Brief Summary:
This is a Phase 1, randomized, controlled, double-blind, multiple-dose, dose-ranging study of DAR 901, (an inactivated whole cell mycobacterial vaccine) to be conducted in HIV negative and HIV positive adults previously vaccinated with BCG. The goals of the trial are to determine the safety, tolerability, and immunogenicity of multiple doses of the vaccine at different dose levels, ranging from 0.1 to 1 mg.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 59 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Phase 1, Randomized, Placebo-Controlled, Double-Blind, Multiple-Dose, Dose-Ranging Study of the Safety and Immunogenicity of DAR-901, a Killed, Non-Tuberculous Mycobacterial Vaccine, in HIV-negative and HIV-positive Adults Who Have Previously Received BCG

Arm Intervention/treatment
Experimental: DAR-901

Intradermal administration at 0, 2 and 4 months

Three dose groups in dose escalation: 0.1 mg, 0.3 mg and 1.0 mg, all constituted in 0.1 mL

Biological: DAR-901
Active Comparator: BCG
Intradermal injection of 0.1 mL saline at 0 mos, 2 mos, intradermal injection of 0.1 mL BCG at 4 mos
Biological: BCG
Placebo Comparator: Sterile saline
Intradermal injection of 0.1 mL sterile saline at 0, 2 and 4 mos

Primary Outcome Measures :
  1. Safety [ Time Frame: 10 months ]
    Subjects will be followed for both systemic side effects and injection site reactions


Secondary Outcome Measures :
  1. Immunogenicity [ Time Frame: 10 months ]
    Cellular and humoral responses to the vaccine antigen will be tested at baseline and after each of 3 doses of vaccine
