Phase I study in health volunteers to assess the safety, tolerability and pharmacokinetics of escalating single doses and multiple doses of SP-8203
详细描述
This is a Phase I, single-center, randomized, double-blind, placebo-controlled study of the safety, tolerability, and PK of escalating single doses and multiple doses of SP 8203 in healthy adult male and female subjects.
In the SAD Part, the first cohort of 8 subjects will be randomly assigned to receive a single IV dose of either SP-8203 (n=6) or placebo (n=2). Following medical review of safety, PK, and biomarker data, subsequent cohorts of 8 new subjects will receive higher single doses of SP-8203 (6 subjects) or placebo (2 subjects). Dose escalation will continue until a single MTD of SP-8203 is identified. If a single-dose MTD is not defined within the projected dose range, additional cohorts of 8 subjects may be added to receive higher doses to achieve the objectives of the study. Alternate doses may be administered following medical review of the results of each cohort.
In the MAD Part of the study the first cohort of 8 subjects will receive a single dose of SP 8203 every day and 1 subject will receive a single dose of placebo every day for 7 consecutive days. Doses will be administered at the same time (± 15 minutes) every day. Following medical review of all safety and biomarker data, subsequent cohorts of 7 drug-naive subjects will receive higher single doses of SP-8203 (6 subjects) or placebo (2 subject) every day for 7 consecutive days. Study drug dose-escalation will continue until a multiple-dose MTD regimen of SP-8203 is identified. If a multiple-dose MTD is not defined within this range, additional cohorts of 8 subjects may be added to achieve the objectives of the study. Alternate doses and/or dosing regimens may be administered following medical review of the safety, biomarker, and PK results of the SAD Part, and prior cohorts in the MAD Part of the study.
The MTD will be defined as the highest dose that does not lead to unacceptable toxicity in one or more subjects based on the frequency, nature, and severity of AEs or other safety parameter abnormalities. The Investigator, Sponsor, and Medical Monitor will jointly assess the general safety and tolerability of each dose based on available data prior to escalating to the next higher dose. Successive higher doses will be administered only if previous doses are adequately tolerated. Intermediate doses may be tested, or a dose level may be repeated, as appropriate, depending on the safety profile observed.
Each subject will complete Screening, Baseline, Treatment, and Follow-Up Phases. The Screening Phase will be conducted on an outpatient basis within 30 days, but no sooner than 3 days, prior to the start of the Baseline Phase. The Baseline Phase will consist of admission to the CRU and final qualification assessments.

结局指标
主要结局
The incidence rate of adverse events, and adverse drug reaction in multiple ascending doses (MAD)
时间窗: Follow-up to 13 days after first administration
The safety of SP-8203 will be evaluated by monitoring treatment-emergent adverse events (AE), changes in 12 lead electrocardiograms (ECG), clinical laboratory tests, vital signs, and physical examinations, as well as clinically important changes in heart rate.
The incidence rate of adverse events, and adverse drug reaction in single ascending doses (SAD)
时间窗: Follow-up to 7 days after administration
The safety of SP-8203 will be evaluated by monitoring treatment-emergent adverse events (AE), changes in 12 lead electrocardiograms (ECG), clinical laboratory tests, vital signs, and physical examinations, as well as clinically important changes in heart rate.
Pharmacokinetics in single ascending doses (SAD)
时间窗: within 3 days of administration
Plasma concentrations of SP-8203 will be measured by a validated liquid chromatography-tandem mass spectrometry assay procedure and PK parameters will be determined. Urine will be collected predose and at specified intervals postdose for the determination of SP-8203 renal clearance.

时间窗: within 9 days of first administration
Plasma concentrations of SP-8203 will be measured by a validated liquid chromatography-tandem mass spectrometry assay procedure and PK parameters will be determined. Urine will be collected predose and at specified intervals postdose for the determination of SP-8203 renal clearance.
