A Safety and Immunogenicity Trial With an Adjuvanted Tuberculosis(TB) Subunit Vaccine (THYB-01)

January 18, 2013 updated by: Statens Serum Institut

A Safety and Immunogenicity Phase 1 Trial With an Adjuvanted TB Subunit Vaccine (Ag85B-ESAT-6 + IC31) Administered at 0 and 2 Months

The purpose of this study is to evaluate the safety profile of an adjuvanted TB subunit vaccine administered at 0 and 2 months in healthy BCG-unvaccinated volunteers with no prior history of TB disease or known prior exposure to TB

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Antigen group + high adjuvans

Biological: 50 microgram antigen (Ag85B + ESAT-6) + 500 nmol KLK + 20 nmol ODN1a
0.5 mL suspension for injection x 2 with 2 months interval
Other Names:
  • Antigen H1 + IC31
Experimental: Antigen group
The antigen group received two injections of antigen (Ag85B + ESAT-6) two months apart.
Biological: 50 microgram antigen (Ag85B + ESAT-6)
0.5 mL suspension for injection x 2 with 2 months interval
Other Names:
  • Antigen H1
Experimental: Antigen + low adjuvans group
The antigen group + low adjuvans group received two injections of antigen (Ag85B + ESAT-6) + IC31 (100 nmol KLK + 4 nmol ODN1a) two months apart.
Biological: 50 microgram antigen (Ag85B + ESAT-6) + 100 nmol KLK + 4 nmol ODN1a
0.5 mL suspension for injection x 2 with 2 months interval
