Brief Summary:
This is a single-center, open-label, non-randomized, single dose study in healthy male subjects. It was planned to enroll 2 cohorts of 5 subjects (10 subjects in total), with the target of achieving data in 4 evaluable subjects per cohort. Five subjects were to receive a single oral dose of APX001 and not more than (NMT) 3.1 megabecquerel (MBq) (84.0 microcurie [μCi]) 14C in the fed state. Five subjects were to receive a single IV administration containing APX001 and NMT 3.4 MBq (93.0 μCi) 14C in the fed state.

Primary Purpose: Treatment
Official Title: An Open Label, Single-Dose, Single-Period Study Designed to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C]-APX001 in Healthy Male Subjects After Oral and Intravenous Dosing
Actual Study Start Date : August 17, 2018
Actual Primary Completion Date : September 26, 2018
Actual Study Completion Date : September 26, 2018

Arm Intervention/treatment
Experimental: Cohort A
[14C]-APX001 Oral Solution
Drug: [14C]-APX001 Oral Solution
Total dose containing NMT 3.1 MBq (84.0 µCi) 14C

Experimental: Cohort B
[14C]-APX001 Solution for Infusion
Drug: [14C]-APX001 Solution for Infusion
Total dose containing NMT 3.4 MBq (93.0 µCi) 14C




Primary Outcome Measures :
  1. Mass balance recovery as measured by mass unit equiv/g after a single oral or single intravenous (IV) dose of carbon-14 (14C)-labelled APX001 ([14C]-APX001). [ Time Frame: 3 weeks ]
  2. Profiling of metabolites of [14C]-APX001 in plasma and excreta. [ Time Frame: 3 weeks ]
    Plasma, urine and feces samples from subjects dosed with [14C]-APX001 were analyzed using high resolution, accurate mass liquid chromatography tandem mass spectrometry (LC-MS/MS) with in-line fraction collection and off-line counting to obtain [14C]-radiochromatographic profiles and provide information on the nature of the radioactive components present, including chemical structure identification.


Secondary Outcome Measures :
  1. Elimination pathway of [14C]-APX001 following a single oral or single IV dose of [14C]-APX001. [ Time Frame: 3 weeks ]
    Amount of radioactivity recovered from urine and feces over time was measured by liquid scintillation counting (LSC) and expressed as a percentage of administered radioactivity.

  2. Extent of distribution of total radioactivity into blood cells following a single oral or single IV dose of [14C]-APX001. [ Time Frame: 3 weeks ]
    Amount of radioactivity in whole blood over time was quantified by LSC and expressed in ng equivalents free drug/g.

  3. Body mass index (BMI) of 18.0 to 32.0 kg/m2 or, if outside the range, considered not clinically significant by the investigator
  4. Good state of health (mentally and physically) as indicated by a comprehensive clinical assessment (detailed medical history and a complete physical examination)
  5. Must have been willing and able to communicate and participate in the whole study
  6. Must have had regular bowel movements (i.e. average stool production of ≥1 and

    ≤3 stools per day)

  7. Must have provided written informed consent
  8. Must have adhered to the contraception requirements defined in Section 9.4 of the protocol (Appendix 16.1.1)

Exclusion Criteria:

  1. Subjects who had received any IMP in a clinical research study within the previous 3 months or a similar 14C radioactive clinical trial within the previous 12 months
  2. Subjects who were study site employees, or immediate family members of a study site or sponsor employee
  3. Subjects who had previously been enrolled in this study.
  4. History of any drug or alcohol abuse in the past 2 years
  5. Regular alcohol consumption in males >21 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type)
  6. Current smokers and those who had smoked within the last 12 months. A breath carbon monoxide (CO) reading of greater than 10 ppm at screening and admission
  7. Current users of e-cigarettes and nicotine replacement products and those who had used these products within the last 12 months
  8. Radiation exposure, including that from the present study, excluding background radiation but including diagnostic x-rays and other medical exposures, exceeded 5 millisieverts (mSv) in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 2017, was to participate in the study
