Trial of STAHIST in Seasonal Allergic Rhinitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01293201
Recruitment Status : Completed
First Posted : February 10, 2011
Last Update Posted : September 2, 2011
Information provided by (Responsible Party):
Magna Pharmaceuticals, Inc.

Brief Summary:
The overall development plan is to show that the combination of tried-and-proven decongestant/antihistamine ingredients (pseudoephedrine hydrochloride and chlorpheniramine maleate), plus a very small amount of belladonna alkaloids (.24 mg atropine sulfate) is a comprehensive, safe and effective B.I.D. drug treatment regimen, indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and children 12 years of age and older. Treated symptoms include nasal congestion, sneezing, rhinorrhea, itchy nose, itchy/watery eyes, and post nasal drip syndrome [reduction in tickly cough (acute or chronic), mucus in the back of the throat, sore throat, and hoarseness]. Considering the favorable safety and efficacy results of Phase 1 and Phase 2, the purpose of Phase 3 is to assess and compare the safety and efficacy of the study drug in a larger group comparatively with a placebo control group. Objectives: A) To report and compare total symptom scores (TSS) by SAR subjects rating the efficacy of STAHIST vs. placebo in relieving nasal congestion, rhinorrhea, nasal itching, sneezing, and post-nasal drip over the two-week study period. B) Report any side effects or adverse drug reactions and rate the severity of any incident. C) Compare and report each symptom score, total nasal symptom scores (TNSS), and post-nasal drip symptom scores (PND-S) between the two study arms.

Seasonal Allergic Rhinitis Drug: STAHIST Drug: Placebo Phase 3

Detailed Description:

Phase 3 clinical trial will be conducted in conformance with Good Clinical Practices and is a multi-center, double-blind, randomized, placebo-controlled, parallel-group study evaluating the safety and efficacy of STAHIST (IMP) in 300 adult and adolescent subjects 12-60 years of age, of either sex or any race with a minimum 2-year history of seasonal allergic rhinitis (SAR) and a baseline minimum total symptom score (TSS) of not less than 8 on the S5 Subject Diary. Subjects will be treated twice daily with IMP or placebo for a period of two weeks. Subjects will visit the study site for at least 4 visits: screening, randomization/study inception, end-of-week one, final visit, and unscheduled visits as appropriate.

Run In (washout period): Subjects will be required to stop using oral nasal decongestants or first generation antihistamines for 48 hours, second generation antihistamines and Singulair for seven days, systemic corticosteroids for 30 days, and nasal or ocular corticosteroid medications for two weeks. Use of these drugs will also not be allowed during the study.

The first dose will be administered at the study site and subjects will be monitored on-site for one hour following dosing. There will be 24-hour on-call telephone access between physician/office staff and study subjects.

A Study Flow Chart will be used to facilitate trial management, record completed tasks as well as document their time of completion (See Study Flow Chart and Source Documents-Appendix D).

Safety evaluations will include monitoring of subject-reported AEs, measurement of vital signs, and assessment of safety laboratory data. Qualified independent, non-study administration individuals will be selected prior to the start of treatment for the purpose of safety monitoring.

300 subjects will be randomized. Assuming a screen failure test rate of approximately 33%, approximately 450 subjects will be screened.

At the conclusion of the study, the CSR will be prepared by the Sponsor, reviewed and approved by the Principal/Coordinator Investigator before submission.
