cancer, patient must be disease free for at least 5 years. Patients with other prior
malignancies less than 5 years before study entry may be enrolled if they received
treatment resulting in complete resolution of the cancer and have no current
clinical, radiologic, or laboratory evidence of active or recurrent disease.

- Human immunodeficiency virus (HIV)-positive diagnosis with a CD4 count of less than
100 mm3 or detectable viral load within the past 3 months, and receiving combination
anti-retroviral therapy.

- Diagnosis of Hepatitis B virus, or Hepatitis C virus with detectable viral load or
immunological evidence of chronic active disease or receiving/requiring antiviral

- Active central nervous system disease requiring treatment.

- Active uncontrolled infection, underlying medical condition, or other serious illness
impairing the patient's ability to receive protocol treatment.

- Discontinuation of prior oral bexarotene due to an allergic reaction or
treatment-related toxicity.

- Major surgery within 2 weeks of planned start of treatment.

- Conventional or investigational chemotherapy or radiation therapy encompassing
greater than 10% of bone marrow within 4 weeks prior to study treatment.

- ECP, phototherapy with PUVA, or ultraviolet (UV) therapy within 2 weeks prior to
study treatment.

- Systemic corticosteroids within 3 weeks of study treatment, unless patient has been
taking a continuous dose of no more than 10 mg per day of prednisone or equivalent
for at least 4 weeks.

- Initiation of or change in dosage of topical corticosteroids within 3 weeks of study
treatment (topical steroid use within 3 weeks is allowed provided the strength and
use has been stable for at least 4 weeks).

- Investigational drugs, biologics, or devices use within 2 weeks prior to study
treatment or planned use during the study.

- Monoclonal antibody within 3 months without evidence of PD.
