Inclusion Criteria

1) A biopsy compatible with the diagnosis of MF or SS with a CD4 positive phenotype within 6 months of study entry
2) MF stage IB to IVB (highest stage ever) or SS
3) Refractory to or intolerant to at least two prior therapies, one being Targretin® (or
combinations hereof), and the other being the current standard therapy at each
institution. Stage 1 patients are only required to be refractory or intolerant to at least one prior current standard therapy

• Refractory is defined as:
- resistance to therapy due to lack of response (defined as failure to obtain at least a 50% reduction in the disease for at least 6 months)
- progression of disease (defined as worsening of the disease by 25% or more compared to pre-treatment status) during therapy or within three months after cessation of therapy

• Intolerance to prior therapy is defined as:
- Discontinuation of therapy due to side effects/toxicity of the therapy. Patients who are intolerant to a therapy and who have had a clinically meaningful response (defined as greater than a 50% reduction in disease) should not be enrolled until disease progression is documented (defined as worsening of the disease by 25% or more compared to the nadir after treatment was discontinued due to intolerance). Side effects/toxicity of Targretin therapy which qualify for the intolerance criteria are isolated hypertriglyceridemia or combined hypertriglyceridemia/hypercholesterolemia despite concomitant administration of anti-lipemic therapy, defined as:
a) Isolated hypertriglyceridemia defined as Triglycerides > 400 mg/d
b) Combined hypertriglyceridemia/hypercholesterolemia for non-diabetic patients
Triglycerides > 200 mg/dL plus LDL cholesterol > 160 mg/dL or Triglycerides> 200 mg/dL plus HDL cholesterol < 40 mg/dL
c) Combined hypertriglyceridemia/hypercholesterolemia in diabetic patients (type I and II): Triglycerides > 150 mg/dL plus LDL cholesterol > 130 mg/dL or Triglycerides >
150 mg/dL plus HDL cholesterol < 40 mg/dL
Other side effects/toxicities of Targretin, which qualify for the intolerance criteria:
d) ALT > 3 times upper limit of normal
e) AST > 3 times upper limit of normal
f) Bilirubin > 3 times upper limit of normal
g) NCI grade 3 leucopenia
h) Uncorrectable hypothyroidism
i) Drug related dermatitis

• Ineligibility (as part of the intolerance criteria) to treatment with Targretin® despite
administration of anti-lipemic therapy or due to concurrent medical conditions, such as:
- Isolated hypertriglyceridemia or combined hypertriglyceridemia/hypercholesterolemia, defined as:
a) Isolated hypertriglyceridemia defined as Triglycerides> 400 mg/dL
b) Combined hypertriglyceridemia/hypercholesterolemia in non-diabetic patients defined as Triglycerides > 200 mg/dL plus LDL cholesterol > 160 mg/dL or
Triglycerides> 200 mg/dL plus HDL cholesterol < 40 mg/dL
c) Combined hypertriglyceridemia/hypercholesterolemia in diabetic patients (Type I
and II): Triglycerides > 150 mg/dL plus LDL cholesterol > 130 mg/dL or
Triglycerides > 150 mg/dL plus HDL cholesterol < 40 mg/dL
- Prior pancreatitis
- Recurrent biliary colic
- Known hypersensitivity to retinoids
- Incapability to swallow Targretin capsules
