The campaign will support the charity's partnership with the Tour of Britain, a free cycling event that takes place throughout the summer months.
The agency will create experiential, sponsorship, fundraising packs and PR activity for the charity, as well as providing consultancy and management for the event itself.
The activity will roll out at the end of this month, and continue until 19 September, when the event concludes.
John Neate, the chief executive of The Prostate Cancer Charity, said: "This partnership represents a really exciting new chapter in the life of the charity and a great opportunity for us to raise awareness, funds and gain support on a local and national level."
The organisation's most recent advertising campaign featured the broadcasting family Jon, Dan and Peter Snow posing in their underpants in support of Prostate Cancer Awareness month.
