Comedy Central, which helped to redefine late-night satire with “The Daily Show,” its topical 11 p.m. series, continues to struggle in its efforts to find an 11:30 p.m. companion for that program.

On Friday, the network said it was canceling “The Opposition With Jordan Klepper” after a run of about nine months. “The Opposition,” which made its debut last September, had starred Mr. Klepper, a former correspondent for “The Daily Show,” as an incendiary, conspiratorial broadcaster in the vein of Alex Jones. “The Opposition” will end after its June 28 episode, Comedy Central said.

Kent Alterman, the Comedy Central president, told Deadline that the show’s cancellation had come at a time when the network was deciding whether to renew the contracts of the people involved with “The Opposition” and eager to move Mr. Klepper into a new show.

But ratings for “The Opposition” had been mediocre. Last week, it shed more than half of the “Daily Show” audience, drawing an average of 330,000 viewers compared to 790,000 for the earlier program, according to Nielsen.
