A Study to Investigate the Pharmacokinetics (PK) of Modified Release (MR) Prototype Coated Tablet Formulations of GSK2982772

GlaxoSmithKline33 enrolled

Overview

Previous clinical studies of immediate release (IR) formulations of GSK2982772 resulted in a high peak to trough ratio of GSK2982772. Additionally, the short half-life for GSK2982772 (approximately 2 to 3 hours) necessitates twice a daily (BID) or thrice daily (TID) dosing of an IR formulation. As a result, MR formulations using a polymer matrix approach with minitablets in capsule and MR tablet formulations were investigated. The emerging PK data of the MR formulations investigated to date have demonstrated that a once daily (QD) PK profile can be achieved in the fasted state but the polymer matrix formulation is susceptible to food effects when administered with a high fat breakfast. The purpose of this study is to evaluate MR prototype coated tablet formulations. This study will evaluate the PK of MR prototype coated tablet formulations of GSK2982772. The study is divided into two parts; Part A and Part B. The MR tablet coating used in Part A and the initial periods of Part B will have an aperture drilled into the enteric coating of either side of the tablet. This allows some drug release to commence in the stomach whilst providing controlled release throughout the gastrointestinal (GI) tract. In Part B only, a new investigational medicinal product (IMP) will be manufactured to allow comparison of the tablet coating either with apertures (i.e., drilled) or without apertures (i.e., full coat/non drilled). Part A will be a 6-period, 6-way fixed sequence design, up to 4 MR tablet prototype coated formulations will be evaluated in fasted state at 240 milligrams (mg). Periods 1, 2 and 3 will evaluate MR1, IR tablet and MR2 respectively. Periods 4, 5 and 6 will be flexible and the dosing regimen will be dependent on the outcome of Periods 1 to 3. In addition, the impact of food (high fat meal, standard breakfast or administration 30 or 60 minutes before a standard breakfast) on selected MR prototype coated tablet formulations may also be evaluated in Period 4, 5 or 6 of Part A. Each inpatient period for MR regimens (Periods 1, 3, 4 to 6) will consist of 4 days and 3 nights, and the inpatient period for the IR tablet (Period 2) will consist of 3 days and 2 nights. There will be a minimum washout of 7 days between doses, and a follow-up visit will occur at 7 to 9 days after the last study treatment. The Part B of the study will be a 7-period fixed sequence which will evaluate the selected MR prototype coated tablet formulation(s) at different tablet strengths or as multiple unit doses and with or without apertures in the tablet coatings. There will be an interim review after each period 1 to 5 of Part B to select the dose level, formulation and prandial status for each subsequent period. An interim data review after Part B Period 6 will determine if optional Period 7 is required and the dose level, dosing time (morning or evening), formulation and prandial status for that period. Each inpatient period will consist of a 4-day and 3-night with a minimum of 7 days washout between doses. A follow-up visit will occur at 7 to 9 days after the last study treatment. Approximately 33 subjects will be enrolled in the study. The total duration for Part A will be approximately 10-12 weeks and 10-14 weeks for Part B (including screening period of approximately 4 weeks).

Time frame: Pre-dose, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 36 and 48 hours post-dose

Part A: Frelformulation Based on AUC (0-t) of GSK2982772 for MR Coated Tablet Formulation (240 mg)

Blood samples were collected at indicated time points for analysis of Frelformulation based on AUC of GSK2982772 in fasted state. Frel for AUC (0-t) was calculated as Geometric mean of AUC(0-t) of MR Fasted formulation (test) / Geometric mean of AUC(0-t) of Fasted of IR Formulation (reference) multiplied by 100.

Time frame: Pre-dose, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 36 and 48 hours

Part A: Frelformulation Based on AUC(0-24) of GSK2982772 for MR Coated Tablet Formulation (240 mg)

Blood samples were collected at indicated time points for analysis of Frelformulation based on AUC of GSK2982772 in fasted state. Frel for AUC(0-24) was calculated as Geometric mean of AUC(0-24) of MR Fasted formulation (test) / Geometric mean of AUC(0-24) of Fasted of IR Formulation (reference) multiplied by 100.

Time frame: Pre-dose, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 hours

Part A: Frelformulation Based on Cmax of GSK2982772 for MR Coated Tablet Formulation (240 mg)

Blood samples were collected at indicated time points for analysis of Frelformulation based on Cmax of GSK2982772 in fasted state. Frel for Cmax was calculated as Geometric mean of Cmax of MR Fasted formulation (test) / Geometric mean of Cmax of Fasted Formulation of IR formulation (reference) multiplied by 100.

Time frame: Pre-dose, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 36 and 48 hours

Secondary Outcomes

Part A: Number of Participants With Any Adverse Events (AEs) and Serious Adverse Events (SAEs)

An AE is any untoward medical occurrence in a clinical study participants, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. A SAE is defined as any untoward medical occurrence that at any dose may result in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly or birth defect and important medical events that may jeopardize the participants or may require medical or surgical intervention to prevent one of the other outcomes listed before.

Time frame: Up to Day 67

Part A: Number of Participants With Emergent Clinical Chemistry Results by Potential Clinical Importance (PCI) Criteria

Clinical chemistry parameters with PCI values:albumin (low: \<30 millimoles per liter\[mmol/L\]), Alanine transaminase (ALT) (high: \>=2xupper limit of normal \[ULN\]), Aspartate Aminotransferase(AST) (high: \>=2xULN), Alkaline phosphatase(ALP) (high:\>=2xULN), calcium(low: \<2 mmol/L, high: \>2.75 mmol/L),creatinine (high: \>44.2 mmol/L),glucose (low: \<3 mmol/L,high: \>9 mmol/L), potassium (low: \<3 mmol/L,high: \>5.5 mmol/L),sodium (low: \<130 mmol/L,high: \>150 mmol/L),total bilirubin(high :\>= 1.5xULN). Participants are counted in the worst case category that their value changes to (Low, Normal or High), unless there is no change in their category. Participants whose value category was unchanged (e.g., High to High),or whose value became normal, are recorded in the "To Normal or No Change" category. Participants are counted twice if the participants has values that changed 'To Low' and 'To High', so the percentages may not add to 100%. Data for worst-case post-Baseline has been reported.

Time frame: Up to Day 67

Part A: Number of Participants With Emergent Hematology Results by Potential Clinical Importance Criteria

Hematology parameters with PCI ranges: hematocrit (high: \>0.54 percentage of red blood cells), hemoglobin (high: \>180 grams per liter \[g/L\]), lymphocytes (low: \<0.8\*giga cells per liter \[10\^9/L\]), total neutrophil count (low: \<1.5\*10\^9/L), platelet count (low: \<100\*10\^9/L and high: \>550\*10\^9/L), and while blood cell (WBC) count (low: \<3\*10\^9/L and high: \>20\*10\^9/L). Participants are counted in the worst case category that their value changes to (Low, Normal or High), unless there is no change in their category. Participants whose value category was unchanged (e.g., High to High), or whose value became normal, are recorded in the "To Normal or No Change" category. Participants are counted twice if the subject has values that changed 'To Low' and 'To High', so the percentages may not add to 100%. Data for worst-case post-Baseline has been reported.
