Study Details

Study Description

Brief Summary

The main aim of this study is to assess how the human body of adults with advanced or metastatic solid tumors absorbs, distributes, metabolizes and excretes subasumstat following a single 1 hour infusion of subasumstat.

The study consists of two parts. In Part A, participants will receive a single infusion of C14 radiolabeled subasumstat. In Part B, participants will receive subasumstat treatment for up to 1 year.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

The drug being tested in this study is called [14C]subasumstat. [14C]Subasumstat is being tested to assess mass balance and absorption, distribution, metabolism, excretion (ADME) of people who have advanced or metastatic solid tumors.

The study will enroll approximately 10 patients. Participants will be enrolled to receive a single dose of [14C]subasumstat:

  • [14C]Subasumstat 90 mg

Participants will be administered with a single dose of [14C]subasumstat 90 mg as a 1-hour intravenous (IV) infusion on Day 1 of Part A. All participants will be monitored for up to 14 days postdose. Participants will then have an option to enter Part B of the study to receive non-radiolabelled subasumstat 90 mg, IV infusion on Days 1, 4, 8, and 11 of a 21-day cycle for 3 cycles up to maximum treatment duration of 1 year.

This multi-center trial will be conducted in Hungary. The overall study duration is 12 months for Part A and 24 months for Part B.

    Outcome Measures

    Primary Outcome Measures

      Cumulative amount of [14C]-radioactivity excreted in urine up to the last sampling interval.

    2. Cumulative Percentage of Fecal Recovery [Up to 14 days postdose]

      Cumulative amount of [14C]-radioactivity excreted in feces up to the last sampling interval.

    3. Cumulative Percentage of Combined Recovery [Up to 14 days postdose]

      Cumulative amount of [14C]-radioactivity excreted in urine, and feces up to the last sampling interval.

    4. Percentage Of Recovered Total Radioactivity (TRA) In Urine And Feces [Up to 14 days postdose]

      Percentage of recovered TRA in urine and feces for each interval over the entire period of collection will be reported.

    Secondary Outcome Measures

    2. Tmax: Time of First Occurrence of Cmax for Subasumstat and TRA in Plasma and Whole Blood [Predose on Day 1 and at multiple time points postdose up to Day 14]

    3. AUClast: Area Under the Plasma Concentration-Time Curve From Time 0 to the Time of the Last Quantifiable Concentration for Subasumstat and TRA in Plasma and Whole Blood [Predose on Day 1 and at multiple time points postdose up to Day 14]

    4. Terminal Disposition Phase Half-life (T1/2z) for Subasumstat and TRA in Plasma and Whole Blood as Permitted by Data [Predose on Day 1 and at multiple time points postdose up to Day 14]

    5. Clearance (CL) for Subasumstat and TRA in Plasma and Whole Blood as Permitted by Data [Predose on Day 1 and at multiple time postdose points up to Day 14]

    6. Volume of Distribution at Steady-state (Vss) for Subasumstat and TRA in Plasma and Whole Blood as Permitted by Data [Predose on Day 1 and at multiple time points postdose up to Day 14]

    7. AUC∞: Area Under the Plasma Concentration-time Curve from Time 0 to Infinity for Subasumstat and TRA in Plasma and Whole Blood as Permitted by Data [Predose on Day 1 and at multiple time points postdose up to Day 14]

    8. Cumulative Amount of Unchanged Subasumstat and TRA Excreted into the Urine (Aeurine) [Predose on Day 1 and at multiple time points postdose up to Day 14]
