Site monitoring will be conducted to ensure that human subject protection, study procedures, laboratory procedures, study intervention administration, and data collection processes are of high quality and meet the sponsor, the sites, and regulatory guidelines and that the study is conducted in accordance...
The PPD test involves an intradermal injection of 5 units of PPD (0.1 mL), preferably with a 26-, 27-, or 30-gauge needle. The results should be read between 48 and 72 hours after administration. In immunologically intact individuals, induration of less than 5 mm constitutes a negative re...
In the previous pharmacokinetic study of TB47, the maximum blood concentration (Cmax) of TB47 in mice could reach 0.63 ± 0.28 μg/mL and its t1/2 was 35.6 ± 2.7 h after oral administration of 10 mg/kg TB47. In addition, the concentrations in mouse foot tissue within 48 h were >...

Pharmacokinetic parameters of TB47 in BALB/c mice are summarized in Table2. After intravenous administration of 2 mg kg−1TB47, the AUC (0–t) andt1/2were 10,409 ± 139 μg L−1 × hand 17.7 ± 2.6 h, respectively. Whereas the AUC (0–t),Cmaxandt1...
Today, the WHO recognizes the importance that any new TB vaccine designed for administration at birth, should show similar non-specific benefits as BCG vía mechanisms of trainned immunity and/or cross-reactivity of adaptive immunine responses to other pathogens. Following the footsteps of BCG’s ...
RESULTS. Administration of the high-dose rifampin regimen achieved four times higher brain concentration than the standard-dose regimen and displayed higher bactericidal activity in both mice and rabbits (P < 0.01) (Fig. 2). There were no differences in intracerebral microglial activation (124I-DPA...
