The programme has been announced just weeks after the channel broadcast Exposure: The Other Side of Jimmy Savile, which first brought the allegations surrounding the late broadcaster into the public domain.
ITV Studios are said to be working once more with journalist Mark Williams-Thomas on the follow-up programme for its its Exposure series of shows, reports Broadcast.
The documentary will likely focus on further allegations about Savile's actions, while a police investigation is following claims that he abused around 300 people over 40 years.
However, it is reportedly unlikely to look into the separate investigation being held at the BBC and its cancelled Newsnight special last year.
An insider said that the programme will "pull together everything we have found", and will air in November.
The first Exposure documentary was seen by 2.27 million people and had a share of 23.94% of the audience on the night.
The BBC's Panorama special of the corporation's handling of the Savile allegations drew an even bigger audience of 5.09 million last week.
Savile's estate had reportedly denied access to BBC clips of the late star, but they are said to have lifted the ban for the second show if the BBC grant permission.
Tom Stone will produce the follow-up programme, with Alexander Gardiner executive producing.
A recent poll has suggested that the BBC are to suffer "lasting damage" to its reputation following the Jimmy Savile scandal.
