• Known or suspected intolerance or hypersensitivity to any of the study medications, excipients, investigational device material, or to medications of similar chemical classes, any history of drug hypersensitivity, asthma, urticaria, or other significant allergic diathesis, known or suspected contraindications, including history of allergy, or photosensitivity to study medication/s
• Participation in another clinical study (including cosmetic studies) or receipt of an investigational drug within 30 days of screening or 5 half-lives of the other clinical studies investigational drug, whichever is longer, Previously enrolled in the current study
• Current smoker or smoked or used nicotine containing products within 5 years of screening, history (within 5 years prior to study start) or evidence of illicit drug abuse or if the investigator suspects current drug use with drug classes that include but are not limited to barbiturates, amphetamines, benzodiazepines, cocaine, opiates, cannabis or any other illicit drugs (verified by urine drug screening or other reliable evidence), history or evidence of current alcohol abuse or if participant reports a regular average alcohol consumption exceeding 18 g (women) or 35 g (men) of pure alcohol per day, i.e. 1 drink/day for women or 2 drinks/day for men (1 drink = 150 mL of wine or 360 mL of beer or 45 mL of hard liquor) within 6 months of screening
• Non-acceptance of standardized food and beverages throughout each confined study period, Ingestion of food containing poppy seeds (muffins, bagels, cakes, etc) within 24 hours of admission to the study site
• Persons directly or indirectly involved in the execution of this protocol, including employees of the contract research organization (CRO) and persons related to them, an employee of the sponsor or the study site or members of their immediate family
• On nasal examination, the presence of any superficial or moderate nasal mucosal erosion, nasal mucosal ulceration, or nasal septum perforation (Grade 1B - 4) during the screening visit or Day -1, Participants with difficulty in using the nasal spray applicator, "Vulnerable" individual (as defined by the Institutional Review Board (IRB) e.g. incarcerated person), any condition not identified in the protocol that in the opinion of the investigator would confound the evaluation and interpretation of the study data or may put the participant at risk, no consumption of alcohol-containing products within 24 hours before confinement and throughout confined study period

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Carbomer 980; Participants will be administered test product (nasal spray) containing 0.5% carbomer 980, 4 times per day (i.e. 3 actuations per nostril per dose; each actuation will be 140 mcL, equivalent to 140 mg).	Drug: Carbomer 980; Test product containing 0.5% carbomer 980 gel
PLACEBO_COMPARATOR: Placebo; Participants will be administered reference product (nasal spray) containing vehicle without carbomer 980, 4 times per day (i.e. 3 actuations per nostril per dose; each actuation will be 140 mcL, equivalent to 140 mg).	Other: Placebo; Reference product containing vehicle without 0.5% carbomer 980 gel

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidences of nasal mucosal changes of ≥ Grade 1B	The investigators will perform a thorough examination using nasal mucosal grading scale: Grade 0 = No abnormal findings, Grade 1A = focal nasal mucosal irritation (inflammation, erythema or hyperemia), Grade 1B = superficial nasal mucosal erosion, Grade 2 = moderate nasal mucosal erosion	Baseline to Day 8
Incidence of moderate or severe mucosal bleeding	The investigators will perform a thorough examination using mucosal bleeding scale: 0 = None, 1 = Mild, 2 = Moderate, 3 = Severe	Baseline to Day 8
Incidence of moderate or severe crusting of mucosa	The investigators will perform a thorough examination using crusting of mucosa scale: 0 = None, 1 = Mild, 2 = Moderate, 3 = Severe	Baseline to Day 8

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse events	All adverse events reported by participants will be recorded.	Baseline to Day 8
Change from baseline in Blood pressure	Systolic and diastolic BP will be measured three times after the participant has been sitting for 5 minutes using an automated validated device, e.g. OMRON, with an appropriately sized cuff. The repeat sitting measurements will be made at 1-2 minute intervals and the mean/average of the three measurements will be recorded.	Baseline to Day 8
Change from baseline in pulse	Pulse will be measured three times after the participant has been sitting for 5 minutes using an automated validated device, e.g. OMRON, with an appropriately sized cuff. The repeat sitting measurements will be made at 1-2 minute intervals and the mean/average of the three measurements will be recorded.	Baseline to Day 8
Change from baseline in respiration rate	The rate will be measured by counting the number of breaths for one minute (counting how many times the chest rises).	Baseline to Day 8
Change from baseline in oral body temperature	Oral body temperature will be measured. Reference range (Oral body temperature between 35.0 º Celsius (C) and 37.5 ºC)	Baseline to Day 8
Change from baseline in Hematology	Hemoglobin (Hb), hematocrit (Ht), red blood cell (RBC) count (including mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), white blood cell (WBC) count with differential and platelet count will be measured.	Baseline to Day 8
Change from baseline in clinical Chemistry	Electrolytes (sodium, potassium, chloride, calcium, phosphorous), substrates (Blood Urea Nitrogen [BUN], creatinine, total bilirubin, total protein, albumin, uric acid, and C-reactive protein), and enzymes (aspartate amino transferase [AST], alanine amino transferase [ALT], alkaline phosphatase (ALP), gamma glutamyl transferase [GGT], creatine kinase [CK]) will be measured.	Baseline to Day 8
Change from baseline in virus Serology	Serology will be performed only for Hepatitis B Surface Antigen (HBs Ag), Hepatitis B core antibody [anti-HBc] (Immunoglobulin G [IgG] + Immunoglobulin M [IgM]), anti-HCV Ab [Hepatitis C Virus antibody], Human Immunodeficiency Virus [HIV] 1 and HIV 2 antibodies.	Baseline to Day 8
Change from baseline in urinalysis	Specific gravity, nitrite, protein including microalbuminuria, glucose, ketones as well as blood WBC and RBC sediments will be assessed. (	Baseline to Day 8
Change from baseline in urine drug & cotinine screen	: Urine will be collected and tested for cotinine and the following drugs or illicit substances: barbiturates, benzodiazepines, amphetamines, cocaine, opiates, and cannabis.	Baseline to Day 8
Change from baseline in pregnancy and assessments of fertility	A urine dipsick test will be performed.	Baseline to Day 8
