Brief Summary:
This is a nonrandomized, open-label, dose escalation, safety, activity, and PK study to determine the MTD and optimal dosing regimen of Oradoxel. No control group has been included.

Condition or disease Intervention/treatment Phase
Solid Tumor Drug: Oradoxel Phase 1

Detailed Description:

This is a multicenter, open-label, safety, tolerability, pharmacokinetic, and activity study. Eligible subjects will be adults with advanced solid malignancies.

Groups of 3 to 6 subjects will receive a single dose of Oradoxel and will be followed for toxicity. If non linearity in PK is observed, additional subjects will receive Oradoxel as 2 single daily doses once every three weeks. Subjects who tolerate the drug and have stable disease or better response will be eligible to receive ongoing treatment.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 24 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Dose Regimen-Finding Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Activity of Oradoxel Monotherapy in Subjects With Advanced Malignancies
Actual Study Start Date : April 20, 2017
Estimated Primary Completion Date : April 2019
Estimated Study Completion Date : December 2019

Drug Information available for: Docetaxel

Arm Intervention/treatment
Experimental: Oradoxel
To determine the MTD of Oradoxel (oral docetaxel and oral HM30181A) when administered once every 3 weeks, then to determine the MTD of Oradoxel (oral docetaxel and oral HM30181A) when administered for two days every three weeks.
Drug: Oradoxel
oral docetaxel will be supplied in capsules and oral HM30181A-UK tablets
Other Name: oral docetaxel + oral HM30181A




Primary Outcome Measures :
  1. The maximum tolerated dose (MTD) of Oradoxel based on dose-limiting toxicity (DLT) in subjects with advanced malignancies [ Time Frame: 3 weeks ]
    The MTD will be the highest dose at which no more than 1 of 6 subjects experience a DLT during treatment and Oradoxel pharmacokinetics are acceptable.


Secondary Outcome Measures :
  1. Safety assessment using AEs of Oradoxel [ Time Frame: Weekly, up to 24 months ]
  2. Safety assessment using SAEs of Oradoxel [ Time Frame: Weekly, up to 24 months ]
  3. Laboratory evaluation for hematology [ Time Frame: Weekly, up to 24 months ]
  4. Blood chemistry [ Time Frame: Weekly, up to 24 months ]
  5. Urine analysis [ Time Frame: Weekly, up to 24 months ]
  6. Periodic measurements of ECGs [ Time Frame: Screening, Day 1, every 6 weeks thereafter up to 24 months ]
  7. Periodic measurements of vital signs [ Time Frame: Weekly, up to 24 months ]
  8. The incidence of unacceptable toxicity with Oradoxel [ Time Frame: 24 months ]
    Unacceptable toxicity graded according to CTCAE v4.03

  9. The recommended Phase 2 dose (RP2D) of Oradoxel [ Time Frame: 24 months ]
    Upon determination of the overall MTD for Oradoxel, the safety and PK profile of the study treatment from all Treatment Periods will be reviewed to determine the recommended Phase 2 dose.

  10. The amount of docetaxel and HM30181A in blood stream by Area under the plasma concentration versus time curve (AUC) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  11. The peak plasma concentration (Cmax) and Minimum plasma concentration (Cmin) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  12. A biological half-life or elimination half-life (t1/2) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  13. The accumulation ratio (R) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  14. The apparent total clearance of the drug from plasma (CL/F) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  15. The apparent volume of distribution (Vd/F) [ Time Frame: Part 1: 16 timepoints over 504 hours; Part 2: 26 timepoints over 480 hours ]
  16. To evaluate tumor response [ Time Frame: Every 12 weeks, up to 24 months ]
    Tumor response will be evaluated according to RECIST v1.1
