Nutri Pharma's Vacc-C5 to be prepared for phase I/II clinical trial
Research results to date indicate that Vacc-C5 may induce a protective antibody response in HIV patients similar to that found in patients with a very slow or non-progressing disease. This naturally very slow or non-progressing HIV infection observed in a small minority of patients has been the subject of academic interest for years and our discovery of these antibodies in such patients could lead to a significant shift in the approach to treating HIV. The results have been presented to the company's Clinical Advisory Board with very encouraging feedback, says Birger Sørensen, CEO of Bionor Immuno.
The main trigger behind the disease progression from HIV to AIDS is the hyper-activation of the immune system. This hyper-activation overwhelms and gradually causes a collapse in the immune system, leading to the AIDS stage of the disease.
From research on blood donated by patients with a very slow or non-progressing HIV disease, the company has succeeded in identifying a specific part of the virus, C5, which is believed to induce hyper-activation of the immune system. Antibodies to this specific part are likely to be protective and cause a slow disease progression. Using its unique technology, the company has developed the vaccine candidate Vacc-C5, that is designed to induce a similar antibody response to the one discovered in patients with naturally very slow disease progression. Vacc-C5 has passed pre-clinical research tests showing that it has the potential to induce the desired antibodies.
The antibodies induced by Vacc-C5 are expected to be beneficial at all stages of HIV disease and produce a dual effect; i) slowing down or halting the disease progression and ii) significantly reducing the production of virus. It is believed that the combination of Vacc-C5 together with Vacc-4x, the company's most advanced vaccine candidate (currently in phase II placebo controlled international multicenter trial with 135 patients enrolled; results expected in October 2010), could form a potent preventative HIV vaccine.
As part of the preparations for a Phase I/II clinical trial to be initiated in 2011, the company will carry out routine toxicity tests, to ensure the safety of the Vacc-C5 components. The toxicology program is planned to be completed by Q2, 2011.

Antibodies are specialized molecules of our immune system that can specifically recognize and neutralize pathogens or foreign substances. Antibody research in biotech and pharma has recognized this natural defense potential and is working intensively to make it therapeutically useful. From monoclonal antibodies used against cancer or autoimmune diseases to antibody-drug conjugates that specifically transport drugs to disease cells - the possibilities are enormous
