A Safety and Dose Finding Trial of C-Tb, When Given to Adult Patients Recently Diagnosed With Active Tuberculosis

2014-08-27 03:17:12 | BioPortfolio

Summary

The primary objective is to assess the safety of two doses of C-Tb (0.01 and 0.1 µg/0.1 mL) when administered intradermally by the Mantoux technique to patients in the acute phase of treatment against active TB. The secondary objectives are to assess the immune response of two doses (0.01 and 0.1 µg/0.1 mL) of C-Tb from the size of induration and to assess the safety of unpreserved C-Tb and C-Tb preserved with 0.5% phenol (local reactions).

Description

This clinical trial is a single centre phase Ib open dose adjustment study with respect to the dose of C-Tb combined with a double blind randomised, split-body comparison of unpreserved C-Tb and C-Tb preserved with 0.5% phenol (each patient receives the unpreserved version in one arm and the preserved version in the other arm).

Medical and Biotech [MESH] Definitions

The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.

Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)

Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.

TUBERCULOSIS that involves any region of the GASTROINTESTINAL TRACT, mostly in the distal ILEUM and the CECUM. In most cases, MYCOBACTERIUM TUBERCULOSIS is the pathogen. Clinical features include ABDOMINAL PAIN; FEVER; and palpable mass in the ileocecal area.

Tuberculosis of the mouth, tongue, and salivary glands.
