Intercell provides update on ongoing Phase II vaccine studies
Pseudomonas vaccine: Study in intensive care patients to investigate immunogenicity and safety of a Pseudomonas aeruginosa vaccine and to assess Pseudomonas infection rates
In the Phase II clinical trial, mechanically ventilated intensive care patients are vaccinated with Intercell's prophylactic Pseudomonas aeruginosa vaccine. These patients are at a particularly high risk of acquiring severe and often life-threatening forms of Pseudomonas aeruginosa infections, such as ventilator-associated Pneumonia, Sepsis or soft tissue infection. Two different dosages of alum-adjuvanted vaccine and one formulation without adjuvant are used in the placebo-controlled trial.
The interim analysis from 225 out of 400 total patients to be vaccinated in this study has shown good safety and tolerability of the vaccine. In addition, robust immunogenicity by antibody induction which were assessed by standard and avidity IgG ELISA and functional opsonization assays could be shown. Functional antibodies are expected to be the major protective mechanism against Pseudomonas aeruginosa infections. Immune responses and safety data observed in intensive care patients appear largely comparable to results from a preceding Phase I trial in healthy volunteers. Based on these interim data an independent Safety Board recommended the continuation of the study. Meanwhile, the trial is fully enrolled, having achieved recruitment of 400 patients in more than 40 intensive care units in nine countries in Europe and Latin America.

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
