1 TB VACCINES PIPELINE Working Group on New TB Vaccines September 2008 According to the Global Plan to Stop TB, 2006-2015, the introduction of new, effective TB vaccines will be an essential component of any strategy to eliminate TB by 2050. New TB vaccines to prevent childhood and adult forms of TB, to prevent progression of latent infection to active disease and to shorten drug treatment regimens or reduce the risk of relapse can fundamentally alter our approach to TB control. It is anticipated that the new generation of TB vaccines will work best using a heterologous prime- boost strategy to strengthen the immune response induced by the current BCG. This “prime- boost” strategy would include administration of BCG or, for example, a new recombinant BCG (rBCG), the “prime”, followed by a “booster” inoculation with a different vaccine to infants and young children before they are exposed to TB, or as a separate booster to young adults, or as an adjunct to chemotherapy. TB vaccines under development could work in several ways: 1) Prevent infection 2) Prevent primary disease 3) Prevent latent infection 4) Prevent reactivation of latent infection 5) Shorten the course and improve the response to chemotherapy The following is a list of TB vaccines under development presented in the following categories, with some candidates falling into more than one category: Priming: Vaccine candidates that would serve as the “prime” in a prime-boost regimen and intended to prevent TB. Boosting: Vaccine candidates that would serve as the “boost” in a prime-boost regimen and intended to prevent TB. Immunotherapy: Vaccines candidates that could be administered after a person has been exposed to M.tb to prevent reactivation or progression to TB disease and/or to shorten or improve the response to chemotherapy. Vaccine candidates are further divided into those that were, are, or will be in Phase I clinical development by the end of 2009, and those that are still in preclinical development with an anticipated entry into clinical development in 2010 or after. Vaccines intended for veterinary use are not included in this document. The information contained here was provided by the vaccine developers, unless otherwise indicated and includes updates for 2008. The asterisk (*) indicates that the information is the same as that presented in the previous Pipeline Report and no update was provided for this report. This TB Vaccines Pipeline document presents those products in development that have been brought to the attention of the working groups. The timelines given are those provided by the sponsor and are dependent upon progress in preclinical and clinical studies. Please note that no standard evaluation criteria have been applied for inclusion in this TB Vaccines Pipeline document. The list will be revised periodically and updated versions will be published annually through the Retooling and working groups’ websites.

j. Attenuated Live Vaccine based on PhoP Type of product: Live Vaccine based on rational attenuation of M. tuberculosis with the goal to replace BCG. A new generation vaccine has been constructed based on two independent genetic deletions without antibiotic markers. Sponsors: Candidate vaccines based on M. tuberculosis phoP mutants were developed in Carlos Martin’s laboratory at the University of Zaragoza in collaboration with Brigitte Gicquel’s laboratory at the Pasteur Institute in Paris, with national funds from Spain and France and with funds from the European Commission. Vaccine GMP production is sponsored by Genoma España. Product description: Live vaccine based on rational attenuation of M. tuberculosis by inactivation of phoP, a positive regulator of virulence genes. The vaccine candidate was tested for protection and safety in different animal models. Recently, following the Geneva Consensus for new live vaccines, two non-reverting genetic deletions, without presence of antibiotic markers, were genetically engineered for the final construct of MTBVAC. The deleted genes are involved in biosynthesis regulation of complex lipids implicated in M. tuberculosis virulence. Stage of development: Late pre-clinical testing and GMP production. Date of entry or expected date of entry into Phase I trials Late 2009-2010 Expected date for completion of Phase III trials: TBD

a. paBCG (pro-apoptotic BCG) Type of product Modified BCG with reduced activity of one or more anti-apoptotic microbial enzymes including iron co-factored superoxide dismutase (SodA), glutamine synthetase (GlnA1), thioredoxin, and thioredoxin reductase Sponsors The paBCG technology was developed in Doug Kernodle’s laboratory at Vanderbilt University Medical Center and the Nashville Veterans Affairs Medical Center with funding from the NIAID, NHLBI, and a 2002 VIP award from Sequella Global TB Foundation (now Aeras). The technology has been licensed by Aeras for further development. Product description Four immune-enhancing modifications have been introduced into BCG, alone and in combination. The modifications include: expression of dominant-negative SodA mutant; allelic inactivation of secA2 (by Miriam Braunstein at the University of North Carolina at Chapel Hill), elimination of diploid sigH, and expression of dominant-negative GlnA1 mutant. We constructed four 1st-generation vaccines with a single modification, six 2nd-generation vaccines with two modifications, four 3rd-generation vaccines with three modifications, and a single 4th-generation paBCG vaccine with all four modifications. Although intended primarily as priming, pre-exposure vaccines, the 3rd- and 4th-generation paBCG vaccines are cleared by the host after adaptive immunity develops and this enables boosting either with paBCG or the parent BCG vaccine to induce secondary responses. Stage of development Pre-clinical Date of entry or expected date of entry into Phase I trials Per Aeras, most likely in combination with other modifications to BCG. Expected date for completion of Phase III trials Per Aeras, most likely in combination with other modifications to BCG.
