Extern said it had been told the Intensive Family Support Service (IFSS) must close.
Charlie Mack of Extern said the staff had worked "tirelessly" to help vulnerable children.
The Department of Health said families would continue to be supported.
"Sadly we are the victims of not having a government in Northern Ireland at the moment," Mr Mack told BBC Radio Ulster's Evening Extra.
"All of the leaders of all the political parties (in Northern Ireland) have said it would be morally wrong if this service was stopped.
"As late as this afternoon we were pleading with the permanent secretaries to reconsider."
In a statement, the Department of Health said the pilot had "now come to an end and work has already started to consider how we successfully apply the learning identified".
"Families will continue to be supported by statutory services," the statement added.
"No cuts have been applied to any services.

"I've said on several occasions when asked about him that there's nothing I can teach him about goalkeeping, or how to recover and train."

Researchers in Bristol found 8% more patients died after 30 days if they were operated on between 24 and 36 hours after admission to hospital.
The delay is thought to have caused 670 excess deaths in four years.
Project leader Timothy Chesser said it was the "first time" the benefits of early surgery had been revealed.
Data was collected by a team at Southmead Hospital from the National Hip Fracture Database, the largest such list in the world.
The study focussed on 241,446 patients across England and Wales who were admitted to hospitals with hip fractures between January 2011 and December 2014, and the mortality rate for these patients 30 days after they were admitted.
Guidance issued by the National Institute for Health and Clinical Excellence in 2011 called for patients to be operated on either the same day, or the day after, hospital admission.
But the new report says that even earlier surgery can improve outcomes for elderly patients who are often frail, with multiple medical problems.
"We found 8% more patients died if they were operated on between 24 and 36 hours compared to those given surgery within 24 hours, and the risk increased to 20% for those receiving surgery after 48 hours," said Adrian Sayers, the lead author on the paper.
Timothy Chesser, the clinical lead of the research project, said early surgery was not advisable for every patient, but was beneficial in the majority of cases.
"We have shown for the first time that early surgery is much better for patients," he said.
"The caveat is some of these patients are very sick and would benefit from greater time to get better before surgical procedures."
