The Africa non-communicable diseases (NCD) Open Lab: Impact of a portfolio of clinical studies to deepen the understanding of NCDs in sub-Saharan Africa.

Background: Clinical research in sub-Saharan Africa (SSA) has often focussed on communicable diseases. However, with the increasing burden of non-communicable diseases (NCDs), there is a need for Africa-specific NCD research.

Methods: GSK established the Africa NCD Open Lab in 2014.

First-in-human study of alpibectir (BVL-GSK098), a novel potent anti-TB drug.

Background: The clinical candidate alpibectir augments the activity of, and overcomes resistance to, the anti-TB drug ethionamide in vitro and in vivo.

Objectives: A Phase 1, double-blind, randomized, placebo-controlled study to investigate the safety, tolerability, pharmacokinetics (PK) and food effect of alpibectir administered as single and multiple oral doses in healthy volunteers (NCT04654143).

Methods: Eighty participants were randomized.

Academia and industry agreement on a feasibility tool for first-time-in-human clinical trial units.

First-time-in-human (FTIH) trials are designed to generate information on the safety, tolerability, as well as the pharmacokinetic and pharmacodynamics profile of new drugs. To ensure the safety of participants, these trials need to be conducted at specifically equipped phase I clinical trial units (CTUs). In accordance with the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Guideline for Good Clinical Practice (GCP) and the European Union (EU) regulatory guidelines, one of the aims of the European Regime Accelerator for Tuberculosis (ERA4TB) project is to collaboratively create a feasibility tool, through a partnership between public and private entities, for the validation of CTUs selected to conduct FTIH trials.

A randomized, fixed-dose, dose-response study of ropinirole prolonged release in advanced Parkinson's disease.

Aim: This Phase IV, double-blind, randomized, parallel-group study characterized the dose-response and tolerability of fixed doses of ropinirole prolonged release (PR) in subjects with advanced Parkinson's disease.

Patients & Methods: Subjects receiving concomitant l-dopa received once-daily ropinirole PR 4, 8, 12, 16 or 24 mg, or placebo, up-titrated for 13 weeks, maintained for 4 weeks.

Results: At maintenance period week 4, ropinirole PR significantly reduced total awake 'Off-time' (16 mg; p = 0.

Human Kinetic Modeling of the 5HT6 PET Radioligand 11C-GSK215083 and Its Utility for Determining Occupancy at Both 5HT6 and 5HT2A Receptors by SB742457 as a Potential Therapeutic Mechanism of Action in Alzheimer Disease.

Unlabelled: Antagonism of 5-hydroxytrypamine-6 (5HT6) receptors is associated with procognitive effects in preclinical species, suggesting a therapeutic potential for this mechanism in Alzheimer disease (AD) and other cognitive diseases. In a phase 2 dose study, SB742457, a novel 5HT6 antagonist, showed increasing procognitive effects in patients with AD as the dose increased, with a procognitive signal in AD patients at a dose of 35 mg/d superior to the other doses tested (5 and 15 mg/d).

Methods: In this article, we describe the quantification and pharmacologic selectivity of a new 5HT6 PET ligand ((11)C-GSK215083) in healthy volunteers and its use to measure occupancies achieved at various doses of SB742457.

Gabapentin enacarbil and morphine administered in combination versus alone: a double-blind, randomized, pharmacokinetic, and tolerability comparison.

Purpose: Coadministration of morphine with oral gabapentin has been shown to increase plasma gabapentin concentrations. This study evaluated whether there was any interaction between gabapentin enacarbil (GEn), which is a prodrug of gabapentin, and morphine in terms of pharmacokinetics, pharmacodynamics, safety, and tolerability.

Methods: This randomized, double-blind, 3-treatment crossover study included nonelderly, healthy male subjects.

Cardiac repolarization with Gabapentin enacarbil in a randomized, double-blind, placebo- and active-controlled, crossover thorough QT/QTc study in healthy adults.

Background: Gabapentin enacarbil (GEn) is a prodrug of gabapentin and is approved in the United States in adults for the management of postherpetic neuralgia and in the United States and Japan for the treatment of moderate-to-severe primary restless legs syndrome.

Objective: This study examined the lack of effect of GEn on cardiac repolarization in accordance with International Conference on Harmonisation E14 guidance.

Methods: This was a randomized, double-blind, double-dummy, placebo- and active- controlled, crossover study in healthy adults (age range, 18-50 years).
