NBC has announced open casting call dates and locations for The Biggest Loser's ninth season, which is currently slated to air early next year.

The 15-city cross-country tour will begin June 27 in Chicago and end August 1 in Los Angeles -- with additional stops in Detroit, San Jose, Tampa, Atlanta, Mobile, New York City, San Antonio, Dallas, Kansas City, Philadelphia, Phoenix, Oklahoma City and Des Moines.

Similar to The Biggest Loser's Fall 2008 sixth season, the ninth season will be a The Biggest Loser: Families edition which will feature pairs of family members such as parent and child, couples and siblings teams.

In addition, candidates must be at least 18 years of age and legal residents of the United States.

NBC announced in January that it had renewed The Biggest Loser for two more editions, with the show's eighth installment slated to premiere in September.

Open casting calls for The Biggest Loser eighth-season contestants -- as well as certified trainers interested in participating in the series -- were held earlier this year
