AllerPops Reduce Nasal Symptoms in Adult Volunteers With Allergic Rhinitis

A Phase II, Randomized, Double-blind, Controlled, Single-centre 21-day Study to Investigate the Efficacy of AllerPops to Reduce Nasal Symptoms in Adult Volunteers With Seasonal/Year-long Nasal Allergies

The goal of this clinical trial is to test AllerPops' effectiveness in people who suffer from allergic rhinitis. The main question[s]it aims to answer are:

1. To assess the effectiveness of AllerPops on relieving nasal symptoms compared to the control group in volunteers with seasonal/year-long allergies during the first 7 days of the 21-day intervention period.
2. To evaluate the safety of AllerPops administration in volunteers with seasonal/year-long allergies during a 21-day intervention period.

Up to 30 days between Screening (V1) and Baseline (V2), and a 21-day intervention period, with dosing occurring every other day for a minimum of 3 doses, and thereafter until the participant is satisfied with the relief of the nasal allergy symptoms. The suitable season for the trial will be determined based on the seasonal variation measures.

Researchers will compare slow and fast consuming groups to see if the way of use impact the effectiveness.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Investigation; Dosing Instructions; Brush teeth with water (no toothpaste).; Scrub tongue with warm, wet, washcloth from the back to the front until most of the white/yellow biofilm on the tongue is gone.; Gargle and swish hot (optimal 120°F) water for 10-20 seconds. Spit out and repeat gargling over the next 5 minutes. The tongue should be red and without any biofilm. If it is not, repeat Step 2, and gargle once more.; Self-administer one lozenge. Let the lozenge slowly melt in the mouth. Do not chew or swallow whole. This may take up to 60 minutes. Discard if it is not fully dissolved after 60 minutes.; Wash the washcloth to be ready before next use.	Dietary supplement: AllerPops; Take AllerPops once every other day, as instructed, for a minimum of 3 doses. After each dose, wait at least 30 minutes before eating your next meal. After the 3rd dose, you may continue every other day until you are satisfied with the symptom relief up to and including Day 13.
Active Comparator: Control; Dosing Instructions; Microwave: heat the product in 5 second increments until soft. (Caution: more than 10 seconds of microwaving the product may cause it to burn).; Cut: cut the product into smaller pieces; Swallow: swallow without chewing the pieces with warm water while they are still warm. It can be swallowed over time or at once.	Dietary supplement: AllerPops; Take AllerPops once every other day, as instructed, for a minimum of 3 doses. After each dose, wait at least 30 minutes before eating your next meal. After the 3rd dose, you may continue every other day until you are satisfied with the symptom relief up to and including Day 13.

To evaluate the safety of AllerPops administration in volunteers with seasonal/year-long allergies during a 21-day intervention period. a. Safety will be assessed by collecting vital signs (temperature, blood pressure, heart rate), the emergence of adverse events, and clinical chemistry (complete blood count, CBC [Includes: White Blood Cell Count (WBC), Red Blood Cell Count (RBC), Hemoglobin (HB), Hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), Platelet Count] and a comprehensive safety panel: Aspartate aminotransferase (AST), Sodium, Potassium, Chloride, Serum creatinine, Alanine Amino Transferase (ALT), Alkaline Phosphatase (ALP), Bilirubin Total and Gamma Glutamyl Transpeptidase (GGT)), and PI assessment. This assessment will be conducted at the baseline D1, D7, D14 and D21.	21 days
Changes in participants' oral microbiomes using 16S amplicon metagenomic sequencing.	The exploratory study of the effect of AllerPops in oral microbial presentation/microbiota through Amplicon Metagenomics Sequencing test which is a rRNA gene (V3-V4 region) sequencing method in saliva. The evaluation will be measured at D1, D7 and D21.	21 days
