Phase I crossover study of DNA-protein kinase inhibitor peposertib in healthy volunteers: Effect of food and pharmacokinetics of an oral suspension.

Peposertib is an orally administered inhibitor of DNA-dependent protein kinase. We evaluated the effect of food on its pharmacokinetics, and examined the pharmacokinetics of an oral suspension (OS) of disintegrated tablets, in a phase I, open-label, crossover three-period study (NCT04702698). Twelve healthy volunteers were randomized to one of six treatment sequences.

Thorough QT/QTc Study Evaluating the Effect of Macimorelin on Cardiac Safety Parameters in Healthy Participants.

Macimorelin is an orally active growth hormone secretagogue indicated for the diagnosis of adult growth hormone deficiency. The primary objective of this study was to evaluate the effect of macimorelin on the baseline and placebo-corrected mean QT interval using Fridericia's formula (ΔΔQTcF). Secondary objectives were to determine QTcF for moxifloxacin; evaluate the effects of macimorelin on other cardiac intervals (PR, QRS, RR), heart rate, and electrocardiogram morphology parameters; characterize pharmacokinetics; and assess safety of macimorelin.

No Clinically Relevant Interactions of St. John's Wort Extract Ze 117 Low in Hyperforin With Cytochrome P450 Enzymes and P-glycoprotein.

Hypericum perforatum L. (St. John's wort) is used to treat mild-to-moderate depression.

EE-drospirenone-levomefolate calcium versus EE-drospirenone + folic acid: folate status during 24 weeks of treatment and over 20 weeks following treatment cessation.

Background: Adequate folate supplementation in the periconceptional phase is recommended to reduce the risk of neural tube defects. Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to sustainable improvements in folate status compared with an oral contraceptive + folic acid.

Absolute Bioavailability and Effect of Food on the Disposition of Safinamide Immediate Release Tablets in Healthy Adult Subjects.

The objectives of this study were to establish the basic intravenous (IV) single-dose PK of safinamide and its major human metabolites, the absolute bioavailability (BA) and food effect on safinamide tablets. Fourteen healthy adult male and female subjects received 50 mg safinamide single-dose treatments according to a randomized, 3-period, 2-sequence crossover design: immediate release (IR) tablets, administered after an overnight fast and after a standardized high-fat, high-calorie breakfast, and IV solution, administered over 30 minutes. Treatments were separated by wash-out intervals of at least 17 days.

Comparison of the pharmacokinetic and pharmacodynamic profiles of one US-marketed and two European-marketed epoetin alfas: a randomized prospective study.

Background: HX575, licensed under the brand names Binocrit®, Epoetin Alfa Hexal®, and Abseamed®, was approved in 2007 as the first biosimilar recombinant human erythropoietin alfa (epoetin alfa) in the EU using Erypo®/Eprex® as reference product.

Objectives: The aim of this study was to investigate the bioequivalence and potency of registered epoetin alfa products that have not been compared before in a randomized controlled clinical study.

Methods: The study was conducted in two parts: part A compared the European-marketed HX575 and the US-marketed Epogen®; part B compared the European-marketed Erypo®/Eprex® and HX575 manufactured at two different drug substance production sites (HX575-TT denoting the already-approved technology-transfer product from an additional manufacturing site).

Pharmacokinetic comparison of an oral diclofenac potassium liquid-filled soft gelatin capsule with a diclofenac potassium tablet.

Objective: To compare the pharmacokinetic profiles of diclofenac potassium liquid-filled soft gelatin capsules (DPSGC) using patented ProSorb dispersion technology with an immediate-release, diclofenac potassium 50-mg comparator tablet in two open-label, single-dose, randomized, crossover relative bioavailability studies in healthy volunteers.

Methods: In Study 1, volunteers (n = 21) received DPSGC 50 mg or a diclofenac potassium 50-mg comparator tablet in two inpatient study periods. In Study 2 (n = 54), volunteers received DPSGC 25 mg, DPSGC 50 mg, or a diclofenac potassium 50-mg comparator immediate-release tablet in three inpatient study periods.

Single-dose pharmacokinetic study of rapidly dispersing diclofenac potassium formulations in healthy volunteers.

Objective: The clinical utility of diclofenac potassium, a commonly prescribed analgesic that provides mild to moderate pain relief, may be hindered by its delayed, depressed, and/or inconsistent absorption characteristics. A diclofenac potassium formulation using proprietary dispersion technology (ProSorb) was developed to overcome these limitations. The authors evaluated and compared the pharmacokinetics (PK) of 2 investigational diclofenac potassium liquid filled soft gelatin capsule (DPSGC) preparations and one investigational diclofenac liquid formulation, each incorporating the proprietary dispersion technology, to establish bioequivalence and identify a formulation for further clinical study.
