Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
n=24healthy female subjects will be divided evenly into 2 groups, Group 1 (n = 12) receiving Z-endoxifen 4mg capsules or matching placebo and Group 2 (n = 12) receiving Z-endoxifen 4mg tablets or placebo.

Subjects will all complete screening procedures from day -28 to day -2 prior to dosing. subjects will then check into the clinical facility on Day -1. Following confirmation of eligibility on Day 1 each subject will be receive 1 dose of study drug in the clinic. Subjects will remain in-house until Day 2, when they will check out of the facility.
On Days 4, 6 and 15 subjects will return to the clinical facility to attend out-patient visits including safety tests and pharmacokinetics (PK).
A Safety and PK Review Committee will review safety and PK data for all patients (Group 1 and Group 2) up to and including up to Day 6 samples. The Committee we determine if the study can safely move to the Multiple Administration Dosing (MAD) and whether Group 1 and Group 2 or Group 2 alone will be dosed in MAD. If the SAD PK results show equivalence for capsule and tablet, only the tablet group will be dosed in the MAD.
On Day 26 subjects will attend an out-patient visit for safety and PK and will then be administered one dose of allocated study drug. The subject will continue to take 1 daily dose of study drug at home (or in clinic on out-patient days) for 14 days. Participants will complete a daily (paper) diary to record when study drug is dosed; adverse events and concomitant medications can also be recorded in the diary. Subjects will be reminded to return the study drug bottle, even if empty, at their clinic visit for the site to perform accountability and, together with the diary, to assess participant study drug compliance.
Subjects will return to the clinic for safety assessments and PK on Day 32.
Subjects will check in to the clinical facility on Day 38 and on Day 39 and undergo study assessments including blood draws for safety and PK before taking the final dose of study medication (Day 39). Subjects will remain at the clinical facility until Day 40 when they will be discharged.
Subjects will then attend out-patient visits on Days 42, 44 and 46 for safety assessments.
All study visits (out patient and in-house) will consist of PK and safety assessments.
Intervention code [1] 313785 0
Treatment: Drugs
Comparator / control treatment
A matching placebo will be the control for each intervention.

The matching placebo capsule contains the requisite amount of microcrystalline cellulose, an inert common capsule and tablet excipient.

The matching placebo tablet consists of the same ingredients s the active tablet, without the (Z)-endoxifen with added excipients to yield the same weight and size.
Control group
Placebo

Outcomes
Primary outcome [1] 319270 0
Determine the pharmacokinetics of a single and multiple oral doses of a previously studied oral (Z)-endoxifen capsule with a (Z)-endoxifen tablet in healthy female volunteers.

Mean and individual (Z)-Endoxifen concentration-time curves will be tabulated for each treatment, and presented graphically with concentration displayed on a linear and logarithmic scale.
Concentrations of (Z)-Endoxifen collected at specified time points post-dose after Day 1 dose (single dose) and after 14 days of once-daily administration will be used to calculate pharmacokinetic parameters for each participant.
The pharmacokinetic parameters will be determined using non-compartmental analysis methods.
Pharmacokinetic parameters will be summarised by treatment using descriptive statistics including mean,
standard deviation (SD), and coefficient of variation (CV), minimum and maximum. In addition, geometric means and geometric CV will be calculated for AUC and Cmax.

Other design features
Safety and Pharmacokinetic results from Single Administration Dose (SAD) will be reviewed and submitted to the ethics committee for authorisation of progression of study to Multiple Administration Dose (MAD) part of the study.

Type of endpoint/s
Pharmacokinetics
Statistical methods / analysis
This study is a pharmacokinetic study with (Z)-Endoxifen and as such no formal sample size calculation was performed. Results from this study will be utilized for sample size calculations of subsequent studies.
Screening data will be tabulated by and summaries per treatment group. Safety endpoints will be summarised by treatment group. Treatment -emergent adverse events (AEs) will be coded using the latest version of MedDRA. Incidence and frequency of AEs and serious adverse events (SAEs) will be summarised by treatment group according to SOC and Preferred Terms. Summaries of Treatment-Emergent Adverse Events (TEAE) will be presented by severity and relationship.
The duration of AEs will be determined and included in listings.
Cardiac (12-lead ECG), vitial signs and safety laboratory parameters will be summaried by treatment group and each time point using descriptive statistics.
Pharmacokinetic (PK) data:
The mean and individual Z-endoxifen concentration-time curves will be tabulated for each treatment. Concentrations of Z-endoxifen colelcted at specified time points post-dose after Dat 1 dose (SAD) and after 14 days of once-daily dosing will be used to calculate PK parameter for each participant.
PK parameters will be determined using non-compartmental analysis methods and summarised per treatment group.
Mean and Analysis will be perfromed to assess time dependence and accumulation (multiple dose), and attainment of steady state (multiple;e dose).
Statistical analysis will be performed on the PK parameters using validated statistical software.

Summary
Brief summary
The purpose of this study is to test the safety and tolerability of two types of a potential breast cancer treatment called endoxifen.

Who is it for?
You may be eligible for this study if you are a healthy female aged 18-65. [***Please note participants who have cancer are not eligible for this study.***]

Study details
Participants in this study will be organised into two groups. One group will receive capsules to be taken by mouth, and the other group will receive tablets, to be taken by mouth. Within the capsule and tablet groups, participants will be randomised (by chance) to either the active drug or a placebo. Neither the participant nor investigators will know who gets the active or placebo drug. Initially, only a single capsule or tablet will be taken. After checking the results of this first day, participants may take their assigned tablet/capsule once a day for another 14 days. As part of this study, all participants will need to provide blood samples, urine samples, answer questionnaires and have a physical exam.
