                   Xenova Initiates Second Clinical Trial for
                              Anti-Smoking Vaccine


Slough, UK, 8 October, 2003 - Xenova Group plc (NASDAQ NM: XNVA; London Stock
Exchange: XEN) today announced that it has initiated a second clinical trial for
TA-NIC, its therapeutic vaccine which is under development for the treatment of
nicotine addiction.

This second Phase I study builds upon the findings of a previous Phase I trial
which were announced in June 2002.  The results of this first study, which was
the first evaluation of an anti-nicotine vaccine in man, showed that the vaccine
generated a specific anti-nicotine response and that it was safe and well
tolerated both systemically and locally.  The objective of the new Phase I trial
is to further establish safety and tolerability, and to determine the
vaccination dose and schedule required to induce the optimal anti-nicotine
antibody response.  Three different doses of the vaccine will be evaluated.  The
impact of vaccination on nicotine-induced changes in heart rate and skin
temperature will also be monitored.

Approximately 60 smokers will be recruited into a double-blind, randomised,
placebo-controlled study which will be run at a European clinical centre
experienced in testing smoking related therapies.  Results of this study will be
used to design a Phase II trial that will assess the effect of vaccination with
TA-NIC on tobacco consumption.  This Phase II trial is expected to begin during
the second half of 2004.

Commenting on this new trial David Oxlade, CEO of Xenova Group plc said, 'TA-NIC
offers the hope of substantial benefit to smokers wishing to quit their habit.
With this new trial we will be directly assessing the impact of antibodies on
the physiological effects of nicotine.  It represents an important step forward
in strengthening the concept of vaccination as a treatment for nicotine
addiction.'
