A Study to Determine the Tolerability of Intranasal LMN-301

Study Overview
=================
Brief Summary
-----------------
LMN-301 is to prevent infection by SARS-CoV-2 (the virus causing Covid-19 disease) in uninfected individuals. This study aims to assess whether the formulation will cause irritation when administered in the nose, and how long its protective effects will last. Thirty five healthy adult volunteers will participate in this study.

Exclusion Criteria Individuals will be excluded from this study if they meet any of the following criteria: History or presence of clinically significant disease, including (but not limited to) clinically significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological or psychiatric disease, including any acute illness or surgery within the past 3 months prior to screening determined by the PI to be clinically relevant. Known allergy or previous anaphylaxis to any components of the investigational product Allergies, history of allergic disease or chronic respiratory diseases including mild asthma. History of childhood asthma or childhood allergies are not exclusionary. History of nasal or upper respiratory pathology or abnormalities Ongoing, defined as within 30 days of dosing through end of follow-up, usage of nasal spray or nasal drops Treatment with an experimental device or compound within 30 days of the first dose of study drug. Treatment within 30 days of the first dose of the study medication or planned use within the study period with immunomodulator or immunosuppressant agent or medicines (over the counter [OTC], herbal, prescription, or supplement) with significant activity in the respiratory tract. Pregnancy, anticipated pregnancy, or breastfeeding/lactating Alcohol or drug abuse/dependency (defined as more than 10 standard drinks per week or more than 4 standard drinks on any one day, where 1 standard drink is 10 g of pure alcohol) within 3 months prior to screening. Positive urine toxicology screen for drugs of abuse. Repeat testing is allowed at investigator discretion. Tobacco or nicotine consumption is not permitted from screening and until the end of follow-up. Positive alcohol breath test. Repeat test is allowed at investigator discretion. Individuals unable or unwilling to provide adequate informed consent COVID-19 positive Positive test results for active human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV) antibodies at screening.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Occurrence of adverse events as assessed by CTCAE v5.0 for 28 days after the first dose of LMN-301 | All AEs will be coded using the latest version of MedDRA by system organ class (SOC) and preferred term, classified from verbatim terms. The number of treatment-emergent AEs (TEAEs) as well as the number and percentage of participants with at least one TEAE, will be summarized by SOC and preferred term. Summaries of TEAEs by severity as assessed by CTCAE v5.0 and relationship will also be presented. Summaries will also be presented for SAEs, TEAEs leading to death or study withdrawal. The duration of all AEs will be determined and included in the listings. Solicited and unsolicited TEAEs will be summarized separately. | Daily for 28 days | 
| Number of participants discontinuing from the study | The number of participants discontinuing from the study and the reason for discontinuation will be summarized. | For 28 days after the first dose of LMN-301 | 
| Changes from baseline vital sign measures (systolic and diastolic blood pressure, pulse rate, oral temperature, and respiratory rate) | Observed values and changes from baseline for vital signs (systolic and diastolic blood pressure, pulse rate, oral temperature, and respiratory rate) will be summarized at each scheduled timepoint using descriptive statistics. | In part A vital signs are measured on Days 1 (5 timepoints), 2, 8 and 14. In part B vital signs are measured on Days 1 (5 timepoints), 3 or 4, 7, 10 or 11, 14 and 28. | 
| Changes from baseline safety laboratory measures (hematology, clinical chemistry and coagulation) | Clinical laboratory safety data will be summarized by laboratory measure (hematology, clinical chemistry and coagulation). Observed values and changes from baseline for continuous clinical laboratory parameters will be summarized at each scheduled timepoint using descriptive statistics. Categorical clinical laboratory data will be summarized at each scheduled timepoint using participant counts and percentages. The clinical assessment of laboratory data will be summarized at each scheduled timepoint using participant counts and percentages. Individual participant profiles will be presented for any laboratory parameters with at least one post-dose value outside the laboratory's reference ranges that is deemed clinically significant. | For Part A on Days 1, 2, 8 and 14 and For Part B on Days 1, 3 or 4, 7, 14 and 28 | 
| Changes from baseline ECG parameters (PR interval, QRS duration, QTcB, QTcF and ventricular heart rate) | The following ECG parameters will be analyzed: PR interval, QRS duration, QTcB, QTcF and ventricular heart rate. Observed values and changes from baseline for ECG parameters will be summarized at each scheduled timepoint using descriptive statistics. For QTcF, the number of participants with values greater than 450 (and 480, 500) msec or an increase from baseline of at least 30 (and 60) msec will also be tabulated, in accordance with ICH E14 | Screening and Day 14 | 
| Changes from baseline nasal symptoms using the Sino-Nasal Outcome Test (total score) | Scores will be totaled for all 22 symptoms. Changes from baseline in individual total SNOT-22 scores will be calculated as the post-baseline value minus the baseline value. Thus, a negative change will reflect an improvement in the corresponding score. Observed values and changes from baseline will be summarized at each scheduled timepoint by treatment using descriptive statistics and tabulated for each cohort (dose level) and overall. Individual symptoms will be listed, with the 5 most important issues flagged. The total SNOT score will also be included in the listing. | For Part A Days 1 and 8. For Part B Days 1, 7, 14 and 28 |
