Study Endpoints

Primary Endpoints

Area Under Curve (AUC) of the Total Nasal Symptoms Score (TNSS-3)
From 0 hour to 6 hours at Day 4

TNSS-3=composite score calculated as sum of rhinorrhea, sneezing, and nasal itching scores (TNSS-3: scale of each symptom is scored from 0 to 3), where 0 indicates no symptoms, a score of 1 for mild symptoms that are easily tolerated, 2 for awareness of symptoms which are bothersome but tolerable and 3 is reserved for severe symptoms that are hard to tolerate and interfere with daily activity. Individual scores were collected in e-diary. AUC of TNSS from time of the first observation to time of the last observation (AUC \[0-6 hr\]) was calculated by using the linear trapezoid method. Trapezoidal rule involves dividing the area into a number of strips of equal width. Then, approximating the area of each strip by the area of the trapezium formed when a chord replaces upper end. Sum of these approximations gives final numerical result of area under the curve. AUC range: Arm A=0.0-43.5; Arm B=2.1-39.9.

Frequently asked questions about Fexofenadine New Formulation

What is Fexofenadine New Formulation?

Fexofenadine New Formulation is an investigational small molecule developed by Sanofi (ticker SNY) for respiratory and allergic conditions. It is being studied in asthma, atopic dermatitis, perennial rhinitis, and seasonal allergic rhinitis. The program is in Phase 3 development, with completed randomized, double-blind trials enrolling about 3,200 participants in total.

What is Fexofenadine New Formulation used for?

Fexofenadine New Formulation is being studied for asthma, atopic dermatitis, perennial rhinitis, seasonal rhinitis, and seasonal allergic rhinitis. These are the conditions listed across its clinical program. It remains investigational for these uses and is not described as approved for them.

What does Fexofenadine New Formulation target?

Fexofenadine New Formulation targets HRH1, the histamine H1 receptor, and acts as an antagonist at that receptor. Blocking HRH1 is the mechanism studied across its allergy and respiratory indications. The asset is a small molecule in Sanofi's respiratory pipeline.

Who makes Fexofenadine New Formulation?

Sanofi, which trades under the ticker SNY, is the developer of Fexofenadine New Formulation. Sanofi is listed as the sponsor of the clinical program covering asthma, atopic dermatitis, and rhinitis indications.

What phase is Fexofenadine New Formulation in?

Fexofenadine New Formulation is in Phase 3 development. Three trials are recorded as completed and none are currently active. The program includes Phase 3 work in seasonal allergic rhinitis and Phase 2 studies in pediatric atopic dermatitis and perennial allergic rhinitis.

What clinical trials is Fexofenadine New Formulation in?

Completed trials include NCT05692154, a Phase 3 placebo-controlled study of 2-day pre-treatment in seasonal allergic rhinitis in Canada, and NCT01306721, a Phase 3 study in seasonal rhinitis in Japan. Pediatric Phase 2 studies NCT01244230 in atopic dermatitis and NCT01244217 in perennial allergic rhinitis also completed in Japan.

Is Fexofenadine New Formulation the same as Allegra?

Fexofenadine New Formulation is also known as fexofenadine HCl new formulation tablet and appears in trial records under fexofenadine/Allegra and fexofenadine HCL (M016455). Fexofenadine is the active ingredient associated with the Allegra name, so searches for these terms refer to the same fexofenadine program.
