The independent comic, created by writer Montynero and artist Mike Dowling, tells the story of three Londoners granted superpowers and six months to live by a sexually-transmitted virus.
"Death Sentence has it all - a great high concept, engaging characters, fantastic art and gripping writing. Montynero has a spectacular career ahead of him - and Mike Dowling's self-coloured work is a revelation," said editorial manager Andrew James.
Millar, who discovered the title at his Kapow! Comic Convention, described it as "genuinely original" and "just brilliant".
An announcement about "exciting news on the future of CLiNT" will be made in January next year, according to a statement released by the publication.
Death Sentence will debut in CLiNT on May 10, 2012.
