The purpose of this research study is to determine if the new drug resminostat will be able to delay or prevent worsening of disease in patients with advanced stage mycosis fungoides or S?zary Syndrome that have achieved disease control with previous systemic therapy, recently

1. Patients with histologically confirmed MF (Stage IIB IVB) or SS in an ongoing CR, PR or SD after at least one prior systemic therapy according to local standards (including but not limited to a-interferon, bexarotene, extracorporeal photopheresis, chemotherapy) or total skin electron beam irradiation,
othe most recent systemic therapy must have been completed as planned or stopped due to unacceptable toxicity 2 12 weeks prior to randomisation, i.e. patients should not be withdrawn from a treatment from which they derive benefit

5. Adequate haematological, hepatic and renal function, as demonstrated by:
a)haemoglobin = 9.0 g/dl (International System [SI] of Units: 5.6 mmol/L)
b)absolute neutrophil count = 1,000/mm3
c)platelets = 75 ? 109/L
d)alanine aminotransferase and aspartate amino-transferase = 2 times upper limit of normal
e)total bilirubin = 2 mg/dL (SI units: 34.2 ?mol/L) (unless known Gilbert syndrome)
f)serum creatinine = 1.5 mg/dL (SI units: 132 ?mol/L)
g)prothrombin time International Normalised Ratio = 2.3
6. Women of childbearing potential (not post-menopausal for 1 year and not surgically sterile) and males with partners of childbearing potential must be sexually abstinent (i.e. refraining from heterosexual intercourse) or must use a highly effective contraception (at least one of the following: combined (oral, intravaginal or transdermal) or progestogen-only (oral, injectable or implantable) hormonal contraceptives, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomy of the partner from the time of screening to 30 days (female patients) or 3 months (male patients) after the last dose of trial treatment
7. Adequate recovery from precedent non-haematological toxicities, excluding alopecia, to = National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Grade 1
8. Able to comply with all the requirements of the protocol

Exclusion criteria:

3. History and current cardiovascular complications, including unstable angina pectoris, uncontrolled hypertension, congestive heart failure (New York Heart Association [NYHA] Class III or IV) related to primary cardiac disease, a condition requiring anti arrhythmic therapy, ischemic or severe valvular heart disease, or a myocardial infarction within 6 months prior to randomisation
4. Baseline corrected QT (QTc) interval > 500 milliseconds [NOTE: QTcF is relevant]
5. History of additional risk factors for Torsade de Pointes (e.g., heart failure, hypokalaemia, family history of Long QT Syndrome)
6. Use of concomitant medications that are known to prolong the QT/QTc interval
7. Concurrent use of any other specific anti tumour therapy including psoralen photo chemotherapy (PUVA), chemotherapy, immunotherapy, hormonal therapy, radiation therapy, or experimental medications
8. Previous or concurrent cancer that is distinct in primary site or histology from CTCL, except curatively treated squamous-cell carcinoma of the skin stage 0-1 and curatively treated melanoma stage 0-1A with a low risk of recurrence/metastasis as per assessment of the investigatorcervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumours (Ta, Tis and T1); any cancer curatively treated > 3 years prior to randomisation will be allowed
9. Current evidence of any uncontrolled clinically significant internal, psychiatric or neurologic disease
10. Altered mental status precluding understanding of the informed consent process and/or completion of the necessary trial procedures
11. Pregnant or breast feeding women
12. History of allergic reactions attributed to compounds of similar chemical or biological composition to the trial drugs
13. Active alcohol and/or drug abuse
14. Any other acute or chronic condition that, in the investigator?s opinion, would limit the patient?s ability to complete or participate in this trial
