The Change in AK Count From Randomisation to 8 Weeks After Randomisation8 weeks after randomisation

The change in AK count from randomisation to 8 weeks after randomisation was determined for the field recalcitrant and the field recurrent subgroups

Number of Participants With Complete Clearance Through to Month 12, Defined as no Clinically Visible AKs and no Lesions Treated in the Selected Treatment Area at Any Time From Last Treatment Cycle Through to Month 12From last treatment cycle through to Month 12
