  • To compare the size of induration of C-Tb and PPD RT 23 if injected alone or concomitantly in Tuberculosis infected patients (HIV positives and HIV negatives) [ Time Frame: Onset from the injection(s) to 28 days after the injections ] [ Designated as safety issue: No ]
  • To assess if concomitant injections of C-Tb and PPD RT 23 influence the tests abilities to identify positive results of Tuberculosis in Tuberculosis infected patients [ Time Frame: Onset from the injection(s) to 28 days after the injections ] [ Designated as safety issue: No ]

  • To compare the C-Tb test's ability to identify positive results in Tuberculosis infected patients with the in vitro QuantiFERON®TB Gold In Tube assay in blood collected immediately before application of the C-Tb skin test [ Time Frame: Onset from the injection(s) to 28 days after the injections ] [ Designated as safety issue: No ]
  • To compare the C-Tb test's ability to identify positive results in Tuberculosis infected patients with the PPD RT 23 test [ Time Frame: Onset from the injection(s) to 28 days after the injections ] [ Designated as safety issue: No ]
  • To assess the safety of C-Tb skin test by investigating laboratory safety parameters and assessing all adverse events (local and systemic) occurring within 28 days after administration of the C-Tb and/or PPD RT 23 tests [ Time Frame: Onset from the injection(s) to 28 days after the injections ] [ Designated as safety issue: Yes ]

Safety Study Investigating if Concomitant Injections of C-Tb and 2 T.U Tuberculin Affect Induration Responses
A Phase II/III Trial Investigating if Concomitant Injections of the Diagnostic Agents C-Tb and 2 T.U Tuberculin PPD RT 23 SSI Affect the Induration Responses in Combination With a Safety Assessment of C-Tb

A new, more specific skin test to detect tuberculosis has been developed by Statens Serum Institut in Denmark. The new skin test is named C-Tb and like the current Tuberculin a positive test result will show as redness and/or induration at the injection site, while a negative test will leave no reactions.

The aim of this study is to address if the size of induration and the sensitivity of C-Tb is influenced by concomitant injections of C-Tb and Tuberculin. Furthermore, the intention is to evaluate the safety of C-Tb when injected alone or concomitantly with Tuberculin.

The TESEC-07 trial is a GCP double blind randomised controlled phase II/III trial investigating if concomitant injections of the diagnostic agents C-Tb and 2 T.U Tuberculin PPD RT 23 SSI affect the induration responses in combination with a safety assessment of C-Tb. TESEC-07 is a multi-centre trial and will be conducted in South Africa in patients recently diagnosed with TB comprising 360 HIV negative and 90 HIV positive adults allocated to 3 trial groups.

  • A within group paired comparison of 0.1 μg/0.1 mL C-Tb and PPD RT 23 in 150 TB patients. The C-Tb and PPD RT 23 agents are given concomitantly to each volunteer in the RIGHT AND LEFT forearms according to a randomisation scheme.
  • A group of 150 TB patients will only receive the C-Tb agent randomised to either RIGHT or LEFT forearm.
  • A group of 150 TB patients will only receive the reference agent PPD RT 23 randomised to either RIGHT or LEFT forearm.
