Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

The objective of this study is to evaluate the safety, tolerance, pharmacokinetics and the potential immunological reaction of single intravenous recombinant human thymosin β4（NL005）or placebo 0.5, 2.0,5.0μg/kg in Chinese healthy volunteers.30 volunteers will be randomly assigned to one of three groups to receive either NL005 or placebo for 10 consecutive days.

Primary outcomes11

Outcomes the sponsor listed as primary.

Maximum Tolerated Dose (MTD) .
Time frame · Day-7、-1、1、2、3、4、5、6、7、8、9、10、14、28.
Registry description
Determine maximum tolerated dose (MTD) or dose-limiting toxicity (DLT) by comprehensive evaluation of drug safety by adverse event observation, vital signs, physical examination, laboratory examination, electrocardiogram, etc. In this study, DLT was defined as liver, kidney, heart and mental nervous system toxicity of level 2 or above or blood system toxicity of level 3 or above and other systemic adverse events occurred within 14 days after drug administration, and the adverse events were judged to be related to the experimental drug use.If more than 3 (including 3) DLT cases are present in any dose group, the test should be terminated. The previous dose of this dose is considered the maximum tolerated dose (MTD).
Number of participants with treatment-related adverse events as assessed by CTCAE v4.03.
Time frame · Day-7、-1、1、2、3、4、5、6、7、8、9、10、14、28.
Registry description
Determine maximum tolerated dose (MTD) or dose-limiting toxicity (DLT) by comprehensive evaluation of drug safety by adverse event observation, vital signs, physical examination, laboratory examination, electrocardiogram, etc. All adverse events were determined according to NCI CTCAE4.03.CTCAE4.03 was classified into grades 1 to 5, in which grade 1 was mild adverse event and grade 5 was death due to adverse event.According to NCI CTCAE4.03.

Time frame · Day 1、14、28.
Registry description
Approximately 5mL venous blood was collected from subjects before, 14 days after, and 28 days after administration for ADA study of rh-Tβ4 in healthy subjects.After the 28th-day follow-up period, subjects who confirm that ADA results are positive should be reexamined every 30 days (±3 days) until the results turn negative or the titer level is stable for two consecutive times.
