Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Healthy male volunteers will be screened within 28 days prior to commencement of dosing.

Study consists of 3 cohorts, each cohort consisting of 8 participants with 6 participants receiving (Z)-Endoxifen topical and 2 participants receiving placebo topical. Three dose levels of topically applied (Z)-Endoxifen (2mg, 6mg, and 10 mg) will be investigated in the 3 cohorts. Participants will be admitted in the clinical facility on Day-1 and will receive the IMP in pre-sealed sachets for topical application on Day 1. They will be discharged on Day 2 and supplied with study drug sachets and asked to self-administer daily one sachet to each of the breast for 28 days.
Participants will return to the clinic weekly for PK sampling and assessment, as well as on Days 4, 31, 33 and 35.

Outcomes
Primary outcome [1] 305257 0
To assess the safety and tolerability of (Z)-endoxifen when administered topically to the breast of healthy male volunteers and will include recording the incidence and severity of adverse events, vital sign parameters, physical examination findings, electrocardiogram parameters and clinical laboratory parameters (serum chemistry, hematology, coagulation, urinalysis).
Timepoint [1] 305257 0
The safety assessments mentioned above are composite primary outcome and will be done at each of the visits, weekly for a month and on days 4, 31, 33 and 35.
The blood pressure and pulse will be assessed by pulse oximetry while respiratory rate, physical examination will be assessed clinically. Temperature will be assessed by using a tympanic thermometer while an ECG will be recorded by an instrument which involves the placement of electrodes on the chest wall.
Blood will be collected for hematology, coagulation and clinical chemistry lab assessments while urine will be collected for urinalysis.
Secondary outcome [1] 344646 0
To assess the pharmacokinetics of multiple doses of (Z)-endoxifen when administered topically to the breast of healthy male volunteers.
Pharmacokinetic parameters which will be assessed include Cmax, Tmax, AUC0-24h, t1/2
Timepoint [1] 344646 0
Blood sampling for pharmacokinetic analysis will be performed at Day 1, Day 4, Day 7, Day 14, Day 21, Day 28, Day 29, Day 31, Day 33 and Day 35.
Secondary outcome [2] 344685 0
Assess the side effects associated with (Z)-endoxifen treatment using the modified FACT-ES questionnaire.
Timepoint [2] 344685 0
To be performed on Day 1, Day 7, Day 14, Day 21, Day 28 and Day 35.
