New live mycobacterial vaccines: the Geneva consensus on essential steps towards clinical development.

As the disease caused by Mycobacterium tuberculosis continues to be a burden, which the world continues to suffer, there is a concerted effort to find new vaccines to combat this problem. Of the various vaccines strategies, one viable option is the development of live mycobacterial vaccines. A meeting with researchers, regulatory bodies, vaccines developers and manufactures was held to consider the challenges and progress, which has been achieved with live mycobacterial vaccines (either modified BCG or attenuated M.

Advancing TB vaccines to Phase I clinical trials in the US: regulatory/manufacturing/licensing issues.

This article discusses the steps required to file an investigational new drug (IND) application to the United States Food and Drug Administration (FDA) and begin a Phase I trial of a new tuberculosis vaccine in the US. Many different groups play a role in bringing a new vaccine to market. But it is the researcher who begins the process by converting an idea into a new vaccine construct.

A novel approach to develop anti-HIV drugs: adapting non-nucleoside anticancer chemotherapeutics.

Some anticancer drugs, but not all, inhibit replication of human immunodeficiency virus (HIV) and thus, exhibit a therapeutic potential. Such drugs, unlike the traditional HIV enzyme inhibitors, could suppress HIV strains that are resistant to inhibitors of viral enzymes, decrease proviral burden in vivo, or reduce reservoirs of infection via killing infected cells. Thus, they may be an effective adjunct therapy or perhaps result in a cure.

Inhibition of HIV replication by immunoliposomal antisense oligonucleotide.

The sequence-specific suppression of HIV-1 replication using CD4 monoclonal-antibody-targeted liposomes, containing Rev antisense phosphorothioate oligonucleotides is described. Liposomes were prepared by encapsulating the 20-mer antisense DNA sequence of the rev HIV-1 regulatory gene, in the form of a phosphorothioate oligonucleotide. Specific targeting was accomplished by conjugating anti-CD4 mouse monoclonal antibody to the surface of the liposomes.
