                    Welcome back.
                  
                    I'm pleased to see that
                  
                    you have joined for
part two of this talk
                  
                    in which I will discuss further
                  
                    the roles of oncolytic viruses,
                  
                    toll-like receptor agonists,
                  
                    and STING agonists in
                  
                    the treatment of
patients with cancer.

                    Now, I go on to discuss
                  
                    the clinical development
of the RP platform.
                  
                    This has been tested
in patients with
                  
                    a range of different
tumour types including
                  
                    cutaneous melanoma,
                  
                    even in a group of patients who
                  
                    have previously received
and progressed following
                  
                    anti-PD1 therapy.
                  
                    Here, I show you the design of
                  
                    a study in which patients
initially received
                  
                    a first dose of virus and then
                  
                    virus in combination
with nivolumab for
                  
                    a number of cycles,
                  
                    up to 30 cycles
of treatment with
                  
                    Opdivo or nivolumab with
patients being followed for
                  
                    safety but also to assess
                  
                    the efficacy of
the RP1 platform.
                  
                    Remember please that these
are patients who have
                  
                    previously shown progression
on anti-PD1 therapy.

                    Here, you see the breakdown of
                  
                    the demographics
of these patients.
                  
                    You can see that
there were initially
                  
                    16 patients treated in
                  
                    the first cohort and then
                  
                    there was an expansion cohort of
                  
                    a further 75 patients,
                  
                    leading to a total
population of 91.
                  
                    All of whom had received
prior anti-PD1.
                  
                    Some of whom had received also
                  
                    anti-CTLA-4 and other therapies.
                  
                    You can see the breakdown there.
                  
                    This is a group of patients with
                  
                    very advanced disease,
                  
                    the vast majority being
stage 4 melanomas in
                  
                    both of these groups and
                  
                    over a quarter of the
patients having had
                  
                    a high level of LDH above
the upper limit of normal.
