According to the illustrator, the theft occurred while the drafts were being transported to the inker.
Moore went on to say that he has high-resolution back-up scans, so production on the Marvel title can continue. However, the artist made a plea to art dealers and collectors - who may come into contact with the pages - via his Twitter account.
"5 of my Venom #1 pages have been stolen. Art dealers and collectors please keep an eye out as I would like to have them back," he wrote.
Written by Rick Remender, Venom #1 sees long-time Peter Parker rival Flash Thompson bond with the alien symbiote and take centre stage.
The comic arrives in stores next month.
