Brief summary
The primary objective of the study is to • Investigate the relative bioavailability of sorafenib as 400 mg (4 x 100 mg) tablet for oral suspension formulation in comparison to 400 mg (2 x 200 mg) marketed tablet formulation. The secondary objectives of this study are to * Evaluate the dose proportionality in sorafenib pharmacokinetics for sorafenib tablet for oral suspension formulation after administration of 200 mg (2 x 100 mg) and 400 mg (4 x 100 mg) dose of sorafenib in fasted state * Evaluate the effect of food on the pharmacokinetics of the tablet for oral suspension formulation after administration of a single dose of 400 mg sorafenib (4 x 100mg) * Evaluate the taste and palatability of sorafenib (both formulations) * Assess the safety and tolerability of sorafenib tablet for oral suspension in healthy male subjects

Inclusion criteria
* Healthy male subjects between the ages of 18 (inclusive) and 45 years (inclusive) at the first screening visit. * Body mass index (BMI) between 18.0 (inclusive) and 32.0 kg / m² (inclusive). * Non-smoker or former smoker who has stopped smoking at least 3 months before the first study drug administration * Ability to understand and follow study-related instructions * Any subject who is a sexually active man and has not been surgically sterilized must consent to use a condom during intercourse and ensure that his female partner practices adequate contraception, or he must be willing to refrain from sexual intercourse from the beginning of the trial until 30 days after last study drug administration.
Exclusion criteria
* Medical and surgical history: * Failure of a major organ system or a medical disorder that would impair the subject's ability to complete the study or that would alter the absorption and pharmacokinetics of the study drug * Active infections or other medical, psychological or social problems of sufficient severity to limit full compliance with the trial * Known severe allergies, non-allergic drug reactions, or multiple drug allergies * History of clinically significant metabolic, renal, hepatic, or cardiovascular disease or central nervous system disorder * Clinically significant illness within 30 days before first study drug administration. * Febrile illness within 1 week before the first study drug administration * Known hypersensitivity to study drug * Incompletely cured pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal * Electrocardiogram (ECG), blood pressure, heart rate: * Clinically relevant findings in the ECG (e.g. a second- or third-degree AV block, prolongation of the QRS complex over 120 msec or of the QTc-interval over 450 msec) * Laboratory examination: * Clinically relevant deviations of the screened laboratory parameters from reference ranges (especially for gamma-GT, ALT, AST, or bilirubin) * Positive results for hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibodies (anti-HCV), human immune deficiency virus antibodies (anti-HIV)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Concentration Versus Time Curve From Zero to Last Data Point Greater Than Lower Limit of Quantitation (LLOQ) of Sorafenib in Plasma (AUC[0-tlast]) After Single Oral Dose | Pre-dose (0 hour) to 120 hours post-dose | Area under the concentration versus time curve from zero to the last data point greater than LLOQ after single dose of sorafenib were measured. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |
| Maximum Observed Drug Concentration After Single Dose Administration (Cmax) of Sorafenib in Plasma | Pre-dose (0 hour) to 120 hours post-dose | Maximum observed drug concentration after single dose administration of sorafenib in plasma was measured. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Concentration Versus Time Curve From Zero to Infinity After Single Dose Divided by Dose (AUC/D) of Sorafenib in Plasma | Pre-dose (0 hour) to 120 hours post-dose | Area under the concentration versus time curve from zero to infinity after single dose divided by dose of sorafenib in plasma. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |
| Area Under the Concentration Versus Time Curve From Zero to Last Data Point Divided by Dose (AUC[0-tlast]/D) of Sorafenib in Plasma | Pre-dose (0 hour) to 120 hours post-dose | Area under the concentration versus time curve from zero to last data point divided by dose of sorafenib in plasma was measured. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |
| Total Body Clearance of Sorafenib Calculated After Extravascular Administration (CL/F) | Pre-dose (0 hour) to 120 hours post-dose | Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |
| Maximum Observed Drug Concentration After Single Dose Administration Divided by Dose (Cmax/D) of Sorafenib in Plasma | Pre-dose (0 hour) to 120 hours post-dose | Maximum observed drug concentration after single dose administration divided by dose of sorafenib in plasma was measured. Geometric mean and percentage geometric coefficient of variation (%CV) were reported. |

| Number of Subjects With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs) | From start of study treatment up to 30 days after the last sorafenib dose administration | An adverse event (AE) was any untoward medical occurrence in subject who received study drug without regard to possibility of causal relationship. AEs that started or worsened after first administration of study medication up to 30 days after end of treatment with study medication were considered to be treatment-emergent (TE). A serious adverse event (SAE) was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly and another medical important serious event as judged by investigator. SAEs that started or worsened after study drug treatment were recorded as TESAEs. |
| Number of Subjects With Various Acceptance Regarding the Taste and Palatability of the Tablet Formulations | Within 5 to 10 min of each administration of sorafenib | For each administration of sorafenib, subjects completed a questionnaire regarding the taste and palatability of the tablets for oral suspension or marketed tablets within 5 to 10 min after administration. Results from the questionnaire regarding the taste of tablet, aftertaste and overall impression of the two different tablet formulations were analysed. CD= Completely disagree; SD= Somewhat disagree; Ne= Neutral; SA= Somewhat agree; CA= Completely agree; Un= Unknown. |
| Time to Reach Maximum Concentration (tmax) of Sorafenib in Plasma | Pre-dose (0 hour) to 120 hours post-dose | Time to reach maximum concentration of sorafenib in plasma. |
