Clinical Trial Summary

This is a single-center, open-label, dose-escalating study to evaluate the safety, pharmacokinetics, immunogenicity, and preliminary efficacy of single and multiple subcutaneous injection TK006 in patients with breast cancer-related bone metastases.

Description:

This is an single-center, open-label, dose-escalating study to evaluate the safety, pharmacokinetics, immunogenicity, and preliminary efficacy of single and multiple subcutaneous injection TK006 in patients with breast cancer-related bone metastases. It contains 4 cohorts：60 mg single-dose conhort, 120 mg single-dose conhort, 180 mg single-dose conhort and 120 mg Q4W （one dose every 4 weeks, 3 dose totally） conhort.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Frequency of adverse events (AEs) and serious adverse events (SAEs) which are related to TK006 assessed by CTCAE v4.03	Collect the information of AEs and SAEs, vital sign, physical examination, laboratory examination and electrocardiogram during the trial.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	Area under the plasma concentration-time curve from time zero to time 'last' where last is the last time point after administration [AUClast]	Calculated by the linear trapezoidal method.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	Area under the plasma concentration-time curve from time zero to infinity [AUC0-inf]	Calculated by the linear trapezoidal and extrapolation method.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	Maximum observed maximum plasma concentration [Cmax]	The maximum (or peak) serum concentration that TK006 achieves after the drug has been administrated and before the administration of a second dose.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	Time to reach the maximum observed plasma concentration [Tmax]	The time at which the Cmax is observed.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	Terminal elimination half-life[T1/2]	The time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose.	single dose cohort:112 days, multiple dose cohort:140 days
Secondary	bioavailability corrected apparent volume of the central compartment cleared of drug per unit [Cl/F]	The apparent volume of the central compartment cleared of drug per unit time was estimated using the formula: Cl/F = Dose / AUC0-8	single dose cohort:112 days, multiple dose cohort:140 days
