Subjects randomized to the DP(Drug product) active treatment will receive CG- SpikeDown intranasally once daily for one or seven days at either a low (25 mg) or planned (50 mg) dose.\n\nSubject recruitment will be conducted via study advertisement on social media, and subjects will be adequately compensated. The subjects will arrive each day at the clinic to receive the treatment and will be hospitalized for safety monitoring for the first 24 hours post-DP or vehicle administration.', 'detailedDescription': 'This is a phase 1, Randomized, Double-blinded, Vehicle-controlled, Single and Multi-Dose, Dose Escalation Study, which will assess the safety of the Caregen CG-SpikeDown drug self-administered intranasally, for healthy subjects.\n\nThe study will include 16 healthy subjects and will be conducted in a clinic under complete supervision of the clinical team. The study will start with evaluation of the lowest dose, that will be increased gradually as long as no safety issues arise.\n\nAt the first stage of the study, three (3) subjects will be randomized in a 1:2 ratio to receive vehicle treatment or the active drug, respectively. Each of the 3 subjects will receive a single 25 mg dose of the assigned treatment. These subjects will be referred as Cohort 1. If no safety issues arise, the study will proceed simultaneously to the second and third stages, as depicted in Figure 1 Study Flow Chart.\n\nAt the second stage of the study, additional three (3) subjects will be enrolled and randomized in a 1:2 ratio to receive vehicle treatment or the active drug, respectively. Each of the 3 subjects will receive a single 50 mg dose of the assigned treatment. These subjects will be referred as Cohort 2. If no safety issues arise, the study will proceed to the 4th stage.\n\nAt the third stage of the study, additional three (5) subjects will be enrolled. The first 2 subjects (out of the 5 subjects) will receive an open label DP treatment-a daily 25 mg dose for 7 days. The open-label subjects will undergo PK assessments as described in the SOA. The next 3 subjects will be randomized in a 1:2 ratio to receive vehicle treatment or the active drug, respectively. Each of the 3 subjects will receive a daily 25 mg dose of the assigned treatment for 7 days. These subjects will be referred as Cohort 3.\n\nAt the fourth stage of the study, additional three (5) subjects will be enrolled. The first 2 subjects (out of the 5 subjects) will receive an open label DP treatment-a daily 50 mg dose for 7 days. The open-label subjects will undergo PK assessments as described in the SOA. The next 3 subjects will be randomized in a 1:2 ratio to receive vehicle treatment or the active drug, respectively. Each of the 3 subjects will receive a daily 50 mg dose of the assigned treatment for 7 days. These subjects will be referred as Cohort 4.\n\nThe main objective of this study is to assess the toxicity and the pharmacokinetic (PK) parameters of the Drug Product (DP). Subjects will be recruited to the study via study advertisement on social media and the subjects will be adequately compensated. The DP will be self-administered intranasally once daily for 1 day or seven days, depending on the study cohort. PK parameters will be evaluated for 4 subjects participating in the 7 daily DP doses study cohorts. Blood samples for this purpose will be collected at several time points (as described in SOA) during Day 1 and Day 7 of treatment. Toxicity will be evaluated during the entire study period.\n\nPatients receiving a single dose will arrive for a follow-up visit 72 hours following DP administration (24 hours following hospital discharge), again 7 days (+-2 days) following DP administration, and again 14 days (+-2 days) following DP administration. Subjects receiving a daily dose for 7 days will be followed up 14 days (+-2 days) following initial DP administration (7 days (+-2 days) following final DP administration).\n\nSafety review by the DSMB will occur following treatment of the last subject in each study arm.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Stage I Inclusion Criteria\n\n1.
