Clinical Trial of STAHIST in Seasonal Allergic Rhinitis Patients

Overview

MAGNA intends to show that the combination of pseudoephedrine, chlorpheniramine, plus a small amount of belladonna alkaloid is a comprehensive, safe and effective twice daily (BID) drug treatment for seasonal allergic rhinitis (SAR) patients with post-nasal drip (PND). The phase 1 single-dose trial will consist of 21 subjects: 1) to gather pharmacodynamic measurements and blood levels of active ingredients over 12 hours; 2) To report subjective scores by subjects rating efficacy of single dose of STAHIST; 3) To report any side effects or adverse drug reactions and rate the severity of incidence.

No procedure will be performed until Informed Consent has been obtained. Inclusion and exclusion criteria will be verified. 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 not be allowed during the study. Blood samples will be drawn at specific time points: baseline fasting blood draw just before 7AM, then at 9 AM, 11AM, 3PM, and 7PM. A single oral dose of STAHIST will be administered at 7AM. During the study a diary of the five study symptoms (S5 Diary) will be scored hourly over the 12-hour period as follows: 0 none, 1 mild, 2 moderate, 3 severe. The S5 symptoms are 1. Nasal Congestion (Stuffiness); 2. Sneezing; 3. Rhinorrhea (runny nose); 4. Nasal Itching; 5. Post-nasal drip. Post nasal drip is defined for the patient as "you can feel accumulated mucus dripping down the back of your throat from your sinuses, also possibly including a tickly cough or sore throat due to this sensation of mucus." Side effects or adverse drug reactions will be scored if they occur and hourly as 1 mild, 2 moderate, and 3 severe. Any adverse events will be recorded. Any subject who is not able or who is unwilling to continue keeping a diary or participate in blood draws will be permitted to withdraw from the study. Safety will be assured by the frequent visible assessment and questioning of subjects as well as monitoring of subjects' vital signs by Dr. Pollard and his nursing staff. Subjects will remain in the clinic during the 12-hour dosage interval. Thereafter, Dr. Pollard and selected staff will be on call 24 hours to answer any subject phone calls.
