Staff at the University of Cincinnati Medical Center tried to resuscitate Otto but the patient ultimately succumbed to a heart attack, according to doctors. Justin Weber said Tuesday morning that a news conference is expected later to provide details.
Doctors caring for Warmbier said the 22-year-old was experiencing "unresponsive wakefulness," a term that has come to replace the "persistent vegetative state".
Warmbier was detained at the Pyongyang airport in January 2016, charged with a "hostile act" against the country's authoritarian government and convicted less than two months later of trying to steal a propaganda poster.
He was sentenced in March 2016 to 15 years in prison with hard labor. The company says the "tragic outcome" of Warmbier's trip - the American died after being jailed and had been in a coma - prompted the change. But some analysts believe negotiations could happen because of USA worries about the safety of the three other Americans still detained in North Korea.
Warmbier grew up in the Cincinnati suburb of Wyoming. North Korea accuses Washington and South Korea of sending spies to overthrow its government.
"This might be America's biggest idiot frat boy: Meet the UVa student who thought he could pull a prank in North Korea", read the site's headline. "But we choose to focus on the time we were given to be with this remarkable person", the family said in a statement.
An initial inspection of the student's body has found no marks of physical injury, nor have USA doctors found any evidence that he had contracted botulism.
The North Koreans have claimed that Warmbier's condition was due to a case of botulism that he contracted after his trial, combined with the effects of a sleeping pill.

The U.S. State Department strongly warns Americans against traveling to North Korea, saying they're "at serious risk of arrest and long-term detention under North Korea's system of law enforcement".

"I believe we must now have the perception that North Korea is an irrational regime". They did not cite a specific cause of death.
"It's unsafe", Corker said, adding that the "trumped up charges" like those Warmbier was accused of "can continue to happen". "Surrounded by his loving family, Otto died today at 2:20pm".
Ojea-Quintana had called on Pyongyang on Friday to explain why Warmbier was in a coma when he was returned home after being denied access to legal and consular services. "And I believe there are voices supporting such a step-by-step approach even within the United States", he said, according to the USA channel.
Pyongyang has vowed to develop a nuclear-tipped intercontinental ballistic missile capable of hitting the US mainland.
Doctors also found no evidence of broken bones or other injuries that would suggest Warmbier was physically abused - though cuts and bruises would have had plenty of time to heal.
"We plead with the USA government, the global community, and leadership in North Korea to value human lives".
