Eligibility
Key inclusion criteria
Inclusion for Case

1. Male or female patients >=18 years of age with HIV-1 infection who experienced one or
more of the following adverse reactions within the first 8 weeks of starting
nevirapine therapy:

- Grade 3 or 4 LFT elevation (ALT or AST > 5X ULN) and any symptom consistent with
clinical hepatitis (see Appendix 10.1)

- Acute liver failure secondary to nevirapine therapy*

- Functional group III or IV rash

- *Acute liver failure is defined as serious liver injury usually requiring
hospitalization that may lead to death or liver transplantation.

Inclusion for Control

2. Male or female patients >=18 years of age with HIV-1 infection who have been exposed
to nevirapine therapy for at least 18 weeks and who do not meet any of the case
inclusion criteria
Minimum age
18 Years
Maximum age

Sex

Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion for Cases

1. Patients with any hepatotoxicity or rash event which in the investigators judgement is
not related to nevirapine use (ex. hepatotoxicity due to alcohol or other medicinal
use or rash due to other medicinal use).

2. Patients who began abacavir or TMP-SMX (trimethoprim/sulfamethoxazole) therapy 2 weeks
or less prior to or up to 8 weeks after initiating nevirapine therapy.

3. Patients with AST or ALT elevations > 5 times the ULN (>= Grade 3) just prior to the
initiation of nevirapine therapy.

Exclusion for Controls

4. Patients who discontinued nevirapine before completing 18 weeks of dosing with 200
mg/day for 2 weeks followed by 400 mg/day thereafter.

5. Patients who developed functional group I, IIa or IIb rash within 18 weeks of starting
nevirapine therapy, or any dermatologic condition that could plausibly be attributed
to nevirapine.

6. Patients with ALT or AST elevations >2.5 X ULN (>Grade 1) within 18 weeks of starting
nevirapine therapy.

7. Any hepatobiliary adverse event that could possibly be attributed to nevirapine.

8. Patients who develop any systemic reaction attributable to nevirapine use during the
first 18 weeks of nevirapine treatment such as flu-like symptoms, arthralgia, myalgia,
or conjunctivitis.

Exclusion for Cases and Controls

9. Patients who have participated in the 2NN-Long-term Follow-up study (1100.1454)

10. Patients with CD4 count 150 cells/mm3 prior to the initiation of nevirapine therapy
(last available result measured 6 months prior to the initiation of nevirapine
therapy).

11. Evidence of acute co-infection with viral hepatitis.

12. Patients taking prednisone, prednisolone, or immuno-modulatory medication within the
first 8 weeks of nevirapine therapy.

13. Patients who are unwilling to provide blood samples for DNA testing.

14. Patients who did not sign informed consent and or authorization to release protected
health information per local requirements.

15. Patients without available liv
