Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cohort A: 0.15 mg/kg Cohort B: 0.45 mg/kg Cohort C: 1.0 mg/kg Cohort D: 2.0 mg/kg Cohort E: 3.0 mg/kg Cohort F: 4.0 mg/kg Cohort G: 5.0 mg/kg
Doses of IMP will be administered intravenously on the morning of Day 1 following an overnight fast (minimum 8 hours).
During the Screening Period (within the 28 days prior to the subject receiving TP-271 or placebo) each subject will be assessed for eligibility. Each subject must sign and date an ICF prior to undergoing any study-related procedures.
All cohorts will follow the same study design (Figure 1). On Day -1, subjects will be admitted to the study unit so their eligibility can be confirmed. Subjects will be required to stay overnight at the study unit on Day -1. On Day 1, eligible subjects will be enrolled and randomized to receive either TP-271 or placebo. Subjects will be required to stay at the study unit from Day 1 through Day 5 to assess safety and obtain required PK samples. On Day 5, subjects will be discharged from the study unit. A final safety assessment will be performed once between Day 7 and Day 10 following the subject's dose of IMP.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Voluntarily sign an IRB/Research Ethics Committee (IRB/REC)-approved ICF to participate in the study after all relevant aspects of the study have been explained and discussed with the subject and before undergoing any study related procedures.
3. Have a body mass index (BMI) ≥18.0 and ≤33.0 kg/m2.
4. Be clear of any history of, and have negative screen for, HIV 1 and 2 and hepatitis B and C.
5. Have the ability to communicate with the investigative site staff in a manner sufficient to carry out all protocol procedures as described.
6. Females must be of non-child bearing potential, either 1-year post-menopausal or surgically sterile (bilateral oophorectomy, bilateral tubal ligation, or complete hysterectomy).
7. Male subjects must be willing and able to use a barrier method of birth control or practice abstinence (even if they have had a vasectomy) from dosing through 90 days after the dose of IMP.
