A Comparative Bioavailability and Adhesion Performance Study, Comparing a New Scopolamine Transdermal Delivery System Formulation to the Currently Established Reference Transdermal Delivery System in Healthy Adult Participants.

A Randomized, Single-center, Crossover, Comparative Bioavailability and Adhesion Performance Study, Comparing Single Administrations of a New Scopolamine Transdermal Delivery System Formulation to the Currently Established Reference Transdermal Delivery System in Healthy Adult Participants.

In this comparative bioavailability and in vivo skin adhesion study, the impact of minor changes in qualitative composition of polyiso-Butylenes (PIB) from a different supplier and change of the manufacturing line of the micro porous membrane will be tested.

Study Overview

• Status: Completed
• Conditions: Motion Sickness
• Intervention / Treatment: Drug: Reformulated scopolamine patch; Drug: Marketed scopolamine patch

Detailed Description

This study is a randomized, single-center, cross-over, comparative bioavailability and adhesion study, comparing single administrations of a new scopolamine transdermal delivery system formulation to the current established reference transdermal delivery system in healthy adult participants. The study will consist of an ambulant screening day within 21 days prior to the first investigational medicinal product (IMP) administration at study Day 1 and two treatment periods. Each treatment period will consist of 4.5 days (108 hours) of in-house confinement.

Double barrier and periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) are not acceptable means of contraception; A woman who is postmenopausal must have a negative urine pregnancy test at screening but will not need to comply with an acceptable method of contraception. Women are considered post-menopausal and not of child bearing potential if they had 12 months of natural (sp ntaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with known or reported serum FSH levels > 40 mIU/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks before.

• History within the last five years or current evidence of pulmonary, gastrointestinal, hematological, endocrinological, metabolic, autoimmune, neurological, psychiatric or other diseases at screening unless deemed medically insignificant or clinically insignificant as assessed by the Investigator.
• Clinically significant laboratory findings at screening such as anemia (hemoglobin <11.5 g/dL for women and <13.5 g/dL for men), serum potassium <3.5 mmol/L or >5.0 mmol/L, or serum sodium <132 mmol/L or >150 mmol/L.
• Use of any medication within 2 weeks before first scheduled study drug administration or within less than 10 times the elimination half-life of the respective drug (whichever is longer), or is anticipated to require any concomitant medication during that period or at any time throughout the study.
• Any history of asthma, urticaria, or other significant allergic diathesis. Participants with uncomplicated seasonal allergic rhinitis can be accepted if expected allergy season is clearly outside enrolment/ treatment period.
