A Phase 1, randomized, double-blind, placebo-controlled dose escalation trial of four dose cohorts of 10 subjects (1: 10mg, 2: 25mg, 3: 50mg, 4: 100mg).
Full description
A Phase 1, randomized, double-blind, placebo-controlled dose escalation trial of four dose cohorts of 10 subjects (1: 10mg, 2: 25mg, 3: 50mg, 4: 100mg). Dose escalation will not occur until safety data through Day 8 is reviewed by the Safety Review Committee (SRC). The study will consist of a twenty-eight day screening period, 12-hour clinic stay, and 120-day (Cohorts 1-3) or 180-day (Cohort 4) outpatient follow-up. The primary objective of this study is to assess the safety and tolerability of escalating doses of G03-52-01 administered intramuscularly (IM) in healthy adult subjects. The secondary objectives are to evaluate the pharmacokinetics (PK) and immunogenicity of escalating IM doses of G03-52-01.

The hemoglobin, platelet count, white blood cell count and absolute neutrophil count are not below the LLN and ≤ULN x 10%
• Abnormalities in mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), mean platelet volume (MPV), and nucleated red blood cell count (NRBC CT), which are included in a complete blood count with differential, will not be exclusions.
The urine dipstick results on protein, glucose and blood are negative or trace
Chemistry screening laboratory tests as outlined in Section 7.5.1.4 are in the normal reference range
The urine drug screen is negative
Breathalyzer test is negative
Available for follow-up for the duration of the study
Agrees not to participate in vigorous activity 72 hours prior to dosing through day 15 post dosing
Exclusion criteria
History of a chronic medical condition that would either interfere with the accurate assessment of the objectives of the study or increase the risk profile of the subject.
• Note: Chronic medical conditions include but not limited to diabetes; Asthma requiring use of medication in the year before screening; Autoimmune disorder such as lupus, Wegener's, rheumatoid arthritis, thyroid disease; Coronary artery disease; Chronic hypertension; History of malignancy except low-grade (squamous and basal cell) skin cancer thought to be cured; chronic renal, hepatic, pulmonary, or endocrine disease (except previous asthma which has required no treatment for the past year);

• Note: Severe allergic reaction is defined as any of the following: anaphylaxis, urticaria, or angioedema
A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 milliseconds)
Clinically significant abnormal electrocardiogram at screening.
• Note: Clinically significant abnormal ECG results include but not limited to: complete left or right bundle branch block; other ventricular conduction block; 2nd degree or 3rd degree atrioventricular (AV) block; sustained ventricular arrhythmia; sustained atrial arrhythmia; two Premature Ventricular Contractions in a row; pattern of ST elevation felt consistent with cardiac ischemia; or any condition deemed clinically significant by a study investigator
Positive serology results for HIV, HBsAg, or HCV antibodies
Febrile illness with temperature ≥38°C within 7 days of dosing
Pregnant or breastfeeding
Donated blood within 56 days of enrollment
Known allergic reactions to any of the study product components present in the formulation or in the processing, as listed in the Investigator Brochure
Treatment with another investigational drug within 28 days of dosing
Treatment with a monoclonal antibody within 3 months of enrollment.
Receipt of antibody (e.g. TIG, VZIG, IVIG, IM gamma globulin) or blood transfusion within 6 months or within 5 half-lives of the specific product given
Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements
Use of H1 antihistamines or beta-blockers within 5 days of dosing
Use of any prohibited medication within 28 days prior to study entry or planned use during the study period
• Note: Prohibited medications include immunosuppressives (except Nonsteroidal Anti-Inflammatory Drugs [NSAIDS]); immune modulators; oral corticosteroids (topical/intranasal steroids are acceptable); anti-neoplastic agents; any vaccine (licensed or investigational). Subjects will be eligible to receive any authorized COVID-19 vaccine after they complete Study Day 8
Previous exposure to botulinum toxin, receipt of antibodies against botulinum toxin, or previous treatment with equine antitoxin
Any previous injection or planned injection within 4 months after enrollment of botulinum toxin for cosmetic reasons, spastic dysphonia, torticollis, or any other reason
Any specific condition that in the judgment of the investigator precludes participation because it could affect subject safety
Plans to enroll or is already enrolled in another clinical trial* that could interfere with safety assessment of the investigational product at any time during the study period
• Note: Includes trials that have a study intervention such as a drug, biologic, or device
Is a study site employee or staff
• Note: Site employees or staff include the PIs and sub-investigators or staff who are supervised by the PI or Sub-Investigators
