Long-Term Follow-Up on a Cohort Temporary Utilization Authorization (ATU) Survey of Patients Treated with Pheburane (Sodium Phenylbutyrate) Taste-Masked Granules.

Objectives: The aim was to describe the status of patients with urea cycle disorders (UCD) at the latest long-term clinical follow-up of treatment with a new taste-masked formulation of sodium phenylbutyrate (NaPB) granules (Pheburane). These patients are a subset of those treated under a cohort temporary utilisation study (ATU) previously reported and now followed for 2 years.

Methods: From a French cohort temporary utilization authorization (ATU) set up to monitor the use of Pheburane on a named-patient basis in UCD patients in advance of its marketing authorization, a subset of patients were followed up in the long term.

French Nationwide Cohort Temporary Utilization Authorization Survey of GranuPAS(®) in MDR-TB patients.

Background: Para-aminosalicylic acid (PAS) is again needed for the treatment of multidrug and extensively drug-resistant tuberculosis (M/XDR-TB). The study of a new granulated formulation (PAS-GR, 'GranuPAS(®)'), which might have fewer adverse events, was made possible by the statutory requirement that data be collected regarding its use in France in multidrug-resistant TB (MDR-TB) patients under a 'therapeutic utilization' follow-up for safety and efficacy system called 'Autorisation Temporaire d'Utilisation' (ATU).

Methods: In May 2011 an ATU cohort was established to monitor the named patient use of PAS-GR.

Results from a Nationwide Cohort Temporary Utilization Authorization (ATU) survey of patients in france treated with Pheburane(®) (Sodium Phenylbutyrate) taste-masked granules.

Objectives: The aim of this study was to describe a nationwide system for pre-marketing follow-up (cohort temporary utilization authorization [ATU] protocol; i.e., 'therapeutic utilization') of a new taste-masked formulation of sodium phenylbutyrate (NaPB) granules (Pheburane(®)) in France and to analyze safety and efficacy in this treated cohort of patients with urea cycle disease (UCD).

Dose regimen of para-aminosalicylic acid gastro-resistant formulation (PAS-GR) in multidrug-resistant tuberculosis.

Background And Objectives: Resurgence of multidrug-resistant tuberculosis (MDR-TB) has raised a renewed interest in para-aminosalicylic acid (PAS) and other efficacious drugs. A gastro-resistant granule formulation (PAS-GR) was designed to be better tolerated than earlier forms of PAS, with fewer adverse effects from reduced production of meta-aminophenol. PAS release from PAS-GR granules is slower than with earlier formulations.
