http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/Drugs/PsychopharmacologicDrugsAdvisoryCommittee/UCM177119.pdf

Slide #40 D/C's with 3 weeks of Rx
179 subjects (3.3%)

ALT increased 2
AST increased 1
Hepatic enzyme increased 1
Liver function test abnormal 1
Transaminases increased 1

LFTs inc 3 x ULN including non-DCs
~1/8 (12.1%) (approx 80 subjects)

Background package 2 children dead due to hepatic steatosis, 16 yo - 2 yrs of Rx and a 3 yo.

Tom Laughren FDA Psychiatry Division Director

"There were liver enzyme increases for olanzapine, although I would point out that even though olanzapine has been out there now for, I think probably 13 years, . And we do see transaminitis for a number of drugs that are out there, drugs that never turn out to be significant hepatotoxins. But there's clearly a signal for
transaminitis for this drug."

Laughren's final recommendation:

Olanzapine 2nd line b/c of weight gain.

Comment:

2 children dead due to hepatic steatosis and Laughren says: "there hasn't been any signal emerged for severe liver toxicity"

Conclusion: Laughren doesn't count death as a signal.
