Outcome Measures

Primary Outcomes (1)

  • Quantity of BCG at challenge site

    To evaluate and compare the amount of BCG (measured by CFU count and PCR) from a biopsy taken from the intradermal BCG challenge site in healthy BCG-naïve adults receiving either BCG SSI or BCG Tice at either standard or high dose

    At Day 14

Secondary Outcomes (1)

  • Immune response markers

    Up to Day 14

Other Outcomes (2)

  • Local and systemic adverse events

    Up to Day 28

  • Mycobacterial Growth Inhibition Assays

    Up to day 14

Study Arms (5)

Group A

EXPERIMENTAL

10 BCG-naïve subjects receiving intradermal BCG SSI at standard dose (2-8 x 10\^5 cfu) followed by a punch biopsy at the challenge site 14 days later.

Drug: BCG SSI

Group B

EXPERIMENTAL

10 BCG-naïve subjects receiving BCG Tice at standard dose (2-8 x 10\^5 cfu) followed by a punch biopsy at the challenge site 14 days later.

Drug: BCG Tice

Group C

EXPERIMENTAL

10 BCG-naïve subjects receiving intradermal BCG SSI at high dose (6-24 x 10\^5 cfu) followed by a punch biopsy at the challenge site 14 days later.

Drug: BCG SSI

Group D

EXPERIMENTAL

10 BCG-naïve subjects receiving intradermal BCG Tice at high dose (6-24 x 10\^5 cfu) followed by a punch biopsy at the challenge site 14 days later.

Drug: BCG Tice

Group E

EXPERIMENTAL

8-12 BCG-naïve subjects receiving the optimal strain and dose of intradermal BCG identified from preliminary results obtained from Group A, B, C and D, followed by a punch biopsy at the challenge site 14 days later.

Drug: BCG SSIDrug: BCG Tice

  • Resident in or near Oxford (for CCTVM) or Birmingham (for WTCRF) for the duration of the study period
  • No relevant findings in medical history or on physical examination
  • Allow the Investigators to discuss the volunteer's medical history with their GP
  • Use effective contraception for the duration of the study period (females only)
  • Agreement to refrain from blood donation during the duration of the study
  • Give written informed consent
  • Allow the Investigator to register volunteer details with a confidential database to prevent concurrent entry into clinical trials
  • Able and willing (in the Investigator's opinion) to comply with all the study requirements

You may not qualify if:

  • Clinically significant history of skin disorder, allergy, immunodeficiency (including HIV), cancer (except BCC or CIS), cardiovascular disease, respiratory disease, gastrointestinal disease, liver disease, renal disease, endocrine disorder, neurological illness, psychiatric disorder, drug or alcohol abuse
  • History of serious psychiatric condition
  • Concurrent oral or systemic steroid medication or the concurrent use of other immunosuppressive agents
  • History of anaphylaxis to vaccination or any allergy likely to be exacerbated by any component of the challenge agent
  • Any abnormality of screening blood or urine tests that is deemed to be clinically significant or that may compromise the safety of the volunteer in the study
  • Positive HBsAg, HCV or HIV antibodies
  • Female confirmed pregnant or intention to become pregnant during study period, or currently lactating
  • Current involvement in another trial that involves regular blood tests or an investigational medicinal product
  • Use of an investigational medicinal product or non-registered drug, live vaccine, or investigational medical device for four weeks prior to dosing with the study challenge agent
  • Administration of immunoglobulins and/or any blood products within the three months preceding the planned challenge date
  • +1 more criteria
