Evaluating the Pharmacokinetic Parameters and Relative Bioavailability of Sorafenib (XS005) in Healthy Male Subjects

Xspray Pharma AB15 enrolled

Overview

This is a single centre, open-label, randomised, single dose, 3-way crossover comparative (PK) and bioavailability study in healthy male subjects comparing a 200 mg Sorafenib (Nexavar®) reference tablet (Regimen A) to XS005 Sorafenib Capsule A, 2 x 50 mg (Regimen B) and XS005 Sorafenib Tablet A,100 mg (Regimen C) formulation. It is planned to enroll 15 subjects who will receive single oral doses of investigational medicinal product (IMP) across 3 treatment periods.

Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results. 13. History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or gastrointestinal disease, neurological or psychiatric disorder, as judged by the investigator. 14. Subject has a QT interval corrected by Fredericia (QTcF) \>450 ms based on ECG at screening or at pre-dose Period 1 or a history of additional risk factors for Torsades de Pointe (eg hypokalaemia, hypomagnesia, a family history of long QT syndrome). 15. Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients. 16. Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hayfever is allowed unless it is active. 17. Donation or loss of greater than 400 mL of blood within the previous 3 months. 18. Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than 4 g per day paracetamol) or herbal remedies in the 14 days before IMP administration. Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor. 19. Subjects with pregnant partners. 20. Failure to satisfy the investigator of fitness to participate for any other reason.

Outcomes

Primary Outcomes

Time of Maximum Observed Plasma Concentration (Tmax) of XS005 and Nexavar®

The pharmacokinetic parameters (Tmax) were determined for the test and reference products (XS005 Sorafenib Capsule A, 2 x 50 mg and XS005 Tablet A, 100 mg and reference Sorafenib tablets (Nexavar®), respectively) for each subject using non-compartmental methods.

Time frame: For each study period, blood samples collected at 15 time points (including pre-dose) during the study period on Day 1 and Day 4.

Maximum Observed Plasma Concentration (Cmax) of XS005 and Nexavar®

The pharmacokinetic parameters (Cmax) were determined for the test and reference products (XS005 Sorafenib Capsule A, 2 x 50 mg and XS005 Tablet A, 100 mg and reference Sorafenib tablets (Nexavar®), respectively) for each subject using non-compartmental methods.

Time frame: For each study period, blood samples collected at 15 time points (including pre-dose) during the study period on Day 1 and Day 4.

Area Under the Plasma Concentration-Time Curve from 0 time to the last measurable of concentration AUC(0-last) of XS005 and Nexavar®
