). Determine the safety of a multi-dose schedule of DPI-386 Nasal Gel with an emphasis on cognitive adverse events as compared to the current standard of care (TDS) and placebo nasal gel. Determine how alertness is affected by administration of DPI-386 Nasal Gel, as compared to the current standard of care (TDS) and placebo nasal gel.

Read the detailed description

Each subject eligible for the study on Day 0 will be assigned a subject number (starting with 101 for male subjects and 201 for female subjects) in consecutive order which will randomize the subject to one of the three study arms: double-blind DPI-386 Nasal Gel; double-blind placebo nasal gel; or Transderm Scop® (TDS). The subject number will link the nasal gel (active or placebo) treatment arms (double-blind) to a multi digit random number (study drug kit number) different from the subject number. The nasal gel vials, contained in the study drug kit, will be labelled with the same study drug kit number. Each 0.12 gram of the gel contains 0.2 mg of scopolamine HBr as the active ingredient along with the excipients sodium citrate, citric acid, sodium metabisulfite, glycerin, benzalkonium chloride, polyvinyl alcohol, and purified water.

  3. Male or female, aged 18 to 59 (inclusive).
  4. Active duty military, reserves on active status, or dependents covered by Tricare health insurance. All potential subjects must be able to provide a current military or DoD dependent ID to be viewed by the PI or qualified designee prior to signing the ICD.
  5. At least minimally susceptible to provocative motion as evidenced by a minimum score of 3.0 on the Motion Sickness Susceptibility Questionnaire (MSSQ).
  6. In good general health as evidenced by medical history with no recent history or current diagnosis of clinical problems that would affect rotation in a vestibular study (e.g., vestibular pathology, seizure disorder, sinus congestion), as assessed by the PI or qualified designee.
  7. Laboratory test results that are determined by the PI or qualified designee to be normal or - if slightly out of the normal range - determined to be not . The following laboratory tests will be performed:

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
